The objective of this study was to investigate the differences and similarities between human-perceived fabric stretchability and the mechanical property values of fabrics, considering weave, knitting, and other structural variations and materials. Therefore, we created an elasticity scale based on mechanical properties and calculated a numerical elasticity evaluation of fabrics as stretching sensation of fabric (SSF) by comparing the elasticity of several fabrics with different fibers, structures, and yarn thicknesses. The relationship between these factors and the mechanical properties influencing fabric stretchability, as well as the impact of fabric structure and material on perceived stretchability, were analyzed. Results indicated that sensory texture perception differed between machine measurements and human evaluations, depending on the weaving and knitting methods. Additionally, distinct trends were observed between woven and knitted fabrics based on fiber type, which significantly influenced stretchability assessments.
