Claims20
An absorbent article, comprising:
- a. a topsheet;
- b. a backsheet;
- c. an absorbent core disposed between the topsheet and the backsheet, the absorbent core comprising a first substrate, a second substrate, and absorbent particulate polymer material arranged between the first substrate and the second substrate;
- and
- d. an acquisition layer disposed between the absorbent core and the topsheet;
- e. wherein the absorbent core comprises a longitudinally-extending cavity comprising a cavity volume;
- f. wherein the second substrate deflects into the cavity and is adhered to the first substrate within the cavity;
- g. wherein the cavity is substantially free of the absorbent particulate polymer material;
- h. wherein the cavity comprises a channel extending in a direction substantially parallel to a longitudinal axis of the absorbent article;
- and
- i. wherein the absorbent core exhibits a wet immobilization of more than 50% according to the Wet Immobilization Test described herein.
