Extraction of Eco-Friendly Natural Dye from Variety of Vegetables

Abstract

A large number of experiments have been performed of natural dyes from plants and vegetable wastes. Natural dyes helps in the reduction of pollution level in textile dyeing, in realization of eco- friendly agriculture productions, and pollution. The main idea of extracting dyes from natural sources is to avoid the environmental pollution. Present days with global concern over the use of eco-friendly and bio degradable materials, considerable research work is being undertaken around the world on the application of natural dyes in textile industry. The present study deals with the extraction of natural dye from this species, and their application on textiles. Pre mordant technique methods for extraction of dye from collected vegetables were evaluated to determine. The cotton types of fabrics were used in the experiment to observe the strength of dye. This method following steps: vegetables are naturally dried, and are added into deionized water for soaking then baking soda is added for regulating the pH value to 6-8, the temperature is increased to 70-100 and is maintained for 60-90 min, and the obtained product is cooled and filtered, and residue is removed. The vegetable dye is obtained. The various extract were analysed phytochemical compounds. The extracts were then treated with cotton fabric using the various chemical mordants. Based on analysis, the best mordant and technique for using mordant were determined for dying fabric.
