The objective of this study was to investigate the behavior in finishing of textile materials made of man-made fiberscontaining ZnO in blends with cotton. It has been studied the possibilities of reducing the concentration of the chemicalagents considered to be aggressive for the functional textile fibers, the temperature and the duration of the processes,as well as the number of technological operations performed, so that the dyeing quality will not suffer and the dyedsamples to be acceptable from the uniformity and fastness point of view. To highlight the influence of the chemicalauxiliaries used in finishing operations, the process temperature, pH and the treatment duration on the phys -ical-chemical and physical-mechanical characteristics of the functional fibers, various methods of preliminary treatmentand dyeing were applied in different experimental variants. In order to assess the preliminary treatments performancefrom whiteness degree and hydrophilicity point of view, the fabrics were tested before and after preliminary treatments.Finished fabrics (preliminary treated and dyed) were tested for the efficiency of the performed treatments in terms ofcolor difference attributes and color fastness. The finished fabrics were also characterized in terms of the main physical-chemical and physical-mechanical characteristics: mass, tensile strength, tearing strength, water vaporpermeability, air permeability. SEM analysis was used to investigate the surface morphology of treated fabrics.Antibacterial activity of treated samples was tested against the Staphylococcus aureus test strain.
