Abstract: An absorbent article such as a diaper has an outer layer of a porous fabric and an inner absorbent core. A separator layer of thermally bonded nonwoven fabric is positioned between the outer layer and the core to minimize rewet by liquids. The fibers of the nonwoven fabric of the separator layer have a diameter greater than 28 microns, and at least 5 crimps per extended inch, and the fabric has a porosity of about 90-95%, to provide superior rewet properties.

Abstract: The disclosure describes an absorbent core, free of wood pulp or other cellulosic materials. The core includes two thin outer layers, with at least one layer being porous and receptive to body liquids. A quantity of superabsorbent polymer particles of a particular type is provided between the outer layers and is loosely contained in individual unbonded open zones or flat closed pockets defined by a plurality of intersecting heat bond lines between the layers, with the lines defining a densified and a hot calendar-bonded fiber structure to provided wicking lines or flow zones between the pockets. The dry product is a flat, thin partial laminate.

Abstract: An absorbent article such as a disposable diaper or sanitary article has an absorbing core and an outer porous cover sheet to allow transfer of liquids through the cover sheet and into the core. A liquid transfer sheet in the form of a nonwoven fabric is located between the cover sheet and the core. The transfer sheet has at least two layers, with the layer facing the cover sheet having relatively coarse fibers, and the layer facing the core having relative fine fibers. The arrangement allows more efficient transfer of liquids to the core while minimizing wetback.

Abstract: An absorbent article has an absorbent core and a liquid permeable top sheet made of polyolefin material. An acquisition layer is provided between the top sheet and the core. The acquisition layer is a nonwoven fabric made from polyolefin fibers bonded by a cured resin. The acquisition layer has a larger pore size than the top sheet and is treated with a surface active agent to render it hydrophilic.

Abstract: A heat shrinkable nonwoven fabric includes outer layers of thermoplastic staple fibers and an inner layer containing heat shrinkable fibers the layers are point bonded together at spaced locations without causing shrinkage of the heat shrinkable fibers. The web may then be uniformly heated in a relaxed state to cause a substantial increase in bulk.
