Natural dyes have gained significant attention in textile dyeing due to their eco-friendly properties and aesthetic appeal. Onion skins, a readily available agricultural waste product, possess natural dyeing capabilities that can impart various shades of yellow and orange to textiles. However, achieving consistent and vibrant colors requires the use of mordants, which enhance dye absorption and colorfastness. In this study, the focus is on optimizing dyeing variables when dyeing cotton with onion skin dye, employing natural mordents such as alum, lemon, harda (myrobalan), tamarind leaves, and Aloe vera. Mordents play a crucial role in dye fixation by forming complexes with the dye molecules, thereby improving color intensity and wash fastness of the dyed fabric. The selection of natural mordents is based on their traditional use and effectiveness in enhancing dye uptake and color retention. Each mordant offers unique properties that can influence the final color and durability of the dyed cotton fabric. By systematically varying dyeing parameters such as mordant concentration, dyeing time, and temperature, this study aims to optimize the dyeing process to achieve desirable color outcomes while minimizing environmental impact. Understanding and optimizing these variables not only contribute to the sustainable utilization of natural resources but also expand the repertoire of eco-friendly dyeing techniques in the textile industry. The results obtained from this research provide valuable insights into the practical application of onion skin dye with natural mordants, paving the way for enhanced utilization of natural dyes in textile production.
