    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 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: 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.
