Summary: The overall theme of this thesis is part of the pollution abatement, through direct reuse of the baths of dye colored polyester dispersed. Research has desarrollarado taking into account the impact of recycling on the quality of the product, meaning that the color differences introducing the substrate with a dye bath reuse in respect of which was stained with the initial bath. In research conducted in the area of reusing dye baths in various textile fibers, the greatest potential for reuse of their bathrooms, is the polyester, which is due to the increased consumption of synthetic fiber in the world market. A special case within the polyester fiber is the micro, because they possess the highest specific area requiring much greater amount of dye that a conventional fiber. Polyester fibers stained with only scattered colors, but which have a good exhaustion at the end of the dyeing process, and was in the bathroom enough dye to be despised and could not be used without restriction for the next cycle dye. In research conducted in recent years, the technology of reuse, although it apparently is feasible for industrial application, it leaves some doubt that through this work is intended to address and give a clearer explanation of what happens with colors when the dye bath is reused many times, especially when these are mixed. Most of the work done on the direct reuses of the dye baths, have focused on the analysis of the dyes in monocromías they have studied reuse of mixtures of colors is not the recipe has remained constant dye and has been limited to begin the process of dye with low concentrations of colors and in the following process, conducted with the reuse of their bathroom, was used for another recipe dye with a much higher concentration of colors to finish with dark tones. According to all the above, the fundamental objective of this dissertation is to study the impact of direct reuse of the baths of dye colored polyester microfibre scattered on the reproducibility of the final color in monocromías, binary and ternary mixtures of three primary colors. Therefore it has been raised another methodology for the study of the potential for direct reuse of the baths of dye for making the influence on the final color of the fabric to maintain constant concentration process tintóreo. Moreover, it is essential to study color through full color differences between tissues ÃL *, Ãa * Ãb * Ã
