Abstract(s)In recent years, textile industry in developed countries is challenging an increasing global competition due to the changed world market conditions. Moreover, the increasing environmental and health concerns owing to the large quantities of water and hazardous chemicals used in the conventional textile finishing techniques lead to the development of new technologies. In recent decades, plasma technology has assumed a great importance among all available surface modification processes. It is a dry, environmental- and worker-friendly method to achieve surface alteration without modifying the bulk properties of the materials [1-2]. In particular, non-thermal plasmas are especially suited because most textile materials are heat sensitive polymers [3]. In this work were studied two topics: (1) the physico-chemical improvements occasioned by DBD plasma discharge in dyeing process of polyamide 66 fibers and (2) the possibility to reuse the effluent obtained for a new dyeing process.
