Abstract

La presente invencion provee un proceso para formar una tela tridimensional macroscopicamente expandida permeable al fluido que tiene una superficiefuncional mejorada de una hoja de material polimerico que tiene una primera superficie y una segunda superficie. Una pluralidad de depositos discretos deun material resinoso resistente al agua que tienen un tiempo abierto predeterminado se depositan en la primera superficie de la hoja. Los depositosde material resinoso son atraidos hacia arriba desde la primer superficie de la hoja para formar fibrillas correspondientes durante el tiempo abierto. Despuesde que el material resinoso ha sido curado, la hoja se alimenta a una estructura formadora que tiene superficies opuestas de modo que la hoja esta encontacto con la estructura formadora. La estructura formadora exhibe una multiplicidad de orificios que colocan las superficies opuestas de laestructura formadora en comunicacion por fluido una con otra. Una diferencia de presion hidraulica se aplica a lo largo del espesor de la hoja que essuficientemente grande para causar que la hoja se rompa en aquellas areas que coinciden con los orificios en la estructura formadora y para amoldarse a laestructura formadora mientras mantiene substancialmente la orientacion de las fibrillas. Los pasos de impresion y atraccion se logran preferiblemente por viade un cilindro de impresion por tamiz, y la diferencia de presion hidraulica comprende preferiblemente un chorro de liquido de alta presion.
