The Electric Crocking Tester – GenCrock is designed to evaluate the colorfastness of fabric and leather materials by testing their resistance to dye transfer under both dry and wet conditions. This test method assesses how much dye from the material transfers to another surface when rubbed, indicating how well the color withstands friction or abrasion.

During the test, a specimen is securely fastened to the base of the machine, where it is rubbed with an abrasive hammer equipped with either a dry or wet cloth. The GenCrock then measures the degree of color transfer to the cloth, which is rated to determine dye quality.

This tester is a necessity in industries like textiles and leather manufacturing, where product quality depends on color durability. By simulating everyday wear conditions, GenCrock helps manufacturers guarantee that materials maintain their appearance and color integrity over time.
