Description
本発明は分解可能なシガレットフィルタに関し、より詳細には、分解可能な材料でできた加工繊維、及びシガレットフィルタにおけるこのような加工繊維の使用に関する。 The present invention relates to degradable cigarette filters, and more particularly to processed fibers made of degradable materials and the use of such processed fibers in cigarette filters.
従来のシガレットフィルタプラグは、トリアセチンにより互いに接合したセルロースアセテート繊維から作られている。喫煙後、使用済みのフィルタは環境内に廃棄されることがある。その中のセルロースアセテートフィラメントは、タバコ及び／又はシガレットのペーパー部分よりもゆっくりと分解する傾向にあり、環境内のゴミの一因となることが多い。このようなゴミを減らすために、シガレットフィルタ内のセルロースアセテートフィラメントを環境内でセルロースアセテートよりも速く分解する材料に置き換える必要性が存在する。同時に、セルロースアセテートトリアセチン系から得られる濾過親和力、煙特性、消費者の受容性を保持する必要性も存在する。 Conventional cigarette filter plugs are made from cellulose acetate fibers joined together by triacetin. After smoking, used filters may be discarded into the environment. The cellulose acetate filaments therein tend to degrade more slowly than the paper portion of tobacco and / or cigarettes and often contribute to garbage in the environment. In order to reduce such debris, there is a need to replace the cellulose acetate filament in the cigarette filter with a material that degrades faster in the environment than cellulose acetate. At the same time, there is a need to retain the filtration affinity, smoke characteristics and consumer acceptability obtained from the cellulose acetate triacetin system.
本発明の目的の１つは、計画的断面形状を有する繊維状に形成された生分解性材料から生産されるシガレットフィルタである。 One of the objects of the present invention is a cigarette filter produced from a biodegradable material formed into a fibrous shape having a planned cross-sectional shape.
本発明の別の目的は、表面積を増やすとともにフィルタ当たりの全体的な材料を減らした生分解性加工繊維から成るシガレットフィルタである。 Another object of the present invention is a cigarette filter consisting of biodegradable processed fibers with increased surface area and reduced overall material per filter.
本発明のさらに別の目的は、良好な送達及び選択的濾過のための香味料及び吸着材を保持する微小空洞を内部に有する生分解性加工繊維から成るシガレットフィルタである。 Yet another object of the present invention is a cigarette filter consisting of biodegradable processed fibers having microcavities within which hold flavorings and adsorbents for good delivery and selective filtration.
本発明によれば、生分解性シガレットフィルタがＰＨＢＶの加工繊維を含む。繊維は、Ｙ、Ｖ、Ｃ、Ｔｒｉａｄ、４−ＤＧ、及びＪＣ形状を含む計画的断面形状を有することができる。さらに、加工繊維は、内部に吸着材及び／又は香味料を含む微小空洞を含むことができる。 According to the present invention, the biodegradable cigarette filter includes PHBV processed fibers. The fibers can have planned cross-sectional shapes including Y, V, C, Triad, 4-DG, and JC shapes. Furthermore, the processed fibers can include microcavities that contain adsorbents and / or flavorings therein.
同様の部分が同様の参照文字により特定される添付図面と共に以下の詳細な説明を読むことにより、当業者には、上述の内容に加えて本発明の新規の特徴及び利点が明らかになるであろう。 In addition to the foregoing, the novel features and advantages of the present invention will become apparent to those skilled in the art upon reading the following detailed description in conjunction with the accompanying drawings, in which like parts are identified with like reference characters. Let's go.
本発明のシガレットフィルタは、紙（木材パルプ）、羊毛、アセチル化レベルの低いセルロースアセテート、でんぷん、及びでんぷんベースのポリマ複合材料、綿、ポリ乳酸、ポリビニルアルコール、ポリヒドロキシアルカン酸、ポリエステル、ポリエステルアミド、ポリカプロラクトン、不安定ポリプロピレン、マイクロガラス材料、及びこれらの組み合わせなどの生分解性材料から作られるシート、フィルム、ファイババンド、ヤーン、又は不織布で作ることができる。溶融紡糸、乾燥紡糸、湿式紡糸、電界紡糸、又はその他のあらゆる公知の繊維化工程により、生分解性材料を繊維に紡ぐことができる。 The cigarette filter of the present invention comprises paper (wood pulp), wool, cellulose acetate having a low acetylation level, starch, and starch-based polymer composite material, cotton, polylactic acid, polyvinyl alcohol, polyhydroxyalkanoic acid, polyester, and polyesteramide. Can be made of sheets, films, fiber bands, yarns, or nonwovens made from biodegradable materials such as polycaprolactone, labile polypropylene, microglass materials, and combinations thereof. The biodegradable material can be spun into fibers by melt spinning, dry spinning, wet spinning, electrospinning, or any other known fiberization process.
