Description
本發明是關於一種吸煙物品用的紙及吸煙物品。 The present invention relates to a paper for a smoking article and a smoking article.
吸煙物品,例如附濾嘴的香煙,係具備:用捲紙捲裝煙草絲而成的煙桿;以及用濾嘴捲取紙捲裝濾嘴材而成的濾嘴。香煙是例如具有使煙桿與濾嘴對接,並且用外層紙將其對接部附近的煙桿的外周面及濾嘴的外周面捲裝並接合的構造。 A smoking article, such as a cigarette with a filter, includes: a tobacco rod formed by wrapping shredded tobacco with a paper; and a filter formed by wrapping a filter material with a filter paper. Cigarettes have, for example, a structure in which a rod and a filter are butted together, and the outer peripheral surface of the rod and the outer peripheral surface of the filter in the vicinity of the butted portion are wrapped and joined by an outer layer paper.
在吸煙物品的吸煙時,於由吸煙者吸嚐的主流煙當中可能含有不必要的化學成分,例如一氧化碳、以甲醛為代表的低級醛類、氮氧化物、焦油等的成分。為了去除這些成分,一般是使濾嘴材或捲紙等吸煙物品用的紙含有吸附劑或觸媒之類的填充劑粒子。 During smoking of smoking articles, the mainstream cigarette smoked by the smoker may contain unnecessary chemical components, such as carbon monoxide, lower aldehydes represented by formaldehyde, nitrogen oxides, tar and other components. In order to remove these components, filler particles such as adsorbents and catalysts are generally contained in paper for smoking articles such as filter materials and wrapping papers.
專利文獻1揭示一種吸煙物品,其為了減少肉眼可見的副流煙,且同時帶來經過改質的煙灰,而含有金屬氧化物或碳酸鹽。 Patent Document 1 discloses a smoking article containing a metal oxide or carbonate in order to reduce sidestream smoke visible to the naked eye and to bring in modified soot at the same time.
專利文獻1:國際公開2012/133797號公報 Patent Document 1: International Publication No. 2012/133797
吸附劑及觸媒一般是一次粒子的平均粒徑越小,比表面積越為增加,其吸附及分解的效果越為增加。因此,在添加於捲紙等吸煙物品用的紙而經抄紙的吸附劑或觸媒當中也期望使用平均粒徑更小的填充劑粒子,以便能夠更有效地去除主流煙中不必要的化學成分,例如一氧化碳、以甲醛為代表的低級醛類、氮氧化物、焦油等的成分。 For adsorbents and catalysts, the smaller the average particle size of the primary particles, the more the specific surface area increases, and the more the effect of adsorption and decomposition increases. Therefore, it is desirable to use filler particles with a smaller average particle size in the paper-made adsorbent or catalyst added to the paper for smoking articles such as wrapping paper, so that unnecessary chemical components in mainstream cigarettes can be removed more effectively , such as carbon monoxide, lower aldehydes represented by formaldehyde, nitrogen oxides, tar and other components.
然而,習知的捲紙等吸煙物品用的紙,若使用一次粒子的平均粒徑小的填充劑粒子,會有在紙的製造步驟中填充劑粒子容易脫落的問題。 However, in conventional paper for smoking articles such as wrapping paper, when filler particles having a small average particle diameter of primary particles are used, the filler particles tend to fall off during the paper production process.
本實施形態之目的在於提供一種吸煙物品用的紙,可去除主流煙中不必要的化學成分,且可在製造時抑制填充劑粒子的脫落,使產率提升。 An object of the present embodiment is to provide a paper for smoking articles, which can remove unnecessary chemical components in mainstream smoke, and can suppress the falling off of filler particles during manufacture, thereby improving the productivity.
根據本實施形態,提供一種吸煙物品用的紙,其特徵為含有纖維素纖維,且以添加纖維素奈米纖維及一次粒子的平均粒徑為1μm以下之作為吸附劑或觸媒的填充劑粒子之方式經抄紙者。 According to the present embodiment, there is provided a paper for smoking articles characterized by containing cellulose fibers, adding cellulose nanofibers and filler particles having an average particle size of primary particles of 1 μm or less as adsorbents or catalysts The way by the paper maker.

以下,針對實施形態之吸煙物品用的紙詳加說明。 Hereinafter, the paper for smoking articles of the embodiment will be described in detail.
