细纱压力棒隔距块的应用实践

Application Practice of Spacer with Press Bar in Spinning Process

介绍了细纱压力棒隔距块的特点和应用机理,工艺方面采取加大后区牵伸倍数,加大后区罗拉隔距,减少粗纱捻系数的"两大一小"工艺措施;加强设备维修,加大操作管理力度,合理的温湿度管理控制措施;能够有效控制管间CVb值差异、毛羽数量以及牵伸不开出硬头的问题,达到降低条干CV值,提高成纱质量的目的。

Introduction is made the spacer with press bar regarding the specification and the application theory. It is necessary to do the following：increase of multiple of draft in the rear area, reinforcement of the operation management plus proper humiture control for effective control of the CVb difference between bobbins and reduction of hairiness and hard draft,so as to reach the aim of reduction of CV value and upgrading yarn quality.
