From past few years due to eco-friendly nature of people, the use of natural dyes has increased several folds. Natural dyes can be obtained from the pigments that contained from various parts of plants like leaves, fruit and rind of the plant. The use of natural colorants in textile is attributed to the increased awareness about environmental contamination created by intermediates and harmful chemicals which are used in synthetic dyeing process. The natural colorants are non carcinogenic, easily biodegradable and non toxic for living organism. Considering energy saving and environmental safety, natural dyes have attracted the attention of researchers and industrialists to be used in textiles and other allied industries. Moreover, plants based natural dyes also exhibit antimicrobial, antioxidant, which make these ideal to be used in the textile and other related industries. A lot of techniques are being used to improve dyeing behaviour of natural dyes and modification of fabric either by improving extraction process or by enhancing dye uptake activity of fabric to get good shades and fastness properties. Normally, pitaya peels are discarded as garbage while processing. The flesh and peel is a potential source of colour for food dye and colorant. Dragon fruit peel consists of betacyanin pigment (0.15 %) and pectin (10.8 %) was high in the peel.
