摘　　要：探讨段彩竹节纱节长节距偏差及修正方法。分析阐述了三罗拉段彩竹节纱装置纺纱原理及存在节长节距偏差的问题,通过试验分析了偏差的的大小、分布规律及产生的原因,提出了偏差修正方法并进行了试验验证,结果获得了较好的修正效果。认为:节长、节距偏差的形成是由三罗拉段彩纺纱装置特殊的纺纱原理所造成的;偏差的分布规律为:彩段呈正偏差,白纱段呈负偏差,两者的数量绝对值基本相同。采用等量增减输入参数的修正方法,可获得较好的修正效果,达到段彩竹节纱参数工艺设计要求。Methods of correcting slub length and slub distance deviation of segment-color slub yarn were discussed. Spinning principle of three-roller segment-color slub yarn device and problems of slub length and slub distance deviation were analyzed. Size, distribution rule and causes of the deviation were analyzed through tests. The correction method was put forward and verified, and the correction effect is better. It is considered that the deviations are caused by the special spinning principle of the device. The distribution of the deviations is that segment section is positive deviation and white section is negative deviation, the absolute values of the deviations are basically same. Better correction effect can be made and the processing parameter design demand of segment-color slub yarn can be reached by method of inputting pa- rameter in same increase amount or decrease amount.
