Provided is an absorbent article which includes a top sheet having extruded protrusions and a second sheet bonded to the top sheet and has adequate softness, satisfactory appearance, and yet prevents wrinkles in the top sheet along the MD. The problem is solved by a method of producing an absorbent article including forming the extruded protrusions through embossing of non-woven fabric to be a top sheet transferred by being drawn from downstream of a production line; and then bonding the non-woven fabric and a material of a second sheet in a bonding pattern formed by aligning the material of the second sheet 40 with the back face of the non-woven fabric having extruded protrusions, forming rows of plurality of top-second bonded portions at intervals in the CD in regions between the extruded protrusions adjacent each other in the MD so as to be provided across the center positions of the regions in the CD, and compressing the non-woven fabric in areas between the top-second bonded portions in the rows in the CD without welding of the non-woven fabric and the material of the second sheet.

Method and apparatus for making patterned apertured substrates
11484446 · 2022-11-01 · ·

The present disclosure relates to apparatuses and methods for making patterned apertured substrates that may be used as components of absorbent articles. During the manufacturing processes, a precursor substrate advances in a machine direction between a pattern roll and an anvil roll. The pattern roll rotates about an axis of rotation and includes a plurality of pattern surfaces, wherein the substrate is compressed between the anvil roll and the pattern surfaces of the pattern roll to form discrete bond regions in the substrate. The pattern surfaces on the pattern roll are formed on continuous threads extending circumferentially around the axis of rotation along helical paths parallel with each other. As such, the pattern surfaces press the substrate against the outer circumferential surface of the anvil roll in the different axial locations along the cross direction as the pattern roll rotates when forming the discrete bond regions.

ABSORBENT ARTICLE

An absorbent article according to the present invention having a liquid-permeable top sheet, a liquid-impermeable back sheet, and an absorber disposed between the top sheet and the back sheet includes a first recessed portion configured in a top surface of the absorber facing the top sheet and extending along a first direction and a second recessed portion configured in the top surface of the absorber facing the top sheet so as to intersect the first recessed portion, the second recessed portion extending along a second direction different from the first direction. The first recessed portion and the second recessed portion each have a first area having a shallow depth from the top surface of the absorber to a bottom surface of the first area and a second area having a deeper depth than the first area.

The present invention is intended to prevent cutting of the resilient and elastic members by a welding process. The foregoing issue is solved by passing a first sheet layer, a second sheet layer, and elongated resilient and elastic members continuously disposed in an MD direction between the two sheet layers, between a first roll with joint convex parts provided at circumferential intervals on an outer peripheral surface and a second roll opposed to the first roll, and pressurizing and heating the first sheet layer and the second sheet layer to form sheet joined sections by welding the first sheet layer and the second sheet layer in such a manner as to cross the resilient and elastic members and have MD-direction intervals therebetween, wherein circumferentially continuous grooves are formed on a pressurization surface of the second roll, passage sections of the resilient and elastic members are pressurized and heated in positions including the grooves of the second roll, and non-passage sections of the resilient and elastic members are pressurized and heated in positions not including the grooves of the second roll.

Formed web comprising chads

A formed web comprising discrete three-dimensional elements formed therein, wherein at least some of the discrete three-dimensional elements comprise chads with corresponding apertures, wherein the aperture has a perimeter, wherein the chad has a length, wherein the chads are attached along a portion of the aperture perimeter which forms a connection segment, wherein the connection segment is less than about 50% of the entire aperture perimeter, and wherein the web comprises a film.

Anvil roll with protrusions with outwardly oriented pinched wired arcs
11453175 · 2022-09-27 · ·

The present invention is a roll as may function as an anvil roll that comprises protrusions on its outer surface, that are outwardly or z-directionally oriented arcs of an arc wire such as wavy wire or an axially canted helical coil extending along a length or x-direction, which are pinched perpendicularly to the z- and x-direction. Such anvil rolls may be used to treat materials such as web materials, such as by embossing or bonding these web materials. In a particular application, such rolls may interact with an ultrasonic sonotrode.

THREE-DIMENSIONAL NONWOVEN MATERIALS AND METHODS OF MANUFACTURING THEREOF

Three dimensional nonwoven materials and methods of manufacturing such materials are disclosed. In one embodiment, a method can include providing a precursor web that includes a plurality of fibers and transferring the precursor web to a forming surface having a plurality of forming holes. The method can also include directing a plurality of pressurized fluid streams of entangling fluid in a direction towards the precursor web on the forming surface to move at least some of the fibers into the plurality of forming holes to create a fluid entangled web. The method can further include removing the fluid entangled web from the forming surface such that the at least some of the fibers moved into the plurality of forming holes provide a plurality of nodes. The plurality of nodes can have an anisotropy value greater than 1.0 as determined by the Node Analysis Test Method.
