A anew technique represented in this study for evaluating the performance of dyeing cotton fabrics using infrared (IR) heating technique compared to the conventional exhaust dyeing method. The effect of this new technique has been studied on the color strength (K/S), color fastness properties, tensile strength and elongation of the dyed cotton fabrics made of two Egyptian varieties Giza 90 and Giza 95 using Procion H-EXL blue reactive dye with concentrations 2%, 4% and 6% . The color strength values of the infrared heating technique in dyeing were better than those of the exhaust dyeing obtained using the same dye concentration 4% and the same recipes. Also the results for dyeing using infrared heating technique had no bad effect on the color fastness or on the dyed cotton fabric mechanical properties.
