摘　　要：为了提高粗纱质量、减少粗纱纱疵,通过对新车粗纱毛羽、"老鼠条"和积花纱疵等粗纱常见问题产生的原因进行理论分析,制定出解决方案并通过实践进行生产检验,用细纱工序质量指标数据对比说明措施的效果。指出改善锭翼通道、压掌通道清洁度,更换压掌材料,采用橡胶假捻器,降低粗纱速度可以很好地减少粗纱毛羽;减小粗纱定量,增大罗拉隔距、后牵伸倍数、钳口隔距等措施可减少"老鼠条"的产生,而积花纱疵也应通过加强锭翼等粗纱通道的清洁来减少。In order to improve the roving quality with less roving fault,through the analysis of the common faults in the roving process such as roving hairiness,irregular flock and accumulation of fly,some solution is given with practice proven. The solution is proven with the spun yarn data. Conclusion is made that improvement of the flyer tunnel,and the cleanness of the pressurized staying tunnel, change of the material of the pressurized staying,appplication of the rubber false twister plus the reduction of the speed of the roving frame can markedly reduce the roving hairiness. Reduction of roving ration and increase of the roller gauge, rear draft multiply and gauge of the nipper jaws can reduce the amount of the irregular flock. The accumulation of fly and be reduced through cleaning of the flyer tunnel.
