従来、 この種のフィルタとして、 例えばセルロース系の繊維を束ねた束状体で 構成されたものが知られている。 喫煙者がこれらのフィルタを介してタバコ煙を 吸い出すことで、 タール類等を取り除いたタバコ煙が得られる。  Conventionally, as this kind of filter, for example, a filter formed of a bundle of cellulosic fibers is known. Smokers exhale tobacco smoke through these filters, so that tar and other substances can be removed.
しかしながら、 上述した従来のフィルタでは、 タール類の除去性能が不十分で あった。 この性能を向上させるためには、 フィルタ中における繊維の密度を大き くすることが考えられるが、 それでは、 喫煙者がタバコ煙を吸い出す際の抵抗を 著しく増大させてしまうことや、 タバコ煙に含まれる必要な成分までもフィルタ に吸収されてしまうこととなり、 快適な喫煙ができなくなってしまうという欠点 があった。 発明の開示  However, the conventional filters described above have insufficient tar removal performance. In order to improve this performance, it is conceivable to increase the fiber density in the filter, but this would significantly increase the smoker's resistance to exhaling cigarette smoke, and would also include Even the necessary components to be absorbed are absorbed by the filter, and there is a disadvantage that comfortable smoking cannot be performed.

このように、 タバコフィルタ用セラミックを製造することで、 タール除去性能 に優れたセラミックを製造できる。 発明を実施するための最良の形態 By manufacturing ceramics for cigarette filters in this way, tar removal performance Excellent ceramics can be manufactured. BEST MODE FOR CARRYING OUT THE INVENTION
以下、 本発明の実施形態を説明する。  Hereinafter, embodiments of the present invention will be described.
<第 1実施形態 >  <First embodiment>
図 1は本実施形態に係るフィルタ付き卷紙タバコ（以下 rフィルタ付きタバコ」 という） 1であって、 前部にはタバコの葉をタパコ用卷紙で巻き付けて構成され るタバコ部 2が設けられ、 タバコ部 2の後方にはフィルタ 3が連設されている。 フィルタ 3は、 喫煙者の口元側の第 1フィルタ部 4と、 第 1フィルタ部 4とタ パコ部 2との間に配された第 2フィルタ部 5とを備え、 外周をフィルタ用卷紙に 巻き付けられてなる。  FIG. 1 shows a cigarette with a filter (hereinafter, referred to as r-filtered cigarette) 1 according to the present embodiment, and a cigarette part 2 formed by winding tobacco leaves with a tapaco wrapping paper is provided at the front. A filter 3 is provided behind the tobacco section 2. The filter 3 includes a first filter section 4 on the mouth side of the smoker, and a second filter section 5 disposed between the first filter section 4 and the tapako section 2. It is wound.
第 1フィルタ部 4は、 セルロース系繊維を集束させて形成されており、 口元側 の端部を図示しない喫煙者によって垤えられて、 ここからタバコ煙が吸い出され る。  The first filter section 4 is formed by bundling cellulosic fibers, and the end on the mouth side is caught by a smoker (not shown), from which tobacco smoke is sucked out.
さて、 第 2フィルタ部 5は、 第 1フィルタ部 4同様、 セルロース系繊維を集束 させて形成されると共に、 次述するようにして製造されたセラミックの粉粒体が 添加される。  Now, the second filter section 5 is formed by bundling cellulosic fibers similarly to the first filter section 4, and a ceramic powder produced as described below is added.
セラミックは、 原料としてフライアッシュ、 粘土、 二酸化チタン、 酸化鉄、 及 ぴバインダー樹脂等を用いる。  Ceramics use fly ash, clay, titanium dioxide, iron oxide, binder resin, and the like as raw materials.
