Polyester fabric was hydrolysed using aqueous sodium hydroxide under microwave irradiation. Increasing levels of weight loss and thickness reduction were observed with increasing microwave intensity and increasing concentrations of sodium hydroxide. Comparison of the results obtained from the microwave irradiation method and the conventional heating method showed that the rate of hydrolysis was greater using microwave irradiation. The treated fabric was then dyed using microwave irradiation to heat the dyebath. Increased levels of dye uptake were observed with increasing weight loss of the hydrolysed polyester fabric.
