A disposable undergarment including an absorbent core assembly and methods of making the same is disclosed. The undergarment includes a chassis holding the core assembly. The chassis includes a front section, a crotch section and a rear section. The core assembly is located in the crotch section, with portions of it extending into the front and rear sections. A large plurality of closely spaced elastic threads extends across the full width of the undergarment in the front and rear sections. The elastic threads are broken in the areas of the core assembly. The core assembly includes a first section of a slow acting but high absorbency SAP in pockets thereof and an underlying second section of a fast acting but lower absorbency SAP in pockets thereof.

DISPOSABLE DIAPERS

Disposable absorbent diapers are provided with improved comfort, fit and liquid transportation. The absorbent core of the disposable absorbent diapers includes at least one absorbent structure having a substrate layer and an absorbent layer with channels.

METHODS OF MAKING ABSORBENT CORES AND ABSORBENT PRODUCTS USING SUCH CORES
20180140481 · 2018-05-24 ·

An absorbent core assembly for use in a product for absorbing a liquid is disclosed. The core assembly has a first section and a second section. The first section is a quilted porous material that contains a slow acting but high absorption capacity SAP therein. The, second section is a quilted porous material that contains a fast acting but lower absorption capacity SAP therein. The first and second sections are in fluid communication with each other, whereupon a liquid which is exposed to the core assembly flows through the first section to the fast acting SAP in the second section to be absorbed quickly and rapidly by the fast acting SAP therein, while the slow acting SAP desorbs or takes liquid away from the fast acting SAP as well as absorbing the liquid itself to thereby trap the liquid in the core assembly.

BODY-WEARABLE MEDICAL DEVICE COMPRISING A SUPERABSORBENT SUBSTANCE
20240390197 · 2024-11-28 ·

A body-wearable medical device has a medical device housing having a transcutaneous element configured for being at least partially inserted into a patient's body at an insertion site during use of the body-wearable medical device. A base is configured for reversibly attaching the body-wearable medical device during its use to a patient's skin. The base has a first side that faces the patient's body and that also has an adhesive for adhering the body-wearable medical device to a patient's skin. For reducing a likelihood of contamination by body fluid flowing out of the insertion lesion, the base on its first side also has a superabsorbent substance and at least one fluid channel. The fluid channel is configured to guide body fluid from the insertion site to the superabsorbent substance.

ABSORBENT PANT WITH ADVANTAGEOUSLY CHANNELED ABSORBENT CORE STRUCTURE AND BULGE-REDUCING FEATURES
20180021187 · 2018-01-25 ·

A disposable absorbent pant having a belt structure that encircles the wearer's waist, with front and rear belt portions, and a longitudinally channeled absorbent core structure, is disclosed. The channels are extended so as to underlie at least one of the front and rear belt portions, thereby providing added structural support to restrain the absorbent core and reduce the likelihood of undesirable bulging in the front and/or rear of the pant while it is worn, after the core has absorbed liquid and stiffened longitudinally as a result of the channeled structure.

Absorbent article

To prevent or suppress roughness of the skin of a wearer by configuring an absorbent article so as to quickly absorb a body fluid into an absorber, for example, configuring a diaper so as to quickly absorb loose stool into an absorber. An absorbent article includes a liquid-holding absorber and a liquid pervious top sheet on a skin-facing surface side of the absorber. An absorbent Q mainly containing glycerin is provided on an intermediate sheet that transfers at least a body fluid that has passed through the top sheet to the absorber.

ABSORBENT PRODUCTS AND ABSORBENT CORE FOR USE IN SAME

An absorbent core assembly for use in a product for absorbing a liquid is disclosed. The core assembly has a first section and a second section. The first section is a quilted porous material that contains a slow acting but high absorption capacity SAP therein. The, second section is a quilted porous material that contains a fast acting but lower absorption capacity SAP therein. The first and second sections are in fluid communication with each other, whereupon a liquid which is exposed to the core assembly flows through the first section to the fast acting SAP in the second section to be absorbed quickly and rapidly by the fast acting SAP therein, while the slow acting SAP desorbs or takes liquid away from the fast acting SAP as well as absorbing the liquid itself to thereby trap the liquid in the core assembly.

Absorbent article
09700464 · 2017-07-11 · ·

An absorbent article which has in a longitudinal direction from the front side to the rear side a front waist region, a rear waist region and a crotch region located between the front and rear waist regions. An absorbent sheet is provided between a topsheet and a second sheet which includes at least one liquid-pervious sheet having sandwiched therein an absorbent polymer that is present between a topsheet and a second sheet. The second sheet has a higher liquid diffusibility than the topsheet, the topsheet, a backsheet, an absorption body and the second sheet are disposed across the front waist region, the crotch region and the rear waist region, and the absorbent sheet is disposed in at least a part of the rear waist region.

Core assembly for absorbing liquids

An absorbent core assembly for use in a product for absorbing a liquid is disclosed. The core assembly has a first section and a second section. The first section is a quilted porous material that contains a slow acting but high absorption capacity SAP therein. The, second section is a quilted porous material that contains a fast acting but lower absorption capacity SAP therein. The first and second sections are in fluid communication with each other, whereupon a liquid which is exposed to the core assembly flows through the first section to the fast acting SAP in the second section to be absorbed quickly and rapidly by the fast acting SAP therein, while the slow acting SAP desorbs or takes liquid away from the fast acting SAP as well as absorbing the liquid itself to thereby trap the liquid in the core assembly.

ABSORBENT ARTICLE WITH ABSORBENT CORE STRUCTURE HAVING A SHAPED INNER CORE LAYER

A disposable absorbent article having a topsheet, a backsheet, an absorbent core structure disposed between the topsheet and backsheet, and a flex bond channel region. The absorbent core structure includes an upper nonwoven layer having polymer fibers, a lower nonwoven layer having polymer fibers, and an inner core layer disposed between the upper and lower nonwoven layers. The flex bond channel region has a dry channel depth of from about 1.0 mm to about 4.5 mm and a channel width of from about 1.0 mm to about 3.0 mm. The flex bond channel region has a Dry MD Bending Resistance of less than about 0.04 N/mm. The inner core layer comprises an outer absorbent zone that substantially surrounds a central absorbent zone. The basis weight of the central absorbent zone is greater than the basis weight of the outer absorbent zone.
