摘要
对ＩＮＡ—Ｖ牵伸中的后区牵伸效果进行了分析（摩擦力界分布、纤维变速点分布、纤维伸直效果及粗纱捻回的变化），并进行了纱线质量的对比试验。
This paper analyzed the featuresof the back drafting zone on INA-Vdraftins system (i. e. drafter, friction range distribution, fibre speed changing distribution, fibre straight, roving twist change ).And some yarn quality comparison testswere made.
