GB/T 33283-2016 is the colour fastness test standard for Spinning & weaving products, focusing on the colour fastness of industrial washing resistance. The standard specifies the test method for the colour fastness of Spinning & weaving products under industrial washing conditions, and specifies the industrial washing process, detergent use, washing equipment parameters, etc. By simulating real industrial washing scenarios, the Color Stability of Spinning & weaving products is accurately detected. This provides the basis for mass control of Spinning & weaving products related to industrial washing, enabling enterprises to produce products that can withstand frequent industrial washing and maintain color to meet specific market needs.
