拉伸羊毛的结构性能研究

Research on structure and property of stretched wool

对70s原毛条、70s国产拉伸毛条、70s日本拉伸毛条、80s原毛条、80s国产拉伸毛条和山羊绒进行比较研究,认为拉伸羊毛的细度、鳞片间距和形态接近山羊绒,但鳞片厚度和翘角与山羊绒差距较大,日本拉伸羊毛稍好,但有剥蚀痕迹.与原毛相比,拉伸羊毛摩擦系数增大,力学性能变好,细度增加,吸湿性能发生了较大变化.

The study and analysis are conducted respectively on 70~s and 80~s unprocessed wool sliver, 70~s Chinese and Japanese stretched wool sliver, 80~s Chinese stretched wool sliver, and the cashmere fiber as well. Therefore it is believed that the fineness, the space between squama and the configuration of stretched wool are close to those of the cashmere fiber. However, the thickness and cock angle of squama are quite different from those of the cashmere fiber, in which the Japanese stretched wool, though having excoriation vestige, tops the best. Compared with unprocessed wool, the stretched wool not only possesses higher friction coefficient, better dynamic property and fineness but also changes a lot in its moisture absorbency.
