Abstract

In an absorbent article comprising a liquid-permeable topsheet, a liquid-impermeable backsheet, and an absorbent structure positioned between the topsheet and the backsheet, the absorbent structure includes an upper layer, a lower layer, and an elongate, absorbent core, which is formed from cellulosic fibers and from distributed particles of a superabsorbent polymer (SAP) and which has an elongate, central portion with an absorbency under load (AUL) not less than about 12 grams/gram. The absorbent core has a front end, a back end, and two ears projecting from the elongate, central portion, near the front end with the superabsorbent polymer (SAP) at an upper surface in essentially no concentration and at each of the ears in a concentration that is about one half of the concentration along the elongate, central portion. Being formed from polyester, polyolefinic, cellulosic, conjugate, or mixed fibers, the upper layer is capable of absorbing some of a liquid permeating the upper layer from the topsheet and of transferring to the upper surface of the absorbent core some of the liquid permeating the upper layer from the topsheet. Having a basis weight not more than about 150 grams per square meter and an absorbency under load (AUL) not more than about 6 grams/gram, the lower layer has a minimal absorbency but is capable of transferring to a lower surface of the absorbent core a liquid permeating the lower layer from the absorbent core.
