GB/T 5540-2007
AbolishedDisperse dyes - Determination of dispersbility - Filter test of double filter papers
分散染料 分散性能的测定 双层滤纸过滤法
Application Summary AI generated
This standard specifies a method for evaluating the dispersibility of disperse dyes by passing a dye dispersion through two layers of filter paper and assessing the residue. It is primarily applied in the textile dyeing industry to ensure that disperse dyes used for polyester and other synthetic fibers disperse uniformly in water, preventing specking or uneven coloration during high-temperature dyeing processes. The test is critical for quality control in dye manufacturing and for dyehouse laboratories verifying batch consistency.
