Absorbent article
In order to absorb a small amount of liquid, to prevent an absorbent article from being disintegrated by the absorbed liquid, and to prevent piping of a toilet from being clogged even if the absorbent article is flushed into a flush toilet, the absorbent article includes a pulp layer containing a crushed pulp or fibers mainly containing a crushed pulp, and the pulp layer has a water repellent surface layer portion formed by applying a water repellent agent to at least one surface layer portion.
1. An absorbent article, comprising:
a plurality of pulp layers each containing a crushed pulp or fibers mainly containing a crushed pulp, wherein
each of the pulp layers has a water repellent surface layer portion formed by applying a water repellent agent to at least one surface layer portion such that the water repellent surface layer portion has a non-uniform water repellent strength by the water repellent agent, and
the absorbent article has a skin surface and a non-skin surface opposite with respect to the skin surface.
2. The absorbent article according to claim 1 , further comprising:
a water-disintegrable sheet layer joined to the plurality of pulp layers.
3. The absorbent article according to claim 1 , wherein the water repellent agent is a silicon-based compound or a fluorine-based compound.
4. The absorbent article according to claim 1 , wherein the plurality of pulp layers is formed such that an amount of the applied water repellent agent increases from a pulp layer located on a skin surface side toward a pulp layer located on a non-skin surface side.
5. The absorbent article according to claim 1 , having an embossed shape on the skin surface.
6. The absorbent article according to claim 1 , wherein the water repellent surface layer portion is formed on a non-skin surface side of each of the pulp layers.
7. The absorbent article according to claim 1 , wherein
the plurality of pulp layers is pressed.
8. The absorbent article according to claim 7 , further comprising a water-disintegrable sheet layer joined to an outermost side of the plurality of pulp layers.
9. The absorbent article according to claim 8 , wherein the water-disintegrable sheet layer has a water repellent surface formed by applying a water repellent agent.
10. The absorbent article according to claim 8 , comprising a hole penetrating the water-disintegrable sheet layer and a part of the plurality of pulp layers.
11. The absorbent article according to claim 10 , wherein the absorbent article has a plurality of the holes formed at substantially regular intervals.
12. The absorbent article according to claim 10 , wherein the absorbent article has a plurality of the holes, and lengths of the holes are different from one another.
13. The absorbent article according to claim 1 , wherein the pulp layers are laminated in a direction from the skin surface to the non-skin surface, and the water repellent surface layer portion is formed on a skin surface side and/or a non-skin surface side of each of the pulp layers.
14. The absorbent article according to claim 1 , further comprising a water-disintegrable sheet layer joined to an outermost side of the plurality of pulp layers.
15. The absorbent article according to claim 14 , wherein the water-disintegrable sheet layer has a water repellent surface formed by applying a water repellent agent.
16. The absorbent article according to claim 14 , comprising a hole penetrating the water-disintegrable sheet layer and a part of the plurality of pulp layers.
17. The absorbent article according to claim 16 , wherein the absorbent article has a plurality of the holes formed at substantially regular intervals.
18. The absorbent article according to claim 16 , wherein the absorbent article has a plurality of the holes, and lengths of the holes are different from one another.
19. An absorbent article, comprising:
a plurality of pulp layers each containing a crushed pulp or fibers mainly containing a crushed pulp, wherein
each of the pulp layers has a water repellent surface layer portion formed by applying a water repellent agent to at least one surface layer portion,
the absorbent article has a skin surface and a non-skin surface opposite with respect to the skin surface, and
the plurality of pulp layers is formed such that an amount of the applied water repellent agent increases from a pulp layer located on a skin surface side toward a pulp layer located on a non-skin surface side.
20. The absorbent article according to claim 19 , wherein the water repellent surface layer portion has a non-uniform water repellent strength by the water repellent agent.
