Abstract:
A laminated nonwoven fabric of multi-layer structure comprising a composite spun bonded nonwoven fabric laminated on a composite meltblown extra-fine-fiber nonwoven fabric having an average fiber diameter of 10 .mu.m or less; whereinthe composite spun bonded nonwoven fabric comprises a composite continuous fiber composed of a low melting point resin and a high melting point resin, the difference in melting point between the low melting point resin and the high melting point resin being at least 10.degree. C., the low melting point resin forming at least a portion of the surface of the fiber, and the composite spun bonded nonwoven fabric being a thermal fusion product of the composite continuous fibers by the mediation of the low melting point resin,the composite meltblown extra-fine-fiber nonwoven fabric comprises composite meltblown extra-fine fibers composed of a low melting point resin and a high melting point resin, the difference in melting point between the low melting point resin and the high melting point resin being at least 10.degree. C., the low melting point resin forming at least a portion of the surface of the fiber, and the composite meltblown extra-fine-fiber nonwoven fabric being a thermal fusion product of the extra-fine fibers by the mediation of the low melting point resin; andthe composite spun bonded nonwoven fabric and the composite melt-blown extra-fine-fiber nonwoven fabric are integrated by fusion of the low melting point resin of the composite spun bonded nonwoven fabric and/or the low melting point resin of the composite meltblown extra-fine-fiber nonwoven fabric.
