の商品価値を高めている。Conventionally, various attempts have been made to remove these harmful components without impairing the original aroma and taste of tobacco. Namely, 1. For example, filters manufactured from cellulose acetate fiber tow, dual filters, triple filters, etc. manufactured using cellulose acetate fiber tow containing additives such as activated carbon for removing harmful substances from tobacco smoke ( (shown in Figure 1) is used as a cigarette smoke filter. This cellulose acetate fiber for cigarette smoke filters contains 0.5 to 1.5 titanium white, etc.
wt% is added. The reason for adding titanium white is mainly to whiten the smoking mouth of cigarette smoke filters that use cellulose acetate fiber tow.This whiteness gives smokers a sense of cleanliness and increases the commercial value of filter cigarettes. is increasing.

This whiteness is unnecessary.

優れていることを見い出し本発明をなすに至った。(Means for Solving the Problem) In view of the above, the inventors of the present invention have conducted research on the production of cellulose acetate fibers to which no titanium white or the like is added, and the tobacco smoke filters made from the same. , found that the absence of additives such as titanium white was effective in reducing the filtration process and the friction and wear in the fiber guide process.Furthermore, cigarette smoke filters have a lower tar content than titanium white-added filters. Although the filtration performance for nicotine content is the same, the present inventors have discovered that the aroma and taste are superior.

ト繊維ヲ得ることが出来る。The cellulose acetate fibers used in the present invention can be produced by known methods, but those obtained by dry spinning from a hydrous acetone solution are particularly preferred. When cellulose acetate is dissolved in hydrated acetone, a spinning solution is prepared without adding any pigments such as titanium white, and cellulose acetate fibers containing no titanium white can be obtained by dry spinning.

ィルターも同様にして公知の方法で作ることが出来る。The cellulose acetate fibers thus obtained, which do not contain titanium white, are opened, a binder such as triacetin is added thereto, and the fibers are rolled up into a cylindrical shape. Also, a filter to which an adsorbent such as activated carbon is added can be similarly produced by a known method.

It can be made by filling the space provided in the

した。Tar removal rate and nicotine removal rate are determined by attaching a filter tip to a cigarette and smoking, and quantifying the amount of nicotine and tar in the smoke that passed through the filter and captured by the filter using liquid chromatography and gravimetry, respectively. The respective proportions captured in the samples are shown in weight %.

Use as spinning stock solution. Usually, 0.5 to 1.0% of titanium is added during melting.
Although 5 wt% is added, it is not added in the present invention. At this time, a difference in filtration pressure was observed depending on whether or not titanium was added, and in the case where titanium was not added, it was possible to reduce the filtration process.

A filter plug with a circumference of 24.7% was produced by cutting to a size of 102×.

の減少は製造作業の効率化を図ることができる。Table 1 This result is due to the fact that when titanium white etc. are not included, the strength and elongation of the cellulose acetate fibers are improved, the surface smoothness is improved, and the frictional resistance in the plug manufacturing machine is reduced. In the filter plug manufacturing process, the reduction of fuzz can improve the efficiency of manufacturing operations.

喫味良好とする人が多かった。Furthermore, this filter plug was cut into pieces of 17 to 17 mm, and the ventilation resistance and fiber filling amount when used as a tobacco smoke filter were measured. Next, a part of the filter of a commercially available cigarette "Long Piece" (trade name) was completely removed, and the filter manufactured by the above method was installed in its place, and the nicotine and tar removal rate and flavor were measured. . Table -
2 shows the results. As is clear from this table, when the airflow resistance of the chip and the filling amount of tow are the same, the removal rate of nicotine and tar is almost the same, but the tobacco smoke filter made from fibers that do not contain titanium white has a good flavor and taste. There were many people who said that.

We adjusted the length to the same length, set up a precise device, and tested the aroma and taste of cigarettes. The results are shown in Table-3. From Table 3, it is recognized that the cigarette smoke filter made from cellulose acetate that does not contain titanium white improves the aroma and taste.
