Determination of Antibacterial Activity of Textile Products

ISO 20743: What Does Antibacterial Activity of Textile Products Mean?

What is Antibacterial Activity in Textile Products?

Antibacterial activity is the resistance of a textile product against bacteria. Such properties are often used in textiles to prevent bacterial infections, inhibit odor formation and improve hygienic conditions. Antibacterial textiles are widely preferred, especially in areas such as hospitals, sportswear and underwear.

All products such as antibacterial clothing materials and textiles are offered for sale with claims that they have the ability to kill or reduce harmful bacteria in contact with the fabric material. Antibacterial textile products produced for materials that can be used in special areas are tested with the ISO 20743 standard.

Purpose of ISO 20743 Standard

The ISO 20743 standard provides a test procedure for determining the antibacterial properties of textiles. This procedure is used to determine whether textiles are effective against microorganisms. This test is important to determine antibacterial activity and to assess how long these properties last during production, in use and during washing.

The standard “ISO 20743 - Textiles - Determination of antibacterial activity of textile products” aims to test the ability of fabrics treated with antimicrobial agents to inhibit microbial growth and kill microorganisms.

Microorganisms used in the test procedures within the scope of the standard; S. aureus and K. Pneumoniae

Test Methods within the Scope of the Standard

ISO 20743 standard has different test options according to the intended use of the product to be tested.

Absorption Method: In this method, the test bacterial suspension is inoculated directly into the treated antibacterial sample.
Transfer Method: The transfer method involves inoculating the agar plate with the test bacteria and then transferring it to the processed antibacterial sample. This sample is further incubated for 18-24 hours under humid conditions.
Print Method: In this evaluation method, test bacteria are placed on a filter and printed onto the treated antibacterial sample. The sample is incubated for 1-4 hours under humid conditions.

ISO 20743 standard test methods can be performed on many products such as fabrics, yarns, bedspreads, household items.
