GB/T 18886-2002 is the test standard for the resistance of Spinning & weaving products to saliva colour fastness. The standard specifies the method for testing the colour fastness of Spinning & weaving products in a simulated saliva environment, covering the equipment required for the test, the preparation of simulated saliva, and the specific operation procedures of Spinning & weaving products in contact with saliva, including contact time, temperature and other key conditions. At the same time, rules for evaluating the grade of colour fastness are formulated. According to this standard test, the Color Stability of Spinning & weaving products under the action of saliva can be accurately judged, which is of great significance to ensure the safety and mass of Spinning & weaving products, especially for infants and special groups.
