Abstract
There is provided a water-absorptive composite comprising a fibrous substrate bearing water-absorptive polymer particles. A process for producing the water-absorptive composite comprises the steps of: allowing an aqueous monomer solution containing a polymerizable monomer capable of providing a water-absorptive polymer to initiate polymerization by the use of a redox polymerization initiator; applying the resultant reaction mixture, which is in the course of polymerization, dropwise onto a fibrous substrate; and allowing the polymerization to proceed and finish on the substrate.
