本發明涉及一種用於吸菸製品的過濾嘴及包括其的吸菸製品，上述用於吸菸製品的過濾嘴包括：過濾嘴部，包含分散有苯酚類減少物質的萊賽爾絲束；及過濾嘴部包裝紙，圍繞上述過濾嘴部，由具有預定基重以上的範圍且經過耐油處理的卷紙（即，耐油性硬卷紙）形成。The present invention relates to a filter for smoking products and a smoking product including the same. The filter for smoking products includes: a filter portion, including a lyocell bundle in which a phenol-reducing substance is dispersed; and a filter portion wrapping paper, surrounding the filter portion, formed by a rolling paper having a predetermined basis weight range or more and being treated with oil resistance (i.e., oil-resistant hard rolling paper).
一般香菸過濾嘴使用從木漿提取纖維素並乙醯化的醋酸纖維素絲束（tow）。並且，香菸過濾嘴被組裝成吸菸製品，分發給消費者，供吸菸，在吸完捲菸後最終被廢棄。另外，有些香菸過濾嘴可以被香菸過濾嘴製造廠作為製造殘留物直接廢棄。這些香菸過濾嘴廢棄物作為廢物被回收並經過填埋處理。此外，在某些情況下，吸菸後的菸蒂不會作為廢物被回收，而是被遺棄在自然環境中。Generally, cigarette filters use cellulose acetate tow (tow) which is acetylated and extracted from wood pulp. Furthermore, cigarette filters are assembled into smoking products, distributed to consumers for smoking, and finally discarded after smoking the cigarettes. In addition, some cigarette filters can be directly discarded as manufacturing residues by cigarette filter manufacturers. These cigarette filter wastes are recycled as waste and disposed of in landfills. In addition, in some cases, cigarette butts after smoking are not recycled as waste, but are abandoned in the natural environment.
因此，近年來，為了保護自然環境並降低成本，進行以環保材料代替醋酸纖維素絲束的研究。例如，不同於醋酸纖維素，使用通過將纖維素本身纖維化而成的萊塞爾（lyocell）纖維的絲束正在被開發。Therefore, in recent years, in order to protect the natural environment and reduce costs, research has been conducted to replace cellulose acetate tow with environmentally friendly materials. For example, unlike cellulose acetate, tow using lyocell fibers obtained by fiberizing cellulose itself is being developed.
在製備用於吸菸製品的過濾嘴時，通過添加可以特異性減少吸菸過程中產生的苯酚類的苯酚類減少物質來減少主流菸氣中的苯酚菸氣成分。以往，作為苯酚類減少物質，已知將聚乙二醇（polyethylene glycol；以下稱為“PEG”）、檸檬酸三乙酯（triethyl citrate；以下稱為“TEC”）及三醋精（triacetin；以下稱為“TA”）等添加到醋酸纖維素絲束。當將由PEG、TEC及TA組成的苯酚類減少物質添加到疏水性醋酸纖維素中時，苯酚類減少物質還對醋酸纖維素纖維發揮增塑劑功能，因此存在使疏水性醋酸纖維素纖維彼此結合，從而降低生物降解性的問題。When preparing filters for smoking products, phenolic smoke components in mainstream smoke are reduced by adding phenol-reducing substances that can specifically reduce phenols generated during smoking. Conventionally, polyethylene glycol (PEG), triethyl citrate (TEC), and triacetin (TA) are known to be added to cellulose acetate tow as phenol-reducing substances. When a phenol-reducing substance composed of PEG, TEC, and TA is added to hydrophobic cellulose acetate, the phenol-reducing substance also functions as a plasticizer for cellulose acetate fibers, thereby causing the hydrophobic cellulose acetate fibers to bind to each other, thereby reducing biodegradability.
另一方面，當將如PEG、TEC及TA等的苯酚類減少物質添加到萊賽爾纖維中時，萊賽爾纖維不會被增塑化。因此，發現當向萊賽爾纖維中添加PEG、TEC及TA等苯酚類減少物質時，生物降解性並不降低，並在主流菸氣中的苯酚菸霧成分減少。On the other hand, when phenol reducing substances such as PEG, TEC and TA are added to Lyocell fibers, the Lyocell fibers are not plasticized. Therefore, it is found that when phenol reducing substances such as PEG, TEC and TA are added to Lyocell fibers, the biodegradability is not reduced and the phenol smoke component in the mainstream smoke is reduced.
另一方面，當在萊賽爾纖維中添加PEG、TEC及TA等苯酚類減少物質來降低主流菸氣中的苯酚菸霧成分時，含有萊賽爾纖維的萊賽爾絲束不被增塑化，導致萊賽爾絲束的硬度降低，出現如過濾嘴崩潰等的問題。為了彌補上述硬度降低的問題，正在提出如下的解決方案：當製備用於吸菸製品的過濾嘴時，使用稱為硬卷紙的高基重卷紙來包裹圍繞萊賽爾絲束的過濾嘴部包裝紙，從而對用於吸菸製品的過濾嘴賦予預定的硬度。On the other hand, when phenol reducing substances such as PEG, TEC and TA are added to Lyocell fibers to reduce the phenol smoke component in mainstream tobacco, the Lyocell bundle containing the Lyocell fibers is not plasticized, resulting in a decrease in the hardness of the Lyocell bundle, causing problems such as filter collapse. In order to compensate for the above-mentioned problem of reduced hardness, the following solution is being proposed: when preparing a filter for a smoking product, a high basis weight wrapping paper called hard wrapping paper is used to wrap the filter wrapping paper surrounding the Lyocell bundle, thereby giving a predetermined hardness to the filter for the smoking product.
另一方面，硬卷紙具有比一般卷紙更高的基重，因此對用於吸菸製品的過濾嘴賦予預定的硬度，但是分散在萊賽爾絲束中的苯酚類減少物質從包含萊賽爾絲束的過濾嘴部轉移並吸收到過濾嘴卷紙（以下稱為過濾嘴部包裝紙），從而出現用於吸菸製品的過濾嘴的苯酚減少性能劣化的問題。On the other hand, hard rolling paper has a higher basis weight than general rolling paper, and thus imparts a predetermined hardness to the filter tip for smoking products, but the phenol-reducing substances dispersed in the lyocell bundle are transferred from the filter tip containing the lyocell bundle and absorbed into the filter tip rolling paper (hereinafter referred to as the filter tip wrapping paper), thereby causing a problem of deterioration in the phenol-reducing performance of the filter tip for smoking products.

圖1為示出根據本發明的一實施例的吸菸製品的示意性結構的圖。FIG. 1 is a diagram showing a schematic structure of a smoking product according to an embodiment of the present invention.
在整個說明書中，“吸菸製品”可以指能夠產生氣溶膠的製品，例如香菸（捲菸）、雪茄等。吸菸製品可包含氣溶膠生成物質或氣溶膠形成基質。另外，吸菸製品可包括基於菸草原料的固體材料，例如，再造菸草、斗菸絲、重組菸草等。吸菸物質可以包括揮發性化合物。Throughout the specification, "smoking products" may refer to products that can generate aerosols, such as cigarettes (rolling tobacco), cigars, etc. Smoking products may contain aerosol-forming substances or aerosol-forming substrates. In addition, smoking products may include solid materials based on tobacco raw materials, such as reconstituted tobacco, pipe tobacco, reconstituted tobacco, etc. Smoking substances may include volatile compounds.
