摘要: 在2种长丝超喂率下,通过调整复合纱的捻系数使棉纤维和涤纶长丝复合以纺制不同类型的转杯纺复合纱。测量了纱线张力并研究了加捻对转杯纺复合纱结构和性能的影响。结果表明,复合纱捻系数在2种长丝超喂率下对复合纱的结构和性能都有显著的影响;涤纶长丝在复合纱中是以螺旋线形式与棉纤维纱条加捻复合,当长丝张力随着复合纱捻系数的增加和长丝超喂率的减小而增加时,长丝趋向于复合纱内层,复合纱的主要性能也会随之发生变化;与常规转杯纺纱线相比,复合纱表面较光洁,结构较紧密,主要性能得到了改善。

Abstract: At two filament over-feed ratios,different kinds of rotor-spun composite yarns were produced by combining cotton fibers with polyester filaments under varying twisting factors.The yarn tensions were measured and the effects of twist factors on the structure and properties of rotor-spun composite yarns were investigated.Results show that twist factor has great influence on the characteristics of composite yarns at two filament over-feed ratios.The polyester filament in the composite yarn is twisted with the cotton strand and follows a helical path.When the filament tension increases with increasing yarn twist factors and decreasing filament over-feed ratio,the filament yarn tends to lie near the inner layer of the composite yarn and the properties of composite yarns will change accordingly.Compared with the normal rotor-spun yarn,the appearance of composite yarns is clearer,more compacted and the properties are improved.
