Absorbent members useful in the containment of body fluids such as urine, that have at least one region containing hydrogel-forming absorbent polymer in a concentration of from about 60 to 100 % by weight and providing a gel- continuous fluid transportation zone when in a swollen state. This hydrogel- forming absorbent polymer has: (a) a Saline Flow Conductivity (SFC) value of at least about 30 x 10-7 cm3 sec/g; (b) a Performance under Pressure (PUP) capacity value of at least about 23 g/g under a confining pressure of 0.7 psi (5 kPa); and (c) a basis weight of at least about 10 gsm. In addition, the region where this hydrogel-forming absorbent polymer is present has, even when subjected to normal use conditions, sufficient wet integrity such that the gel- continuous zone substantially maintains its ability to acquire and transport body fluids through the gel-continuous zone.

Cette invention concerne des articles absorbants utilisés pour contenir des fluides corporels tels que de l'urine, comprenant au moins une zone contenant un polymère absorbant formant un hydrogel présent selon une concentration comprise entre environ 60 et 100 % en poids et formant une zone de transport de fluide continue à base de gel lorsqu'elle est gonflée. Ce polymère absorbant formant un hydrogel présente : (a) une valeur de conductivité de flux salin au moins égale à environ 30 x 10?-7¿ cm?3¿ sec/g; (b) une valeur de capacité de performance sous pression au moins égale à environ 23 g/g avec des conditions de pression de confinement de 0,7 psi (5 kla); et (c) un poids de base au moins égal à 10 gsm environ. En outre, la zone dans laquelle est présent ce polymère absorbant formant un hydrogel, présente, même lorsqu'elle est soumise à des conditions normales d'utilisation, une intégrité au mouillage suffisante pour que la zone continue à base de gel conserve sensiblement son aptitude à capter et à transporter les fluides corporels dans ladite zone continue à base de gel.
