This study investigates the relationship between fabric twist level and its relative elongation index across various textile structures. Samples of cotton, polyester, and blended fabrics with systematically varied twist multipliers (from 3.2 to 5.8 twist/cm) were subjected to standardized tensile testing according to ISO 13934-1. Statistical analysis confirmed a significant inverse correlation (r = −0.87, p < 0.001) between twist intensity and elongation at break, while yarn count and fiber composition moderated this effect. The results demonstrated that fabrics with lower twist values (3.2–3.8 twist/cm) exhibited 18–24% higher relative elongation compared to highly twisted counterparts. These findings provide practical guidelines for optimizing fabric mechanical properties in garment manufacturing.
