细纱机第三代大牵伸工艺机理浅析

A primary analysis of the third generation of long drafting technology of spinning frame

对细纱机第三代大牵伸工艺影响产品质量的机理进行了分析,认为采用第三代大牵伸工艺后,钳口的摩擦力界得到增强,浮游纤维得到有效控制,纤维变速点集中而前移,纤维的运动更趋平稳,产品质量有所提高,特别是每千米细节、粗节、棉结明显下降。

This article has primarily analyzed the reason of the influence of the third generation of long drafting technology on the product quality, holding that by use of the third generation of long drafting technology, the friction force of the nips is increased, the floating fiber is effectively controlled, fiber speed changing point goes forward and fiber movement is more stable which lead to the improvement of product quality with obvious reduction of thin or thick places and neps.
