Abstract
An absorbent article having a liquid pervious topsheet wherein at least a portion of the topsheet has been treated to become hydrophobic; a backsheet joined to said topsheet; an absorbent core disposed between said topsheet and said backsheet, said absorbent core having an inner surface oriented toward the skin of the wearer when said absorbent article is being worn and an outer surface oriented toward the garment of the wearer when said absorbent article is being worn; and a surfactant applied to at least a portion of said outer surface of said topsheet wherein the topsheet has been treated hydrophobic and wherein the hydrophilic surfactant is added to the areas treated hydrophobic.

An absorbent article comprising:
- a liquid pervious topsheet, said topsheet having an inner surface oriented toward the interior of said absorbent article and an outer surface oriented toward the skin of the wearer when said absorbent article is being worn wherein at least a portion of the topsheet has been treated to become hydrophobic,
- a backsheet joined to said topsheet, said backsheet having an inner surface oriented toward the interior of said absorbent article and an outer surface oriented toward the garment of the wearer when said absorbent article is being worn;
- an absorbent core disposed between said topsheet and said backsheet, said absorbent core having an inner surface oriented toward the skin of the wearer when said absorbent article is being worn and an outer surface oriented toward the garment of the wearer when said absorbent article is being worn;
- and
- a surfactant applied to at least a portion of said outer surface of said topsheet wherein the topsheet has been treated hydrophobic and wherein the hydrophilic surfactant is added to the areas treated hydrophobic.
A method of limiting surfactant migration on a topsheet, the method comprising:
- providing a nonwoven comprising a hydrophobic coating treatment or comprising a hydrophobic melt additive;
- and
- treating the portions of the topsheet treated with the hydrophobic coating treatment or the hydrophobic melt additive with a surfactant.
