Abstract: Dyeing of polyester with disperse dyes, red 60 and blue 56 was done using microwaves irradiation technique. Different parameters such as dyeing time, dye concentration, power of microwave used and Liquor ratio were studied. Compared the results obtained upon using conventional technique and microwave technique was done. From the results obtained, the microwave technique save about 40 min. in the dyeing time, addition of carrier and dispersing agent, this means that save in time, energy and money. The overall fastness properties to rubbing, washing, light and perspiration for the dyed samples their values ranging from very good to excellent.