ここで、 フライアッシュは、 例えば火力発電所の石炭灰の微粉末を用いて原料 混合物に対して 3 0〜7 0重量％となるように配合することが好ましい。 また、 フライアッシュの代わりに火山灰を用いても良い。 粘土は例えば陶芸用のものを 原料.混合物に対して 2 0〜 6 0重量％となるように配合することが好ましい。 フ ライアッシュ及び粘土を前記の組成範囲内とすることにより、 セラミックが多孔 質となると共に、 十分な硬度を備えることができる。  Here, the fly ash is preferably blended using, for example, a fine powder of coal ash from a thermal power plant so as to be 30 to 70% by weight based on the raw material mixture. Also, volcanic ash may be used instead of fly ash. The clay is preferably used, for example, for pottery purposes in a proportion of 20 to 60% by weight based on the raw material mixture. By setting the fly ash and the clay within the above-described composition range, the ceramic becomes porous and can have sufficient hardness.
酸化チタンは、 原料混合物に対して 1 0〜2 0重量％となるように配合する。 酸化チタンは還元雰囲気で焼成されることにより、 単体に還元され、 セラミック の多孔質中に存在することで、 タバコ煙のタール成分を選択的に吸着することが できる。 前記の組成範囲を超えると多孔質でなくなり、 少ないと選択性に劣るも のとなつてしまう。 Titanium oxide is blended in an amount of 10 to 20% by weight based on the raw material mixture. Titanium oxide is reduced to a simple substance by firing in a reducing atmosphere, and is present in the porous material of the ceramic, so that the tar component of tobacco smoke can be selectively adsorbed. it can. If it exceeds the above-mentioned composition range, it will not be porous, and if it is too small, it will have poor selectivity.
酸化鉄は、 例えば、 ベンガラを用いて原料混合物に対して 5〜1 0重量％とな るように配合する。 酸化鉄は、 還元雰囲気での焼成により金属鉄の単体に還元さ れ、 微粉末とすることによりタールを効率よく吸着させることができる。 伹し、 酸化鉄の配合量が多すぎるとタバコ煙の香り等も吸着してしまうので味覚が低下 してしまう。  The iron oxide is blended using, for example, red iron oxide so as to be 5 to 10% by weight based on the raw material mixture. The iron oxide is reduced to a simple substance of metallic iron by firing in a reducing atmosphere, and can be efficiently adsorbed to tar by making it into a fine powder. On the other hand, if the amount of iron oxide is too large, the odor of tobacco smoke is also adsorbed and the taste is reduced.
パインダ一樹脂としてはフエノール樹脂の粉末が最適である。 パインダ一樹脂 の添加量は、 バインダー樹脂中の炭素が焼成品に残留するから、 その残留炭素量 が焼成品の 5〜2 0重量％となるように計算して決定すればよい。 目標の炭素量 を全てパインダ一樹脂起源とするとパインダ一樹脂の添加量が過剰となって混練 や成形上等の他の不都合な問題を生ずる場合には、 バインダ一樹脂の添加量を抑 え、 その分の炭素を木炭粉末の添加で補えばよい。 また、 製造後のセラミック中 に含まれる炭素量が多いともろくなり、少ないと磁器のように硬くなってしまう。 これらの原料の粉末を、 水と共に混練し、 所定の形状に成形し、 常温で十分に (例えば数日間） 乾燥させた後、 焼成炉に入れ、 窒素ガスを吹き込むことで還元 雰囲気として焼成を行う。 このとき、 焼成温度 3 0 0 で 1時間保持してから、 還元雰囲気のまま、 さらに 8 0 0 °Cで 3時間保持する。 そして、 その後、 自然放 冷することによってセラミックの製造が完了する。  As the binder resin, phenol resin powder is most suitable. Since the carbon in the binder resin remains in the fired product, the amount of the pinda resin added may be determined by calculating such that the residual carbon amount is 5 to 20% by weight of the fired product. If the target carbon content is all derived from binder-resin, if the amount of binder-resin added becomes excessive and causes other inconvenient problems such as kneading or molding, the amount of binder-resin should be reduced. That carbon can be supplemented by adding charcoal powder. Also, if the amount of carbon contained in the ceramic after production is high, it becomes brittle, and if it is low, it becomes hard like porcelain. The powders of these raw materials are kneaded with water, formed into a predetermined shape, dried sufficiently at room temperature (for example, for several days), placed in a firing furnace, and fired in a reducing atmosphere by blowing nitrogen gas. . At this time, the temperature is kept at a firing temperature of 300 for 1 hour, and then kept at 800 ° C. for 3 hours in a reducing atmosphere. Then, the ceramic is completed by allowing it to cool naturally.
