Functionalization of the textile surface plays a remarkable role in the synthetic fiber industry. This research isinterested in the one-step simultaneous functional finishing and transfer printing of alkaline-activated polyester fabric usingC.I. Disperse Red 60 and C.I. Disperse Blue 56. The optimum color depth was achieved using zinc oxide nanoparticle 0.5 %and nano polyurethane (50 g/l) in the finishing bath formulation, additionally, excellent ultraviolet protection (50+) category. Zinc oxide nanoparticles and zinc oxide/polyurethane nanocomposite finishing showed high antimicrobial efficiency. Theyshowed a microbial reduction of C. albicans (97 %), E. coli (93 and 96 %), and S. aureus (88 and 93 %), respectively. Thefinished polyester fabrics showed significant durability of protective properties for washing cycles after 25 washes. Theultraviolet protection maintained excellent category and enhanced ultraviolet protection factor values. The antimicrobialactivities after 25 washes achieved sustained microbial reduction percentage against the three tested microorganisms (C. albicans 92 and 87 %; E. coli 90 and 92 %; and S. aureus 87 and 81 %). The results showed the positive impact of zinc oxidenanoparticles and zinc oxide/polyurethane nanocomposite finishing on fastness to sublimation and light. At the same time,there is no change in the fastness of washing and perspiration. The effect of finishing formulations on the finished polyesterfabric samples' crucial mechanical properties was studied. These properties were fabric weight, thickness, tensile strength andelongation, and abrasion resistance. The obtained results showed that finishing polyester fabric samples with nanopolyurethane, zinc oxide nanoparticles, or zinc oxide/polyurethane nanocomposite did not alter the essential mechanicalproperties required for polyester fabric applications in textiles and apparel for different end uses. Additionally, the polyesterfabric surface was characterized using scanning electron microscopy and Fourier transform infrared spectroscopy, improvingthe functional finishing.
