Abstract
An absorbent core structure is disclosed for acquiring and absorbing aqueous-based liquids in hygiene products. The core structure includes a nonwoven blend of fluff pulp for wicking and absorbing an aqueous-based liquid, a superabsorbent polymer for absorbing an aqueous-based liquid and retaining the liquid against moderate pressure against the core structure, a binding element or structure (such as a synthetic bicomponent filament) for providing at least some of the bonding in the nonwoven blend, and a plurality of small denier hollow filaments for enhancing the moisture transport and storage of the liquid and improving the physical structure as compared to fluff.
