Abstract
<B><MU>ESTRUTURA ABSORVENTE E ARTIGOS ABSORVENTES DESCARTáVEIS QUE COMPREENDEM A MESMA<MV><D>A presente invenção refere-se a estruturas absorventes destinadas a serem usadas em artigos absorventes, que compreendem uma primeira região para aquisição/distribuição de fluido e uma segunda região para armazenamento de fluido. A primeira região compreende materiais que podem ser dotados de uma pressão de dessorção capilar relativamente alta, quando a segunda região compreendem materiais ou elementos que exibem uma pressão de absorção capilar suficientemente alta, de maneira ainda assim a drenarem eficientemente a primeira região. Desta maneira, o material da primeira região é dotado de fluxo cumulativo maior do que 0,075g/cm^2^/seg sob alturas de 12,4 cm, e/ ou um tempo de deslocamento por efeito de mecha menor do que 120 segundos nesta altura, e a segunda região compreende material que satisfaz pelo menos um dos seguintes requisitos:(a) uma capacidade de absorção de pelo menos 15 g/g a 35 cm no teste de capsorção; e/ou (b) uma capacidade de absorção de pelo menos 15 g/g a 0 cm no teste de capsorção e uma eficiência de absorção de pelo menos 55% a 40cm; e/ou (c) uma altura de Absorção por Sorção Capilar a 50% de sua capacidade sob altura de absorção de 0 cm (CSAH 50) de pelo menos 35 cm no teste de capsorção.
