Abstract
An absorbent product comprising a topsheet, a secondary absorbent layer, a primary absorbent layer and a backsheet is disclosed. The topsheet preferably is apertured and has a relatively high loft while also having a relatively low open area. The topsheet aids in the fluid flow through the topsheet to the secondary absorbent layer. The secondary absorbent layer absorbs the fluid and acts as a holding reservoir until the primary absorbent layer can absorb the fluid held in the secondary absorbent layer. The absorbent product has been shown to have improved rewet characteristics.
