があった。However, since the fibers are welded at many points, the filter is not easily dispersed when the filter is no longer needed after smoking and is discarded into the environment. Since it retains its shape for a long time, it has drawbacks such as impairing the aesthetics of the environment. In addition, the filter
Is made of one filter material with a length of about 25 mm, so wrap the wrapping paper with a water-soluble adhesive,
The wrapping paper itself uses a water-dispersible paper or a sheet-like material made of a water-soluble material, and instead of welding the fibers together, a water-soluble adhesive is used for bonding, or no adhesive is used. Even if a fiber filter that is not adhered at all is used, if it is left outdoors, the paper wrapper will separate or disperse mainly due to rainwater, and the adhesive will also flow out, causing the fibers The shape of the filter collapses because the adhered parts of the filter separate, but the fibers do not disperse finely as a result of the entanglement of the fibers, and the filter does not easily disperse because it remains as one lump, Since the shape of the period is retained, there are drawbacks such as impairing the aesthetics of the environment.

材の個数が多くなり過ぎ作業性が悪くなる。When the length of the filter material exceeds 8 mm, when the filter material is left outdoors, the wrapping paper is separated or dispersed mainly by rainwater and flows out, and the adhesive flows out to bond the fibers together. The shape of the filter collapses due to the separation of the parts that had been separated, but the fibers do not disperse finely as a result of being entangled with each other, and they remain as a single mass, so in the environment due to the action of water such as rainwater It does not achieve the object of the present invention to provide a cigarette filter which is easily dispersed and does not impair the aesthetics of the environment. Also, 0.5m
When the length is less than m, if the filter is formed to have a length of about 15 mm, the number of filter materials constituting the filter becomes too large and workability deteriorates.

が分散し易くなるので好ましい。The filter material and the cigarette of the present invention are wrapped with a wrapping paper, and as such a wrapping paper, addition of additives for imparting water resistance or post-treatment is not performed at all or reduced. Examples of the paper have a water-dispersing ability, such as filter-wrapping paper and toilet paper that have been conventionally used. The water-soluble adhesive may be used as the adhesive used for winding this. If a water-soluble material is used, the wrapping paper is separated from the filter material in a short period of time due to the loss of the adhesive due to rainwater, and the function of protecting the inside is lost, so that the filter material is easily dispersed, which is preferable. .

A bundle of 12,000 and 5000 is crimped and opened, and a water-soluble adhesive is sprayed on the surface with an aqueous solution of starch paste. Immediately after that, CMC is used as a binder to disperse water. A filter was prepared by rolling up with paper. The adhesive of the prepared filter was placed in an atmosphere of a temperature of 20 ° C. and a relative humidity of 65% for about 72 hours in order to dry it, and the length was 20 mm by cutting it.
(Comparative Example), 15 mm (Comparative Example), 10 mm (Comparative Example), 5 mm, and 3 mm were prepared in large numbers. 300
One filter-sample was placed in 100 ml of water in an Erlenmeyer flask and shaken with a shaker for 5 minutes, and then the degree of dispersion of the filter-sample was visually observed. The results are shown in Table-1. The observation result is 10 when the fibers are completely dispersed individually, and the fibers are not dispersed.
