ANDRITZ launches D-TECH technology for production of respiratory facemasks

Following its launch of the D-TECH line for production of surgical/medical masks in April 2020, ANDRITZ is now presenting its new D-TECH line for respiratory masks, such as duckbill and flat fold respirators.

The new ANDRITZ D-TECH respiratory mask line can be customized to laminate different layers of fabric, ensuring highest quality and hygiene standards. The line comprises unwinding and guiding units for nonwoven webs, automatic splicing of all raw materials, cutting and positioning devices for the metal nose bar, an edge welding and cutting unit, a 90° rotation process, positioning and welding of the ear loop elastics, as well as quality control using the D-TECH Vision System. Machine dimensions can be customized according to customers’ plant requirements.

Customers benefit from a fully automated production line including complete ultrasonic technology, a facility to include printing systems, and an interface to the automatic packaging machine. Moreover, there are different packaging options available – products can be packaged in bags by an automatic flow pack machine or packed in cardboard boxes by an automatic cartoner.

The respiratory mask line ensures a higher level of protection for the wearer as well as his environment due to its particle retention capacity (<0.3 µm) and the higher-quality defined total leakage compared to conventional protective masks. Producers already operating an ANDRITZ D-TECH surgical mask line can upgrade it to produce respiratory masks with a special kit.


Two-layer polyester mask design shows 91.8% efficiency in Viral Filtration Efficacy test

Ed Goodwin, the founder and product development manager of HipSaver Inc., has always obtained scientific validation for all of his medical textile products. As such, he engaged Nelson Laboratories, to test his company’s DermaSaver Sci-Tex Mask construction.

“We believed our product would be effective based on the known textile science, and now these results from Nelson Labs have proven that to be true,” says Goodwin. “Virus transmission experts agree that exposure duration and dose volume of virus particles are two key factors in overwhelming the immune system. This test result shows a dramatic reduction in the dose volume exposure.”

Viral Filtration Efficacy (VFE) test showed the DermaSaver Sci-Tex Mask material construction to be an average of 91.8% effective in preventing aerosolized virus particles from penetrating through the mask. The virus particles tested are five times smaller than COVID-19 virus particles, implying that the efficacy against preventing COVID-19 virus particles from penetration could be even greater.

The mask, which retails for less than $20, consists of two layers of water resistant (hydrophobic) microfiber polyester that repels airborne droplets. The brushed inside surfaces of the layers mesh together to create an additional barrier.

Study shows commercial air filters reduce presence of airborne particles with coronavirus

Surges in COVID-19 cases have accelerated research to find ways to reduce the spread of viruses, especially as airborne transmission seems more likely.  American Air Filter, Co. Inc., and its subsidiary Flanders Corp. tested the effectiveness of its commercial air filters against a type of coronavirus, the Porcine Epidemic Diarrhea (PED) virus.  The tests, conducted at the company’s Clean AIR Center in Jeffersonville, Ind., confirm that its commercial air filters reduce the presence of this virus surrogate in airborne particles, including in sizes similar to airborne droplets produced when a person sneezes, coughs or speaks.

The study was adapted from University of Minnesota research that showed a correlation between particle filtration and virus removal. That study used a porcine virus half the size of a typical coronavirus and used airflows much slower than are typical for a commercial system. AAF Flanders conducted this new research using PED virus, a member of the coronavirus family that behaves similarly, when airborne, to the virus that causes COVID-19.

Virus particles marked with a fluorescent dye were mixed with other airborne particles and drawn through individual air filters in test ducts at an airspeed mimicking commercial HVAC system airspeed. Samples of airborne particles were then collected upstream and downstream of the filter. Nikki Goss, M.S., manager of Biological Safety and Research, found that AAF Flanders air filters reduce the presence of the PED virus at approximately the same rate as overall particle removal.

“We have always been leading the way forward when it comes to filtration, but we never expected our expertise could aid in fighting a pandemic,” said Nathanial Nance, VP of Global R&D. “We take pride in knowing our products could reduce the risk of virus transmission.”

*AAF Flanders makes no claims regarding the ability of its filters to remove airborne SARS-CoV-2. Test results should be viewed as directional and real-world performance is environment-dependent. Methodology was based on prior tests comparing standard ASHRAE 52.2 testing to predictive analysis based on virus carriers.

University of Cambridge Institute for Manufacturing working on dual, shared ventilator technology

In response to the COVID-19 pandemic, volunteers from the Institute for Manufacturing (IfM), University of Cambridge, responded to a request from clinicians at Royal Papworth Hospital to develop a device that, if needed in an emergency, could be attached to a ventilator to enable two COVID patients to receive tailored respiratory support.

Due to the success of the Government’s Ventilator Challenge UK, Royal Papworth Hospital NHS Foundation Trust, along with other NHS hospitals, received enough ventilators to meet the surge in demand from COVID-19 patients and continue to have a healthy reserve stock of ventilators.

However the new device – which is still in testing and not yet approved for clinical use – illustrates that it is possible to split the air flow from one ventilator to mechanically support the breathing of two sedated patients with different lung capacity and changing breathing needs.

  • The new device, which is being developed in collaboration with Cambridge Design Partnership, improves upon and addresses concerns about previous ‘ventilator splitter’ designs, allowing one ventilator to be used by two patients more safely.
  • The system incorporates respiratory parts that are available in the UK supply chain and which can be easily changed and replaced.
  • Full design and testing details will subsequently be released so that the system can be developed for use in other countries.

WHO issues updated brief on modes of transmission for COVID-19

The World Health Organization published a document updating its scientific brief published on March, 29 2020, entitled “Modes of transmission of virus causing COVID-19: implications for infection prevention and control (IPC) precaution recommendations.” The updated includes new scientific evidence available on transmission of SARS-CoV-2, the virus that causes COVID-19.

The brief provides an overview of the modes of transmission of SARS-CoV-2, what is known about when infected people transmit the virus, and the implications for infection prevention and control precautions within and outside health facilities. This scientific brief is not a systematic review. Rather, it reflects the consolidation of rapid reviews of publications in peer-reviewed journals and of non-peer-reviewed manuscripts on pre-print servers, undertaken by WHO and partners. Preprint findings should be interpreted with caution in the absence of peer review, according to WHO.

The brief covers modes of transmission for SARS-CoV-2, including contact, droplet, airborne, fomite, fecal-oral, bloodborne, mother-to-child, and animal-to-human transmission.

European producers set for 20-fold increase in nonwoven facemask output by November

EU production of facemasks, essential for tackling the coronavirus crisis, is set to increase 20-fold by November this year compared to pre-crisis times. This means that EU-based producers will be able to make the equivalent of 1.5 billion three-layer masks a month, according to figures released by EDANA, the global association serving the nonwovens and related industries.

Over the last three months, EDANA has been liaising with partner associations including MedTech Europe, ESF, and EURATEX to ensure sufficient supplies of essential public health equipment. EDANA convened a new sector group representing face mask converters, nonwoven suppliers, testing laboratories and equipment manufacturers to work together to develop an independent and self-sufficient supply chain for medical face masks and personal protective masks in the EU. The group will work to ensure adherence to applicable European Standards and to encourage responsible product stewardship throughout the life-cycle of face-masks from raw material sourcing to end-of-life solutions.


Ahlstrom-Munksjö partners with sportswear company to provide filter media for facemasks

Ahlstrom-Munksjö established a partnership with Spanish sports and life style accessories company BUFF to provide filter media for face masks.

The BUFF facemasks are now available in the United States and Canada following a launch in Europe in June. Each BUFF facemask includes five single-use filters in the original packaging. Replacement filters are sold separately in packs of 30 units.

The spread of COVID-19 and the consequent increase in the global demand for facemask components required many companies to rapidly adapt, leverage on their expertise and innovate. Thanks to Ahlstrom-Munksjö’s long-term experience in the manufacturing of filter media and protective medical fabrics, the company has developed a new material suitable for Type II facemask applications. Leveraging on its capabilities and adapting its converting and packaging processes, Ahlstrom-Munksjö has established a partnership with BUFF to supply its replaceable filter media which is included in BUFF’s new range of facemasks.

Tests conducted on these new single-use filters have shown a 98% bacterial filtration efficiency and meet EN14683:2019 Type I & II standards. The new BUFF Filter Mask is lightweight, ergonomic and easily adjustable. Its features make it ideal to be worn also during sport and outdoor activities, protecting the user yet allowing a high level of comfort.

