The RoCoS compact spinning system constitutes three roller roller drafting structure by means of RoCoS assembly, magnet - the principle of mechanical cluster, have been drafting, gathering and twisting of yarn. The agglomeration spinning technology RoCoS simple structure, easy to install, reliable, easy to maintain, and overcome the the traditional airflow cluster spinning the lack of technology. It is suitable for the type of spinning cotton or wool yarn can be used for a new machine or old machine is a strong market potential for the development of a new type of compact spinning technology. This paper analyzes the RoCoS spinning device design, spinning principle, the scope of the mechanical spinning of the magnet were tested and compared with the ordinary ring-spun yarn quality. The results show that the the Rocos a small investment, maintenance-free, spinning good quality spinning device. This article made experimental content in the the traditional spinning installation of RoCoS device, roving spun yarn. Article whether RoCoS device into the yarn quality comparison as well as the twist factor and back draft multiples Discussion on the single factor. Experiments: the after installation of RoCoS device, hairiness, breaking strength, breaking elongation, evenness is improved significantly. Explore drawn: is gradually reduced with the increase of the twist factor carded cotton yarn hairiness, but reaches a certain level will increase by a factor of two single. Carded hairiness subsequent zone draft multiple degree of change, the overall increasing trend in the first reduced.KeyKey words:words: spinning; RoCoS; yarn; quality; hairine目目 录录1 绪论绪论.11.1 引言.1 1.2 传统环锭纺的局限性.1 1.3 集聚纺技术.4 1.4 集聚纺纱技术的纺纱原理.6 1.5 ROCOS 集聚纺关键技术介绍.7 1.6 集聚纺纱的优点.8 1.7 集聚纺纱使用的纤维原料.92 实验准备实验准备.112.1 实验原料.11 2.2 仿制 14.5TEX单纱的工艺参数计算.11 2.3 实验仪器及改进设备装置.113 实验结果分析实验结果分析.173.1 普梳棉纱线方案与结果.17 3.2 普梳棉质量指标测试结果与分析.17 3.3 普梳棉单因子探索.184 结束语结束语.21致致 谢谢.22参考文献参考文献.
