粗纱重定量工艺的探讨

在重定量高效工艺中,如何使粗纱牵伸重定量适应梳理重定量带来的附加不均负效应,为细纱提供符合要求的粗纱,为此分析了重定量工艺对牵伸移距偏差、两对力、须条不匀的组成以及纤维运动的影响,重点从牵伸型式、牵伸工艺、钳口工艺、牵伸倍数、附加牵伸元件等方面阐述了重定量工艺对粗纱工序以及粗、细纱工艺配合的影响与控制.指出:重定量工艺...

Approach into the Big-ration-set Process for Roving Yarn

In the big-ration-set process,as to how to remove the negative effect of the big ration set of the roving draft in conformity with the big ration set of the carding process,analysis is done to the impact of the big-ration-set process on the shift variation of draft,the duo-force,the poor distributed fiber strand and the fiber movement.Highlight is given to the big-ration-set process as to its impact on and control of the roving process,as well as the spinning process in conformity with the roving process fr...
