Patent number: 11220085Abstract: An elastic laminate is provided including at least one gathered outer facing layer of a fabric and an apertured elastic film attached thereto. The aperture film includes a series of alternating first and second segments that extend continuously along the direction of elasticity. The first segments of the film are substantially devoid of any apertures and the second segments are strewn with apertures of irregular size and shape. The regionally limited and irregular apertures are formed by the controlled rupturing of the film within those segments. The elastic laminate has excellent air-permeability and elastic properties.Type: GrantFiled: February 28, 2018Date of Patent: January 11, 2022Assignee: KIMBERLY-CLARK WORLDWIDE, INC.Inventors: Jose Augusto Vidal De Siqueira, Michael R.

Publication number: 20210086487Abstract: A method of making a composite elastic laminate is provided where an elastic layer is stretched in the machine-direction and while in a stretched state is fed into a grooved-roll assembly, together with outer facing layers, for imparting simultaneous cross-direction stretching forces to the superposed layers. The bi-directional stretching forces causes the elastic layer to tear and/or rupture allowing the laminate to be bonded in areas where the elastic layer has been displaced. Upon relaxation, a composite elastic laminate is provided having excellent breathability and elastic properties.Type: ApplicationFiled: August 30, 2018Publication date: March 25, 2021Inventors: Jose Augusto Vidal De Siqueira, Michael R. Vaughan

Publication number: 20210069028Abstract: An elastic laminate is provided including outer facing layers of a fabric and, located between the outer facing layers, a series of individual, spaced apart strips of elastic film extending continuously along the direction of elasticity. The film strips are formed by a controlled tearing of a continuous film while the film is biaxially stretched and bonded to the fabric facings. The fabric facings have gathers formed therein that allow the elastic laminate to stretch at least to the extent that the gathers can be pulled flat.Type: ApplicationFiled: February 28, 2018Publication date: March 11, 2021Inventors: Jose Augusto Vidal De Siqueira, Michael R.

Patent number: 10081123Abstract: Unitary films and laminates thereof are provided having at least first and second film segments which extend adjacent one another and are permanently joined together. The first and second film segments are joined at an interface, wherein at the interface a tip of the second segment overlaps the first segment in the cross-direction of the film. The film has a thickness “T” at the tip of the second segment, and the second segment has a thickness “t” at a distance T in the cross direction from the tip of the second segment. The ratio T/t is suitably greater than about 3. The unitary films and laminates thereof are well suited, for example, for use as outer covers in personal care articles.Type: GrantFiled: October 27, 2014Date of Patent: September 25, 2018Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Wing-Chak Ng, Jose Augusto Vidal de Siqueira

Patent number: 9676164Abstract: As described herein, an extensible sheet material includes a first and a second zone that is separate from the first zone. The first zone exposes a first color or pattern when the extensible sheet material is stretched beyond a first percentage. The second zone exposes a second color or pattern when the extensible sheet material is stretched beyond a second percentage greater than the first percentage. Absorbent articles that include the extensible sheet material are capable of indicating to a wearer when the extensible sheet material has been stretched too little, too much, or just the right amount.Type: GrantFiled: July 18, 2011Date of Patent: June 13, 2017Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Wing-Chak Ng, Jose Augusto Vidal de Siqueira, Lawrence H.

Publication number: 20120148796Abstract: An elastic nonwoven composite that contains an elastic film laminated to one or more nonwoven web materials is provided. The composite is formed by passing an extrusion-coated film/nonwoven laminate through a nip to create apertures through both the film and the nonwoven. The apertures are of a size sufficient to provide a desired level of texture, softness, hand feel, and/or aesthetic appeal to the composite without having a significant adverse effect on its elastic properties. Apertures are accomplished in the present invention by selectively controlling certain parameters of the lamination process, such as film content, element pattern, degree of film tension, temperature and pressure conditions, and so forth.Type: ApplicationFiled: December 14, 2010Publication date: June 14, 2012Inventors: Howard M. Welch, Glenda J. Rhodes, Lei Huang, Matthew B. Lake, Wing-Chak Ng, Akwokwo H. Redhead, Jose Augusto Vidal de Siqueira, Oomman P. Thomas
