摘　　要：在经过改装的转杯纺纱机上,通过调整涤纶长丝的超喂率生产不同结构和性能的转杯纺复合纱。长丝超喂率对复合纱的外观、结构和性能均有较显著的影响。当长丝张力随长丝超喂率减小而增加时,长丝从复合纱表面逐渐趋向于分布在纱线内层。复合纱的拉伸性质、条干、毛羽等性能与长丝超喂率有密切联系。与纯棉转杯纱相比,复合纱的外观和性能均有较大程度的改善。Different kinds of rotor-spun composite yarns were produced by combining staple fibers with filament yarns under varying filament over-feed ratio on a modified open-end rotor spinning frame, and the effects of filament over-feed ratio on the structure and properties of composite yarns were studied. As the filament tension increases with decreasi＇ng filament over-feed ratio, the filament moves from the surface into the center of the composite yarn. The tensile properties, irregularity and hairiness of composite yarns significantly depend on the filament over-feed ratio, and the appearance and properties of rotor-spun composite yarns are improved compared with the normal rotor-spun yarn.
