Idvac: antimicrobial properties on fabrics through vacuum metallizing

Vacuum metallizing allows the deposition of materials in a clean, dry environment and can be done at high speed to reduce the cost of the end product. Idvac Ltd., Manchester/UK, specializes in the development of new vacuum processes and products for security and decorative holograms, packaging and solar window film sectors has recently developed a novel process to use vacuum metallizing technique to deposit a thin layer of polymer on flexible substrates such as polyester and fabric. This Idvac polymer coated PET film presented very good antimicrobial properties and the process does not involve any solvent or wet chemicals.
Testing of the antimicrobial properties of this polymer coating was carried out by Gencoa Ltd., Liverpool/UK, using its new Gencoa-Miller testing method. The Gencoa-Miller method has been developed as a new method for evaluating antimicrobial efficacy in order to facilitate the fast research and development of antimicrobial coatings. The test result showed very good properties, >= Log 5 equivalent or about 100% on Gencoa-Miler scale.
Idvac is conducting further biochemical/biomedical investigation of this polymer coating against some viruses and may possibly include Covid-19 virus.
Polyester, cotton fabric or paper filters coated with this polymer could be used to make antimicrobial face masks, hospital bed sheets, air filters and protective clothing for health applications.

Devan/Anker/Shark: flame retardant carpet with recycled PVB based binder

In order to create the world’s first flame retardant aviation carpet using a recycled binder, the supplier of specialty chemicals Devan Chemicals NV, Ronse/Belgium, the specialist in woven carpets Anker Gebr. Schoeller GmbH + Co. KG, Düren/Germany, and the cleantech specialist Shark Solutions, Roskilde/Denmark, a company focused on giving a new life to post-consumer PVB (polyvinyl butyral), have teamed up.
The PVB binder from Shark reuses laminated glass, from windshields and architectural/building glass, that otherwise would go to landfill. Properties of the aviation carpet with PVB as binder are the same as those of traditional non-sustainable carpets. The non-toxic binder (no chlorine or phthalates) is fully recyclable and thus lives up to the future standards of the industry. Devan was called in to develop the flame retardant back coating, which is compliant with the Airbus and Boeing safety standards. The plan is to take out traditional non-sustainable aviation carpets stepwise as soon as possible.
Devan and Anker are already working on a new project, which includes Devan’s antimicrobial/viral-reducing technology. Recently, Devan published test results on the activity of their technology (Bi-Ome) against SARS-CoV-2 (corona virus) and other viruses. According to independent testing, Bi-Ome is proven to achieve 99% and higher virus reduction, including of corona, on samples before washing and retains 98.5% even after 25 wash cycles.

Liquid X: face mask with antimicrobial filter insert

The proprietary, particle-free silver ink of the manufacturer of functional metallic ink, Liquid X, Pittsburgh, PA/USA, used to create e-textiles and other functional textiles has received the Oeko-Tex Standard 100 Certification. Liquid X earned the strictest, baby-safe rating, Appendix 4, Product Class 1, certifying that its particle-free silver ink applied on polyester nonwovens meets the human-ecological requirements. Also an Oeko-Tex-certified face mask, called ComforTex, and a protective SecuriTex antimicrobial filter insert has been launched.
This unique uniform coating capability also helps to create non-electronic textiles, such as protective antimicrobial coatings for medical gowns, hospital curtains, automotive upholstery etc.
Over the past year, Liquid X has been developing new smart textile solutions for multiple industries including automotive, aviation and medical. Because the company’s inks use silver, zinc and copper metals that contain antimicrobial properties, the Covid-19 pandemic prompted Liquid X to begin offering antimicrobial textiles featuring a uniform antimicrobial coating that fights off pathogens from the fabric.

Ascend: Surgical mask in development with Acteev technology

On June 13, 2020, the manufacturer of fiber technologies Ascend Performance Materials, Houston, TX/USA, has submitted to the U.S. Food and Drug Administration a 510(k) premarket notification for clearance to market its Acteev technology in a pair of high-efficacy surgical masks to protect against SARS-CoV-2. The masks, a nanofiber and a microfiber nonwovens version each branded under the Acteev Biodefend line for medical devices, deliver a one-two punch of antiviral properties plus top-level barrier protection against microbes, harmful airborne particles and fluid splatter. Acteev technology has been shown in laboratory tests to deactivate SARS-CoV-2, the coronavirus that causes Covid-19, and other pathogens. The testing was conducted following the protocols of ISO, ASTM or other international standards organizations. Ascend submitted its first 510(k) to the FDA last month. That submittal requests clearance to market a Level I surgical mask that is effective against SARS-CoV-2. Also last month, Ascend launched Acteev Protect, an antimicrobial line of protection specially formulated to guard against the growth of fungi, bacteria and other microbes to keep textiles and nonwovens fresher for longer. Acteev Protect, available for sale in the USA and select other jurisdictions, can beused to make face coverings, filtration devices, and textiles for upholstery and apparel such as activewear.

Rudolf: all-in-one, durable antibacterial and antiviral solution for textiles

As a consequence of Covid-19 global pandemic the demand for chemical auxiliaries with antimicrobial effect has boomed. The producer of textile auxiliaries Rudolf GmbH, Geretsried/Germany, has invested in the assessment of a new antiviral feature which is now added to one of their leading technologies. Such an effort returned the surprisingly fast and most comprehensive antibacterial and antiviral textile finishing Ruco-Bac AGP. The microstructures in Ruco-Bac AGP trigger their powerful antibacterial and antiviral effects based on 3 distinctive inhibiting mechanisms: 1. Blocking of oxygen-transporting enzymes therefore leading to impaired growth. 2. Crushing of disulfide bonds and therefore structure of sulfur-containing proteins. 3. Possible interference with Bacteria and virus surface protein in the membrane. Ruco-Bac AGP effectively protects any textile against bacteria (harmful and odor-causing) and its superior antiviral performance on textiles has been independently demonstrated. Assessments were carried out on enveloped coronaviridae families known to cause a broad spectrum of animal and human diseases. It is suitable for next-to-skin applications and cytotoxicity tests show that it has no influence on the natural microflora of the skin. Furthermore, because of the adhesion mechanism of its microstructures, Ruco-Bac AGP is only active in/on the textile and it is non-migrating.
