Patent number: 7012033Abstract: Wash-durable fluorochemical-containing textile and/or fiber treatments that simultaneously impart soil resistance (or soil-release) properties and moisture wicking characteristics to target fabric substrates are provided. Such treatments surprisingly impart these two simultaneous effects to target fabrics and/or fibers because fluorochemicals generally provide moisture repellency rather than moisture wicking capabilities. As prior soil release/moisture wicking treatments do not function properly, or, alternatively, compromise hand or other properties of certain target textiles after treatment application, a new, effective, soil release/moisture wicking formulation for such purposes was needed. The inventive treatment is extremely durable on such fabric substrates; after a substantial number of standard launderings and dryings, the treatment does not wear away in any appreciable amount and thus the substrate retains its soil release/moisture wicking properties.Type: GrantFiled: January 24, 2003Date of Patent: March 14, 2006Assignee: Milliken and CompanyInventors: Heather J.

Patent number: 6964803Abstract: Absorbent structures having controlled liquid intake, distribution and absorption properties include at least one substrate layer and a flexible absorbent binder formed on and bound to the substrate at selected locations. The flexible absorbent binder is selectively formed so as to provide flow channels, regions of higher and lower fluid intake and absorption, dams for preventing fluid leakage, and other desirable features. The absorbent structures are useful in personal care absorbent articles such as sanitary napkins, diapers, training pants, adult incontinence garments and the like.Type: GrantFiled: May 1, 2003Date of Patent: November 15, 2005Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Candace Dyan Krautkramer, Russell Paul George, Kenneth Russell Casson, Dave Allen Soerens, Jason Matthew Laumer, James Hongxue Wang

Patent number: 6939492Abstract: Disclosed herein is a method for making fibrous web materials which may be used in or as absorbent core materials for absorbent products. The method involves providing loose fibers, entraining the fibers in a moving airstream, treating the fibers with an energy-activatable pre-polymer composition and subjecting the fibers to activation energy to initiate cross-linking of the composition. The fibers are collected on forming surface to form a fibrous web. The fibers may be treated with the composition while entrained in the moving air or after being collected on the forming surface, or in an alternate embodiment by treating with the composition a mat of fibers from which the loose fibers are provided. The fibrous web material may comprise cellulosic fibers such as pulp, and/or synthetic fibers such as staple fibers, and/or super absorbent materials.Type: GrantFiled: December 26, 2002Date of Patent: September 6, 2005Assignee: Kimberly-Clark Worldwide, Inc.Inventors: David Martin Jackson, Jason Sybren Fairbanks, John Gavin MacDonald

Patent number: 6905986Abstract: The present invention is directed to an absorbent composite containing superabsorbent material. The superabsorbent material is in the form of superabsorbent particles having a bimodal particle size distribution. Use of superabsorbent material having a bimodal particle size distribution in the absorbent structure results in enhanced fluid distribution and fluid intake of the absorbent composite. The absorbent composite of the present invention is useful in disposable personal care products.Type: GrantFiled: October 9, 2001Date of Patent: June 14, 2005Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Sridhar Ranganathan, Richard Norris Dodge, II, Michael John Niemeyer

Patent number: 6846518Abstract: This invention discloses a continuous production method of water-absorbing composite which comprises a complexation step for producing a particle-substrate composite by dropwisely supplying an aqueous solution of polymerizable monomers consisting mainly of an unsaturated carboxylic acid where 20% or more of the carboxyl groups in the unsaturated acid is neutralized, while allowing polymerization to proceed in the droplets, onto a fibrous substrate fed to the drop point to allow the incompletely polymerized polymer particles to adhere thereon, and by completing the polymerization thereafter; and a surface crosslinking step for reacting the composite with a crosslinking agent, having two or more functional groups capable of reacting with carboxyl group and/or carboxylate group, in the presence of 1 to 100 weight parts of water per 100 weight parts of polymer particles derived from the polymerizable monomer contained in the composite.Type: GrantFiled: September 17, 2001Date of Patent: January 25, 2005Assignee: Mitsubishi Chemical CorporationInventors: Kouji Katoh, Kiichi Itoh, Yoshiaki Mori
