摘要：
A nonwoven laminate fabric includes first and second nonwoven webs formed of spunbonded substantially continuous filaments and a nonwoven web of meltblown microfibers having a basis weight between about one and twenty grams per square meter sandwiched between and bonded to the first and second nonwoven webs to form a composite nonwoven fabric. The meltblown web includes a plurality of thermoplastic microfine fibers having an average fiber diameter of less than 1.5 microns. The nonwoven laminate exhibits good barrier properties and can be used as a sterile wrap.
