STUDYING THE EFFECTS OF THE WEFT DENSITY ON THE ELASTICITY OF THE STRETCH DENIM FABRIC

Abstract

The demand for using stretchy denim apparel products is huge, thanks to
the superior properties of the fabric with good elasticity and high comfort. The
paper investigated the effect of the weft density parameter on the fabric
structure, the elastic ratio in the fabric and the elasticity of the fabric in the
vertical and horizontal directions of the bi-stretch denim fabric, which has the
same ingredients of cotton core spun yarns. The higher the weft densityis, the
higher the percentage of elastic yarn in the fabricis and the better the fabric
structure stabilityis. However, not the higher the density, the better the
elasticity, the elasticity also depends on the density correlation between warp
and weft systems. This research is the scientific basis for selecting suitable textile
technology parameters for finishing processing technology and design
technology of garment products using stretchy denim fabric.
