[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 discloses a protein and cellulose composite fiber, which is the regenerative protein composite fiber containing 5-50% of natural protein, 50-95% of natural cellulose and 0-30% of alginate, and the fiber is prepared by the technical processes of stock solution preparation, wet spinning, crosslinking finishing and the like. The fiber has the advantages of good hygroscopicity, antistatic property, good dyeing property and complete biodegradability, and the alginate is added in the fiber for leading the fiber to have good flame-retardant performance, thereby being a real green raw material for ecological textiles. The fiber has soft and smooth hand feeling, thereby being applicable to underwear processing, bedroom supplies, sanitary and health care supplies and the like of the textiles.

Description

technical field [0001] The invention relates to a composite fiber made of protein, cellulose 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 t...
