ABSTRACT:
The present invention is directed to an improved disposable diaper and method therefor. The disposable diaper achieves significant fluid absorbency through a wadding batt layer consisting solely of a combination of wood pulp and cotton pulp, rather than through a wadding batt layer comprising wood pulp and a superabsorbent polymer. In this fashion, the disposable diaper minimizes skin irritation that may be caused during rewetting when body waste fluids contacting the superabsorbent polymers carry a portion thereof back out through the diapers into contact with the skins of babies or children using the diapers. The disposable diaper also minimizes skin irritation caused when both the exterior portion of a diaper contacts a child's skin or the skin of a person touching the diaper, by the use of an outer and inner surface layer of a soft, cloth-like, non-woven bond material such as polyester.
