摘要:
A laminated nonwoven fabric having a good texture, providing no rough touch, and having a high strength and a large delamination strength are provided. A nonwoven fabric of a multi-layer structure comprises (a) a composite spun bonded nonwoven fabric composed of a low melting point resin component and a high melting point resin component and (b) a composite melt blown extra-fine-fiber nonwoven fabric having a fiber diameter of 10 &mgr;m or less and being composed of a low melting point resin and a high melting point resin; both of the nonwoven fabrics are laminated, and the fibers in each of the nonwoven fabrics and both of the nonwoven fabrics are thermally fused. A method of manufacturing a nonwoven fabric having a multi-layer structure comprises laminating each of the nonwoven fabrics in a multi-layer structure and heating the laminate at a temperature higher than the thermal fusion temperature to cause thermal fusion of the both layers.
