Problems solved by technology

Therefore, it is difficult to spin qualified fibers from the spinning stock solution made of collagen protein; while the protein in the plant protein fiber spinning stock solution comes from by-products of oil crops, and the oil extraction process is subjected to high temperature and high pressure, which makes the protein subject to varying degrees. Denaturation or destruction greatly reduces the protein utilization rate and correspondingly increases the cost
Spinning fibers with this kind of spinning dope has many disadvantages, so the scope of use of fibers is limited.

Abstract

The invention relates to a regeneration animal-plant double-protein composite fiber spinning solution and a production method thereof. The protein regeneration composite fiber spinning solution includes an animal protein and / or a plant protein, the animal protein is sericin protein obtained by processing of reeling silk leftovers, and the plant protein is a protein obtained by extraction of multiploid locust leaves. The protein regeneration composite fiber spinning solution also includes the following components by weight: 0-40 parts of the animal sericin protein, 0-40 parts of the plant polyploid locust leaf protein, 58.6-74.4 parts of polyvinyl alcohol, 0.3-0.8 part of potassium sulfite or potassium bisulfite and 0.3-0.8 part of hydrogen peroxide, performic acid or peracetic acid; and then the composite spinning solution with the viscosity of 800-1200 centipoises is obtained by adding water and sodium hydroxide for copolymerization. According to the regeneration animal-plant double-protein composite fiber spinning solution and the production method thereof, the cost of fiber is reduced, the quality of products is improved, and the problems of chromaticity, color fastness, resistance to hot water and boiling water shrinkage of the fiber are solved.

Description

technical field [0001] The invention relates to a spinning stock solution of a new type of textile material, in particular to a spinning stock solution of a protein regenerated composite fiber co-polymerized with animal and plant double proteins and polyvinyl alcohol and a production method thereof. Background technique [0002] Known artificially synthesized animal protein fibers are mainly milk protein fibers, soybean protein fibers, and animal and plant protein synthetic fibers (animal proteins include casein, cortical collagen, and insect proteins; plant proteins include: by-products of various oil crops). In the above protein fiber production, the spinning dope is the key to fiber production, and the source and treatment process of protein is the key to the production of spinning dope. [0003] At present, the cost of the raw milk protein fiber spinning solution produced is high; while the cortical protein belongs to collagen protein. Collagen protein is characterized ...
