Abstract

The invention discloses a method for preparing a titanium dioxide nanoparticle composite silver plating on the surface of a polyester fabric. The method comprises the following steps: firstly preprocessing the polyester fabric; and secondly preparing the titanium dioxide nanoparticle composite silver plating on the surface of the polyester fabric. The method has the following beneficial effects: based on the traditional chemical silver plating process, aiming at the defect of high possibility of agglomeration of the titanium dioxide nanoparticles, a dispersing agent is used for carrying out ultrasonic dispersion on the titanium dioxide nanoparticles and then the titanium dioxide nanoparticles are added to the chemical silver plating solution to carry out titanium dioxide nanoparticle composite chemical silver plating on the polyester fabric under the condition of ultrasonic waves, thus not only improving the wear resistance of the chemical silver plated polyester fabric but also endowing the chemical silver plated fabric with photocatalytic activity.
