纯棉0.84 tex纱的研制要点

Key Point on the Development of 0.84 tex Yarn Spinning

介绍纯棉特细号纱线的研制过程。总结了3.47tex×2、1.79tex×3和0.84tex×6三种特细号纱的生产技术要点,如高品质棉花供应及选配、大牵伸的实现及成纱质量改善、引入水溶性维纶纺纱后处理等问题的解决方法和工艺流程优化。指出:采用双粗纱流程并采用两个头道粗纱并行喂入解决牵伸与不匀之间的矛盾,使用自育优质新疆长绒棉,发明可变周长的染纱管等技术措施使特细号纱线不断取得进展和突破。认为新技术的应用是推动产品创新的关键。

The development procedure for pure cotton super fine yarn was introduced.The production key points for three super fine yarn including 3.47 tex×2,1.79 tex×3 and 0.84 tex×6 were summarized,for examples the solution for issues like supply and selection of higher quality cotton,achievement of larger draft,yarn quality improvement,post treatment after adding water solubility vinylon fiber together with the optimization of process flow.It was pointed out that continuous progress and breakthrough of super fine yarn spinning were achieved by taking the technology measures like adopting double roving procedure together with the feeding of two first roving at the same time to solve the contradiction between drafting and unevenness,selecting self-cultivated Xinjiang long stapled cotton,inventing yarn dying tube with changeable perimeter etc..It is considered that the application of new technology is the key to promote product innovation.
