200916001 九、發明說明： 【發明所屬之^技術領域迴 本發明有關用於製造含有再製纖維素之於草煙霧滤嘴 的方法。 5 【先前技術】 菸草煙霧濾嘴，特別是用於香煙者，典型上係由醋酸 纖維酯製造。用於進一步製造的起始材料為捲曲連續細絲 纖維之醋酸纖維酯的絲束（見例如WO 2007/026131 A1)，絲 束通常以一大捆的形式供應。於濾嘴機器之區域為進一步 1〇加工之過程中，絲束由大捆中拉出且打開。打開，也稱作“拉 伸或抽出，發生於拉伸系統中。加工時，材料變鬆且變 大但同日守保持捲曲的基礎結構且橫切為個別的纖維。打開 的絲束形成為濾嘴條且被包覆物圍繞，其後切成一定尺寸 並包裝或直接前送至香煙機器。 15 由再製纖維素組成的菸草煙霧濾嘴亦為已知。再製纖 維素材料為乾濕饋出製程（溶劑紡織製程）中製造而成之纖 維素纖維及細絲纖維素材料。例如，us 4246221描述萊赛 洛(lyocell)纖維的製造。基於纖維素之相似的饋出纖維以黏 液纖維及莫代爾（modal)纖維之名為眾所皆知。 yr\ DE 10〇53359 A1描述製造纖維素物件(例如由萊賽洛 組成之纖維或細絲）的方法，其中提供具有吸附劑（例如活化 碳）的紡織溶液。此種材料可被用於製造菸草煙霧濾嘴，其 對氣態物質展現特別受歡迎的保持特性。 捲曲之萊賽洛連續細絲纖維的絲束已經知道（w〇 5 200916001 95/24520 A1)，但是因為其等之黏彈纖維性質不同於由醋酸 纖維酯組成之捲曲連續的細絲纖維(較高破裂強度，較低破 裂延展性），所以迄今仍未被用作濾嘴製造的起始材料。這 暗示著要在為醋酸纖維酯連續細絲纖維組成之絲束所設計 5 的濾嘴機器中打開這些絲束可能還是有問題。所以，迄今 未知可於慣常的濾嘴機器上加工，包括再製纖維素之菸草 煙霧濾嘴反而係由短纖維不織布製造，但這無法在慣常濾 嘴機器上完成且通常較貴也不方便。 原則上，再製纖維素是菸草煙霧濾嘴非常合適的材 10 料，因為纖維素可比醋酸纖維酯更快地於環境中降解，且 藉著例如吸附劑之添加（見上述)可更加地符合規定的性質。 【發明内容3 本發明的目標為提供一種製造再製纖維素菸草煙霧濾 嘴的方法，其既不昂貴又容易加入製造操作過程中且可以 15 使用用於製造醋酸纖維酯濾嘴條的機器。 此目標可藉一種具有申請專利範圍第1項特徵之製造 菸草煙霧濾嘴的方法而達成。本發明優點之詳細闡述從申 請專利範圍附屬項可更加地顯明。申請專利範圍第22項關 於一種藉由本發明支方法所得的菸草煙霧濾嘴，申請專利 20 範圍第23項為一稚包括此種菸草煙霧濾嘴的濾嘴香煙。 在本發明製造包括再製纖維素之菸草煙霧濾嘴的方法 中，包括再製纖維素之濾嘴材料的絲束被捲曲及其後立刻 地被打開。 此處“絲束”應解為非常普通的意義，即許多個別纖維 200916001 之繩索，沒有整個橫切或是其形狀沒有特別地特定。絲束 之纖維/又被扭轉且於捲曲前通常為平行對齊地排列。 ㊉在本毛月方/去中，遽嘴材料之絲束為捲曲的，所以不 f要播㈣起始材料。已齡人驚#地知道，與流行觀點 尸反的&括再製纖維素之渡嘴材料絲束可被有效率地打 1如此在捲曲後可以在用於製造醋酸纖維醋遽嘴的渡嘴 機器上執行進—步的據嘴製造過程。 於本發月之一有利的實施例中，絲束在捲曲前可從數 固個別絲束中收合。至少兩個個別絲束可具有不同之組 戍。如此提供了使用相當少數不同種類之個別絲束，例如 ^此添加物(諸如吸_)不同及/或雜黯不同來組合 =數不同種類之料煙魏嘴的可能性。此種方法因此在 梅作上非常具有彈性。 然而，用於收合絲束之個別絲束也可具有相同的結 構。所以’從—開始就僅使用單-絲束也是可以想像的。 個別絲束的總線性密度為例如從丨〇〇〇 dtex至25〇〇〇 dtex的範圍，較佳地從3〇〇〇dtex至12〇〇〇dtex的範圍，然而 吹5絲束之總線性密度可為例如從丨5〇〇〇 dtex至8〇〇〇〇 dtex 的fe圍。當濾嘴材料包括由再製纖維素組成之連續的細絲 織維時，由再製纖維素組成之連續的細絲纖維之個別線性 衝度為例如從1 ·5 dtex至12 dtex的範圍。 有用的再製纖維素包括已知材料，諸如萊賽洛纖維、 勒液纖維及莫代爾纖維。相同地，此等材料之混合物也是 可以想像的。 200916001 如已經提及者，渡嘴材料可包括至少一個吸附劑，例 如活化碳、離子交換劑、氧化紹、二氧切等等。吸附劍， 例如以粒狀形核以粉狀形式，可混合成為出現於纺織溶 液中之再製纖維素的起始材料，使得載有吸附劑之再製纖 維素纖維可被饋出，例如插述&dei_359 ai^e

如已經指出者’捲曲之後的步驟(特別是打開、形成條 15狀、以據嘴包覆紙包覆、切割及包裝）可以在商業上可取得 之渡嘴條機器，例如HauniMaschinenbauAG公司上市名為 KDF”的濾嘴條機器上執行。在打開步驟後，接著打開之 後的步驟也於此機器中執行。 如原則上已知者，捲曲步驟發生於填匣中。打開步驟 2〇執行於拉伸系統中。於此連接之一有利的實施例中，填匣 與拍1伸系統之間置有一緩衝器用以使填匣之間歇操作適合 拉伸系統之連續操作。 當絲束捲曲前從數個個別絲束收合時，備置於心軸上 之個別絲束可被用於此種目的。 200916001 捲曲後，當添加物（如已提及者例如粒狀、粉狀或糊 狀、液狀)施加至絲束（或引入絲束）時，此係較佳地發生於 打開之後。例如藉助喷霧室施加液體，其中至少一部份的 添加物係藉著喷霧施加，且例如固體係藉著分散裝置施 5 加。當粒狀加入時，達到包括再製纖維素之絲束之起始重 量的三倍的載重是可能的。 就用於菸草煙霧濾嘴而言，再製纖維素具有超過醋酸 纖維酯的優點。不需要諸如固化劑或塑化劑（特別是三乙醯 甘油）的添加物。更且，再製纖維素加工時比醋酸纖維醋較 10 不會產生灰塵。所以，依據本發明之方法具有經濟上之優 點，包括例如萊赛洛纖維的價格相當於或事實上低於醋酸 纖維酯的事實。 更且，依據本發明之方法，允許以各種可能的變化方 式從具有不同組成物、不同總線性密度或不同添加物材料 15 (諸如吸附劑或吸附劑混合物）之個別絲束來組合濾嘴材料 的絲束。庫存成本因此是較受歡迎的。捲曲的程度可直接 地控制，即可以變化而不需依賴供應者的苛刻協定（如於醋 酸纖維酯之捲曲絲束的事例中）。 本發明現將參考操作實例進一步描述。第1圖顯示實行 20 本發明之方法的簡要描述。

Description of the Invention: [Technical Field] The present invention relates to a method for producing a grass smoke filter containing reconstituted cellulose. 5 [Prior Art] Tobacco smoke filters, especially for cigarettes, are typically made from cellulose acetate. The starting material for further manufacture is a tow of cellulose acetate ester of crimped continuous filament fibers (see for example WO 2007/026131 A1), which are usually supplied in a large bundle. During the further processing of the filter machine, the tow is pulled out of the large bundle and opened. Opening, also referred to as "stretching or drawing, occurs in a stretching system. During processing, the material becomes loose and large but remains the same under the same day and is cut into individual fibers. The opened tow is formed into a filter. The mouth strip is surrounded by a wrap, which is then cut to size and packaged or sent directly to the cigarette machine. 