Abstract: The invention is directed to a composite nonwoven fabric comprising a nonwoven web of spunbonded substantially continuous thermoplastic filaments, a nonwoven web of thermoplastic strands, and a nonwoven web of thermoplastic meltblown microfibers sandwiched between the nonwoven web of spunbonded substantially continuous filaments and the nonwoven web of thermoplastic strands. An adhesive agent is disposed between the nonwoven web of spunbonded filaments and the nonwoven web of meltblown microfibers and between the nonwoven web of thermoplastic strands and the nonwoven web 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.

Abstract: A nonwoven filamentary web having high loft is produced by extruding a molten thermoplastic polymer or polymer blend through a spinneret to form continuous filaments while maintaining extrusion conditions which induce melt-fracture of the extrudate; attenuating the thus extruded melt-fractured filaments to obtain filamentary material having a crimped structure; and depositing the melt-fractured filamentary material on a collection surface and forming a web therefrom.

Abstract: PCT No. PCT/US93/00566 Sec. 371 Date Sep. 17, 1993 Sec. 102(e) Date Sep. 17, 1993 PCT Filed Jan. 22, 1993.The invention provides elastic fabrics which are substantially non-extensible in the machine direction and have substantial elastic properties in the cross-machine direction. The process stable fabrics of the invention include a net and a fibrous layer which are secured together. The net is composed of a plurality of continuous machine direction strands and a plurality of cross-direction strands. The machine direction strands are substantially non-extensible and the cross-direction strands are substantially elastic. The fabrics of the invention can be manufactured and processed more readily than fabrics which are elastic in both the machine direction and the cross-machine direction.

Abstract: COMPOSITE ELASTIC NONWOVEN FABRIC of the Invention The invention provides composite elastic nonwoven fabrics and the process of making them. The composite elastic fabrics of the invention include an elastomeric net and at least one fibrous web including binder fibers and which is intimately hydroentangled with the elastomeric net. At least a portion of the binder fibers in the hydroentangled fibrous web have been thermally activated thereby bonding the hydroentangled web into a coherent, substantially unitary structure encompassing the elastomeric net.

Abstract: A nonwoven fibrous web is disclosed having high wet tensile strength when packed in a preservative liquid load, yet which breaks up under mild agitation conditions in a wet environment such as by the flushing action of a toilet. The wiper includes a nonwoven web made of a special blend of cellulosic fibers held together only by friction and naturally occurring hydrogen bonding. No binder is necessary to hold together the fibers. Derivatization of the fibers is not necessary for their breakapartability. The nonwoven fibrous web is produced by subjecting a wet-laid web of cellulosic fibers to hydroentanglement and drying the web without addition of a bonding agent.

Abstract: The invention is directed to nonwoven fabrics including at least one fibrous web (12) which preferably includes staple or natural fibers, having a bonding layer (22) of thermoplastic material disposed primarily within a substantially discrete cross-sectional portion of the web and below at least one surface of the web. The layer (22) of bonding material comprises a thermally fused thermoplastic web derived from a layer of thermoplastic meltblown fibers. The layer (22) of bonding material can be an elastomeric layer or a non-elastomeric layer thus providing a fabric having elastic or non-elastic properties. The bonding layer adds strength and optionally elastic properties, to the fabric and anchors fibers of the fibrous layer in the fabric. Advantageously, the fabric of the invention is made by hydroentangling a layered web including a first fibrous layer and a layer of meltblown fibers and thermally treating the hydroentangled layered web sufficiently to fuse the thermoplastic meltblown fibers.
