Studies performed in recent years have shown that the spinning triangle in conventional ring spinning has a noticeable effect on the yarn surface (hairiness), yarn strength, yarn elasticity, processing performance and fly formation [1]. Therefore, new researches were concentrated on decreasing the spinning triangle [2]. As a result of these studies, a new spinning system has been developed called compact spinning, which decreases the yarn hairiness to a great extent [3].Compact spinning, which is a new version of ring spinning, produces a new yarn structure as the edge fibers are incorporated into yarn due to the minimization or elimination of the spinning triangle, and the harmful effects of the spinning triangle on yarn characteristics are eliminated [4]. The most apparent features of these yarns are their high strength and elongation values, and low hairiness [5][6][7]. Compact spinning also attempts to reduce fly liberation during conventional ring spinning by using pneumatic compression [8]. When using compact yarns in the knitting process, the practical applications offer some advantages such as decrease in abrasion, dust and fly, thus decreasing the cleaning costs, less needle breakages, and less fabric faults [9]. 1 In this study, different knitted structures were produced with compact and conventional ring yarns. The physical properties of fabrics were evaluated before and after the pre-treatment and dyeing processes and compared with each other statistically.Abstract This study investigated the differences between knitted fabrics made from compact and conventional ring-spun yarns. 100% cotton yarns, produced from the same cotton blend, were spun according to compact and conventional ring spinning principles in two different yarn counts and twist factors. Three different knitting structures, i.e., interlock, rib and single jersey, were produced from these yarns. The physical properties of these fabrics were investigated and compared with each other before and after the reactive dyeing process. When the results were examined, it was found that the hairiness of compact yarns was less and the strength and elongation percentages were higher, the fabrics produced with compact yarns showed less tendency to pilling and had a higher bursting strength. No statistical differences were observed with regard to spirality, weight, abrasion resistance, color efficiency and rubbing fastness of the fabrics produced with compact and ring-spun yarns.
