Disclosed is a production method of polypropylene spunbonded hot wind consolidation geotextile. The production method comprises the following steps of 1, preparing material; 2, conveying, melting andextruding raw material; 3, filtering and spinning; 4, crow air blowing cooling; 5, air drafting; 6, carrying out electrostatic devillicate and pendulum wire; 7, lapping; 8, pre-hot-rolling, and performing hot wind consolidation; 9, trimming and rolling; 10, inspecting and packing; 11, packing. The production method of the polypropylene spunbonded hot wind consolidation geotextile overcomes some disadvantages of needle-punched nonwoven fabric. Moreover, a polypropylene raw material is used, and the geotextile has the advantages of being good in air permeability, water permeability and rigidity,foldable, smooth in surface, good in compactness, free of any chemical bonding agents, more acid and alkali resistant, corrosion resistant, mothproof, antioxidative and the like, which makes the geotextile a quite ideal geotextile material.
