From the Sector

Patients as well as air-condition and ventilator systems spread SARS-CoV-2 virus as aerosols which settle on surfaces and remain there infective for more than 72 hours. That‘s why the pandemic has triggered an intensive search for Personal Protective Equipment PPE whose surfaces have antiviral properties, e.g. are able to bind and inactivate adhering virus.

In this context the chemical stability of the materials being used for PPE, polypropylene PP and/or polyester PET, is a challenge. More precisely, the absence of so-called ‘functional groups‘, like -OH, -COO-, -NH3+ at the material‘s surface. These groups are the fundamental basis for surface chemistry – specifically for attaching antiviral compounds onto the surfaces of man-made fibers.

Antiviral surface modification with the basic amino acid Arginine Arg is a new approach to inactivate SARS-CoV-2. - bionic surfaces‘ - development was tested according to ISO 18184:2019 „Determination of antiviral activity of textile products“ at Institute for Virology and Immunology at University Wuerzburg, Germany. - The finding: „[Six hours] incubation on [Arginine] coated NW reduced viral infectivity by more than five orders of magnitude.“ In other words: An amount of, for example, 10.000.000 virus is reduced to 100 (by five orders of magnitude).

- bionic surfaces – has more than 30 years experience in wet-chemical surface modification of man-made polymers like PDMS, PP, PE, PTFE.

A polybutylene succinate (PBS) polycondensation system was commissioned at Yingkou Kanghui Petrochemical Co. Ltd. in Dalian in the Chinese Liaoning Province at the beginning of January 2021. The PBS system, for which Oerlikon Barmag Huitong Engineering supplied both equipment and engineering, has a daily production capacity of 100 tons

It is used to manufacture high-viscosity chips for biodegradable films. Consequently, Yingkou Kanghui, a subsidiary of the Hengli Group, is catering to rising demand for biodegradable polymer products – demand that is increasing not just in China, but across the globe. Yingkou Kanghui Petrochemical Co., Ltd., founded in 2011, predominantly produces polyester chips and films. By expanding its portfolio to include the manufacture of PBS products, the enterprise is positioning itself as a pioneer of biopolymer production: In view of the large quantities of plastic waste not just in the oceans, biopolymers are considered the materials of the future.

Belgian textile innovator Devan Chemicals was lauded by Frost & Sullivan for its antimicrobial technology with proven quaternized silane chemistry, known under its trade name as BI-OME®.

RONSE, BELGIUM – The non-leaching attributes of the technology coupled with its ability to reduce microbial mutation make it a potential candidate for textiles where durability and safe human contact are highly valued.

Based on its recent analysis of the European antimicrobial technology for the textile market, Frost & Sullivan recognizes the Belgium-headquartered Devan Chemicals NV (Devan) with the 2020 European Technology Innovation Leadership Award. Devan’s highly relevant antimicrobial technology addresses issues concerning the contamination of PPE and textiles, including the spread of drug-resistant bacteria, viral transmissions, and hospital-acquired infections (HAIs). Its quat-silane technology, due to its non-migrating behaviour, physically punctures the microorganism cell to destroy it without interfering with cell DNA. Notably, it eliminates the adverse effects of leaching antimicrobials while providing high efficiency in the range of 99.9 percent to 99.99 percent, even after multiple washes.

"By providing non-migrating antimicrobial technology for the textile industry, Devan plugs the safety and performance gaps inherent in current inorganic and organic antimicrobial agents. Its antimicrobial technology, unlike silver- or triclosan-based technology, comprises non-migrating monomers and prepolymers such as organo-functional silane," said Monami Dey, Industry Manager, Frost & Sullivan. "The organo-silane polymers are covalently bonded and polymerized to the textile surface as a coating via padding, exhaust, and spraying techniques. The coating forms a non-leaching reactive surface and destroys the microbes on contact, without releasing harmful components into the environment."

Devan CEO Sven Ghyselinck is very happy with the award: “The best practice award is a nice recognition of the hard work we did in the last 6 months to evaluate the performance against viral activity. It’s great to see our efforts didn’t go unnoticed.”

