(57) [Summary] (Correction) [Purpose] Satisfies urethane barrier properties, noise prevention, and moldability, and imparts strong urethane and base fabric integrity after molding to improve the urethane reinforcing effect. Provided are a urethane foam molding reinforcement for large vehicle seats and the like, a noise preventing base cloth, a method for producing the same, and a high-performance moldable polyurethane sheet material using the same. [Structure] When manufacturing an in-mold foam molded article, a basis weight 30 To 200 g / m 2 and upper and lower bulky non-woven fabric layers 1 and 3 having a porosity of 90 to 94% and a basis weight of 20 to 100 g / m 2 dense to no porosity 87 91% in a non-woven layer 2 Is laminated and integrated as an intermediate layer, and a foamable urethane liquid is supplied to the bulky non-woven fabric layers 1 and 3 side to permeate urethane into the non-woven fabric layer for foaming and reinforcement, and a polyurethane foam 5 formed. To be integrated with. |
