An adsorbent pad including an elongated core positioned substantially in the center of the pad, wherein the core protrudes out of the top surface of the pad. The adsorbent pad helps to direct the flow of fluids such as urine and blood to the elongated core, so that the wearer of the pad experiences less leakage of fluids to help with leaks better coverage throughout the use of the pad.

A disposable absorbent pant having a belt structure that encircles the wearer's waist, with front and rear belt portions, and a longitudinally channeled absorbent core structure, is disclosed. The channels are extended so as to underlie at least one of the front and rear belt portions, thereby providing added structural support to restrain the absorbent core and reduce the likelihood of undesirable bulging in the front and/or rear of the pant while it is worn, after the core has absorbed liquid and stiffened longitudinally as a result of the channeled structure.

An absorbent article has an absorbent body obtained by mixing and accumulating fibers and high absorbent polymer particles. A wrapping sheet includes an intermediate part located on a front face side of the absorbent body and both side parts folded back to a back face side of the absorbent body from the intermediate part. Distal ends of the both side parts of the wrapping sheet are overlapped on the back face side of the absorbent body to form a connecting portion. A total weight of the high absorbent polymer particles is larger than a total weight of the fibers in the absorbent body. A content rate of the high absorbent polymer particles of the absorbent body increases stepwise or continuously from the back face side toward the front face side.

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.

Disposable absorbent diapers are provided with improved comfort, fit and liquid transportation. The absorbent core of the disposable absorbent diapers includes at least one absorbent structure having a substrate layer and an absorbent layer with channels.

In an absorbent article (200), a pair of slits (40) each extending in a front and rear direction with a predetermined width is formed in an absorbent body (23) at a front and rear direction region at least at a crotch portion (C2) such that to section a first portion (11) at middle, and a second portion (12) and a third portion (12) at both sides of the first portion in a width direction, respectively, projection portions (23P) projected toward both sides in the width direction at middle in the front and rear direction of the first portion (11) are included in the absorbent body, and cavity portions (23D) in which the projection portions (23P) fit outwardly in the width direction are formed at a front and rear direction position corresponding to the projection portions (23P) in the second portion (12) and the third portion (12), respectively.

A disposable absorbent pant having a belt structure that encircles the wearer's waist, with front and rear belt portions, and a longitudinally channeled absorbent core structure, is disclosed. The channels are extended so as to underlie at least one of the front and rear belt portions, thereby providing added structural support to restrain the absorbent core and reduce the likelihood of undesirable bulging in the front and/or rear of the pant while it is worn, after the core has absorbed liquid and stiffened longitudinally as a result of the channeled structure.

A method for forming an absorbent pad including a first layer, a second layer and an absorbent material interposed between the first and the second layer and arranged according to a spreading pattern M1 having at least one channel which is free of absorbent material, includes a step of feeding a first web, intended to form the first layer of the pad; a step of feeding a second web, intended to form the second layer of the pad; a step of spreading the absorbent material on the first web according to the spreading pattern M1; a step of joining the first and second webs, a step of removing any absorbent material that may be present in the channel.

A process for producing water-absorbing polymer particles by suspension polymerization and thermal surface postcrosslinking, wherein the base polymer obtained by suspension polymerization has a centrifuge retention capacity of at least 37 g/g and the thermal surface postcrosslinking is conducted at 100 to 190 C.

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.
