A conventional microwave oven, a &pass rectangular microwave applicator coupled to a magnetron operating at 2450 MHz and a hot air dryer of standard Benz type were used to fiz disperse dyes on polyester component of apolyester/cotton blend fabric. The use of apolar chemical additive (urea) was found to be required for disperse dye transfer from the cotton mmponent of the blend and its f~tion. A direct measurement of the temperature was not possible. The use of melting crystals and thermopapers was also not satisfactory due to absorption of microwaves by the glue used. Several attempts were, therefore, made to assess the temperature reached by the fabric in the microwave unit
