Abstract

Una estructura absorbente en un artículo absorbente tal como un pañal, un pañal de pantaloncito, una guarda de incontinencia, una toalla sanitaria o similar, dicha estructura comprende una combinación de material poroso tal como fibras y/o espuma y material superabsorbente, caracterizado porque, La estructura absorbente contiene al menos 50% en peso de material superabsorbente, basado en el peso total de la estructura en condición seca en al menos un área de esta en la cual material superabsorbente es distribuido, dicho material superabsorbente es reticulado por medio de enlaces iónicos. Una estructura absorbente como se reivindicó en la reivindicación 1, caracterizado porque, el material superabsorbente también esta covalentemente reticulado. Una estructura absorbente como se reivindicó en la reivindicación 1 ó 2, caracterizado porque, el material superabsorbente comprende un polímero con grupos funcionales aniónicos. Una estructura absorbente como se reivindicó en la reivindicación 3, caracterizado porque, el material superabsorbente es un polímero reticulado de poliacrilato que tiene grupos carboxi funcionales.
