An absorbent article comprising a liquid permeable topsheet, a backsheet, an absorbent core comprising an absorbent material and a core wrap is provided. The core comprises at least one channel-forming area that is substantially free of absorbent material. The absorbent article comprises a masking layer between the bottom side of the core wrap and the backsheet. The masking layer and the bottom side of the core wrap are only partially bonded to each other at their interface, the interface thus comprising a bonded portion and an unbonded portion, wherein the channel-forming area at least partially corresponds to the unbonded portion of the interface, so that when the absorbent material swells, the masking layer can decouple from the three-dimensional channels.

An absorbent core with an efficient flow guide property and breathability, and method for manufacturing same. The absorbent core comprises a surface layer, a bottom layer, and an absorbent layer between the surface layer and the bottom layer; the absorbent layer comprises a non-woven fabric layer attached to the lower surface of the surface layer; a super absorbent polymer is uniformly scattered in the non-woven fabric layer; the surface layer and the non-woven fabric layer are attached to each other to form a composite layer; a flow guide groove is formed on the composite layer and divides the absorbent core into a plurality of absorbent regions; the composite layer with the flow guide groove is connected with the upper surface of the bottom layer; a super absorbent polymer is uniformly scattered between the bottom surface of the non-woven fabric layer and the upper surface of the bottom layer.

An absorber includes a concave groove-shaped body fluid inflow portion along a longitudinal direction of an incontinence pad and over a range in the longitudinal direction including a body fluid discharge portion of a wearer, and a granular powder superabsorbent resin is arranged at least on a side edge portion of the absorber and over the range in the longitudinal direction including the body fluid inflow portion. Since the body fluid flowing into the body fluid inflow portion is diffused and is absorbed and held in the superabsorbent resin on the side edge portion of the absorber, it is possible to provide an adequate absorbed amount in the absorber despite the concave groove in the absorber. Even when the superabsorbent resin becomes swollen with absorbed body fluid, the body fluid inflow portion is not blocked, with the result that the absorption speed is not reduced.

An absorbent article has a length direction, a width direction and a thickness direction, and is provided at least with an absorbent body including water-absorbent fibers. The absorbent body includes deformation-guiding portions which extend in a predetermined direction, and base portions provided on both sides of each deformation-guiding portion. The deformation-guiding portions are provided with compressed regions which extend in said predetermined direction and in which the absorbent body has been compacted in the thickness direction, and protruding portions which extend in the predetermined direction on both sides of each compressed region and which protrude from the base portion toward the skin surface. The configuration is such that the fiber density of the protruding portions is less than the fiber density of the base portion.

The purpose of the present invention is to provide a method for manufacture of an absorbent article, with which it is possible to form a desired coloring pattern upon an absorbent article and to reliably manage the quality of said coloring pattern. Provided is a method for manufacture of an absorbent article, in which: microcapsules, which are provided upon a substrate and in which coloring agents are enclosed, are destroyed in a prescribed pattern, and the coloring agents discharged upon the substrate; and the substrate is coated with a developer, causing the coloring to be expressed in the prescribed pattern via a reaction between the coloring agents and the developer.

An absorbent article comprising an absorbent core sandwiched between a liquid permeable topsheet and a liquid impermeable backsheet, and an acquisition distribution layer 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 core comprises 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 layer comprises a spunbond and/or carded nonwoven layer comprising synthetic fibers, wherein said synthetic fibers are comprised at a level of greater than 80% wt by weight of said acquisition distribution layer, and wherein said acquisition distribution layer has a basis weight of from 10 to 50 g/m.sup.2.

Provided is an absorbent article which exhibits a better permeation rate and in which occurrence of leakage is suppressed. An absorbent article comprising: a liquid-permeable front surface sheet; a liquid-impermeable back surface sheet; and an absorbent body disposed between the front and back surface sheets, wherein the absorbent body contains a water-absorbent resin, and the water-absorbent resin has properties (A)-(C). (A) The amount of saline that can be retained is 45-70 g/g. (B) The amount of saline that can be absorbed under a load of 4.14 kPa is at least 13 ml/g. (C) The five-minute value of no-pressure DW is 50-80 ml/g.

An absorbent article for personal hygiene having a front edge and a back edge and comprising a liquid impermeable backsheet, a liquid permeable topsheet, an absorbent core and a pair of barrier leg cuffs disposed symmetrically relative to the longitudinal axis. Each barrier leg cuff is defined by a proximal edge attached to the rest of the article and an elasticized terminal edge that can protrude upwards. The topsheet comprises a raisable region that is attached to the barrier leg cuffs so that when the barrier leg cuffs are raised, the raisable region is lifted up by the barrier leg cuffs and an empty volume is formed between the raisable region and the chassis of the article underneath.

An absorbent article for wearing about the lower torso of a wearer includes a topsheet, a backsheet joined to at least a portion of the topsheet, and an absorbent core disposed between the topsheet and the backsheet. The absorbent core includes a first layer and a second layer, wherein the first layer is disposed in fluid communication with the second layer. The first layer has a first shape and the second layer has a second shape. The first shape is different from the second shape. Each of the first layer and second layer comprise less than about 20 percent airfelt.

A sheet-like article (1) for an absorbent article of the invention includes a plurality of absorbent units (4), each including: a long base portion (2); and water-absorbent polymer particles (3) that are fixed to a surface of first side of the long base portion (2). In the sheet-like article (1), the absorbent units (4) are arranged such that the longitudinal direction thereof is oriented in one direction. When the water-absorbent polymer particles (3) absorb a liquid, the water-absorbent polymer particles (3) swell beyond the lateral side edge portions (2s), of the long base portion (2), that extend along the longitudinal direction, and a position, in the thickness direction, of each long base portion is varied from the position thereof before absorbing the liquid.
