【摘要】 应用X衍射分析、贝克线法、单纱强力测试和水洗色牢度测试等手段,研究以温度、张力、助剂等为主要工艺因素的特殊热处理对蚕丝丝素结构和性能的影响,以寻求对蚕丝丝素进行改性的新途径。结果表明:湿热条件下,张力作用能增加蚕丝纤维的取向度和结晶度,从而提高蚕丝的断裂强度和耐洗色牢度。润湿保护剂对蚕丝纤维有良好的润湿膨化作用和一定的高温保护作用,有助于上述处理效果的提高。更多还原

【Abstract】 Silk fibroin is modified by special heat treatments based on various temperature, tension and auxiliary. The orientation and crystallinity of the modified silk fibre are determined by BECK line and XRD analytical techniques respectively. And the breaking strength and the color wash_fastness of the modified silk are investigated. The results show that the tension in steaming process can improve the orientation and crystallinity of silk fibroin, increasing the breaking strength and the wash_fastness; the auxiliary with excellent wetting property and high_temperature protection property, is helpful to the effect of the special heat treatment.更多还原
