N2 - To defend against the impact of ultraviolet (UV) irradiation from daily life and even changes in climate and stratospheric ozone, wearing UV-protective clothing is a simple and effective approach to reduce risks to human health from excessive UV exposure. However, normal clothes with traditional dye or additional modifications have limited UV-blocking activity and low washing fastness, bringing huge pressure on the environment. Herein, we applied a bio-interfacial material, tannic acid, to enhance the π interaction for better reusability of the nanostructured zinc oxide (ZnO) modified highly-improved-UV-protective natural textiles, which ultraviolet protection factor (UPF) maintained 309 despite 50 washing cycles. Moreover, the UV-protective properties of cotton-based or wool-based samples have both been significantly enhanced to UPF 500, which increased up to 4200 % compared to the previous metal salt ultraviolet screening agent method. Additionally, the endowed UV-protective characteristic contributed to tensile mechanical properties of modified wool textiles even after 120-hour UV irradiation. This biomass-inspired interface facilitated in-situ synthesis method suggested a promising strategy to take full advantage of the inner and outer walls of natural hollow fibre substrates to deposit active materials for advanced protective textiles.
