Zusammenfassung:Absorbent articles having reduced outer cover dampness are provided and include a hydrophobic barrier layer positioned between an absorbent core and a breathable liquid impervious outer cover. The hydrophobic barrier layer, such as one or more layers of nonwoven webs, has a thickness of at least 0.03 cm and a hydrohead value of at least 18 millibars. The hydrophobic barrier layer does not significantly reduce the water-vapor transmission rate (WVTR) of the absorbent article when the absorbent core is dry yet significantly reduces the overall WVTR of the absorbent article once the absorbent core is wet. Thus, an absorbent article is provided having a WVTR that exceeds about 1500 grams/square meter 24 hours when dry and yet is less than 15,000 grams/square meter 24 hours when wet.
