ECO-FRIENDLY DYEING OF COTTON USING NATURAL DYE FROM SWEITENIA MAHAGONI (BARK) AND EXAMINATION OF ANTI-MICROBIAL ACTIVITY

Textile Engineering

Around the last sixty years, natural dyes were out of practice and industries were into synthetic dyes, and now natural dyes are again becoming an object of consumer interests. The objective is to evaluate the potential of mahogany wood waste powder as a natural, plant- based antibacterial agent for use in textile applications. The findings suggested that mahogany wood waste powder has potential as a natural, plant-based antibacterial agent for use in textile applications. Most synthetic dyes used in the textile industry are non-biodegradable, carcinogenic, and significantly harm the environment. Natural colouring compounds were isolated using an aqueous extraction method, and organic cotton fabric was coloured with the extracts after being mordanted with several mordant types including ferrous sulphate, potassium aluminium sulphate, and stannous chloride. .Dyeing is a crucial textile technology procedure and all over the world the colouring of textile material is done with bleached fabric using natural and synthetic dyes. The wash, light, rubbing, and perspiration fastness qualities of coloured organic cotton fabric were investigated. The organic cotton fabric coloured with wood waste was found to have good to excellent fastness qualities. The scanning electron microscopy images revealed that the dye particles were present on the dyed fabric surfaces. Therefore, utilizing naturally derived dyes from mahogany wood waste to colour organic cotton fabric may be a good substitute for synthetic dyes in the textile sector due to environmental concerns.. The treated OCF is tested against Escherichia coli and Staphylococcus aureus using the agar disc diffusion method. The results showed that the treated fabric exhibited a significant antibacterial effect. The antibacterial activity decreased with repeated washing, but the treated fabric still showed some level of activity even after ten washes. Overall, Mahagoni serves as a sustainable substitute for synthetic antibacterial agents in the textile sector.
