Abstract
Natural dyes yield a remarkable range of items with complex colouration that go well together. Skin that constitutes the outermost part of onion contains certain phytochemicals, such as; cardiac glycosides, tannins, flavonoids (quercetin, etc.), anthocyanidins (pelargonidin, etc.), natural dyestuffs, and reducing sugars in aqueous medium. Among the various phytochemicals, tannins, anthraquinones, and flavonoids are crucial for giving cotton fabric its shade and vibrancy. Wool has been dyed in the past and present using onion peel. It has historically been utilised in rugs and carpets in Anatolia, Turkey. It can be applied both with and without bio-mordants to silk fabric. Tea leaves, tamarind, aloe vera, and ash from acacia bark are utilised as bio-mordants. Furthermore, colour measurement values, such as Tristimulus characteristics, Lab values, and munsell notations, are applied to dyed materials.