本實施形態之吸煙物品用的紙係含有纖維素纖維,且以添加纖維素奈米纖維及一次粒子的平均粒徑為1μm以下之作為吸附劑或觸媒的填充劑粒子之方式經抄紙者。 The paper for the smoking article of the present embodiment contains cellulose fibers and is made by adding cellulose nanofibers and filler particles having an average particle size of primary particles of 1 μm or less as adsorbents or catalysts.
一般而言,紙可藉由使纖維素纖維懸浮的濕紙之抄製重組以及乾燥來抄紙。濕紙中,纖維素纖維間係經由水分子形成有鬆緩的氫鍵,而隨著乾燥使纖維素纖維彼此逐漸接近。結果,乾燥後的紙,使纖維素纖維彼此直接透過氫鍵而接合。 In general, paper can be made by reconstituting and drying a wet paper in which cellulosic fibers are suspended. In wet paper, loose hydrogen bonds are formed between cellulose fibers via water molecules, and the cellulose fibers gradually approach each other as they dry. As a result, in the dried paper, the cellulose fibers are directly bonded to each other through hydrogen bonds.
另一方面,若對濕紙再添加填充劑粒子來加以抄紙,則填充劑粒子會妨礙纖維素纖維間的氫鍵的形成。結果,經添加填充劑粒子來加以抄紙的紙,比起經無添加填充劑粒子來加以抄紙的紙,纖維素纖維彼此的直接的接合較弱,使纖維素纖維間的空隙增加。因此,經添加 填充劑粒子來加以抄紙的紙,會有在製造時填充劑粒子容易脫落,使拉伸強度降低,而使透氣度增加的傾向。然而,捲紙等吸煙物品用的紙,為了不破壞風味和口感,且具有香煙製造時所要求的強度及操作性,而要求使透氣度及拉伸強度設在適當的範圍,因此添加填充劑粒子,且在要抄紙的紙中必須抑制透氣度的增加及拉伸強度的降低。這些問題在抄紙時要添加的填充劑粒子的一次粒子的平均粒徑越小,或填充劑粒子的量越多就越為顯著。 On the other hand, if filler particles are added to wet paper for papermaking, the filler particles hinder the formation of hydrogen bonds between cellulose fibers. As a result, the paper made by adding filler particles is weaker than the paper made by adding no filler particles, and the direct bonding of cellulose fibers is weaker, and the voids between the cellulose fibers are increased. Therefore, in the paper made by adding filler particles, the filler particles tend to fall off during production, thereby reducing the tensile strength and increasing the air permeability. However, paper for smoking articles such as wrapping paper is required to have the air permeability and tensile strength in an appropriate range in order not to spoil the flavor and texture, and to have the strength and handleability required for the manufacture of cigarettes, so fillers are added. particles, and it is necessary to suppress the increase in air permeability and the decrease in tensile strength in the paper to be made into paper. These problems become more conspicuous when the average particle diameter of the primary particles of the filler particles to be added at the time of papermaking is smaller or the amount of the filler particles is larger.
此外,為了防止填充劑粒子的脫落,可考慮對濕紙再添加增黏多糖類(polysaccharide thickener)等的結合劑後進行抄紙,但是會有結合劑覆蓋填充劑粒子的表面而使作為吸附劑或觸媒的功能降低的傾向,因此並不理想。 In addition, in order to prevent the falling off of the filler particles, it may be considered to add a binder such as polysaccharide thickener to the wet paper and then make paper, but the binder may cover the surface of the filler particles and be used as an adsorbent or an adsorbent. Since the function of the catalyst tends to decrease, it is not preferable.
本實施形態之吸煙物品用的紙,係對濕紙除添加填充劑粒子之外,又添加纖維素奈米纖維來加以抄紙者。這種紙是透過使纖維素奈米纖維利用氫鍵接合俾使纖維素纖維間橋接,藉此可補強纖維素纖維間的氫鍵。因此,添加填充劑粒子及纖維素奈米纖維來加以抄紙的紙比起僅添加填充劑粒子來加以抄紙的紙,較抑制紙的拉伸強度的降低。而且,由於纖維素奈米纖維的存在,使纖維素纖維間的空隙縮小,因此抑制紙的透氣度的增加,使得製造時填充劑粒子不容易脫落,而使產率提升。此外,由於纖維素奈米纖維並不會覆蓋填充劑粒子的表面,因此不會妨礙填充劑粒子之作為吸附劑或觸媒的效果。亦即,本實 施形態之吸煙物品用的紙係纖維素纖維與纖維素奈米纖維的混合抄紙,並且在其內部擔載有填充劑粒子的紙。 The paper for smoking articles of the present embodiment is made by adding cellulose nanofibers to wet paper in addition to filler particles. This paper can strengthen the hydrogen bonds between cellulose fibers by making cellulose nanofibers use hydrogen bonding to bridge the cellulose fibers. Therefore, the paper made by adding filler particles and cellulose nanofibers is more restrained from lowering the tensile strength of the paper than the paper made by adding only filler particles. Moreover, the presence of cellulose nanofibers reduces the voids between the cellulose fibers, thereby suppressing the increase in the air permeability of the paper, making it difficult for the filler particles to fall off during production, and improving the productivity. In addition, since the cellulose nanofibers do not cover the surface of the filler particles, they will not hinder the effect of the filler particles as adsorbents or catalysts. That is, the paper-based cellulose fiber and cellulose nanofibers for the smoking article of the present embodiment are paper-made, and the filler particles are supported in the paper.
