Abstract
Dyeing of nylon66 (polyamide) fabrics with disperse dyes; blue 56 and red 60 was carried out using microwave irradiation technique. Different parameters mainly, dyeing time, dye concentration, power of microwave, and Liquor ratios were studied. The results obtained as a result of the two dyeing technique were compared. The results revealed that, the microwave technique save about 40 min. in the dyeing time; in addition the microwave technique used no carrier and dispersing agent, reduced time, energy and cost effective as well. The overall fastness properties to rubbing, washing, light and perspiration for the dyed samples were measured and their values ranged from very good to excellent. The Microwave Irradiation Technique saved time, energy and money.
