Abstract

PURPOSE:To obtain a solid-form cushion material simply and inexpensively by a method wherein slab urethane to which a surface-processing agent of resin having a property of being melted and set is applied is put into molding dies and heated under pressure and thereby the surface-processing agent is melted and set. CONSTITUTION:On the occasion that slab urethane formed of polyurethane form is molded into a desired solid form as a cushion material and the like, the slab urethane 1 is cut in a desired shape and the front or back surface or both surface thereof are coated with the surface-processing agent 2 of resin having a property of being melted and set. Next, the slab urethane is inserted into a pair of male and female molding dies 3 and 4 in a desired shape and pressed and heated. By this processing, the surface processing agent 2 of resin applied on the slab urethane 1 is melted and softened, penetrates into the slab urethane 1 and then is set, forming the aimed cushion material 5 along the shape of the surface of the molding dies 3 and 4.
