ABSTRACT:
The invention is directed to composite nonwoven fabrics comprising a hydrophobic nonwoven web, a nonwoven web of thermoplastic meltblown microfibers and a hydrophilic nonwoven web comprising staple fibers. The nonwoven web of thermoplastic meltblown fibers is sandwiched between the hydrophobic nonwoven web and the hydrophilic nonwoven web and all of the layers are thermally bonded together via discontinuous thermal bonds distributed substantially throughout the composite nonwoven fabric.
