摘  要:为了研究短纤皮芯结构纱的结构性能,对环锭纺粗纱机进行改造,纺制出3种皮芯比例、4种细纱捻度共6组棉涤短纤皮芯结构纱。通过包芯纱粗纱和细纱横截面图像分析,对比了包芯纱的包覆效果;通过毛羽、条干以及拉伸测试分析,对比了包芯纱的性能指标。结果表明:所纺制包芯纱均有较好的包覆效果,皮、芯层凝聚良好;包芯纱短毛羽随芯纱比例增加而降低;包芯纱条干随着芯纱比例增大而恶化,随捻度增大而改善;包芯纱断裂强度随着芯纱比例增加呈现出先增加、后减小的趋势;随着捻度增加,断裂强度表现出先增加、后减小趋势。认为:合理选择芯纱比例和捻度有利于改善短纤皮芯结构纱的包覆效果和性能指标。In order to study structure property of staple core-spun yarn,roving frame of ring spinning was modified.Six cotton polyester staple core-spun yarns with three kinds of surface core percentages and four kinds of yarn twist were spun.Through analyzing cross section images of core-spun roving and spun yarn,covering effect of core-spun yarn was compared.By analyzing hairiness,evenness and tensile property,property index of core-spun yarn were compared.Test results showed covering effect of the core-spun yarn were better.Cohesion between surface and core layers were better.Short hairiness of core-spun yarn was decreased as core yarn proportion increase.Evenness of core-spun yarn was worse as core yarn proportion increase and was improved as twist increase.Breaking strength of core-spun yarn was showed trend of increase first and decrease later as core yarn proportion increase.As increase of twist,breaking strength was showed trend of increase first and decrease later.It is considered that selecting core yarn proportion and twist reasonably is beneficial to improve covering effect and property indicators of staple core-spun yarn.
