Abstract

"ARTIGO ABSORVENTE COM FOLHA DE FUNDO PERMEáVEL A GASES COMPREENDENDO ABERTURAS CAPILARES OBLìQUAS". A presente invenção refere-se a artigos absorventes, tais como fraldas para bebês, artigos para incontinência de adultos, e particularmente, absorventes higiênicos ou protetores de calcinhas, que têm uma folha de topo de filme com aberturas sobre a superfície voltada para o usuário durante o uso. De acordo com a presente invenção, os artigos são dotados também de folha de fundo com aberturas, para se conseguir permeabilidade a gases. A folha de fundo compreende pelo menos uma camada permeável a gases feita de uma manta tridimensional resiliente que consiste de um filme polimérico impermeável a líquidos, com aberturas. Essas aberturas formam capilares que não são perpendiculares ao plano do filme, mas estão dispostos formando um ângulo menor do que 90° com o plano do filme.
