Abstract: The invention is directed to a composite nonwoven fabric (10) comprising a nonwoven web (11) of spunbonded substantially continuous thermoplastic filaments, a nonwoven web (14) of thermoplastic strands, and a nonwoven web (13) of thermoplastic meltblown microfibers sandwiched between the nonwoven web of spunbonded substantially continuous filaments and the nonwoven web of thermoplastic strands. An adhesive agent (12) is disposed between the nonwoven web (11) of spunbonded filaments and the nonwoven web (13) of meltblown microfibers and between the nonwoven web (14) of thermoplastic strands and the nonwoven web (13) of meltblown microfibers, adhering the respective nonwoven webs together to form a unitary composite nonwoven fabric. In a preferred embodiment, the composite nonwoven fabric of the invention comprises a nonwoven web of spunbonded substantially continuous polyamide filaments, a nonwoven web of polyamide strands, and a nonwoven web of polyethylene meltblown microfibers sandwiched between the nonwoven web of spunbonded substantially continuous filaments and the nonwoven web of strands.
