Resolution of the stick-slip friction traces of fabrics

Some new frictional parameters of fabrics determined by the trace analysis of their stick-slip friction property is reported. Both scouring and mercerization processes induce structural consolidation which in turn can increase the frictional resistance, number, amplitudes of the stick-slip, and the differential frictional forces of the fabrics. This result is ascribed to an increase in the crimp propensity of yarns. The magnitudes of the frictional parameters of weft pile fabrics are correlated with the numerical estimates of the tactile stimuli of their surface roughness. A good linear relation exists between the values of objective and subjective roughness of fabrics on a logarithmic scale.