Camfil launches CamCleaner CC500 portable air purifier, targeting COVID-19 applications

Camfil, an air filtration research and engineering group, has launched the CamCleaner CC500. With HEPA filters thoroughly tested to a minimum of 99.99% efficient, and a 5-star MERV 9A pre-filter, the CamCleaner CC500 can be used as a portable air purifier or as a ducted negative air system to protect patients, staff and visitors from airborne viruses, pathogens, and harmful particles. In the fight against the spread of COVID-19, it can be used in places such as patient/resident rooms, procedure rooms, isolation rooms, doctor and dentist offices and retail spaces. 

Some of the features of the CamCleaner CC500 include:

  • 99.99% true HEPA (high-efficiency particulate air) filter
  • Camfil 30/30 Dual 9 pre-filter, to extend the life of the HEPA filter
  • Easy access filter replacement

  • Bottom air intake with purified air exhausted through slotted vent cap or optional duct

    CamCleaner CC500 air purifiers with HEPA filtration efficiency for COVID. 

The air in COVID treatment areas should be kept separate from the air in other hospital areas so that infected air droplets don’t escape into uninfected areas. As air flows from higher pressure zones to lower pressure zones, negative pressurization is commonly used to control the spread of airborne diseases in hospitals. When the air pressure in an isolation area is “negative,” it’s lower than the air pressure of surrounding areas, which means that outside air can flow into the area, but not out. This helps prevent infections from spreading but introduces a need for high-efficiency filtration within the area because of the lack of airflow. The CamCleaner CC500 is designed for to provide clean air in these challenging environments and others where COVID, or air quality in general, is a concern. 


Considering pore sizes of surgical vs. respirator facemasks

Porometer has published an application note outlining test results using its POROLUX 100 porometer technology to test the pore size of surgical facemasks and N95 respirator facemasks. The application note explains how the pore size distribution of surgical facemasks and respirators can be measured using the “pressure scan” method employed by the POROLUX 100. The measurements show clear differences between the surgical mask and the respirator.

and a respirator (bottom). Photo: Porometer

Key findings include:

  • Both masks’ outside layers have considerably larger pores compared to their middle layers. The middle layer is hence often called the filtration layer. In both masks, the middle layer has a more narrow pore size distribution compared to the other layers.
  • Measurements show the differences between the middle layers of the surgical mask and the respirator, in terms of diameter and flow, respectively. The middle layer of the respirator has smaller pores than the middle layer of the surgical mask. The mean flow pore size (50% of the flow is through pores larger than the mean flow pore size) is smaller for the respirator (10.7 μm) than for the surgical mask (12.8 μm).
  • The measurements are highly reproducible, proving the value of the POROLUX 100 for quality control purposes.

Suominen’s new material for facemasks meets EN standard for filtration efficiency & pressure drop

Suominen has developed a nonwoven material for the manufacturing of facemask applications. The new nonwoven has passed European Standard EN 14683:2019 Type II requirements in terms of filtration efficiency and pressure drop.

“Our FIBRELLA Shield nonwoven has excellent filtration efficiency and pressure drop values meaning that the material provides protection while being comfortable and easy to breathe through. Measured with an applied method by VTT* results indicate that FIBRELLA Shield nonwoven’s filtration efficiency is higher than 99% reaching type II requirements but of course the material can also be used for lighter model Type I masks or uncertified masks,” said Category Manager, Johanna Sirén.

The standard EN14683:2019 for medical masks is for end products and the converter has to repeat the tests to confirm the standard compliancy for the end product. The end product needs to comply also with the regional regulations, if any.

Developed in cooperation with VTT, this new material is the latest addition to the FIBRELLA family. FIBRELLA Shield is already in production at Suominen’s Nakkila plant. Currently the plant is capable of producing material for approximately 15 million masks per month.

Study shows layered system of commonly available fabrics outperforms N95 respirator in filtration efficiency

A new study by Northeastern University found that a facemask constructed using fabrics manufactured by AKAS Textiles, a Pennsylvania-based textile manufacturer, outperformed an N95 respirator in an aqueous media under positive pressure of 20 Kilo Pascal, simulating a sneeze/cough. The study tested more than 70 different common fabric combinations and masks, including the N95 respirator, for their ability to block the transmission of virus-like nanoparticles. The mask with the best filtration was made of layers of ProCool Performance Fabrics combined with Zorb 3D Stay Dry Dimple fabric. The combination of these fabrics tested 72% more effective than the N95 respirator.

The study was published in ACS Nano, a monthly, peer-reviewed scientific journal published by the American Chemical Society. The authors wrote, “Layered systems of commonly available fabric materials can be used by the public and healthcare providers in face masks to reduce the risk of inhaling viruses with protection that is about equivalent to or better than the filtration and adsorption offered by 5-layer N95 respirators. The masks were evaluated with steady-state, forced convection air flux with pulsed aerosols that simulate forceful respiration.”

AKAS Textiles’ facemask materials

The study was done at 14 Liters per minute air flow, which is more than twice the human ventilation, at rest.

ProCool Performance Fabrics are two-sided fabrics, which are inter-knitted to provide filtration. The special wicking fibers in it help in managing the moisture. Zorb 3D Stay Dry Dimple is made with surface layers of wicking Stay Dry fibers with an innermost core of dense cellulosic fibers, which work as the filter. Th three-dimensional engineered pattern provides great filtration and keeps the mouth area dry and fresh, according to AKAS Textiles.

Research shows facemask textiles directly inactivate SARS-CoV-2

Researchers from Freie Universität Berlin at the Institute for Animal and Environmental Hygiene and the Institut für Textiltechnik (ITA) of RWTH Aachen University are collaborating on the topic of alternative personal protection equipment. The testing was conducted in the context of the EIT Health Project ViruShield, supported by the European Union, with the objective to discover alternative filter materials for facemasks in light of tight supply and globally imbalanced supply chains for personal protective equipment.

The Swiss company Livinguard has developed a treatment for textile facial masks that can directly inactivate bacteria and viruses, according to the researchers. While researchers at the Institut für Textiltechnik (ITA) of RWTH Aachen University conducted experiments on the chemical and physical properties of various textiles for face masks, researchers at Freie Universität Berlin were able to demonstrate that these new textiles can reduce high amounts of SARS-CoV-2 virus particles by up to 99.9% within a few hours.

The principle underlying the Livinguard Technology is that the textile surface has a strong positive charge. When microbes come into contact with the technology, the microbial cell, which is negatively charged, is destroyed, leading to permanent destruction of the microorganism. Unlike alternative metal-based solutions, the novel technology has been found to be safe for both skin and lungs. Moreover, Livinguard Technology is very sustainable, allowing users to reuse the mask up to 200 times with no reduced impact on safety or efficacy.

Lydall adds fine fiber meltblown line for filtration media for N95, surgical and medical facemasks

Lydall, a manufacturer of value-added engineered materials and specialty filtration solutions, announced an investment in an additional fine fiber meltblown asset in response to the exponential increase in domestic and global demand of specialty filtration media for facemasks. This new production line will enable Lydall – one of the few American manufacturers capable of producing high-quality fine fiber meltblown filtration media for N95, surgical and medical face masks – to significantly increase its supply and help alleviate the shortage of meltblown materials, both in the U.S. and internationally.

“In the wake of COVID-19, the need for the filtration media that makes face masks effective has increased dramatically, so much so that it is now being called the ‘golden fleece,’” Sara A. Greenstein, President and CEO of Lydall, said. “As one of the only companies in North America and Europe with the technical expertise, supplier relationships and access to the right machines to produce this filtration media, we feel great responsibility to do everything within our power to increase our output, support domestic supply chains and contribute to the global fight against COVID-19. This investment is one example of Lydall’s commitment to do just that.”

The new asset will complement Lydall’s existing global meltblown capacity and is estimated to supply the filtration media for one billion face masks per year, almost a third of the 3.5 billion that the U.S. Department of Health and Human Services has projected as necessary to protect healthcare workers. Lydall expects commercial production to begin in its Rochester, New Hampshire facility in the fourth quarter of 2020 and plans to hire up to 15 additional employees to support the increase in production.

