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

Abstract

The invention discloses a manufacturing method of milk protein fiber or filament or blended yarn dyeing and yarn-colored product, which is characterized by the following: changing coiling density of yarn; controlling heating temperature; adopting segmented contraction in the cylinder yarn dyeing course; adding self-producing milk protein fiber dyeing specific adjuvant; utilizing polyacrylonitile or polyvinyl acetate alcohol as carrier realize active dyeing technology of milk protein fiber; solving the difficulties of flower color, weak color and bad fastening degree problem to produce excellent washing shrinkage and stable size yarn-dyed product through weaving, shrinking and softening and final disposal.

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 discloses a method for producing fiber blended yarn dyeing and yarn-dyed products, belonging to the technical field 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.
