Optimization of Raw Material usage in Manufacturing of Dye–A Cleaner Production Technique

There is no denying the fact that dyestuff industry is the major growth driver all around especially in the textile and chemical industries in the country. India is one of the major supplier of the dyes and dye intermediates from the Asian region and can meet the requirements of the world at large provided adequate incentives and facilities are made available. The dye industry achieved growth rate of 15% during last year. India’s share in the world market is estimated at 5-6%. The Share of Gujarat in all Indian export is about 60%. The major markets for Indian dyestuff are the European country, USA, South Korea, Hong Kong. Manufacturer are suffering due to competition in market by the other country like china, so to with stand with them it is necessary to optimize the manufacturing process either Production cost ,Raw material cost or Energy cost which is the ultimate way to stand in competitive market. To achieve the above mentioned thing Cleaner Production is applied. Cleaner Production means economic savings from reduced consumption of raw materials and energy and lower treatment costs as well as other benefits such as a better company image and better working conditions. Fiber reactive dyes are commonly employed for textile dying; the use of these dyes can introduce high costs and environmental concerns. For example, their fixation levels can be as low as 50% and high salt levels are typically needed to achieve desired shades. Thus, a mechanism for increasing fixation and exhaustion efficiencies in an economical way would enhance the value of these dyes to the textile industry. With these points in mind, ‘Optimization of Raw material usage in Manufacturing of Reactive Dye’, one of the cleaner production technique that holds promise for achieving desirable exhaustion and fixation efficiencies. Specifically, the reactivity and affinity of Reactive Blue (Blue RGB) dye. Modified dye is also cheaper than conventional dye. In laboratory study it was determined that modified dye gave the best results in affinity, shade depth assessments and cost.