此外，在整個說明書中，“上游”或“上游方向”可以是指從抽吸吸菸製品100的用戶的口部遠離的方向，而“下游”或“下游方向”可以是指靠近抽吸吸菸製品100的用戶的口部的方向。例如，在如圖1所示的吸菸製品100中，吸菸物質部10位於用於吸菸製品的過濾嘴中包含的過濾嘴部20的上游或在上游方向上的位置。Furthermore, throughout the specification, “upstream” or “upstream direction” may refer to a direction away from the mouth of a user who inhales the smoking product 100, and “downstream” or “downstream direction” may refer to a direction close to the mouth of a user who inhales the smoking product 100. For example, in the smoking product 100 shown in FIG1 , the smoking substance portion 10 is located upstream or in the upstream direction of the filter portion 20 included in the filter portion for the smoking product.
進而，雖然在本說明書中以吸菸製品100是燃燒式捲菸為例進行了描述，但本發明不限於此，吸菸製品100也可以是與如電子菸設備等的氣溶膠生成裝置（圖中未示出）一起使用的加熱式捲菸等。Furthermore, although the smoking product 100 is described in this specification as a combustion-type cigarette, the present invention is not limited thereto, and the smoking product 100 may also be a heated cigarette used in conjunction with an aerosol generating device (not shown) such as an electronic cigarette device.
參照圖1，吸菸製品100包括吸菸物質部10、過濾嘴部20、吸菸物質部包裝紙30a、過濾嘴部包裝紙30b及接裝紙40。用於吸菸製品的過濾嘴可包括過濾嘴部20和圍繞過濾嘴部20的過濾嘴部包裝紙30b。在吸菸製品100中，吸菸物質部10與過濾嘴部20相比位於上游側。1 , a smoking product 100 includes a smoking substance portion 10, a filter portion 20, a smoking substance portion wrapping paper 30a, a filter portion wrapping paper 30b, and a tipping paper 40. The filter for the smoking product may include a filter portion 20 and a filter portion wrapping paper 30b surrounding the filter portion 20. In the smoking product 100, the smoking substance portion 10 is located at an upstream side compared to the filter portion 20.
吸菸物質部10可以被如原料菸葉、再造菸葉或將菸葉和再造菸葉混合的混合物等的吸菸物質填充。經加工的吸菸物質可以以薄片狀或斗菸絲狀填充在吸菸物質部10中。上述吸菸物質部10可以具有延伸的長桿狀，對其長度、周長及直徑沒有特別限制，但是可以根據吸菸物質的填充量、用戶的喜好等來調節為本領域常用的尺寸。The smoking substance portion 10 may be filled with a smoking substance such as raw tobacco leaves, recycled tobacco leaves, or a mixture of tobacco leaves and recycled tobacco leaves. The processed smoking substance may be filled in the smoking substance portion 10 in the form of a sheet or a pipe tobacco shred. The smoking substance portion 10 may have an extended long rod shape, and its length, circumference, and diameter are not particularly limited, but may be adjusted to a size commonly used in the art according to the filling amount of the smoking substance, the user's preference, and the like.
吸菸物質部10可包括甘油、丙二醇、乙二醇、二丙二醇、二甘醇、三甘醇、四甘醇及油醇中的至少一種氣溶膠生成物質。上述吸菸物質部10可以包含如調味劑、潤濕劑和/或乙酸鹽化合物等的其他添加物質。上述氣溶膠生成物質和添加物質可以包含在吸菸物質中。The smoking substance portion 10 may include at least one aerosol-forming substance selected from the group consisting of glycerol, propylene glycol, ethylene glycol, dipropylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and oleyl alcohol. The smoking substance portion 10 may include other additives such as flavorings, wetting agents, and/or acetate compounds. The aerosol-forming substance and additives may be included in the smoking substance.
上述吸菸物質部10可以由吸菸物質部包裝紙30a包裹。在一般吸菸物質部10的燃燒過程中產生的香菸菸氣中一部分在穿過香菸過濾嘴之前通過吸菸物質部包裝紙30a釋放到大氣中，側流菸氣給二手吸菸者帶來不適。為了減少上述側流菸氣，有了各種嘗試，例如在現有捲菸紙中添加氧化鎂、氧化鈦、氧化鈰、氧化鋁、碳酸鈣、碳酸鋯等填料等，但在簡單地通過使用這些填料來減少側流菸氣時，發生吸菸感降低、或燃燒熄滅、菸灰完整性降低等問題，因此難以通過適當組合填料所用材料來解決上述問題。在一些實施例中，為了在減少側流菸氣的同時防止吸菸感、菸灰完整性的降低及燃燒熄滅，吸菸物質部包裝紙30a可以應用混合鎂氧化物（MgO和/或Mg(OH)2）及碳酸鈣（CaCO3）的填料。The smoking substance portion 10 may be wrapped by a smoking substance portion wrapping paper 30a. In general, part of the cigarette smoke generated during the combustion of the smoking substance portion 10 is released into the atmosphere through the smoking substance portion wrapping paper 30a before passing through the cigarette filter, and the sidestream smoke brings discomfort to second-hand smokers. In order to reduce the above-mentioned sidestream smoke, various attempts have been made, such as adding fillers such as magnesium oxide, titanium oxide, tantalum oxide, aluminum oxide, calcium carbonate, zirconium carbonate, etc. to existing tobacco paper. However, when simply using these fillers to reduce sidestream smoke, problems such as reduced smoking sensation, burnout, and reduced ash integrity occur. Therefore, it is difficult to solve the above problems by appropriately combining the materials used for the fillers. In some embodiments, in order to reduce the sidestream smoke while preventing the reduction of smoking sensation, ash integrity, and burnout, the smoking material portion packaging paper 30a can use a filler of mixed magnesium oxide (MgO and/or Mg(OH)2 ) and calcium carbonate (CaCO3 ).
用於吸菸製品的過濾嘴可布置在吸菸物質部10的下游。用於吸菸製品的過濾嘴的過濾嘴部20布置在吸菸物質部10的下游，以起到在用戶抽吸吸菸物質部10中產生的氣溶膠物質之前就經過的過濾嘴的作用。上述過濾嘴部20可以由各種材料或形狀製造。根據本發明的一實施例的過濾嘴部20可基本上包括在多根萊賽爾纖維中分散有苯酚類減少物質的萊賽爾絲束。包括上述萊賽爾絲束的用於吸菸製品的過濾嘴可以替換現有吸菸製品的過濾嘴部20的全部或一部分，當替換一部分時，可以一起使用以往使用的過濾材料。現有的過濾材料可包括例如醋酸纖維素過濾過濾嘴、空心管過濾嘴等。The filter for smoking products may be arranged downstream of the smoking substance section 10. The filter portion 20 of the filter for smoking products is arranged downstream of the smoking substance section 10 to play the role of a filter that the user passes through before the aerosol substance generated in the smoking substance section 10 is inhaled. The filter portion 20 may be made of various materials or shapes. The filter portion 20 according to an embodiment of the present invention may basically include a lyocell bundle in which a phenol-reducing substance is dispersed in a plurality of lyocell fibers. The filter for smoking products including the above-mentioned Lyocell bundle can replace all or part of the filter portion 20 of the existing smoking products. When replacing a part, the previously used filter material can be used together. The existing filter material may include, for example, a cellulose acetate filter, a hollow tube filter, etc.
