半精纺工艺流程及纺纱设备的选用

Semi-worsted spinning process and selection of equipment

为更好地应用半精纺工艺生产色纺纱,对几种不同组合形式的半精纺工艺流程进行分析对比,总结了其优缺点。通过试验,分析主要生产设备的结构性能和形式对半制品或成纱质量的影响,提出在应用不同生产工艺流程和设备过程中应注意的问题,并指出半精纺纺纱工艺对纺纱专件、生产管理等方面的要求。同时,还介绍了新型纺纱技术在改造传统环锭细纱机及开发半精纺新产品方面的应用,可为合理选用半精纺设备和进一步开发纺纱设备提供参考。

In order to better apply the semi-worsted spinning process for production of colored spun yarn,the paper made an analytical comparison of several forms of semi-worsted process,summing up their advantages and disadvantages.The impact of the structure and performance of the machine on the quality of semi-finished product or yarn was investigated,precautions were given for using different production processes and equipments,along with the requirement on individual equipment and management in respect of semi-worsted spinning.Moreover,application of novel spinning technologies to the innovation of the traditional ring spinning frame and development of semi-worsted products was introduced.This paper has provided a reference for rational selection of semi-worsted spinning equipment and further development of the spinning equipments.
