摘要
通过应用压力棒隔距块和普通压力棒的对比试验,介绍平面牵伸前区使用压力棒隔距块,V型牵伸使用压力棒上销纺纱机理及在实际生产中的应用,指出要针对不同的牵伸型式合理运用粗纱捻系数,使其与粗纱定量及细纱后区牵伸倍数有机结合,才能保证前纺重定量、细纱大牵伸工艺顺利上车、纺出高品质的纱,才能有效控制生产成本、降低机物料消耗。
Comparative analysis is done of the spinning process with addtion of the press block and the conventional press bar. Introduction is done to the spinning philosophy of the processes with addition of press bar in the plain draft area and the addition of top apron cradle in the V-shaped draft process. Conclusion is made that proper adjustment is needed for varieties of draft forms. Proper roving twisting factor is needed in conjunction with the roving ration and draft multiply in the rear area for smooth operation with heavy ration in fore-spinning and big draft in rear area,consequently with quality yarn and lower cost of production.
