METHOD FOR PRODUCING A SUBSTRATE， and SUBSTRATE.

A method for producing a high-bulk， foam-formed substrate includes producing an aqueous-based foam including at least 1% by weight crimped synthetic fibers and at least 1% by weight binder fibers; forming a wet sheet from the aqueous-based foam; and drying the wet sheet to obtain the foam-formed substrate. A substrate includes an aqueous-based polymer foam including at least 1% by weight crimped synthetic fiber and at least 1% by weight binder fiber， wherein the substrate is free of superabsorbent material. A method for producing a high-bulk， foam-formed substrate includes producing an aqueous-based foam including at least 2% by weight crimped binder fibers; forming a wet sheet from the aqueous-based foam; and drying the wet sheet to obtain the foam-formed substrate， wherein the foam-formed substrate is free of superabsorbent material， and wherein the substrate has a dry density between 0.02 g/cc and 0.1 g/cc.
