Abstract: The cotton fabric was finished by modified TiO₂ nanowires for anti-ultraviolet and self-cleaning function. The results showed that the performance of anti-ultraviolet and self-cleaning was very good on the finished cotton fabric. The value of UPF reached 77.21, and the average transmittance of UVA and UVB arrived at 11.04%, 0.41%, respectively. After being soiled by chili oil and irradiated in ultraviolet light of 24 W for 7 hours, the fabric cleaned the surface stains by itself. As the surface of modified TiO₂ nanowires was imported plenty of active functional groups, resulting in integrating to textile fiber by chemical bond. So that the finished cotton fabric showed durable washing resistance.

Key words: TiO₂ nanowire; cotton fabric; anti-ultraviolet; self-cleaning
