Synthesized and commercial titanium dioxide (TiO2) were coated onto household curtain fabrics for anti-microbial and ultraviolet (UV) shielding functions. The coating was performed by inducing a deposition of the TiO2 layer from the Ti precursor onto the fabric surface. A silane adhesive agent was employed to improve the adhesion between the coating and the fabric. Ag nanoparticles were also incorporated into some samples to further improve the anti-bacterial activity, which was evaluated by a standard qualitative test (AATCC 147). Efficiency for UV shielding was evaluated by measuring a UV–visible reflection of the coated fabrics both before and after subjecting it to several washing cycles. The results showed that the TiO2-coated fabrics had potential as both anti-bacterial and UV shielding for the curtain industry. [ABSTRACT FROM AUTHOR]
