In this work, microwave irradiation was used to extract two dye plants (Quercus ithaburansis Decaisne and Rubia tinctorum L.) natural cotton. Using (MW) energy, the extraction time for these dyeing organic cotton fabric were optimized. The colouring compounds analysed in extractions dyed fabrics by reversed-phase high-performance liquid chromatographic method coupled with a photodiode array det...

Reducing pollution in various industries such as textile is very important. In this paper, two parallel methods were used to reduce of the process and application dye. The first approach was selection plant-based dyes (Madder with botanical name Rubia tinctorum Reseda odorata) a tannin-based mordant (pomegranate peel Punica granatum). second extraction dyeing ultrasound media. efficiency madder...