Recommended wearing time of protective masks – researchers make better predictions possible with simulations

How long can you wear a protection mask? When will you have to change a soaked mask? Researchers of the Fraunhofer ITWM tackle these question using mathematical models and computer simulations. It is important to take into account not only the type of mask and the filter material, but also the physical stress level and personal features of the wearer.

Facemask Wear Time - Fraunhofer ITWM
Relative reduction of recommended wear time depending on intensity level and time share of physical stress. Reference value is the wear time at rest or light labour. In the present example, a hospital or a nursing care facility could deduce that staff members doing the most exhausting work need to change their masks up to five times more frequently than people working in the administration or at the reception. Image: Fraunhofer ITWM

A reliable protection does not only depend on the filtration properties of the mask material. It is known that moisture penetration decreases the filtering efficiency and therefore, the safety is reduced. Humidity and body heat enhance the microbial contamination on the wearer’s side of the mask. The most critical state is reached when the mask is imbrued entirely (moisture breakthrough), since the moisture can serve as an “infection bridge” spanning across the depth of the filter material. This holds for highly efficient filter masks (e.g. FFP-2), but even more so for masks to protect others. Coughing and sneezing can lead to the detachment of potentially infectious droplets from the outer surface, which will then spread into the vicinity.

Buildings in Boston are upgrading HVAC systems to prepare for COVID-19 reopening

Buildings in the Boston area are preparing for reopening by upgrading HVAC systems to prevent the spread of COVID-19, according to a report by Boston 25 News. The process is highlighting some challenges traditional HVAC systems face in preventing the spread of airborne viruses.

“When you recirculate that air, you have to be sure that air is going through a high-efficiency filter. Otherwise, any viral airborne particles will just be transmitted to another part of the building or an adjacent room,” Allen explained.

According to Allen, some property managers also plan to tinker with humidity levels. He said that is based on the concept that dry air in air-conditioned towers can more easily spread the virus.

“Relative humidity in a building is tricky because most building systems aren’t set up in a way that let you adjust relative humidity,” he said. “If you get it wrong, you can introduce conditions that lead to condensation and even mold growth.”

Denver-based screen company launches virus-filtering nanotechnology for filters and facemasks

Metro Screenworks, a Denver-based provider of retractable screen technology, introduced its VirusGuard virus-filtering material. VirusGuard can be utilized in several applications including creating masks, filters for masks, and constructing partitions and recently passed NH1 testing. VirusGuard is available in bulk rolls and ships internationally.

VirusGuard utilizes NanoScreen nanotechnology to restrict airborne, virus-carrying droplets, and is manufactured primarily to be made into masks and filters for masks. VirusGuard may help to increase the safety of personal masks as other safety materials may become scarce.

Metro Screenworks VirusGuard

VirusGuard comes in two types, Type 9001 and 9002. Type 9001 has three layers and can be cut, sewn, and inserted into pre-made facemasks. Type 9002 consists of five layers and is ready to be cut and sewn into PPE masks. Both types can be hand-washed without degrading their functionality, though machine washing isn’t suggested. A Virus Guard mask can be worn 30 to 40 days with proper care. VirusGuard comes in white and black, though black requires extra manufacturing time.

VirusGuard is manufactured to be used for disposable and reusable safety masks. However, it lacks the resistance required for other applications like creating quarantine partitions. Allergy Guard, a related product, has the same potential virus-blocking capabilities as VirusGuard, but can be utilized for other applications, like constructing safety barriers and window screens, as well as creating filters.


Considering MERV filter ratings & microbial filtration

Every filtration media is on a curve for filtration efficiency for particle sizes.  Efficiency is dictated by operating velocity, and one filter can have a higher efficacy based on lower operating velocities. As we consider filtration in the age of COVID-19, an article of interest is a bit of a blast from the past from Air Media, a publication produced by our friends at the National Air Filtration Association.

Airborne microbes can be removed by filters at rates that depend on the filter performance curve and the mean diameters of the microbes. Each microbial species has a characteristic range of sizes that forms a lognormal distribution between the minimum and the maximum. The following diagram shows the fractional efficiency of different MERV values, providing a sense for what is possible from a filtration perspective.

Chinese automakers introduce ‘virus-filtering’ air system

Chinese automakers are finding interesting ways to attract buyers after the major slump in car sales
caused by the Covid-19 pandemic. Chang’an Automobile — which operates joint ventures with the likes of Ford, Mazda, and Suzuki — shared on Wednesday that its “virus-filtering” air system for cars has reached mass production.
According to Chang’an, the high-efficiency filter can help keep passengers safer from pollutants and virus droplets in the air as they ride around town. The company received the CATARC CN95 certification back in April, meaning it can filter out 95% of particulate matter measuring 0.3 micrometers or larger. The company claims it can filter out particulate matter down to 0.1 micrometers. Most viruses, however, count their sizes in nanometers, which is a thousandth of the size of a micrometer.

ASHRAE issues guidelines for reopening buildings during COVID-19 pandemic

The ASHRAE Epidemic Task Force has developed guidance on mitigating potential health risks during reopening of buildings closed during the COVID-19 pandemic.

ASHRAE’s recommendations for reopening buildings are outlined in the frequently asked questions section of its COVID-19 Resources webpage. Recommendations for building readiness and reopening include the following:

  • Create a strategic plan prior to opening a building. The plan should include measures to make occupants feel safer, ensuring supply chain for critical items such as filters and communication plans for building support and safety measures for occupants.
  • If the building opening takes place when Personal Protective Equipment (PPE) requirements are still in place, ASHRAE’s Occupancy Guides can be referenced to deal with functioning buildings during the epidemic.
  • Review HVAC programming to provide flushing two hours before and post occupancies. This includes operating the exhaust fans as well as opening the outside air dampers. For buildings without the capacity to treat large quantities of outside air and when outside air conditions are moderate, open all windows for a minimum of two hours before reoccupation.
  • Ensure that custodial scope includes proper cleaning procedures built from EPA and CDC guidance on approved products and methods:
    • Disinfect high-touch areas of HVAC and other building service systems (e.g. on/off switches, thermostats)
    • Disinfect the interior of refrigerated devices, e.g. refrigerators, where the virus can potentially survive for long periods of time.
  • Run the system on minimum outside air when unoccupied.
  • Garage exhaust, if any, should run two hours before occupancy.

Techmer PM develops technology to help meltblown fabrics maintain electrical charge

As demand surges for facemasks during the COVID-19 pandemic, Techmer PM, LLC, has developed a technology to improve the efficacy of the fabrics used in the production of such masks.

The technology, called the Charge Enhancer, is used during the production of meltblown nonwoven fabrics to help the resulting masks meet the filtration performance requirements set forth by ASTM F2100.

Techmer PM provides its Charge Enhancer in pellet form to producers of meltblown nonwovens, who then add it to polypropylene in a concentration of 4- 5%.

As the extruded nonwoven comes off the production line in roll form, the material is subjected to an electrical charge via an air plasma treatment, also known as “corona” charging (no relation to the coronavirus). The Charge Enhancer technology helps the meltblown fabric enhance and retain the electrical charge imparted by corona charging.

“Without the Charge Enhancer, the mask media would struggle to retain a filtration efficiency of ≥95%,” said Bhushan Deshpande, Techmer PM’s vice president of technology.

Techmer PM is also testing new technology designed to provide more permanent charge-enhancing effects compared to what is currently available. “This newer technology will be well suited for mask manufacturers looking to develop reusable masks,” according to Deshpande.

Camfil develops respiratory facemasks to support COVID-19 response in Sweden

In response to the Coronavirus pandemic, Camfil is designing and developing respiratory protection masks at its laboratory located in Trosa Tech Center in Sweden along with other parts of Swedish operations. The initiative was raised to meet the demand for respiratory protection masks and its testing.

Since such face masks are not part of regular manufacturing output, Camfil kicked off a large-scale internal initiative with R&D. Product development in the filter industry usually takes several months or even years, but due to urgent demand Camfil redeployed production lines while finding partners and suppliers who could help make the idea a reality in a short time. Along the way, Camfil consulted with health care organizations and partners to produce the best possible product and plan for execution.

