Abstract

The invention relates to a composite fiber containing wheat protein and a preparation method thereof; the preparation method of the fiber comprises the steps of preparing a wheat protein composite solution, and preparing cationic fibers, cross-linked wheat protein and an adsorption plant extract; no strong acids are used in the method when the protein and plant extract are adsorbed, all effectiveingredients are not damaged, and therefore, the prepared composite fiber has good properties; the fiber prepared through the method disclosed by the invention has the advantages of bright and soft luster, good moisture absorption and release and good softness, has high dry breaking strength, wet breaking strength and dry breaking elongation, and has good antibacterial effect, wherein the dry breaking strength is greater than 2.25 CN/dtex, the wet breaking strength is greater than 1.25 CN/dtex, the dry breaking elongation is greater than 9%, and the antibacterial rate is higher than 95%.

Description

technical field [0001] The invention belongs to the technical field of light industry and textile, and in particular relates to a composite fiber containing wheat protein and a preparation method thereof. Background technique [0002] Protein is rich in 18 kinds of amino acids needed by the human body. Compounding protein in the fiber can not only maintain the original performance of the fiber, but also increase the skin-friendly and soft characteristics. At present, there are many protein fibers on the market that use cellulose fibers as carriers, such as silkworm chrysalis protein fibers, cashmere protein fibers, and silk fibers. Most of them are added by blending with viscose spinning dope. [0003] CN102304782A discloses a pupae protein viscose staple fiber and a manufacturing method thereof. The patent consists of pupae protein liquid and cellulose xanthate solution in a weight ratio of 1%-60%: 40%-90% through static blending, spinning Silk, coagulation, solidificatio...