儘管圖1中過濾嘴部20被圖示為由單一過濾嘴構成的單過濾嘴，但本發明不限於此。例如，上述過濾嘴部20當然可以被設置為具備兩個以上的過濾嘴的雙重過濾嘴或三重過濾嘴等，以提高過濾效率。Although the filter unit 20 is illustrated as a single filter consisting of a single filter in Fig. 1, the present invention is not limited thereto. For example, the filter unit 20 may be configured as a double filter or a triple filter having two or more filter nozzles to improve filtering efficiency.
在一些實施例中，當上述過濾嘴部20設置為雙重過濾嘴或三重過濾嘴等時，多個過濾嘴中的任一個可以為本發明的包括包含萊賽爾纖維的萊賽爾絲束和分散在萊賽爾絲束的苯酚類減少物質的過濾嘴（以下稱為萊賽爾過濾嘴），而多個過濾嘴中的另一個可以為醋酸纖維素過濾嘴和/或紙過濾嘴。在這種情況下，本發明的萊賽爾過濾嘴的長度可以是過濾嘴部20的總長度的25%至50%。此外，雖然圖中未示出，在過濾嘴部20的內部還可包含可壓碎的膠囊（圖中未示出），上述膠囊具有用薄膜包圍包含香料的內容物溶液的結構。In some embodiments, when the filter unit 20 is configured as a double filter or a triple filter, any one of the plurality of filters may be a filter comprising a lyocell bundle containing lyocell fibers and a phenol-reducing substance dispersed in the lyocell bundle (hereinafter referred to as a lyocell filter) of the present invention, and another one of the plurality of filters may be a cellulose acetate filter and/or a paper filter. In this case, the length of the lyocell filter of the present invention may be 25% to 50% of the total length of the filter unit 20. In addition, although not shown in the figure, the filter mouthpiece 20 may further include a crushable capsule (not shown in the figure) inside, wherein the capsule has a structure in which a content solution containing a fragrance is surrounded by a film.
過濾嘴部包裝紙30b包圍過濾嘴部20，且能夠包裝過濾嘴部20。過濾嘴部包裝紙30b可以由具有耐油性的硬卷紙製成。稍後將說明過濾嘴部包裝紙30b的詳細內容。儘管本發明不限於此，但過濾嘴部包裝紙30b的面向過濾嘴部20的內表面還可以包括鋁箔。The filter nozzle wrapping paper 30b surrounds the filter nozzle 20 and can wrap the filter nozzle 20. The filter nozzle wrapping paper 30b can be made of a hard roll paper having oil resistance. The details of the filter nozzle wrapping paper 30b will be described later. Although the present invention is not limited thereto, the inner surface of the filter nozzle wrapping paper 30b facing the filter nozzle 20 may also include aluminum foil.
由上述吸菸物質部包裝紙30a包裹的吸菸物質部10和由過濾嘴部包裝紙30b包裹的過濾嘴部20可以由接裝紙40結合包裝。如圖1所示，上述接裝紙40可以圍繞吸菸物質部包裝紙30a的至少一部分（例如，下游的一部分區域）和過濾嘴部包裝紙30b的外圍。換句話說，吸菸物質部10的至少一部分和過濾嘴部20可以被接裝紙40進一步包裝，以物理結合。The smoking substance portion 10 wrapped by the smoking substance portion wrapping paper 30a and the filter mouth portion 20 wrapped by the filter mouth portion wrapping paper 30b may be combined and packaged by the tipping paper 40. As shown in FIG1 , the tipping paper 40 may surround at least a portion (e.g., a portion of the downstream area) of the smoking substance portion wrapping paper 30a and the outer periphery of the filter mouth portion wrapping paper 30b. In other words, at least a portion of the smoking substance portion 10 and the filter mouth portion 20 may be further wrapped by the tipping paper 40 to be physically combined.
根據本發明的一實施例，上述接裝紙40可由不經過耐油處理的無孔卷紙製成，但本發明不限於此。並且，上述接裝紙40也可以通過包括不燃性物質來防止過濾嘴部20燃燒的現象，但本發明不限於此。According to an embodiment of the present invention, the tipping paper 40 may be made of a non-porous roll paper that has not been subjected to oil-resistant treatment, but the present invention is not limited thereto. Furthermore, the tipping paper 40 may also include a non-combustible substance to prevent the filter nozzle 20 from burning, but the present invention is not limited thereto.
另外，雖然在附圖中未示出，但是吸菸製品100還可以包括中空管結構，上述中空管結構是在內部包含中空的管狀結構。上述中空管結構可布置在萊賽爾過濾嘴的下游。In addition, although not shown in the drawings, the smoking product 100 may further include a hollow tube structure, which is a tubular structure having a hollow interior. The hollow tube structure may be arranged downstream of the Lyocell filter.
在一些實施例中，可以在上述中空管結構中形成有穿孔，但不限於此。上述中空管結構中可以不形成穿孔。在一些實施例中，當穿孔形成在上述中空管結構中時，上述穿孔可形成在距吸菸製品100的下游末端在上游方向上10mm至15mm的距離處。In some embodiments, a perforation may be formed in the hollow tube structure, but is not limited thereto. The hollow tube structure may not have a perforation. In some embodiments, when a perforation is formed in the hollow tube structure, the perforation may be formed at a distance of 10 mm to 15 mm in the upstream direction from the downstream end of the smoking product 100.
在下文中，將詳細描述根據本發明的一實施例的用於吸菸製品的過濾嘴。Hereinafter, a filter mouthpiece for smoking products according to an embodiment of the present invention will be described in detail.
本發明涉及一種包括在吸菸製品100中的用於吸菸製品的過濾嘴，根據本發明的一實施例的用於吸菸製品的過濾嘴包括：過濾嘴部20，包含萊賽爾絲束和苯酚類減少物質，上述萊賽爾絲束含有萊賽爾纖維，上述苯酚類減少物質分散在上述萊賽爾絲束中；及過濾嘴部包裝紙30b，圍繞上述過濾嘴部20。The present invention relates to a filter for smoking products included in a smoking product 100. According to an embodiment of the present invention, the filter for smoking products includes: a filter portion 20, comprising a lyocell bundle and a phenol-reducing substance, wherein the lyocell bundle contains lyocell fibers, and the phenol-reducing substance is dispersed in the lyocell bundle; and a filter portion wrapping paper 30b surrounding the filter portion 20.
上述萊賽爾纖維是利用從木漿提取的纖維素製成的環保纖維。上述萊賽爾絲束是指相鄰的萊賽爾纖維之間交叉連接而形成的束。The lyocell fiber is an environmentally friendly fiber made from cellulose extracted from wood pulp. The lyocell bundle is a bundle formed by cross-linking adjacent lyocell fibers.
