Abstract

Multilayer nonwoven fabrics for foam molding that have excellent resistance to the separation of layers, have reinforcing effects and urethane leakage prevention performance, and are producible without the occurrence of fiber dust on the surface. In the multilayer nonwoven fabric for foam molding, a reinforcing layer is stacked on at least one side of a dense layer, the dense layer includes a meltblown nonwoven fabric layer (A) and spunbonded nonwoven fabric layers (B) that are stacked on both sides of the layer (A), and the meltblown nonwoven fabric layer (A) and the spunbonded nonwoven fabric layers (B) are partially thermocompression bonded with each other.
