There is provided a process for preparing a water absorptive fibrous material, which comprises the combination of the following steps of: (A) applying an aqueous solution of a polymerizable monomer comprising as a main component acrylic acid, of which 20% or more of the carboxyl groups have been neutralized to its alkali metal salt or ammonium salt, to a prefabricated fibrous substrate; (B) polymerizing the polymerizable monomers applied to said fibrous substrate and (C) adding to said so treated material a crosslinking agent having two or more functional groups reactive with the carboxyl groups and/or carboxylate groups contained in the polymer to react therewith. p |
