Exploration of Natural Dyes and Mordanting on Cotton Fabric with Monochromatic Color Combinations

Abstract

This study explores the use of natural dyes as a sustainable alternative to synthetic dyes in the textile industry, with a focus on creating monochromatic color combinations on cotton fabric. Using a qualitative descriptive experimental approach, this study tested the effectiveness of pigments derived from indigo, secang wood, mangosteen peel, and turmeric through variations in mordanting techniques (pre-mordanting, meta-mordanting, and post-mordanting). The mordants used include alum and tunjung to observe the resulting color shifts and visual intensity. The results indicate that the post-mordanting technique with tunjung mordant produces deeper and more intense color saturation, while alum preserves the original color brightness. A systematic monochromatic effect was successfully achieved through modifications in solution concentration and dyeing duration, without the addition of synthetic dyes. Additionally, it was found that drying in the shade provides better color stability compared to direct sunlight exposure. This study concludes that the optimization of mordanting variables and consistent technical procedures can produce color gradations that are aesthetically pleasing, harmonious, and environmentally friendly. These findings are expected to serve as a reference for the development of textile designs that prioritize the principles of the circular economy and sustainability
