ABSORBENT ARTICLES AND METHODS OF MAKING
An absorbent article comprising an absorbent core sandwiched between a liquid permeable topsheet and a liquid impermeable back-sheet, and an acquisition distribution system positioned between said topsheet and said absorbent core, wherein the absorbent core comprises absorbent material selected from the group consisting of cellulose fibers, superabsorbent polymers and combinations thereof, wherein said absorbent material is contained within at least one core wrap substrate enclosing said absorbent material, and wherein a top layer of said core wrap is adhered to a bottom layer of said core wrap to form one or more channels substantially free of said absorbent material, wherein said channels have a length extending along a longitudinal axis and the absorbent core has a length extending along said longitudinal axis and wherein the length of said channels is from 10% to 95% of the length of said absorbent core and wherein said channels each follow a substantially continuous path such as from a first end of a channel to a second end of the same channel wherein the acquisition distribution system is multi-layered and comprises at least one spunbond layer and at least one meltblown layer, and wherein said acquisition distribution system is positioned between said absorbent core and said topsheet such that said spunbond and/or meltblown layers are in direct contact with said absorbent core and said topsheet.

ABSORBENT CORE, ARTICLES COMPRISING SAID CORE, AND METHODS OF MAKING
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.

Absorbent article with an absorbent core having two longitudinally extending side regions and a longitudinally extending central region between said side regions and method for manufacturing said absorbent article
An absorbent article has a longitudinal direction, a transverse direction and a thickness direction, and includes a fluid permeable topsheet, a fluid impermeable backsheet and an absorbent core enclosed between the topsheet and the backsheet having, in the longitudinal direction, a front section, a rear section and a crotch section between the front section and the rear section. The absorbent core has two longitudinally extending side regions and a longitudinally extending central region between said side regions. The central region and the side regions are spaced apart in the transversal direction by longitudinally extending channel regions. Furthermore, the width of the central region in the transversal direction is less than the width of each of the side regions in the transversal direction, at least in the front section and the rear section, and the channel regions are of less basis weight than the side regions and the central region.

Absorbent article
(Object) To prevent leakage of body fluids and to readily transmit pressure from both sides to a center portion in a width direction by bringing an absorbent article into close contact with a crotch area extending from a body fluid discharge portion to a start position of the intergluteal cleft. (Means of Achieving the Object) A pair of right and left compressed grooves (8, 8) that extend in an approximately longitudinal direction is formed on a surface of a liquid permeable top sheet (3). The compressed grooves (8) have separation distance reduced regions (11), in which a separation distance between the right and left compressed grooves is reduced, formed at the back of a region corresponding to a body fluid discharge portion (H) of a wearer, and also have vastly enlarged portions (10), in which widths of the compressed grooves (8) are enlarged, formed at positions within the separation distance reduced regions (11) and where the separation distance between the right and left compressed grooves (8, 8) becomes minimum.

Absorbent article
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.
