Wheat protein regenerated cellulose fiber and preparation method thereof

Abstract

The invention discloses a wheat protein regenerated cellulose fiber and a preparation method thereof. The cracking strength of the wheat protein regenerated cellulose fiber is 3.1-3.6 cN / dtex, the wetbreaking strength is 1.7-2.0 cN / dtex, the dry breaking elongation is 13-15%, the linear density is 1.67-4.44 dtex, ad the protein content is 1-8%. Protein used in the method is wheat protein micro-powder processed through a special method rather than hydrolyzed protein, so that a massive loss of hydrolyzed protein during spinning forming is avoided. The prepared regenerated cellulose fiber is relatively good in mechanical property and flexibility, and textiles prepared from the fiber have relatively good wear-resisting strength, elasticity, wrinkle resistance and drapability. In addition, when wheat protein micro-powder blending viscose is prepared, wheat protein micro-powder dispersion liquid is added into a modified viscose stock solution through injection before spinning, and a whole spinning system is not contaminated.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a wheat protein regenerated cellulose fiber and a preparation method thereof. Background technique [0002] Wheat contains about 13% protein, mainly composed of albumin, globulin, gliadin and glutenin. Due to the extensibility of gliadin, glutenin has elasticity , can form a network structure with water, so it has excellent viscoelasticity, extensibility, water absorption, liposuction emulsification, film forming characteristics, and can also inhibit high blood pressure, improve immunity, nourish the heart and spleen, clear away heat and moisten dryness, Stop bleeding, disperse blood, treat edema, relieve exercise fatigue, etc. In view of the characteristics of wide sources of wheat protein, large output, low cost, and no harmful substances to human body, it is especially suitable for spinning into fibers. Protein fibers belong to the category of functional regener...

Problems solved by technology

[0003] CN1811020A discloses a manufacturing method of soybean protein and viscose blended fiber, which is prepared by wet spinning, and adds an acetal process in the post-treatment of the fiber. The manufacturing method of this application uses aldehydes to process In addition to the pollution of the environment and the impact on the quality of the protein fiber, the comfort of the prepared protein fiber is poor

[0004] In the preparation of the existing disclosed protein fibers, viscose fibers or other wet-spun synthetic fibers are generally used as the substrate, and animal or vegetable proteins are firstly hydrolyzed to obtain polypeptides or amino acids, which destroys the original structure of the protein, or uses aldehydes Acetalization of similar substances uses heavy metal chromium salts for denaturation and solidification, which not only affects the quality of protein fibers, but also causes environmental pollution
