Abstract

LA PRESENTE INVENCIÓN SE REFIERE A ARTÍCULOS ABSORBENTES DE LÍQUIDO FORMADOS INTEGRALMENTE POR UN MATERIAL PARTICULADO QUE INCLUYEN UNA PRIMERA Y SEGUNDA ZONA EN UNA RELACIÓN ÍNTIMA DE COMUNICACIÓN DE FLUIDO, CADA ZONA TIENE UNA CANTIDAD DE INTERSTICIOS INTERPARTÍCULA QUE ADMITEN EL PASAJE DEL LÍQUIDO, DONDE EL LÍQUIDO CONTENIDO EN UNA DE DICHAS ZONAS ES CAPAZ DE MIGRAR HACIA LA OTRA DE DICHAS ZONAS, DICHO ARTÍCULO ABSORBENTE DE LÍQUIDO CONTIENE UN AGLUTINANTE, DICHA PRIMERA ZONA TIENE UNA CONCENTRACIÓN PROMEDIO MAYOR DE AGLUTINANTE QUE DICHA SEGUNDA ZONA. DICHO ARTÍCULO ABSORBENTE PUEDE TENER LA FORMA DE UNA HOJA, DICHAS ZONAS PUEDEN CONSTITUIR CAPAS SUPERPUESTAS DE DICHA HOJA. ADICIONALMENTE, EL ARTÍCULO ABSORBENTE PUEDE INCLUIR UNA TERCERA ZONA UBICADA ENTRE LA PRIMERA Y LA SEGUNDA ZONA Y TIENE UNA DENSIDAD INFERIOR QUE AQUÉLLAS Y UN AGLUTINANTE EN MENOR CONCENTRACIÓN QUE LAS MISMAS. EN OTRO CAMPO DE LA INVENCIÓN, EL ARTÍCULO ABSORBENTE PUEDE INCLUIR UN MATERIAL FIBROSO, TAL COMO LA CELULOSA. CAPAS DE TRANSFERENCIA PARA UN PRODUCTO ABSORBENTE DESECHABLE QUE COMPRENDE UN ARTÍCULO ABSORBENTE OBJETO DE ESTA INVENCIÓN. TALES CAPAS DE TRANSFERENCIA INCLUYE PARTÍCULAS QUE DEFINEN MULTIPLICIDAD DE INTERSTICIOS INTER-PARTÍCULA QUE ADMITEN EL PASO DEL LÍQUIDO, INCLUYE UNA SUPERFICIE DE ADQUISICIÓN DEL LÍQUIDO A TRAVÉS DE LA CUAL EL LÍQUIDO PUEDE INGRESAR A DICHA CAPA Y UNA SUPERFICIE DE LIBERACIÓN DE LÍQUIDO PARA EGRESAR DE LA MISMA, DICHA CAPA TIENE UN AGLUTINANTE. MÉTODOS PARA FABRICAR UN ARTICULO ABSORBENTE DE LÍQUIDOS QUE COMPRENDE LOS PASOS DE: - Formar un material partículado en una hoja que tiene una primera y segunda caras principal una cantidad de intersticios interpartícula que admiten el paso del líquido; y - aplicar el aglutinante a dicha hoja para proporcionar una mayor concentración en las cercanías de la primera cara principal que en la segunda cara principal.
