Abstract: The invention is directed to composite nonwoven fabrics comprising a hydrophobic nonwoven web, a nonwoven web of thermoplastic meltblown microfibers and a hydrophilic nonwoven web comprising staple fibers. The nonwoven web of thermoplastic meltblown fibers is sandwiched between the hydrophobic nonwoven web and the hydrophilic nonwoven web and all of the layers are thermally bonded together via discontinuous thermal bonds distributed substantially throughout the composite nonwoven fabric.

Abstract: A slot draw attenuator apparatus and method are provided for producing webs of spunbonded thermoplastic filaments having improved cover even at low basis weights. The filaments are introduced to a slot draw attenuator having corona electrodes mounted in an elongate insulator bar and staggered and spaced along one wall of the attenuator slot near the exit end thereof. The corona electrodes are electrically connected to a high voltage source. The opposing wall of the slot is grounded. A corona is created in the attenuator slot so that the filaments are charged as they exit the attenuator. The electrostatic charge induces repelling forces in the filaments so that the filaments spread before they are randomly deposited upon a forming belt.

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.
