"GB/T 5540-2017 Disperse dyes, determination of dispersion performance double-decked filter paper filtrate method" stipulates the method of using double-decked filter paper filtrate method to determine the dispersion performance of disperse dyes. The principle, instrument reagents, operation steps and result rating are described in detail. By standardizing the filtrate process and observing the residue of filter paper, it provides a unified standard for accurately evaluating the dispersion performance of disperse dyes, which is helpful to control the dyestuff mass and guide the production and application of dyestuff.
