Abstract

COMPRENDEN DOS REGIONES VISUALMENTE DISTINTAS ENTRE SI DENTRO DE LA MISMA COMPOSICION DEL MATERIAL, LA PRIMERA REGION EXPERIMENTA UNA DEFORMACION DEL NIVEL MOLECULAR Y LA SEGUNDA REGION UNA DEFORMACION GEOMETRICA, LA SEGUNDA REGION INCLUYE UNA PLURALIDAD DE ELEMENTOS LEVANTADOS SEMEJANTES A COSTILLAS (CON UN EJE MAYOR Y UNO MENOR) Y LA PRIMERA REGION ESTA LIBRE DE ESTOS ELEMENTOS. LA PRIMERA REGION COMPRENDE ENTRE EL 2% AL 90 % DE LA PRIMERA SUPERFICIE, AMBAS REGIONES COMPRENDEN POR LO MENOS UNA CAPA DE MATERIAL DE PELICULA DE POLIETILENO O MEZCLAS DE ESTE, EL MATERIAL DE PELICULA CONSTA DE UN POLIMERO BASADO EN UN CATALIZADOR DE METALOCENO. LA PRIMERA Y LA SEGUNDA REGIONES SON LINEALES, CURVILINEAS. DOS O MAS DE LAS PRIMERAS Y SEGUNDAS REGIONES TIENEN DIFERENTES ANCHOS. EXHIBE UN COMPORTAMIENTO SEMEJANTE AL ELASTICO A LO LARGO DE POR LO MENOS UN EJE. CUANDO ES SOMETIDO A UN ESTIRAMIENTO APLICADO EN UNA DIRECCION PARALELA A ESTE EJE, ESTA PRIMERA REGION REGRESA A SU LONGITUD DE TRAYECTORIA PROYECTADA NO ESTIRADA CUANDO SE LIBERA ESTE ESTIRAMIENTO APLICADO. SE USAN EN ARTICULOS ABSOBENTES COMO TOALLAS SANITARIAS, PANALES, VENDAJES Y OTROSTHEY INCLUDE TWO REGIONS VISUALLY DIFFERENT BETWEEN WITHIN THE SAME COMPOSITION OF THE MATERIAL, THE FIRST REGION EXPERIENCES A DEFORMATION OF THE MOLECULAR LEVEL AND THE SECOND REGION INCLUDES A GEOMETRICAL DEFORMATION ELEVANT AND SOME EAST ONE MINOR) AND THE FIRST REGION IS FREE OF THESE ELEMENTS. THE FIRST REGION INCLUDES BETWEEN 2% TO 90% OF THE FIRST SURFACE, BOTH REGIONS INCLUDE AT LEAST ONE LAYER OF POLYETHYLENE FILM MATERIAL OR MIXTURES OF IT, THE FILM MATERIAL CONSISTS OF A POLYMER BASED ON A METAL CATALYST. THE FIRST AND SECOND REGIONS ARE LINEAR, CURVILINE. TWO OR MORE OF THE FIRST AND SECOND REGIONS HAVE DIFFERENT WIDTHS. IT EXHIBITS AN ELASTIC-LIKE BEHAVIOR ALONGSIDE AT LEAST ONE AXIS. WHEN SUBMITTED TO A STRETCH APPLIED IN A PARALLEL DIRECTION TO THIS AXIS, THIS FIRST REGION RETURNS TO ITS LENGTH OF PROJECTED PATH NOT STRETCHED WHEN THIS APPLIED STRETCH IS RELEASED. IT IS USED IN ABSOBENT ITEMS SUCH AS SANITARY TOWELS, HONEYCOMBS, BANDAGES AND OTHERS
