Se describirá el caso en el que, se utiliza un filtro de cigarrillo de acetato de celulosa como un material de filtro Como se ha mencionado arribamente, es una práctica común añadir un plastificante, tal como triacetina, a un filtro, en una cantidad correspondiente a un 5 a 10% en peso basado en el peso de la fibra de acetato de celulosa, con el fin de impartir una dureza determinada al filtro. Sin embargo, cuando se emplea el papel de elevada rigidez y elevada permeabilidad acorde con la presente invención, se puede conseguir la misma dureza del filtro que hasta ahora incluso con la adición de plastificante en una cantidad que corresponde a menos del 5% (incluyendo 0%), basado en el peso de la fibra de acetato de celulosa. No hace felevada indicar que cuando se añade el plastificante a la fibra de The case will be described in which, a cellulose acetate cigarette filter is used as a filter material. As mentioned above, it is common practice to add a plasticizer, such as triacetin, to a filter, in an amount corresponding to 5 to 10% by weight based on the weight of the cellulose acetate fiber, in order to impart a determined hardness to the filter. However, when the paper of high rigidity and high permeability according to the present invention is used, the same filter hardness can be achieved as up to now even with the addition of plasticizer in an amount corresponding to less than 5% (including 0 %), based on the weight of the cellulose acetate fiber.

Ejemplos Examples
A continuación se describirá la presente invención con referencia a los siguientes Ejemplos. The present invention will now be described with reference to the following Examples.
Ejemplo 1 Example 1
Se produjeron tapones de filtro de acuerdo con el procedimiento de rutina, utilizando los papeles indicados en la Tabla 1 anterior como envolturas de tapón de filtro. El material de filtro empleado consistía en un filtro de cigarrillo de acetato de celulosa convencional que tenía triacetina añadida al mismo, en una cantidad correspondiente al 6% en peso basado en el peso del filtro de cigarrillo de acetato de celulosa. Cada uno de los tapones de filtro tenía una circunferencia de 24,5 mm y una longitud de 25 mm. Cada una de las envolturas de tapón de filtro cubría la circunferencia del material de filtro en justa relación. Se midió la dureza de cada uno de los filtros obtenidos. Filter caps were produced according to the routine procedure, using the papers indicated in Table 1 above as filter plug wraps. The filter material used consisted of a conventional cellulose acetate cigarette filter having triacetin added thereto, in an amount corresponding to 6% by weight based on the weight of the cellulose acetate cigarette filter. Each of the filter caps had a circumference of 24.5 mm and a length of 25 mm. Each of the filter plug wraps covered the circumference of the filter material in fair relationship. The hardness of each of the filters obtained was measured.
En naturaleza, la dureza de cada uno de los filtros se debería medir en el estado del filtro acoplado al cigarrillo. Sin embargo, debido a problemas relacionados con los instrumentos de medida, es difícil medir la dureza de cada uno de los filtros en el estado del filtro acoplado al cigarrillo. Por lo tanto, se midió la dureza de cada uno de los filtros en forma de un tapón de filtro antes de su instalación en el cigarrillo (en lo sucesivo, la dureza de filtro se habrá medido por el mismo método de medición). In nature, the hardness of each of the filters should be measured in the state of the filter attached to the cigarette. However, due to problems related to measuring instruments, it is difficult to measure the hardness of each of the filters in the state of the filter coupled to the cigarette. Therefore, the hardness of each of the filters was measured in the form of a filter plug before being installed in the cigarette (hereinafter, the filter hardness will have been measured by the same measurement method).
La dureza del filtro se midió utilizando NFQA (instrumento de medida de calidad del filtro) fabricado por JT TOSHI. Los resultados se muestran en la FIG. 4. La dureza del filtro se calculó a partir de una deformación que se produce en el filtro tras la aplicación de una determinada carga. En consecuencia, a menor deformación, mayor es la dureza del filtro. Por lo tanto, en la FIG. 4, cuanto menor es el valor de la dureza del filtro, más duro es el filtro. The hardness of the filter was measured using NFQA (filter quality measuring instrument) manufactured by JT TOSHI. The results are shown in FIG. 4. The hardness of the filter was calculated from a deformation that occurs in the filter after the application of a certain load. Consequently, the less deformation, the greater the hardness of the filter. Therefore, in FIG. 4, the lower the hardness value of the filter, the harder the filter.
