GB/T 5716-2013 specifies the test standard for the colour fastness of Spinning & weaving products to alkali spots. The standard clarifies the preparation requirements of test equipment and alkali solution, and elaborates the operation process of Spinning & weaving products in contact with alkali spots, such as alkali solution concentration, action time, temperature and other key conditions. By comparing the changes of Spinning & weaving products before and after contact with alkali spots, the colour fastness grade is assessed according to the standard sample card. According to this standard test, the Color Stability of Spinning & weaving products under the action of alkali spots can be accurately judged, which provides a key basis for Spinning & weaving enterprises to control the mass of products and deal with the application scenarios of alkali-containing environments, and helps to improve the applicability of products under relevant conditions.
