Patent number: 7465373Abstract: An unitary stratified composite composed of a first stratum and a second stratum integrally connected by a transition zone is disclosed. The first stratum serves as a liquid acquisition stratum that rapidly acquires and then transfers liquid to the second stratum. The second stratum serves to withdraw liquid from the first stratum and further severs as a temporary storage stratum. Methods for forming the unitary stratified composite are also disclosed.Type: GrantFiled: May 4, 2006Date of Patent: December 16, 2008Assignee: National Institute for Strategic Technology Acquisition and CommercializationInventors: Peter A.

Patent number: 7166190Abstract: Methods for forming an absorbent fibrous composite containing absorbent material dispersed in bands through the composite and along the composite's length are disclosed. The methods generally include depositing a fibrous slurry on a foraminous support to form a web and depositing or injecting absorbent material into the web across its width to provide a web having absorbent material in bands along the composite's length. Drying the web provides a fluted absorbent composite. In one embodiment, the method is a wetlaid method and in another embodiment, the method is a foam-forming method. Preferably, the methods are twin-wire forming methods.Type: GrantFiled: February 28, 2005Date of Patent: January 23, 2007Assignee: National Institute for Strategic Technology Acquisistion and CommercializationInventors: Peter A.

Publication number: 20030139718Abstract: An absorbent composite having a reticulated core and a fibrous stratum is disclosed. The core and stratum are integrally formed, and the stratum is coextensive with a surface of the core. In one embodiment, the composite includes strata on opposing surfaces of the core. The core includes a fibrous matrix and absorbent material. The fibrous matrix defines voids and passages between the voids, which are distributed throughout the composite. Absorbent material is located within some of the voids. On wetting, absorbent material located in these voids is expandable into the void. Methods for forming the composite and absorbent articles that include the composite are also disclosed.Type: ApplicationFiled: November 13, 2002Publication date: July 24, 2003Applicant: Weyerhaeuser CompanyInventors: Peter A.
