GB/T 2375-2013 "Direct dyes — Determination of shade and strength" applies to the determination of shade and strength of direct dyes on cotton textiles, specifying the corresponding testing methods and requirements. The test involves accurately weighing the sample using an analytical balance with a sensitivity of not more than 0.0001g. The dyeing conditions are controlled using a laboratory dyeing machine, where the sample and the standard sample are simultaneously dyed on pure cotton textiles. The results can be evaluated visually or measured using a colorimeter according to relevant standards, providing support for quality control of direct dye products.
