Abstract

A body wiping sheet (1) comprising two surface layers (2, 3) each comprising a non-woven fabric, and a water-absorbent polymer layer that contains a water-absorbent polymer and that is disposed between the two surface layers (2, 3) in a stacked manner.

First claim

The invention claimed is:

1. A body wiping sheet comprising:
two surface layers each comprising a non-woven fabric; and
a water-absorbent polymer layer that contains a water-absorbent polymer and that is disposed between the two surface layers in a stacked manner;
wherein the body wiping sheet is a dr sheet that does not contain an aqueous cleaning agent.

2. The body wiping sheet according to claim 1 , wherein the water-absorbent polymer layer is a sheet containing a water-absorbent polymer incorporated into a fibrous material, a sheet containing a water-absorbent polymer dispersed and solidified on a fibrous material, or a sheet containing a water-absorbent polymer processed into a fibrous structure.

3. The body wiping sheet according to claim 1 , wherein the water-absorbent polymer layer contains the water-absorbent polymer in an amount capable of maintaining the temperature of the body wiping sheet at 30° C. or higher after the body wiping sheet is immersed in water for a duration of time to sufficiently swell the polymer, heated to 60° C., and then stored for 10 minutes in an environment at 20 to 25° C. at a humidity of 40 to 80%.

4. The body wiping sheet according to claim 1 , wherein the surface layers and the water-absorbent polymer layer are fixed at least at one point.

5. The body wiping sheet according to claim 4 , wherein the at least one fixing portion is substantially linear.

6. The body wiping sheet according to claim 5 , wherein the at least one substantially linear fixing portion extends from one end to the other end of the body wiping sheet.

7. The body wiping sheet according to claim 4 , wherein the body wiping sheet is substantially rectangular, and wherein the at least one fixing portion comprises two substantially linear fixing portions at least in one direction.

8. The body wiping sheet according to claim 4 , wherein the at least one fixing portion comprises two substantially linear fixing portions that are provided at both ends of the body wiping sheet and that are formed simultaneously when the two surface layers are joined to each other.

9. The body wiping sheet according to claim 4 , wherein the at least one fixing portion is a joined portion obtained by heat sealing.

10. The body wiping sheet according to claim 1 , wherein the water-absorbent polymer layer is separated into two portions by a depressed portion that extends substantially linearly in the longitudinal direction at the center of the width direction of the body wiping sheet.

11. The body wiping sheet according to claim 1 , wherein the body wiping sheet is substantially rectangular and further has two guiding lines extending along imaginary lines that extend apart from each other in the longitudinal direction of the body wiping sheet between a long side of the body wiping sheet and positions each located at the same distance from the center of the longitudinal direction of the body wiping sheet in the line extending in the longitudinal direction of the body wiping sheet at the center of the width direction of the body wiping sheet.

12. The body wiping sheet according to claim 1 , wherein the body wiping sheet further comprises a small piece that is attached to a corner of one of the two surface layers and that defines a pocket for accommodating the body wiping sheet between the piece and one of the surface layers.

13. A body wiping sheet comprising:
two surface layers each comprising a non-woven fabric; and
a water-absorbent polymer layer that contains a water-absorbent polymer and that is disposed between the two surface layers in a stacked manner;
wherein the body wiping contains water and does not contain an aqueous cleaning age.

14. The body wiping sheet according to claim 13 , wherein the water-absorbent polymer layer is a sheet containing a water-absorbent polymer incorporated into a fibrous material, a sheet containing a water-absorbent polymer dispersed and solidified on a fibrous material, or a sheet containing a water-absorbent polymer processed into a fibrous structure.

15. The body wiping sheet according to claim 13 , wherein the water-absorbent polymer layer contains the water-absorbent polymer in an amount capable of maintaining the temperature of the body wiping sheet at 30° C. or higher after the body wiping sheet is immersed in water for a duration of time to sufficiently swell the polymer, heated to 60° C., and then stored for 10 minutes in an environment at 20 to 25° C. at a humidity of 40 to 80%.

16. The body wiping sheet according to claim 13 , wherein the surface layers and the water-absorbent polymer layer are fixed at least at one point.

17. The body wiping sheet according to claim 13 , wherein the t least one fixing portion is substantially.

18. The body wiping sheet according to claim 13 , wherein the water-absorbent polymer layer is separated into two portions by a depressed portion that extends substantially linearly in the longitudinal direction at the center of the width direction of the body wiping sheet.

19. The body wiping sheet according to claim 13 , wherein the body wiping sheet further comprises a small piece that is attached to a corner of one of the two surface layers and that defines a pocket for accommodating the body wiping sheet between the piece and one of the surface layers.
