Abstract	The market globalization stimulated the companies, in general, to become worldwide competitors and to produce ecologically correct products, manufactured with processes that protect the environment, generating a minimum amount or prevent any types of wastes (solid, liquid and gas). In the finishing process, that comprehend the of purge, mercerizin, desizing, bleaching and dyeing operations, the biggest volume of liquid effluents are generated, with high contaminant load depending on the type of operational process, raw material used and of the final product. The reduction of the effluent volume, through recirculation and chemical products and by-products recovery, without interfering finished product quality, constitutes the biggest challenge faced for the textile industry. The main goal of this work is the characterization of the effluents of the preparation and dyeing steps, aiming to increase the efficiency in the use of chemicals, water and energy, through the minimization or effluents recycling generated in the productive process of the Textile Industry. The determined parameters were: color, turbidity, temperature, pH, partial and total alkalinity, condutivity, iron, suspended solids, fixed solids, total dissolved solids, and organic matter determined by the chemical oxygen demand, of a big textile industry located in Santa Catarina. It was established a strategy for reutilization effluents from the stocknitte from batches in the following colors white, black, of clear intensity, of average intensity and of dark intensity. For the efluents that couldn't have direct reutilization, technological alternatives are proposed making possible their reutilization.
