The Impact of Machine and Construction Settings on Sliver and Yarn Quality in Ring Spinning Process

Abstract

Ring spinning is the most important spinning system with its wide application area, high yarn quality and widespread usage in staple fiber spinning. Each parameter in the long process steps in the ring spinning system significantly influences the yarn quality. Within the scope of this study, the effects of the machine and construction settings on the sliver and yarn properties in each of the blowroom, carding, drawing, combing, roving and spinning processes are examined. In this context, the effect of many parameters such as carding parameters, sleeve type and size, combing type, yarn drawing and twisting settings on the quality characteristics of slivers and yarns have been observed. The effects of setting changes were investigated by examining the whole production process of cotton ring yarns with different yarn count and twisting properties. Breaking strength and elongation at break properties and hairiness, unevenness and imperfections of the materials were analyzed. The actual yarn manufacturing in the ring spinning mill was examined and the relations between production and quality were determined. It is thought that the results obtained will be useful for field studies and scientific researches related to ring yarn spinning
