Study of the impact of elastane's ratio and finishing process on the mechanical properties of stretch denim

Abstract

The wear comfort desired by the consumer is leading to increased use of fabrics containing elastane filaments. However, the elastane's ratio is an important factor influencing the fabric's mechanical properties. Thus, we study the effect of elastane's ratio and finishing process on the elasticity of denim whose weft yarns are cotton covered elastane-core spun yarns having the same twist factor and various elastane's ratio.
