摘　　要：为了探究超大牵伸条件下纤维变速点分布与成纱质量之间的关系,先以定量为16.0 g/5 m的熟条来纺制定量分别为3.54、4.32、5.51、6.20 g/10 m的粗纱,而后在含有四罗拉四皮圈的TH558型三区超大牵伸细纱机上分别以50、60、70、80倍的前区牵伸倍数来纺制5.8 tex的细纱,并测试不同前区牵伸倍数下的纤维变速点位置,对纤维变速点分布进行统计分析,从而探究前区牵伸倍数对纱线质量的影响。结果表明:当前区牵伸倍数为60倍时,纤维变速点分布更集中、稳定、前移,且纱线的各项性能较为理想;在一定范围内,随着前区牵伸倍数的增大,变速纤维集中位置变得分散、后移且不稳定,条干不匀增加,纱线质量变差。The relationship of accelerated-point distribution of fibers and yarn quality in the super high draft spinning frame is studied, Firstly, the rovings with 3.54,4.32,5.51,6.20 g/10 m are prepared by the cotton sliver of quantitation 16.0 g/5 m. Then, 5.8 tex cotton yarns are spun respectively with 50, 60, 70, 80 draft multiple of front draft zone on the TH558 four-roller and four-apron super high draft spinning frame. And the accelerated-point distribution of fibers under different draft multiple of front draft zone is tested and explored to study the effect of draft multiple of front draft zone on yarn evenness. The results indicate that when the draft multiple of front draft zone is 60, the accelerated-point is more concentrated, stable and forward, and the properties of the yarn are relatively ideal. As the draft ratio increased within a certain range, the accelerated-fiber centralized location becomes more cluttered, backward and unstable, unevenness increases and yarn quality declines.
