Abstract

ARTICULO ABSORBENTE, PROCEDIMIENTO PARA PRODUCIRLO Y PROCEDIMIENTO PARA PREPARAR UN MATERIAL POLIMERO ESPUMADO, EN DONDE EL ARTICULO COMPRENDE UN MATERIAL DE POLIMERO HIDROFILO ABSORBENTE FIJADO A UNA O MAS CAPAS DE UN SUSTRATO DE ESTERILLA DE FIBRAS NO TEJIDAS, PAPEL TISU, BORRA DE CELULOSA, ESPUMA POLIMERA, PAPEL CRESPADO, PELICULA DE POLIMERO O PAPEL DE SUPERFICIE DURA. EL ARTICULO PUEDE LLEVAR UNA LAMINA INFERIOR IMPERMEABLE AL AGUA Y UNA LAMINA VISTA PERMEABLE AL AGUA, CONSTITUYENDO UNA ALMOHADILLA ABSORBENTE. EL ARTICULO SE PRODUCE FIJANDO AL SUSTRATO UNA COMPOSICION QUE COMPRENDE UN AGENTE DE SOPLADO Y UN POLIMERO HIDROFILO HINCHABLE EN AGUA, Y CALENTANDO HASTA ESPUMAR LA COMPOSICION. EL MATERIAL POLIMERO ESPUMADO SE PREPARA PONIENDO EN CONTACTO UNA SOLUCION DE POLIMERO HIDROFILO PRENEUTRALIZADO Y UN AGENTE DE SOPLADO, Y CALENTADO HASTA ESPUMAR LA COMPOSICION. EL INVENTO ES APLICABLE A PAÑOS HIGIENICOS, PAÑALES Y ARTICULOS ABSORBENTES SEMEJANTES.
