Antibacterial fabrics that “fly into ordinary people’s homes”

The porous shape of textile fabrics composed of fibers and the chemical structure of high-molecular polymers are conducive to the attachment of microorganisms, making them a good parasite for the survival and reproduction of microorganisms. In addition to contaminating fibers, parasites can also harm the human body. Therefore, the main purpose of antibacterial fabrics is to eliminate these adverse effects.

Antibacterial fabrics have good antibacterial effects, can eliminate odors caused by bacteria, keep fabrics tidy, and avoid bacterial reproduction, which can reduce the risk of re-transmission.

Main applications: socks, underwear, workwear fabrics, outdoor sports fabrics, etc.

At present, there are different standards for antibacterial testing, such as American standards and national standards, which are mainly divided into two categories. One is to monitor specific values, such as antibacterial rate reaching 99.9%; the other is to issue logarithmic values, such as logarithmic values ​​of 2.2, 3.8, etc. Usually when the logarithm value reaches 2.2 or above, the test is qualified. The main strains tested include: Staphylococcus aureus, Escherichia coli, methicillin-resistant Staphylococcus aureus MRSA, Klebsiella pneumoniae, and fungi such as Candida albicans.

Main testing standards: AATCC100, AATCC147 (American standard)

1) AATCC100 is a textile antibacterial performance test (qualitative). This standard is relatively strict. The results of the 24-hour evaluation are evaluated based on the bacterial reduction rate, which is similar to the sterilization standard. The detection methods of Japanese and European standards are basically antibacterial testing, which is an assessment of whether bacteria do not grow or are slightly reduced after 24 hours.

2) AATCC147 is a parallel line measurement method, which detects inhibition zones. This standard is mainly used for organic antibacterial agents. National standard: GB/T 20944, FZ/T73023; Japanese standard: JIS L 1902; European standard; ISO 20743.

Under normal circumstances, once a person’s microbial flora is imbalanced, a small number of bacteria among them will multiply and cause harm to the human body through the skin and respiratory tract. When the human body wears textiles, they will produce a lot of sweat and various human secretions, and they will also be contaminated by dirt in the environment. They will become an important media in the reproduction and transmission of germs, so people need to be able to resist them. Bacterial textiles to meet health requirements.
