Effect of some yarn properties on surface roughness and friction behavior of woven structures

This paper focused on the effect of some constructional parameters of woven fabrics on surface roughness and on fabric-to-fabric friction coefficients. Fabrics under test differed from each other in their weft yarn counts, weft yarn properties and weft yarn density. Seven surface roughness parameters and static and kinetic coefficients of friction were assessed according to the changes in fabric constructional properties. The results showed that roughness parameters of amplitude, spacing and hybridity changed in different manners in the measurement directions of warp, weft and diagonal. Static and kinetic coefficients of friction changed with surface roughness values in opposite ways in warp and weft directions. Experimental results were also assessed with fabric thickness and fabric balance values. The anisotropic structure of textile surfaces was discussed by the changes in roughness parameters and friction coefficients. Skewness and kurtosis, being roughness parameters, were found to be important in the discussion of the relation between surface roughness and friction coefficients.
