The GB/T 42223-2022 standard focuses on the Gakushin method for the friction resistance colour fastness of Spinning & weaving products. The standard specifies the process of testing the friction resistance colour fastness of Spinning & weaving products using the Gakushin method in detail, covering test equipment, operating specifications, sample preparation and result evaluation. This method accurately evaluates the ability of Spinning & weaving products to resist friction fading by simulating specific friction scenarios. It provides a scientific and targeted detection method for the Spinning & weaving industry, helps enterprises control product mass, and ensures the color and luster Stability of Spinning & weaving products in daily friction use.
