Optimization of the natural dyes extraction (Madder and Wallonia oak) and Cotton Dyeing Using Microwave Irradiation

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 detector (RP-HPLC PAD). CIEL*a*b* spectrophotometer measured colour characteristics of all fabrics. Scanning electron microscopy energy dispersion spectroscopy (SEM-EDX) image colouristic colourfastness properties investigated. According test results, it has been determined that 5 minutes using is very eligible. During processes, timesavings achieved eco-friendly MW minimized damage.
