Patent number: 8021996Abstract: The present invention provides a nonwoven web prepared from multicomponent fibers which are partially split. The partially split multicomponent fibers have at least one component of the multicomponent fiber separated from the remaining components of the multicomponent fiber along a first section of the longitudinal length of the multicomponent fibers. Along a second section of the longitudinal length of the multicomponent fibers the components of the multicomponent fibers remain together as a unitary fiber structure. In addition, part of the second section of the multicomponent fibers is bonded to part of a second section of an adjacent multicomponent fiber.Type: GrantFiled: December 23, 2008Date of Patent: September 20, 2011Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Susan Kathleen Walser, Leon Eugene Chambers, Jr., Reginald Smith, Nancy J.

Patent number: 6890622Abstract: An in-line formed, non-laminated web is suitable for use as a composite fluid distribution and fluid retention layer in a disposable absorbent article. The web can be formed by selective deposition of airlaid materials including absorbents, such as pulp and superabsorbents, together with binder fibers. The web so constructed will have a plurality of intermingled lower basis weight areas and higher basis weight areas coexisting and distributed in at least a central region of the web, the alternations crossing the X axis or Y axis, or both, of the web, with the higher basis weight areas being a greater thickness in the Z-direction than the lower basis weight areas. The web so constructed will further have no discrete material boundaries between the lower basis weight stripes and the higher basis weight stripes. Further the necessity of later processing on the web to achieve a ridged structure is removed and the fibers will remain whole and undisturbed.Type: GrantFiled: December 20, 2001Date of Patent: May 10, 2005Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Gabriel Hamman Adam, Leon Eugene Chambers, Jr., John Herbert Conrad, Robert G. Geer, Eric Edward Lennon, Sridhar Ranganathan

Patent number: 6709613Abstract: A nonwoven web contains an even distribution of its composite materials by the separate application of particulate material such as superabsorbent particles into a forming head outside the air stream for deposition of thermoplastic fibers in the forming head. The thermoplastic fibers are distributed by air entertainment through tubular forming screens having rotary distribution members therein. The particulate absorbents are generally placed in the forming box by distribution units which may have metering devices and outlet chutes extending into the forming head.Type: GrantFiled: December 21, 2001Date of Patent: March 23, 2004Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Leon Eugene Chambers, Jr., Eric Edward Lennon, Gabriel Hamman Adam, Jerome Joseph Schwalen, Christopher Andrew Laslie, H.

Publication number: 20030118764Abstract: An in-line formed web having major surfaces in the X-Y plane and a depth in the Z direction is suitable for use as a composite fluid distribution and fluid retention layer in a disposable absorbent article. The web contains multiple layers of composite material which may have both thermoplastic fibers and absorbent material. The multiple layers can have different compositions of thermoplastic fibers and absorbent material as applied in-line by various arrangements of thermoplastic melt dies and absorbent fiber dispensers. By arranging at least two of the multiple layers in an opposing relation overlaid in the Z-axis direction of the web, a gradient can be formed in the Z-direction of the web. By coordinating the timing and deposition of the material onto a forming wire, at least one of the multiple layers is arranged to have zones of intermittent material deposition in at least one of a machine direction or a cross direction of the web.Type: ApplicationFiled: December 20, 2001Publication date: June 26, 2003Inventors: Ricky Alton Adams, Leon Eugene Chambers, Robert G. Geer, Lamar Heath Gipson, Eric Edward Lennon, Lewis Thomas Nicholson, Sridhar Ranganathan, James R. Sanders, Jerome Joseph Schwalen, Richard Norris Dodge, Lawrence Howell Sawyer

Patent number: 6470943Abstract: Methods and systems for making an absorbent pad for use in an absorbent article utilize a forming device for forming material into an absorbent core, a supply device for supplying a containment layer against the first surface of the absorbent core and spray apparatus for spraying fibers of molten resin onto the second surface of the absorbent core. The fibers form a stabilization layer on the absorbent core that increases the integrity of the absorbent core. The spray apparatus includes a nozzle having a resin aperture for exhausting resin therefrom and multiple gas apertures for exhausting gas therefrom to provide a random pattern to the fibers of molten resin as the fibers are sprayed onto the second surface. Resin can also be sprayed onto first and second portions of the containment layer extending outwardly from edges of the absorbent core so the containment layer and the stabilization layer encompass the absorbent core.Type: GrantFiled: April 13, 2001Date of Patent: October 29, 2002Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Kenneth Thomas Borowski, Joseph Michael Kugler, James George Van Himbergen, Norman Earl Brown, Leon Eugene Chambers, Jr., John Christopher Garstka, David Charles Musil, Edward Erich Werner
