A thin absorbent composite is provided wherein a nonwoven support sheet is hydro-entangled with a carded fiber web to provide a nonwoven substrate. The nonwoven substrate is coated with an absorbent layer comprising microfibrillated cellulose-coated superabsorbent polymer particles. A cover layer is placed above the absorbent layer to provide the absorbent composite. A process for manufacturing the absorbent composite and an absorbent article containing the absorbent composite are also provided.

An absorbent article such as a baby diaper comprising a three-dimensional laminate 30 having a first layer 1 intermittently bonded to a second layer 2 by a heterophase polymer. The topsheet comprises three-dimensional protrusions 9 in the first layer 1 which are not bonded to the second layer 2. The heterophase polymer has an enthalpy of fusion of at least 10 J/g. The laminate may be used on the wearer-facing side of the article as topsheet 24 and/or on the garment-facing side as part of the backsheet 26. The first layer may comprise natural fibers.

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 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 and a second type of channels. The first type of channels have bonds with a Static Peel Force Time which is higher than the Static Peel Force Time of the second type of channels.

An absorbent article has a front side, a back side, a longitudinal axis and includes a liquid permeable topsheet on the wearer-facing side, a liquid impermeable backsheet on the garment-facing side, and an absorbent core between the topsheet and the backsheet. The absorbent core includes a core wrap having a top side and a bottom side, an absorbent material having a deposition area between the top side and the bottom side of the core wrap, and at least two channels substantially free of absorbent material within the deposition area. In a first type of channels, the top side and the bottom side of the core wrap are bonded to each other. In a second type of channels, the top side and the bottom side of the core wrap are not bonded or are less bonded to each other than in the first type of channels.

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 includes an absorbent element obtained by wrapping an absorbent body in a wrapping sheet, wherein the absorbent body is obtained by mixing and accumulating fibers and high absorbent polymer particles and includes an impregnation layer impregnated with a hot melt adhesive having melt viscosity of 1,000 to 6,000 mPa.Math.s on at least one side of a front face side and a back face side thereof. A part of an internal surface of the wrapping sheet facing the impregnation layer is bonded to an external surface of the impregnation layer through an adhesive layer made of a hot melt adhesive having melt viscosity within a range of 4,000 to 9,000 mPa.Math.s and having higher melt viscosity than melt viscosity of the hot melt adhesive impregnated into the impregnation layer.

The present invention generally relates to a diaper core, specifically a triple leak guard diaper core (1) for infant and adult, comprising: a center core (10) comprising liquid absorbing material (12) and a plurality of hollow sections (14) disposed on the core (10) longitudinally, allowing the core (10) to bend upward or forming a U-channel, and a center core top surface (CCTS) is provided facing a liquid discharge source (16); at least one layer of bottom core wrap (16) encapsulates the center core (10) with a bottom core gap (BCG) disposed on the center core top surface (CCTS); at least one layer of top core wrap (18) is disposed on the bottom core gap (BCG) and the bottom core wrap (16); and at least one layer of acquisition distribution layer (20) is disposed on the top core wrap (18).

An absorbent article comprising an absorbent core having at least two longitudinally extending channel-forming areas and a wetness indicator. The core wrap comprises a top side and a bottom side, which are attached to each other through areas substantially free of absorbent material, so that when the absorbent material swells upon absorption of a liquid the core wrap forms channels along these areas substantially free of absorbent material.

An absorbent core for use in an absorbent article, the absorbent core extending in a transversal direction and a longitudinal direction. The absorbent core includes a fluid-permeable top layer, a bottom layer, and a central layer between the top layer and the bottom layer. The central layer may be a high loft fibrous nonwoven layer, in particular having a density of less than about 0.200 g/cc, measured at a pressure of 4.14 kPa. Superabsorbent polymer particles may be blended with the fibers of the central layer, except for one or more longitudinally-extending channels substantially free of superabsorbent polymer particles.
