Silver & Vesicle technology

Viroblock technology from Switzerland combines an advanced silver and a vesicle technology to inhibit growth and persistence of microorganisms on the fabric surface. Silver and Vesicle technology resistant to bacteria and viruses. The treated fabric is able to kill virus within minutes. 


Viroblock’s rapid mode of action makes this technology one-of-a-kind to destroy harmful enveloped viruses.

It is a unique combination of HeiQ’s advanced silver technology and a vesicle technology as a booster. Silver emits silver-ions to inhibit bacteria on the fabric surface. The vesicle technology depletes the viral membrane thus silver can work more efficiently and rapidly to attack the core of the virus.

Both tables illustrate the number of days bacteria and viruses could remain active on textile surfaces without food. For example, Staphylococcus aureus , Staphylococcus aureus the clinically relevant bacteria that cause skin infections such as boil, could host themselves on dry inanimate surface and survive from 7 days up to 7 months.

With this unique combination of HeiQ's registered silver technology for antiviral and antibacterial effect and vesicle technology (as a booster), the treated fabric is able to reduce infectivity of various enveloped viruses: 

  • SARS-CoV-2 (the Covid-19 causing virus)

  • H1N1

  • H5N1

  • Influenza A (H3N2) Variant Virus

as well as inhibiting growth of various bacteria strains.
