Pulpless absorbent cores and methods of manufacture are disclosed. A method of forming an absorbent core may comprise moving a forming surface in a machine direction, creating a pressure differential across the forming surface, advancing a base carrier sheet on the forming surface in the machine direction, applying a first adhesive onto the base carrier sheet, and applying a first quantity of particulate material onto the first adhesive at a first cross-machine direction width. The method may further comprise depositing a matrix of material onto the first quantity of particulate material at a second cross-machine direction width, the matrix of material comprising a second quantity of particulate material and a second adhesive, wherein the second cross-machine direction width is smaller than the first cross-machine direction width, and wherein the second quantity of particulate material and the adhesive are pre-mixed prior to deposition onto the first quantity of particulate material.

The present invention relates to a method of applying absorbent gelling material (AGM) granules by indirect printing onto an carrier layer for use in an absorbent article, particularly diaper for babies or adults, training pants, pull-up diapers (diaper pants), sanitary napkins, panty liners or the like. These articles typically comprise the carrier layer with the AGM particles together with further layers, making up the complete article.

An absorbent article and method of making the absorbent article are disclosed. The absorbent article having a topsheet, a backsheet, and an absorbent core structure having one or more layers wherein at least one layer is a heterogeneous mass layer, wherein the topsheet and the heterogeneous mass are integrated such that they reside in the same X-Y plane.

An absorbent article and method of making the absorbent article are disclosed. The absorbent article having a topsheet, a backsheet, and an absorbent core structure having one or more layers wherein at least one layer is a heterogeneous mass layer, wherein the topsheet and the heterogeneous mass are integrated such that they reside in the same X-Y plane.

An absorbent core comprising substantially continuous zones of one or more high fluid distribution structures and discontinuous zones of fluid absorption structures surrounding the one or more high fluid distribution structures, wherein the one or more high fluid distribution structures are arranged to distribute fluid across the absorbent core at a speed that is faster than the speed of fluid distribution across the absorbent core by said discontinuous fluid absorption structures, and wherein said continuous zones extend along a path that is substantially parallel to at least a portion of the perimeter of the core, said portion of the perimeter of the core comprising at least a portion of the sides of the core and one of the ends of the core.

Provided are absorbent layers and articles, and methods for making absorbent layers and articles. The absorbent layer is suitable for use in an absorbent article and may include a nonwoven that includes bicomponent fibers and superabsorbent polymer material interconnected within the nonwoven. The absorbent layer according to different embodiment may include a three-dimensional random loop material with superabsorbent polymer material adhered to the three-dimensional random loop material. Absorbent articles may comprise the absorbent layer according to embodiments of the present disclosure. The method for making the absorbent layer includes providing a nonwoven and dosing the nonwoven with superabsorbent polymer material.

Absorbent systems having absorbent cores and acquisition distribution layers, where the absorbent cores have material free zones.

The present invention relates to a nonwoven comprising a first layer comprising a first fiber and a second fiber, and a second layer comprising a third fiber; wherein the first fiber is hydrophobic and the second fiber is hydrophilic, and wherein the second layer is more hydrophilic than the first layer; a method for manufacturing the nonwoven according to the present invention; and an absorbent article comprising a topsheet; and a backsheet joined to the topsheet, wherein the topsheet comprises the nonwoven according to the present invention.

A method for forming an absorbent article including a first absorbent core and a second absorbent core which are superposed on each other, includes feeding a first supporting web along a first feed path in a first feed direction; placing a succession of first absorbent cores on the first supporting web at a preset spacing; feeding a second supporting web along a second feed path in a second feed direction; placing a succession of second absorbent cores on the second supporting web at the preset spacing; coupling the first supporting web to the second supporting web such that each first absorbent core is coupled to a corresponding second absorbent core in a composite web including the succession of first absorbent cores and the succession of the second absorbent cores interposed between the first supporting web and the second supporting web.

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.
