Abstract

Procedimiento que sirve para fabricar un material permeable a los gases, cuya permeabilidad difusiva a los gases a una fuerza de arrastre difusivo de 0,21 atmósfera está situada en una gama de 0,5 x 105 cm3/100 pulgadas cuadradas a 2 x 105 cm3/100 pulgadas cuadradas/dia. Este procedimiento consiste en revestir un sustrato poroso por una configuración de zonas constituidas por un material impermeable a los gases, y aumentar esta configuración de zonas para recubrir más del 95% del sustrato poroso, d manera que sólo una aberturas situadas entre dicha configuración de zonas sea permeable a los gases. Este material impermeable a los gases, es, preferentemente, un adhesivo termofusible y el sustrato poroso es, preferentemente, un no-tejido. La etapa de ampliación de la configuración de zonas consiste en extender las zonas sensiblemente redondas para obtener zonas oblongas simultáneamente a su impresión sobre el sustrato poroso hasta que estas zonas oblongas se superpongan parcialmente. Se efectúa la extensión mediante un marco de impresión a una velocidad superficial superior al nivel de estirado del sustrato poroso. En otro modo de realización, esta etapa de ampliación de la configuración de zona consiste en calandrar a través de un espacio fijo el sustrato poroso después de su revestimiento por la configuración de zonas.
