Abstract: In the present study, experiments were carried out to use an extract isolated from floral petals of Ixora coccinea (Linn. ) with aqueous and methanol as a natural dye. The dye potential of the extract was evaluated by dyeing on cotton fabrics under the normal dyeing conditions and tested for their colour fastness to washing properties. The pigments were isolated from fresh flowers of Ixora coccinea (Linn. ) and studied in order to understand the process of dying during cotton cloth coloration using different mordants such as Alum, Copper sulphate, ferrous sulphate and Stannous chloride. The various shades were obtained by Ixora coccinea (Linn. ) flower on cotton fabrics. Aqueous extract without mordant (Control) exhibits Windsor cream 6860 shade that is matched with Walnut cream 8778, Riverbed Sand 8462, Dark ash 8776 and Pampered Pink 8696 shades obtained in Alum (5 %), Copper sulphate (2 %), Ferrous sulphate (2 %) and Stannous chloride (2 %) respectively. Shades generated in mordants were all unique and different than control. The results revealed that the Methanolic extract of Ixora coccinea (Linn. ) flowerextracted more pigments and exhibits dark shades on cotton fabric as compared to aqueous. Methanol Control exhibits bright Rose petal 0208 shade that is matched with shades obtained in respective mordants i. e. Sparrow feather 8659, Quarry stone 8658, Digital grey 8312 and Dash of purple respectively. The shade obtained is matched with Asian-paint color shades card which makes it easier for the user to communicate about the shade without actually sending sample. The changes in shades of some of the colors have been noticed after washing with soap. The Spectroscopic analysis of dye color have also been made for identification of certain bonding /functional groups present in the dye extract, the technique can used to identify the interaction of the dye with mordents. Secondly, mordanting with the different metal salts exhibited variation in color hue because of their ability to form coordination complexes with the dye molecules, which resulted in different shades to cotton fabrics. These findings revealed that the extract of floral petals of Ixora coccinea (Linn). can be used for cotton fabric coloration.
