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.
Claims15
A wearable absorbent article comprising:
- a liquid pervious topsheet, said topsheet having an outward-facing topsheet surface and a wearer-facing topsheet surface, wherein the topsheet has been rendered hydrophobic via melt additive or surface treatment applied in a pattern;
- a backsheet joined to said topsheet, said backsheet having a wearer-facing backsheet surface and an outward-facing backsheet surface;
- and
- an absorbent core disposed between said topsheet and said backsheet, said absorbent core having a wearer-facing core surface and an outward-facing core surface;
- wherein a hydrophilic surfactant is applied over the pattern of the topsheet previously rendered hydrophobic.
A wearable absorbent article comprising:
- a liquid pervious topsheet, said topsheet having an outward-facing topsheet surface and a wearer-facing topsheet surface, wherein the topsheet has been rendered hydrophobic via melt additive or surface treatment applied in one or more stripes;
- a backsheet joined to said topsheet, said backsheet having a wearer-facing backsheet surface and an outward-facing backsheet surface;
- and
- an absorbent core disposed between said topsheet and said backsheet, said absorbent core having a wearer-facing core surface and an outward-facing core surface;
- wherein a hydrophilic surfactant is applied over the one or more stripes of the topsheet previously rendered hydrophobic.
A wearable absorbent article comprising:
- a liquid pervious topsheet, said topsheet having an outward-facing topsheet surface and a wearer-facing topsheet surface, wherein the topsheet has been rendered hydrophobic via melt additive or surface treatment applied in one or more areas;
- a backsheet joined to said topsheet, said backsheet having a wearer-facing backsheet surface and an outward-facing backsheet surface;
- and
- an absorbent core disposed between said topsheet and said backsheet, said absorbent core having a wearer-facing core surface and an outward-facing core surface;
- wherein a hydrophilic surfactant is applied over the one or more areas of the topsheet previously rendered hydrophobic.