15 A tobacco smoke filter consisting of reconstituted cellulose is also known. The reconstituted cellulosic material is dry and wet. Cellulose fibers and filament cellulosic materials produced in a process (solvent textile process). For example, us 4246221 describes the manufacture of lyocell fibers. Cellulose-like feed fibers are based on mucilage fibers and modal. The name of the modal fiber is well known. yr\DE 10〇53359 A1 describes a method of making a cellulosic article, such as a fiber or filament composed of lyocell, provided with an adsorbent (eg, activated carbon). Textile solution. This material can be used to make tobacco smoke filters, which exhibit a particularly desirable retention characteristic for gaseous materials. The tow of the crimped Lexelo continuous filament fiber is known (w 〇5 200916001 95/24520 A1), but because its viscoelastic fiber properties are different from crimped continuous filament fibers composed of cellulose acetate (higher burst strength, lower rupture ductility), it has not been Used as a starting material for the manufacture of filters. This suggests that it may still be problematic to open these tows in a filter machine designed for tows composed of cellulose acetate continuous filament fibers. Conventional filter machines, including reconstituted cellulose smoke filters, are made of staple fiber nonwovens, but this cannot be done on conventional filter machines and is generally more expensive and inconvenient. In principle, reconstituted cellulose is tobacco. The smoke filter is a very suitable material because cellulose can degrade faster in the environment than cellulose acetate, and can be more conformed to the specified properties by, for example, the addition of an adsorbent (see above). It is an object of the invention to provide a method of making a reconstituted cellulose tobacco smoke filter that is neither expensive nor easy to incorporate into the manufacturing process and can be used 15 Machine for the manufacture of a cellulose acetate filter strip. This object can be achieved by a method for producing a tobacco smoke filter having the features of claim 1 of the patent application. The advantages of the invention are explained in more detail from the scope of the patent application. It is obvious that the scope of claim 22 is related to a tobacco smoke filter obtained by the method of the present invention, and the scope of claim 23 is a filter cigarette including a tobacco smoke filter. In a method of cellulose tobacco smoke filter, a tow comprising a filter material of reconstituted cellulose is crimped and immediately opened. Here, "tow" should be interpreted as a very common meaning, that is, a plurality of individual fibers. The rope of 200916001, without the entire cross section or its shape is not particularly specific. The fibers of the tow are again twisted and are generally aligned in parallel alignment prior to crimping. Ten in the Maoyue side/go, the tow of the pout material is curled, so it is not necessary to broadcast (iv) the starting material. It’s age-aware. It’s known that the tow of the re-made cellulose with the popular view of the corpse can be efficiently beaten so that it can be used in the manufacture of the mouth of the acetate vinegar The step-by-step manufacturing process is performed on the machine. In one advantageous embodiment of the present month, the tow can be folded from a plurality of individual tows prior to crimping. At least two individual tows can have different sets of turns. This provides the possibility to use a relatively small number of different types of individual tows, such as ^this additive (such as suction_) and/or miscellaneous to combine = several different types of soot. This