Abstract:

The present invention provides absorbent structures for absorbent articles, in particular catamenial pads, that are capable of acquiring, distributing, and storing aqueous body fluids, especially menstrual fluids, as well as providing better fit and comfort for the user of the products. These absorbent structures comprise an absorbent core and a comparatively low density, fluid-pervious, resilient web in fluid communication with the absorbent core. The resilient webs of the present invention are formed from a thermally-bonded matrix predominantly comprised of synthetic fibers which maintains substantially constant resiliency and density properties even after exposure to aqueous bodily fluids. The advantageous aspects of absorbent structures of the present invention include: (a) maintenance of a comparatively low density structure to aid in handling of fluids under "gush" situations; (b) the ability to increase total fluid capacity and retain the absorbed fluid, i. e. , reduce "rewet", by increasing the utilization of absorbent gelling material; and (c) reduced panty and body soiling because of the improved flexibility and resiliency of the resilient webs, even when wetted and compressed during use, and hence consistent area coverage during use.
