Absorbent webs having improved fluid acquisition and retention properties ar e disclosed. The present invention further relates to absorbent articles such as sanitary napkins, diapers, adult incontinence pads and briefs, panty liners, tampons, and the like, incorporating such webs (such as for an absorbent core). The fibrous absorbent web of the present invention is an airlaid fibrous web which includes a substantially uniform admixture of hardwood pul p fibers (such as encalyptus fibers) and softwood pulp fibers (such as souther n softwood kraft fibers). Preferably, the fibrous absorbent web also incorporates superabsorbent material throughout the web. The fibrous web lay er may also incorporate a binder material such as bicomponent binder fibers in the uniform admixture of fibers described. One or more webs of the present invention may make up the absorbent core of a disposable absorbent article. The web layer of the present invention provides high capillary pressure and improved fluid distribution. Additionally, because of its airlaid nature, it is possible to incorporate superabsorbent material throughout the web and to achieve improved stiffness control over the resulting web as compared to previous webs.
