摘　　要：段彩纱属于花式纱的一种,它利用不同原料、不同颜色纤维组合纺纱,使不同纱段具有不同的色彩、性能。同轴后罗拉牵伸机构可纺制等线密度段彩纱,但过渡段经前区牵伸变长,达6cm以上。采用新开发的同轴中罗拉牵伸机构结合气流集聚方法可纺制过渡段不超过2cm的等线密度段彩纱。主要分析分段时间对纺出纱线的条干均匀度、强力、毛羽指数的影响,使得这种纱线和工艺能更好地被应用在实际生产中。Segment color yarn belongs to fancy yarn. It uses different raw materials and fibers of different colors for spinning, thus making different yarn sections have different colors and performances. Coaxial back roller drafting mechanism can spin segment color yarn with equal fineness. However, the transition section elongates due to drafting of front zone and reaches over 6era. Segment color yarn with equal fineness with transition section less than 2era can be spun by using the newly developed coaxial middle roller drafting mechanism in combination with the method of airflow aggregation. This paper mainly analyzes the influence of split time on yarn evenness, strength and hairiness index of yarns spun, thus making such yarn and process better applied in actual production.
