绒线生产中粗纱质量的控制

Quality control on Roving in Knitting Wool Production

提高粗纱质量的重点是降低纱的重量不匀率，提高粗纱条干的均匀度。为此，在实际生产中应做到：制订合理的工艺；加强保全保养工作，保持良好机械状态；加强技术管理，健全运转操作和检查考核制度。

The key to improve roving quality lies in reducing weight unevenness and improving yarn evenness. To reach this goal, the article suggests to map out rational process; reinforce maintenance work, so as to keep the machinery in good condition; strengthen technical management and amplify rules and regulations on operation and inspection.
