Abstract

The invention which provides a pressure washing technology suitable for the refinement of a protein viscose filament belongs to the viscose filament production field in the textile industry. The technology aims to solve problems of low strength, easy powder dropping, nonuniform dyeing, and environment pollution of protein fibers in the prior art, wherein the problems are caused by the dissolving and the shedding of proteins on the protein fibers in an alkali washing step in the pressure washing flow. By improving the water washing technology, the pressure washing of the protein fiber viscous filament can be effectively carried out, and the finished protein viscose filament has the advantages of high strength, difficult powder dropping, uniform dyeing, and no pollution to environment.

Description

technical field [0001] The invention relates to a refining process of viscose filaments. More specifically, the invention relates to a pressure washing process suitable for refining protein viscose filaments, which belongs to the field of viscose filament production in the textile industry. Background technique [0002] Protein fiber is a kind of composite fiber material obtained by blending or grafting copolymerization of animal and vegetable protein and fiber raw materials, and then post-processing. Commonly used animal proteins include: milk protein, silkworm chrysalis protein, plant proteins include soybean protein, peanut protein, corn protein, etc., and fiber raw materials include polyvinyl alcohol, polyacrylonitrile, and regenerated cellulose. The protein in the protein fiber contains a variety of amino acids. The protein fiber has the function of skin care and health care. It is suitable for making underwear and is comfortable to wear. It is very popular among consum...
