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。

Abstract: 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.

Key words: heavy weight; cotton carding; polyester viscose blended yarn; yarn quality; drawing; neps

“輕定量、慢速度、紧隔距、重加压”是目前传统纺纱的主要思路,但这种生产模式严重阻碍了纺纱效率的提高,且目前中国纺纱行业正面临着招工难、劳动成本高的难题[1]。因此“重定量、大牵伸”的高效纺纱工艺必将成为未来企业的选择,可充分发掘前纺工艺的潜力,提高企业的利润空间[2]。但是,这也对纺纱设备和工艺提出了更高的要求,在满足高效生产的同时,必须保证成纱质量的稳定性。陈玉峰等[3]在粗纱重定量下,对细纱工艺进行探讨,认为采用“三大三小”的工艺原则可保证细纱的高质量、高效率生产。陈玉峰[4]对粗纱重定量工艺进行了探讨,并从牵伸的各个方面分析了重定量对粗、细纱的影响。刘建林[5]通过优选梳棉机,合理配置分梳原件,在提高生产效率的同时,半制品及成纱质量也得到了一定程度的提高。……
