Microwave assisted henna organic dyeing of polyester fabric: a green, economical and energy proficient substitute

The proposed work, aims to provide a green and cutting-edge technique for the mordanting and dyeing of polyester fabric with natural henna dye using the advanced technology of micro waves. For providing a complete green and ecofriendly dyeing process, lemon was used as a natural bio mordant with micro waves and results were compared with conventional mordanting method followed by the natural henna dyeing of polyester fabric with microwave. Color properties were analyzed in detail. Scanning electron microscope (SEM), WIDE ANGLE X-RAY DIFFRACTION (WAXD) and Fourier transform infrared spectrometer (ATR-FTIR) studies provide the details of surface and structural changes induced by microwave lemon mordanting and henna dyeing of polyester. Microwave technique clearly reduced the mordanting and dyeing time upto 60-65% with improved fixation and color characteristics. [GRAPHICS] .

Automated summary

The study aims to provide a green and cutting-edge technique for dyeing polyester fabric with natural henna dye using microwave technology. By incorporating lemon as a natural bio mordant, the microwave technique was able to significantly reduce dyeing time and improve fixation and color characteristics compared to conventional methods.
