ABSTRACT:
A nonwoven fabric includes a first composite layer that includes from about 50% to about 90% by weight non-thermoplastic absorbent staple fibers and from about 10% to about 50% by weight thermoplastic fibers. A preponderance of the fibers at a first outer surface of the first composite layer comprise non-thermoplastic absorbent staple fibers and a preponderance of the fibers at a second outer surface of the first composite layer comprise thermoplastic fibers. The nonwoven fabric further includes a second composite layer that includes from about 50% to about 90% by weight non-thermoplastic absorbent staple fibers and from about 10% to about 50% by weight thermoplastic fibers. The second composite layer is adjacent the second outer surface of the first composite layer. The nonwoven fabric further includes bonded regions wherein a portion of the thermoplastic fibers of the first composite layer are fused to a portion of the thermoplastic fibers of the second composite layer, and further wherein the bonded regions have a plurality of contiguous voids.
