PURPOSE: To obtain a laminated nonwoven fabric, capable of eliminating problems in the laminated nonwoven fabric in which a melt blown nonwoven fabric is laminated to layers of a spunbonded nonwoven fabric, excellent in water and fluffing resistance and having higher barrier properties for fine dust and blood and a method for producing the nonwoven fabric.
CONSTITUTION: This laminated nonwoven fabric excellent in water and fluffing resistance and barrier properties for fine particles is characterized by comprising a laminate of a layer 2 of a melt blown nonwoven fabric produced by melt blowing and layers (3a) and (3b) of spunbonded nonwoven fabrics and making a filling layer 4 present on at least one surface of the laminate by fusion of mutual single fibers. Furthermore, a method for producing this laminated nonwoven fabric is provided.
