The invention provides a preparation method of a stainless steel wire for netting. The preparation method comprises the following steps that the pass deformation in a metal wire drawing procedure is reasonably arranged, the procedures of rough drawing, primary annealing, fine drawing and secondary annealing are carried out, a water-based lubricant is adopted in the last pass in fine drawing, and a lubricant on the surface of a semi-finished product wire is removed. The purpose that the stainless steel wire for netting can be obtained through two times of drawing-annealing is achieved, the produced stainless steel wire is smooth and clean in surface, it is guaranteed that the physical and chemical properties of the wire rod are flush with those of other processes while the technological process is shortened, the using effect is stable, the production process is shortened, economic benefits are good, and the stainless steel wire is suitable for industrial production and use.
