Dyestuffs - Determination of diffusibility

GB/T 27597-2011 "Determination of Dye Diffusion Properties" is applicable to the determination of diffusion properties of disperse dyes and vat dyes, clarifying the test principles and operational requirements. The principle involves observing the diffusion ring formed by the dye suspension on filter paper and comparing it with a standard rating card to evaluate the diffusion performance. The test requires an analytical balance with a sensitivity of not greater than 0.001g, a magnetic stirrer, a graduated pipette, and a watch glass. Strict control of the suspension temperature and dropping conditions is necessary, providing a unified testing method for evaluating diffusion effects in dye applications.
