The Electric Crocking Tester – GenCrock performs colorfastness testing by simulating rubbing on fabric or leather specimens. In this process, the specimen is securely fastened to the base of the crocking meter, where it is subjected to friction from an abrasive hammer equipped with either a dry or wet cloth, depending on the test requirements.

Under controlled conditions, the hammer rubs against the material, causing dye from the specimen to transfer to the cloth, simulating real-world wear conditions. After the test, the degree of color transfer is measured using a rating scale, which helps determine the dyeing grade and durability of the material’s color. This method provides valuable insight into how well a material will maintain its appearance when subjected to friction, thus allowing textiles and leather products to maintain their quality.
