Abstract

<B>TRAMAS ABSORVENTES DIVIDIDAS EM ZONAS DUPLAS<D>. é revelada uma trama absorvente flexível tridimensionalmente dividida em zonas duplas, a qual é adequada como forro do lado do corpo para artigos absorventes como absorventes femininos, fraldas e semelhantes. Quando usada como um forro em artigos absorventes, a trama dividida em zonas duplas combina as vantagens de películas com aberturas e camadas de revestimento macias não-trançadas em uma estrutura, enquanto é ainda inerentemente hidrófila. O forro compreende uma trama de folha de base hidrófila flexível a úmido que tem uma topografia tridimensional compreendendo regiões elevadas para sobre as quais a matéria hidrófoba é depositada ou estampada e diversas regiões rebaixadas separadas. Em uma modalidade preferida, a matéria hidrófoba aplicada às regiões elevadas da folha de base compreende fibras hidrófobas em uma trama não-trançada contígua a qual foi dotada de aberturas ou então fendas ou outros furos, de tal modo que as aberturas ou furos sobrepõem-se a uma porção das regiões rebaixadas. As regiões hidrófobas elevadas aumentam a sensação de secura e promovem o fluxo de fluido em direção às regiões hidrófilas inferiores, as quais compreendem as regiões rebaixadas expostas da folha de base. A folha de base está preferivelmente em comunicação de líquido com o material absorvente subjacente, mais preferivelmente um material celulósico assentado a ar estabilizado ou felpa estabilizada comprimida de tal modo que o material absorvente pode absorver o fluido para fora da folha de base pela ação capilar. Quando fibras hidrófobas macias são depositadas sobre as regiões elevadas, o forro proporciona também uma sensação semelhante a pano, macio além da sensação de secura durante o uso.
