INTRODUCTION: Natural dyes offer an eco-friendly alternative to synthetic colorants in textile processing. This study explores the sustainable dyeing of cotton, silk, and leather using pigment-rich extracts from MATERIALS AND METHODS: Using an array of extraction solvents [water, methanol, ethanol, ethanol: methanol (1:1)] and extraction techniques [direct heat (DH), ultrasonic water bath (USB), ultrasonic probe, (USP)], RESULTS AND DISCUSSION: Using methanol as the solvent and 5 g of seed at 60°C for 60 min, the highest color yield was observed in USB. Using the ultrasonic water bath dyeing method at 60°C for 40 min without using any moderant, cotton, silk fabric, and leather were effectively colored in a yellow-orange color. The L*, a*, and b* values of the dyed material treated using the USB approach were 80.95, 4.52, 75.35 for cotton, 88.65, -1.35, 62.85 for silk, and 79.55, 015.35, 66.45 for leather, respectively. Compared to the other bacterial reduction, 85.25% of the colored materials showed substantial antibacterial action against
