Textile treatment effective against corona virus

HeiQ Materials AG

Catalyzed to action by the global fight against corona virus, the supplier of finishing technology, HeiQ Materials AG, Zurich/Switzerland, has launched HeiQ Viroblock NPJ03, an antiviral and antimicrobial textile treatment which has proven effective against human coronavirus in face mask testing.

It significantly enhances the antiviral log reduction from 2.90 of untreated face masks to 4.48, over 99.99% reduction of virus infectivity (a log reduction of 2 is equivalent to 100 times the effectiveness).
The 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. HeiQ Viroblock NPJ03 is a unique combination of vesicle and silver technologies designed to inhibit the growth and persistence of bacteria and viruses. The vesicle technology targets lipid-enveloped viruses, e.g. coronavirus, providing rapid virus deactivation, while the silver technology inhibits the replication of both bacteria and viruses.
Besides testing on human corona virus, HeiQ Viroblock NPJ03 also demonstrates improved reduction of virus infectivity against Influenza types H1N1, H5N1, H7N9, and Respiratory Syncytial Virus (RSV).
Treated masks will be available on the market as early as this April. HeiQ Viroblock NPJ03 can be applied to a wide spectrum of textile surfaces including face masks, air filters, medical gowns, curtains, drapes and more. A range of international textile producers are evaluating the technology on other types of textiles such as cotton and polyester fabric used for garments. HeiQ also has a range of highly wash-durable antimicrobial and odor control textile technologies, called HeiQ Pure, combining silver-based and bio-based materials for all fabric types.
