Absorbent articles having substrates having zonal treatments

A diaper or a pant comprising:

• a liquid permeable topsheet;
• a liquid impermeable backsheet;
• a laterally-extending structural separator extending upwardly relative to a portion of the topsheet and defining a front region on a first side of the structural separator and a back region on a second side of the structural separator, wherein the laterally-extending structural separator crosses a central longitudinal axis of the absorbent article;
• an absorbent core positioned at least partially intermediate the liquid permeable topsheet and the liquid impermeable backsheet, wherein the absorbent core comprises an absorbent material, and wherein the absorbent material defines a first channel therethrough;
• and
• a liquid management system positioned at least partially intermediate the liquid permeable topsheet and the absorbent core, wherein the liquid management system defines a second channel therethrough;
• wherein the liquid permeable topsheet comprises a first zone situated primarily in the front region and having a first substantially transferrable chemical treatment that is hydrophobic and a second zone situated primarily in the back region and having a second substantially transferrable chemical treatment that has a different hydrophilicity as the first chemical treatment.

An absorbent article comprising:

• a liquid permeable topsheet;
• a liquid impermeable backsheet;
• a central lateral axis defining a front region on a first side of the central lateral axis and a back region on a second side of the central lateral axis;
• a laterally-extending structural separator extending upwardly relative to a portion of the topsheet and defining the front region on a first side of the structural separator and the back region on a second side of the structural separator, wherein the laterally-extending structural separator crosses a central longitudinal axis of the absorbent article;
• and
• an absorbent core positioned at least partially intermediate the liquid permeable topsheet and the liquid impermeable backsheet, wherein the absorbent core comprises an absorbent material, wherein the absorbent material defines a channel therethrough, and wherein the channel crosses the central lateral axis, but is free of intersection with the central longitudinal axis;
• a liquid management system positioned at least partially intermediate the liquid permeable topsheet and the absorbent core, wherein the liquid management system defines a second channel therethrough;
• wherein the liquid permeable topsheet comprises a first zone situated primarily in the front region and having a first substantially transferrable chemical treatment and a second zone situated primarily in the back region and having a second substantially transferrable chemical treatment, wherein a basis weight of the second substantially transferrable chemical treatment is greater in the second zone than the basis weight of the first substantially transferrable chemical treatment in the first zone, and wherein the first substantially transferrable chemical treatment has a different composition than the second substantially transferrable chemical treatment.