Se desprende de la FIG. 4 que la dureza de filtro de cada uno de los tapones de filtro, proporcionada por los papeles de elevada rigidez y de elevada permeabilidad S1 a S4 acordes con la presente invención, se incrementa con respecto a la del tapón de filtro provisto con la envoltura de tapón de filtro P empleada habitualmente en la actualidad P. Todos los tapones de filtro provisto con el papel de elevada rigidez y de elevada permeabilidad S1 a S4 acordes con la presente invención mostraron una permeabilidad al aire de 1000 unidades CORESTA o superior. Además, se podría conseguir el papel S4 de elevada rigidez que mostrase una permeabilidad al aire equivalente a la de la envoltura de tapón de filtro P empleada habitualmente en la actualidad. It follows from FIG. 4 that the filter hardness of each of the filter caps, provided by the high stiffness and high permeability papers S1 to S4 in accordance with the present invention, is increased with respect to that of the filter plug provided with the envelope of Filter cap P commonly used today P. All filter caps provided with the paper of high rigidity and high permeability S1 to S4 according to the present invention showed an air permeability of 1000 CORESTA units or higher. In addition, the paper S4 of high stiffness could be achieved which showed an air permeability equivalent to that of the filter plug wrapper P currently employed today.
Por lo tanto, el uso del papel de elevada rigidez y de elevada permeabilidad acorde con la presente invención, hace que sea posible no sólo lograr la retención o incremento de la dureza de filtro, sino también evitar los problemas del estado de la técnica de hacer orificios de ventilación, es decir, un aumento de coste de fabricación de los cigarrillos, una versatilidad baja para una variedad de productos de cigarrillos, incluyendo un cigarrillo bajo contenido de alquitrán o similares y una pobre estabilidad de la calidad del producto. Therefore, the use of high stiffness and high permeability paper in accordance with the present invention makes it possible not only to achieve retention or increase of filter hardness, but also to avoid problems of the state of the art of making ventilation holes, that is, an increase in the cost of manufacturing cigarettes, low versatility for a variety of cigarette products, including a low tar or similar cigarette and poor product quality stability.
Ejemplo 2 Example 2
Se produjeron tapones de filtro, con el mismo tamaño que en el Ejemplo 1, utilizando la envoltura P del tapón de filtro convencional y el papel de elevada rigidez y de elevada permeabilidad S4 indicado en la Tabla 1. El material de filtro era el mismo filtro de cigarrillo de acetato de celulosa convencional que en el Ejemplo 1, pero se cambió la cantidad de triacetina añadida al filtro de cigarrillo (cantidades equivalentes al 0 a 12% en peso basado en el peso de la fibra de acetato de celulosa). La dureza de cada uno de los tapones de filtro obtenidos se midió de la misma manera que en el Ejemplo 1. Los resultados se muestran en la FIG. 5. En la FIG. 5, la línea a indica los resultados de la utilización de la envoltura P de tapón de filtro, y la línea b indica los resultados de la utilización de papel S4 de elevada rigidez y de elevada permeabilidad. Filter caps were produced, with the same size as in Example 1, using the wrapper P of the conventional filter plug and the high stiffness and high permeability paper S4 indicated in Table 1. The filter material was the same filter. of conventional cellulose acetate cigarette than in Example 1, but the amount of triacetin added to the cigarette filter was changed (amounts equivalent to 0 to 12% by weight based on the weight of the cellulose acetate fiber). The hardness of each of the filter plugs obtained was measured in the same manner as in Example 1. The results are shown in FIG. 5. In FIG. 5, line a indicates the results of the use of the filter plug envelope P, and line b indicates the results of the use of paper S4 of high rigidity and high permeability.
Se desprende de la FIG. 5 que cuando se utiliza el papel S4 de elevada rigidez y de elevada permeabilidad, independientemente de la cantidad de triacetina añadida, la dureza del filtro se incrementa con respecto a la del tapón de filtro usando la envoltura P de tapón de filtro convencional. It follows from FIG. 5 that when the paper S4 of high rigidity and high permeability is used, regardless of the amount of triacetin added, the hardness of the filter is increased with respect to that of the filter plug using the wrapper P of conventional filter plug.
Como se ha mencionado anteriormente, en los cigarrillos actuales, se añade triacetina al filtro en una cantidad del 5 a 10% en peso basado en el peso del material de filtro. Sin embargo, se observa que cuando se utiliza papel S4 de elevada rigidez y de elevada permeabilidad, se puede aumentar la dureza de filtro sin necesidad de aumentar la cantidad de triacetina. As mentioned above, in current cigarettes, triacetin is added to the filter in an amount of 5 to 10% by weight based on the weight of the filter material. However, it is noted that when S4 paper of high rigidity and high permeability is used, the filter hardness can be increased without the need to increase the amount of triacetin.
En los casos en los que la cantidad de triacetina es menor, se ha encontrado que la dureza del filtro mostrada cuando se utiliza la envoltura P de tapón de filtro convencional y la cantidad de triacetina es de aproximadamente el 6% en peso, se puede alcanzar mediante el uso de triacetina en una cantidad de aproximadamente 3% en peso si In cases where the amount of triacetin is lower, it has been found that the hardness of the filter shown when the conventional filter plug envelope P is used and the amount of triacetin is approximately 6% by weight, it can be achieved by using triacetin in an amount of approximately 3% by weight if
