The Rotary Rubbing Color Fastness Tester (Crockmeter) is a specialized instrument used to evaluate the colorfastness to rubbing of textiles, leather, and other materials under dry and wet friction conditions. It complies with international standards such as ISO105-X12 and AATCC8. By simulating friction during actual wear and washing, it accurately measures the degree of color transfer from the sample surface to the rubbing cloth. It is widely used in the apparel, home textiles, and leather goods industries.
