New Textile Treatment Effective Against Covid-19

Viroblock NPJ03 from HeiQ is effective against the coronavirus

A Swiss textile innovation company has fast-tracked the launch of an antiviral and antimicrobial textile treatment after it proved to be effective against the coronavirus.

The Viroblock NPJ03 from HeiQ uses a combination of vesicle and silver technologies; the former targets lipid-enveloped viruses (such as Covid-19), while the latter inhibits the growth and persistence of bacteria and viruses.

In its in-house tests on face masks, the treatment reduced the virus infectivity by over 99.99%.

As well as masks, the technology can be applied to a wide range of textile surfaces, including air filters, medical gowns and curtains, with single-use non-woven fabrics being a particularly smart application.

“Our goal is to prevent textiles from becoming a host surface for propagating harmful viruses and bacteria – and contribute to reduce the risk and speed of contamination and transmission,” says Carlo Centonze, chief executive of HeiQ Group.

Demonstrating the efforts to urgently address the global pandemic, Chinese protective mask producer Suzhou Bolisi has already adopted Viroblock NPJ03, with treated masks expected to be available as early as April. Other manufacturers are actively evaluating the technology for use on hand protectors and other garments.
