Claims26
An absorbent article, which generally delimits a front waistband section, a rear waistband section and an intermediate section which interconnects said front and rear waistband sections, the article comprising:
- a substantially vapor-impermeable backsheet layer having a length;
- a liquid-permeable topsheet layer positioned in facing relation with said backsheet layer;
- an absorbent body located between said backsheet layer and said topsheet layer and having a length which is less than the length of said backsheet layer, said absorbent body overlaying at least a portion of said backsheet layer;
- a humidity transfer area formed by positioning said absorbent body such that an area of at least about 5.0 square centimeters of said backsheet in at least one waistband section of said article is not overlaid by said absorbent body and forming a vapor-permeable panel in said area of said backsheet, which vapor-permeable panel is substantially liquid impermeable, has a water vapor transmission rate value of at least about 2500 g/sq.m/24 hr. and an area of at least about 5.0 square centimeters;
- and
- a humidity transfer material located between said topsheet layer and said backsheet layer and having a wet compression recovery of at least about 74 percent, said humidity transfer material overlaying said humidity transfer area and extending over said absorbent body and into said intermediate section of said article.