第 2フィルタ部 5には、 上記のようにして製造されたセラミックを粉砕して得 られた粉粒体を、 繊維に絡み合うようにして、 第 2フィルタ部内に均一に分布す るように添加される。  The granules obtained by pulverizing the ceramic produced as described above are added to the second filter section 5 so as to be entangled with the fibers so as to be uniformly distributed in the second filter section. You.
このようにして本実施形態のフィルタ付きタバコ 1が製造される。  Thus, the filter-fitted tobacco 1 of the present embodiment is manufactured.
上記のように構成されるフィルタ付きタバコ 1に関して、 原料としてフライァ ッシュ、 粘土、 二酸化チタン、 酸化鉄及び、 フエノール樹脂を配合したセラミツ クを用いて第 2フィルタ部 5を形成した実施例 1を製造した。  Regarding the cigarette 1 with a filter configured as described above, Example 1 in which the second filter portion 5 was formed using ceramics containing fly ash, clay, titanium dioxide, iron oxide, and a phenol resin as raw materials was manufactured. did.
実施例 1に用いたセラミックは、 表 1に示す割合で配合して製造した。  The ceramic used in Example 1 was produced by blending at the ratio shown in Table 1.

55 20 10 5 10 この,セラミックを JJ粉枠してフノレイにかけ、 1 0 0メッシュのフノレイに通ったも のを粉末とし、 1 0◦メッシュのフルイを通過せず 5 0メッシュのフルイに通つ たものを顆粒とした。 そして、 粉末或いは顆粒を、 第 2フィルタ部 5に添カ卩した ものそれぞれにっき、 セラミックの添加量を変化させてタールの吸着性能を測定 した。  55 20 10 5 10 This ceramic is JJ powdered and framed and funneled, and what passed through the 100 mesh Funneli is powdered and passed through the 50 mesh screen without passing through the 100 mesh screen. The resulting mixture was made into granules. Then, the powder or granules were added to the second filter section 5 and added to the second filter section 5, and the amount of added ceramic was measured to measure the tar adsorption performance.
測定に用いたフィルタ付きタバコ 1は、 タパコ部 2に市販のフィルタ付きタパ コのタパコ葉を用いたものを用意し、 これに、 直径 8 mmであって、 1 5 mmの 第 1フィルタ部 4と、 1 O mmの第 2フィルタ部 5とを備えた全長 2 5 mmのフ ィルタ部 3を連接して作成したものである。  For the tobacco with a filter 1 used for the measurement, a tapaco part 2 using a commercially available tapaco leaf of a tapaco with a filter was prepared, and a first filter part 4 having a diameter of 8 mm and a diameter of 15 mm was prepared. And a filter section 3 having a total length of 25 mm and a second filter section 5 of 1 O mm.
実際の測定は、 フィルタ付きタバコ 1に点火し、 吸口側からタバコ煙を吸い出 して得られるタバコ 1本分のタバコ煙中に含まれるタールの質量を計測すること により行った。 結果を表 2に示す。  The actual measurement was performed by igniting the cigarette 1 with a filter and measuring the mass of tar contained in one cigarette smoke obtained by sucking out the cigarette smoke from the mouth side. Table 2 shows the results.
尚、 表 2には、 比較例 1及ぴ 2を記載した。 ここで比較例 1は、 市販フィルタ をそのまま取り付けたタバコの吸口側から排出させたタパコ煙の測定結果であり、 比較例 2は、 市販のフィルタ付きタバコのフィルタ部分を切除して、 フィルター を介さずに排出させたタバコ煙についての測定結果である。  Table 2 shows Comparative Examples 1 and 2. Here, Comparative Example 1 shows the measurement results of tapako smoke discharged from the mouth of a cigarette to which a commercially available filter was directly attached. It is the measurement result about the tobacco smoke discharged | emitted.

