The Importance of Antibacterial Fiber
The antibacterial fiber can kill or inhibit microorganisms such as bacteria, fungi and viruses. Its purpose is not only to prevent textiles from being contaminated and damaged by microorganisms, but more importantly, to prevent infectious diseases, ensure human health and comfort, reduce the cross-infection rate in the public environment and enable textiles to obtain new health care functions. Antibacterial fiber has a wide range of applications, including home textiles, personal services, sanitary products, health care and special equipment. The research and development of the antibacterial function of textiles is extremely important.
Accelerate Research and Use of Graphene in Antibacterial Fiber
Antibacterial fibers are roughly divided into natural antibacterial and artificial antibacterial. Natural antibacterial fiber itself has antibacterial function, including chitosan fiber, bamboo fiber and hemp fiber. Antibacterial agents need to be added into artificial antibacterial fibers to achieve antibacterial function. Studies have shown that graphene oxide (GO) has antibacterial effects. Compared with traditional antibacterial agents, graphene and its derivatives are not only a potential non-resistant physical antibiotic with low biological toxicity, but also a good carrier for antibacterial active substances. There are currently three theoretical explanations for the antibacterial mechanism of graphene and its derivatives: mechanical damage theory, oxidative stress theory and phospholipid extraction theory.

Alfa Chemistry provides specific technical solutions to develop graphene antibacterial fibers by combining graphene materials with fiber materials. We select materials based on the characteristics of graphene itself, then modify and compound it through specific technical routes to fully reflect the antibacterial properties of graphene in fiber materials. The relevant series of products developed by Alfa Chemistry have significant antibacterial effects, which are significantly better than the performance of products in the same industry. Graphene does not fall off easily from the substrate once attached. There is no obvious change in the macroscopic morphology of the fiber after multiple washings and no significant degradation in performance.
What Can We Do?
