| Abstract: | In this paper the change of average particle sizes of disperse dyes before and after subjecting to high temperature treatment, which usually indicates their high temperature dispersion stability, was measured by Laser Size Analyzer KS13320. The experiments demonstrated that the concentration of anionic dispersing agents in dye bath must be sufficient enough to maintain high temperature dispersion stability of disperse dyes. The anionic/ anionic or anionie/nonionic composite surfactants were more efficient than a single dispersing agent MF to enhance high temperature dispersion stability, but such formulation is very selective to disperse dye molecular structure. |
