Characterization of Color and Application of Natural Dyes from Hagonoy (Chromolaena odorata) Leaves on Cotton and Wool Fabrics

This study examines the characterization of color and application of natural dyes from Hagonoy (Chromolaena odorata) leaves on cotton and wool fabrics. A descriptive-experimental research design was used, employing the maceration method for dye extraction. The fabrics underwent unmordanted, premordanted, metamordanted, and postmordanted processes using potassium aluminum sulfate and ferrous sulfate as mordants. The dyed fabrics were tested for stability under washing, sunlight, and perspiration (acidic and basic) conditions. A colorimeter measured the Lab values, and color differences (ΔE) were analyzed for comparison. Cotton fabrics (ΔE=1.75) showed better dye uptake and stability than wool (ΔE=10.84). Among mordants, ferrous sulfate (ΔE=13.78) produced darker but less stable colors, whereas potassium aluminum sulfate (ΔE= 2.57) yielded brighter and more stable results, especially at lower ratios. Metamordanting on cotton emerged as the most effective process for enhancing dye performance. The study underscores the potential of Chromolaena odorata leaves as a sustainable and eco-friendly dye source for the textile industry, offering an alternative to synthetic dyes that aligns with global environmental objectives.