例えば、ＰＨＢＶ（ポリヒドロキシブチレート−コ−ヒドロキシバレレート）及びＥｃｏｆｌｅｘ、ＰＢＳ（ポリブチレンコハク酸エステル）、ｄ−、１−、及びｄｌ−ＰＬＡ（ポリ乳酸）、及びでんぷん合成物などの、ＰＨＢＶと脂肪族芳香族ポリエステルとのブレンドが、溶融紡糸工程により首尾よく円形断面の繊維に紡がれてきた。しかしながら、表面積を増やすとともにフィルタ当たりの材料の使用を減らすために、本明細書のフィルタ繊維は改良された断面形状を有する。これらの加工繊維がフィルタ状に形成され、ゴミを減らすシガレットで使用される。 PHBV, such as PHBV (polyhydroxybutyrate-co-hydroxyvalerate) and Ecoflex, PBS (polybutylene succinate), d-, 1-, and dl-PLA (polylactic acid), and starch compounds Blends of olefins and aliphatic aromatic polyesters have been successfully spun into fibers of circular cross section by a melt spinning process. However, the filter fibers herein have an improved cross-sectional shape to increase surface area and reduce the use of material per filter. These processed fibers are formed in a filter shape and used in cigarettes that reduce dust.
紡糸工程で使用するダイの形状により、繊維の断面を制御することができる。図１〜図６に示すように、溶融紡糸工程において適正なダイを使用することにより、繊維の断面をＹ、Ｖ、Ｃ、Ｔｒｉａｄ、４−ＤＧ、又はＪＣに変更することができる。米国特許第６，９０７，８９５号における繊維断面などの、文献で報告されてきたその他の繊維断面が引用により本明細書に含まれる。 The cross section of the fiber can be controlled by the shape of the die used in the spinning process. As shown in FIGS. 1-6, the cross section of the fiber can be changed to Y, V, C, Triad, 4-DG, or JC by using an appropriate die in the melt spinning process. Other fiber cross sections that have been reported in the literature, such as fiber cross sections in US Pat. No. 6,907,895, are hereby incorporated by reference.
これらの加工繊維をシガレットフィルタに加工するために、シガレットフィルタ製造工程中に、単一又は複数成分から作られるこれらの加工繊維の単一の又は複数のより糸をトウバンドに巻き込みクリンプするか、或いは高速分解可能材料で作ったこれらの加工繊維のより糸をセルロースアセテート繊維と組み合わせて接合トウバンドを形成することができる。或いは、上記繊維から作られる不織布を、メルトブロー、スパンボンド、ニードルパンチ／フェルト、湿式堆積、空気堆積、及びその他の処理により生産し、その後、転動、折り畳み、又は破砕処理によりシガレットフィルタに加工することができる。硬さ及び煙の主観的調整に必要な場合、フィルタ内の繊維上に適正な量の結合／硬化剤を加えることができる。同様に、炭素粒などの吸着材及びメントールなどの香味料を加工繊維の微小空洞内に含浸することができる。 To process these processed fibers into cigarette filters, during the cigarette filter manufacturing process, single or multiple strands of these processed fibers made from single or multiple components are wound into a tow band for crimping or high speed. These processed fiber strands made of degradable materials can be combined with cellulose acetate fibers to form a bonded tow band. Alternatively, non-woven fabrics made from the above fibers are produced by meltblowing, spunbonding, needle punch / felt, wet deposition, air deposition, and other processes and then processed into cigarette filters by rolling, folding, or crushing processes. be able to. If necessary for subjective adjustment of hardness and smoke, the proper amount of binder / curing agent can be added on the fibers in the filter. Similarly, adsorbents such as carbon particles and flavors such as menthol can be impregnated into the microcavities of the processed fibers.
