ABSTRACT

Natural dyes are extracted from natural resources which will be able to dye almost all types of natural fibers. Extracting dye in such way that it will have better biodegradable activity thus less harm to environment. There is a high time to use such sustainable methods in order to protect the environment from exploitation. The main objective of extracting dyes from plant (natural) sources is to reduce the environmental pollution as well as to reduce hazard to human health. The aim of the present study was to evaluate the efficiency of dyes extracted from leaves of Codiaeum variegatum - Gold dust and Red ice ton in dyeing of fabric. Extraction medium was optimized by extracting dyes from fixed quantity of crushed leaves under pH values 2, 3. The maximum relative colour strength of the extracted dye was found to be at pH 2. The optimum dye extraction conditions i.e. temperature, time and material-to-liquor ratio were found to be 100oC, 60 min, and 1:10 respectively. Dyeing was carried out on fabrics using the extracted dye. The dyed materials were evaluated by measuring the colour yield and fastness properties. It can be concluded that the colour values were found to be influenced by the addition of mordant which are stannous chloride, copper sulphate and ferrous chloride consequently different types of hues were obtained from the same dye extract using different mordants. It can also be said that Codiaeum variegatum leaves have good potentiality for dyeing of fabrics. Apart from their application in textiles, natural dyes are also used in the food colour, medicines, handicraft articles and leather processing.
