Disposable Articles Using High Column AUL Superabsorbents
Patent #: 7,838,721
Inventor(s): Dennis Chen
Company: Paragon Trade Brands, LLC
Patented recently is an invention which relates to an absorbent composite for an absorbent article, and more particularly to an absorbent composite comprising fibrous material and superabsorbent material having a Column Absorbency Under Load (CAUL) above 10 g/g. Such an absorbent composite provides a superabsorbent material having superior AUL and permeability, thereby providing improved absorption and rewetting properties. An absorbent article that contains such a composite provides improved ability to absorb and retain fluids, thus preventing excessive rewetting and leakage and making the article more comfortable to wear. An absorbent garment includes an extensible backsheet having opposite side regions, a liquid permeable topsheet having opposite side portions, and a retention portion having opposite side edges and an inner surface defining an area. The retention portion is disposed between the topsheet and the backsheet with the inner surface facing the topsheet and with the opposite side portions of the backsheet and the topsheet extending beyond the side edges of the retention portion. The opposite side portions of the topsheet are attached to the opposite side portions of the backsheet on opposite sides of the retention portion. Less than 30% of the area of the inner surface of the retention portion is attached to the topsheet. A method for absorbing bodily exudates with an absorbent garment is also provided.
