Fabrication of high UV-shielding cotton fabric via nanosized TiO2 coating
Nanosized TiO2 was prepared using Tetrabutyl titanate as a precursor by sol-gel process. Lightweight 100% cotton fabric was successfully modified by the as-obtained nanosized TiO2 coating to impart high ultraviolet (UV) shielding property to the fabric surface. Cotton fabrics were treated by dipping them in nanosized TiO2 dispersion solution and ultrasonic-treating at room temperature for 15min, drying at 80℃ for 6min and curing at 150℃ for 3min. Scanning electron microscopy (SEM) showed the formation of nanosized TiO2 particles or clusters on the fiber surface. Excellent UV-shielding property was obtained with all treated fabrics. Increasing titania content in the dispersion solution led to increased UV-shielding effect, which could be attributed to the increase of the refractive index of the nanosized TiO2 particles on the fabric surface. Good washing durability was obtained, which indicated a good adhesion between the coating and the fabric surface.
