Extraction of Natural Dyes from Agricultural Waste for Textile Applications

Synthetic dyes used in the textile industry cause serious environmental pollution and health problems. Due to these issues, there is growing usage natural dyes as eco-friendly alternatives. Agricultural waste such as fruit and vegetable peels is produced in large amounts and is usually thrown away. This study explores the extraction of natural dyes from agricultural waste and their use in textile applications. Common waste materials like onion peels, avocado peels, cabbage leaves, and custard apple peels were selected because they contain natural pigments and are easily available. The dyes were extracted using simple methods such as green extraction method and boiling the plant waste in water which makes the process safe, low-cost and environmentally friendly. The extracted dyes were then applied to cotton fabric using basic dyeing techniques. Mordants were used to improve dye absorption and help the colour bind better to the fabric. The dyed fabrics were examined for colour appearance, shade variation, and overall quality. The results showed that agricultural waste can produce a variety of natural colours ranging from yellow and brown to green and pink shades. The colours obtained were visually appealing and showed acceptable durability for textile use. Using agricultural waste as a dye source helps reduce waste, lowers environmental pollution, and decreases dependence on harmful synthetic dyes. This study concludes that natural dyes extracted from agricultural waste have good potential for sustainable textile applications. The process supports eco-friendly practices and promotes the reuse of waste materials. Such natural dyeing methods can contribute to greener textile production and encourage the development of sustainable and environmentally responsible industries .
