PURPOSE:To produce a reinforcing and unpleasant sound preventing base fabric for urethane foam molding such as a sheet for a vehicle having high urethane reinforcing effect satisfying urethane barrier properties, unpleasant sound preventing properties and moldability, imparting the strong integration of urethane and a base fabric after molding and having high urethane reinforcing effect and to provide a high capacity moldable polyurethane sheet material using the base fabric. CONSTITUTION:At the time of production of an in-mold foamed molded object, bulky nonwoven fabric layers 1, 3 with a wt. basis of 30-200g/m2 and voids of 90-94% are used as upper and lower layers and a dense nonwoven fabric layer 2 with a wt. basis of 20-100g/m2 and voids of 87-91% is used as an intermediate layer and all of the layers are integrally laminated and a foamable urethane soln. is supplied to the bulky nonwoven fabric layers 1, 3 to be infiltrated in the nonwoven fabric layers and foamed to reinforce the nonwoven fabric layers to integrate the fabric layers with the formed polyurethane foam 5.
