A chemical method of silver plating for organic fibre is carried-out as to make raw material pretreatment with washing in the ultrasonic washer in acetone solution, surface activation treatment with nitric acid solution and chlorohydric acid solution, sensitizing with SnCl2 sensitizer and catalyzing with PdCl2 catalyst. The products made with the present invention has an uniform surface, low rateof electricity resistance and high adhesion ability. The softness and flexibility of the conductive fibre is nearly as the same as the raw material fibre.
