Abstract

The invention relates to a hair keratin composite fiber and a spinning method thereof. The hair keratin composite fiber comprises: by weight, 1 to 60 parts of hair keratin and 40 to 99 parts of polyvinyl alcohol. Hair keratin raw materials of the hair keratin composite fiber comprise low-value and low-price short pig hairs separated from bristles, short hair wastes, poultry feathers and wool residues from a woolen mill. A hair keratin and polyvinyl alcohol extracted from pig hairs, hair wastes, wastes of a woolen mill and poultry feathers are used as main raw materials and are processed into the hair keratin composite fiber. The hair keratin composite fiber greatly reduces a production cost, improves product performances and has a good application prospect. The hair keratin composite fiber satisfies green ecological textile requirements.

Description

technical field [0001] The invention relates to a hair keratin protein composite fiber and a spinning method of the composite fiber, belonging to the field of regenerated protein fibers. technical background [0002] In recent years, the protein fibers made of milk protein, soybean protein and silkworm chrysalis protein have begun to take shape. Textile products made of milk protein fiber and soybean protein fiber can be seen on the market, but the value and price of milk protein and soybean protein are different. Relatively high makes the market price of protein fiber very high, which affects its large-scale application, so only a small amount of textile products of protein fiber can be seen on the market. Contents of the invention [0003] The purpose of the present invention is to provide a hair keratin composite fiber to reduce cost. [0004] The object of the present invention is also to provide a spinning method of hair keratin composite fiber. [0005] In order to...
