Ultrasonication-aided dye extraction from waste onion peel and eco-friendly dyeing on organic cotton fabric with enhanced efficacy in color fixation

Ultrasonic-assisted sustainable extraction and dyeing of organic cotton fabric using natural dyes from Dillenia indica leaf

“…Researchers in the dying industry are continuously exploring new plant sources to discover natural dyes and pigments that can address the environmental concerns associated with most synthetic and natural dyes [ 5 ]. In this context, we conducted experiments to extract natural colors from waste onion peel [ 6 ], black rice [ 7 ], gardenia yellow [ 8 ], tulsi leaves [ 9 ], Butea monosperma plants [ 10 ], Alkanna tinctoria roots [ 11 ], Coral Jasmine flower [ 12 ] and neem leaves [ 13 ]. However, a significant drawback of natural dyes is their limited affinity for textile materials.…”
