Abstract
The present invention relates to composite absorbent structures suitable for incorporation into absorbent articles such as sanitary napkins, diapers, incontinent devices, training pants and the like. Such structures comprise webs of entangled blown microfibers, substantially nonabsorbent crimped staple fibers, a fluid control system comprising hydrophilic particulate entities and also optionally containing certain types of hydrogel-forming polymeric gelling agent particles, and a hydrophilizing agent. Such composite web structures of this construction have especially desirable comfort, integrity and fluid handling characteristics.
