摘要：
Structural changes occurring in fibroin during chemical processing of silk manufacturing wastes were studied using viscometry, electrophoresis in polyacrylamide gel with sodium dodecyl sulfate, IR spectroscopy, dynamic light scattering, and x-ray diffraction. Hydrolytic destruction increased and the fibroin molecular mass decreased if the pH of degumming solutions, temperature, and degumming time were increased. The optimal conditions for degumming silk fibers that minimized destruction of the polypeptide chains were proposed.
