Application Summary AI generated
GB/T 5541-2017 specifies a test method for evaluating the high-temperature dispersion stability of disperse dyes by filtering a dye dispersion through double filter papers. It is applied in the textile chemical industry, particularly for quality control of disperse dyes used in high-temperature dyeing processes of polyester and other synthetic fibers. The standard ensures that dyes maintain uniform dispersion without agglomeration or precipitation under thermal conditions, preventing defects like spots or uneven coloration in dyed fabrics.
