Title (EN) ABSORBENT ARTICLE CONTAINING NANOPOROUS SUPERABSORBENT PARTICLES
(FR) ARTICLE ABSORBANT CONTENANT DES PARTICULES SUPERABSORBANTES NANOPOREUSES
Abstract:
(EN) An absorbent article includes an absorbent member positioned between a topsheet and a backsheet. The absorbent member contains at least one layer that includes superabsorbent particles containing a porous network that includes a plurality of nanopores having an average cross-sectional dimension of from about 10 to about 500 nanometers, wherein the superabsorbent particles exhibit a Vortex Time of about 80 seconds or less and a free swell gel bed permeability (GBP) of 5 darcys or more, of 10 darcys or more, of 60 darcys or more, or of 90 darcys or more.
(FR) L'invention concerne un article absorbant comprenant un élément absorbant positionné entre une feuille supérieure et une feuille arrière. L'élément absorbant contient au moins une couche qui comprend des particules superabsorbantes contenant un réseau poreux qui comprend une pluralité de nanopores ayant une dimension de section transversale moyenne d'environ 10 à environ 500 nanomètres, les particules superabsorbantes présentant un temps de Tourbillon d'environ 80 secondes ou moins et une perméabilité à travers un lit de gel (GBP) à gonflement libre de 5 darcys ou plus, de 10 darcys ou plus, de 60 darcys ou plus, ou de 90 darcys ou plus.
