Abstract
"ESTRUTURA ABSORVENTE EM CAMADAS COM UM PESO-BASE DIVIDIDO EM ZONAS". Um artigo absorvente diferente inclui um núcleo absorvente com várias camadas absorventes, onde as camadas absorventes interagem de tal modo que localizam, preferencialmente, o líquido absorvido em uma camada de absorção de alta saturação indicada. A localização do líquido nesta camada de absorção aumenta o potencial desta camada em deslocar o líquido através de ação capilar devido ao nível mais elevado de saturação e quantidade aumentada de líquido disponível. Em outros aspectos, pelo menos uma região de camada primária pode ter uma distribuição de peso-base seletivamente dividido em zonas, não-uniforme. Configurações específicas de pelo menos uma região de camada primária podem ser construídas com uma área-alvo da região de camada primária tendo um peso-base menor do que um peso-base de outra porção não-alvo da região de camada primária."ABSORBENT STRUCTURE IN LAYERS WITH A BASE WEIGHT DIVIDED IN ZONES". A different absorbent article includes an absorbent core with several absorbent layers, where the absorbent layers interact in such a way that they preferentially locate the absorbed liquid in an indicated high saturation absorption layer. The location of the liquid in this absorption layer increases the potential of this layer to displace the liquid through capillary action due to the higher level of saturation and increased amount of liquid available. In other respects, at least one primary layer region may have a selectively zoned, non-uniform basis weight distribution. Specific configurations of at least one primary layer region can be constructed with a target area of the primary layer region having a basis weight less than a base weight of another non-target portion of the primary layer region.
