Nano ZnO crystal in-situ growth on SiO2 nano sol-coated cotton fabric via a reaction between Zn(NO3)2 and (CH 2)6N4 through a low-temperature hydrothermal method was studied. The effects of hydrothermal reaction conditions and SiO 2 nano sol coating on the size and crystalline perfection of nano ZnO, and the UV protection property of the fabric were investigated. The optimal treatment conditions for the highest Zn content and the best ZnO crystalline perfection on the fabric surface were obtained. Under optimal conditions, the cotton fabric was covered with 25 to 30 nm diameter ZnO crystallites and had an excellent UV-blocking property.
