Patent number: 7855316Abstract: An elastic laminate having an expandable facing layer, e.g., a nonwoven web with off-axis perforations, and an elastic film layer is produced to provide a preferential direction of extendability and retraction in the laminate. The elastic laminate is particularly useful as a waist area panel in disposable pant-like garments.Type: GrantFiled: December 20, 2002Date of Patent: December 21, 2010Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Stephen C. Meyer, Alvin C. Jalonen, Susan L. Bronk, Prasad Shrikrishna Potnis, Sjon-Paul Lee Conyer

Patent number: 7320948Abstract: An extensible laminate having improved set and hysteresis is disclosed. The extensible laminate includes an extensible nonwoven web laminated to an elastomeric sheet that have been mechanically stretched in the cross direction after lamination. A method for making the extensible laminate includes laminating an extensible nonwoven web to an elastomeric sheet to form a laminate and mechanically stretching the laminate in a cross direction by at least about 50 percent.Type: GrantFiled: December 20, 2002Date of Patent: January 22, 2008Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Michael Tod Morman, Sjon-Paul Lee Conyer, Gregory Todd Sudduth, Randall James Palmer, David Michael Matela, Prasad Shrikrishna Potnis

Patent number: 6821915Abstract: A breathable, substantially liquid impermeable film and laminate are provided for use in a wide variety of personal care garments and protective garments. The film, and laminate containing the film, are extendible in a cross-direction to a stretched width which is at least 25% greater than an original, unstretched width. The film and laminate have a first water vapor transmission rate of at least about 500 grams/m2-24 hours coinciding with the unstretched width. The film and laminate have a much higher second water vapor transmission rate which is at least about 225% of the first water vapor transmission rate, and not less than about 4000 grams/m2-24 hours, coinciding with a stretched width that is only 25% greater than the stretched width.Type: GrantFiled: December 28, 2000Date of Patent: November 23, 2004Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Michael Tod Morman, Patricia Hsiaoyin Hwang, Audrie Tomoko Ono, Howard Martin Welch, Charles John Morell, Faris Ohan, Prasad Shrikrishna Potnis, Michael Allen Daley, Sjon-Paul Lee Conyer

Publication number: 20040102125Abstract: An extensible laminate includes a sheet of an extensible nonwoven material that has a fabric side and a film side, a sheet of an elastomeric film, and an adhesive. The adhesive is applied to at least a portion of the film side of the extensible nonwoven material. The extensible nonwoven material is selectively attached to the elastomeric film by a plurality of intermittent adhesive bonds. The extensible nonwoven material is further selectively attached to the clastomeric film by a plurality of thermal point bonds. The intermittent adhesive bonds cover a greater percentage of an interfacial plane between the extensible nonwoven material and the elastomeric film material than the thermal point bonds. A process for making the extensible laminate is also disclosed.Type: ApplicationFiled: November 27, 2002Publication date: May 27, 2004Inventors: Michael Tod Morman, Prasad Shrikrishna Potnis, Gregory Todd Sudduth, Leslie Warren Collier, David Michael Matela, Randall James Palmer, Sjon-Paul Lee Conyer, Charles John Morell, Rasha Wafik Zaki Guirguis

Patent number: 6579274Abstract: A breathable, substantially liquid impermeable laminate is provided that is permanently conformable to the contours of a wearer's body when used in a personal care absorbent article or a medical article. The laminate includes a breathable (preferably microporous) film and a fibrous nonwoven web. Both the film and the web are extendible in a cross direction to a width at least 25% greater than an original, unstretched width upon application of a stretching force. The web and the film, and the overall laminate, exhibit little or no retractive force once they have been stretched. A diaper or other garment can be constructed in undersized fashion using the laminate, permitting material savings. When the garment is worn, the laminate stretches only where needed to provide a substantially perfect fit on the wearer. The minimal retractive force avoids the skin marks, rashes, etc. that can result from elastic garments.Type: GrantFiled: August 31, 2000Date of Patent: June 17, 2003Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Michael Tod Morman, Patricia Hsiaoyin Hwang, Audrie Tomoko Ono, Howard Martin Welch, Charles John Morell, Sjon-Paul Lee Conyer, Duane Girard Uitenbroek
