GB/T 2397-2012 "Disperse Dyes - Determination of Build-up" is applicable to the determination of the build-up of disperse dyes during high-temperature and high-pressure dyeing or thermosol dyeing, clarifying the relevant testing principles and requirements. Build-up refers to the ability of a dye to increase color depth as its concentration increases. The test involves gradient concentration dyeing using equipment such as dyeing machines, electronic balances, and colorimeters. By comparing the dyeing depth at different concentrations, the coloring efficiency of the dye is evaluated, providing technical support for controlling dye dosage in dyeing processes.
