Israel based nylon 6.6 manufacturer Nilit has received confirmation that fabric made with its Sensil BodyFresh yarn has been proven to reduce viral activity on contact.

Independent testing conducted by Microbe Investigations AG (MIS), a microbiological testing services lab, shows the fabric demonstrated a 99.85% reduction in viral activity when tested according to ISO 18184:2019 criteria against Betacoronavirus 1 (OC43), an enveloped, positive-sense, single-stranded RNA virus.

The additive embedded in the Sensil BodyFresh yarn provides long-lasting protection that does not deteriorate with laundering, indicating that the additive is not washed out of the fabric. 

"We originally developed Sensil BodyFresh with antibacterial and anti-odour properties," says Sagee Aran, head of global marketing at Nilit. "With these proven antiviral test results, our business partners can expand their Sensil BodyFresh product concepts beyond comfort and aesthetics to include enhanced protection and a positive sense of well-being."

Sensil BodyFresh is currently used by apparel brands across all segments such as intimates and underwear, base layer, activewear, and legwear. By inhibiting microbial growth, fabrics stay fresher longer and require fewer launderings. The benefits are built into the yarn and do not wash out or wear off for the life of the fabric, providing sustainable protection that does not pollute waterways, according to the firm.

In addition to these antimicrobial benefits, Sensil BodyFresh is responsibly made at Nilit's water- and energy-optimised facilities and meets the firm's Total Product Sustainability guidelines for long-lasting, high-quality products.

A slew of new solutions have been launched in recent weeks to provide textiles with antiviral and antibacterial properties. Among them are HeiQ's Viroblock NPJ03, which is said to reduce 99.99% of human coronavirus SARS-CoV-2, the virus that causes Covid-19, and an anti-viral zipper developed by YKK and Polygiene.
