The absorbency of a disposable diaper is increased by spraying the diaper with an aerosol spray containing absorbent powder, e.g. talcum, cornstarch or both. The powder particles are so fine (20-40 micron diameter) that the spray force drives many of them into the subsurface layers of the diaper, thus increasing the absorbency of the diaper. At the same time, some powder remains on the diaper surface to help protect the skin of the wearer in the absence of urine.
