Patent number: 7081560Abstract: The present invention relates to absorbent articles having a topsheet, a backsheet, and an absorbent core between the topsheet and the backsheet. The backsheet comprises a moisture vapor permeable, substantially liquid impermeable composite sheet material includes a powder-bonded nonwoven web adhered to a moisture vapor permeable thermoplastic film. The nonwoven web includes a first layer comprised primarily of fibers that are compatible with an adhesive used to bond the web, and a second layer comprised of a blend of fibers, some of which are compatible with, and some of which are incompatible with the bonding adhesive and the thermoplastic film. A method for making the composite sheet material and an item of apparel made from the sheet material are also provided.Type: GrantFiled: June 2, 2000Date of Patent: July 25, 2006Assignee: The Procter & Gamble CompanyInventors: Hyun Sung Lim, George Joseph Ostapchenko

Patent number: 5938648Abstract: The present invention relates to absorbent articles such as diapers, adult incontinence garments, and feminine hygiene products. The present invention further relates to such absorbent articles having outer coverings designed to provide breathability and promote more healthy internal environmental conditions for the wearer. More specifically, the present invention provides an absorbent article comprising (a) a topsheet; (b) a backsheet; and (c) an absorbent core located between the topsheet and the backsheet; wherein the backsheet comprises a non-porous, substantially fluid impermeable, moisture vapor permeable composite sheet material. Preferably, the composite sheet material is oriented such that the film layer of the composite sheet material faces toward said absorbent core. Where the film layer of the composite sheet comprises a substantially hydrophilic elastomer film layer, the substantially hydrophilic elastomer film is preferably located in contact with the fibrous substrate.Type: GrantFiled: December 3, 1997Date of Patent: August 17, 1999Assignee: The Procter & Gamble Co.Inventors: Gary Dean LaVon, Hyun Sung Lim, J.
