Abstract

LA PRESENTE INVENCION SE REFIERE, EN UNA REALIZACION PREFERIDA, A UNA LAMINA COMPUESTA, ESTIRABLE, EXTENSIBLE Y PERMEABLE A LOS FLUIDOS, QUE COMPRENDE UNA CAPA DE PELICULA CONFORMADA, EXPANDIDA MACROSCOPICAMENTE, TRIDIMENSIONAL Y PERFORADA, Y UNA CAPA FIBROSA, PREFERENTEMENTE DE MATERIAL NO TEJIDO, ENCOLADA A UN LADO DE LA CAPA DE PELICULA CONFORMADA. LA BANDA COMPUESTA SE ENCUENTRA MICROONDULADA EN AL MENOS UNA DIRECCION, DE MANERA QUE LA BANDA COMPUESTA MUESTRE EXTENSIBILIDAD, Y A SER POSIBLE TAMBIEN RETRACTABILIDAD, EN ESA DIRECCION. LA BANDA COMPUESTA MUESTRA UN EMPOTRAMIENTO DE ESCALA FINA ENTRE LA CAPA DE PELICULA CONFORMADA Y LA CAPA NO TEJIDA EN LOS MICROPLIEGUES, PROPORCIONANDO UN CONTACTO INTIMO ENTRE LAS CAPAS PARA MEJORAR LAS PROPIEDADES DE TRANSPORTE DE FLUIDOS MIENTRAS LAS TRES DIMENSIONES DE LA PELICULA FORMADA PROPORCIONAN UNA SEPARACION AUTONOMA ENTRE LAS CAPAS. LAS BANDAS COMPUESTAS DE LA PRESENTE INVENCION SON PARTICULARMENTE ADECUADAS PARA UTILIZAR COMO LAMINA SUPERIOR DE UN ARTICULO ABSORBENTE, A FIN DE PROPORCIONAR UNA MEJOR ESTIRABILIDAD Y EXTENSIBILIDAD, Y ACOMODARSE A UNA AMPLIA VARIEDAD DE CONDICIONES DE USO Y PERMITIR QUE EL ARTICULO ABSORBENTE SE ADAPTE MEJOR AL CUERPO DEL PORTADOR, MEJORANDO SU COMODIDAD GRACIAS A SU MAYOR FLEXIBILIDAD. LA SUPERFICIE MICROONDULADA PROPORCIONA TAMBIEN AL PORTADOR UNA AGRADABLE Y SUAVE IMPRESION VISUAL Y TACTIL. LA PRESENTE INVENCION SE REFIERE TAMBIEN A UN PROCEDIMIENTO PARA REALIZAR UNA BANDA COMPUESTA EXTENSIBLE, ESTIRABLE Y PERMEABLE A LOS FLUIDOS, QUE COMPRENDE LOS PASOS DE: (A) PROPORCIONAR UNA CAPA DE PELICULA CONFORMADA, EXPANDIDA MACROSCOPICAMENTE, TRIDIMENSIONAL Y PERFORADA; (B) PROPORCIONAR UNA CAPA FIBROSA; (C) ENCOLAR LA CAPA FIBROSA A UN LADO DE LA CAPA DE PELICULA CONFORMADA PARA DISPONER ASI UNA BANDA COMPUESTA; (D) MICROONDULAR LA BANDA COMPUESTA AL MENOS EN UNA DIRECCION, DE MANERA QUE LA BANDA COMPUESTA SE CONTRAIGA EN ESA DIRECCION, Y LA CAPA DE PELICULA CONFORMADA PERMANEZCA PRACTICAMENTE TRIDIMENSIONAL Y MACROSCOPICAMENTE EXPANDIDA.
