DEVELOPMENT OF REGENERATED PROTEIN FIBER FROM COLLAGEN AND WATER-SOLUBLE POLYMER COMPLEX

摘要

A method for manufacturing a regenerated protein fiber is provided to supplement the material property of the protein fiber, by adding polyvinyl alcohol and alginic acid into collagen protein so as to form a spinning solution for the protein fiber. A spinning solution is formed by mixing collagen protein, polyvinyl alcohol, and a cross-linking material, wherein the collagen protein is obtained by using saving scrap as a raw material. The spinning solution is wet-spun within a coagulation bath containing two or more kinds of coagulation material. The resultant material is chemically cross-lined within a cross-linking bath containing a cross-linking material. The spinning solution is formed by mixing the collagen protein, the polyvinyl alcohol, the cross-linking material, and alginic acid of 0.1~10 wt%.
