摘　　要：应用扫描电镜、红外光谱、热分析、氨基酸分析等方法研究各茧层桑蚕丝纤维在形态结构、化学结构和微细结构上的差异 ,并比较分析各茧层蚕丝的练减率和活性染料的染色性能。结果表明 ,各茧层蚕丝纤维的径向尺寸和练减率有明显差异 ;各茧层蚕丝丝素蛋白的氨基酸组成种类相同但含量不一 ;各茧层蚕丝纤维的微细结构和热性能有一定差异。The differences in morphological structure,chemical constitution and micro\|structure of silk fiber in different cocoon layers were studied using a range of analytical techniques,scanning electron microscope(SEM),Fourier transform infra\|red spectroscopy in ATR mode (FTIR\|ATR),differential scanning calorimetry (DSC),amino acid analysis;The degumming loss percentage and the dyeing behavior with reactive dyes of the silk fibers in different cocoon layers were investigated.The results show that there are obvious differences in radial size and degumming loss percentage of silk fibers in different cocoon layers.Amino acid composition of silk fibroin in different cocoon layer is identical in category but different in content.There are some differences in micro\|structure and thermal property of silk fiber among different cocoon layers.
