ABSTRACT:
The present invention relates to absorbent web structures suitable for incorporation into absorbent articles such as sanitary napkins, diapers, incontinent devices, training pants and the like. Such structures comprised webs of entangled melt blown microfibers which are prepared from a particular type of hydrophilic nylon copolymer. Preferred hydrophilic cylon microfiber-based webs also contain staple fibers and/or particles of hydrogel-forming polymeric gelling agent. Web structures containing hydrophilic nylon microfibers have specially desirable comfort, integrity and fluid handling characteristics.
