Performance of Core & Dual-core Cotton Yarn Structures on Denim Fabrics

Abstract

ABSTRACT Elastic structures are opted in denim fabrics to increase elasticity and recovery properties of fabrics as well as comfort properties. In this study, performance properties of denim fabrics were evaluated comparatively as tensile strength, tearing strength, air permeability, mass change, dimensional stability, seam slippage, fabric growth, and stretchability. 100% cotton, core-spun and dual-core spun yarns (Ne 16/1) used at weft direction of denim fabrics. 100% cotton ring spun yarns (Ne 13.5/1) were used as warp yarns at all produced three denim fabrics. All the test results were measured numerically and evaluated statistically with one-way analysis of variance (ANOVA). There was significant difference found among fabrics for the variation of weft yarn structures from the statistical evaluation. The impact of varying washing processes on the stretch and growth (%) of denim fabrics was also revealed. Core-spun yarn containing denim fabric showed more growth and stretch percentage in all forms of washing processes. It was also found that packing density of yarns had a significant effect on air permeability of fabrics.
