Abstract

This study aims to analyze the effect of twist ratio on the mechanical properties of ply yarn, including tensile strength, tenacity, and elongation at break. A controlled quantitative experimental approach was employed using staple yarn composed of 65% pineapple leaf fiber (PALF) and 35% cotton, with two yarn counts (Ne 14.56 and Ne 19.50) and twist ratio variations ranging from 0.34 to 0.76. Tensile testing was conducted with 25 repetitions for each variation, and the data were analyzed using two-way ANOVA and linear regression. The results indicate that increasing the twist ratio significantly improves tensile strength, tenacity, and elongation at break for both yarn types. ANOVA results show that twist ratio and its interaction with yarn count have a highly significant effect on tenacity and elongation (p 0.0001), while yarn count does not significantly affect elongation independently. Linear regression analysis reveals a strong positive relationship with high coefficients of determination (R² 0.79). No over-twist condition was observed within the studied range, indicating that a twist ratio up to 0.75 remains effective in enhancing mechanical properties. These findings highlight that twist ratio functions not only as a process parameter but also as a structural design variable for optimizing the mechanical performance of natural fiberbased ply yarns.
