Dyeing of Cellulosic Materials (Cotton and Jute) with Natural Dye Extracted from Onion Skin Using Different Mordants

Abstract

Natural dyes derived from onion skins have gained attention for their eco-friendly properties and potential applications in textile dyeing. This study explores the dyeing of cellulosic materials, specifically cotton and jute, using a natural dye extracted from onion skins. The researchinvestigates the effects of different mordants, including Lemon juice and Tanic acid, on dye uptake, colorfastness, and overall dyeing properties. Experimental results indicate significant variations in color intensity and shade, influenced by the type and concentration of mordant used. UV-Vis spectroscopy and colorimetric analysis were employed to quantify dye absorption and assess color changes over time. The findings contribute to understanding the feasibility and sustainability of onion skin dyeing in textile applications, highlighting its potential as an alternative to synthetic dyes in eco- conscious practices.
