1、K45紧密纺细纱机论文：紧密纺特细号耐磨棉纱的工艺技术研究及产品开发【中文摘要】随着人们生活水平的提高和生活节奏的加快，人们对服装面料的要求亦越来越高，轻薄、合身、舒适、柔软、弹性已经成为服装面料追求的新目标之一，纯棉产品向高档产品发展将是一种必然趋势。紧密纺高支纱能提高织物表面的光洁度、清晰度和滑爽度，改善织物的外观，因此优质的纯棉紧密纺高支纱产品开发将有广阔的市场前景。本文在总结紧密纺纱成纱质量优越性的基础上，利用国际领先的瑞士立达紧密纺纱生产线开发高支耐磨纯棉纱，研究开发了7.3tex和9.7tex纯棉紧密纺精梳纱线，对紧密纺纱的前纺工序工艺设计过程及工艺特点进行了详尽的叙述。本文除了分

2、析K45紧密纺集聚纺纱原理及相应的紧密纺装置、紧密纺特有的关键件及紧密纺纱工艺过程外，研究了K45紧密纺细纱机工艺参数（如负压大小、细纱捻系数、后区牵伸倍数等）对紧密纺成纱质量的影响，利用单因素分析方法，分析了不同的工艺参数对纱线性能影响的规律及原因，为生产实践奠定了基础。应用正交试验对集聚负压大小、细纱捻系数、后区牵伸倍数这三个工艺参数进行了优化处理，并应用极差分析法及方差分析法对试验数据进行处理，得到了成纱综合性能最优的工艺参数。其结果表明了集聚负压大小对成纱质量的影响较大，后区牵伸倍数和细纱捻系数次之。纺制7.3tex纯棉紧密纺精梳纱线的最优工艺参数为：负压为2500Pa，细纱捻系数为4

3、00，后区牵伸倍数为1.09。用光学显微镜，并在计算机辅助下观察用相同粗纱纺制得到的紧密纺纱线和普通环锭纺纱线的纵向和横向结构，并对纱线耐磨性、成纱强力及毛羽等性能与普通环锭纺纱线进行了分析对比。并利用origin8.0分析软件对成纱条干、成纱细节与成纱强力的试验数据进行了回归分析，找出了两者之间的多项回归方程结果表明成纱细节对成纱强力的影响非常大。【英文摘要】With the improvement of people living, requirements people have on fabric becomeincreasingly strict, Light, fit, comfo
