Abstract
Absorbent articles are disclosed that, in one embodiment, can comprise feminine hygiene products. The absorbent articles can include a multi-layer absorbent substrate. The absorbent substrate contains a retention layer comprised of superabsorbent material. The absorbent substrate can also include a top intake layer comprised primarily of polymer synthetic fibers and binder fibers. The top intake layer is to provide strength and integrity. The absorbent substrate is made according to a wetlaid process, such as a foam forming process. Prior to drying the absorbent substrate or bonding the absorbent substrate, a surfactant composition is applied that has been found to dramatically improve fluid intake rates.
