Manufactured by. For example, in the case of a combination of ginseng and slab urethane, the slab urethane and the gauze are attached to the inner surface of the foaming pot in this order, and then the urethane liquid is injected, followed by foaming.

泡成形物の剛性が低いという問題がある。At this time, if the rigidity of the reinforcing material is insufficient, the reinforcing material sags, it takes time to attach the reinforcing material to the mold, and the reinforcing material is partially broken due to the sag. I have a problem. Further, since the coarse blanket has coarse meshes, there is a problem that the urethane liquid escapes and blocks the air vent hole of the foam pot. On the other hand, in the case of the combination of ginseng and slab urethane, the slab urethane layer can prevent the exudation of urethane liquid from the ginseng, but there is a problem that the obtained urethane foam molded article has low rigidity.

レタン発泡成形用被覆材基布が提案されている（実公昭
６２−２６１９３号公報）。For the purpose of increasing the rigidity of the foamed molded article, there has been proposed a urethane foam molding covering material base cloth using a non-woven fabric having a two-layer structure of a high basis weight layer and a low basis weight layer (Jitsuko Sho 62-26193).

擦による異音を発生するという問題がある。However, since the covering material base material for foam molding of this two-layer structure has a low basis weight and a low density of a dense layer, its rigidity is still insufficient, and slack occurs when it is attached to the foam molding pot, so that the molding is performed. There is a drawback that the product wrinkles and it takes time to install. Also, since it is not possible to effectively prevent the urethane resin liquid for foam molding from penetrating the nonwoven fabric, if the urethane resin liquid that permeates the nonwoven fabric oozes onto the surface of the reinforcing material and is foam cured, There is a problem in that the cured polyurethane foam comes into contact with a metal fitting such as a vehicle mounting metal fitting to generate abnormal noise due to friction.
