Publication number: 20070149940Abstract: A multi-component nonwoven fabric can be formed with integrated liquid-acceptance and liquid-distribution layers by hydroentanglement on a three-dimensional image transfer device. Appropriate fiber selection promotes efficient fluid management, with the fabric optionally being provided with a liquid-retention layer. The invention further contemplates the formation of liquid-retention layers by hydroentanglement, with such layers exhibiting desirably high structural integrity, while providing the desired absorbent characteristics required for use in disposable absorbent products.Type: ApplicationFiled: March 2, 2007Publication date: June 28, 2007Applicant: POLYMER GROUP, INC.Inventors: Sergio Diaz De Leon, Cheryl Carlson, Nick Carter

Publication number: 20060225228Abstract: The present invention is directed to a method of forming a nonwoven fabric, which exhibits a plurality of three-dimensional images whereby the fabric is comprised of at least a first and second three-dimensional image that are dissimilar from one another. The three-dimensional images may be imparted into the fabric in a co-planar arrangement, multi-planar arrangement, or by utilizing both arrangements within the same fabric. Further, the present invention contemplates a fabric comprised of a plurality of three-dimensional images which can provide the fabric with various physical and/or aesthetic performances.Type: ApplicationFiled: June 8, 2006Publication date: October 12, 2006Inventors: Jerry Snider, Andrew Delaney, Nick Carter, Cheryl Carlson, Julie Thompson, Jennifer Mayhorn

Publication number: 20060182928Abstract: The present invention is directed a nonwoven fabric cleaning article which is imparted with a three-dimensional image or pattern during the fabrication stage. The three-dimensional image or pattern imparted into the structure of the nonwoven fabric results in a material with a variable level of leading surface contact region as measured across the face of the fabric. The leading surface contact regions are present in the form of projections out of the planar background of the fabric, the prevalence of three-dimensional projections being such that the number and/or dimension of such projections increases as one moves away from the leading edges of the cleaning article.Type: ApplicationFiled: April 17, 2006Publication date: August 17, 2006Inventors: Nick Carter, Cheryl Carlson

Patent number: 6692541Abstract: The present invention relates generally to a method of making nonwoven fabrics, wherein the fabrics are formed from splittable filaments or staple length fibers having a plurality of sub-components which are at least partially separable. The filaments or fibers are at least partially separated into their sub-components attendant to hydroentanglement, which can be effected on a three-dimensional image transfer device. Improved physical properties, including improved tensile strength, elongation, and Taber Abrasion resistance are achieved.Type: GrantFiled: May 16, 2001Date of Patent: February 17, 2004Assignee: Polymer Group, Inc.Inventors: Cheryl Carlson, John Elves, Kyra Dorsey, Ralph A. Moody, III, Valeria Erdos

Patent number: 6686196Abstract: This invention provides modified recombinant Ad vectors (e.g., AdE1− vectors) undergoing defined homologous recombination in order to create predictably rearranged genomic derivatives in a host cell. Genomic rearrangements can be achieved, for example, by incorporating two IR sequences within one vector genome and enabling genomic rearrangement by coinfection with two parental vectors of one type (also referred to herein as a one vector system) or by homologous recombination of overlapping regions in two distinct types of parental vectors (with or without IR sequences) and enabling genomic rearrangement only upon coinfection of the host cell with the two distinct parental vectors (also referred to herein as two vector system).Type: GrantFiled: May 3, 2001Date of Patent: February 3, 2004Assignee: University of WashingtonInventors: AndrĂ© Lieber, Dirk S.

Publication number: 20030087575Abstract: The present invention relates to a method of creating a textured nonwoven fabric for apparel and home fashions applications, wherein the nonwoven fabric becomes aesthetically altered upon laundering. Once laundered during manufacture, the nonwoven fabric exhibits a permanent distressed appearance that becomes an integral part of the fabric. Subsequent to laundering, the fabric can be formed into a roll for shipment and storage. The distressed appearance of the nonwoven fabric is best described by comparing the laundered fabric to an elephant's skin.Type: ApplicationFiled: November 7, 2001Publication date: May 8, 2003Inventors: Cheryl Carlson, Wayne Rhodes, Jim Lenox
