EMULSION-CONTAINING ABSORBENT ARTICLE HAVING IMPROVED WATER HOLDING CAPACITY ABSTRACT OF THE DISCLOSURE A water-in-oil emulsion at a ratio of 80/20 or less when incorporated into a water absorbing material (such as a polyurethane sponge) will aid in retaining water that may be subsequently added to the absorbing material. The effect is believed due to the in- creased viscosity of the emulsion when water is added. The effect is particularly useful for improving urine retention of diapers, such as disposable diapers or similar articles.
