Problems solved by technology

[0003] Most of the fibers modified from animal source proteins are dissolved by chemical methods, such as alkaline hydrolysis and enzymatic hydrolysis, and then added to the regenerated cellulose fiber by blending. This process needs to be contacted during the production process. Strong acid and strong alkali environment will cause a certain degree of damage and damage to the protein components, and during the fiber forming process, the protein components will be partially lost; through the way of injection before blending, if the protein solution is added too much, it will seriously affect the fiber. The spinnability of the fiber is high, and the fiber's physical performance index is deteriorated, which affects the final fiber performance.

Abstract

The invention provides a preparation method of a mouse hair modified fiber. The preparation method is characterized by comprising the following steps: (1) pretreating mouse hair; (2) crushing the mouse hair; (3) preparing a mixed dispersion liquid; (4) fiber treatment; and (5) post-processing the fibers. The fiber prepared by the method has higher dry breaking strength, wet breaking strength and dry breaking elongation; wherein the dry breaking strength is 2.42 CN / dtex or above, the wet breaking strength is 1.25 CN / dtex or above, the dry elongation at break is 18% or above, and the antibacterial rate is 94% or above.

Description

technical field [0001] The invention belongs to the field of light industrial textiles, and in particular relates to a preparation method of possum hair modified fibers. Background technique [0002] Regenerated cellulose fiber products are made of 100% pure natural materials, naturally biodegradable, no additives, no heavy metals, no harmful chemicals, and are friendly to the skin and non-irritating. It is an environmentally friendly "green" fiber with excellent performance. The fabric made of fiber is more comfortable to wear; the dyeing beauty is better than that of cotton fiber; the hand feels soft, plump and smooth, with excellent drape and silk-like luster; high thermal stability and light stability, no static electricity; strength And the elongation can meet the needs of most textiles, and has good spinnability. [0003] Most of the animal-derived protein-modified fibers are chemically dissolved animal hair, such as alkaline hydrolysis and enzymatic hydrolysis, and t...
