<p>An absorbent article, e.g. diaper, comprises a non-woven fabric containing fibers. The non-woven fabric has a surface tension of >=65 mN/m when wetted with saline solution and a liquid strike through time not less than5 seconds for a fifth gush of liquid; and polymers of hydrophilic monomer molecules and radical polymerization initiator molecules, which are up to 2 (preferably up to 1) wt.% of the monomer molecules. An absorbent article, e.g. diaper (20), comprises liquid pervious top sheet (24), liquid impervious back sheet (26), and an absorbent core (28) between the top sheet and back sheet. The absorbent article comprises a nonwoven fabric containing fibers and polymers. The nonwoven fabric has a surface tension of >=65 mN/m when being wetted with saline solution and a liquid strike through time of less than 5 second for a fifth gush of liquid. The polymers comprise hydrophilic monomer molecules and radical polymerization initiator molecules chemically grafted to the surface of fibers comprised by the nonwoven fabric. The amount of radical polymerization initiator molecules is up to 2 (preferably up to 1) wt.% of the monomer molecules. Independent claims are also included for: (a) a process for treating fibers for making an absorbent article comprising providing fibers and an aqueous solution having hydrophilic monomers and radical polymerization initiators, contacting the fibers with the aqueous solution, exposing the fibers to UV radiation for up to 2 seconds; and (b) a process for making an absorbent article.</p> |
