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.
