PROBLEM TO BE SOLVED: To provide a laminated nonwoven fabric which can be efficiently produced even when a production process of a nonwoven fabric or a nonwoven web is separated from an integration process by entanglement using a high-pressure liquid flow, and which is improved in dimensional stability and mechanical strength by taking advantage of a filament nonwoven fabric.SOLUTION: A laminated nonwoven fabric comprises a filament nonwoven fabric and a staple fiber nonwoven web which are integrated by lamination. The filament nonwoven fabric is produced by heat-bonding and thereby integrating a machine direction web in which filaments are substantially arranged in a direction orthogonal to a width direction and a width direction web in which filaments are substantially arranged in the width direction. In addition, the filaments constituting the machine direction web are integrated by heat in such a state that the plural filaments are bundled together. The staple fiber nonwoven web is laminated only on the width direction web surface of the filament nonwoven fabric and is lamination-integrated therewith at least by entanglement of staple fibers constituting the staple fiber nonwoven web with the filament nonwoven fabric. |
