Effect of ultrasound on disperse dye particle size

The potential of ultrasound as a means of enhancing dyeing efficiency is ev aluated. Changes in the particle sizes of a disperse dye dispersion with ul trasound irradiation are studied using the turbidity concept, and the effec t of particle size on the exhaustion rate is also investigated. Ultrasound irradiation of a dye dispersion reduces the particle sizes of disperse dyes , and the exhaustion rate of the dyes on fibers is enhanced by this reduced particle size by the ultrasound pretreatment before dyeing experiments.
