【 摘 要 】

Elastane is used in all areas where a high degree of elasticity is required. The elastane core spun yarns are preferred to provide a better stretch for woven fabrics. In this study, it is intended to investigate the effects of elastane draw ratio on air permeability of denim woven fabrics. For this study, 29.5 Tex cotton combed ring spun yarn samples were produced with four different elastane draw ratios (3.07, 3.33, 3.63, 3.99). 3/1 Twill and 2/2 Twill denim fabric samples were woven by using the sample yarns in weft direction with three different weft densities (21, 25, 29 wefts/cm). In doing so, 24 denim fabric samples were obtained. Then air permeability of fabric samples were measured. Analysis of variance (ANOVA) was applied to determine the statistical significance of the effects of elastane draw ratio, weft sett and weave type on fabric air permeability.
