摘要
为了克服传统铁板上销的弊端,合理选用性能优良的细纱上销,分析了目前细纱机牵伸的主要型式及牵伸后区附加压力棒上销对成纱质量的影响情况,通过应用曲线牵伸上销与普通上销纺T/C 14.7 tex纱的成纱条干、千米节结对比,说明使用后区附加压力棒上销,可以降低成纱条干CV值、减少粗、细节,再配以合理的后罗拉隔距,后区牵伸倍数等工艺参数,可进一步提高纺纱功效及成纱质量。
In order to avoid the disadvantages of the conventional top cradle and to optimize the top cradle with excellent performance for spinning process, analysis is done to the main drafting types in use and the impact of the rear area of drafting section with press bar on quality of yarn. Comparison analysis of the curved drafting top cradle and the normal top cradle in spinning yarn T/C 14.7 tex regarding eveness,neps in 1 000 meters proves that application of top cradle with press bar in rear area can reduce CV value, slubs and snicks. Proper configuration of rear roller space and drafting multiply can further improve spinning property and spinning quality.
