Abstract :
In this part of series, the effects of a number of structural and productional factors on dynamic friction in the fabric surface and fabric appearance are examined . The factors are yarn type spun by different spinning systems, such as air-jet, core spun, combed, open-end, carded and fabrics woven by shuttle loom and air-jet loom. Friction tests have been conducted using techniques that allow measurments along the warp and weft direction using autospectral density function. The spatial construction of the fabric surface has been evaluated using image processing techniques. The results show that warp protruding yarns lie down obliquely on the fabric surface at an angle of to the warp direction in a counter clockwise direction and appear as oblique lines in the fabric surface woven by an air-jet loom. The protruding yarn density obtained by image processing techniques using fourier transform analysis correlates with those from spectral analysis of dynamic friction in the fabric surface.
