摘　　要：我国山羊绒纤维的产量、质量均居世界首位,对其微细结构进行深入研究具有重要的理论及实践意义。采用X-射线衍射仪、差示扫描量热仪两种近代测试仪器,较深入地比较研究了山羊绒、羊毛纤维结晶结构的异同。研究结果表明,山羊绒纤维结晶度、α-结晶度高于羊毛纤维,大分子排列规整性好;羊毛纤维的结晶度、α-结晶度分别为山羊绒纤维的81.2％及75.8％。山羊绒、羊毛纤维DSC曲线均表现出α-结晶的双熔融峰,其熔融温度没有明显差异。Both the quality and quantity of Chinese cashmere are on the top in the world. It's important and necessary to study the fine structures of Chinese cashmere fiber. In this paper, the crystallitic structures of Chinese cashmere and fine wool fibers are comparatively investigated by using Wide Angle Xray Diffraction (WAXD) and Differential Scanning Calorimeter (DSC) methods. It is showed that the crystallinity and α-crystallinity of cashmere fiber are respectively higher than that of wool fiber. The crystallinity and α-crystallinity of wool fiber are respectively 81.2% and 75.8% of that of cashmere fiber. The DSC graphs of these two kinds of fiber show bi-modal melting peaks and similar melting temperatures of α-crystallinities.
