Title:
PREPARATION METHOD FOR CHITOSAN-ALLANTOIN REGENERATED CELLULOSE FIBERS
Document Type and Number:
WIPO Patent Application WO/2019/109646
Kind Code:
A1
Abstract:
A preparation method for chitosan-allantoin regenerated cellulose fibers. Specifically, the method comprises: adding chitosan to an alkaline solution of allantoin, and then performing spinning by blending the mixture with a viscose spinning solution, so as to prepare the regenerated cellulose fibers. Chitosan is dissolved in the alkali solution of allantoin, the solubility of chitosan in the alkali solution can be greatly improved by means of the characteristic of similar structures of allantoin and chitosan, the defect of reduction of various properties of fibers prepared by using the traditional preparation method of the viscose fibers of the chitosan in which chitosan powder is directly blended is overcome, and accordingly, the distribution of chitosan in the fibers can also be improved, and the antibacterial effect and durability of the fibers are improved.
