As the stringent norms are fixed on the characteristics of discharged effluent, there is always a demand for chemicals/auxiliaries which can reduce the pollution load of effluent.
Normally soda ash is the most commonly used alkali in reactive dyeing. However, dye fixation on cellulosic fibers is generally low. As much as 50% of the total cost of a reactive dyeing process is attributed to the washing-off stages to remove unfixed or hydrolyzed dyes and treatment of the resulting effluent. Furthermore, the higher concentrations of alkali required in cellulosic dyeing may pose additional effluent problems. The limitation of a conventional treatment scheme in removing the inorganic TDS has restricted the recovery and reuse of water from the resultant combined stream in other processing. Also, the repeated recirculation of conventionally treated water causes a further increase in TDS during the process recirculation and treatment stage. Recirculated water also affects performance of dyeing.
Under this circumstances, Greensoda 1000 Powder works out superior over soda ash in dyeing of cotton fabric with reactive dyes. It is required in 1/4th dosage compared to conventional soda ash which results in substantial reduction in TDS of dye bath as compared to that of Soda Ash. This results in much lower TDS in effluent causing much less trouble in effluent treatment.
Greensoda 1000 Powder is a concentrated alkali buffer with superior performance than soda ash, especially in reactive dyeing.
