Patent ID: 10967607

Abstract:
An object is to realize a base material nonwoven fabric for molding excellent in handling as a material, by preventing peeling between laminated components constituting the base material for molding; and even after the base material is reheated and molded, to provide a molded product having excellent elasticity resistant to external forces such as flying debris or the like, and while maintaining peeling resistance, capable of realizing excellent sound absorbing characteristics, by suppressing air permeability inhibition due to the adhesive component. A base material nonwoven fabric for molding in a predetermined shape by heat molding, characterized by having a two-layer structure of a long fiber nonwoven fabric layer comprising at least a polyester resin and a short fiber nonwoven fabric layer comprising a polyester resin, wherein a flow-solidified undrawn polypropylene layer is localized in the vicinity of an interface between the long fiber nonwoven fabric layer and the short fiber nonwoven fabric layer.
