摘　　要：针对乌拉草/棉/维纶赛络纺包芯纱存在毛羽较多和条干较差等问题,加装导纱器引入外包缠纱,设计一种改善其条干和减少毛羽的新型纺纱方法:改进型赛络菲尔纺。对影响纱线性能较大的纱线捻系数与导纱间距进行了实验,并以断裂强度、断裂伸长率、毛羽指数和条干均匀度为性能评价指标,对改进型赛络菲尔纺制备的乌拉草/棉/维纶复合纱的工艺进行模糊综合评价。结果表明:捻系数对纱线性能影响顺序依次为400、380、360、340;改进型赛络菲尔纺在单纱间距为10 mm,捻系数为400时,复合纱的综合性能最好,与传统赛络菲尔纺工艺制备的包芯纱对比,毛羽指数下降了73.49%,条干不匀率减小了29.05%。In view of more hairiness and poor yarn evenness of Carex meyeriana/cotton/vinylon composite yarn,a new yarn spinning method（modified sirofil spinning） was designed in which yarn carrier was added to introduce external fascinated yarns.The influence of twist factor and spacing on the yarn performance was discussed using strength,extension at break,hairiness index and yarn evenness as evaluation indexes.The performance of the composite yarn was evaluated by fuzzy comprehensive evaluation.The results show that the influence sequence of the twist factor on the yarn performance sequentially is 400,380,360 and 340; the composite yarn has the best comprehensive performance when the single yarn spacing is 10 mm and the yarn twist factor is 400 in the modified sirofil spinning; and the hairiness is reduced by 73.49% and the unevenness is reduced by 29.05%,compared with core spun yarn spun by conventional sirofil spinning.
