Patent number: 9561139Abstract: A method of making an absorbent composite that includes a first fabric, a second fabric, and particles positioned between the two fabrics and absorbent articles made from the absorbent composite. The particles are secured between the two fabric using adhesive, thermal plastic or combinations thereof. The fabrics are bonded together in a manner that limits particle movement between the fabrics. The bond pattern may define pockets or other shapes. In applications in which the bond pattern forms pockets, the particles may be positioned in the pockets. The particles may be SAP particles or other particles with advantageous properties.Type: GrantFiled: March 19, 2012Date of Patent: February 7, 2017Assignee: DSG Technology Holdings Ltd.Inventors: Patrick Tsang, Kuo-Shu Edward Chang, Andrew Wright

Patent number: 8333749Abstract: A disposable absorbent article with a central body and a pair of elasticized side panels that extend longitudinally along the sides of the central body. Each side panel has a front longitudinal edge and a rear longitudinal edge opposite the front longitudinal edge, and a front or rear fastening element positioned adjacent the front or rear edge. The front edge of the side panel is positioned closer to the front waist portion than the rear edge. The fastening element is constructed for fastening the front and rear waist portions of the central body when the disposable absorbent article is worn by a user. Further, each side panel includes elastic elements that are positioned along the length of the side panel such that the side panel has generally greater elasticity in the vicinity of the rear edge than in the vicinity of the front edge.Type: GrantFiled: May 20, 2003Date of Patent: December 18, 2012Assignee: DSG Technology Holdings Ltd.Inventors: Patrick Tsang, Anne Smid, Andrew Wright

Publication number: 20080093015Abstract: A method of making an elastic composite is provided. The method entails conveying a first web of material along a web plane path. The method also entails applying a first section of a first elastic strand onto the first web and generally transversely to the web plane path and applying a second section of a second elastic strand onto the first web and generally transversely to the web plane path. These applying steps are repeated while performing the conveying step, thereby arranging a plurality of first and second elastic elements on the first web, in generally parallel relation to one another. The resultant composite is suitable for incorporation into a disposable absorbent garment, textile or fabric structure, and the like.Type: ApplicationFiled: May 9, 2007Publication date: April 24, 2008Applicant: DSG Technology Holdings Ltd.Inventors: Kuo-Shu Chang, Chang-Hwa Grace, Anne Smid, Patrick Tsang, Andrew Wright, William Sayers

Publication number: 20070016155Abstract: A disposable absorbent article defining an absorbent chassis adapted to wrap around portions of a torso and a pair of side panels adapted to secure the absorbent chassis about the torso during use. The side panels include at least a pair of substantially inextensible zones and a zone of substantial elasticity providing partial extensiblity to the side panels. The side panels may be secured to the chassis at one of the inextensible zones and be provided with a fastener component at another inextensible zone. At least portions of opposed edges of the side panels are shaped into a nonparallel configuration to improve fit, comfort and exudate control of the absorbent article.Type: ApplicationFiled: June 26, 2006Publication date: January 18, 2007Inventors: Kuo-Shu Chang, Andrew Wright, Patrick Tsang, Steven Linton

Publication number: 20060241560Abstract: A pant-like, refastenable, disposable absorbent article which defines a front waist region, a back waist region and a pair of opposed side panels which extend outwardly from the side edges of the absorbent chassis in the front or back waist region. Each side panel includes at least one elastic zone providing panel extensibility and at least a pair of inextensible zones adjacent an elastic zone. Fastener components of the side panels are used to connect the front waist region to the rear waist region to define the pant-like article. The side panels may also be defined by a pair of side panel margins which extend outwardly from the side edges of the absorbent chassis in both the front waist region and the back waist region and which are joined at the user's side.Type: ApplicationFiled: April 22, 2005Publication date: October 26, 2006Inventors: Kuo-Shu Chang, Patrick Tsang, Andrew Wright

Publication number: 20060167424Abstract: A disposable absorbent article comprising a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core interposed between the topsheet and the backsheet. The absorbent member is defined by a pulp-less absorbent core having a superabsorbent material providing efficient fluid handling characteristics. The absorbent core may be defined by its fluid handling properties including, but not limited to, greater absorbency rate index (ARI) and greater percentage absorbency rate index (PARI) as compared to absorbent articles of conventional pulp-containing technology.Type: ApplicationFiled: December 30, 2005Publication date: July 27, 2006Inventors: Edward Chang, Patrick Tsang, Andrew Wright

Publication number: 20050131373Abstract: An elastic composite is provided in a disposable absorbent garment such as a diaper or training pants. The elastic composite has a base layer, a top layer, and an elastic construction disposed therebetween. The elastic construction includes a plurality of spaced apart (e.g. generally equally spaced apart) elastic elements (e.g. strands or threads) that are aligned in a generally cross machine direction and in generally parallel relation. Further, the top and base layers define a first longitudinally extending side edge and a second longitudinally extending side edge between which, the elastic construction is disposed. The elastic composite further includes an elasticized region, wherein the elastic construction is disposed, a first non-elasticized region disposed between the first side edge and the elasticized region, and a second non-elasticized region disposed between the second side edge and the elasticized region.Type: ApplicationFiled: December 11, 2003Publication date: June 16, 2005Inventors: Andrew Wright, Kuo-Shu Chang, Patrick Tsang, Anne Smid

Publication number: 20040236299Abstract: A disposable absorbent article is provided in a generally flat, open condition. The disposable absorbent article has a central body that includes an absorbent core, a front longitudinal edge, and a rear longitudinal edge opposite the front longitudinal edge. The front and rear edges partially define front and rear waist portions, respectively, of the central body. The central body is further characterized by a longitudinal centerline extending across the front and rear edges. The disposable absorbent article also has a pair of elasticized side panels that extend longitudinally adjacent opposite lateral sides of the central body. Each side panel has a front longitudinal edge and a rear longitudinal edge opposite the front longitudinal edge, and a front or rear fastening element positioned adjacent the front or rear edge.
