Abstract

Environmental awareness is the most often talked subject in today's industrial and social scene all over the world. In India, right now the quantum of problem associated with the effluent by industrial waste is small but with rapid industrialization, increases rapidly to a significant level. Chemical processing of textile material is one of the leading consumers of water (50 to 300 liters of water per kg of textile material) and the second biggest effluent generating industry. Among the various wet processing steps, pretreatment process, utilize the highest amount of water. Many approaches, namely, development of machines/techniques to reduce liquor consumption, application of green chemicals, biotechnology applications, quality control and inventory management, and others have been made to minimize water/effluent minimization. In the present research, the two important steps in pretreatment process, namely mercerization of cotton and scouring of synthetic fibers have been centralized through water consumption to minimize effluent loads. Both these processes have been performed in the present work through the application of solvents (no water used). After the said pretreatment processes more than 90% of solvent can be recovered and recycled for next processes. The new innovative processes were compared with the conventional processes. The results obtained are quite comparable to that of conventional process and encouraging. In future commercialization of these processes will be tried.
