Abstract

Some new disperse dyes has been prepared and used in dyeing polyester fabrics at a temperature of 130 °C and a study of the optimum conditions for the use of the dispersing agent. The relationship between the dye concentration used in dyeing polyester fabrics with dispersed dyes and the color strength K/S were studied using three different concentrations of dye weight. Finally, polyester fabrics dyed with disperse dyes have shown that they possess very good fastness against washing, perspiration and rubbing and acceptable fastness properties of light.
