The invention discloses a preparation method of a static loaded multi-coating yarn or fabric material. The preparation method is characterized by including the following steps that 1), a yarn or fabric substrate material is put in a dopamine treatment bath to be treated, the material is washed and dried after being treated, and the yarn or fabric substrate material with a poly-dopamine binding layer is obtained; 2), the yarn or fabric substrate material with the poly-dopamine binding layer is put in a silver ammonia solution, a reducing agent solution is dropwise added into the silver ammoniasolution to be treated, the material is washed and dried after being treated, and the yarn or fabric substrate material with the binding layer and an electric conductance layer is obtained; 3), the yarn or fabric substrate material with the binding layer and the electric conductance layer is treated in a power storage polymer solution, then the redundant solution is removed through a roller, the material is dried, and the yarn or fabric substrate material with the binding layer, the electric conductance layer and a power storage layer is obtained. On the basis of the basic decorating and beautifying functions of textiles, the additional functions of the textiles are further improved, and functionalization development of the textiles can be promoted.
