Abstract:

Dyeing is a crucial and complex process in the clothing industry. Textile processing industries are major environmental polluters, of synthetic dyes. So to avoid this pollution, extraction of dyes was done from food products, which is the by-product of household. Dyes derived from natural sources have emerged as an important alternative to synthetic dyes. The present scenario with global concern is the encouragement of developing natural color pigments, using eco-friendly and biodegradable materials. Therefore, in this study, household waste materials like tea waste, dried Hibiscus flower, pomegranate peels, used coffee grounds, etc., were used to extract the dye with the use of a mordant such as alum for better color absorption. The color developed was used on cambric fabric and tested for washing properties (colorfastness).
