Abstract
ESTRUTURA ABSORVENTE TENDO UM EIXO LONGITUDINAL E UM EIXO LATERAL E. Estruturas absorventes e métodos de fabricação são divulgados. Em uma modalidade, uma estrutura absorvente pode compreender primeira e segunda camadas de material de substrato e uma mistura de partículas superabsorventes e adesivo disposto entre a primeira e a segunda camadas de material de substrato. As partículas superabsorventes podem ser dispostas em uma quantidade maior que 400 g/m2, e o adesivo pode ser disposto em uma quantidade menor que 5%, em peso, do peso das partículas superabsorventes, e o adesivo forma uma rede de malha tridimensional compreendendo filamentos adesivos de rede com as partículas superabsorventes imobilizadas dentro da rede de malha e os filamentos adesivos de rede estendendo-se substancialmente ao longo de um espaço tridimensional definido pelos filamentos adesivos de rede e pelas partículas superabsorventes.
