Milk protein fiber or its filament or its blended yarn dyeing method and coloured woven fabric producing method

Abstract

The invention relates to a production method of milk protein fiber or its filament or its blended yarn dyed and yarn-dyed products. In the production process of package yarn dyeing, by changing the yarn winding density, controlling the heating rate, adopting segmental shrinkage, and adding self-made special auxiliary for milk protein fiber dyeing during dyeing, polyacrylonitrile or polyacetic acid Dyeing technology of milk protein fiber reactive dyes with vinyl alcohol as the carrier; solved the problem of dyeing high proportion or purely spun milk protein fiber and its filament and its blended yarn; Uniformity, opaque dyeing, low coloring rate and poor color fastness. Colored yarns are weaved, shrunk, softened, and post-treated to obtain yarn-dyed products with good shrinkage and stable dimensions. The invention has the advantages of smooth, soft, lint-free and lint-free surfaces of yarns and colored fabrics; uniform color, no color difference, no color flowers, high color fastness, good dyeing reproducibility, high production rate, and is convenient for production and cooperation. application.

Description

technical field

[0001] The invention relates to a production method of milk protein fiber or its filament or its blended yarn dyed and yarn-dyed products, in particular to a milk protein fiber and its filament and its doubling, twisting, core-spun yarn or its short The invention relates to a method for producing fiber blended yarn dyeing and yarn-dyed products, belonging to the technical category of yarn dyeing and yarn-dyed products production and weaving. Background technique

[0002] Milk protein fiber and its filaments are high-grade new fiber materials. It combines the advantages of various natural protein fibers and chemical fibers. Excellent mechanical properties; good spinnability; compatibility with other fibers; not afraid of moths; antibacterial, antibacterial, health care and other properties as one. However, the immaturity of milk protein fiber dyeing technology restricts and hinders its application and promotion in the textile industry.
