Determination of Antibacterial Activity of Antibacterial
Finished Products (Textiles)
This International Standard (ISO) specifies quantitative test methods to determine the antibacterial activity of antibacterial finished textile products, including nonwovens.
1. This International Standard (ISO) specifies quantitative test methods to determine the antibacterial activity of antibacterial finished textile products, including nonwovens.
2. It is appropriate for all textile products, such as cloth, wadding, thread and material for clothing, home furnishings and various goods independently of the type of antimicrobial agent used (organic or inorganic, natural or artificial) or the method of application (built-in, after-treatment or grafting).
3. It depends on the projected application and on the environment where the textile product is intended to be used.
4. Customers can choose an appropriate method for determination of antimicrobial activity: Absorption method: evaluation method, bacterial suspension is inoculated directly onto samples , The Colony Plate Count method and the Adenosine Triphosphate Luminescence method are also specified for quantifying the bacterial enumeration.
Organisms typically used in this method: Staphylococcus aureus (ATCC 6538P), Klebsiella pneumoniae (ATCC 4352) and Escherichia coli (ATCC 8739)
FAQs
The ISO 20743 is used for ‘quantitative test to determine the antibacterial activity of all antibacterial textile products’, is designed to test the ability of fabrics that have been treated with antimicrobial agents to prevent microbial growth and to kill microorganism .
The exact test method for the ISO 20743 can be found here.
The ISO 20743 takes 3 to 4 days.
Our laboratory can perform the ISO 20743 on 6(bacteria/viruses). Additional strains can be added on request.
