In order to measure the friction force between woven fabric and skin at a wet condition, it was proposed
that the completed wetting woven fabric could be hung on the line for different times to reach the different
wet conditions. According to the water loss characteristic of woven fabric, the relative hanging time was
used to describe the different wetting rates. The friction curves between 20 kinds of woven fabric and
human skin were measured by the independently developed fabric-skin friction tester at 6 kinds of wet
conditions. It was found that there were 4 kinds of friction-sliding displacement curves. They were
normal friction curve, arched friction curve, rising friction curve and decline friction curve. According
to the characteristic of various friction curves, 7 kinds of friction indices were defined to characterize the
friction properties between woven fabric and skin at wet conditions. They were static friction, turning
point between static friction and dynamic friction, average dynamic friction and its coefficient of mean
deviation, maximum dynamic friction force, variation rate of dynamic friction and friction coefficient.
Besides, it was also found that normal friction curve and rising friction curve usually occurred and their
appearing probabilities were 44% and 47%, respectively.
