The pact spinning system constitutes three roller roller drafting structure by means of RoCoS assembly, - 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 e 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 isa strong market potential for the development of a new type pact spinning technology. This paper analyzes the RoCoS spinning device design, spinning principle, the scope of the mechanical spinning of the were tested pared 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 parison 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 reduce
