A multiple use absorbent article includes a chassis absorbent unit having a chassis topsheet, a chassis backsheet, and a chassis absorbent core sandwiched between the chassis topsheet and the chassis backsheet. The article also includes an absorbent insert bonded to the chassis absorbent unit, a removable portion of the absorbent insert configured to be selectively removable from the chassis absorbent unit, wherein the absorbent insert includes an insert top-sheet, an insert backsheet, and an insert absorbent core sandwiched between the insert topsheet and the insert backsheet. The absorbent insert further includes a line of weakness that provides for separation of the absorbent insert into a removable portion configured to be removed from the chassis absorbent unit, and a resident portion that remains bonded to the chassis absorbent unit.
Absorbent cores and methods for forming absorbent cores
Pulpless absorbent cores and methods of manufacture are disclosed. A first exemplary absorbent core may comprise a carrier sheet having a first edge region, a central region, and a second edge region and particulate material disposed on the carrier sheet through the first edge region, the central region, and the second edge region. The absorbent core may additionally have an absorbent core width and the central region may have a central region width, and the central width may comprise between 33% and 75% of the absorbent core width. Further, the central region may comprise an average basis weight of particulate material that is at least 110% of an average basis weight of particulate material within at least one of the left edge region and the right edge region.
ABSORBENT ARTICLE WITH LEG CUFFS
A disposable absorbent article may include a chassis that includes a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet; and a leg gasketing system. The leg gasketing system may include an inner cuff and an outer cuff; the inner cuff may include an inner cuff folded edge and an inner cuff material edge and the outer cuff may include an outer cuff folded edge and an outer cuff material edge such that the web of material is folded laterally inward to form the outer cuff folded edge and folded laterally outward to form the inner cuff folded edge, and the leg gasketing system further including a leg gasketing system pocket with an opening on an inboard longitudinal edge of the leg gasketing system pocket. The disposable absorbent article also includes at least one channel in the absorbent core.
DISPOSABLE DIAPER
A disposable diaper in which an absorbent body (7) is provided on a crotch part of a pants-shaped exterior member (2), wherein the absorbent body (7) is adhered to a skin-facing side of the exterior member (2) at a first adhering region (14), an inner sheet (5) and an outer sheet (6) of the exterior member (2) are adhered to each other at a second adhering region (16), the second adhering region (16) includes a second middle adhering region (16M) provided at the crotch part, a second central front adhering region (16CF) located anterior thereto so as to overlap with the first adhering region (14) and a second central rear adhering region (16CB) located posterior thereto so as to overlap with the first adhering region (14), and second front non-adhering regions (17F) are formed on both sides of the second central front adhering region (16CF) in the width direction so as to overlap with the absorbent body (7) and/or second rear non-adhering regions (17B) are formed on both sides of the second central rear adhering region (16CB) in the width direction so as to overlap with the absorbent body (7).
Absorbent article with core-to-backsheet glue pattern comprising two glues
An absorbent article comprises a topsheet on the wearer-facing side, a backsheet on the garment-facing side, and an absorbent core positioned between the topsheet and the backsheet. The absorbent core comprises an absorbent material comprising a superabsorbent polymer, a core wrap enclosing the absorbent material, and a first channel disposed on one side of the longitudinal axis and a second channel disposed on the other side of the longitudinal axis.
Absorbent article with channels and method for manufacturing thereof
A method for manufacturing an absorbent article, said method comprising guiding a first sheet material along a rotating member, wherein a surface of said rotating member is provided with a pattern with at least one suction zone and at least one non-suction zone; applying an absorbent material on said first sheet material on the rotating member; locally removing the absorbent material applied on at least one attachment portion of the first sheet material located above the at least one non-suction zone, such that at least one remaining portion of the first sheet material located above the at least one suction zone is covered with absorbent material and substantially no absorbent material is present on the at least one attachment portion; applying a second sheet material on top of the absorbent material on the first sheet material.
Method for producing recycled product, recycled resin pellet, and recycled film
A method includes producing recycled products from a plurality of used absorbent articles, each including a top sheet, a back sheet and an absorbent body including absorbent body materials, by recovering a plurality of structural members from the plurality of used absorbent articles. At least one of the top sheet and the back sheet includes a film. The method includes: separating the plurality of used absorbent articles into a plurality of the films and the absorbent body materials; sorting the plurality of films into a plurality of types of recyclable films according to the filler contents of the plurality of films; and forming a plurality of types of recycled resin pellets from the plurality of types of recyclable films.
ABSORBENT ARTICLE WITH IMPROVED CORE AND METHOD OF MAKING
An absorbent article comprising: a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core positioned between said topsheet and backsheet, wherein the absorbent core comprises an absorbent material, said absorbent material comprising cellulose fibers and/or superabsorbent polymers, and wherein said absorbent material is contained within at least one core wrap substrate enclosing said absorbent material therein, wherein the absorbent core further comprises an intermediate layer positioned between a top layer of said core wrap and a bottom layer of said core wrap such that said absorbent material is disposed between said top layer and said intermediate layer and between said bottom layer and said intermediate layer.
Absorbent cores and methods for forming absorbent cores
Pulpless absorbent cores and methods of manufacture are disclosed. A method of forming a pulpless absorbent core may comprise moving a foraminous forming surface having un-masked portions and masked portions in a machine direction, the un-masked portions defining an absorbent core region. The method may further comprise depositing particulate material at a velocity of less than 1200 meters per minute in the absorbent core region while applying a vacuum. The absorbent core region may comprise: a front core region spanning a first half of the absorbent core region and a rear core region spanning a second half, wherein the front core region trails the rear core region in the machine direction, and the masked portions of the foraminous forming surface block airflow through the forming surface to cause greater than 60% of the particulate material deposited in the absorbent core region to locate in the front core region.
