Popis: Recently, natural dyes are used because these are environment-friendly, less lethal, and do not have any detrimental effect on health. For the present study, the cotton fabric and the mixed powder (pomegranate rind and turmeric rhizome) have been irradiated for (1–5) min. It has been found that 3 min is the effective exposure time for improvement in dyeing behavior of cellulosic fabric. Good color strength was observed by dyeing fabric irradiated at 65°C for 40 min in dyeing bath having pH 6. For improvements in color fastness, the optimum concentration of pre-mordant (4% copper) and post-mordant (8% chrome) was employed. It is observed that microwaves increased the color strength as well as color fastness properties of irradiated cotton using aqueous solubilized mixed extract of irradiated pomegranate rind and turmeric rhizome powder.
