The influence of ultrasound on changes in dye particle size and the specific breakage rate of disperse dyes with different crystalline properties are investigated. The results show that ultrasound breaks larger dye particles suspended in water in their insoluble form into finer dye particles and reduces the mean particle size of disperse dyes. The specific breakage rate for dye particles irradiated by ultrasound depends on their crystalline properties, and the breakage rate of a well crystallized dye is higher than that of a poorly crystallized dye.
