HG/T 5665-2019 "Spinning & weaving dyeing and finishing aids Coating printing gluing agents, determination of printing friction resistance colour fastness" standard specifies the determination method of printing friction resistance colour fastness of Coating printing gluing agents in Spinning & weaving dyeing and finishing aids. This standard is applicable to evaluate the friction resistance performance of Coating printing gluing agents during the printing process of Spinning & weaving products. The testing process includes preparing Coating printing colorants, printing samples, performing friction resistance tests after specific stoving treatments, and determining the friction resistance colour fastness grade of the printed fabric according to the test results. The purpose of this standard is to ensure that the performance of Coating printing gluing agent meets the requirements, providing technical support and mass assurance for Spinning & weaving printing processing.
