An absorbent article for menstrual and/or incontinence purposes, having a unique two-layer acquisition and absorbent structure. The cover layer includes a nonwoven material. The absorbent core includes multiple strata including super absorbent, fiber material that is pulp and/or bicomponent fibers, and a binder material. The total thickness of the absorbent article is less than or equal to the thickness of absorbent articles of similar absorbent characteristics. The absorbent article includes various absorbent properties that are improved despite parity or reduction in overall thickness.

The present invention relates to an absorbent core for sanitary products with an absorption matrix which comprises a high proportion of super-absorbing particles, and an absorbent core cover for enveloping the absorption matrix, wherein the absorbent core cover comprises at least one upper side sheet and one bottom side sheet, and the absorbent core cover comprises at least one connection region spaced apart from the edge of the absorbent core in which the upper side sheet and the bottom side sheet are connected to each other. Here, at least the upper side sheet of the absorbent core cover is embodied as a fleece composite with a fixing layer with a low permeability to retain the particles in the absorption matrix, and a transfer layer for acquiring fluid. Moreover, the invention relates to a sanitary product having such an absorbent core, the use of a fleece composite as an absorbent core cover, and a method for manufacturing a fleece composite for the upper side sheet of the absorbent core cover.

An absorbent article includes a first waist region, a second waist region, and a crotch region disposed between the first and second waist regions; and a chassis having a topsheet, a backsheet and an absorbent core. The article also includes a waist feature having a portion extending longitudinally outboard of the chassis in the waist region. The backsheet includes a barrier layer having a maximum length, L.sub.BS. The absorbent core has absorbent material and a maximum length, L.sub.CW. L.sub.CW is substantially the same as L.sub.BS. The absorbent material is disposed in an absorbent material deposition area. The absorbent material deposition area has a maximum length, L.sub.AB, and L.sub.AB is about 90% or greater of L.sub.BS. The first absorbent area lateral edge is disposed a longitudinal distance, D1, from the first barrier lateral edge, and D1 is about 5% or less of L.sub.BS.

An absorbable core of a disposable absorption product, having an upper polyurethane foam layer which is liquid-permeable and a wrapping layer which is capable of absorbing liquid; the wrapping layer comprises an outer part and an inner part; the outer part is a first liquid-permeable sleeve body; the inner part is an accommodating cavity; a lower polyurethane foam layer and a particle layer are provided inside the accommodating cavity; the particle layer is distributed on an upper surface of the lower polyurethane foam layer and is formed by resin particles, organic acid particles and anhydrous bicarbonate particles mixed together. A disposable absorption product comprising said absorbable core is also provided. By integrating polyurethane polymer foam with superabsorbent polymer particles, organic acid particles and anhydrous bicarbonate particles, the absorbable core is good at absorbing and locking liquid, and provides soft and elastic supporting materials which provide great comfort to users.

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 in which an absorber includes an upper auxiliary layer disposed on an uppermost portion and a main absorption layer disposed on a back surface side of the upper auxiliary layer, and the upper auxiliary layer includes a super absorbent nonwoven fabric having a surface exposed to an uppermost surface of the absorber and having a Klemm water absorptiveness of 100 mm or more.

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 has a front side, a back side, a longitudinal axis, a liquid permeable topsheet, a liquid impermeable backsheet and an absorbent core between the topsheet and the backsheet. The absorbent core includes a first type of channels, wherein the top side and the bottom side of the core wrap are bonded to another, and a second type of channels, wherein the top side and the bottom side of the core wrap are not bonded or are less bonded to one another in this second type of channels than in the first type of channels. The absorbent material may also include cellulose and superabsorbent particles.

An absorbent article for personal hygiene comprising a liquid permeable topsheet, a liquid impermeable backsheet, an absorbent core and a fibrous layer. The absorbent core comprises a core wrap and an absorbent material with superabsorbent polymers. The core wrap comprises a top side and a bottom side bonded to one other through one or more areas substantially free of absorbent material. The fibrous layer is at least partially bonded to one of the sides of the core wrap in the area substantially free of absorbent material. When the absorbent material swells, the core wrap forms one or more channels along the area substantially free of absorbent material. The formation of the channel in the absorbent core causes the formation of one or more corresponding ditches in the fibrous layer.

An absorbent core (28) for use in an absorbent article, the absorbent core extending in a transversal direction (x) and a longitudinal direction (y), the absorbent core comprising: a fluid-permeable top layer (41), a bottom layer (42), and a central layer (43) sandwiched between the top layer and the bottom layer. the central layer is a high loft fibrous nonwoven layer, in particular having a density of less than 0.200 g/cc, measured at a pressure of 4.14 kPa. Superabsorbent polymer particles (60) are blended with the fibers of the central layer, except for one, two or more longitudinally-extending channels (26) substantially free of superabsorbent polymer particles. The superabsorbent polymer particles may have a UPM of below 30×10.sup.−7 cm.sup.3.Math.s/g, wherein the UPM is measured by the Urine Permeability Measurement Test described herein.
