Title: (EN) CORE ASSEMBLIES FOR ABSORBING LIQUIDS AND ABSORBENT PRODUCTS INCLUDING THE SAME
(FR) ENSEMBLES NOYAUX DESTINES A ABSORBER DES LIQUIDES ET PRODUITS ABSORBANTS UTILISANT LESDITS ENSEMBLES NOYAUX
Abstract: front page image
(EN) An absorbent core assembly for use in a product for absorbing a liquid is disclosed. The core assembly has a first section and a second section. The first section is a quilted porous material that contains a slow acting but high absorption capacity SAP therein. The, second section is a quilted porous material that contains a fast acting but lower absorption capacity SAP therein. The first and second sections are in fluid communication with each other, whereupon a liquid which is exposed to the core assembly flows through the first section to the fast acting SAP in the second section to be absorbed quickly and rapidly by the fast acting SAP therein, while the slow acting SAP desorbs or takes liquid away from the fast acting SAP as well as absorbing the liquid itself to thereby trap the liquid in the core assembly.
