着することが出来る。The synthetic resin-impregnated paper and the porous reinforcing layer are bonded to the porous body using an adhesive or a heat-sensitive adhesive sheet. It is also possible to use isocyanates as adhesives. The synthetic resin-impregnated knitted layer can also be bonded to the synthetic resin-impregnated paper or the porous reinforcing layer using an adhesive or the synthetic resin impregnated in the knitting layer, and in particular the porous reinforcing layer. In the case of a layer, the knitted layer can be directly bonded to the porous body through the pores of the porous reinforcing layer.

の成形形状に保持する。When a blocked porous body impregnated with polyvalent isocyanate is heated and molded, the bond between the isocyanate group and the blocking agent is dissociated by heating and free isocyanate groups are generated, as described above. The isocyanate compound is polymerized and networked through the isocyanate group, whereby the polyvalent isocyanate is cured and the porous body is held in a predetermined molded shape.
したがって本発明においては成形後の乾燥工程が不要で
