Abstract
Creped absorbent composites made from lightly crosslinked or water-swellable hydrophilic polymers with layers of wicking substrates are disclosed. The creped composites are made by drying the composites to less than 8% moisture and creping them in a creping zone. The creped composites have a tissue-like feel at low relative humidities with rapid absorption and are useful to make low bulk, high fluid capacity personal care products. Absorbent pads made from the above composites are also disclosed wherein the pads comprise one or more layers of wicking substrates, a water impermeable bottom sheet, and a water permeable face sheet.
