Abstract

CARRIER coloring is a technique for dyeing polyester materials that is utilized when vital. Use of carriers in coloring empowers the coloring of polyester materials at atmospheric pressure. A series of new disperse dyes has been prepared and used in dyeing polyester fabrics at a temperature of 100 °C and a study of the optimum conditions for the use of both the carrier and 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 acceptable fastness properties of light and are very good fastness against washing, perspiration and rubbing.