在一些實施例中，萊賽爾纖維可具有異形截面。異形截面被定義為其截面不是圓形而是包括多個突起的形狀。例如，多個突起從中心延伸的形狀的截面可以被稱為異形截面。In some embodiments, the lyocell fiber may have a profiled cross section. A profiled cross section is defined as a cross section that is not circular but includes a plurality of protrusions. For example, a cross section in which a plurality of protrusions extend from the center may be referred to as a profiled cross section.
在一些實施例中，萊賽爾纖維可具有包括從中心分支的三個突起的Y形截面、包括四個突起的十字形截面、包括五個或更多個突起的星形截面，或O形截面，但本發明不限於此。In some embodiments, the lyocell fiber may have a Y-shaped cross-section including three protrusions branching from the center, a cross-shaped cross-section including four protrusions, a star-shaped cross-section including five or more protrusions, or an O-shaped cross-section, but the present invention is not limited thereto.
在一實施例中，上述苯酚類減少物質對應於能夠特異性減少在吸菸時產生的苯酚類的物質，其可以包括聚乙二醇（以下稱為“PEG”）、檸檬酸三乙酯（以下稱為“TEC”）及三醋精（以下稱為“TA”）中的至少一種。In one embodiment, the phenol-reducing substance corresponds to a substance capable of specifically reducing phenols produced during smoking, which may include at least one of polyethylene glycol (hereinafter referred to as "PEG"), triethyl citrate (hereinafter referred to as "TEC") and triacetin (hereinafter referred to as "TA").
在一些實施例中，苯酚類減少物質可以包括PEG，或可以包括TEC，或可以包括PEG和TEC兩者。然而，本發明不限於此，作為進一步添加到上述PEG、TEC及TA中的至少一種的苯酚類功能性物質，只要是能夠減少吸菸時產生的苯酚類的物質，就不受限制。In some embodiments, the phenol reducing substance may include PEG, or may include TEC, or may include both PEG and TEC. However, the present invention is not limited thereto, and the phenol functional substance further added to at least one of the above-mentioned PEG, TEC and TA is not limited as long as it is a substance that can reduce phenols generated during smoking.
在一些實施例中，苯酚類減少物質可以均勻地分散在萊賽爾絲束中，且分布在構成過濾嘴部20的萊賽爾絲束的整個區域中。In some embodiments, the phenol-reducing substance can be uniformly dispersed in the lyocell bundle and distributed throughout the entire area of the lyocell bundle constituting the filter mouth portion 20.
上述苯酚類減少物質可以塗布到構成萊賽爾絲束的萊賽爾纖維的表面上。另一方面，作為根據一實施例的苯酚類減少物質的示例性物質的PEG、TEC及TA中的至少一種對於醋酸纖維素纖維起到增塑劑的功能，但對於萊賽爾纖維可能不起到增塑劑的作用。因此，當包含PEG、TEC及TA中的至少一種作為苯酚類減少物質時，即使將上述苯酚類減少物質塗布於萊賽爾纖維的表面上，萊賽爾纖維也不會被上述苯酚類減少物質增塑化。The above-mentioned phenolic reducing substances can be applied on the surface of the lyocell fiber constituting the lyocell bundle. On the other hand, at least one of PEG, TEC and TA as exemplary substances of the phenolic reducing substances according to an embodiment functions as a plasticizer for cellulose acetate fiber, but may not function as a plasticizer for lyocell fiber. Therefore, when at least one of PEG, TEC and TA is included as the phenolic reducing substances, even if the above-mentioned phenolic reducing substances are applied on the surface of the lyocell fiber, the lyocell fiber will not be plasticized by the above-mentioned phenolic reducing substances.
應用了根據本發明的萊賽爾絲束的用於吸菸製品的過濾嘴包括分散在萊賽爾絲束上的PEG、TEC或TA中的至少一種苯酚類減少物質，因此與沒有添加苯酚類減少物質的用於吸菸製品的過濾嘴相比，在吸菸時發生的苯酚類減少效果可以優異。The filter for smoking products to which the lyocell bundle according to the present invention is applied includes at least one phenol reducing substance among PEG, TEC or TA dispersed on the lyocell bundle, so that the phenol reducing effect occurring during smoking can be excellent compared to the filter for smoking products to which the phenol reducing substance is not added.
在一些實施例中，在苯酚類減少物質中包含的聚乙二醇（PEG）的重均分子量（M.W；weight average molecular weight）可以為50至10,000、50至2500、200至2000、500至700或600。In some embodiments, the weight average molecular weight (M.W) of polyethylene glycol (PEG) contained in the phenol-reducing substance may be 50 to 10,000, 50 to 2500, 200 to 2000, 500 to 700 or 600.
在一些實施例中，當苯酚類減少物質包括TEC和PEG時，TEC與PEG的含量比率可以為9:1至7:3，但本發明不限於此。In some embodiments, when the phenol-reducing substance includes TEC and PEG, the content ratio of TEC to PEG can be 9:1 to 7:3, but the present invention is not limited thereto.
當分散在萊賽爾絲束中的苯酚類減少物質包含聚乙二醇（PEG）時，用於吸菸製品的過濾嘴的苯酚類減少性能可能根據上述聚乙二醇（PEG）的分子量而不同。具體地，當分散在萊賽爾絲束中的聚乙二醇（PEG）具有在上述範圍內的重均分子量時，使用上述萊賽爾絲束製備的用於吸菸製品的過濾嘴的苯酚類減少性能可以優異。較佳地，當分散在萊賽爾絲束中的聚乙二醇（PEG）的重均分子量為600時，使用上述萊賽爾絲束製備的用於吸菸製品的過濾嘴的苯酚類減少性能可能是最優異的，但是上述聚乙二醇（PEG）的分子量不限於此。When the phenol-reducing substance dispersed in the lyocell tow includes polyethylene glycol (PEG), the phenol-reducing performance of the filter for a smoking product may differ according to the molecular weight of the polyethylene glycol (PEG). Specifically, when the polyethylene glycol (PEG) dispersed in the lyocell tow has a weight average molecular weight within the above range, the phenol-reducing performance of the filter for a smoking product prepared using the lyocell tow may be excellent. Preferably, when the weight average molecular weight of the polyethylene glycol (PEG) dispersed in the lyocell bundle is 600, the phenol reduction performance of the filter for smoking products prepared using the lyocell bundle may be the best, but the molecular weight of the polyethylene glycol (PEG) is not limited thereto.
過濾嘴部包裝紙30b可布置成圍繞過濾嘴部20。過濾嘴部包裝紙30b具有預定值以上的基重，並且可以由經過耐油處理的耐油性硬卷紙構成（製成）。The filter nozzle wrapping paper 30b may be arranged to surround the filter nozzle 20. The filter nozzle wrapping paper 30b has a basis weight of a predetermined value or more and may be composed (made) of an oil-resistant hard paper that has been subjected to an oil-resistant treatment.
