This instrument is used for leather surface friction Fastness is tested by determining the “fading” and the degree of staining of wool felt to evaluate the color transfer. During the test, wrap dry or wet white wool felt on the friction surface, and then reciprocate the friction on the test piece clamped on the test bench. There are two test methods, dry and wet. nmtTextile Testing Instruments, Testing Equipment Manufacturer
