Abstract

<B><MU>MATERIAL CAPAZ DE DISTRIBUIR LìQUIDOS AQUOSOS E ARTIGO ABSORVENTE<MV><D> Expõem-se materiais que são dotados da capacidade de distribuir e de liberar fluidos aquosos, por exemplo, urina, para um material de armazenamento. Estes materiais de distribuição de fluidos são dotados de: A) uma relação de altura de dessorção capilar (isto é, altura a 50% de capacidade) para uma altura de absorção capilar (isto é, altura sob capacidade de 50%) de não mais que 1,8:1; B) uma altura de dessorção capilar de não mais que cerca de 50 cm; C) a capacidade de deslocar por efeito de mecha, urina sintética a 31°C para uma altura de 15 cm em não mais do que cerca de 25 minutos; e D) uma capacidade de deslocamento por efeito de mecha vertical a 15 cm de, pelo menos, cerca de 6 g/g. Expõem-se igualmente artigos absorventes que compreendem esse material de distribuição. Estes artigos absorventes, que são especialmente adequados para absorverem e para reterem fluidos corpóreos aquosos, compreendem: I) uma folha de forro: II) um núcleo absorvente que fica associado com a folha de forro de uma maneira tal que o núcleo absorvente fica posicionado entre a folha de forro e a região de descarga de fluido do usuário do artigo, sendo que o núcleo absorvente compreende um material de distribuição de acordo com a presente invenção; e III) opcionalmente, uma folha de topo, a qual fica posicionada de uma maneira tal que o núcleo absorvente fica localizado entre a folha de forro e a folha de topo.
