Title (EN) ABSORBENT CORE HAVING TUBE-SHAPED SWELLING CHAMBER
(FR) ÂME ABSORBANTE À CHAMBRE DE DILATABLE EN FORME DE TUBE.
Abstract: front page image
(EN)An absorbent cores includes absorbent material enclosed a core wrap which comprises a liquid permeable substrate layer. The core contains from about 87% to about 100% of superabsorbent polymer and a tube-shaped swelling chamber having a length to width aspect ratio of less than or equal to about 5:1. The area of the core is at least twice the area of the swelling chamber, and the core contains a water responsive immobilizing agent to immobilize the superabsorbent polymer prior to water insult. The tube-shaped swelling chamber is a portion of the absorbent core containing superabsorbent polymer that is delimited by a plurality of continuous permanent seals that each join together overlapping portions of the core wrap and prevent superabsorbent polymer from moving across the seals.
(FR)Une âme absorbante comprennent une matière absorbante contenue dans une enveloppe d'âme qui comprend une couche de substrat perméable aux liquides. L'âme contient environ 87 % à 100 % de polymère superabsorbant, et un compartiment dilatable en forme de tube ayant un rapport longueur/largeur inférieur ou égal à 5 : 1. La zone d'âme est au moins deux fois supérieure à la zone du compartiment dilatable, et l'âme contient un agent d'immobilisation sensible à l'eau pour immobiliser le polymère superabsorbant avant qu'il ne soit endommagé par l'eau. Le compartiment dilatable en forme de tube est une partie de l'âme absorbante, contenant un polymère superabsorbant, qui est délimité par plusieurs joints continus permanents qui relient chacun les parties se chevauchant de l'enveloppe d'âme et empêchent le polymère superabsorbant de passer à travers les joints d'étanchéité.
