RESUMO

The textile industry has a high degree of importance in the Brazilian context, the constant fashion change takes to the research for innovation and originality, being created differentiated fabrics with innovative physical properties, finish and textures. Nowadays exist countless textile fibers (natural, animals and synthetic), besides an infinite range of combinations among them; and, and in consideration factors as benefit and cost, speed in the production, etc. it will be studied the polyester fiber (PES), because, besides its versatility it is the textile fiber that more used in the world. One of the most important requirements is the color of the use domestic fabrics and its fastness properties (smaller or larger capacity of color resistance to the use), and this depends on three main factors: the type of chosen dye in function of the fiber that composes the fabric and of the use that will be lead to the same, the employment of the appropriate dyeing process and wash process. The dyeing consists of fixing the dye on the fiber. Therefore, the dyeing depends on the fiber quality and of the dye chemical composition. For polyester fibers the most appropriate dyes are the disperse dyes, that provide a larger performance, fixation and color resistance, besides good fiber fastness properties. In this context, the present work seeks the study the light fastness properties and the wash fastness properties of the polyester fibers dyeing with disperse dye, according to the consumers demands and, following, therefore the ISO Proceeding. The obtained results allowed to conclude that the polyester fibers have good domestic and commercial wash fastness properties with common commercial soap, because, it hardly happens bleaching and color transfer when it used in indicated concentrations. It was also concluded that the polyester has good light fastness, in other words, it has good bleaching resistance when exposed to the light for even 180 hours
