Abstract
A method of incorporating a density modulator into an absorbent composite includes the steps of applying a density modulator solution to a pulp sheet, fiberizing the pulp sheet, and incorporating the fiberized pulp sheet into an absorbent composite. The density modulator can be applied by slot coating or by using a flooded nip. Once the density modulator is incorporated into the absorbent composite, the absorbent composite is highly wettable and, upon contact with blood-containing bodily fluids, undergoes a decrease in density, thereby increasing the absorbent capacity of the absorbent composite.