method is therefore very flexible in the art. However, the individual tows used to fold the tow may also have the same structure. So it is imaginable to use only single-tows from the beginning. The bus density of individual tows is, for example, in the range from 丨〇〇〇dtex to 25 〇〇〇dtex, preferably in the range from 3 〇〇〇dtex to 12 〇〇〇dtex, whereas the bust of the 5 tow is blown. The density can be, for example, from 丨5〇〇〇dtex to 8〇〇〇〇dtex. When the filter material comprises a continuous filament web composed of reconstituted cellulose, the individual linear improvities of the continuous filament fibers consisting of the reconstituted cellulose are, for example, in the range from 1 · 5 dtex to 12 dtex. Useful reconstituted celluloses include known materials such as lyocell fibers, Leroy fibers, and modal fibers. Similarly, mixtures of such materials are also conceivable. 200916001 As already mentioned, the nozzle material may comprise at least one adsorbent, such as activated carbon, ion exchanger, oxidized, dioxane, and the like. The adsorption sword, for example, in the form of a powdery nucleus in powder form, can be mixed into a starting material of the regenerated cellulose present in the textile solution, so that the reconstituted cellulose fiber carrying the adsorbent can be fed out, for example, insert &;dei_359 ai^e 19917614A1. Alternatively or additionally, the agent may also be introduced into the fibers of the filter material, '(4) and/or fibers applied to the filter material with or without the addition of a bonding sword. Preferably, after crimping and opening, the tow is formed as a mouthpiece surrounded by the wrap. It is possible to use coated paper and glue on the market. Thereafter, the nozzle strip around the wrapper can be cut to a predetermined length (e.g., various lengths of individual grass mist nozzles) and packaging. It is also conceivable that the filter rod is sent directly to the cigarette machine. As already indicated, the steps after the crimping (especially opening, forming strips 15, wrapping, cutting and packaging according to the mouth coated paper) can be commercially available as a nozzle machine, such as the name of HauniMaschinenbau AG. The KDF" filter strip is executed on the machine. After the opening step, the subsequent steps after opening are also performed in this machine. As is known in principle, the crimping step takes place in the filling. Opening step 2 is performed in stretching In an advantageous embodiment of the system, a buffer is provided between the filling and the stretching system for adapting the intermittent operation of the filling to the continuous operation of the stretching system. Individual tows placed on the mandrel can be used for this purpose when individual tows are folded. 200916001 After crimping, when added (as mentioned, for example, granular, powdery or pasty, liquid) When applied to the tow (or introduction of a tow), this preferably occurs after opening. For example, a liquid is applied by means of a spray chamber, wherein at least a portion of the additive is applied by a spray, and for example a solid Disperse The device is applied in 5. When the granules are added, it is possible to reach a load of three times the initial weight of the tow comprising the reconstituted cellulose. For the tobacco smoke filter, the reconstituted cellulose has more than the cellulose acetate. Advantages: Additions such as curing agents or plasticizers (especially triethylene glycerol) are not required. Moreover, no more dust is produced when the cellulose is processed than cellulose acetate vinegar. Therefore, the method according to the invention It