摘要： The problem is to attain, in a crotch part, both a fitting property of an absorbent element and shape maintainability of an absorber. The above problem is solved by a disposable diaper including an absorber element 50, which is provided in a range in a front-back direction LD including a crotch part M, and includes an absorbent 56 and a wrapping sheet 58 wrapping the absorber 56, wherein the absorber 56 is formed by accumulating a mixture of pulp fibers and super absorbent polymer particles, in the crotch part M, the absorber 56 has elongated low-basis weight sections 56L, which extend in the front-back direction LD on both sides thereof in a width direction WD, compressed portions 51, which are compressed in a thickness direction so as to be depressed from a surface into the absorber, are continuous in lattice shaped patterns provided across at least entire regions SR being lateral to the low-basis weight sections 56L in the absorbent element 50, and the wrapping sheet 58 is made of a nonwoven fabric having a bending resistance of 0.01 to 0.10 mN·cm in the front-back direction LD and 0.01 to 0.10 mN·cm in the width direction WD according to 41.5° Cantilever Method defined by JIS L 1913: 2010.

摘要： The current invention concerns an absorbent article (10) comprising an absorbent core (12) sandwiched between a liquid permeable topsheet (14) and a liquid impermeable backsheet (16), and an acquisition distribution layer (18) arranged between said topsheet (14) and said absorbent core (12), wherein the absorbent core (12) comprises at least an absorbent material layer. According to the invention the topsheet (14) consists essentially of an air-through bonded nonwoven layer and the acquisition distribution layer (18) consists essentially of a spunbonded and/or carded nonwoven layer and the absorbent core (12) comprises at least one channel (26) free of absorbent material. The invention also relates to the use of an absorbent article (10) comprising a topsheet (14) consisting essentially of an air-through bonded nonwoven layer, an acquisition distribution layer (18) consisting essentially of a spunbonded and/or carded nonwoven layer and an absorbent core (12) comprising at least one channel (26) free of absorbent material, for managing liquid stool.

摘要： To achieve both of absorbability of a viscous liquid and absorption performance of a non-viscous liquid. The above problem is solved by a configuration in which an upper auxiliary layer 71 of an absorber 70 includes a super absorbent nonwoven fabric 42 having a surface exposed on an uppermost surface of the absorber 70 and having a Klemm water absorptiveness of 100 mm or more, first super absorbent polymer particles 43 adjacent to a back surface of the super absorbent nonwoven fabric 42, the main absorption layer 72 of the absorber 70 is a cell absorbing sheet 50 including second super absorbent polymer particles 53 contained in the cells 55 arranged at intervals, a convex 50p bulging upward is formed in a portion located at each cell 55 in an upper sheet 51, the first super absorbent polymer particles 43 are fixed to the upper surface of the upper sheet 51 of the main absorption layer 72, and an adhesion amount of the first super absorbent polymer particles 43 on the upper surface of the upper sheet 51 increases from the top of a convex 50p toward the bottom of a valley located between a convex 50p and a convex 50P adjacent each other.
