摘　　要：应用自行研制的直接测量纱线扭矩装置 ,这里测试数种纱线的扭矩 -捻度关系曲线及其在常温和热状态下的扭应力松弛关系曲线 ,分析相同捻度下各种纱线扭矩差异的根源 ,发现涤长丝与毛短纤复合纱线的特殊结构是造成复合纱线残余扭矩较大的主要原因。这里的测试结果可作为纱线的捻度设计及捻度定型工艺设计的参考依据。An apparatus made by our lab is used for direct measurement of torque of yarns. The torque-twist relation curves, torque-relaxation behavior of several kinds of yarns at room temperature and heat-setting temperature are given. After analyzing the difference of different yarn torque it can be found that the special structures of composite yarns made of polyester filament and wool staple fibers mainly cause the high residual torque. The results presented in this paper can provide the referential basis for designing the yarn twist and determine the process of heat setting.
