Global consciousness towards the organic value of eco-friendly products has attracted the interest ofpeople towards the use of naturally dyed textiles and organic mordants. The present study has beenfocused not only on exploring the bio-colourant activity of Phyllanthus emblica (Amala) but also onthe application of natural mordant for textile dyeing and analysis of its medicinal properties. It hasbeen discovered from the investigation that biomordants like extract of Aloe vera’s as well as extractof mango’s bark extract were able to evince their characteristic colour ameliorate behaviour close tosynthetic ones. Besides, the disparity in absorbance band in ultraviolet spectroscopy, distinction infunctional groups and differences in surface morphology of two extracted dyes were observed thatprovided information on colour variation in the cotton fabrics. An eagle gray shade and brown-huedon the cotton fabric were noticed from water and ethanol extracted dyes, respectively. Further, it isconfirmed that the natural dyes contain bioactive phytochemicals like tannins, phenols and flavonoidsthat provide a significant antibacterial activity which will help it to be beneficially utilized in protectivemedical clothing.
