Gluten fiber preparation method

Abstract

The invention relates to a gluten fiber preparation method which comprises steps as follows: (1), preparation of a spinning solution; (2), spinning with a wet method; (3) solidification; (4) crosslinking treatment of citric acid; (5), secondary drafting; and (6), thermal treatment for sizing. The gluten fiber preparation method has the advantages of low production cost and simple and efficient production process of gluten fiber.

Description

technical field [0001] The invention relates to a method for preparing protein fibers, in particular to a method for preparing protein fibers using gluten as a raw material, and belongs to the technical field of polymer materials. Background technique [0002] my country is the center of the global textile industry. The textile industry is a traditional pillar industry of China's national economy and an important livelihood industry. The overall textile production capacity is close to half of the world's. At present, my country's textile consumption needs have shifted from subsistence consumption to enjoyment consumption, and gradually changed from a textile production base to a consumer subject. People's demand for high-quality textiles is increasing day by day. Demand is also increasing. Commonly used traditional natural protein fibers include plush and silk fibers. These two types of fibers are favored by consumers for their excellent wearability such as good comfort, go...

Problems solved by technology

At present, the regenerated protein fibers that have been industrialized, including soybean protein fiber and milk protein fiber, are not 100% soybean protein regenerated fiber or milk protein regenerated fiber, which contains about 55-75% synthetic polymers. These fibers are difficult to meet the fiber quality requirements of high-end textiles

[0003] Chinese patent: Publication No. CN1370856 discloses a regenerated protein fiber and its manufacturing method, which uses keratin as the preparation method of the regenerated protein fiber as a raw material, but the number of disulfide bonds between keratin macromolecules is huge, and the spinning solution During the preparation process, it is difficult for the protein to fully swell and stretch, and the strength of the fiber cannot be guaranteed. A large amount of toxic mercaptoethanol or thioglycolic acid and other substances are used in the preparation process of the fiber. The production process is complicated and the safety is insufficient.

Chinese patent: Publication No. CN102634860A discloses a wheat protein fiber and its manufacturing method. The fiber prepared by this method has a low protein content, and a large amount of sodium hydroxide solution and sulfuric acid solution are used in the preparation process, causing great pollution in the production process.
