摘　　要：用稀土金属离子通过形成配位结合来固着丝胶 ,制备了不同增重率的丝纤维 ,研究了增重丝纤维结构变化。与未增重丝纤维相比 ,增重丝纤维的纵向形态和截面形态发生了变化 ,增重丝纤维中氮元素和碳元素的含量呈下降趋势 ,增重丝纤维中极性氨基酸含量增加 ,增重丝纤维的结晶度随着增重率的增加而下降 ,增重丝纤维热分解峰顶温度变化不明显。The structure changes of silk fiber with different weight gain, by using sericin fixing agent containing rare earth metal ion, were studied in this paper. Compared with control silk fibers, it is demonstrated that the fibroin surface morphology of in longitude and fibroin cross-section of weighted silk fiber were changed, the contents of nitrogen and carbon were decreased, and with increased weight gain, the crystallinity were decreased, while the contents of polar amino acid increased and the temperature of decomposition peak didn't change significantly.
