Abstract
A water-absorbing resin which has a specific surface area, as measured by the BET multipoint adsorption method employing krypton as an adsorbate gas, of 0.05 m2/g or larger and a water retentivity, as measured with 0.9 wt. % physiological saline, of 5 to 30 g/g. It is suitable for absorbing viscous liquids containing a high-molecular compound.
Claims5
A water-absorbent resin suitable for absorbing polymer-containing viscous liquids, wherein the resin has a specific surface area of no less than 0.05 m2/g measured by a BET multipoint technique using krypton gas as an adsorption gas;
- and
- wherein the resin has a water retention capacity of 5-30 g/g for 0.9 wt % physiological saline.
An absorbent core comprising a combination of a water-absorbent resin and a fibrous product,
- wherein the water-absorbent resin has a specific surface area of no less than 0.05 m2/g measured by a BET multipoint technique using krypton gas as an adsorption gas;
- and
- wherein the water-absorbent resin has a water retention capacity of 5-30 g/g for 0.9 wt % physiological saline.
An absorbent article comprising a liquid-permeable sheet, a liquid-impermeable sheet, and an absorbent core disposed therebetween;
- wherein the absorbent core comprises a combination of a water-absorbent resin and a fibrous product;
- wherein the water-absorbent resin has a specific surface area of no less than 0.05 m2/g measured by a BET multipoint technique using krypton gas as an adsorption gas;
- and
- wherein the water-absorbent resin has a water retention capacity of 5-30 g/g for 0.9 wt % physiological saline.
