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.

Absorbent articles having improved separator layer

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.

Absorbent core for absorbing body liquids and method

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.
