摘　　要：为揭示转杯纺复合纱结构与其拉伸性能间的关系,通过理论分析与实验研究讨论转杯纺复合纱的结构和拉伸断裂的过程与特征,并通过科视达视频显微镜观察不同结构复合纱的断口形态。研究结果表明:转杯纺复合纱的结构取决于长丝张力和短纤维纱条张力间的差异,在短纤纱纺纱条件不变时,通过调整长丝超喂率可得到不同结构的转杯纺复合纱;复合纱的结构不同,其拉伸断裂的过程和断口形态也有较大差异;与相同工艺条件下纺制的纯棉转杯纱相比,复合纱的拉伸性能有较大改善。For discovering the relationship between structure and tensile properties of rotor-spun composite yams, the yam structure and tensile characteristics were investigated by theoretical and experimental methods, and the morphology of yarn breakage ends were observed by the Questar hi-scope video microscope system. The results indicate that the structure of composite yarns depends on the difference between the filament tension and the tension of staple fiber strand. By controlling the filament over-feed ratio, different kinds of composite yams can be produced under the constant conditions of normal rotor spinning. The tensile process and breakage ends morphology of composite yams are related to the yarn structure. Compared with the normal rotor-spun yarn, tensile properties of composite yarns are improved.
