Standard for the detection of antibacterial and anti - mite fabrics

[Antibacterial anti mite fabrics] performance testing and standards: polyester antibacterial anti-mite fabrics and nylon antibacterial fabric has a special quality testing indicators, that is, antibacterial efficacy, the determination of the effectiveness of antibacterial, domestic and foreign scholars have put forward a variety of evaluation experiments, But there are some shortcomings, the scope of application has some limitations, antibacterial agents can be broadly divided into dissolution type (antibacterial agent in the water can be slowly dissolved in water) and non-dissolution type (antibacterial agent and fiber combination, can not be dissolved) two , The corresponding representative of the antimicrobial properties test methods are: GB15979-2002 disposable hygiene products health standards, also known as "oscillation flask method" for non-dissolution of antibacterial agent production of textiles.



This test will be tested [antibacterial anti-mite fabric] antibacterial rate.


 

(1) polyester antibacterial anti-mite fabrics and nylon antibacterial fabric test principle

Oscillating flask method is a certain concentration of bacteria inoculated on the sample, through a long period of intense oscillation to increase the antimicrobial test and test bacteria contact, compare the number of colonies before and after the change in the number of samples to evaluate the performance of antibacterial fabrics.


 

(2) polyester antibacterial anti-mite fabrics and nylon antibacterial fabric evaluation criteria

According to GB 15979-2002, the difference between the antimicrobial rate of the tested group and the antibacterial rate of the control group was more than 26%, which could be judged by the antibacterial effect of the product. Through the experimental test and analysis, it was shown that the antibacterial polyester fabric Antibacterial fabrics have a good antibacterial effect, the fabric content of antibacterial fabric on the antibacterial effect of the fabric has a great impact on the fabric per percentage of fiber content in terms of antibacterial rate, the fabric has a good antibacterial effect, and antibacterial polyester The fabric has a closer antibacterial effect.





(3) polyester antibacterial anti-mite fabrics and nylon antibacterial fabric test results

Anti-mite performance test results: The test results show that anti-mite antibacterial fabric dust mite, leather mites, chigger mites repellent rate of more than 99%. Antibacterial spectrum determination results: the results show that anti-mite antibacterial finishing fabric can completely kill gold Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus, Streptococcus, Streptococcus pneumoniae, Meningococcal, Neisseria gonorrhoeae, Escherichia coli, Shigella, Salmonella typhimurium, Pneumocystis aeruginosa, Bacillus subtilis, Bacillus subtilis , Gypsum-like Trichophyton mentagrophytes, Candida albicans, Penicillium, Aspergillus niger and other harmful bacteria.



[Antimicrobial anti-mite fabric] principle:

Anti-bacterial mite fabrics have good safety, it can be completely and completely remove the bacteria on the fabric, fungi and mold, to keep the fabric clean, and to prevent bacterial regeneration and reproduction. Antibacterial fabric injection at high temperatures on the polyester and nylon fiber , Antimicrobial fabric injection is fixed in the fiber and is protected by fiber, so it has a washable and reliable broad-spectrum antibacterial effect of its antibacterial principle is that it destroys the bacterial cell wall, because the intracellular osmotic pressure is extracellular osmotic pressure 20-30 times, so the cell membrane rupture, cytoplasm leakage, which also terminated the microbial metabolic process, so that micro-organisms can not grow and reproduce.