has economic advantages, including, for example, the fact that the price of the lyocell fiber is equivalent to or is actually lower than that of the cellulose acetate. Moreover, the method according to the invention allows for different compositions from different possible variations. The individual density of the bus density or different additive materials 15 (such as adsorbent or sorbent mixture) combines the tow of the filter material. The inventory cost is therefore more popular. The degree of curl can be directly controlled, ie The change does not depend on the supplier's harsh agreement (as in the case of crimped tow of cellulose acetate). The invention will now be further described with reference to the operational examples. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 shows a brief description of the practice of the present invention. Figure 1 is a simplified illustration of an example of how the process for making a tobacco smoke filter comprising reconstituted cellulose can be carried out. Part, namely the combination device 1, the crimping machine 2, the stretching system 3 and the normalization device 4. 9 200916001 The grass smoke nozzle is composed of various materials in the operation example. For this purpose, the combination device 1 has many Mandrels (wefts, reels) ιο, each mandrel is wound with individual tows 12. For example, individual tows 12 are composed of purely formless Lysellow's non-crimped continuous filament fibers or mixed groups In principle, all groups of individual tows 12 are of the same type and are conceivable. The operating examples are described below. Individual tows 12 (each having, for example, a bus density from 3 〇〇〇 The range of 12000 dtex is collapsible in the funnel-type collet 14 to form a tow 16 having, for example, a bus density ranging from 25,000 edges to 80 〇〇〇dtex. Combination device! It is thus possible to provide a filter material tow 16 which is individually selected from the components in the form of individual wire corrections. 15 The bundle 16 containing, for example, continuous Leycero filament fibers which are normally maintained without curling is then fed into the crimper 2. The crimping machine 2 is in principle a conventional design, but is conventionally placed upstream of the filter and nozzle making machine (4) because the front crimped tow is the starting material in the prior art. The tow is curled in the fill (4), which has the original straightforwardness of the ancients. The individual fibers of the financial H material towel are folded into a curly, ore-toothed structure, ^ as required by the grass smoke filter. In the example of staying in the case, a piston moves in the S18 to make a rest operation. Therefore, a buffer 20 is placed downstream of the fill gl8 to accept the curl #16 and is made available for continuous operation. ^ ", % continues to occur downstream of the buffer 20. Further, not depicted in the first Figure--, 'Yecheng can be placed upstream of the filling 18 to affect the predetermined temperature and / or humidity of the field +, fruit. With this, to improve the curled knot from the buffer 20 to leave the curled wire ... 