20220233364 · 2022-07-28 ·

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.

Absorbent article and absorbent core forming channels when wet

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.

The present invention prevents an absorbent body from twisting and splitting while maintaining the capability of fitting onto the buttocks of a wearer even when the absorbent body has a low fabric weight. The absorbent body (4) has a large number of compressed parts (20, 20, . . . ) formed in a region other than a region that extends in a widthwise center section along the longitudinal direction and includes portions corresponding to a body fluid excretion part (H) and the intergluteal cleft of the wearer. A region including a portion corresponding to the intergluteal cleft is an easily deformable region (21) without compressed parts (20). The easily deformable region (21) extends to an intermediate position in the longitudinal direction and does not reach the rear end of the absorbent body (4). The region extending behind the easily deformable region (21) to the rear end of the absorbent body (4) has compressed parts (20) formed thereon.
