Investigation of the Friction Coefficients and Surface Roughness Properties of Denim Fabrics after Abrasion

The abrasion behavior of denim fabrics could be affected by fabric surface properties (surface friction coefficient and roughness) depending on fabric structural parameters. This work aimed to investigated the friction coefficients and surface roughness properties of denim fabrics woven with different structural parameters after abrasion. In general, while the abrasion process reduced the fabric friction coefficients during the initial abrasion cycles, the surface's friction coefficient increased as the number of abrasion cycles increased. However, due to the increased abrasion cycles, there was a steady decline in the roughness values of the fabric surfaces. Denim fabrics were woven with a 3/1 twill weave pattern. When the effect of the fabric structural parameters on fabric friction coefficient and roughness values were evaluated, the yarn count (Nm), yarn density, and fabric cover factor showed negative correlation coefficients. In contrast, the thickness, unit weight, and bulk density of fabric showed positive correlation coefficients.
