A water-absorbent sheet comprising a structure in which an absorbent layer containing a water-absorbent resin and an adhesive is sandwiched with nonwoven fabrics from an upper side and a lower side of the absorbent layer, wherein the water-absorbent sheet has a laminate structure in which the absorbent layer is fractionated into a primary absorbent layer and a secondary absorbent layer with a breathable fractionating layer, and wherein at least one sheet out of the nonwoven fabrics is a spunbond nonwoven fabric, and at least a nonwoven fabric at a lower side out of the nonwoven fabrics is a hydrophilic nonwoven fabric. The water-absorbent sheet of the present invention exhibits some effects that a water-absorbent sheet is capable of accomplishing avoidance of gel blocking phenomenon and liquid leakage, while obtaining basic properties as a water-absorbent sheet at a high level, by using specified nonwoven fabrics, and further providing a hydrophilic nonwoven fabric as a lower side of a nonwoven fabric of the absorbent layer of a water-absorbent sheet, even for a water-absorbent sheet containing a very small amount of pulps and being thinner than a conventional product.

Water absorbing sheet composite

A water absorbing sheet composite having a structure in which a water absorptive resin and a hot melt adhesive are sandwiched by two or more sheets of hydrophilic nonwoven fabric.  The hydrophilic nonwoven fabric has a basis weight of not less than 30 g/m 2 , the content of the water absorptive resin is 10 to 150 g/m 2 , and the content of the hot melt adhesive is 0.10 to 1.0 time the content (with reference to the mass) of the water absorptive resin.  Although thin, the water absorbing sheet composite does not deform before and after absorbing liquid and has ability of sufficiently absorbing not only a liquid having low viscosity but also a liquid having high viscosity.  The water absorbing sheet composite can be used as an absorbing body in applications such as a sanitary napkin and an incontinence pad to provide a hygienic material which is thin, has a good aesthetic external appearance, and does not cause an inconvenience such as liquid leakage.
