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).


It depends on the projected application and on the environment where the textile product is intended to be used. 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: Klebsiella pneumoniae and Staphylococcus aureus
