Investigation of tensile resilience properties of stretch denim fabrics
The aim of this research is to investigate the resilience properties of stretch denim fabrics on the basis of tensile properties and structural parameters. Tensile properties are studied using the KES-F system. It is found that for better tensile recovery stretch denim fabrics should have higher polyester and lower cotton content, lower linear density and density of weft yarns but higher density of warp yarns. Tensile resilience could be determined from the initial region of the tensile curve and by setting specific modulus of elasticity at the yield point strain. Higher specific modulus of elasticity of fabrics with elastane ensures better tensile elastic recovery.
