There's power
in simplicity

HeiQ Viroblock is an innovative Swiss technology makes fabrics resistant to harmful microbes. It is added to the fabric during the final stage of the textile manufacturing process.

Vira-X brings an easy & effective solution to securing your staff and guests against some of the most challenging pathogens.

Effective in minutes* Lasts for weeks.

  • Strong antimicrobial efficacy demonstrated by ISO 20743 and ISO18184 tests
  • Vira-X can be used for clothing, home textiles and accessories such as face masks and gloves to make them extra resistant to harmful microbes
  • For washable fabrics: the treatment is effective for at 3-5 washes at 30°C
  • Hypoallergenic, provides self-sanitizing and germ resistant surface
  • Patent pending combination of advanced silver and vesicle technology
  • HeiQ is winner of coveted Swiss Technology Award 2020 for HeiQ Viroblock
  • The treatment is EU BPR & EU REACH compliant
  • Main ingredient is registered with US TSCA and US EPA


Virax Viroblock is among the first textile technologies in the world to be proven effective against SARS-CoV-2 by an independent institution*. SARS-CoV-2 is an enveloped virus from the coronavirus family that causes COVID-19. Tests have been conducted by HeiQ with the Peter Doherty Institute for Infection and Immunity in Melbourne, Australia (Doherty Institute).

HeiQ Viroblock is designed to inhibit the growth and persistence of bacteria and enveloped viruses on textile surfaces. It’s a unique combination of our registered silver technology for antiviral and antibacterial effect and our vesicle technology as a booster. * M.J.

  • Small silver particles are potent antimicrobial and anti-viral agents due to high surface area to volume ratio and unique chemical and physical properties [Galdiero 2011]
  • Small silver particles are effective against viruses, effectively eliminating them following short exposure of isolated viruses to silver [Galdiero 2011]
  • Silver interacts with the sulphur-bearing moieties of viruses and can form complexes with electron-donor groups leading to inhibition of post-entry stages of infection through blocking of viral proteins
  • HeiQ small silver particles contribute to a broad spectrum of anti-viral mechanisms that are not prone to inducing resistance
  • The silver stays active for 100 washes at 30°C

A potential host for microbes – Textiles

Textiles provide us with the most basic protection to our bodies, ensuring comfort and well being. But they also provide a large hosting surface for all kinds of microbes, some of them are harmful for the textiles, and these microbes can live for days to months on textiles and multiply rapidly!

Feel safe, clean and hygienic in your clothes, enjoy relaxing time on your fabric sofa and sleep carefree in your bed. HeiQ Viroblock protects the textiles from harmful microbes and germs.

The performance of HeiQ Viroblock has been tested extensively at 3rd party institutes worldwide. See here a selection of  test reports (LINK).
