Patent number: 7291239Abstract: High loft, low density nonwoven webs are produced by forming substantially continuous, spunbond, crimped, bicomponent fibers of A/B bilateral morphology in an unheated fiber draw unit. The fibers are then heated and cooled in the absence of impeding forces to achieve maximum crimp in the z-direction and produce a web of lofted material. The resultant material is particularly suitable for use as an insulator. Particulates may be added to the webs if desired.Type: GrantFiled: September 10, 2004Date of Patent: November 6, 2007Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Braulio A. Polanco, Christopher Dale Fenwick, Darryl Franklin Clark, Bryan David Haynes, Kurtis Lee Brown, Chad Michael Freese

Patent number: 7258758Abstract: High loft, low density nonwoven webs suitable for use in a variety of applications requiring strong fabric layers are produced by forming substantially continuous, spunbond, crimped, bicomponent fibers of crimpable, e.g., side by side or eccentric sheath/core (A/B) configuration which are unheated prior to collection. The fibers are then heated and cooled in the absence of impeding forces to achieve maximum crimp in the Z-direction and produce a web of lofted material of greater uniformity than attained with comparable material whose fibers are drawn by a heated process. The resultant nonwoven material can then be pattern bonded or laminated for additional strength without interfering with the desired loft of the low density nonwoven. The additionally strengthened nonwoven may then be further processed such as by lamination or the like to further increase its utility.Type: GrantFiled: December 31, 2003Date of Patent: August 21, 2007Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Warren L. Collier, IV, Christopher Dale Fenwick, Chad Michael Freese, Kurtis Lee Brown, Susan Elaine Shawver, Terry Kramer Timmons, James Russell Fitts, Jr., Monica Graciela Varriale, Alexander J.

Patent number: 7189888Abstract: This invention is a surge material having permanent storage properties that results in faster intake and greater saturation capacity and reduced fluid flowback. More specifically the invention is a surge material with a superabsorbent material printed on in a pattern of discrete regions. The objective of the invention is obtained by printing, or other known application process, a liquid superabsorbent precursor solution containing a crosslinkable composition onto a surge material and then curing the printed surge material to crosslink the polymers to get a surge material having discrete regions of superabsorbent material in the surge material. This invention is also useful in making an absorbent core of an absorbent article with improved strength, increased absorbency, and decreased shedding of superabsorbent material.Type: GrantFiled: December 21, 2001Date of Patent: March 13, 2007Assignee: Kimberly-Clark Worldwide, Inc.Inventors: James Hongxue Wang, Jian Qin, Jayant Chakravarty, Fu-Jya Daniel Tsai, Roland Columbus Smith, Jr., Christopher Dale Fenwick, Palani Raj Ramaswami Wallajapet, D.

Patent number: 6874505Abstract: A surgical drape system is provided including a drape component and a pouch component. The drape component has a main sheet portion and may have a fenestration for providing access to an operative site on a patient. The pouch component may be created from a rear panel and a front panel superimposed and partially sealed one to the other to provide a pouch having an open top and partially open sides. The rear panel is attached to the drape in proximity to the fenestration and holds the pouch in place on the drape. A number of spaced apart fasteners are disposed upon at least one of the panels proximate to the open top. The fasteners are for fastening sections of the front and rear panel to one another thus establishing alternating fastened and unfastened regions in the open top.Type: GrantFiled: September 19, 2003Date of Patent: April 5, 2005Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Christopher Dale Fenwick, Casey Lynn Dusenbery

Patent number: 6663611Abstract: An absorbent article including a liquid-permeable top layer, an absorbent core layer, and a breathable outer cover is provided with a breathable inner laminate between the absorbent core and the outer cover. The breathable inner laminate includes a breathable film and a nonwoven filament web, and is less breathable than the outer cover. The low to moderately breathable inner laminate substantially reduces perceived dampness occurring on the external surface of the highly breathable outer cover, following a liquid insult, when the article is being worn, without seriously hampering moisture flux out of the diaper. Direct pathways for moisture near the wearer's skin to exit the article are maintained, and a concentration gradient is enhanced.Type: GrantFiled: September 28, 1999Date of Patent: December 16, 2003Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Carol Ann Blaney, Ann Louise McCormack, Christopher Dale Fenwick, Tamara Lee Mace