比較例とのタール除去率の比較からも明らかなように、 実施例 1は、 タールの 除去性能に優れている。 そして、 タールの除去性能はセラミックの粉粒体の添カロ 量に比例して向上する。
Figure imgf000008_0001
As is clear from the comparison of the tar removal rate with the comparative example, Example 1 is excellent in tar removal performance. The tar removal performance is improved in proportion to the amount of added calo in the ceramic powder.
また、 表 2には、 タパコ煙中に含まれるニコチン量について、 ガスクロマトグ ラフで測定した結果も記載した。 これらの結果から、 タールの減少した割合に比 ベてニコチンの減少した割合は相対的に小さいので、 本実施形態のフィルタ付き タバコが、 タールを選択的に吸着していることが判明した。 Table 2 shows the amount of nicotine contained in tapako smoke by gas chromatography. The results of rough measurements are also described. From these results, it was found that the rate of decrease in nicotine was relatively smaller than the rate of decrease in tar, so that the tobacco with a filter of the present embodiment selectively adsorbed tar.
このように本実施形態のフィルタ付きタバコ 1によれば、 セラミックを含有す ることで、 タパコ煙中のタール類を吸着するので、 喫煙者がタバコ煙を吸い出す 際の抵抗や、 'タバコ煙中の必要な成分がフィルタに吸収される量の著しい増大を 伴なうこと無く、 タールの除去性能を向上させることが可能となった。 また、 タ ールを選択的に除去することで、 有効成分であるニコチンの量を同等に保持しつ つタバコ煙自体を減少させることが可能となった。  As described above, according to the filter-fitted cigarette 1 of the present embodiment, the inclusion of the ceramics allows the tars in the tapaco smoke to be adsorbed. It is possible to improve the tar removal performance without significantly increasing the amount of the component required for the absorption by the filter. In addition, by selectively removing tar, it was possible to reduce the amount of tobacco smoke itself while maintaining the same amount of nicotine as the active ingredient.
実施例 1のように、 第 2フィルタ部 5がセラミックを含有することでタールの 除去性能が発現される、 タールの除去性能をより一層向上させたい場合には、 セ ラミックを 1 O m g以上含有させればよい。  As in the first embodiment, tar removal performance is exhibited by the second filter section 5 containing ceramic. To further improve the tar removal performance, the ceramic contains 1 mg or more of ceramic. It should be done.
さらに、 粉粒体が第 2フィルタ部 5內の繊維に絡み合って配されているので、 粉粒体が、 第 2フィルタ部 5からはみ出ることが制限されると共に、 粉粒体が微 量であっても第 2フィルタ内において均一に分布させる'ことができる。  Further, since the particles are entangled with the fibers of the second filter section 5 內, the particles are prevented from protruding from the second filter section 5 and the amount of the particles is small. Even in this case, they can be uniformly distributed in the second filter.
また、 本実施形態のようにフィルタ部 3を第 1フィルタ部 4と第 2フィルタ部 5との 2層構造とし、 セラミックの粉粒体は、 吸い口と反対側に配された第 2フ ィルタ部 5に配合されているので、 仮に、 喫煙中に粉粒体が吸い口側に移動して 第 2フィルタ部 5からはみ出てしまった場合でも、 第 1フィルタ部 4でその移動 を食い止めることができ、 粉粒体が吸い口から喫煙者の口腔内へ侵入するといつ たことが無い。 従って、 快適な喫煙が可耜となる。  Further, as in the present embodiment, the filter unit 3 has a two-layer structure of the first filter unit 4 and the second filter unit 5, and the ceramic powder is formed by the second filter disposed on the side opposite to the suction port. Since it is contained in part 5, even if the granular material moves to the suction side and protrudes from the second filter part 5 during smoking, the movement can be stopped by the first filter part 4. Yes, there is no chance that particulate matter will enter the mouth of a smoker through the mouthpiece. Therefore, comfortable smoking is possible.
