摘　　要：段彩纱是一种沿纱线纵向色彩呈分段变化的花式纱线,现有的生产工艺不可避免产生竹节纱的效果,导致不能大规模的推广。本文改进了细纱机的牵伸机构,制备线密度恒定,而组分、色彩是分段变化的棉段彩纱,并探讨分段时间、某一分段时间内两组份的质量比例对成纱性能的影响。结果表明,通过合理控制后区牵伸工艺,可以生产线密度恒定且性能良好的段彩纱。Segment colored yarn is a kind of fancy yarn whose color changes regularly segment-by- segment in yarn length direction. The present processing technology inevitably produces slubby yarn effect. Therefore this paper employed a modified draft system of ring spinning machine to produce segment colored cotton yarn with constant linear density but component and color changing segment-by- segment. The effects of segment time and mass ratio of two components within a given segment time on the properties of the formed yarn were investigated. The results indicated that segment colored yarn with constant linear density and good quality can be produced by proper control of back zone draft process.
