Self-texturing absorbent structures and absorbent articles made therefrom

A novel absorbent structure is disclosed in which an initially flat, dense structure becomes a three-dimensional, high bulk, channeled structure upon wetting. The structure offers unusually high directionality in fluid transport to improve the distribution of fluid in longitudinal articles. The self-bulking of the wetted article can also lead to improved fit in articles such as diapers and in general increases the void volume of the wetted article for high absorbent capacity.

Intake/distribution material for personal care products

There is provided an intake/distribution layer for personal care products which is a co-apertured distribution layer and a transfer delay layer between them. The co-apertured distribution and transfer delay layer can serve to store liquid and release it to an absorbent core in a personal care product at a rate at which the core can absorb. This ability to accept irregular and large flow rates makes the layer of this invention particularly well suited for “gush” management. The distribution layer is preferably an airlaid fabric and the transfer delay layer is preferably a spunbond fabric and they are co-apertured using a pin density of preferably about 2.5 pins/cm 2 .

Absorbent article with fluid intake intensifier

Disposable absorbent articles having a fluid intake pledget. Disposable absorbent articles such as feminine hygiene products (e.g., sanitary napkins and panti-liners) and incontinence products having an airlaid, lofty pledget of a low density, nonwoven material for intake of body fluids.

Absorbent products with improved vertical wicking and rewet capability

The present invention relates to an absorbent core for use in an absorbent article and methods to make the absorbent core and absorbent articles. The absorbent core has a discrete wicking layer made with compressible fibers such as eucalyptus or chemically treated fibers. The absorbent core and articles made with it have improved vertical wicking capacity and superior rewet characteristics.

Absorbent article with bimodal acquisition layer

A disposable absorbent garment including a topsheet, a backsheet, a storage layer, and an acquisition layer is disclosed. The acquisition layer lies between the topsheet and the storage layer, and includes at least two yarns oriented generally parallel with the longitudinal axis of the article, with an acquisition channel between each adjacent pair of yarns. The acquisition channels provide free volume for temporary fluid storage until the fluids can be absorbed by the storage layer and allow fluids to move to the longitudinal ends of the article. The yarns store fluids until they are absorbed, and wick fluids away from the topsheet to keep the user dry. Each yam may have properties specifically tailored to provide particular benefits depending on each yarn's location in the garment. The absorbent garment using such an acquisition layer is comfortable, highly absorbent, and economical to produce.

Nonabsorbent surge layer having discrete regions of superabsorbent and method for making

This invention is a surge material having permanent storage properties that results in faster intake and greater saturation capacity and reduced fluid flowback. More specifically the invention is a surge material with a superabsorbent material printed on in a pattern of discrete regions. The objective of the invention is obtained by printing, or other known application process, a liquid superabsorbent precursor solution containing a crosslinkable composition onto a surge material and then curing the printed surge material to crosslink the polymers to get a surge material having discrete regions of superabsorbent material in the surge material. This invention is also useful in making an absorbent core of an absorbent article with improved strength, increased absorbency, and decreased shedding of superabsorbent material.

Absorbent article including an absorbent layer having a plurality of spaced beam elements

The present invention generally relates to absorbent sanitary napkins and in particular to a sanitary napkin including an absorbent layer having a plurality of spaced beam elements for promoting enhanced fluid wicking within the sanitary napkin.

Absorbent product with low dryness index

The embodiments provide an absorbent garment, such as a disposable diaper, incontinent pad, sanitary napkin, and the like, that has an absorbent core that provides for a long term dryness profile. The dryness profile reflects real world long term usage of absorbent products. Such new absorbent garments can be constructed with absorbent cores containing synthetic fibers and super absorbent particulates.

Absorbent article having a fluid pumping element

An absorbent article useful for absorbing bodily fluids discharged by the wearer of the article is provided. The absorbent article comprises a fluid pervious topsheet, a fluid impervious backsheet affixed to the topsheet, an absorbent core disposed between the topsheet and the backsheet, and a resilient tubular member disposed between the topsheet and the backsheet for transporting the fluids to a predetermined region of the core. The tubular member has a plurality of fluid inlets and a plurality of fluid outlets, the inlets and outlets providing fluid communication between the interior and exterior of the tubular member. Discharged fluids may be transported from regions adjacent the inlets into the interior of the tubular member, and thereafter through the outlets to the predetermined regions of the core adjacent the outlets, thereby rapidly transporting the fluids to the predetermined region of the core. The inlets are normally open and the outlets are normally closed, however compression of the tubular member causes the inlets to close and the outlets to open, thereby permitting the desired fluid movement. Decompression and compression of the tubular member may be accomplished by the normal bodily movements of the wearer.
