Analysis of the Performance of Sewing Threads Manufactured from Conventional and Compact Ring - spun Yarns

distinctive features of compact yarns. The basic alteration in the compact spinning system, which is the modified form of the ring spinning system, is that the drawing system of compact spinning machine finishes with a condensation zone formed with the aid of air suction. In this way, the spinning triangle is eliminated, which is at the same time the strongest and weakest feature of ring spinning with regard to other systems; thus a better orientation of fibres in the yarn is achieved. Various machine suppliers use different designs of the condensation zone as a result of the elimination of the spinning triangle [13].
