摘要： An absorbent resin composition which shows high speed of absorption, excels in fluid permeability, and enjoys a high absorption capacity under load comprises primary particles of an absorbent resin and granulated particles of an absorbent resin having an average particle size smaller than the average particle size of the primary particles. An absorbent article contains the composition. The absorbent resin composition is produced by a method which comprises a step of producing granulated particles by granulating particles of absorbent resin having an average particle size in the range of 10 to 100 .mu.m and a step of mixing the resultant granulated particles of the absorbent resin with the primary particles of an absorbent resin having an average particle size in the range of 150 to 800 .mu.m. The granulated particles of an absorbent resin is produced by a method which comprises mixing the particles of absorbent resin with a granulating agent and extruding the resultant mixture through an extrusion granulating device provided with a spherical perforated plate.

摘要： The present invention provides a hydrophilicity-restoring agent for removing inorganic matter from a hydrophilic surface whose hydrophilicity has been reduced by the adhesion of the inorganic matter to thereby restore the hydrophilicity of the hydrophilic surface, and provides a method for restoring the hydrophilicity of a hydrophilic surface using the hydrophilicity-restoring agent. A gel of a hydrophilicity-restoring agent is prepared by mixing a thickener such as polyethylene glycol and xanthan gum with an aqueous solution in which a ligand such as citric acid to form a chelate complex is dissolved. The hydrophilicity of the hydrophilic surface is restored by applying the hydrophilicity-restoring agent to the hydrophilic surface with a reduced hydrophilicity and removing the hydrophilicity-restoring agent after an appropriate lapse of time.
