Rubbing Fastness Tester mainly uses a sample holder to fix the sample and sandpaper on one side of the base. Shake the handle to make the friction head with white cotton cloth reciprocate on the sample with a specified stroke. After rubbing ten times, observe and compare and evaluate with a gray card. The degree of sticky color on the white cotton cloth judges the dyeing of the fabric sample or the stability of the surface coating, and provides reference data for the evaluation and selection of materials.