Camfil’s face mask prototype has been tested in the lab and shows highly promising results, according to the company. It has also been tested, in different versions, by the staff at Karolinska University Hospital, who have been very positive towards the quality of the product. Production is now in full swing, and our goal is to provide Region Stockholm with 100,000 CamProtect, respiratory protection masks per week, initially.


MIT professor explains test results showing some KN95 media provide filtration efficiency below 95% FDA mandate

As public health officials and others are working to secure personal protective equipment (PPE) to ensure the safety of health care providers and others working directly with COVID-19 patients. N95 respirators and facemasks, which are regulated by the U.S. government, have been in short supply, leading some entities and states to secure KN95 respirators as an alternative.

MIT Professor Gregory Rutledge

KN95 respirators are regulated by the Chinese government under specifications similar to N95 respirators in the U.S., and have been approved for emergency use in some circumstances by the FDA. (N95 respirators seal against the face and protect the wearer from small-particle aerosols in the environment. Face masks are not form-fitting but protect both the wearer and those around them from splashes and exchanges of large droplets.)

Recent tests conducted by the Massachusetts Manufacturing Emergency Response Team (M-ERT) in partnership with MIT have found that some of the KN95 filtration media in the states stockpile provides less than the 95% efficiency mandated by the FDA.

MIT Professor Gregory Rutledge participated in a Q&A to help explain the KN95 tests his lab conducted in cooperation with M-ERT.

Sulzer provides liquid-liquid extraction in manufacturing of COVID-19 medicines

Sulzer Chemtech is supporting Farmhispania Group to increase the production capacity of one of its drugs, which has proven its effectiveness in the treatment of critically ill COVID-19 patients. This will help the pharmaceutical manufacturer to meet rising global healthcare demands for the medicament. The key technology that will help intensify the manufacturing process as quickly as possible is Sulzer’s agitated Kühni column (ECR) for liquid-liquid extraction.

The urgency with which pharma businesses need to meet the rising demands of global healthcare production doesn’t provide sufficient time for them to significantly expand their operations by increasing their manufacturing footprint. For producers of antimalaria drugs, immunosuppressants and HIV medications, the pressure may be even higher, as these medicines are currently among the most promising treatments for the most critically ill coronavirus patients hospitalized in intensive care units.

Pharmaceutical ingredient manufacturer, Farmhispania, has found a way to address these challenges and produce more medicines suitable for coronavirus treatment. By working together with Sulzer, the leader in separation and mixing technology, the business will be able to ramp up its production capabilities in less than two weeks.

The two partners identified Sulzer’s ECR, a high-performance advanced extraction technology, as the most ideal solution. The separation system is particularly suitable for this project, as it can effectively handle a high flow rate, maximizing throughput.

KARL MAYER proving machines to manufacture up to 250k facemasks per month

KARL MAYER is working with industry partners to ramp up facemask production, leveraging its double needle bar raschel machine to enable the production of roughly a quarter of a million masks per month. The masks are produced entirely without the need of any sewing work. Two models are available for the various demands.

Type 1 is produced at short notice and is suitable for everyday life. Due to their 3D shape, these masks have a tight fit and good wearing properties. They offer a convenient air exchange, a soft skin feeling, and prevent friction points on the ears, even after long-term use. The masks can be reused after their utilization. Simply wash and dry them, and the next application can start immediately.

Type 2 provides all the advantages of type 1, but it can be equipped with a replaceable nonwoven lining via a pocket. This increases the filtration capacity, at the same time ensuring minimum waste after use.

Regarding the filtering effect, the certification process is currently underway for a medical standard for both mask types.

To ensure a fast use of the face masks in Germany, KARL MAYER equipped a customer with the required machine technology and the instructions for the production of the masks. The mask manufacture will start by the end of April.

Once the installed KARL MAYER machine is running at full speed, it is possible to produce up to 400 masks per hour or 240,000 pieces per month. At the same time, KARL MAYER is working on reducing the production time for additional machines, so that capacity can be increased as quickly as possible. By mid-May we can achieve a production of up to half a million masks per month.


Durst produces ‘community masks’ at Brixen headquarters

Durst, manufacturer of advanced digital printing and production technologies, is now producing “community masks” in its demo center at the Brixen headquarters in South Tyrol, Italy. The masks are produced in the first step for employees of Durst Group and sister company Alupress and afterwards the production capacity will also be available for other companies. The know-how for the production of the “community masks” will be made available to interested print service providers worldwide through its branches. 

“At the beginning of April, our printing technologies for the label and packaging industry were classified as systemically relevant and we were able to go back into partial operation,” said Christoph Gamper, CEO and co-owner of Durst Group. “Now we will also use our textile printing and processing systems, which are located in the demo center for customer demonstrations, for the production of “community masks”. In line with our “pixel-to-output” strategy, production takes place digitally and fully automatically: in a web shop with a specially programmed editor, the masks can be individualized with graphics, images, texts, and our workflow software then sends the designed file directly to the printing machine and then the printed material is processed by a cutting system. The announcement of our initiative on social media alone has generated great demand and print service providers worldwide are adapting our concept and thus Durst technology for their productions.”

The “community masks” produced by Durst have a filter membrane that has a high filtration efficiency and at the same time is characterized by very good air permeability. The “community masks” have a three-layer structure, the polyester fleece textile materials are comfortable to wear and washable, the filter membrane can be disinfected with alcohol and reused.

Durst explicitly points out that this is not a protective equipment in accordance with VO (E) 2016/425 or a medical device in accordance with Directive 93/42 / EEC.

Durst has many years of experience with filter systems, as these take on a type of “cleaning function” in the printing press to filter out microparticles in the ink supply systems so that the print heads do not become clogged and are always ready for use. The filter membrane selected by Durst Development for the “community.

NatureWorks, NWI partner to produce spunbond-based nonwoven material for N95 facemasks

As the world faces a critical shortage of personal protective equipment (PPE) for medical workers confronting the COVID-19 crisis, a long-standing partnership between NatureWorks and the Nonwovens Institute (NWI) at North Carolina State University (NC State) has resulted in a new spunbond nonwoven technology enabling the production of at least 10 million additional N95 surgical masks. NWI has converted the use of its research and training pilot production line to produce the face mask materials, and NatureWorks has donated the Ingeo resin needed to produce the spunbond material.

“Because of the COVID-19 crisis, we took the spunbond technology and created a new generation of unique filters that have excellent filtering capability without needing to be charged, meaning they can potentially be reused after cleaning with peroxide, or an alcohol solution,” says Behnam Pourdeyhimi, executive director of NWI, Wilson College of Textiles associate dean for industry research. and extension, and William A. Klopman distinguished professor. “Because these materials are also strong they can be cut and sewn by traditional techniques.”

The new nonwoven fabric is a bicomponent fiber made of Ingeo biopolymer (PLA) and polypropylene (PP), providing significant strength and bulk with equal effectiveness in filtration. Additionally, Ingeo improves the productivity of the spunbond process by at least 30%. Leveraging these benefits, NWI’s pilot line can produce enough material to make 2 million masks per week.

In accordance to the newly implemented guidelines issued by the French National Agency for the Safety of Medicines and Health Products (ANSM) aimed at providing policies that help expand the availability of face masks for non-sanitary use, Ahlstrom-Munksjö has received necessary certification for the use of its Reliance SMS 200, Reliance SMS 300, Reliance® Dextex 200 and Reliance Dextex 300 materials for facemask production. Typically used for the manufacturing of sterilization wraps for surgical instruments, these materials have been deemed to meet the requirements of a category 1 mask type for use by professionals in contact with the public. In addition, Reliance SMS 200 and Reliance SMS 300 have been shown to be compatible to the performance criteria of surgical masks.

The validation was acknowledged following a series of tests conducted by the Direction Générale de l’Armement (DGA), the French Government Defense procurement and technology agency. Testing  confirmed the performance compatibility of the Reliance SMS material with surgical facemask types thanks to its breathability and bacterial filtration efficiency, whereas Reliance Dextex proved to ensure permeability to air and to perform in protection barrier efficiency at a level compatible to the category 1 face masks currently in use.

Reliance SMS 200, Reliance SMS 300, Reliance Dextex 200 and Reliance Dextex 300 manufactured at the Medical business plants in Windsor Locks, United States and Mundra, India and converted at the site in Pont Audemer, France, have already been supplied to hospitals across France, to the French Government and distributors.


