Abstract

Disclosed are absorbent structures having y-directional profile in density and superabsorbent polymer particle content. The structures include zones having higher density and higher superabsorbent polymer particle content and zones having lower density and lower superabsorbent polymer particle content. Also disclosed are methods for preparing absorbent structures having y-directional profile in density and superabsorbent polymer content.
