摘　　要：测试了变异山羊绒单纤维压缩弯曲性能、拉伸性能和结晶度.经过对变异山羊绒各种纤维类型的分析比较,发现在压缩弯曲性能中,绒纤维和二细纤维的峰值力和抗弯刚度较小,而两型纤维和粗毛较大;在拉伸性能中,粗毛的断裂强力和断裂伸长率都较大;对于各纤维类型的断裂强度,则是绒纤维较大,其次是两型纤维、粗毛,最后是二细纤维.X射线衍射法测试了变异山羊绒不同类型纤维结晶度,其中二细纤维较小.The physical property of variational cashmere fibre, such as the compression bending perform- ance,the tensile properties and the crystallinity are tested and analyzed. Among of the four types of the variation cashmere fibre, for the compression bending performance, the peak value of force and the flexural rigidity of the the flocking fibre and the second-fine fibre are smaller than those of the two dimor phic fibre and the hair fibre for the tensile properties, the breaking strength and elongation of hair are larger for the breaking tenacity, caskmere fibre is bigger, followed by dimorphic fibre, hair fibre, and the second fine fibre. The crystallinity of different types of cashmere fibre was tested by the X-ray dif- fraction method. The crystallinity of the second fine fibre is smaller than others.
