Abstract

Un artículo absorbente distintivo inCLlcuye un nucleo absorbente que tiene multiples capas absorbentes, en donde las capas absorbentes interactuan de manertal que ubican preferencialmente el líquido absorbido en una capa de transporte designada, de alta saturacion. La ubicacion del líquido dentro de esta capa detransporte aumenta el potencial de esta capa para desplazar el líquido a través de la accion capilar debido al alto nivel de saturacion y al aumento de lacantidad de líquido disponible. La capacidad de absorcion del sistema absorbente se mantiene o se mejora por sobre los sistemas actuales al mantener unasegunda capa del sistema absorbente a niveles de saturacion bajos a través de tantas descargas del producto como sea posible, a lavez que se provee unrendimiento optimo de absorcion a través del control apropiado de las propiedades del compuesto. La baja saturacion de esta capa provee un volumen vacío parala descarga entrante así como una baja permeabilidad, por lo tanto aumenta la velocidad de absorcion del sistema absorbente en su conjunto, pero la estructurade la capa de baja saturacion también se equilibra para proveer un nivel alto adecuado de tension capilar a fin de proporcionar un control suficiente dellíquido queposibilite impedir la ocurrencia de filtraciones. Esta capa de baja saturacion se utiliza además de un material de flujo y provee la funcionalidadde absorcion sumada a la provista por el material de flujo. En aspectos particulares de la invencion, por lo tanto, la capa contacto-cuerpo no se utiliza comocapa de transporte de alta saturacion, sino como capa de absorcion. Asimismo, esta disposicion permite que la capa de absorcion esté en contacto directo con ellíquido entrante, y de este modo da lugar a un acceso más inmediato y a una funcion de absorcion mejorada. En aspectos adicionales, por lo menos una region decapa principal puede tener una distribucion de peso base no uniforme distribuido selectivamente por zonas. Configuraciones particulares de por lo menos unaregion de capa principal pueden ser construídas con un área objetivo de la region de capa principal que tiene un peso base que no es menor que un peso base deA distinctive absorbent article includes an absorbent core that has multiple absorbent layers, wherein the absorber layers interact with the handle that preferentially locates the absorbed liquid in a designated, high saturation transport layer. The location of the liquid within this transport layer increases the potential of this layer to move the liquid through the capillary action due to the high level of saturation and the increase in the amount of liquid available. The absorption capacity of the absorbent system is maintained or improved over current systems by maintaining a second layer of the absorbent system at low saturation levels through as many product discharges as possible, while providing optimum absorption performance at through proper control of the properties of the compound. The low saturation of this layer provides an empty volume for the incoming discharge as well as a low permeability, therefore it increases the absorption rate of the absorbent system as a whole, but the structure of the low saturation layer is also balanced to provide a high level adequate capillary tension in order to provide sufficient control of the liquid that makes it possible to prevent the occurrence of leaks. This low saturation layer is used in addition to a flow material and provides the absorption functionality added to that provided by the flow material. In particular aspects of the invention, therefore, the contact-body layer is not used as a high saturation transport layer, but as an absorption layer. Also, this arrangement allows the absorption layer to be in direct contact with the incoming liquid, and thus results in more immediate access and an improved absorption function. In additional aspects, at least one major stripping region may have a non-uniform base weight distribution selectively distributed by zones. Particular configurations of at least one main layer region can be constructed with a target area of the main layer region having a base weight that is not less than a base weight of
