Korean commercial Bombyx mori silkworm cocoon made by Kumokjam and Daesungjam was examined to characterize for application. Amino acid analysis showed that the main amino acid of Kumokjam and Daesungjam cocoon was glycine, alanine, serine, tyrosine, and aspartic acid. The content of three major amino acids was about 67% and the content of long chain amino acids was about 37%. Stress-strain curve showed that breaking stress of Kumokjam cocoon, 50 MPa, was higher than that of Daesungjam cocoon, 48 MPa. Breaking strain of Kumokjam cocoon, 37%, was also longer than that of Daesungjam cocoon, 30%. These results might be used as basic information for development of nontextile materials using Bombyx mori silkworm cocoon.
