GB/T 5541-1985 specifies the method for determining the high temperature dispersion stability of disperse dyes. The standard details the instruments, reagents and specific operation procedures required for the experiment, and determines the high temperature dispersion Stability by observing and evaluating the dispersion state of disperse dyes under specific conditions. With the help of this standard, it can effectively detect the performance of disperse dyes in high temperature environments, providing an important basis for dyestuff manufacturers to control the mass of products, Spinning & weaving The printing and dyeing industry rationally selects dyestuff, and plays a normative and guiding role in related fields.
