摘　　要：为制备高质量的轻量包芯纱,文章研究了同等芯丝规格条件下,如何用较少含量的外包纤维实现不露芯的高包覆效果,同时分析了纱线各组分比例对包芯纱毛羽、条干、织物耐磨等指标的影响。具体地,以4.44 dtex的DTY涤纶丝为芯丝,纺制了不同比例外包棉的包芯纱,并研究了外包纤维定量对纱线毛羽和条干的影响及对织物耐磨性的影响,最终开发了棉涤比例58/42且包覆率在80%以上,包覆效果良好的棉涤包芯纱。测试结果表明,5组不同比例的包芯纱有害毛羽数量均可以控制在24根/m以下;条干CV值与不匀率在外包纤维比例达到60%时产生突变,织物耐磨次数随着外包纤维定量下降呈现下降趋势。This paper examines the production of high-quality lightweight core-spun yarn by achieving a high covering effect with a reduced amount of outer fibers,while maintaining the same core filament.It also analyzes the impact of each component ratio of the yarn on factors such as hairiness,evenness,and wear resistance.Specifically,with 4.44 dtex DTY polyester filament as the core filament,core-spun yarns with different ratios of outer cotton were spun;and the effects of outer fiber ratios on yarn hairiness and evenness,as well as on the abrasion resistance of the fabrics were studied.In the end,a cotton polyester DTY corespun yarn with high covering effect of over 80%was developed when the ratio of cotton/polyester was 58:42.The test revealed that the number of harmful hairs in five groups of core-spun yarns with various ratios could be kept below 24 pieces per meter.When the ratio of outer fibers reached 60%,the CV value and the yarn unevenness change suddenly.And the wear resistance decreased as the quantity of outer fibers decreased.
