Effects of Sled Velocity on Fabric Friction

The influence of velocity of sliding on some new frictional parameters of weft pile fabrics is reported. The frictional amplitude diminish as the velocity of motion increased. The kinetic frictional resistance also diminish initially, and then increased as the velocity of sliding increased. The initial decrease in resistance to motion is attributed to viscoelastic effects while the increase in resistance to motion at higher speeds is ascribed to mechanical interlocking of surface structure. The amplitude of frictional resistance and number of peaks are shown to be related to some partinent fabric properties such as cord height and number respectively.
