Chitosan is also called chitin. It is a kind of glucosamine polymer containing cationic glucosamine extracted from crab and shrimp shells through modern high-tech processing. Chitosan is the second largest natural bio-organic resource in nature after cellulose. Known as "the guardian of human immunity", "the sixth vital element necessary for the human body today" and so on.

Chitosan fiber is a polymer prepared by using chitosan as the main raw material, dissolving it in a suitable solvent, formulating it into a certain concentration of colloidal spinning stock solution, and then spinning, coagulating, forming, and stretching. of. The structural similarity between chitosan fiber and cellulose makes it not only similar to cellulose, but also has a wider range of uses than cellulose based on the characteristics of amino polysaccharides.

Studies have shown that chitosan fiber has significant antibacterial and antifungal effects and functions of promoting skin growth, and can be widely used in beauty and skin care products. At the same time, chitosan fiber has special properties such as biological activity and bioaffinity, biodegradability, biocompatibility, non-toxicity, and low immune antigenicity, and has the natural advantages of preparing skin care and beauty masks.
