Problems solved by technology

Inconvenient during preparation
Trimethyl chitosan is a derivative of chitosan, besides good biodegradability, it also has good water solubility, but the degree of acetylation is lower than that of chitosan
[0003] Because chitosan molecular chains are connected with a large number of hydroxyl groups and amino groups, which carry positive charges for the molecules in acidic solution, which brings inconvenience to the preparation process, and the obtained chitosan fibers have low purity and poor spinnability.

Abstract

The invention discloses a chitosan fiber which comprises the following ingredients in parts by weight: 20-50 parts of chitosan, 1-10 parts of glycerol, 10-50 parts of zinc acetate, 1-15 parts of isopropanol, and 10-100 parts of microcrystalline cellulose. The invention aims at providing the chitosan fiber which is low-cost in raw materials, and wide in application range, and has the good biodegradability.

Description

technical field [0001] The invention belongs to the technical field of textiles and relates to a chitosan fiber. Background technique [0002] Chitin is a natural biopolymer extracted from the shells of shrimp and crab insects and the cell walls of fungi and algae. Chitosan is the product of deacetylation of chitin after treatment. Chitin fiber and chitosan fiber are natural polymer fibers spun from chitin and chitosan solution through high-tech processing. It has the characteristics of good biodegradability and can be spun into two categories: filament or short fiber. The filament is used for twisting medical sutures, and the short fiber is used to make medical accessories in the form of non-woven fabrics. Chitosan, the chemical formula is: (C 6 h 11 NO 4 ) n A large number of hydroxyl groups and amino groups are connected to the molecular chain, and its chemical properties are active. It cannot be dissolved in water and alkaline solutions, but can only be dissolved in...
