Testing the antiviral activity of textiles

Testing the antiviral activity of textiles

(ISO 18184 -Determination of Antiviral Activity of Textile Products)

In recent years, an increasing number of products in the textile industry have been developed with protective effects for health and hygiene. These antiviral textile products are fabrics, which can reduce the number of infective virus particles that can survive on its surface.

Our experienced team can help determine the antiviral activity of your textile products by performing the ISO 18184 test. This standard provides a quantitative method to assess the antiviral performance of textile products. Suitable materials for this test include woven and knitted fabrics, fibres, yarns, braids etc. Very thick or absorbent products (such as carpets, which cannot be removed from the backing) may not be suitable for testing by this method. Please speak to us to discuss alternative methods that can be used.

The method of testing the antiviral activity of textiles involves placing and incubating a small amount of virus on the treated and untreated fabric for a specific contact time, according to ISO 18184 procedures. At the end of the test, the amount of virus surviving on the treated and untreated control fabric is counted and the reduction rate is calculated. This is expressed as a percentage reduction on the test report.

This test data can then be used to report the specific antiviral activity of a product (labelled ISO 18184). This test is readily available for the following viruses: feline coronavirus, Influenza H3N2, Influenza H1N1, Feline Calicivirus, and Vaccinia virus (other viruses may be available on request).

The booking process is incredibly straightforward. Simply choose the date you would like to receive your report and send us your sample textiles within seven days of reserving this. We will then perform the test and submit your technical report on the agreed date. For more information and to book, click here.