Johns Manville starts production of filtration media for facemasks at Richland, Mississippi plant

The Johns Manville plant in Richland, Mississippi, has started production to make nonwoven filtration media that will be used to create needed facemasks to help stop the spread of COVID-19.

Most nonwoven production of face masks was abandoned in the U.S. many years ago and moved to Asia. Given the shortage of face masks in the U.S. and Europe, JM’s Engineered Products business decided to build on its existing capabilities and help fill the market demand.

JM media meets or exceeds Level 1 BFE 95% (Bacterial Filtration Efficiency) and VFE (Viral Filtration Efficiency) requirements. These results were verified by an FDA-registered national laboratory.

The JM plant in Richland employs about 50 people and produces a variety of filtration products for various air and liquid applications using polypropylene and polyester meltblown technology. Richland’s meltblown filtration media can be found in numerous industrial, automotive, consumer products and FDA-approved food and healthcare applications.


Researchers develop self-sterilizing air filter that could be used for N95 and other facemasks

With the worldwide focus on coronavirus prevention and transmission, a new type of air-filter that self-sterilizes and decontaminates is being developed at Ben-Gurion University of the Negev in Beer-Sheva, Israel.

The new nanotechnology is based on laser-induced graphene (LIG) water filters that eliminate viruses and bacteria in water. This new concept, engineered for air-filtration could be used in air filters in heating, ventilation and air-conditioning (HVAC) systems or integrated into face masks for a self-sterilizing effect. Most masks will become contaminated during usage, including the N95 respirator mask, and if not properly used or handled, becomes a contamination risk.

Ben-Gurion University Researchers Develop Self-Sterilizing Filter

LIG is a microporous graphene foam that can be generated on many types of materials. LIG on water filters provide an active protection with simultaneous contamination removal and disinfection. The LIG is already resistant to bacteria and actively kills microbes and viruses using a low-level electric current from a power source. The researchers envision the two-fold protective system applied to air-filtration.

“The bacterial-resistant graphene surface protects against microorganisms so they can’t multiply, while the microbes trapped in the filter are eliminated by electrical effects.” says inventor Dr. Chris Arnusch, senior lecturer and researcher at the BGU Zuckerberg Institute for Water Research, part of the Jacob Blaustein Institutes for Desert Research.

The material can be completely sterilized by electrical current, thus an LIG air filter has the potential to be combined with state-of-the-art air filtration such as HEPA filters. The filters could add an active layer of protection, as well as prolong the lifetime of the expensive HEPA technology. As a result, hospitals, cars, buildings and public transport could all become safer spaces.

If such a material is incorporated into a mask a higher level of protection for medical providers, as well as the general population, could be possible, according to the researchers.


RKW joins coalition of manufacturers to produce FFP-2 protective facemasks

In response to the COVID-19 pandemic, RKW Group, Sporlastic, the Gherzi Consulting Group and others have formed the “FIGHT” consortium to jointly produce FFP-2 type protective masks.

RKW is participating in the production of FFP-2 protective masks by producing a laminate made of spunbonded nonwoven fabric at its Gronau, Germany facility. Production has been running at full speed for a few days now, with the aim of achieving a weekly capacity of around 750,000 masks.

The RKW spunbonded nonwoven is processed in Gronau into a laminate with meltblown material that meets the high demands on the filter material for FFP-2 masks. It must capture at least 94 percent of the particles in the air down to a size of 0.6 micrometers. The COVID-19 coronavirus is bound in water droplets averaging around 1 micrometer in size.

The first production batch will be delivered to the first client, the Ministry of Social Affairs and Integration of Germany’s federal state of Baden-Württemberg. Further public sector clients are currently in negotiation with the consortium.

After providing its own workforce with breathing masks, local companies and institutions of public interest, as well as private individuals, will be supplied. The Filtration Group would like to donate the first 10,000 masks to public institutions at its production sites. By producing breathing masks for private use, Filtration Group Industrial said it is aiming to help ensure that higher-quality, medically certified protective masks according to the FFP2 and FFP3 standard can continue to be used in hospitals and medical centers.


Coffee filter giant, Melitta, retools its production to manufacture up to 1M facemasks per day

As a contribution to supplying urgently needed breathing masks in response to the COVID-19 pandemic, coffee filter giant, the Melitta Group, is converting parts of its production to help fill the void. In the production of Melitta filter bags, breathing masks are now also being manufactured industrially and in large numbers at the company plant in Minden, Germany.

“With our production capacities, we are able to produce very large quantities of breathing masks in the shortest possible time,” says Jero Bentz, member of the Melitta management team. “For decades, our company has specialized in developing and producing other filter materials such as vacuum cleaner bags and other special industrial papers such as nonwoven wallpaper, primary materials for air filters — also for the medical sector — in addition to our filter bags.”

The result is a breathing mask in the form of Melitta’s filter bags, consisting of a three-layer fleece, which contains a meltblown layer that already fulfills the surgical mask standard according to EN14683 with a bacterial filtration efficiency (BFE)> 98%. In the first step, these masks are attached with a clip or rubber bands. The further development of the masks is planned in further expansion steps, with production of FFP2 and FFP3 masks also under development.

Melitta has already produced the first million masks. The existing capacities are expected to produce up to one million masks per day shortly. These quantities can be successively increased many times over, according to Melitta, provided the raw materials are sufficiently available. In addition to Germany, the Melitta Group also plans to use the existing production capacities in the U.S. and Brazil to manufacture breathing masks for North and South America.

McIlvaine touts reusable facemasks as alternative to social distancing

According to a report by McIlvaine Company, social distancing needs to be redefined from the common concept of staying six feet apart of other individuals or the space they have occupied in the last 60 seconds. This current definition creates great barriers to normal life. The safety of social distancing can be alternatively provided with a program that will have comfort and social acceptance along with affordability. This is now possible because of new filtration media, testing, decontamination and other technology innovations.

It starts with  the fact that a washable highly efficient mask can be provided.

There are retail stores in China that sell nothing but these masks with many fashionable varieties. With an integrated valve, they are both comfortable and stylish. They are also washable. These are $30 masks, which if worn 60 times, would cost $.50 per wearing. There are less expensive designs available as well. Chinese companies are also producing washable N95 masks with and without the valve feature. Over the last few months, the production these masks has expanded to several million per day, and since they are washable the cost per wearing is as low as 10 cents.

What You Need to Know About Air Purifiers and the Coronavirus

Running an air purifier at home can be a good idea anytime, to help filter out indoor allergens and pollutants like fumes from cooking and cleaning products. Especially now, when so many people are stuck indoors 24/7 because of the pandemic.

But can an air purifier prevent COVID-19 by capturing virus particles that could be traveling in the air?

We spoke with air quality and virology experts, and asked CR’s own experts to weigh in. The consensus is that while air purifiers probably don’t offer much protection in most circumstances, they may be worthwhile in a few specific ones.

Ahlstrom-Munksjö ramps up medical fabrics production to provide up to 30 million face masks per month

Responding to the COVID-19 pandemic, Ahlstrom-Munksjö has increased capacity across its entire protective medical fabrics product portfolio. The exponential spread of the COVID-19 virus around the world has caused an exceptional situation, creating strong demand for healthcare goods in general, and specifically for protective medical products that are made from the company’s fabrics. Ahlstrom-Munksjö is also expanding manufacturing of fabrics production lines normally used for producing other fiber-based materials.

In the beginning of March, the company expanded the production of face mask materials to a fine fiber line normally used for industrial filtration materials at the Turin plant, Italy. The technology is unique, generating good protection and breathability for medical use, and approved as a surgical mask. The advantage of this technology compared to the commonly available electrostatically charged material is its durability. Protection efficiency of electrostatically charged materials is lost overtime when humidity gets in contact with the filter media, whereas protection efficiency of a mechanical filter media remains intact over time. First orders were received in the middle of March, and Ahlstrom-Munksjö is now targeting to ramp up fabrics production for more than 20 million face masks per month.

In April, Ahlstrom-Munksjö is expanding the production of face mask materials to a line normally used for industrial filtration materials at the Tampere plant in Finland. Currently the material is well suited for lighter fabric face masks in civil activities. Droplets test shows that the media has efficiency above 90% at 3 microns and above 85% at 1 micron, which is close to a surgical face mask requirement. Development continues to meet the requirements of material for surgical masks for medical use. Considering the ongoing production, the Tampere plant can deliver fabrics for around 10 million face masks per month on a short notice.


