  • Publication number: 20120151722
    Abstract: A method of making a structured surface and a mechanical fastener precursor are disclosed. The method includes providing a thermoplastic backing with spaced-apart, upstanding posts with base portions attached to the thermoplastic backing and distal tips; deforming the distal tips to form caps on at least some of the spaced-apart, upstanding posts to provide capped posts, wherein at least some caps upon forming touch at least one adjacent cap; and separating the capped posts. Typically, the at least some caps upon forming are shaped at least partially by the at least one adjacent cap. The mechanical fastener precursor includes a thermoplastic backing and upstanding male fastening elements with bases attached to the thermoplastic backing and distal caps larger in area than the cross-sectional area of the bases, wherein the bases of the male fastening elements are spaced apart, wherein at least some of the distal caps touch at least one adjacent distal cap.

  • Publication number: 20120070480
    Abstract: Disposable absorbent articles comprising an absorbent material and an antimicrobial composition are disclosed. The antimicrobial composition includes a carrier comprising fatty alcohol and a poly(alkyleneoxy) polymer, and an antimicrobial agent. The antimicrobial composition may be coated on to component substrates such as nonwovens and films, that are incorporated into disposable absorbent articles, such as disposable infant diapers, adult incontinence articles, feminine hygiene articles such as sanitary napkins, wound dressings, bandages, panty liners and tampons, personal care wipes and household wipes to provide odor control, and control of microbial growth.

  • Publication number: 20110313389
    Abstract: A hook strip is provided having a backing with a first surface and a length in a first direction; multiple rows of hook elements aligned in the first direction and projecting from the first surface of the backing; and slits in the backing between at least some pairs of adjacent rows of the hook elements. The slits may be interrupted by a bridging region of the backing, or the slits may be partial slits that penetrate the thickness of the backing in a range from 40 to 90 percent. A fastening laminate that includes a carrier and the hook strip described above joined to the carrier is also provided. In some embodiments, the fastening laminate includes slits that form separate, abutting portions of the backing on the carrier. An absorbent article containing the hook strip and a method of making the hook strip are also disclosed.

  • Patent number: 8034431
    Abstract: There is provided a laminate of a thermoplastic backing to a fibrous web. This laminate, for example, could be used as a loop laminate for use in a hook and loop fastening system or an intermittently bonded elastic fibrous laminate. The laminate comprises a thermoplastic backing layer, having a first face and a second face. The backing layer has a plurality of projections extending from at least the first face of the backing. A fibrous web is attached to the backing at the location of at least some of the projections. The thermoplastic material of the backing, at the location of the projections, penetrates into the fibrous web encapsulating at least in part fibers of the fibrous web. The fibrous web preferably penetrates into at least some of the projections. The fibrous web is generally not attached, or very lightly attached, to the backing layer over at least some portion of the distance between adjacent projections.

  • Patent number: 7842021
    Abstract: Absorbent articles with waist seals are disclosed. The seals are formed from folded stacks, discrete segments, or pleated material arranged to provide a resiliently compressible seal that can be located at one or more locations within the absorbent article, e.g., along a central portion of the rear waist region of a diaper. The seals may be constructed from relatively thin materials that (through folding, stacking, pleating, etc.) can provide a resiliently compressible seal that is thick enough and appropriately shaped to conform to the wearer's anatomy well enough to provide the desired sealing. At the same, time, the continuous web material used to form the seal is preferably thin enough to be economically delivered to the manufacturing line in roll form. The seals may be provided in the form of compressed seals that expand when one or more openings are formed in a sealed cavity containing compressed resilient material.

  • Publication number: 20090142577
    Abstract: Composite webs having a structured web attached to a carrier web and methods of manufacturing the composite webs are disclosed. The structured web may include a plurality of structures that protrude from the structured web. The methods may involve delivering a molten polymeric composition onto the outer surface of a forming tool that includes a plurality of depressions formed in the outer surface. The molten polymer enters depressions in the outer surface of the forming tool and is solidified therein such that a plurality of structures are formed in the shape of the depressions. A skin layer of the polymeric composition may extend between the depressions, such that the structured web formed on the forming tool includes a skin layer connecting the structures. The structured web is removed from the forming tool after solidification of the polymeric composition by adhering the structured web to a carrier web using adhesive located between the carrier web and structured web.

  • Publication number: 20080065042
    Abstract: There is provided a disposable garment including a chassis having front and back waist sections. Two sets of side sections connect the front and back waist sections divided into a front side section and a back side section and define a continuous waist of the disposable absorbent garment. The leg openings are defined by the lower portion of the back side sections and the central crotch region of the chassis. The side sections form expandable waist and leg openings. A fastening element located a side section forms a refastenable closure when engaged with the chassis and with the back side sections creating the fitted waist and leg openings. The front side section is generally of a smaller width dimension so that it can be easily folded into the side of the diaper and does not form a part of either the fitted leg or waist openings.
