Abstract

The invention is generally accomplished by providing a disposable garment comprising a liquid impervious backing sheet, a liquid pervious body-side liner sheet, and an integral absorbent pad disposed between the liner and cover sheets. The absorbent pad is provided with a high absorbency area extending from the crotch region toward the center of the front waist of the garment. It is preferred that about 65 percent of the total absorbent be in the front half of the diaper with the about 40 percent of the total in the high absorbency area.

9. The garment of claim 1 wherein said absorbent is wood fluff between about 0.5 and about 0.8 inch thick in said center front panel and between about 0.2 and about 0.5 inch thick in the remainder of said garment with a height difference between the fluff in the ears of said garment and said center front panel of between about 0.3 and about 0.6 inch.

10. The garment of claim 1 wherein the absorbent area of said front center panel has a length of between about 9 and about 5.5 inches and a width of between about 4 and about 5 inches.
