Three dimensional nonwoven materials and methods of manufacturing such materials are disclosed. An absorbent article can include an absorbent body and an outer cover. The absorbent article can also include a fluid-entangled nonwoven material. The absorbent body can be disposed between the fluid-entangled nonwoven material and the outer cover. The fluid-entangled nonwoven can include a first surface and a second surface. The nonwoven material can also include a plurality of nodes extending away from abase plane on the first surface towards the absorbent body. The nonwoven material can further include a plurality of openings extending from the first surface to the second surface through the fluid-entangled nonwoven material. Individual openings of the plurality of openings can be disposed between adjacent nodes of the plurality of nodes.

A method for producing a low density perforated web material having a thickness of at least 0.20 mm, comprising the steps of: providing a layer of low density material having a maximum overall weight per square meter of 75 g/m.sup.2 or less; and processing the low density material between two rollers pressing onto each other to obtain a low density perforated web material, wherein a first roller has protrusions to perforate the low density material, and a second roller rotates at a different speed from that of the first roller and has projecting parts with contact areas arranged to perforate the material with the protrusions, the contact areas being spaced by recesses to receive the material and having larger contact face dimensions than the protrusions, the recesses leaving an impression in relief on the low density polymer material.

In a shaped sheet manufacturing method, it is possible to reliably shape a first sheet even if the tension of the first sheet is reduced at the time of manufacturing the shaped sheet. In a first step, a first sheet is conveyed along an outer peripheral surface of a first roll having a plurality of recessed parts. In a second step, a second sheet is overlapped with the first sheet and conveyed together with the first sheet so that the first and second sheets are held between the recessed parts of the first roll and projection parts of a second roll. In a third step, the first and second sheets having passed between the first roll and the second roll are bonded to each other. In the second step, the tension of the first sheet is made smaller than the tension of the second sheet.

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 comprises first and second substrates and one or more elastic elements disposed at least partially intermediate the substrates. The second substrate is attached to the first substrate and/or to portions of the elastic elements. The absorbent article comprises an adhesive having a first and second pattern of elements disposed on first substrate, and first and second texture zones. The first texture zone comprises a first portion of the substrates, a first portion of the elastic elements, and the first pattern of elements of the adhesive and forms a background pattern in the first portion of the substrates. The second texture zone comprises a second portion of the substrates, a second portion of the one or more elastic elements, and the second pattern of elements of the adhesive and forms a macro pattern in the second portion of the substrates.

The invention relates to a laminated assembly including a support layer (32) and an anti-slip strip (34), the anti-slip strip (34) including an elastomeric material, the support layer (32) and the anti-slip strip (34) being laminated together, the anti-slip strip (34) including a base (34A) and a plurality of protruding elements (34B) extending from the base (34A) and the plurality of protruding elements (34B) protruding from a face (30A) of the laminated assembly (30). The invention also relates to a diaper including such a laminated assembly (30) and a process for manufacturing the laminated assembly (30). The invention also relates to a diaper including such an assembly and a process for manufacturing such an assembly.

The present disclosure relates to methods for printing absorbent article substrates. Printing systems herein may include a first printhead and a second printhead, wherein a substrate advances under the first and second printheads. The first printhead ejects ink onto the substrate to define a first printed zone, and the second printhead ejects ink onto the substrate to define a second printed zone. The first printed zone and the second printed zone together define a printed region. The first and second printed zones may be coterminous along respective edges to define a print stitch line extending in the machine direction. The substrate may then be manipulated proximate the print stitch line during a manufacturing process. Positioning the print stitch line proximate a region subject to manipulation may help hide and/or obscure the print stitch line from view. In turn, noticeable visible results of imprecise and/or inconsistent printing operations may be reduced.

The present disclosure relates to assembling elastic laminates that may be used to make absorbent article components. Methods herein may include an anvil adapted to rotate about an axis of rotation, wherein first and second spreader mechanisms adjacent the anvil roll are axially and angularly displaced from each other with respect to the axis of rotation. During the assembly process, a substrate may be advanced in a machine direction onto the rotating anvil. The first spreader mechanism stretches a first elastic material in the cross direction, and the second spreader mechanism stretches a second elastic material in the cross direction. The stretched first and second elastic materials advance from the spreader mechanisms and onto the substrate on the anvil roll. The combined and elastic materials may then be ultrasonically bonded together on the anvil to form at least one elastic laminate.
