Beschreibung
Zusammenfassung:	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. La présente invention concerne un composite absorbant qui inclut une matrice fibreuse insoluble dans l'eau, une composition polymère superabsorbante qui a un pouvoir d'absorption initial d'au moins environ 5 grammes de solution saline par gramme de composition polymère superabsorbante ; et un premier mécanisme déclencheur ayant un premier temps de libération compris entre environ 5 et 60 minutes, ladite composition superabsorbante ayant un second pouvoir d'absorption qui est environ 25 % supérieur au premier pouvoir d'absorption telle que mesuré par le test de capacité de rétention après centrifugation.
