发明名称 WATER-ABSORBENT SHEET COMPOSITION
摘要 A water-absorbent sheet composition containing a structure in which an absorbent layer containing a water-absorbent resin and an adhesive is sandwiched with two or more sheets of hydrophilic nonwoven fabrics, wherein the water-absorbent sheet composition has a structure in which the absorbent layer is separated in divided parts of a primary absorbent layer and a secondary absorbent layer with a water-permeable substrate having a water permeability index of from 20 to 90, and wherein the water-absorbent resin is contained in the absorbent layer in an amount of from 100 to 1000 g/m2. The water-absorbent sheet composition of the present invention exhibits some excellent effects that the water-absorbent sheet composition is capable of accomplishing thinning and avoidance of gel blocking phenomenon and liquid leakage, while obtaining basic properties as a water-absorbent sheet composition at a high level, even for a water-absorbent sheet composition containing a very small amount of pulps.
