Testing is required to prove the Antibacterial qualities of a final product textile and support marketing claims or studies. Of course, laboratory testing is not the same as real-world testing. Therefore, they should compare results to real-world outcomes.
In the Antibacterial testing lab, Textiles are tested using a variety of conventional procedures, including but not limited to:
This test is carried out on both treated and untreated test material samples. The test sample is infected with 1 ml of test organism suspension containing roughly 1000,000 CFU/ml, per the AATCC 100 test procedure. Organisms are removed at a specific time using a diluted and plated neutralizer medium.This procedure evaluates the Antibacterial test agent's bacteriostatic and bactericidal properties.The hydrophobic nature of textiles might influence the Antibacterial activity test findings obtained by the AATCC 100 test technique.
This test method is used to determine if specimens treated with a non-leaching Antibacterial agent are resistant to microbe growth under dynamic contact circumstances. It is used to analyze substrate-bound Antibacterials and was developed for regular quality control and screening testing. All samples are shaken in dynamic shake flasks in a wrist action shaker to maintain good contact between the bacteria and the treated fiber, fabric, or other substrates throughout the test time by continual agitation of the test specimen in a bacterial suspension. Antibacterial agents that have been immobilized, such as surface-bound compounds, cannot disperse into their surroundings under normal operating circumstances. During the test time, the test material is constantly agitated in a bacterial solution, ensuring good contact between bacteria and the treated fiber (1hour). Microbial concentrations in treated and untreated samples are generally measured after 0, 1, or 24 hours of contact.
It is dependent on the intended purpose and the environment in which will utilize the textile product. Customers have the option of using one of the following methods to determine antibacterial activity: The bacterial suspension is injected directly onto the samples in the absorption technique. The Adenosine Triphosphate Luminescence technique and the Colony Plate Count method are both described for measuring bacterial enumeration.
