Background: The drafting system configuration in speed frames significantly influences the quality ofspun yarn. Factors such as yarn irregularity, coefficient of variation (CV %), imperfections, and hairinessare crucial parameters for evaluating yarn quality. This study compares the performance of PK 1500and PK 1600 drafting systems with 3-over-3 and 4-over-4 configurations using Taguchi methods tooptimize drafting variables for better yarn uniformity and reduced hairiness.Methodology: The study analyzed the effects of front and back top roller pressure, spacer size, andoverhang in the drafting region for PK 1500 (3/3 and 4/4) and PK 1600 (4/4) systems. Taguchi designand analysis of variance (ANOVA) were employed to evaluate the impact of these variables on yarnproperties, including irregularity, CV%, imperfections, and hairiness.Results: The 3-over-3 configuration of the PK 1500 drafting system outperformed the 4-over-4 setups inproducing yarn with lower unevenness, reduced CV%, and fewer imperfections. Additionally, thehairiness was found to be significantly higher in yarns produced with the 4-over-4 configurations of bothPK 1500 and PK 1600 systems.Conclusion: The study concluded that the 3-over-3 drafting system in the PK 1500 configuration offerssuperior yarn quality for the tested material and machine settings. This configuration is recommendedfor achieving optimal yarn uniformity and minimized hairiness, highlighting its advantages over 4-over4 setups.
