Swiss based company HeiQ is a leader in textile innovation, creating some of the most effective, durable and high-performing textile technology in the market today.

Did you know textiles and clothing can provide a large surface for viruses and bacteria? These germs can remain active for days and be spread or transferred to other surfaces. HeiQ’s new technology HeiQ Viroblock is designed to inhibit the presence and growth of bacteria and enveloped viruses, such as coronavirus and influenza, on textile surfaces.
So, how does it work?
HeiQ Viroblock is an intelligent Swiss textile technology that is added to fabric during the final stage of the manufacturing process. It uses a unique combination of silver and vesicle technologies in a dual defence against dangerous pathogens:

The HeiQ vesicle technology - many viruses are coated by a lipid (fatty) membrane that protects them. HeiQ vesicle technology targets the membrane surrounding the virus. This exposes the virus, deactivating and making it useless within minutes.

HeiQ silver technology - inhibits the replication of bacteria and deactivates viruses.

Tested by Microbe Investigations AG (mis), AVIRO fabric treated with HeiQ Viroblock NPJ03 shows initially very good antimicrobial activity with 99.69% reduction. With good antimicrobial activity after x15 washes (99.29% reduction). AVIRO has also passed HeiQ’s qualitative antibacterial activity certification (hydrophilic fabrics).

We are committed to supplying safe and effective products to our consumers. To ensure the efficacy of the antiviral component we have completed our own independent ISO18184 antiviral testing and achieved a 99.29% against Influenza H1N1 ATCC VR-1683, Coronavirus (feline), Strain Munich.
HeiQ Viroblock
The antiviral efficacy of HeiQ Viroblock has been proved with an extensive series of Good Laboratory Practice (GLP) Tests performed by accredited Microbiotest (a division of Microbac Laboratories) against a broad set of viruses.

HeiQ Viroblock is among the first textile technologies in the world to be proven effective against SARS-CoV-2 in the laboratory. SARS-CoV-2 is the enveloped virus that causes COVID-19. Tests have been conducted by HeiQ with the Peter Doherty Institute for Infection and Immunity in Melbourne, Australia. Showed that treated fabric achieved 99.99% reduction of the virus.

HeiQ Viroblock has also been tested against Influenza types H1N1, H5N1, H7N9, and Respiratory Syncytial Virus (RSV) and demonstrated significantly improved reduction of virus infectivity.
