Publication number: 20010051796Abstract: A dispersible absorbent product comprises a mechanically weakened fibrous web. The dispersible absorbent product can absorb a sufficient amount of fluid without becoming overloaded and suffering from leakage, and is dispersible using a standard toilet. The mechanically weakened regions of the web enhance the dispersibility of the product. Additionally, the dispersible absorbent products may be pre-moistened with a composition. The pre-moistened products are stable in storage, easily dispersible down a toilet, and deliver cleaning, conditioning, and like benefits. Methods of making such dispersible absorbent products are also disclosed.Type: ApplicationFiled: April 20, 2001Publication date: December 13, 2001Inventors: Isao Noda, Sarah Beth Gross, Hugh Joseph O'Donnell, James Cameron Horney, Mark Dawson Midkiff
