ABSTRACT:
A method of making absorbent pads is disclosed. The method includes homogeneously mixing superabsorbent material and fluff in a forming chamber of an online drum former and wrapping a porous fabric over a forming screen on a forming drum of the drum former. The method further includes forming an absorbent pad from the homogeneously mixed superabsorbent material and fluff pulp as the homogeneously mixed superabsorbent material and fluff pulp exits the forming chamber onto the forming screen and compacting the absorbent pad to a density of at least 0.28 grams per cubic centimeter after the absorbent pad leaves the forming screen.
