Abstract

In this research, dissolution of a disperse dye in the presence of Tween 20 and Tween 80 and the effect of various parameters such as time, temperature and concentration of dispersing agents were investigated. In addition, dissolution kinetics of disperse dye in the presence of selected dispersing agents in various temperatures were studied. Results show that dissolution kinetics of the disperse dye follows an exponential equation. The rate of dissolution of disperse dye in the presence of Tween 80 is greater than Tween 20. The performance of Tween 80 and Tween 20 in dyeing of polyester fibers with disperse dye were studied and compared with the performance dispertane MF as a commercial dispersing agent. Results show that the performance of Tween 80 is almost equal to Dispertane MF.
