The invention relates to an energy-increased spun-bondedfilter material containing polypropylene/polyester and a preparation method of the energy-increased spun-bonded filter material. The filter material comprises three layers of fiber meshes bonded together, wherein the fiber meshes comprise a coarse-denier fiber mesh, an intermediate-denier fiber mesh and a fine-denier fiber mesh sequentially; fibers in the fiber meshes are sheath-core composite fibers; the coarse-denier fiber mesh, the intermediate-denier fiber mesh and the fine-denier fiber mesh are spun sequentially, stacked, then bonded for reinforcement and subjected to polished roller hot rolling, corona processing of electrets and winding, and the energy-increased spun-bonded filter material containing polypropylene/polyester double components is obtained. The filter material has fluffy and soft structure and high filter efficiency while maintaining lower resistance. Besides, the preparation method is environment-friendly, simple and feasible in process and suitable for industrial production.
