ABSORBENT CORE STRUCTURES HAVING UNDULATIONS

摘要

An absorbent core structure having at least one acquisition region, at least one distribution region, and at least one storage region. The acquisition region being constructed from a fibrous material. The acquisition region having a relatively low density from about 0.018 g/cc to about 0.20 g/cc. The distribution region being constructed from said fibrous material. The distribution region being consolidated to have a relatively medium density from about 0.024 g/cc to about 0.45 g/cc. The distribution region being in fluid communication with said acquisition region. The storage region being constructed from said fibrous material. The storage region being consolidated to have a relatively high density from about 0.030 g/cc to about 0.50 g/cc. The storage region being in fluid communication with said distribution region. A portion of the fibrous material being formed into at least one peak and at least one valley and then subsequently folded in order to form said absorbent core structure.
