Shoelace wear-resistant tester mainly tests the degree of wear-resistant.

When test the extent of wear-resistant, shoelace device is as follows: take two shoelace, mutually hook in the middle, and form into the right, the left,.clamp the both ends of the right at the right fixture ( moving folder) of shoelace wear-resistant tester, both ends natural away from 25mm after clamping, use sample sample regulation to assist, make the right hook the left at 52.2 °,  the hooking point and the clamping point are away from 120mm, then with the left fixture to clamp the end of the left, the other side places in the pulley groove, and hang weights below. Clamping point and pulley groove are natural away from 35±5mm, when test, the moving folder does reciprocally motion with the right and left straight line at constant speed. To make two shoelace mutual friction in the middle, until the required times of friction or shoelace broken, at this time, record the number of friction.
