Abstract/Executive Summary
The textile industry faces challenges in its dyeing processes due to the toxicity of synthetic dyes, significantly endangering the environment and human health. This study explores the use of natural dyes as a sustainable substitute for synthetic dyes in the textile industry, aiming to mitigate these environmental and health risks. The peels of Carabao mango (Mangifera indica), which are abundant in the Philippines, were utilized as a sustainable and eco-friendly alternative source of natural dyes. An aqueous extraction technique was employed to obtain natural dyes from mango peels. A synthetic dye, the Master fast dye, was used as a reference dye to be compared with the cotton fabric samples dyed using the mango peel dye at different mordant combinations. The performance of these dye and mordant formulations was tested for color fastness to water, light, and rubbing on cotton fabrics and evaluated using UV-Vis spectroscopy and AATCC 5-step grayscale. The results indicate that while the synthetic dye performs better in water submersion tests, the dyes obtained from mango peels show superior performance in color fastness to rubbing and sunlight exposure. This study suggests that mango peel dyes have the potential to be an eco-friendly and effective alternative to synthetic dyes in cotton fabric dyeing, highlighting the importance of further exploring natural dye options to reduce the environmental and health impacts associated with synthetic dyes in the textile industry.
