Preparation of Nano-ZnO and Its Application to the Textile on Antistatic Finishing
نویسنده
چکیده
Nano-ZnO was prepared by direct precipitation method with zinc chloride and sodium carbonate anhydrous as raw materials, and its particle size and dispersion were characterized by TEM. The effects of concentration and the ratio of reactants and reaction temperature on its dispersion in aqueous solution were analyzed and the best reaction conditions were as follows: reaction temperature 60 , ultrasonic vibration time 40 min, concentration of the reactant 0.5mol/l and molar ratio of reactants 1:2 for the preparation. The cotton fabric and the polyester fabric which were both finished by pad-dry-cure process with antistatic finishing agent, which was compounded with nano-ZnO, were tested on their antistatic property. According to the comparation between the cotton and the polyester treated fabrics on antistatic property, the results showed that the charge density of the polyester fabric was reduced to 9.5×10 C/m from 5.8×10 C/m, which was about 10 times as that of the cotton fabric.
