Abstract
A method of manufacturing a blend composition, comprising: providing caprolactam; heating the caprolactam to a temperature of about 215° C. to about 280° C. for polymerization to form polycaprolactam; and mixing the polycaprolactam at the temperature of about 215° C. to about 280° C. with collagen, such that the collagen is denatured by heat, wherein the denatured collagen has a first polypeptide, a second polypeptide, and third polypeptide, and amide groups of the first polypeptide, the second polypeptide, and the third polypeptide are linked with amide groups of the polycaprolactam through hydrogen bond formation, thereby the blend composition is formed.
