摘　　要：为了研究错位纺纱角的变化对纱线质量的影响,设计自制了一个导纱装置,在环锭细纱机前罗拉钳口至导纱钩之间形成一个偏移的纱路;在纺纱角分别为0°,4.2°,8.4°,11°,16.6°时纺20s,30s,50s,70s和90s Z捻左斜纱,然后测试纱线毛羽、条干和强力性能指标。结果表明,在Z捻左斜情况下,纱线有害毛羽最多可以减少16.6%～40.5%,且与细号纱相比,粗号纱的毛羽得到了更大改善;不同纱支的最佳左斜角不同,粗号纱和细号纱适应8.4°～11°大角度偏移量,中号纱只要4.2°小角度偏移就能很好地改善纱线毛羽;但偏移量≥16.6°的过大偏移量对改善毛羽是不利的,甚至会导致毛羽恶化。纺纱角对纱线条干影响不大,纱线强力几乎不受影响。A yarn carrier was designed to study the effects of spinning angle on yarn quality. A modified yarn path between front roller nip and yarn guide in ring spinning was formed and the Z twist left oblique yarn of 20s, 30s, 50s, 70s and 90° were spanned with the spinning angles of 0°, 4. 2°, 8. 4°, 11° and 16. 6°. The yarn performance of hairiness, evenness and strength were tested. The results indicated that 16.6% °40. 5% hairiness was reduced. The roving yarn hairiness was improved better compared with the fine yarn. The best spinning angle changed with counts. The roving and fine yarn prefer the bigger spinning angle 8. 4°11°, while 50s 70° yarn prefer smaller spinning angle 4.2°. However, hairiness got worse when spinning angle was over 16. 6°. The spinning angles had little effects on yarn evenness and no effects on yarn strength.
