ISO 18184:2019

Textiles — Determination of antiviral activity of textile products



Feline corona virus, Strain Munich



This document specifies testing methods for the determination of the antiviral activity of the textile products against specified viruses. Due to the individual sensitivities, the results of one test virus cannot be transposed to other types of viruses. Si-Quat is tested with a Corona Virus.

The textile products include woven and knitted fabrics, fibres, yarns, braids, etc.

Si-Quat has preformed at 10log 1.8 translating to over 95%in 20 min. This means the sample has 95% less pathogens recorded compared to the control group.

The ISO 18184 test standard is designed to exam the ability of fabrics and other comparable materials to kill virus.  Standard virus contact times range from 2 hours to less than 24 hours.  Different viruses may have inherent sensitivity to the underlying material, so a control group is also included into the test to determine the antiviral effects of the treated textile over any inherent antiviral performance of the test substance. The recorded 10 Log reduction is the comparable reduction between control and treated textile.


ISO 18184 is a textile surface test generally used with the different viruses that can be replaced by others, in the case of Si-Quat this would be focused on Sars-Cov-2 for the moment the fabrics have been tested with a corona virus. Due to the nature of the mechanical kill of the Si-Quat, and the proof gathered with the ISO 21702 standard on Sars-Cov-2 we are safe to say the Sars-Cov-2 pathogen will react the same to our active ingredient.

Testing the Anti-Viral efficacy could depend on the type of fabric.

To mimic a more real life scenario Si-Quat has been tested and passed an altered ISO 18184 conducted after 20 minutes.  This was the fastest time measurement that could be taken by our lab partners.

Si-Quat Antimicrobial textiles meet the requirements of ISO 18184.

Washing testing when combined with ISO 18184 or another antimicrobial test can provide important data on how a material will perform after exposure to conditions found in its intended use environment. Our products have been tested up to 50 washes.

Si-Quat Mask (Grey - v2 - Scale)-07.png

At AFFIX Labs we have chosen not to make claims on filtration reduction of our masks. For optimal filtration you should wear a medical mask. 

We aim our Si-Quat technology on the fact that people are misusing their masks. touching the face side and contaminating their hands. Putting masks in their pockets etc. We do not make a medical claim.
