Abstract
Nonwoven fabrics including a first outermost spunbond layer, a second outermost spunbond layer, and at least a first meltblown and/or melt-fibrillated layer disposed directly or indirectly between the first outermost spunbond layer and the second outermost spunbond layer. The first outermost spunbond layer comprises a first plurality of continuous fibers that are thermally fused and compacted against one another and define a microporous film on an outermost surface of the nonwoven fabric. The first plurality of continuous fibers comprises a first polymeric composition having a first melting point and the first meltblown layer and/or melt-fibrillated layer comprises a first plurality of meltblown fibers and/or melt-fibrillated fibers comprising a third polymeric composition having a third melting point, in which the first melting point is lower than the third melting point.
