Appl. No.:

10/074215

Inventors:

Andrew Baker - Alpharetta GA

Assignee:

Paragon Trade Brands, Inc. - Norcross GA

International Classification:

A61F 1315

US Classification:

156265, 156269, 156510, 156521, 156552, 264112, 264122

Abstract:

The present invention generally relates to a method and apparatus for forming an absorbent garment and an absorbent composite core. The absorbent composite core preferably is comprised of at least four layers, whereby two of the layers are outer layers, (an upper layer and a lower layer), one of the inner layers is a central fibrous layer containing a mixture of tow fibers and SAP, and the other inner layer is at least one layer selected from an acquisition layer, a distribution layer, an additional fibrous layer optionally containing SAP, a wicking layer, a storage layer, a dryness layer, a softness layer, or combinations and fragments thereof.

International Classification:

G01R 2726

US Classification:

324663, 324671, 604358, 83 74, 83364

Abstract:

A system and method for adjusting the targeting of superabsorbent material in absorbent cores based on the timing of a cutting device are disclosed herein. After targeting superabsorbent material into a segment of absorbent core material, a first sensor is used to determine a change in concentration of superabsorbent material over the length of the segment, or alternatively, a rate-of-change in the concentration is determined. The change in concentration, or rate-of-change, can be interpreted as the timing of the superabsorbent material targeting. A second sensor is used to determine the timing of a cutting device used to separate the segment from the remaining absorbent core material. The timing of the targeting of the superabsorbent material can then be synchronized with the timing of the cutting device for targeting of superabsorbent material in subsequent segments of the absorbent core material.

Assignee:

Paragon Trade Brands - Norcross GA

International Classification:

A61F 1315

US Classification:

604368

Abstract:

An absorbent composition providing unexpectedly high fluid capacity with minimal gel-blocking, articles comprising the absorbent composition and methods of preparing the absorbent composition are disclosed. The absorbent composition optionally comprises a surface crosslinked polymer disbursed within a fibrous matrix of wettable fibers. The surface crosslinked polymer has an FVAUL value of at least about 60 cc after 10 minutes.

Inventors:

Andrew Baker - Lawrenceville GA

Assignee:

Paragon Trade Brands, Inc. - Norcross GA

International Classification:

A61F 1315

US Classification:

604378

Abstract:

An absorbent article and a method for preparing an absorbent article is disclosed. The absorbent article has a core comprised of pulp, a polymer or a combination thereof. The absorbent article conforms to a certain Distribution Index (DI) or a certain Distribution Index (DI) profile that confers one or more superior properties to the core and in turn to the absorbent article, such as superior absorbency efficiency and superior cost efficiency. The method for preparing the absorbent article uses DI values (e. g. , DI , DI , DI and DI ) or a DI profile as design parameters for providing absorbent articles having one or more superior characteristics.

International Classification:

B27N 304

US Classification:

425 811, 425 801, 264112, 264121

Abstract:

An apparatus and a method for preparing an absorbent article is disclosed. The apparatus has at least two forming surfaces which differ in terms of air permeability to allow the selective placement of fibrous material. The forming surface comprises a perforated forming screen. The forming screen has multiple zones with different amounts of open area through which air may pass. Particles carried in the air which flows through the open area are deposited on different zones of the forming screen resulting in different basis weights corresponding to the different air permeabilities. The apparatus and method thus provide an article having optimal zoned absorbency in a cost-effective manner.

International Classification:

A61F013/15

US Classification:

604369

Abstract:

The Invention relates to absorbent articles, such as diapers, incontinence products, training pants, sanitary napkins, and the like, providing superior strikethrough and rewet characteristics, and methods of preparing the absorbent articles. The absorbent articles comprise at least a topsheet, backsheet, absorbent core, and fluid handling layer, and the article has a third insult Strikethrough of less than about 45 seconds, and a third insult Rewet of less than about 35 grams.

Inventors:

Andrew Baker - Lawrenceville GA, US

Assignee:

Paragon Trade Brands, Inc. - Norcross GA

International Classification:

B67D 5/64

US Classification:

222161, 604368, 222197, 222226

Abstract:

An apparatus and method for depositing particulate matter onto a supply of absorbent core fibrous substrate material are disclosed. The apparatus has a feed tray that has an inlet for receiving a supply of particulate matter. At least part of a lower pan of the feed tray is a slideable shuttle pan that has an outlet edge located near a supply of absorbent core fibrous substrate material that is moving in a machine direction. The supply of particulate matter passes over the outlet edge to exit the feed tray. A mechanism operates the shuttle pan through a range of motion having a forward stroke and a backward stroke. During the forward stroke, the outlet edge follows the supply of absorbent core fibrous substrate material.

Abstract:

The present invention relates generally to an absorbent core for an absorbent article, and more particularly to an absorbent core having zoned absorbency due to specific placement of adhesives or specific lack of adhesive. Such absorbent cores provide the flexibility of creating precise zoning of particular properties throughout the core, and they provide improved comfort and fit.
