Absorbent articles
View Patent ↗The present invention provides an improved disposable article for the absorption and containment of urine or other body exudates, for example a diaper, training pants or an adult incontinence article, that has a high fecal fluid intake rate as measured by the Fecal Fluid Intake Test.
1. A disposable absorbent article for the absorption and containment of urine or other body exudates, the disposable absorbent article comprising:
a. a liquid impervious backing sheet;
b. a liquid pervious bodyside liner; and
c. an absorbent material disposed between the liquid pervious bodyside liner and the liquid impervious backing sheet,
wherein the bodyside liner comprises a woven network of fibers having an open area of 50–99% and defines a plurality of topographical features surrounded by land areas, the topographical features
being oriented towards a wearer,
projecting to a height of 2 millimeters to 10 millimeters relative to the land areas, and
defining a cross-sectional area that is 10–95% of a bodyside liner area.
2. The disposable absorbent article of claim 1 wherein the topographicel features are spaced apart by approximately ¼ inch.
3. The disposable absorbent article of claim 1 further comprising 0.08 to 0.10 cubic centimeters of air space per square centimeter surface area between a top surface of the bodyside liner and an article resting on the top surface at 0.3450 kPa load.
4. The disposable absorbent article of claim 1 wherein the bodyside liner further comprises apertures having a size of 0.25 millimeters to 5 millimeters in equivalent diameter.
5. The disposable absorbent article of claim 1 wherein at least a portion of the disposable absorbent article has a focal fluid intake rate of 1.3 to 2.8 cubic centimeters per second as measured by the Fecal Fluid Intake Test.
6. The disposable absorbent article of claim 1 wherein the woven network of the bodyside liner comprises polyester fibers.
7. The disposable absorbent article of claim 1 wherein the bodyside liner is adapted to recover to an original thickness after compressive forces are applied and removed, the compressive forces resulting in compression of 10–50% of the original thickness.
8. The disposable absorbent article of claim 1 wherein the cross-sectional area is 20–50% of the bodyside liner area.
9. The disposable absorbent article of claim 1 wherein the bodyside liner has an open area of 90–99%.
