摘要(Abstract)：

采用还原法从羽毛中提取角蛋白,制得羽毛蛋白质粉,与聚乙烯醇进行湿法纺丝,制备羽毛角蛋白/聚乙烯醇共混纤维。共混纤维的力学性能测试表明:当共混纤维中羽毛角蛋白/PVA的质量比由1∶9提高到3∶7时,其强度由2.78cN/dtex下降到1.48cN/dtex。采用DSC、红外光谱仪、X-射线衍射仪、扫描电镜等对所得纤维的结构与形态进行了表征。结果表明:羽毛角蛋白分子和聚乙烯醇分子之间具有较好的相容性;随着羽毛角蛋白含量的增加,共混纤维表面粗糙度增加,甚至出现槽沟。
Feather keratin was extracted from feather via reduction method and feather keratin/ polyvinyl alcohol blend fiber was preared by wet spinning. The test of mechanical properities showed that the strength of the fiber was decreased from 2.78 cN/dtex to 1.48 cN/dtex when the weight ratio of feather keratin to PVA was increased from 1∶9 to 3∶7. The resultant fiber was also characteriazed by DSC, infrared spectrometer, X-ray diffraction and scanning electron microscopy. These results showed that feather keratin molecules and polyvinyl alcohol molecules had good compatibility. With the increase of the feather keratin, the surface roughness of the resultant fiber increased and had some grooves.
