Patent number: 7118639Abstract: A method for producing an apertured structured material for accommodating passage of fluids, particularly high viscosity fluids, through the apertured structured material. In one embodiment, the apertured structured material is a composite material formed by differential shrinkage of a shrinkable second layer, for example an ethylene-propylene copolymer, which is laminated to a first layer, for example a polypropylene polymer. During the differential shrinkage process, a plurality of slits which are formed in the second layer open to form uniformly-shaped apertures. In another embodiment, an apertured structured heterogenous material is made of a heterogeneous mixture of at least two homogeneous fiber sets or components having different shrinkage extents.Type: GrantFiled: May 31, 2001Date of Patent: October 10, 2006Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Mary Lucille DeLucia, Sandy Chi-Ching Tan, Eugenio Go Varona, Jessica B.

Patent number: 6838154Abstract: There is provided a resilient, three dimensional material having fibrous texture and appearance and capable of fluid handling. It consists of a top surface and a bottom surface wherein fiber-like elements typically extend from one surface to the other forming flat to undulating surfaces characterized by a multiplicity of interconnected fluid passageways. Deformed, discontinuous film-like or encapsulated regions connect fiber-like elements and stabilize the material. The material of this invention is unique based on the three principle characteristics which are communicated in this application: 1) ff(?)<0.87, 2) SA/VV<186 cm2/cm3, and 3) caliper<0.150 inches. This material is useful for a number of purposes, such as for use as a liner for personal care products like diapers, absorbent underpants, swim wear, feminine hygiene products, adult incontinence products and the like.Type: GrantFiled: December 9, 1998Date of Patent: January 4, 2005Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Eugenio Go Varona, Monica Lynn Bontrager, Jaime Braverman, Kuo-Shu Edward Chang, Michael Allen Daley, Karen Lynn English, Arthur Edward Garavaglia, Hristo Angelov Hristov, Nancy Donaldson Kollin, Tamara Lee Mace, David Michael Matela, Sharon Rymer, Reginald Smith, Roland Columbus Smith, Jr., Michael Donald Sperl

Patent number: 6797360Abstract: There is provided a new nonwoven material for personal care products made of fibers, binder in an amount between 1 and 6 weight percent and superabsorbent in an amount between 1 and 80 weight percent, where the superabsorbent is contained in micro-pockets in the nonwoven. These micro-pockets may be made by creping a nonwoven fabric, orienting fibers in the Z-direction, and by passing a relatively lofty nonwoven fabric between unheated thermal pattern bond and anvil rolls. These materials exhibit good permeability to liquid in the pre- and post-wetted conditions, thus avoiding gel blocking and other negative effects of superabsorbent swelling within a fabric. Such a fibrous material is useful in personal care products, like diapers, training pants, incontinence garments and feminine hygiene products.Type: GrantFiled: August 22, 2001Date of Patent: September 28, 2004Assignee: Kimberly-Clark Worldwide, Inc.Inventor: Eugenio Go Varona

Patent number: 6673980Abstract: An absorbent article including a liquid-permeable top layer, an absorbent core layer, a breathable outer cover, and a creped inner nonwoven fibrous layer between the absorbent core and breathable outer cover. The creped inner nonwoven fibrous layer has a level of creping of about 5-75%, and is preferably permanently creped. The creped inner nonwoven fibrous layer serves as a dampness inhibitor which reduces or prevents perceived dampness on the external surface of the outer cover by lowering thermal conductivity between the absorbent core and the outer cover surface.Type: GrantFiled: July 16, 1999Date of Patent: January 6, 2004Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Eugenio Go Varona, Carol Ann Blaney, Audrie Tomoko Ono, Tamara Lee Mace
