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.

Multilayer nonwoven fabric for foam molding

There is provided a nonwoven fabric excellent in the balance among fuzz resistance, softness and tensile strength. The nonwoven fabric comprises an embossed portion and a non-embossed portion; the embossed portion comprising an emboss pattern that comprises unit patterns each delimited by emboss lines; the emboss lines each comprising a plurality of emboss element parts that are continuously arranged with a predetermined interval; wherein in the direction in which the distance from any arbitrarily-defined point in the non-embossed portion within the unit pattern toward the outside of the emboss lines that delimit the non-embossed portion is shortest, at least one of the plurality of emboss element parts is disposed so as to block the direction in which the distance from the arbitrarily-defined point toward the outside of the emboss lines that delimit the non-embossed portion is shortest.

Nonwoven fabric

Disclosed is a multilayer nonwoven fabric for foam molding containing a dense layer and a reinforcing layer provided on at least one side of the dense layer, the reinforcing layer is a staple fiber nonwoven fabric containing thermoplastic resin staple fibers (A) having a fiber diameter of more than 20 &#x3bc;m, in an amount of 5% by mass to 50% by mass, and hermoplastic resin staple fibers (B) having a fiber diameter of 20 &#x3bc;m or less, in an amount of 95% by mass to 50% by mass, and conjugate polyester-based staple fibers (C) are contained in an amount of 10% by mass to 40% by mass, the dense layer is a nonwoven fabric having bulk density in a range of from 0.05 g/cmto 0.3 g/cm, and the dense layer and the reinforcing layer are entangled with each other by needle punching.
