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.

丝废弃物化学处理过程中丝素的结构变化

使用粘度测定，十二烷基硫酸钠在聚丙烯酰胺凝胶中的电泳，红外光谱，动态光散射和X射线衍射研究了在丝制造废料化学加工过程中丝蛋白的结构变化。如果增加脱胶溶液的pH值，温度和脱胶时间，则水解破坏增加并且纤维蛋白分子量降低。提出了使丝纤维脱胶的最佳条件，该条件使多肽链的破坏最小。
