Abstract
An absorbent article including a liquid-permeable top layer, an absorbent core layer, a breathable outer cover, and a creped inner nonwoven fibrous layer between the absorbent core and breathable outer cover. The creped inner nonwoven fibrous layer has a level of creping of about 5-75%, and is preferably permanently creped. The creped inner nonwoven fibrous layer serves as a dampness inhibitor which reduces or prevents perceived dampness on the external surface of the outer cover by lowering thermal conductivity between the absorbent core and the outer cover surface.
Claims43
An absorbent article, comprising:
- a liquid-permeable top layer;
- an absorbent core layer;
- an inner nonwoven fibrous web;
- and
- a breathable, outer cover having a WVTR of at least about 300 grams/m2−24 hours;
- the breathable, liquid-impermeable outer cover positioned such that the inner nonwoven fibrous web is between the absorbent core layer and outer cover;
- wherein the inner nonwoven fibrous web has been creped to cause regions of out-of-plane bending.
An absorbent article, comprising:
- a liquid-permeable top layer;
- an absorbent core layer;
- a dampness-inhibiting inner nonwoven fibrous web having a level of creping of about 5-75%;
- and
- a breathable, liquid-impermeable outer cover having a WVTR of at least about 300 grams/m2−24 hours;
- the breathable outer cover positioned such that the inner nonwoven fibrous web is between the absorbent core layer and breathable outer cover;
- the outer cover including a breathable film facing the inner nonwoven fibrous web and an outer nonwoven fibrous web facing away from the inner nonwoven fibrous web.
An absorbent article, comprising:
- a liquid-permeable top layer;
- an absorbent core layer;
- a dampness-inhibiting inner nonwoven fibrous web having a basis weight of about 0.1-4.0 osy and a level of creping of about 5-75%;
- a breathable, liquid-impermeable outer cover including a breathable microporous film facing the inner nonwoven fibrous web, and an outer nonwoven fibrous web facing away from the inner nonwoven fibrous web;
- wherein the inner nonwoven fibrous web comprises hollow fibers and is positioned between the absorbent core layer and the breathable outer cover.
