Cotton Dyeing with Natural Dye Extracted from Pomegranate (Punica granatum) Peel
Journal Title: Universal Journal of Environmental Research and Technology - Year 2011, Vol 1, Issue 2
Abstract
Use of natural dyes has increased several folds in the past few years due to the eco-friendly approach of the people. This paper concerns with the purification of natural dyestuff extracted from an abundantly occurring plant ‘Punica granatum’. The main coloring agent in the pomegranate peel is granatonine which is present in the alkaloid form N-methyl granatonine. Solvent extraction method was used for the extraction of the dye. The pomegranate peel dye was used for dyeing of scoured cotton cloth using two mordants-copper sulphate and ferrous sulphate in the ratios 1:1, 1:3, 3:1. Dyeing along with mordanting techniques which included premordanting, simultaneous mordanting and post mordanting was carried out. Study about fastness tests of dyed clothes was undertaken. Large range of shades was obtained because of varying mordant ratios and combinations. The production cost of the pomegranate peel dye was estimated.
