Abstract

On décrit des macrostructures absorbantes et poreuses (52), lesquelles présentent un meilleur pouvoir de traitement de fluides, comprennent des agrégats liés interparticulaires et sont utiles dans des articles absorbants (48) tels que des couches, des articles pour adultes incontinents et des serviettes hygiéniques. On réalise les agrégats liés interparticulaires de ces macrostructures (52) à partir de mélanges de polymères particulaires absorbants présentant différentes propriétés de traitement de fluides, différentes formes, ou les deux. On peut réaliser ces macrostructures (52) à partir d'une grande diversité de polymères absorbants et formant un hydrogel, sans sacrifier les propriétés voulues de traitement de fluides, et sans que ces polymères présentent une tendance au blocage par formation de gel.
