摘　　要：重定量工艺可提高车间生产效率,减少前纺用工与机台数量,降低生产成本,极大增强其在纺织行业的竞争力。梳棉重定量更是与纤维梳理度和最终成纱质量息息相关。文章通过增加梳棉的生条定量,并在并条工序中加大牵伸倍数,调整了熟条定量,优化了相关工序。采用相同工艺纺制涤纶/环保黏胶(65/35)18.5 tex混纺纱,对比轻、重梳棉定量对成纱质量的影响并进行分析。实验结果表明,梳棉定量适量提高可降低棉结,提高纱线综合质量。The heavy weight process can improve workshop production efficiency,cut down the number of pre-spinning workers and machines,reduce production costs,thus prominently enhancing the competitiveness in the textile industry.Heavy weight cotton carding is closely associated with the fiber carding degree and final yarn quality.In this paper,by increasing the weight of carded sliver,enlarging the draft ratio in the drawing process,the weight of drawn silver was adjusted and the related process was optimized.The polyester/environmental adhesive(65/35)18.5 tex blended yarn was spun by the same process,and the influence of light and heavy weight cotton carding on yarn quality was compared and analyzed in this article.The results show that the appropriate increase of the weight of cotton carding can reduce the neps and improve the comprehensive quality of the yarns.
