轻定量粗纱与成纱质量的关系

The Relationship between Light Fixed-quantity Rovingand Spinning Quality

阐述了粗纱工艺参数中定量、粗纱捻系数以及细纱后牵伸的选择。并通过试验确定 ,在原棉内在质量有所下降的情况下 ,采用轻定量粗纱能保证成纱质量 。

This article relates how to select fixed-quantity and twist in the technology parameters of roving, and back draft in the technology parameters of spun yarn. By experiment, light fixed quantity of roving is adopted under conditions of raw cotton with a little descented quality to assure spinning quality for meeting requirements of users.
