AbolishedDisrerse dyes - Determination of stability of dispersion at high temperature - Filter test of double filter papers
分散染料 高温分散稳定性的测定 双层滤纸过滤法
Application Summary AI generated
This standard specifies a test method for evaluating the high-temperature dispersion stability of disperse dyes by filtering a heated dye dispersion through two layers of filter paper. It is applied in the textile dyeing industry to assess whether a disperse dye will remain uniformly dispersed without agglomerating or precipitating during high-temperature dyeing processes, such as polyester dyeing. The method ensures dye performance and prevents defects like specking or uneven coloration in the final fabric.
