Two DIFFERENT weights of 100% polyester fabrics were printed with meypro gum thickening agent containing sodium hydroxide with different concentrations. Different steaming time and temperature were also applied to determine the optimum conditions for this alkali printing of polyester fabrics .polyester fabrics including first prints were overprinted with a second print paste containing disperse dye. Some working properties of the printed fabrics like air permeability and water repellency were improved. Colour strength of the printed areas was also increased. Using of ammonium compound surfactants increases weight loss and accelerates the treatment.