Reifenhäuser calls for the creation of industrial supply chains for face masks in Europe

Reifenhäuser Reicofil recently opened its R&D facility to the manufacture of nonwoven fabrics for face masks and medical protective apparel to support the COVID-19 response. However, the company says the utilization of this material is under-performing, with only small-scale, manual conversion of the material into face masks for end use.

“Within the last two weeks, many initiatives have been founded that sew masks by hand. Thus, at least small production capacities have been established in Germany within a very short time, which now want to be supplied,” said Bernd Kunze, Ph.D., managing director of Reifenhäuser Reicofil. “From the many inquiries we have very consciously selected those initiatives that work efficiently and deliver masks quickly and reliably first to where they are most urgently needed.”

For Reifenhäuser, however, manually operating converters remains only a partial success, as the quantities produced in this way are only a small amount of the overall demand for medical protective clothing. Likewise, the company notes that if the general population is to be supplied with masks, the demand would rise into the billions. To actually solve the problem, the company said Germany and Europe need to establish their own industrial production sites with closed European supply chains and decisive political action. The aim must be to supply Europe with protective material independently and competitively, both now and in the long term.

“We need a strategic production reserve for medical protective clothing in Europe,” said Bernd Reifenhäuser, CEO of the Reifenhäuser Group. “We have to quickly build up the machine capacity for the industrial production of masks in high volumes, but at the same time, the corresponding capacities for the production of the necessary high-quality nonwovens in Europe must be created.”

Cummins, DuPont working on alternative material for N95 respirator masks

As the COVID-19 pandemic spreads across the globe, Cummins Inc. and DuPont are helping address the nation’s shortage of N95 respirator masks. Cummins’ NanoNet® and NanoForce® Media technology, which uses DuPont’s Hybrid Membrane Technology (HMT), can typically be found in air, fuel and lube filtration products used in heavy-duty diesel engines to prevent long-term engine wear, but also can be used in the N95 respirator masks worn by healthcare professionals to filter harmful airborne particles that can spread COVID-19.

The need for N95 masks has skyrocketed in recent weeks in response to the COVID-19 pandemic. Many of the world’s leading mask manufacturers are in need of the critical materials to assemble the mask and are struggling to meet demand.

“Cummins is re-evaluating our supply base and manufacturing capabilities to identify how we can support our healthcare professionals who rely on critical personal protective equipment to do their jobs,” said Amy Davis, Vice President of Cummins Filtration. “Our NanoNet® Media can fill a key supply void and help address the mask shortage facing the United States and other countries around the world.”

The first mask prototypes using Cummins’ donated media were assembled by University of Minnesota teams in March as part of an initiative to provide masks to M Health Fairview and other Minneapolis-based healthcare systems. As the COVID-19 outbreak escalated, the University of Minnesota realized their supply of N95 masks to protect healthcare workers would potentially run out in a matter of weeks. To address this challenge, a team of designers, engineers, chemists, surgeons, anesthesiologist and apparel and clothing experts from the University of Minnesota’s Institute for Engineering in Medicine; Medical School; College of Design; College of Science and Engineering; and Center for Filtration Research Consortium (CFR) came together to address this projected shortage of critical personal protective equipment.

“The first thing we recognized from our experts in the Center for Filtration Research, who work directly with Cummins, is that not all filtration materials are created equal and that the Cummins material is an excellent alternative,” said Jakub Tolar, Campus Health Officer and Medical School Dean at the University of Minnesota. “We are tremendously grateful for the generous donation from Cummins of their filtration materials toward our mask effort. Since the arrival of the filtration media, we have been able to make rapid progress, and we now believe we have several viable mask options, including both a disposable and re-usable option. These designs show real promise in keeping our healthcare workers safe should standard medical supplies of N95 masks no longer be available,” continued Tolar.

DuPont’s Hybrid Membrane Technology goes beyond the limits of traditional semi-porous or nonwoven membranes for air and liquid filtration. Made using a proprietary spinning process, the hybrid technology materials are comprised of continuous sub-micron fibers. The end result is a “membrane-like” sheet structure that balances breathability and high filtration efficiency of particulates.

While products featuring Cummins’ media will need to be vetted and approved by the National Institute for Occupational Safety and Health (NIOSH), the company is preparing to do its part to help relieve the burden facing the healthcare industry. “We’re working as quickly as possible with healthcare regulators and other partners to help certify products with our materials, and prepare our manufacturing facilities to meet demand,” said Davis.

Berry contracts with Reifenhäuser Reicofil for new meltblown line in France to produce respirator materials

Reifenhäuser Reicofil and Berry Global Group have signed a contract for a meltblown line to produce filter material for FFP2 (N95) and FFP3 (N99) respirators. The plant is scheduled to be delivered in June. In order to support the fight against the coronavirus, Reifenhäuser Reicofil has reduced the delivery time of the line by one third, to 3.5 months.

The 1.6 m wide Reicofil meltblown line is equipped with a technology for electrostatic charging for filter materials, a key component of face mask filtration. The plant will bring an additional annual capacity of 550 tonnes of N95 material and 365 tonnes of N99 material, respectively. serving the EMEA market.

The plant will be installed in France.

“We are pleased that the Berry Group, the world’s largest producer of nonwovens, is investing in new capacities for urgently needed, high-quality filter material,” said Bernd Kunze, Ph.D., CEO of Reifenhäuser Reicofil. “The demand for these materials is currently enormous and will, in our opinion, remain so in the future. We will provide all producers, who want to get involved in the fight against COVID-19, with the best possible support for rapid project realization.”


NC State’s Nonwovens Institute to employ novel material for production of masks and mask filters

NC State’s Nonwovens Institute (NWI) is using its two research and training pilot production lines to produce face mask materials that will be used to protect medical workers supporting the COVID-19 response.

N95 respirators and surgical masks are generally a sandwich of one or two common nonwoven layers – so-called spunbond layers that provide mask shape and protect the inner filtration layer – combined with a layer of nonwoven meltblown material that serves as the filtration layer and captures microscopic unwanted particles like viruses and bacteria.

But because of the current critical need for masks caused by COVID-19, the NWI team created a new spunbond material that can serve as an effective filter without the need for a meltblown filtration layer. The unique fabric is composed of two different polymer materials that are combined to make a single fiber with significant strength and bulk – and that shows effectiveness in filtration similar to current materials used.

“Because of the COVID-19 crisis, we took the spunbond technology and created a new generation of unique filters that have excellent filtering capability and can potentially be reused after cleaning with peroxide, or potentially alcohol solution,” said Behnam Pourdeyhimi, executive director of NWI, Wilson College of Textiles associate dean for industry research and extension and William A. Klopman Distinguished Professor. “Because these materials are strong, unlike classical meltblown filters, they can also be cut and sewn by traditional techniques.”

Typically, one meter of spunbond material provides enough material for about 20 to 25 masks when using the current designs, Pourdeyhimi said. One of the NWI’s production lines started producing 2,000 meters of spunbond material per hour, with the potential to create some 20,000 meters of spunbond material in a day. NC State is currently in discussion with industrial partners to make masks with the material.

NWI’s other production line is a meltblowing pilot line that will make the classical meltblown material for N95 masks and surgical masks.

“We created a recipe for the production of classical N95 respirator materials and will ship those materials out for industrial partners to convert these into respirators,” Pourdeyhimi said.

The meltblown material takes a bit more time to produce; Pourdeyhimi estimates that his production line can make about 12,000 meters of material in one work shift.

Thanks to support from across the university, Pourdeyhimi says that NC State has ordered machines that will allow the NWI to make surgical masks in its Centennial Campus facilities. Those machines should arrive in the next month.

“We will set these machines up and take our own materials and convert them into masks and provide them to local communities,” Pourdeyhimi said.


NCTO calls on U.S. to abandon 90-day tariff deferral on textile imports

The National Council of Textile Organizations (NCTO), an association representing U.S. textiles from fiber through finished products, issued a statement from NCTO President and CEO Kim Glas today in response to the U.S. administration’s plan to institute a 90-day deferral on MFN tariffs,  as reported by numerous press outlets.

