Soybean protein colored spinning fiber and its production method

Abstract

The invention provides a soybean protein colored fiber and production method. There is activated dye in soybean protein colored fiber. The production method is described as: during the process of making up filature original fluid, activated dye is put in, then colored fiber of plant protein whose density is 0.7-3.0dtex is ripened, get together and slubbed through technology of wet method filature in reactor. Because activated dye is put in during making up fluid coloring and sessile rates are increased. Coloring firming degree of the colored fiber can reach five grades after measuring.

Description

technical field

[0001] The invention belongs to textile materials, and in particular relates to colored spinning fibers composed of soybean protein fibers and reactive dyes, and also relates to a manufacturing method of the colored spinning fibers (hereinafter referred to as colored spinning). Background technique

[0002] Soybean protein fiber can be called "green fiber" in the new century. The globulin is separated from the oil-pressed soybean meal, and after linearization treatment, it is copolymerized and blended with a hydroxyl polymer to make a protein spinning solution, and the fiber is wet-spun. Disclosed in the national patent CN99116636.1 and CN02109966.9 is by the manufacture method of plant protein synthetic fiber and this fiber, but the fiber of its production need carry out bleaching and dyeing thereafter. Because the molecular chain of cellulose fiber is a polypeptide polymer, it is not resistant to caustic soda, and the protein fiber will be damaged to varyi...
