摘要： A nonwoven fabric having high performance aqueous fluid retention and wiping characteristics and a method of producing such fabric. The fabric comprises a reinforcing web of self-bonded continuous filament synthetic fibers having at least one surface with spaced clusters of synthetic staple fibers and short natural fibers generally surrounded by void areas having a concentration of synthetic staple fibers and short natural fibers which is lower than such concentration in the clusters. The desired pattern of clusters may be obtained by hydroentanglement using a coarse apertured forming surface.

摘要： The invention is directed to a composite nonwoven fabric comprising first and second nonwoven webs of spunbonded substantially continuous thermoplastic filaments, and a nonwoven hydrophobic microporous web of thermoplastic meltblown microfibers sandwiched between the first and second nonwoven webs. The filaments of the nonwoven spunbond webs are formed of continuous multiconstituent filaments which include a lower melting gamma radiation stable polyethylene polymer component and one or more higher melting gamma radiation stable polymer constituents, wherein a substantial portion of the surfaces of the multiconstituent filaments consists of the lower melting gamma radiation stable polyethylene constituent. The nonwoven hydrophobic microporous web is formed from a gamma radiation stable polyethylene polymer. The webs are bonded together to form the composite nonwoven fabric by discrete point bonds in which the polyethylene constituent of said multiconstituent filaments and the polyethylene of said third nonwoven web are fused together.

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.