另一方面，過濾嘴部包裝紙30b由具有預定數值以上的基重的硬卷紙構成，使得其不僅可以起到圍繞包含萊賽爾絲束的過濾嘴部20的包裝材料的作用，而且可以起到對根據本發明的用於吸菸製品的過濾嘴賦予一定水平以上的硬度的作用。On the other hand, the filter mouth wrapping paper 30b is made of a hard tissue paper having a basis weight greater than a predetermined value, so that it can not only serve as a wrapping material surrounding the filter mouth portion 20 containing the lyocell bundle, but also serve to impart a certain level of hardness to the filter mouth for the smoking product according to the present invention.
具體地，當過濾嘴部20由分散有PEG、TEC及TA中的至少一種苯酚類減少物質的萊賽爾絲束構成時，萊賽爾纖維不會被苯酚類減少物質增塑化，導致上述萊賽爾絲束的硬度降低。因此，包圍過濾嘴部20的過濾嘴部包裝紙30b由具有預定值以上的基重的硬卷紙構成，以能夠補充用於吸菸製品的過濾嘴的硬度。Specifically, when the filter 20 is composed of a lyocell bundle in which at least one phenol-reducing substance among PEG, TEC and TA is dispersed, the lyocell fiber is not plasticized by the phenol-reducing substance, resulting in a decrease in the hardness of the lyocell bundle. Therefore, the filter wrapping paper 30b surrounding the filter 20 is composed of a hard paper having a basis weight greater than a predetermined value, so as to be able to supplement the hardness of the filter used for the smoking product.
在一些實施例中，過濾嘴部包裝紙30b可以包括基重為30gsm至180gsm、35gsm至170gsm、40gsm至160gsm、50gsm至158gsm、60gsm至155gsm、70gsm至150gsm或75gsm至150gsm的卷紙。由於過濾嘴部包裝紙30b由具有高基重的卷紙構成，因此包括分散有苯酚類減少物質的萊賽爾絲束的過濾嘴部20的硬度由過濾嘴部包裝紙30b補充，使得用於吸菸製品的過濾嘴的硬度達到預定水平以上，從而可以解決用於吸菸製品的過濾嘴的硬度降低問題。In some embodiments, the filter mouth wrapper 30b may include a roll of paper having a basis weight of 30gsm to 180gsm, 35gsm to 170gsm, 40gsm to 160gsm, 50gsm to 158gsm, 60gsm to 155gsm, 70gsm to 150gsm, or 75gsm to 150gsm. Since the filter mouth wrapper 30b is composed of a roll of paper having a high basis weight, the hardness of the filter mouth 20 including the lyocell bundle in which the phenol-based reducing substance is dispersed is supplemented by the filter mouth wrapper 30b, so that the hardness of the filter mouth for smoking products reaches a predetermined level or more, thereby solving the problem of reduced hardness of the filter mouth for smoking products.
在一些實施例中，過濾嘴部包裝紙30b可以由經過耐油處理的耐油性卷紙製成。對過濾嘴部包裝紙30b賦予耐油性的耐油處理可以通過對具有預定數值以上的基重的卷紙用耐油塗覆物質以施膠壓榨（Size-Press）方式進行。在示例性實施例中，耐油塗覆物質可包括氟代丙烯酸酯共聚物（Fluoracrylate Copolymer），但本發明不限於此，作為耐油塗覆物質，只要是能夠對硬卷紙賦予耐油性的物質，就不受限制。In some embodiments, the filter nozzle wrapping paper 30b may be made of oil-resistant roll paper that has been subjected to oil-resistant treatment. The oil-resistant treatment for imparting oil resistance to the filter nozzle wrapping paper 30b may be performed by applying an oil-resistant coating material to roll paper having a basis weight greater than a predetermined value by size-pressing. In an exemplary embodiment, the oil-resistant coating material may include a fluoroacrylate copolymer, but the present invention is not limited thereto, and the oil-resistant coating material is not limited as long as it is a material that can impart oil resistance to the hard roll paper.
過濾嘴部包裝紙30b可包括朝向過濾嘴部20的第一表面（或內表面）和與第一表面（內表面）相對的第二表面（或外表面），過濾嘴部包裝紙30b的內表面和外表面中至少一個表面可以經過耐油處理。The filter nozzle wrapper 30b may include a first surface (or inner surface) facing the filter nozzle 20 and a second surface (or outer surface) opposite to the first surface (inner surface), and at least one of the inner surface and the outer surface of the filter nozzle wrapper 30b may be subjected to oil resistance treatment.
在示例性實施例中，僅過濾嘴部包裝紙30b的內表面可經過耐油處理，使得僅過濾嘴部包裝紙30b的內表面可具有耐油性，或者僅過濾嘴部包裝紙30b的外表面可經過耐油處理，使得僅過濾嘴部包裝紙30b的外表面可具有耐油性，或者過濾嘴部包裝紙30b的內表面和外表面都可經過耐油處理，使得內表面和外表面都可具有耐油性。In an exemplary embodiment, only the inner surface of the filter nozzle wrapping paper 30b may be treated with oil resistance so that only the inner surface of the filter nozzle wrapping paper 30b has oil resistance, or only the outer surface of the filter nozzle wrapping paper 30b may be treated with oil resistance so that only the outer surface of the filter nozzle wrapping paper 30b has oil resistance, or both the inner and outer surfaces of the filter nozzle wrapping paper 30b may be treated with oil resistance so that both the inner and outer surfaces have oil resistance.
由於過濾嘴部包裝紙30b由經過耐油處理的卷紙製成，因此與未經耐油處理的（即，不具有耐油性的）卷紙相比，可以使從分散有苯酚類減少物質的萊賽爾絲束轉移到過濾嘴部包裝紙30b的苯酚類減少物質的轉移率最小化。具體地，由於過濾嘴部包裝紙30b經過耐油處理，因此過濾嘴部包裝紙30b具有耐油性，從而可以防止在分散於萊賽爾絲束中的苯酚類減少物質中從萊賽爾絲束移動到過濾嘴部包裝紙30b的苯酚類減少物質轉移到過濾嘴部包裝紙30b。因此，可以防止萊賽爾絲束上的苯酚類減少物質被吸收到過濾嘴部包裝紙30b中。因此，可以解決過濾嘴部包裝紙30b被苯酚類減少物質潤濕，導致用於吸菸製品的過濾嘴的硬度降低的問題、或者殘留在萊賽爾絲束上的苯酚類減少物質的殘留量減少的問題。Since the filter nozzle wrapping paper 30b is made of a roll paper that has been subjected to an oil-resistant treatment, the transfer rate of the phenol-based reducing substances from the lyocell bundle in which the phenol-based reducing substances are dispersed to the filter nozzle wrapping paper 30b can be minimized compared to a roll paper that has not been subjected to an oil-resistant treatment (i.e., has no oil resistance). Specifically, since the filter nozzle wrapping paper 30b has been subjected to an oil-resistant treatment, the filter nozzle wrapping paper 30b has oil resistance, thereby preventing the phenol-based reducing substances that have moved from the lyocell bundle to the filter nozzle wrapping paper 30b from being dispersed in the lyocell bundle from being transferred to the filter nozzle wrapping paper 30b. Therefore, the phenolic reducing substances on the lyocell bundle can be prevented from being absorbed into the filter tip wrapper 30b. Therefore, the problem that the filter tip wrapper 30b is moistened by the phenolic reducing substances, resulting in a decrease in the hardness of the filter tip for smoking products, or the problem that the amount of the phenolic reducing substances remaining on the lyocell bundle is reduced can be solved.
