Abstract

Se describen elementos absorbentes útiles para contener líquidos corporales tal como orina. Estos elementos absorbentes comprenden por lo menos un absorbente osmótico (preferiblemente un polímero absorbente formador de hidrogel) y un material de gran área superficial, y tienen alta capacidad de succión capilar. Para los propósitos de la presente revelación, la capacidad de succión capilar se mide en términos de la capacidad del elemento de absorber líquido a elevadas alturas capilares, que generalmente se encuentran cuando el elementos se coloca en un artículo absorbente. En particular, la capacidad de succión capilar se mide en términos de la capacidad absorbente por sorción capilar del elemento, que se mide según el método de sorción Capilar que se describe en la sección Métodos de Prueba. Un elemento absorbente de almacenamiento con alta succión capilar el cual tiene una capacidad absorbente de sorción capilar a una altura de 35 cm de por lo menos 12 g/g. Un elemento absorbente de almacenamiento de alta succión capilar el cual tiene una capacidad absorbente de sorción capilar a una altura de 70 cm de por lo menos 7 g/g aproximadamente.
