A study has been attempted to deal with a comparison of compact yarn characteristics spun from three different commercial compact spinning systems namely Rieter's Com4 spin, Suessen's EliTe, LMW's RoCoS, and LMW's non-compact systems. In this study, we have compared the properties such as hairiness, imperfections, tenacity and elongation values of the yarns produced from the same back process material by the four systems separately for three counts Tex 14.76, 9.22 and 7.38( 40s,64s,80s Ne respectively). Project work study concludes that each system has its own unique principle and methods with optimized process parameters. From the trial taken we conclude that Com4 yarn manufacturing system results in better yarn strength, Evenness percentage, Whereas Elite yarn gives better results in hairiness and RoCos yarn gives better results in elongation percentage (in Tex 14.76) than other systems.

For several decades, developments efforts in ring spinning were focused on improving the existing technology and incorporating automation and process linking capabilities. The first compact spinning machine was put into trial production in 1995 in some spinning mills in Switzerland. For the short staple spun yarns, low yarn hairiness was felt as the most desired property. Because, this property has given certain fullness for the fabric made out of it resulting in good warmth. The technological developments that had taken place in weaving and knitting process during the past few decades to achieve higher productivity demanded high tenacity and less hairy high performance yarns. This has resulted in the innovation of new yarn by name "Compact Yarn" in the short staple spinning system.
