Abstract
An absorbent composite 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, where the superabsorbent polymer composition has a second absorbent capacity that is at least about 25 % greater than the first absorbent capacity as measured by the mCRC Test.
Claims12
An absorbent composition comprising:
- a superabsorbent polymer composition having an initial absorbent capacity of at least about 5 grams saline per gram of superabsorbent polymer composition;
- and
- a first triggering mechanism having a first release time of between about 5 and 60 minutes;
- 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;
- a second triggering mechanism having a second release time of between about 10 and 120 minutes and at least about 5 minutes longer than the first release time;
- wherein the superabsorbent polymer composition has a third absorbent capacity of at least about 25% greater than the second absorbent capacity as measured by the mCRC Test.
