Multilayer nonwoven fabric for foam molding, method of producing multilayer nonwoven fabric for foam molding, urethane-foam molded complex using multilayer nonwoven fabric, vehicle seat, and chair
Abstract:
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 μm, in an amount of 5% by mass to 50% by mass, and hermoplastic resin staple fibers (B) having a fiber diameter of 20 μm 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/cm3 to 0.3 g/cm3, and the dense layer and the reinforcing layer are entangled with each other by needle punching.
