In the present study zinc oxide (ZnO)nanoparticles which has many unique physical and chemical properties prepared by precipitation method using different concentrations of ZnO (1%, 3% and 5%) also using polyvinyl pyrrolidone(PVP) with different concentration (1% and 3%) as a binder and dyed (reactive dye). These nanoparticles have average size of 37-58 nm. It coated the bleached cellulosic fabric plain weave such as Giza80, Giza90 (100%cotton) and blended fabric (65/35%) with polyester. The results of this study found that the concentration of 3:3 of ZnO nanoparticles and PVP coated fabric was significantly higher than the control for the physical properties such as tensile strength, elongation, color strength (K/S) and evaluate wash fastness also characteristic size of ZnO NPS and the crystallinity of fabric by Fourier transmission infra red (FTIR), Scanning electron microscope (SEM) and X ray diffraction (XRD). The result also showed that the concentration of ZnO nanoparticles increased the crystallinity index also increased ZnO/PVP elevated UV protection in all varities. The highest response was G90 and G80followed by G70 blended with poly-ester. ZnO/PVP increased the antimicrobial activity against E.coli and S. aureus compared with the bleached fabric which killed about 99.8% of the bacterial cells. In conclusion by the present studies, it can be produced textiles had appearance on the surface textiles in dying process, UV protection and antimicrobial activity to use in medicine works