The reported plan being pushed by the importing and retailing industries would defer certain tariffs, including those on finished apparel products. It is an ill-advised policy that will hurt the U.S. textile industry at the very time it is answering the call of the nation to produce medical supplies to battle the coronavirus pandemic.

NCTO has been at the forefront of the efforts to deploy resources, converting production lines to manufacture urgently needed medical supplies like face masks and their textile components,  to address the critical need for personal protective equipment and other medical and sanitation supplies in the fight against the coronavirus.

These unnecessary tariff concessions would benefit importers and retailers at the direct expense of manufacturers on the front lines of the COVID-19 response and send a demoralizing message.

Tariff deferrals would severely exacerbate ramifications for the U.S. economy, manufacturers and workers and open the floodgates for imports.

If the U.S. government makes tariff concessions during this crisis, it will be inviting a virtual tsunami of imports further devastating domestic manufacturing as it attempts to regain its footing.

We urge the administration to abandon any moves to defer tariffs on finished products. It would only serve to allow importers to exploit the current crisis, while dealing a severe blow to U.S. manufacturing and its workers.


How the coronavirus travels through the air

How the coronavirus travels through the air has become one of the most divisive debates in this pandemic.

As the coronavirus pandemic continues, many people are now overthinking things they never used to think about at all. Can you go outside? What if you’re walking downwind of another person? What if you’re stuck waiting at a crosswalk and someone is there? What if you’re going for a run, and another runner is heading toward you, and the sidewalk is narrow? Suddenly, daily mundanities seem to demand strategy.

Blue Box touts HVAC disinfection protocol for minimizing spread of coronavirus

Blue Box Air, LLC, is touting its disinfection protocol for combating the potential threat for the Coronavirus within commercial HVAC systems. The company’s disinfection protocol was developed to address the expected impact that many healthcare and other commercial buildings will be experiencing once as coronavirus.

Blue Box’s patented process for how to clean and disinfect the heat transfer coils within the commercial HVAC system is designed to optimize building energy efficiency and improving indoor air quality. By changing the formulation and developing a new disinfection protocol, Blue Box will focus on regular treatment of the HVAC systems heat transfer coils, which will involve a combination of using enzymes and chlorine dioxide to disinfect the coils.

Blue Box’s new disinfection protocol involves a process of removing existing biofilm deposits using its enzyme treatment formulation, then injecting Chlorine Dioxide through the coils to ensure that no microbial growths are able to survive. Blue Box has begun piloting its new disinfection protocol in New York City and is beginning to roll out its new service throughout the United States, including Los Angeles, San Francisco, Dallas, Miami, Chicago, Atlanta, and Washington DC.


Oerlikon to supply 2-beam meltblown system to Asian manufacturer; opens its testing lab for production of face mask materials

A leading Asian large-scale manufacturer of manmade fibers and polymers has invested in a new Oerlikon Nonwoven meltblown system. The recently signed contract includes a 2-beam system for manufacturing filtration nonwovens – predominantly for medical products such as face masks – with a nominal capacity of up to 1,200 tons of nonwovens a year. The commercial production launch has been scheduled for the fourth quarter of 2020. 

The 2-beam system has an operating width of 1.6 meters and is equipped with the new patented Oerlikon Nonwoven electro-charging unit. Electro-charging the filter nonwovens allows the manufacture of sophisticated EPA- and HEPA-class filter media as well as media that comply with the requirements of N95-, FFP2- and FFP3-class respiratory masks.

The demand for filtration nonwovens for medical applications has risen tremendously across the globe since the outbreak of the coronavirus epidemic, presenting all manufacturers with huge challenges. “We are currently receiving inquiries from all over the world for our system concepts,” said Ingo Mählmann, Ph.D., vice president of sales & marketing for Oerlikon Nonwoven. “To improve the supply situation, we have changed our prioritization in favor of considerably shorter delivery times for meltblown systems, so that customers can now be supplied even faster and also with very short lead times.”

A meltblown system will be commissioning at the site of a leading Western European nonwovens producers as early as the second quarter of 2020. This system will be deployed exclusively in the manufacture of nonwovens for respiratory masks.

 Due to the current state of emergency with regards to the local supply of face masks, Oerlikon Nonwoven is currently using its own laboratory system to produce electrostatically charged filter media, which are being sent to local small businesses and companies for the manufacture of face masks. “We are thrilled to be making a contribution towards fighting the pandemic, particularly in the local vicinity of our production site in Neumünster”, adds Rainer Straub, head of Oerlikon Nonwoven.

The opportunity to support the fight against COVID-19 accelerated our decision,” said Cedric Ballay executive vice president and general manager for Europe in Health, Hygiene, and Specialties for Berry. “Our ability to be agile will benefit our customers and our communities.”


WPT Nonwovens acquires two lines, readies facility to begin production of surgical & N95 masks

WPT Nonwovens (Beaver Dam, KY) announced it will begin production of surgical masks and N-95 respirator masks, responding to requests from state and local officials looking for Kentucky manufacturers willing to assist with the production of supplies needed for the COVID 19 response.

According to Travis Robbins, WPT Nonwovens Vice President and General Manager, the company has moved forward with the purchase of two fully-automated machines, one for producing surgical masks and one for producing N-95 respirators. It has dedicated 5,000 square feet of its Beaver Dam facility to set up these two new production lines. However, the company said the raw materials needed to produce the masks has been challenging with price gouging on raw materials required to make the N-95 respirators.

Through the supply chain relationships developed by WPT Nonwovens, the company was able to source the necessary materials from a reliable and reputable supplier at an affordable cost. Robbins says that he is confident WPT Nonwovens will be able to supply needs at a price well below what the current market can offer, and that the company will be positioned to run 24/7 production to meet volume demands.

WPT Nonwovens expects to produce 100,000 surgical masks per day, and 35,000 N-95 mask per day. It expects the surgical masks will be ready to ship by May 1, and the N-95 masks will be ready by June 1.

How 3M Plans to Make More Than a Billion Masks By End of Year

Andrew Rehder, manager of 3M Co.’s respirator mask factory in Aberdeen, S.D., got the call from headquarters on Tuesday, Jan. 21. He gathered about 20 managers and supervisors into a conference room, where they sat, unworried, less than 6 feet apart. Rehder told them that a new virus was spreading rapidly in China and that 3M was expecting demand for protective gear to jump.

The Aberdeen plant had already ramped up production of respirator masks in response to demand from first responders battling wildfires in Australia and contending with a volcano in the Philippines. Now, Rehder told his charges, Aberdeen would shift to “surge capacity.” Idle machinery installed for precisely this purpose would be activated, and many of the plant’s 650 employees would immediately start working overtime. “We knew it wouldn’t be a two-week blip, it would be longer,” Rehder says. “But I had no idea.”

This is 3M’s moment, one for which the staid, 118-year-old Minnesota manufacturing giant—the maker of Post-its, Scotch tape, touchscreen displays, and scores of other products—has been preparing for almost two decades.

Honeywell increases production of N95 face masks to support COVID-19 response

Honeywell is ramping up production of N95 masks in the United States to support the COVID-19 response. The production boost will come from the Honeywell factory in Smithfield, Rhode Island, which also produces UVEX safety glasses.

The N95 face masks will be delivered to the U.S. Department of Health and Human Services for use to support health, safety and emergency response workers.

Honeywell expects the new mask production line in Smithfield will create at least 500 jobs. Recruiting, hiring and training manufacturing workers will begin immediately.


Klopman commits to produce 700k face masks per month

Klopman, a European manufacturer of protective fabrics, has committed to produce up to 700,000 protective masks per month, which are sterilizable and reusable up to 50 times, according to the company. Due to its capability in the production of fabrics for the medical and health sectors, the company has been included in Italy’s list of “essential” organizations.

The masks will be made from a double layer of fabric to ensure maximum protection and comfort while in contact with the nose and mouth. A first batch of 10,000 masks will be donated to the health authority of Frosinone and to the hospital “Fabrizio Spaziani,” with a rapid response supply chain in place to serve the needs of public and private operators.

In order to ensure a barrier effect with low particle release, Klopman said its masks will be based on the Vectron 8200 fabric, which is usually used in electronics, cleanrooms and in hospitals due to its characteristics, including a hydro/oil repellent finish to enable domestic and industrial washing at 75°C.


