Abstract:
Absorbent members and methods of making the same are disclosed. In one embodiment, the absorbent member is a unitary absorbent fibrous web having a density profile through its thickness. In one embodiment, the density profile of the fibrous web is skewed toward one of the surfaces of the fibrous web. In such embodiments, the maximum density of the web may be located outside of the central 30% zone of the thickness of the web. In one embodiment, the method involves subjecting a precursor web to at least one cycle (or pass) through a mechanical deformation process. Typically, the method involves subjecting the precursor web to multiples cycles (or passes) through a mechanical deformation process.
Abstract:
Absorbent members, especially bulked absorbent members, and methods of making the same are disclosed. The absorbent member may be in the form of a unitary absorbent fibrous layer comprising at least some cellulose fibers. The unitary absorbent fibrous layer is at least partially stratified through its thickness. The absorbent member may also have a plurality of discrete deformations, such as depressions and/or apertures in its surfaces. The method involves subjecting a precursor web to at least one cycle (or pass) through a mechanical deformation process. The mechanical deformation process utilizes a first forming member and a second forming member that form a nip therebetween through which the precursor web is passed. The first and second forming members are moving at different speeds relative to each other when they come together to form the nip.
Abstract:
The present disclosure is directed to disposable absorbent articles comprising a structured fibrous web, the structured fibrous web comprising thermally stable, hydrophilic fibers that are thermally bonded together using heat producing a base substrate that is thermally stable. The base substrate is textured via mechanical treatment to increase its thickness and optionally modified via over bonding to improve its mechanical and fluid handling properties. The structured fibrous web provides optimal fluid wicking and fluid acquisition capabilities and is directed toward fluid management applications.
Abstract:
An electrical cable of the present invention comprises a plurality of spaced, parallel flat conductors. Each of the plurality of flat conductors was previously integral with each immediately adjacent flat conductor. A dielectric material is holds the conductors in the spaced, parallel relationship. The dielectric material can be a polymer film, a nonwoven, or other polymer materials such as PTFE, or expanded PTFE. The cable of the present invention is made by providing first and second webs of dielectric materials and a third sheet of conductive material. The first and second web materials are bonded to the third sheet of conductive material in a face-to-face layered relationship thereby forming a bonded laminate. The bonded laminate is then incrementally stretched to separate the sheet of conductive material in to spaced, parallel flat conductors.

Abstract:
A disposable absorbent article may comprise a web that may be folded over at a first fold line forming a first hem, folded over at a second fold line forming a second hem, and folded over at a third fold line and attached in the front and back waist regions to form a first side flap. The web may be folded over at a fourth fold line and attached in the front and back waist regions to form a second side flap. The absorbent article may also comprise a second elastic gathering member attached at or adjacent the side edge of the absorbent article. Also, the absorbent article may comprise laterally opposing deployable belt ears attached to the web in at least one of the waist regions. Each belt ear may be disposed laterally inward until being deployed laterally outward so as to project laterally outward beyond the respective distal edges of the side flaps.
Abstract:
A method and apparatus is provided which uses activation members for incrementally stretching a web at a low strain rate. The activation members include an activation belt and a single activation member wherein the activation belt and single activation member comprise a plurality of teeth and grooves that complement and engage one another at a depth of engagement in a deformation zone. The depth of engagement can be controlled to increase linearly over at least a portion of the deformation zone such that a web interposed between the activation belt and the single activation member in the deformation zone is incrementally stretched at a low rate of strain.
