Abstract

The invention provides a shrink-proof treatment method for cashmere fibers, and relates to the technical field of textile fiber treatment, and the shrink-proof treatment method comprises the following steps: step 1, plasma pretreatment; step 2, composite enzymatic hydrolysis treatment; step 3, carrying out macromolecule grafting treatment; step 4, carrying out cross-linking curing treatment; and step 5, after-finishing treatment. The compound enzyme solution contains papain, laccase, alkaline pectinase and sodium hydrogen sulfite. According to the shrink-proof treatment method for the cashmere fibers, through a four-step composite process of plasma activation, composite enzymolysis, biopolymer grafting and cross-linking solidification, the oriented friction effect of cashmere fiber scales is weakened, meanwhile, a stable biocompatible protective layer is formed, and the shrinkage-proof effect of the cashmere fibers is improved. Collaborative optimization of the shrink-proof effect and the natural performance of the fiber is realized; meanwhile, a core material preparation method, equipment parameters and process details are defined, and it is ensured that the technical scheme is repeatable and industrial safety is controllable.
