摘要： Absorbent laminates and multi-layer, folded absorbent cores comprising the absorbent laminates for use in absorbent articles are presented. Specifically, multi-layer, folded absorbent cores are presented that are formed from an absorbent laminate comprising an absorbent layer between two tissue layers, in which the absorbent core includes a central channel running longitudinally along the core and crenellations profiled along the thickness of the core and providing enhanced liquid distribution across the core surface area or profile and improved liquid absorption into the laminate.

摘要： The present invention addresses the problem of providing an absorbent article in which a bonding part for bonding a liquid-permeable layer to an absorbent core has been formed in a low-basis-weight region of the absorbent core and which has all of sufficient flexural rigidity of the bonding part, sufficient bonding strength of the bonding part, and sufficient liquid-absorbing properties. This problem is solved with an absorbent core which comprises a first region that has a given absorbent-material basis weight and second regions (regions 411a, 411b) that have a lower absorbent-material basis weight than the first region, wherein the ratio of the basis weight of a highly absorbing polymer to the basis weight of the absorbent material in the second regions is regulated to 10/100 to 47/100, and compressed parts are formed inside the second regions.

摘要： A water-absorbent sheet structure (10) including a structure in which an absorbent layer (13) containing a water-absorbent resin (12) and an adhesive (11) is sandwiched with nonwoven fabrics from an upper side and a lower side of the absorbent layer, the water-absorbent sheet structure (10) comprising (1) an upper nonwoven fabric (14) which is a water-permeable nonwoven fabric having a water permeation rate of 10 s or less; and (2) a lower nonwoven fabric (15) which is a water-retaining nonwoven fabric having an amount of water absorbed of 250 g/m2 or more. The water-absorbent sheet structure (10) of the present invention is thin and is capable of sufficiently exhibiting water-absorbent capacities such as fast liquid permeability, a small amount of liquid re-wet, and a small amount of liquid leakage. Therefore, the water-absorbent sheet structure (10) according to the present invention is used for an absorbent material, whereby hygienic materials which are thin and have excellent body fittability can be provided.

摘要： A disposable absorbent product includes a backsheet, a topsheet overlaying the backsheet, and a core disposed between the backsheet and topsheet for retaining fluid secreted by a wearer of the absorbent product. The core has a length dimension, a width dimension, and a thickness dimension orthogonal to the length and width dimensions. The core includes first and second fluid storage structures, with the first fluid storage structure at least partially surrounding the second fluid storage structure in the thickness dimension. The second fluid storage structure extends along a longitudinal axis and has a head portion, as well as a pair of leg portions, with the leg portions being longitudinally opposed the head portion. Each of the leg portions extends along a minor axis that defines, with the longitudinal axis, an acute included angle.
