(57) [Abstract] [Purpose] In urethane foam molding, especially when molding urethane foam molded articles, by preventing excessive urethane impregnation and filling, it is possible to prevent deterioration of rigidity and also prevent abnormal noise from occurring. Reinforcement base fabric for urethane foam molding, such as vehicle seats, which can provide the required urethane and base fabric integrity as a molded product by appropriate urethane impregnation and filling, and its manufacturing method, and high-performance moldable polyurethane seat using the same To provide cushioning material. [Structure] When manufacturing an in-mold foam molded article, a basis weight 20 To to dense nonwoven fabric 2 and the basis weight of 30 to no porosity 87 91% at 100 g / m 2 porosity at 300 g / m 2 9 0 to 94% bulky nonwoven fabric 1 is laminated and integrated, Reinforcing base fabric for urethane foam molding, which is formed by supplying a foamable urethane liquid to the dense non-woven fabric side, infiltrating urethane into the dense non-woven fabric layer for foaming and reinforcing, and integrally forming with the polyurethane foam 4 to be formed. And a method of manufacturing the same and a moldable polyurethane cushion material for a seat. |
