The standard clearly stipulates the requirements for the degumming resistance colour fastness test, covering the scope of applicable Spinning & weaving products, the specific methods of degumming treatment, the equipment and reagents required for the test, and the strict result evaluation process. By testing according to this standard, the Color Stability of Spinning & weaving products after the degumming process can be accurately judged, which provides a reliable basis for Spinning & weaving enterprises to control product mass and optimize the degumming process. It is of great significance to ensure the quality and market competitiveness of Spinning & weaving products.