在一些實施例中，基於3M KIT方法，過濾嘴部包裝紙30b具有8以上、9以上、10以上、11以上的耐油度。過濾嘴部包裝紙30b的上述耐油度可以是通過測定過濾嘴部包裝紙30b的外表面和內表面中的至少一個表面的耐油度而獲得的值。在一些實施例中，在過濾嘴部包裝紙30b的外表面和內表面上均進行耐油處理，並且過濾嘴部包裝紙30b的外表面和內表面的耐油度分別可以為8以上、9以上、10以上、11以上。由於過濾嘴部包裝紙30b由具有上述耐油度的耐油性硬卷紙構成，因此可以減少從萊賽爾絲束轉移到過濾嘴部包裝紙30b的苯酚類減少物質的轉移量。In some embodiments, the filter nozzle wrapper 30b has an oil resistance of 8 or more, 9 or more, 10 or more, or 11 or more based on the 3M KIT method. The above oil resistance of the filter nozzle wrapper 30b may be a value obtained by measuring the oil resistance of at least one of the outer surface and the inner surface of the filter nozzle wrapper 30b. In some embodiments, the outer surface and the inner surface of the filter nozzle wrapper 30b are both subjected to oil resistance treatment, and the oil resistance of the outer surface and the inner surface of the filter nozzle wrapper 30b may be 8 or more, 9 or more, 10 or more, or 11 or more, respectively. Since the filter nozzle wrapping paper 30b is made of the oil-resistant hard paper having the above-mentioned oil resistance, the amount of phenol-reducing substances transferred from the lyocell tow to the filter nozzle wrapping paper 30b can be reduced.
另一方面，使用3M KIT方法的耐油度測定如下進行。具體地，為了分析卷紙的耐油度，通過採用常用的方法製備耐油度測定溶液，將其滴在試片上，經過一定時間後，根據在試片上沒有留下油迹的最高溶液編號來判斷耐油度。溶液製備方法如下：通過將蓖麻油、甲苯及庚烷以按如下述表1中所示的試劑盒編號確定的比例混合來製備溶液。On the other hand, the oil resistance measurement using the 3M KIT method is performed as follows. Specifically, in order to analyze the oil resistance of the roll paper, an oil resistance measurement solution is prepared by a common method, dripped on a test piece, and the oil resistance is judged based on the highest solution number that leaves no oil marks on the test piece after a certain period of time. The solution preparation method is as follows: The solution is prepared by mixing castor oil, toluene and heptane in a ratio determined by the kit number as shown in Table 1 below.
[表1]
對於試片使用從最低試劑盒編號的試劑開始進行測試，將所製備的一滴試劑滴加到試片上，經過15秒後，用濕棉墊或紙巾吸去滴下的試劑，然後檢查是否有油痕。若沒有油痕，則提高試劑盒編號繼續進行測試，直到出現油痕。通過應用無油痕的最終試劑盒編號來評價耐油性。基於上述3M KIT方法評價根據本申請的氣溶膠產生物品的耐油性的結果證實了根據實施例的過濾嘴部包裝紙30b的基於3M KIT方法的耐油度可以為8以上、9以上、10以上或11以上。For the test piece, the test is started with the reagent with the lowest reagent box number, and a drop of the prepared reagent is added to the test piece. After 15 seconds, the dripped reagent is absorbed with a wet cotton pad or a paper towel, and then it is checked whether there is an oil mark. If there is no oil mark, the reagent box number is increased and the test is continued until an oil mark appears. The oil resistance is evaluated by applying the final reagent box number without an oil mark. The results of evaluating the oil resistance of the aerosol product according to the present application based on the above-mentioned 3M KIT method confirm that the oil resistance of the filter nozzle packaging paper 30b according to the embodiment based on the 3M KIT method can be 8 or more, 9 or more, 10 or more, or 11 or more.
在一些實施例中，根據本發明的包括過濾嘴部20和圍繞過濾嘴部的過濾嘴部包裝紙30b的用於吸菸製品的過濾嘴可以具有93%至99%、93.5%至98.5%、94%至98%、94.3%至97.8%或93.4%至97%的硬度。上述用於吸菸製品的過濾嘴的硬度是將當在垂直於用於吸菸製品的過濾嘴的縱向方向的方向上以一定水平的力量按壓用於吸菸製品的過濾嘴時保持用於吸菸製品的過濾嘴的直徑的程度數值化的值，其可以是在施加力量之後的用於吸菸製品的過濾嘴的直徑與在施加力量之前的用於吸菸製品的過濾嘴的直徑之間的比率的百分比值。In some embodiments, the filter for smoking products according to the present invention, including the filter 20 and the filter wrapper 30b surrounding the filter, may have a hardness of 93% to 99%, 93.5% to 98.5%, 94% to 98%, 94.3% to 97.8% or 93.4% to 97%. The hardness of the filter tip for smoking products described above is a value that quantifies the degree to which the diameter of the filter tip for smoking products is maintained when the filter tip for smoking products is pressed with a certain level of force in a direction perpendicular to the longitudinal direction of the filter tip for smoking products, and it may be a percentage value of the ratio between the diameter of the filter tip for smoking products after the force is applied and the diameter of the filter tip for smoking products before the force is applied.
具體地，在根據本發明的用於吸菸製品的過濾嘴中，圍繞過濾嘴部20的過濾嘴部包裝紙30b由具有預定數值以上的基重且具有耐油性的耐油性硬卷紙構成，從而在彌補萊賽爾絲束的硬度的同時，還防止分散在萊賽爾絲束中的苯酚類減少物質轉移至過濾嘴部包裝紙30b並防止過濾嘴部包裝紙30b由於苯酚類減少物質潤濕，從而用於吸菸製品的過濾嘴可以具有在上述範圍內的硬度。Specifically, in the filter for smoking products according to the present invention, the filter tip wrapping paper 30b surrounding the filter tip 20 is composed of an oil-resistant hard tissue paper having a basis weight greater than a predetermined value and having oil resistance, thereby compensating for the hardness of the lyocell bundle while preventing the phenol-reducing substances dispersed in the lyocell bundle from transferring to the filter tip wrapping paper 30b and preventing the filter tip wrapping paper 30b from being wetted by the phenol-reducing substances, so that the filter for smoking products can have a hardness within the above-mentioned range.
在一實施例中，定義為相對於上述用於吸菸製品的過濾嘴中包含的上述苯酚類減少物質的總重量的上述過濾嘴部包裝紙30b中包含的上述苯酚類減少物質的重量的百分比值的上述苯酚類減少物質向過濾嘴部包裝紙30b的轉移率可以為1%至13%、1.2%至10%、1.4%至8%、1.6%至7%、1.8%至6%、2%至5%或3%至4.5%。另一方面，在上述用於吸菸製品的過濾嘴中包含的上述苯酚類減少物質的總重量可被計算為上述過濾嘴部20中包含的上述苯酚類減少物質的重量與上述過濾嘴部包裝紙30b中包含的上述苯酚類減少物質的重量之和。In one embodiment, the transfer rate of the phenol-reducing substances to the filter tip wrapper 30b, which is defined as a percentage value of the weight of the phenol-reducing substances contained in the filter tip wrapper 30b relative to the total weight of the phenol-reducing substances contained in the filter tip for smoking products, may be 1% to 13%, 1.2% to 10%, 1.4% to 8%, 1.6% to 7%, 1.8% to 6%, 2% to 5%, or 3% to 4.5%. On the other hand, the total weight of the phenol-reducing substances contained in the filter tip for smoking products may be calculated as the sum of the weight of the phenol-reducing substances contained in the filter tip 20 and the weight of the phenol-reducing substances contained in the filter tip wrapper 30b.
