Abstract

"ESTRUTURA ABSORVENTE EM CAMADAS COM UMAREGIãO DE CAMADA HETEROGêNEA". Um artigo absorventedistinto inclui um núcleo absorvente tendo múltiplas camadasabsorventes, onde as camadas absorvente interagem de tal modoque preferencialmente localizam líquido absorvido em uma camadaem mechas com elevada saturação, indicada. A localização dolíquido dentro desta camada em mechas aumenta o potencialdesta camada em mover líquido através da ação capilar devido aonível de saturação mais elevado e grande quantidade de líquidodisponível. Em aspectos específicos, pelo menos uma região decamada primária pode ter uma estrutura heterogênea. Emconfigurações adicionais, pelo menos uma região de camadaprincipal pode incluir uma pluralidade de duas ou maissubcamadas.
