Patent ID: 7521587

Claim:
An absorbent article comprising a substantially liquid pervious topsheet, a substantially liquid impervious backsheet and an absorbent core between said topsheet and said backsheet, wherein said topsheet comprises a nonwoven fabric, wherein said nonwoven fabric comprises a plurality of fibers; hydrophilic polymers chemically grafted to the surface of at least a part of said plurality of fibers, said hydrophilic polymers being chemically grafted to said fibers by way of reactive radicals formed from at least one of (i) a reaction between a monomer molecule and a radical polymerization initiator molecule and (ii) a reaction between the fiber surface and a radical polymerization initiator molecule, the amount of radical polymerization initiator molecules being less than 2 wt % of the monomer molecules; and agent molecules, the amount of radical polymerization initiator molecules being at least three times the amount of the agent molecules by weight, wherein said nonwoven has a liquid strike through time of less than 5 s for a fifth gush of liquid and wherein said nonwoven provides a surface tension measurement of at least 65 mN/m according to the Determination of Surface Tension method.
