Fastness Rotary Friction Tester

A Fastness Rotary Friction Tester, also known as a Rotary Crock meter, is a specialized instrument used to evaluate the color fastness of textiles and materials when subjected to rotational rubbing. This test simulates the wear and friction that fabrics experience during use, helping manufacturers assess the durability of dyes and finishes. Purpose of Fastness Rotary Friction Tester The primary function of the Fastness Rotary Friction Tester is to determine how well a fabric's color withstands rubbing, both in dry and wet conditions. This is crucial for ensuring the longevity and appearance of textiles in real-world applications, such as clothing, upholstery, and footwear. Working Principle of Fastness Rotary Friction Tester The tester operates by applying a specified pressure to a fabric sample using a standardized rubbing finger covered with a test cloth.