在下文中，將通過實施例和比較例更詳細地說明本發明的構造及其效果。然而，本實施例僅用於更具體地解釋本發明，而本發明的範圍不受這些實施例的限制。Hereinafter, the structure and effect of the present invention will be described in more detail by way of embodiments and comparative examples. However, the embodiments are only used to explain the present invention more specifically, and the scope of the present invention is not limited by these embodiments.

實驗例1：苯酚類減少物質向過濾嘴部包裝紙的轉移量的評價Experimental Example 1: Evaluation of the amount of phenol-reducing substances transferred to the filter nozzle wrapping paper
為了測定上述實施例1至2及比較例1至2的苯酚類減少物質向過濾嘴部包裝紙的轉移率（即，苯酚類減少物質向過濾嘴部包裝紙的轉移特性）而對用於吸菸製品的過濾嘴進行隨機取樣以測定用於吸菸製品的過濾嘴樣品的重量，並且，為了測定過濾嘴部包裝紙（即，過濾嘴卷紙）的重量而從取樣的用於吸菸製品的過濾嘴中除去萊賽爾絲束部分，以測定過濾嘴部包裝紙（即，過濾嘴卷紙）的重量。接著，對於每個取樣的過濾嘴樣品添加50mL的內標溶液中所含的提取溶液液並攪拌60分鐘，使用GC-FID（DB-WAX柱）分析TEC成分，並使用HPLD裝置分析PEG成分，以測定苯酚類減少物質的殘留量。In order to determine the transfer rate of the phenol-reducing substances to the filter tip wrapping paper (i.e., the transfer characteristics of the phenol-reducing substances to the filter tip wrapping paper) of the above-mentioned Examples 1 to 2 and Comparative Examples 1 to 2, the filter tip for smoking products was randomly sampled to determine the weight of the filter tip samples for smoking products, and, in order to determine the weight of the filter tip wrapping paper (i.e., filter tip wrapping paper), the lyocell tow portion was removed from the sampled filter tip for smoking products to determine the weight of the filter tip wrapping paper (i.e., filter tip wrapping paper). Next, 50 mL of the extraction solution contained in the internal standard solution was added to each sampled filter tip and stirred for 60 minutes. The TEC component was analyzed using GC-FID (DB-WAX column) and the PEG component was analyzed using HPLD to determine the residual amount of phenol-reducing substances.
接下來，計算在過濾嘴部包裝紙中包含的苯酚類減少物質的重量相對於在用於吸菸製品的過濾嘴中包含的苯酚類減少物質的總重量的百分比，並將其四捨五入至小數點後兩位，以此計算向過濾嘴部包裝紙的轉移率，將苯酚類減少物質的殘留量和向過濾嘴部包裝紙的轉移率的測定結果示於如下述表2和表3中。Next, the percentage of the weight of phenol-reducing substances contained in the filter mouthpiece wrapping paper relative to the total weight of phenol-reducing substances contained in the filter mouthpiece for smoking products was calculated and rounded to two decimal places to calculate the transfer rate to the filter mouthpiece wrapping paper. The measurement results of the residual amount of phenol-reducing substances and the transfer rate to the filter mouthpiece wrapping paper are shown in the following Tables 2 and 3.
[表2]
[表3]
如上述表2和表3所示，可以確認即使用具有相同基重的硬卷紙製備過濾嘴部包裝紙30b，也由於過濾嘴部包裝紙30b具有耐油性而苯酚類減少物質從過濾嘴部20向過濾嘴部包裝紙30b的轉移量（即，遷移量）減少。具體地，可以確認在包含作為相同的苯酚類減少物質的TEC的實施例1的情況下，與比較例1相比，由於過濾嘴部包裝紙30b具有耐油性而TEC從過濾嘴部20向過濾嘴部包裝紙30b的轉移率從26.5%顯著減少至4.3%，而在包含作為相同的苯酚類減少物質的PEG 600的實施例2的情況下，與比較例2相比，由於過濾嘴部包裝紙30b具有耐油性而PEG 600從過濾嘴部20向過濾嘴部包裝紙30b的轉移率從14.3%顯著減少至3.8%。因此，與一般硬卷紙相比，在耐油性硬卷紙的由萊賽爾絲束構成的過濾嘴部20中所含的苯酚類減少物質的殘留量增加，因此可以預測用於吸菸製品的過濾嘴的苯酚減少性能能夠得到改善。As shown in Tables 2 and 3 above, it can be confirmed that even when the filter nozzle wrapping paper 30b is prepared using a hard roll paper having the same basis weight, the amount of phenol-reducing substances transferred (i.e., the migration amount) from the filter nozzle 20 to the filter nozzle wrapping paper 30b is reduced because the filter nozzle wrapping paper 30b has oil resistance. Specifically, it was confirmed that in the case of Example 1 including TEC as the same phenol-reducing substance, the transfer rate of TEC from the filter nozzle 20 to the filter nozzle wrapping paper 30b was significantly reduced from 26.5% to 4.3% as compared with Comparative Example 1 due to the oil resistance of the filter nozzle wrapping paper 30b, and in the case of Example 2 including PEG 600 as the same phenol-reducing substance, the transfer rate of PEG 600 from the filter nozzle 20 to the filter nozzle wrapping paper 30b was significantly reduced from 14.3% to 3.8% as compared with Comparative Example 2 due to the oil resistance of the filter nozzle wrapping paper 30b. Therefore, the amount of phenol-reducing substances remaining in the filter portion 20 made of lyocell bundle of the oil-resistant hard wrapping paper increases compared to general hard wrapping paper, so it can be expected that the phenol reduction performance of the filter used for smoking products can be improved.

除了將包含TEC的苯酚類減少物質不是以50mg/rod而是以70mg/rod噴射到萊賽爾絲束上並添加之外，其餘以與實施例1相同的方法製備用於吸菸製品的過濾嘴。A filter for a smoking product was prepared in the same manner as in Example 1, except that the phenol-reducing substance containing TEC was sprayed onto the lyocell tow at 70 mg/rod instead of 50 mg/rod and added.

除了沒有將苯酚類減少物質噴射到萊賽爾絲束上（即，在過濾嘴部20中沒有添加苯酚類減少物質）之外，其餘以與比較例1相同的方法製備用於吸菸製品的過濾嘴。A filter for a smoking product was prepared in the same manner as in Comparative Example 1, except that the phenol-reducing substance was not sprayed onto the lyocell bundle (i.e., no phenol-reducing substance was added to the filter portion 20).
