Abstract
Provided is an absorbent article that has an excellent capability of quickly absorbing a large amount of urine and the like, while preventing loss of the absorbing polymers to the outside of the absorbent article where the absorbent article comprises a first nonwoven fabric and a second nonwoven fabric between which a water-absorbing polymer group is placed, in which the surface of the first nonwoven fabric on the side of the water-absorbing polymer group has openings.
Claims5
An absorbent article comprising a first nonwoven fabric and a second nonwoven fabric that sandwich a water-absorbing polymer group,
- wherein the surface of the first nonwoven fabric on the side of the water-absorbing polymer group has openings,
- wherein the 90% diameter in the diameter distribution of the openings is 10 μm or more and 130 μm or less,
- wherein the difference between the 90% diameter and the 10% diameter in the diameter distribution of the openings is 100 μm or less;
- wherein the surface of the first nonwoven fabric on the opposite side of the water-absorbing polymer group has openings,
- wherein the porosity of the openings is 25% or more and 50% or less;
- wherein the water holding rate of the first nonwoven fabric is 1000 mass % or more;
- wherein at least one surface of the second nonwoven fabric has openings,
- wherein the 90% diameter in the diameter distribution of the openings is 10 μm or more and 130 μm or less,
- wherein the difference between the 90% diameter and the 10% diameter in the diameter distribution of the openings is 100 μm or less;
- wherein the water-absorbing polymer constituting the water-absorbing polymer group is particulate;
- and
- wherein the particle diameter of the water-absorbing polymer is more than 106 μm and 1000 μm or less.
