Abstract
A technique to preserve absorbent core integrity in a disposable article is described.
Columns which protrude from the backing sheet of an absorbent disposable article or personal wear garment and which project into the fibrous mass of an absorbent core overlaid onto a liquid impervious backing sheet are disclosed. A top sheet which is pervious to liquids overlies the core of fibrous material encapsulating the absorbent core in cooperation with the backing sheet. The top sheet also may carry similar columns. These columns act to restrict the movement of the fibers in the absorbent core and, more particularly, to enhance and maintain the integrity of the absorbent core whenever wet and/or placed under stress. These columns serve to resist and to diminish any disintegration of the absorbent core.