實驗例2：根據苯酚類減少物質的添加和過濾嘴部包裝紙的耐油處理的用於吸菸製品的過濾嘴的苯酚減少性能評價Experimental Example 2: Evaluation of the phenol reduction performance of a filter for smoking products based on the addition of phenol-reducing substances and the oil-resistant treatment of the filter wrapping paper
使用上述比較例1至2及實施例1、3的用於吸菸製品的過濾嘴來製備吸菸製品，通過劍橋濾墊（Cambridge filter pad；CFP）收集使用香菸吸菸機（cigarette smoking machine）HAUNI LX20 manual（直綫型（Linear type））作為吸菸裝置進行吸菸的菸霧成分，為了提取所收集的墊中的物質而添加30mL的1%乙酸、進行攪拌，用0.45um的PVDF針頭過濾器過濾，使用沃特世（Waters）公司的Alliance HPLC-FLD分析裝置進行分析，其結果示於下述表4中。The filter tips for smoking products of Comparative Examples 1 to 2 and Examples 1 and 3 were used to prepare smoking products. The smoke components of the cigarette smoking machine HAUNI LX20 manual (Linear type) were collected through a Cambridge filter pad (CFP) as a smoking device. In order to extract the substances in the collected pad, 30 mL of 1% acetic acid was added, stirred, filtered with a 0.45 um PVDF needle filter, and analyzed using an Alliance HPLC-FLD analysis device from Waters. The results are shown in Table 4 below.
[表4]
如上述表4所示，可以確認與未向萊賽爾絲束中添加苯酚類減少物質的比較例3相比，向萊賽爾絲束中分散苯酚類減少物質（具體地，TEC）的比較例1和實施例1的苯酚類轉移量顯著減少。另外，可以確認，與過濾嘴部包裝紙30b由一般硬卷紙製成的比較例1相比，過濾嘴部包裝紙30b由耐油性硬卷紙製成的實施例1的苯酚類轉移量與比較例1相比進一步減少。也就是說，可以確認當向過濾嘴部20中添加苯酚類減少物質（具體地，TEC）時，與不添加的情況相比，苯酚類減少效果增加，並且當將過濾嘴部20用由耐油性硬卷紙製成的過濾嘴部包裝紙30b包裹時，苯酚類減少效果更優異。另外，可以確認，苯酚類減少物質（具體地，TEC）的添加量更高的實施例3與實施例1相比，苯酚類減少效果更優異。As shown in Table 4, it can be confirmed that the amount of phenol transfer in Comparative Example 1 and Example 1 in which phenol-reducing substances (specifically, TEC) were dispersed in the lyocell tow was significantly reduced compared to Comparative Example 3 in which the phenol-reducing substances were not added to the lyocell tow. In addition, it can be confirmed that the amount of phenol transfer in Example 1 in which the filter nozzle wrapping paper 30b was made of oil-resistant hard paper was further reduced compared to Comparative Example 1 in which the filter nozzle wrapping paper 30b was made of general hard paper. That is, it was confirmed that when the phenol-reducing substance (specifically, TEC) was added to the filter 20, the phenol-reducing effect was increased compared to the case where no phenol-reducing substance was added, and when the filter 20 was wrapped with the filter wrapping paper 30b made of oil-resistant hard paper, the phenol-reducing effect was more excellent. In addition, it was confirmed that Example 3, in which the amount of phenol-reducing substance (specifically, TEC) added was higher, had a more excellent phenol-reducing effect than Example 1.
這意味著，與過濾嘴部包裝紙30b由一般硬卷紙製成的情況相比，當過濾嘴部包裝紙30b由耐油性硬卷紙製成時，從萊賽爾絲束向硬卷紙轉移的苯酚類減少物質的量減少，使得殘留在萊賽爾絲束上的苯酚類減少物質最優化，因此可以預測苯酚類減少效果優異。This means that, compared with the case where the filter nozzle wrapping paper 30b is made of general hard tissue paper, when the filter nozzle wrapping paper 30b is made of oil-resistant hard tissue paper, the amount of phenol reducing substances transferred from the lyocell bundle to the hard tissue paper is reduced, so that the phenol reducing substances remaining on the lyocell bundle are optimized, and therefore it can be predicted that the phenol reducing effect is excellent.

實驗例3：根據苯酚類減少物質的添加和過濾嘴部包裝紙的耐油處理的用於吸菸製品的過濾嘴的硬度評價Experimental Example 3: Evaluation of the hardness of filters for smoking products based on the addition of phenol-reducing substances and oil-resistant treatment of the filter wrapping paper
使用上述比較例3至4和實施例4的用於吸菸製品的過濾嘴來製備吸菸製品，測定所製備的用於吸菸製品的過濾嘴的硬度，其結果示於下述表5中。 [計算式1] 過濾嘴硬度（%）=[D-a]/D×100The filter tips for smoking products of Comparative Examples 3 to 4 and Example 4 were used to prepare smoking products, and the hardness of the prepared filter tips for smoking products was measured. The results are shown in Table 5 below.[Calculation formula 1]Filter tip hardness (%) = [D-a]/D×100
其中，D為過濾嘴直徑（mm），a表示用300g的錘下降（過濾嘴被按壓）的距離（mm）。計算上述香菸過濾嘴的硬度所需的測定值可以使用本技術領域中常用的裝置來獲得，例如，可以使用Filtrona公司的DHT 200TM。在測定硬度時，所施加的力量是考慮實際吸菸者握住香菸時所施加的力量的。通過根據本發明的一具體實施例的捲菸過濾嘴獲得的85%以上的硬度值是在通過使用作為環保材料的萊賽爾絲束確保可替代現有的由醋酸纖維素構成的捲菸過濾嘴的水平的硬度的方面有技術意義。Wherein, D is the diameter of the filter (mm), and a represents the distance (mm) that a 300g hammer descends (the filter is pressed). The measurement value required to calculate the hardness of the above-mentioned cigarette filter can be obtained using a device commonly used in the technical field, for example, DHT 200TM of Filtrona can be used. When measuring the hardness, the force applied is the force applied by an actual smoker when holding a cigarette. The hardness value of 85% or more obtained by the cigarette filter according to a specific embodiment of the present invention is technically significant in ensuring a level of hardness that can replace the existing cigarette filter composed of cellulose acetate by using lyocell tow as an environmentally friendly material.
[表5]
如上述表5所示，可以確認，與過濾嘴部包裝紙30b由一般硬卷紙製成的比較例4相比，過濾嘴部包裝紙30b由耐油性硬卷紙製成的實施例4的用於吸菸製品的過濾嘴的硬度更高。另外，可以確認，向萊賽爾絲束添加苯酚類減少物質的實施例4與未向萊賽爾絲束添加苯酚類減少物質的比較例3保持相類似的硬度。As shown in Table 5, it can be confirmed that the filter for smoking products of Example 4, in which the filter mouth wrapping paper 30b is made of oil-resistant hard wrapping paper, has a higher hardness than that of Comparative Example 4, in which the filter mouth wrapping paper 30b is made of general hard wrapping paper. In addition, it can be confirmed that Example 4, in which a phenol-reducing substance is added to a lyocell bundle, maintains a hardness similar to that of Comparative Example 3, in which a phenol-reducing substance is not added to a lyocell bundle.