Reifenhäuser Reicofil converts its own meltblown test lines to facemask production

The German machinery and plant manufacturer Reifenhäuser Reicofil has temporarily converted two of its test plants to full production in response to the coronavirus pandemic. The lines installed in the company’s nonwovens technology center, which are otherwise exclusively used for research and development as well as customer trials, have been producing meltblown material for the production of urgently needed facemasks.

Until further notice, the meltblown lines will be operated in 4-shift operation 24/7. The daily output is sufficient for up to one million facemasks. Reifenhäuser said trial operations will be almost completely suspended during this period.

The meltblown material from the nonwoven technology center is already sold out for the next five weeks. However, Reifenhäuser continues to look for opportunities to strengthen the local supply during this crisis. The company is in close contact with associations, authorities and other companies. Material for other medical protective clothing could also be produced at short notice, according to Reifenhäuser.

In related news, Reifenhäuser Reicofil is shortening the delivery time for meltblown lines to 3.5 months, with the aim of supporting the production of the crucial middle material layer for face masks. Supplies of face masks have been severely stressed in the face of the COVID-19 response.

Dr. Bernd Kunze, CEO of Reifenhäuser Reicofil, said, “In situations like the current one, we gladly depart from customary procedures. Sticking to standards in a non-standard situation is out of place. It goes without saying that we will do everything in our power to serve the needs quickly and in the accustomed high quality.”

The first contract with the new delivery time has already been concluded. The 1.6 meter wide Reicofil Meltblown line is scheduled to start operation in August 2020. With an annual output of 550 metric tons, the plant will produce H99 filter material for up to 1.8 million face masks a day.

USTR requests input on lifting ‘Section 301’ duties on Chinese imports of medical-care products

In order to facilitate the U.S. response to COVID-19, the Office of the U.S. Trade Representative (USTR) has announced that it is now accepting comments from interested parties on the possibility of removing some of the additional “Section 301” duties that have been applied on various Chinese imported medical-care products.

According to USTR, each submission must specifically identify the particular product of concern and explain precisely how the product relates to the response to the COVID-19 outbreak. For example, the comment may address whether a product is directly used to treat COVID-19 or to limit the outbreak, and/or whether the product is used in the production of needed medical-care products. Comments may be submitted regarding any product covered by the action in the investigation, regardless of whether the product is subject to a pending or denied exclusion request. However, submissions are limited to comments on products subject to the tariff actions and relevant to the medical response to the coronavirus.

BYD opens face mask and bottled disinfectant plant

BYD created what it describes as the world’s largest mass-produced face masks plant, which is running at full capacity and is able to produce 5 million masks and 300,000 bottles of disinfectants per day. This allows the firm to help alleviate severe shortages that have affected hospitals and agencies across China in the face of the global COVID-19 outbreak.

On February 8, the newly-built production lines in one of BYD’s industrial parks in Shenzhen started to produce these critical supplies, with hundreds of staff working both day and night shifts along with machines working around the clock.

In late January, BYD began to assist in the production of masks and disinfection gels to tackle the growing COVID-19 outbreak. A special task force was appointed by BYD chairman and president Wang Chuanfu, consisting of leaders from different business divisions and more than 3,000 engineers involved in research and development, design, processing and other roles.

The task force moved in less than two weeks to finish work that normally takes two months, completing both the R&D and manufacturing process of mask production equipment within seven days, with the completion of R&D for medical-grade hand sanitizers in six days. Supplies were shipped to medical staff dealing with the COVID-19 response in China.


EU takes action to procure ventilators, masks and medical equipment

European Parliament is working with member states to ensure that the EU can buy ventilators, masks and other medical equipment to be put at the disposal of hospitals across the EU.

Last week, the Commission set up a scheme to gather medical equipment (through rescEU) so that the necessary supplies to combat COVID-19 can quickly get to member states facing shortages of equipment. This equipment is needed to treat infected patients, protect health care workers and help slow down the spread of the virus.

Parliament is working with member states to swiftly approve 40 out of 50 million EUR for intensive care medical equipment such as ventilators and personal protective equipment, such as reusable masks.

Member states are also joining forces under the Joint Procurement Agreement to buy personal protective equipment, respiratory ventilators and items necessary for coronavirus testing. Working together in this way will give them a stronger position on the world market.


Textile and apparel brands to build supply chain for emergency manufacturing of medical facemasks

American apparel brands and textile companies are responding to a White House request for medical supplies, building a supply chain to fast-track the manufacturing of medical face masks.

Parkdale Inc.– the largest yarn spinner in the U.S. headquartered in North Carolina—helped lead the effort to build the coalition with Hanesbrands, Fruit of the Loom and six other companies to set up a manufacturing supply chain and begin ramping up production of the masks.

The coalition consists of Hanesbrands and Fruit of the Loom, often competitors in the marketplace, who are banding together for the greater good of a nation facing one if its most monumental challenges.

American Giant, Los Angeles Apparel, AST Sportswear, Sanmar, America Knits, Beverly Knits and Riegel Linen are also part of the coalition working tirelessly to respond to a national emergency in the nation’s time of need.

Dr. Peter Navarro, assistant to the President and director of the White House Office of  Trade and Manufacturing Policy, worked with the coalition and helped expedite the production of these masks. The first face masks have been approved by the U.S. Department of Health and Human Services.

The companies expect to begin production on Monday and will make the first deliveries by mid-week.

U.S. Textile and Nonwoven Associations Urge Government to Deem Manufacturing Facilities “Essential”

U.S. textile and nonwoven associations issued a joint statement today urging federal, state and local governments to deem textile and nonwoven manufacturing facilities as “essential” when drafting “Shelter in Place” orders in response to the COVID-19 crisis. The statement was sponsored by the National Council of Textile Organizations (NCTO), INDA (Association of the Nonwoven Fabrics Industry) and Industrial Fabrics Association International (IFAI).

Our associations recognize the serious challenges our elected officials, health administrators and others are facing when issuing orders to protect communities across the country and we understand the necessity for leaders to enforce a ‘Shelter in Place” order or quarantine orders.

Our members make a broad range of inputs and finished products used in an array of personal protective equipment (PPE) and medical nonwoven/textile supplies, including surgical gowns, face masks, antibacterial wipes, lab coats, blood pressure cuffs, cotton swabs and hazmat suits. These items are vital to the government’s effort to ramp up emergency production of these critical supplies.

If workers who produce these goods are not granted an “essential” exemption from “Shelter in Place” and other quarantine orders to go to their manufacturing and distribution facilities, it will cause major disruptions in the availability of these goods. This will create significant hardship to healthcare providers and consumers across the country who depend on steady and stable supplies of these critical items.

We are asking the administration and state and local authorities to provide greater certainty and clarity for our companies and employees and ask for a clear exclusion of our manufacturing operations from “Shelter in Place” orders as the textile and nonwoven products that we make in the U.S. play an essential role in mitigating the shortages of critical supplies. Such a designation will help us avoid disruptions of vital goods and services during this challenging time.


COVID-19 Has Caused A Shortage Of Face Masks. But They’re Surprisingly Hard To Make

Both the masks made for medical personnel and for consumer purchase require a once-obscure material called melt-blown fabric. It’s an extremely fine mesh of synthetic polymer fibers that forms the critical inner filtration layer of a mask, allowing the wearer to breath while reducing the inflow of possible infectious particles.

“We’re talking about fibers where one filament has a diameter of less than one micron, so we are in the nano area,” said Markus Müller, the sales director at German company Reicofil, a major provider of melt-blown machine lines.

And there’s now a global shortage of melt-blown fabric due to the increased demand for masks — and the difficulty in producing this material.

US mulls using sweeping powers to ramp up production of coronavirus protective gear

The Trump administration is considering invoking special powers to rapidly expand domestic manufacturing of protective masks and clothing to combat the coronavirus in the U.S., two officials told Reuters. The biggest producers of face masks in the United States include 3M Corp and Honeywell International Inc.

Health and Human Services (HHS) Secretary Alex Azar said at a congressional hearing on Wednesday that China controls “a lot of the raw materials as well as the manufacturing capacity” related to face masks. Very little of this stuff is apparently made in the (United) States, so if we’re down to domestic capability to produce, it could get tough,” the DHS official told Reuters.


3M ramps up N95 respirator production as demand surges from global coronavirus outbreak
