Method for performing ultrasonic nickel activation chemical nickel plating on surface of non-woven fabric by taking sodium borohydride as reducing agent

The invention relates to a method for performing ultrasonic nickel activation chemical nickel plating on the surface of a non-woven fabric by taking sodium borohydride as a reducing agent, and in particular relates to a method for performing ultrasonic nickel activation chemical nickel plating on the surface of the non-woven fabric by taking sodium borohydride as a reducing agent. The invention aims to solve the problem that the production cost is increased as expensive metal palladium is used for activating nickel plating in the conventional method. The method comprises the following steps: 1, preparing the non-woven fabric in the early stage; 2, removing oil from the non-woven fabric; 3, coarsening the non-woven fabric; 4, performing ultrasonic palladium-free activation on the non-woven fabric step by step for multiple times; and 5, chemical nickel plating of the non-woven fabric. The mass content of phosphorus in the plating layer of the nickel-plated non-woven fabric prepared through the method is 10.5%,
