|Abstract:||Effect of three crucial parameters of splicing, exclusively related to retwisting operation of splicing, namely air pressure, retwisting time and overlapping length on retained splice strength (RSS) has been studied. During this study, the parameters related to untwisting are kept constant based on the visual untwisting performance. Three-factor three-level Box-Behnken design is employed on three different cotton yarn counts (20s Ne, 40s Ne and 60s Ne), produced by ring spinning. Interactive effects of parameters have also been analyzed through contour plots and optimization conditions are achieved using the statistical software called Minitab. The optimization conditions can be used as a guide to set the splicer parameters. It is observed that average retained splice strength of the yarn increases with the increase in yarn count. Higher RSS can be obtained with the combination of lower compressed air pressure with relatively higher retwisting time.|
