摘要:
Provided is an absorbent article that efficiently increases the volume of excreta that can be absorbed and held. The liquid-absorbing pad (1) has a skin-facing surface and a non-skin-facing surface and is equipped with a surface sheet (2) disposed on the skin-facing surface, a back sheet (3) disposed on the non-skin-facing surface, and a liquid-absorbing structure (10) that lies between the surface sheet (2) and the back sheet (3). The liquid-absorbing structure (10) comprises two superposed layers, a first and a second absorption layer (21, 41). The first absorption layer (21) is disposed on the skin-facing surface side, and has a particle-comprising region (24) where absorbent polymer particles are present and a particle-less region (25) where the absorbent polymer particles are substantially absent. The second absorption layer (41) is disposed on the non-skin-facing surface side, comprises hydrophilic fibers (19) and absorbent polymer particles, and is formed so as to have a high density region (44) where the density of hydrophilic fibers (19) is high and a low density region (45) where the density of hydrophilic fibers (19) is low. The first absorption layer (21) is layered on the second absorption layer (41) so that the particle-less region (25) and the low density region (45) overlap. The low density region (45) and the high density region (44) are connected via the hydrophilic fibers (19).Linvention concerne un article absorbant qui augmente efficacement le volume dexcrétas qui peut être absorbé et retenu. Le tampon (1) dabsorption de liquide a une surface tournée vers la peau et une surface non tournée vers la peau, et est doté dune feuille de surface (2) disposée sur la surface tournée vers la peau, dune feuille arrière (3) disposée sur la surface non tournée vers la peau, et dune structure (10) dabsorption de liquide qui sétend entre la feuille de surface (2) et la feuille arrière (3).
