COMPOSITE HAVING IMPROVED IN-PLANE PERMEABILITY AND ABSORBENT ARTICLE HAVING IMPROVED FLUID MANAGEMENT
The present disclosure features a feminine hygiene product, including a nonwoven layer including polymeric fibers and/or filaments; a crosslinked cellulose layer including crosslinked cellulose fibers; wherein the crosslinked cellulose layer is positioned opposed to the nonwoven layer (e.g., without an intervening layer different from the crosslinked cellulose layer and the nonwoven layer; in some embodiments, the crosslinked cellulose layer is immediately adjacent to the nonwoven layer); and an interfacial region between the nonwoven layer and the crosslinked cellulose layer, the interfacial region including physically entangled polymeric fibers and/or filaments from the nonwoven layer and crosslinked cellulose fibers from the crosslinked cellulose layer. The nonwoven layer and the crosslinked cellulose layer of the composite fabric are mechanically inseparable in a dry state.
Absorbent Composite, an Absorbent Article Employing the Same, and Methods, Systems, and Apparatus for Making the Absorbent Composite and/or Article
An absorbent core composite is disclosed for incorporation into a disposable absorbent article. The composite includes a first material layer and a second material layer (preferably nonwoven) partially secured to the first material layer to define at least one pocket therebetween. Preferably, multiple pockets are defined, except in the case of where a generally uniform layer or bed of absorbent is preferred or better suited fro the application. The pocket is said have a fixed initial volume. Further, an aggregate of absorbent particles is provided in the pocket(s) to occupy a portion of the fixed initial volume. The absorbent particles are preferably SAP particles and is characterized by a dry volume associated with a dry state and a swell volume associated with a liquid saturation state. In respect to or for the pocket, the aggregate is characterized by a collective dry volume and a collective swell volume, wherein the pocket has an initial configuration that retains the aggregate therein.
Disposable absorbent article having breathable side flaps
A disposable absorbent article with a water-permeable covering sheet, a water-impermeable center sheet, and an absorbent core disposed therebetween is disclosed herein. The absorbent article includes a pair of side flaps comprising a first side flap and an opposing second side flap; each of the first and second side flaps being made from a distinct layer of material that is not an extension of the water-permeable covering sheet or the water-impermeable center sheet. The distinct layer of material is doubled over to form a first layer comprising a first layer proximal edge, and a second layer comprising a second layer proximal edge, wherein the first layer and the second layer enclose an elastic strand, and wherein the first layer is attached to the second layer.
Absorbent composite, an absorbent article employing the same, and methods, systems, and apparatus for making the absorbent composite and/or article
An absorbent core composite is disclosed for incorporation into a disposable absorbent article. The composite includes a first material layer and a second material layer (preferably nonwoven) partially secured to the first material layer to define at least one pocket therebetween. Preferably, multiple pockets are defined, except in the case of where a generally uniform layer or bed of absorbent is preferred or better suited for the application. The pocket is said have a fixed initial volume. Further, an aggregate of absorbent particles is provided in the pocket(s) to occupy a portion of the fixed initial volume. The absorbent particles are preferably SAP particles and is characterized by a dry volume associated with a dry state and a swell volume associated with a liquid saturation state. In respect to or for the pocket, the aggregate is characterized by a collective dry volume and a collective swell volume, wherein the pocket has an initial configuration that retains the aggregate therein.
ABSORBENT ARTICLE
A system of absorbent articles is described. The system includes a first absorbent article having a first pad length, a first pad width, and a first core width; a second absorbent article having a second pad length, a second pad width, and a second core width; a third absorbent article having a third pad length, a third pad width, and a third core width; and a product selection guide identifying the first, second, and the third absorbent articles. Each of the first, second, and the third absorbent articles has a caliper of 3-6 mm The percent difference in pad attributes between the first, second, and the third absorbent articles is at least one of: (i) about 8 to about 29 in pad length; (ii) about 7 to about 25 in pad width; and (iii) about 8 to about 30 in core width.
FLUID DISTRIBUTION MATERIAL FOR ABSORBENT ARTICLES
A fluid distribution material for an absorbent article includes a formed film that includes a first side and a second side opposite the first side. The first side includes a plurality of elongated ridges extending from a first land area, a plurality of valleys defined by adjacent elongated ridges and the first land area, and a plurality of primary apertures located at bottoms of the valleys. The second side includes a plurality of apertured protuberances extending from a second land area. Each of the protuberances includes a continuous sidewall extending from the second land area to a distal end that includes a secondary aperture substantially aligned with a primary aperture. The formed film has a thickness greater than about 0.9 mm under a pressure of 0.071 psi, and a thickness greater than about 0.3 mm under a pressure of 0.6 psi.
ABSORBENT CORE AND ABSORBENT ARTICLES COMPRISING SAID CORE