Earlier this month Devan published new test results confirming the high performance virus-reducing capabilities of its BI-OME fabric coating technology on both unwashed and intensely washed fabrics. The Belgian company has worked closely with a series of international third party laboratories to test different fabric substrates against a wide range of enveloped viruses. Before washing, samples treated with Devan BI-OME score very good to excellent (99% and higher according to ISO 18184) results on virus reduction. Different substrates, like polyester, cotton and polycottons, were exposed to enveloped viruses like SARS-COV-2 (known to cause COVID-19), Feline Corona, Vaccinia (the EU standard for enveloped viruses) and Porcine Respiratory viruses. After 30minutes, BI-OME already reduced 99.96% of the activity of SARS-COV-2.

After washing, a decrease in virus reduction performance of coating technologies is normal and expected. However, BI-OME is confirmed to deliver only a minimal reduction, retaining up to 98.5% virus reduction even when the fabric is washed 25 times.

"Devan is working towards sustainability and green chemistry. For instance, its technology does not contain any harmful solvents such as formaldehyde or polychlorinated phenols and fulfills the regulatory obligations of the EU BPR," noted Dey. "Its commitment to promoting sustainability in textile finishes with a strong focus on GMO-free, kosher, as well as halal certifications, and recyclability has given the company an edge in launching new products at an accelerated pace to match customers’ most pressing concerns and demands."

One of those innovations is BI-OME NTL (natural), a natural, bio-based antimicrobial solution that guarantees an optimal freshness and hygiene for textiles. The active ingredient is the well-known Linseed oil, obtained from the dried, ripened seeds of the flax plant. The active ingredients in BI-OME NTL are GMO free, Halal, Kosher and recyclable.

• World’s largest viscose producer well on track for all of its five mills to be EU-BAT compliant by 2023

Two more Sateri mills in China, Sateri Jiujiang and Sateri Jiangxi, have received verification of compliance to the emissions limits set out in the European Union Best Available Techniques Reference Document (EU-BAT BREF) on Polymers. This brings the total number of EU-BAT compliant mills to three of five, accounting for over 60 per cent of Sateri’s overall fibre production capacity. In April this year, Sateri Fujian was the company’s first mill to be verified as being EU-BAT compliant. Verified by independent consultant Sustainable Textile Solutions (STS), a division of BluWin Limited (UK), the parameters of the EU-BAT BREF assessed included resource utility efficiency, wastewater discharge and air emission. As a highlight, STS’ assessment concluded that the energy intensity and air emission of Sateri Jiujiang and Sateri Jiangxi were well under EU-BAT norms for viscose production. Considering the EU-BAT energy requirements limit of 30GJ/MTf, the mills were each saving about 1,100 kg CO2/MT of fibre production.

The mills also followed local requirements for controlling ecological impact for viscose production, and there were no gaps identified against EU-BAT. Sateri Jiangxi is a 16-year-old mill and the company’s first and oldest, while Sateri Jiujiang was acquired and expanded in 2015. Said Allen Zhang, President of Sateri, “For three of our five mills to meet the EU-BAT emissions limits in such a short span of time is a testament to our continued investment in best-in-class technologies. This applies to all our mills – regardless of whether they are existing, acquired, or newly constructed ones – as we aim to achieve a high level of sustainability performance across all our operations.”

The company is well on track for its remaining two mills, Sateri Jiangsu and Sateri China which were acquired and newly-built in 2019 respectively, to comply with EU-BAT’s recommended emission levels by 2023.

• R&D support for textile odor-management according to international testing standards

To ensure responsible use of biocides and international comparability, test methods and test results for antimicrobial treated products must be transparent, useful and comparable. This is precisely why  SANITIZED AG, the specialist for antimicrobial material protection and hygiene function in textiles and polymers, had its in-house Microbiology Laboratory in the SANITIZED TecCenter certified by IAC, the International Antimicrobial Council. This non-profit, U.S.-based institute aims to increase safety for antimicrobial treated products and for consumers. Textile and polymer product manufacturers value the assistance that the in-house SANITIZED TecCenter provides them with developing and optimizing their products. It supervises technical application aspects, and conducts microbiological tests and analytics—all from a single source. SANITIZED provides specific assistance with the textile manufacturer's R&D work, particularly for the demanding challenge of developing the best possible odor-management for textiles. Now the TecCenter has been certified by the IAC and is a designated “International Antimicrobial Council Certified Laboratory.”

