Influence of drafting system variables at speed frame on yarn tenacity and breaking elongation using Taguchi method

Abstract

This study evaluates the impact of drafting systems and variables on yarn quality, emphasising tenacity and elongation. The study tries to determine the best drafting system setup and how spacer size and roller load affect yarn qualities. The investigation used PK 1500 3/3, 1600 4/4, and 1500 4/4 drafting systems. The front top roller load and spacer size varied for yarn samples. We examined and analysed yarn tenacity and elongation to evaluate their impacts. Statistics were used to evaluate the results and find relationships between drafting system setups and yarn quality. The PK 1500 3/3 drafting system produced the best average yarn tenacity, followed by PK 1600 4/4 and PK 1500 4/4. Spacer size had a smaller effect on tenacity than front top roller load, increasing and then decreasing with load. The 3/3 system was most affected by the front top roller load. The drafting system and overhang affected yarn elongation more than the front roller load, back roller load, and spacer size. The PK 1500 3/3 process produced the highest-breaking-elongation yarn. Lower R² results suggest ring frame specifications have a greater impact on yarn quality than roving quality. The research helps optimise drafting system settings and emphasises ring frame process parameters. The foundation for future research on textile manufacturing yarn quality factors is laid by this research.
