摘　　要：采用稀土溶液对脱胶桑蚕丝进行处理,用扫描电子镜、红外光谱、X射线等手段观察稀土处理后的丝素的微观形态结构和聚集态结构。表明,真丝纤维经稀土处理后,丝纤维表面有明显的分纤现象;丝纤维结晶度下降,取向度提高,纤维内部结构呈β化趋势,处理后丝纤维的断裂强度提高。s: With the methods of electron scanning micrograph (SEM),infrared spectrometry and X-ray, themicrostructure and aggregating state structure of the fibroin after treated with rare earth solution arestudied. It shows that after the treatment, the stripes along lengthways on the surface of silk fiber areobvious. The crystallinity of the silk fiber decreases, while the degree of orientation increases, andthe inner structure of the fiber is on the trend of β and the breakage strength is rise.
