Abstract
An absorbent article has an absorbent composite that includes a water-insoluble fibrous matrix, a superabsorbent polymer composition that has an initial absorbent capacity of at least about 5 grams of saline per gram of superabsorbent polymer composition; and a first triggering mechanism having a first release time of between about 5 and 60 minutes, and a second triggering mechanism. The superabsorbent polymer composition may have a second absorbent capacity that is at least about 25% greater than the first absorbent capacity as measured by the mCRC Test.
Claims15
An absorbent article comprising:
- an absorbent core comprising a superabsorbent polymer composition having an initial absorbent capacity of at least about 5 grams saline per gram of superabsorbent polymer composition;
- a first triggering mechanism having a first release time of between about 5 and 60 minutes;
- and
- a second triggering mechanism having a second release time that is different than the first release time;
- wherein the superabsorbent polymer composition has a second absorbent capacity of at least about 25% greater than the first absorbent capacity as measured by the mCRC Test.
The absorbent article of claim 11 wherein the absorbent core comprises about 60% to about 95% by weight of the superabsorbent polymer composition.
