6 Rieter. Kahatex COMFORSPIN MACHINES Production of high-competitive yarn COMFORSPIN MACHINE K 44 The ComforSpin machine K 44 from Rieter has been convincing the customers by high quality and reliability for many years. More than 1 Mio spindles are successfully producing worldwide. The K 44 is based on the proven G 33 ring spinning machine and equipped with advanced compacting technology consisting of direct driven, wear-free perforated drum, suction insert and air guide element. The fibers are condensed by an air current created by a vacuum in the perforated drum. They are fully controlled by an air stream all the way from the nip after the drafting zone to the spinning triangle. The resulting fiber condensation reduces the spinning triangle to a minimum and eliminates fiber loss at this point. Most important features of the K 44 are: SERVOgrip for doffing without underwinding FLEXIdraft push-button setting of main draft and yarn twist without gear changes ROBOdoff reliable doffing in less than 2 min ROBOload fully automated, reliable and rapid cops removal and tube loading system MACHINERY INSTALLED 34 K 44 ComforSpin machines with 1 008 spindles each are in operation and a further 14 K 44 with 1 008 and 24 K 44 with 1 200 spindles will be installed in the near future giving 77 184 spindles in total.
Rieter. Kahatex 7 COM4 COMPACT YARN Innovative yarn character TOUCH THE FUTURE WITH COM4 YARNS To be successful in the market, Kahatex focuses on spinning and processing exclusively compact yarns. The made investment pays off in advantages in productivity of both the spinning and the knitting/weaving machines. A total of 34 272 Rieter COM4 spindles have been installed since 2005. That Kahatex consciously decided for ComforSpin machines K 44 from Rieter shows trust in the continuous improvements and the running performance. PROPERTIES OF COM4 YARNS The perfect yarn structure and the high economic efficiency of the ComforSpin technology are the reasons behind the striking success of COM4 yarns. Controlled, intensive compacting of all fibers substantially reduces the number of protruding fibers. A higher utilization of the fibrous material results in a higher yarn tenacity, the reduced hairiness in better running properties. ADVANTAGES OF COM4 YARNS Low level of yarn breaks during processing High efficiency of the production machinery Cost reduction for sizing and de-sizing Elimination of singeing Reduced fiber abrasion means less pilling tendency Reduced fiber fly means less foreign fiber contamination Clear structure of patterns Rieter is convinced by the success of COM4 yarns, as well as Kahatex is. The increasing market share of COM4 yarns worldwide is proof for a bright future. A distinct improvement in yarn uniformity and less weak places in the yarn are decisive advantages for spinning mills and downstream processors. Compact yarns enable numerous optimizations to be made during all processing stages. Since the market launch of the first ComforSpin machine in 1999, Rieter has been supporting its customers in spinning and processing COM4 yarns. Many textile technologists analyzed the impact of the new yarn structure in the following processing stages. Thus Rieter is able to support its customers also with knitting, weaving and finishing compact yarns.
