Abstract:

The present research is based on dyeing of wool/cotton blended yarn using poly-functional reactive dye with Tri sodium citrate as an exhausting agent and EDTA (tetra sodium salt) for fixation in single bath and two-step process. The first step bath is slightly alkaline and second step is acidic medium for dyeing. Both are bio-degradable organic salts having more number of anionic sites than conventional inorganic chemicals i.e. sodium sulfate and sodium carbonate, so the reactivity with fiber and dye is much greater than ordinary salt. A major environmental problem of textile effluent is from the dyeing waste water, colorants, heavy metals, and high concentrations of inorganic salts are all water pollutants. The major effort is on the removal of toxic materials from the effluent and tries to decrease the concentration of these chemicals in the effluent discharged. Since, both the chemical are biodegradable hence it may help in reduction of pollutant in effluent. As both are the organic salt and having a bio degradable nature, it reduces the load of effluent treatment plant in industry in terms of cost and reduces the BOD and COD level and also reduces the criticalities of dyeing of wool-cotton blend.
