Physical Properties of Natural Dyes Based on Lawsonia Inermis, Azadiractha Indica and Curcuma Longa Coated With Superhydrophobic Coating for Textile Applications

Natural dyes based on Lawsonia Inermis, Azadiractha Indica and Curcuma Longa were used in this study to produce eco-friendly and non-toxic fabric to the people. The extraction process of natural dyes is aqueous technique and hot bath dyeing. The aim is to find the optimum concentration of natural dyes and superhydrophobic coating on cotton fabric for green technology dyeing. The data obtained is subjected to quantitative analysis. It is found that coated fabrics have higher physical strength than uncoated fabrics. The coated scale for crocking test, weather resistance of fabric and washing test are 5 (excellent) compared to the uncoated dyed cotton fabric. The optimum concentration obtained from Lawsonia Inermis, Azadiractha Indica and Curcuma Longa is F (1.50 g/ml). The results can help to reduce the usage of synthetic dye in textile application.