6 through the extension of the steel mold 22 linear 20 200916001 into the tensile system 3. In the stretching system 3, through the tow between the two brake rolling mill 24 is fed into the pair of stretch rolling mill 2 For example, in two places, the pair of rolling mills 26b operate at a higher speed than the other pair of rolling mills 26a, causing the tows 6 to open while maintaining the crimped base structure of the individual fibers. The properties of the elastic fibers are different from those of cellulose acetate, and the crimped tow 16 including the reconstituted cellulose is efficiently opened. The second to the downstream of the stretching and lighter machine 26, which is placed in the fine example, wherein the tow 16 is opened May be associated with additives such as liquids (including substances dissolved or dispersed in them) The tow 16 is assumed to be in the form of a strip after passing through the retarder steel mold 10 22 and the brake rolling mill 24. The adhesive additive is used to fix the powder or particulate matter. The flat tow 16 is then passed through the inlet steel. The die 3 passes through the normalization device 4. An inlet finger 32 is used to form the tow 16 into the filter rod 34 having a substantially circular cross-section. The filter bag is removed from the spool drum. The cover 15 paper 38 is placed around the filter strip 34 via the normalized strip 36, and finally glued together along the resulting longitudinal seam. The cutting device 4 切割 cuts the covered beak strip into segments, most of which These segments are each packaged together. In this example of operation 'these segments have the length of four individual filters. Some examples below show various possibilities for the composition of the tow 16. Among them 20 yarns (linear density) The international customary unit "decitex,, (dtex) represents; 1 dtex = 1 g / l 〇〇〇〇 m. It can be converted to the old unit denier(den) via 1〇 dtex = 9 den. Figure 1 shows schematically a method for making a tobacco smoke filter comprising reconstituted cellulose. 11 200916001 [He 1 brigade * cold type] Example 1 Five individual 'bundles (tow bands), each tow has a bus density of 6660 dtex and each tow has a unique linear density of 5 dtex Luo 5 continuous filament fiber composition, 30% by weight of coconut shell carbon is added during the manufacturing process, "the bust density of the mother bundle is 6660 dtex and the individual linear density is 5 dte X of Lécelo continuous filament fiber Three individual tows (without adsorbent) are drawn from the mandrel (weft, reel) and folded to form a tow with a bus density of 53280 dtex, which is fed directly into the stretching system of the filter machine The top 10 swimmers are filled in. Example 2 Each of the three Lexelon continuous filament fibers with a bus density of 6660 dtex and an individual linear density of 1.7 dtex has a respective bus density of 6660. The individual tows of the three texels and the linear density of 5 dtex are folded to form a Ley-Loss bundle without the addition of an absorbent and having a bus density of 39,960 dtex. The bundle is directly fed into the filter machine The crimping machine upstream of the extension system is filled in. Example 3 A wire bundle with 2 tex of continuous filament fiber with a bus density of 66600 dtex is taken from the drum and fed directly into the roll upstream of the stretching system of the filter machine. The machine is filled in. In this example, the tow is not formed by a combination of several individual tows. Example 4 Each of five individual tows having a bus density of 6660 dtex, the 12 200916001 tow is contained in the fiber 30% by weight of activated carbon and consisting of Lexelo continuous filament fibers with an individual linear density of 5 dtex. Each bus density is 6660 dtex five individual tows containing 30% by weight of the fiber The ion exchanger and the individual linear density of 5 dtex of Lyracuse continuous filament 5 fibers. The two kinds of the above five individual tows are folded together and directly fed into the upstream of the stretching system of the filter machine. Machine filling.
