An absorbent member for use in disposable diapers, wherein the absorbent member comprises a modified water absorbent resin. The modified water absorbent resin is made according to the method which comprises a) mixing a water absorbent resin and a water-soluble radical polymerization initiator or a heat-degradable radical polymerization initiator without addition of an ethylenically unsaturated monomer and b) irradiating the resultant mixture with active energy rays. The method is particularly capable of exalting the absorbency against pressure and the saline flow conductivity.
L'invention concerne un élément absorbant destiné à être utilisé dans des couches jetables, l'élément absorbant renfermant une résine hydrophile modifiée. La résine hydrophile modifiée est fabriquée selon le procédé qui consiste à: a) mélanger une résine hydrophile et un initiateur de polymérisation radical thermodégradable sans l'addition d'un monomère éthylénique insaturé et b) à irradier le mélange obtenu avec des rayons énergétiques actifs. Ce procédé convient particulièrement pour renforcer le pouvoir absorbant contre la pression ainsi que pour renforcer la conductivité au flux salin.
