Effect of Mordants on Percentage Absorption of Rubia Cardifolia Dye

Abstract

This study examines the impact of various mordants on the absorption of Indian Madder Root dye by cotton fabric. The Indian Madder Root dye, derived from the roots of the Indian madder plant, is a natural, eco-friendly alternative to synthetic dyes. The mordants used in this investigation include ferrous sulfate, copper sulfate, zinc sulfate, magnesium sulfate, aluminum potassium sulfate, and potassium dichromate. The absorption of the dye was measured using a colorimeter at a wavelength of 680 nm. The results show that the transition metal mordants, such as copper sulfate and ferrous sulfate, exhibit the highest percentage absorption, while magnesium sulfate shows the least absorption. The study highlights the significance of mordants in enhancing the binding of dyes to fabric, resulting in improved colorfastness and retention of color. The findings of this research have implications for the textile industry, particularly in the development of sustainable and environmentally friendly dyeing processes.
