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.
