摘要:
PROBLEM TO BE SOLVED: To provide an absorbent article which is superior in liquid-absorbing performance of a skin contact sheet.SOLUTION: A skin contact sheet included in an absorbent article comprises a laminated non-woven fabric 10 having a layered structure of multiple fiber layers 11, 12 and having a fusion part 13 where they are fusion-bonded each other and integrated. The fusion part 13 and a non-fusion part 14 are present in each of a first surface 10a and a second surface 10b of the laminated non-woven fabric 10. The non-fusion part 14 of the first surface 10a is lower in hydrophilicity as compared to the non-fusion part 14 of the second surface 10b. In the first surface 10a, the non-fusion part 14 is lower in the hydrophilicity as compared to the fusion part 13. When a unit area 15 of a planar view square shape of 10 mm square comprising the fusion part 13 is virtually provided in the first surface 10a, there are present a high hydrophilicity area 15A being the unit area where the surface hydrophilicity is relatively high and a low hydrophilicity area 15B being the unit area where the surface hydrophilicity is relatively low, in the first surface 10a.SELECTED DRAWING: Figure 6COPYRIGHT: (C)2020,JPO&INPIT【課題】肌当接シートの吸液性能に優れる吸収性物品を提供すること。【解決手段】吸収性物品が備える肌当接シートが、複数の繊維層11,12の積層構造を有し且つそれらが互いに融着して一体化している融着部13を有する、積層不織布10を含む。積層不織布10の第1面10a及び第2面10bそれぞれに、融着部13と非融着部14とが存在する。第1面10aの非融着部14は、第2面10bの非融着部14に比して親水度が低い。第1面10aにおいて、非融着部14は融着部13に比して親水度が低い。融着部13を含む10mm四方の平面視正方形形状の単位領域15を、第1面10aに仮想的に設けた場合、第1面10aに、表面親水度が相対的に高い単位領域である高親水度領域15Aと、表面親水度が相対的に低い単位領域である低親水度領域15Bとが存在する。【選択図】図6
