Chitin is a kind of animal cellulose, which exists in the shell of crustaceans such as shrimp, crab and insects and in the cell membrane of mushrooms, fungi and bacteria. Chitin fiber is alkaline and highly chemically active, so it has excellent properties such as good adsorption, bonding, sterilization and air permeability.
Because the raw materials of chitin fiber basically come from people's waste shrimp and crab shells, it will not harm natural resources, but also reduce the pollution of this kind of waste to the environment.
At present, the raw material cost of chitin fiber is high. The spunlaced non-woven fabric made of chitin fiber is mainly used in the field of medical and health, high-grade beauty, artificial blood vessels, artificial skin and other biomedical engineering fields.
