る。2. Description of the Related Art Conventionally, as a filter used for cigarettes, a white filter showing a feeling of cleanliness is preferred because it can be held in the mouth, and it is used for many cigarettes.
A colored filter having a design effect is also disclosed in JP-A-60-989.
No. 78, etc. That is, JP-A-60-9
Japanese Patent No. 8978 proposes a method of obtaining a colored filter by opening a cellulose acetate fiber tow and then attaching a plasticizer in which a colorant is uniformly dispersed.

In that case, the colorant in the plasticizer is not sufficiently dissolved, and when it is present as an undissolved substance in the plasticizer, the undissolved substance precipitates and separates with time. A filter made by affixing a plasticizer in such a state that precipitates and separates easily to the cellulose acetate fiber tow has a dark colored portion on the filter cross section and a non-colored portion on the filter cross section due to the presence of undissolved material, and the filter cross section is colored. Spots occur.

It is colored.
At this time, by including a solvent having compatibility with the colorant and the plasticizer, the colorant and the plasticizer are uniformly dissolved in the solvent,
It is dispersed and colored deeply and uniformly. Therefore, when there is no solvent having compatibility with the colorant and the plasticizer, and the colorant and the plasticizer are only included, the colorant is not uniformly dissolved in the plasticizer, resulting in coloring unevenness and a coloring effect. Will be insufficient.

In determining the blending ratio of the colorant, the plasticizer, and the solvent compatible with the colorant and the plasticizer, it is important to determine the filter hardness that the tobacco filter originally has as a practical function. This is the amount of plasticizer added. For example, when triacetylglycerin is used as a plasticizer, the amount added is preferably 2 to 20 wt%, and more preferably 5 to 15 wt% with respect to the fiber tow of the filter material in order to maintain an appropriate filter hardness. It is also necessary to determine the proportions of the solvent and the colorant in the mixed solution based on the above numerical values.

The ratio of the colorant and the solvent to the plasticizer is preferably 5 to 50 wt%, more preferably 20 to 40 wt%.

Next, this colored stock solution is gradually put into a container such as a beaker containing a predetermined amount of plasticizer and uniformly dispersed and dissolved to obtain a colored mixed solution. In addition,
The stirring conditions such as stirring speed and stirring time are not particularly limited.

The colored mixed solution is supplied from the bottom of the tank to the plasticizer applicator section by a gear pump. On the other hand, the filter material supplied to the plug machine, for example, cellulose acetate fiber tow, is stretched between two roll pairs to be processed into a bulky state in which short fibers are separated from each other, and then in a plasticizer applicator. The colored mixed solution is uniformly or indirectly attached to the fiber tow through spraying or felt.

る。The colored fiber tow is then bundled so as to have a constant diameter and formed into a rod shape at the winding tube portion. A colored filter plug made of the colored filter material of the present invention is manufactured by winding a winding paper around the outer circumference of the tow in the shape of a rod and cutting it to a predetermined length. This plug is cut to an appropriate length to make a cigarette filter as shown in FIG.

In this case, when the spread tow is bundled into a circular rod shape, it can be wound up so as to be wrapped with this grooved tape-like material, whereby a filter having a colored outer peripheral portion can be obtained. By plasticizing into a tape shape, the fibers are compacted, and the colored spots are further improved and the color tone is darker than in the case of a normal filter.

のである。EFFECT OF THE INVENTION Since the coloring filter of the present invention is impregnated with the plasticizer in which the colorant is uniformly dissolved by the solvent, it is possible to develop a dark color tone even with a small amount of the colorant to be used, thus giving a colorful coloring. By applying it, it has a colorful design and is differentiated to appeal to the eyes of consumers. In addition, since the colorant is uniformly dissolved in the plasticizer, it is not necessary to continuously stir the plasticizer when manufacturing the tobacco filter, and thus the manufacturing can be performed with high productivity.
Further, the cigarette provided with the filter made of the colored filter of the present invention has excellent design and fashionability.
