Rotary rubbing color fastness tester Working Principle‌:
Under controlled pressure conditions, the device performs dry or wet rubbing cycles using circular wool felt. Testing automatically terminates upon reaching the preset friction count. Fastness assessment is conducted by analyzing sample material degradation or color transfer to the rubbing pad, with results compared against a standard gray scale for accuracy.
