A RESEARCH ON DETERMINING OPTIMUM SPLICING METHOD IN TERMS OF FIBER TYPES AND YARN COUNT

Abstract

The quality of the splice made in the yarn is very important in terms of final yarn performance. The yarn ends are not spliced well; the yarn breaking strength and elongation are reduced, resulting in too many breaks in the machines during fabric production and consequently low yield. Many methods, which are pneumatic method, the mechanical method, the pneu-mechanical method and electrostatic method, are used for splicing. Among them, pneumatic splicing is the most popular. In this study, it was aimed to investigate spliced yarn performances in terms of three types of splicing methods including air splicing, wet splicing and mechanical splicing known as twin splicing, and to reveal optimum splicing method in terms of fiber type and yarn count. For this aim, a total of twenty seven ring yarns as pure and blended containing different raw materials, which are cotton, viscose, polyester, modal and acrylic, were produced with different yarn counts having Ne 20, Ne 30 and Ne 40. The obtained yarn samples were spliced in different splicers including air splicer, wet splicer, and twin splicer on Savio Polar IDLS winding machine. The strength and elongation values of spliced yarns were measured with Mesdan-Lab Splice Scanner-3. The measurements were compared to each other and the values before splicing. The study results revealed that twin splicer is the best for cotton fiber and acrylic fiber, whereas it is the worst for regenerated cellulosic fibers, all splicer types can be used for polyester fiber, and the best splicer type is air splicer for fine yarns whereas it is twin splicer for coarse yarns.
