Abstract

La presente invencion proporciona un proceso para forma una trama permeable al fluido (70) tridimensional, macroscopicamente expandida que tiene una superficie funcional mejorada compuesta de una hoja de material polimérico que tiene una primera superficie, y una segunda superficie. Se deposite una pluralidad de depositos discretos de un material resinoso resistente al agua que tiene un tiempo de desplegado previamente predeterminado sobre la primera superficie de la hoja. Los depositos del material resinoso son estirados hacia arriba desde la primera superficie de la hoja para forma las fibrillas correspondientes (54) durante el tiempo de desplegado. Después que el material resinoso ha curado, se alimenta la hoja sobre una estructura de formacion que tiene superficies opuestas tal que la hoja está en contacto con la estructura de formacion. La estructura de formacion exhibe una multiplicidad de aberturas que colocan a la superficies opuesta de la estructura de formacion en comunicaciones con un fluido con una de la otra. Se aplica un diferencial de presion de fluido a través del espesor de la hoja, el cual es suficientemente grande para hacer que la hoja rompa en aquellas áreas que coinciden con las aberturas en la estructura de formacion y para conformar con la estructura de formacion mientras que se mantiene sustancialmente la orientacion de las fibrillas (54). Los pasos de impresion y estirado se logran preferiblemente a través de un rodillo de tamiz, y el diferencial de presion de fluido comprende preferiblemente un chorro de líquido a alta presion.
