Device for measurement of friction coefficient for textile fiber, yarn, threads has a rotary shaft with placed uniformly and in parallel at its one end textile fiber, drive of the shaft and torsion weight. At the other end of the shaft a bobbin is fixed, with textile fiber winded on it in several rows, turn to turn, it is surrounded by fiber with weights fixed at its ends. At that fiber at arc of going around by 180° is placed into a groove that is formed with surfaces of neighboring turns of fiber winded to the bobbin. |
