- The surface friction property changes of nonwovens under repetitive abrasions were observed. Surface data were acquired using a threedimensional noncontact camera and fractal dimensions were calculated to evaluate surface roughness. The fractal dimension showed a tendency to
increase with the number of abrasions. They were compared with surface friction values measured by the KES-FB system [Textile Res. J. 58(3), 129–136,1988]. Pilling on the nonwoven surface prohibited accurate surface roughness measurement, so they were detected using high-pass filtering of the surface
data. The method needs instant measurement
time and is highly objective, and therefore it is suitable for real-time on-line manufacturing systems.
