Problems solved by technology

[0002] Protein fibers purely regenerated from proteins do not have practical properties due to their low dry and wet breaking strengths
In recent years, professional technicians in this field have begun to improve the physical and chemical properties of protein fibers by mixing and spinning proteins and synthetic polymers, such as: patents ZL99116636, ZL02101961, ZL02155315, ZL00116211 and my patent applications ZL01138897, ZL01106274, ZL01128117, etc. Disclosed are various protein raw materials and polyvinyl alcohol or polyacrylonitrile blending, the manufacture method of copolymerization fiber, although the physical and chemical property index of protein fiber has been improved, but because the content of synthetic high molecular compound among them is as high as 70~85%, so First, synthetic fibers (acrylic, vinylon) have poor hygroscopicity, strong static electricity, poor dyeability, and incomplete biodegradability and other defects.

Abstract

The invention relates to a protein and alginate composite fiber which is a regenerated protein composite fiber containing 5-90% of natural protein and 10-95% of natural alginate. The protein and alginate composite fiber is manufactured by the technological processes of raw liquid preparation, wet spinning, crosslink finishing and the like. The protein and alginate composite fiber has good hydroscopic property, antistatic property, dyeing property and flame resistance, can be completely degraded biologically, is a real green ecological textile material, has soft and smooth hand feel, is suitable for spinning and processing underclothes, articles for bedrooms, articles for health care and the like, and is suitable for manufacturing hairline for wigs because of good flame resistance.

Description

technical field [0001] The invention relates to a composite fiber made of protein and sodium alginate and a manufacturing method thereof. It belongs to the field of new chemical fiber materials. Background technique [0002] Protein fibers purely regenerated from proteins do not have practical properties due to their low dry and wet breaking strengths. In recent years, professional technicians in this field have begun to improve the physical and chemical properties of protein fibers by mixing and spinning proteins and synthetic polymers, such as: patents ZL99116636, ZL02101961, ZL02155315, ZL00116211 and my patent applications ZL01138897, ZL01106274, ZL01128117, etc. Disclosed are various protein raw materials and polyvinyl alcohol or polyacrylonitrile blending, the manufacture method of copolymerization fiber, although the physical and chemical property index of protein fiber has been improved, but because the content of synthetic high molecular compound among them is as h...
