Absorbent article suppressing occurrence of malodor after use while preventing a rash on a wearer's skin. The absorbent article includes an absorbent body, and a fumaric acid-supported sheet disposed on a skin surface side of the absorbent body. The fumaric acid-supported sheet is a sheet which supports fumaric acid particles having an average particle diameter of 30 μm or less, and/or a sheet in which at least a part of constituent fibers is coated with fumaric acid. When being in contact with the body fluid or the like, fumaric acid is not immediately but slowly dissolved so that alkalization at the area around fumaric acid can be prevented over a long period of time. In addition, fumaric acid has an action of inhibiting proliferation of putrefactive bacteria and, therefore, can prevent occurrence of malodor from the absorbent article having absorbed the body fluid or the like.

Disclosed is an absorbent core composite for a disposable absorbent article. The absorbent composite has a first fabric, a body side second fabric, and a plurality of aggregates of superabsorbent particles (SAP) situated between the first fabric second fabric. About each of a plurality of the SAP aggregates, an arrangement of spaced apart bond sites secure the second fabric to the first fabric and form a pocket in which the SAP aggregate is secured between the first fabric and the second fabric. The body side second fabric is a bulky nonwoven including fibers that entangle at least some particles in the SAP aggregate.

A method of forming an absorbent body may comprise moving a first covering material in a machine direction, moving a reinforcing material in the machine direction and combining the reinforcing material with the first covering material, the reinforcing material having a top side and a bottom side, applying absorbent material comprising superabsorbent particles to the top side of the reinforcing material, moving a second covering material in the machine direction and combining the second covering material with the first covering material and the reinforcing material to form a laminate structure of the first covering material, the reinforcing material, and the second covering material, with the first covering material disposed underneath the reinforcing material and the second covering material disposed on top of the reinforcing material, and embossing the laminate structure.

Multi-layered absorbent bodies and methods of manufacture are disclosed. An absorbent body may comprise a top, liquid permeable covering material, a bottom covering material, a reinforcing material disposed between the top covering material and the bottom covering material, the reinforcing material bonded directly to the top covering material by a first adhesive layer and bonded directly to the bottom covering material by a second adhesive layer, and superabsorbent material disposed between the top covering material and the bottom covering material, wherein between about 30% and about 85%, by weight, of the total amount of superabsorbent material disposed between the top covering material and the bottom covering material is stabilized within the reinforcing material, as determined according to the SAM Stabilization Location Test Method.

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.

An absorbent article comprising an absorbent core sandwiched between a liquid permeable topsheet and a liquid impermeable back-sheet, and an acquisition distribution system positioned between said topsheet and said absorbent core, wherein the absorbent core comprises absorbent material selected from the group consisting of cellulose fibers, superabsorbent polymers and combinations thereof, wherein said absorbent material is contained within at least one core wrap substrate enclosing said absorbent material, and wherein a top layer of said core wrap is adhered to a bottom layer of said core wrap to form one or more channels substantially free of said absorbent material, wherein said channels have a length extending along a longitudinal axis and the absorbent core has a length extending along said longitudinal axis and wherein the length of said channels is from 10% to 95% of the length of said absorbent core and wherein said channels each follow a substantially continuous path such as from a first end of a channel to a second end of the same channel wherein the acquisition distribution system is multi-layered and comprises at least one spunbond layer and at least one meltblown layer, and wherein said acquisition distribution system is positioned between said absorbent core and said topsheet such that said spunbond and/or meltblown layers are in direct contact with said absorbent core and said topsheet.
