A personal care product that has a liquid impermeable backsheet, a liquid permeable topsheet, and an absorbent composite located between the topsheet and backsheet. The absorbent composite has an upper layer made of synthetic fiber with at most 20 weight percent pulp and the upper layer has a density between about 0.03 and 0.15 g/cc and a basis weight between about 20 to 75 gsm. The composite has a lower layer having from 80 to 95 weight percent pulp, at most 20 weight percent binder, and has a density greater than the upper layer and between 0.06 and 0.20 g/cc, and a basis weight between 120 and 200 gsm.

Pulp and synthetic fiber absorbent composites for personal care products

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.
