Abstract

Compact spinning system is simply the modification of conventional ring-spinning Compact yarn compared with classical yarn was characterized by better properties. This paper presents an analysis and comparison of the parameters of compact yarn spun on Rieter K44 (com4 spin) compact spinning frame and on Rieter GS1 conventional ring spinning frame. Combed yarn Ne 60 yarns were produced with different levels of single twist factor for each system. Also each single yarn was plied on 3 plys taking different levels of ply twist factor, By increasing ply twist factor, plied yarn properties changes by increase or decrease after a ratio between ply and single twist factor of 1.1. With a twist ratio of ply twist factor to single twist factor over 1.1, maximum strength was achieved. Compact yam with a low single twist factor and medium ply twist factor can be used instead of conventional yarn with a medium single twist factor and High ply twist factor and will be better in all characteristics and as well as higher spinning productivity.
