The GB/T 40920-2021 standard focuses on reciprocating friction colour fastness in leather colour fastness testing. It clearly stipulates the test method of leather reciprocating friction colour fastness, including technical requirements of test equipment, specific operation procedures of reciprocating friction, sample preparation and result evaluation rules. Color durability of leather is accurately evaluated by simulating the scene of frequent reciprocating friction of leather in actual use. This provides a key basis for mass control of leather products and helps enterprises to produce high-quality leather products with wear resistance and stable color.