Thanks to the IAC Certification, SANITIZED AG now offers innovation expertise according to international standards that are also recognized and valued in the U.S. and Asia.

“In addition to assistance with product development and product optimization from our TecCenter, SANITIZED customers receive certification of the antimicrobial treatment of their products from an independent organization, the IAC,” explains Erich Rohrbach, Head of Microbiology at SANITIZED AG. “This is an important building block for production chain transparency in the textile industry, which is demanded by a growing number of manufacturers and brands that are driven by end customer requirements,” adds Erich Rohrbach. Many SANITIZED customers particularly value the TecCenter for their development work in odor-management for textiles. SANITIZED offers an innovative product portfolio to meet this demand also including non-biocide additives.

Tests conducted by independent laboratories have now confirmed that a treatment with Sanitized® T 99-19 and Sanitized® T 11-15 reduces the viral load on PES textiles by up to 99 %.

Swiss company SANITIZED AG celebrates validation from impartial labs that Sanitized®T 99-19 and Sanitized®T 11-15 are also effective against viruses (in accordance with ISO 18184:2019).
Tests were performed using a feline coronavirus with structures and mechanisms reminiscent of SARS-Cov2.

Patented technology featuring an ammonium silicate compound is employed in Sanitized®T 99-19 and Sanitized®T 11-15 utilizes tried and tested silver technology. These additives are the perfect tool for an antiviral and antibacterial treatment of face masks, protective professional medical clothing, bed linens, or mattresses.
The formulation of both products remains completely untouched, thus ensuring that it will continue to offer outstanding protection against bacteria.

Before a final product’s antiviral properties can be publicly promoted, viral tests must be performed in specialized laboratories. Compliance with local legal regulations is essential here. SANITIZED AG explicitly points out that this is standard procedure and has composed a preliminary Guide for Treating PPE

SANITIZED AG has been supporting the work of hygienists in hospitals, doctor’s offices, nursing and care facilities for many years with its antimicrobial - and now also antiviral - additives used to enhance the
functionality of textiles and polymers. The reduction of bacteria and viruses is a feasible way to help stem the spread of infections including MRSA.

The Oerlikon Nonwoven experts will be presenting efficient solutions and comprehensive technology know-how for challenging filtration tasks to an international trade audience at the FiltXPO 2020 in Chicago, USA (Stand # 420), taking place between February 26 and 28.

Meltblown technology is one of the most efficient methods for producing very fine and highly-separating filter media made from manmade fibers. New, unique and highly-sophisticated filter media are easy to manufacture thanks to Oerlikon Nonwoven’s optimized meltblown technology. This process is characterized by its constant melt pressure distribution and consistent dwell time across the entire width of the spinning beam, Furthermore, the novel guidance and distribution of the process air outside the coathanger distributor offered by the Oerlikon Nonwoven technology prevents so-called hotspots, which overall ensures particularly homogeneous nonwoven properties and basis weights even in the case of delicate raw materials.

The Oerlikon Nonwoven charging unit stands out against other concepts currently available on the market. Users can freely choose from a large number of variation possibilities and set the optimum charging method depending on the filter application, allowing the Oerlikon Nonwoven charging unit to also be used for the manufacture of EPA- and HEPA-class filter media.

The new forming section ensures improved nonwoven formation evenness across the entire width, even in the case of high spinning speeds, special polymers and polymer combinations. In addition to this, the newly-designed system also ensures that nonwovens only require minimal edge trimming at the end of the production process. The newly-developed mixedfiber technology enables the combining of various filament cross-sections and polymers, in order to set ideal filtering and pleating performances, for example.
