GB/T 7075-1997 specifies the test method for the colour fastness of Spinning & weaving products to alkali cooking. The standard specifies the equipment required for the test, the configuration and concentration requirements of the alkali solution, and details the operation process of Spinning & weaving products to alkali cooking, such as temperature, duration control, etc. It also formulates scientific results evaluation criteria. Testing according to this standard can accurately measure the color retention ability of Spinning & weaving products after alkali cooking treatment. It provides a key basis for Spinning & weaving enterprises in Product Research & Development, production process adjustment and mass control to ensure that the color fastness of the products under relevant processing or use conditions meets the standard.