根據本實施形態之吸煙物品用的紙,即使是使用平均粒徑較小的填充劑粒子,亦抑制製造時的填充劑粒子的脫落。因此,本實施形態之吸煙物品用的紙比起習知者,可在抄紙時使平均粒徑更小的填充劑粒子更大量地被添加。結果,根據本實施形態之吸煙物品用的紙,便可更有效地去除主流煙中不必要的化學成分,例如一氧化碳、以甲醛為代表的低級醛類、氮氧化物、焦油等的成分。而且,由於可抑制透氣度的增加及拉伸強度的降低,因此可依吸煙物品用的紙所需的物性調節這些。 According to the paper for smoking articles of the present embodiment, even if filler particles having a small average particle diameter are used, the dropping of filler particles during production is suppressed. Therefore, the paper for the smoking article of the present embodiment can be added in a larger amount of filler particles having a smaller average particle diameter at the time of papermaking than the conventional one. As a result, according to the paper for smoking articles of the present embodiment, unnecessary chemical components such as carbon monoxide, lower aldehydes represented by formaldehyde, nitrogen oxides, and tar in mainstream smoke can be removed more effectively. Furthermore, since the increase in air permeability and the decrease in tensile strength can be suppressed, these can be adjusted according to the physical properties required for the paper for smoking articles.
以下,針對纖維素纖維、纖維素奈米纖維及填充劑粒子詳加說明。 Hereinafter, cellulose fibers, cellulose nanofibers, and filler particles will be described in detail.
纖維素纖維沒有特別的限定,例如可使用一般吸煙物品的捲紙所使用的針葉樹紙漿纖維或是闊葉樹紙漿纖維等的木材紙漿纖維、亞麻紙漿纖維、大麻紙漿纖維、或是瓊麻紙漿纖維等、或是這些的混合物。例如吸煙物品用的紙當中,為了確保透氣度,同時抑制拉伸強度的降低,最好含有10gsm至40gsm的纖維素纖維。纖維素纖維是例如使屬於體積平均纖維長度1478μm的亞麻紙漿纖維打漿成肖伯爾.瑞格勒濾水度為60°SR來使用。 Cellulose fibers are not particularly limited, and for example, wood pulp fibers, flax pulp fibers, hemp pulp fibers, or hemp pulp fibers, such as conifer pulp fibers used in general smoking articles, or hardwood pulp fibers, can be used. or a mixture of these. For example, in the paper for smoking articles, it is preferable to contain cellulose fibers of 10 gsm to 40 gsm in order to ensure the air permeability and suppress the decrease of the tensile strength. Cellulose fibers are, for example, made by beating flax pulp fibers with a volume average fiber length of 1478 μm into Schubert. Regler water filtration degree is 60°SR for use.
纖維素奈米纖維是平均纖維直徑D為1μm以下,纖維長度L滿足L/D>100的纖維。纖維素奈米纖維的平均纖維直徑為例如5nm至500nm,更佳為5nm至50nm。纖維素奈米纖維為2重量%水溶液的黏度是例如500mPas至8000mPas,較佳為1000mPas以上,更佳為6000mPas至8000mPas。纖維素奈米纖維的水溶液的黏度是纖維素奈米纖維的平均纖維長度越長越為增加,因此被用來作為纖維素奈米纖維的平均纖維長度的基準。該黏度是利用旋轉式黏度測量法在25℃、旋轉速度60rpm下的測量值。這種纖維素奈米纖維的例子可舉出杉野機械股份有限公司製造的生質材料奈米纖維的BiNFi-s(註冊商標)。 Cellulose nanofibers are fibers whose average fiber diameter D is 1 μm or less and fiber length L satisfies L/D>100. The average fiber diameter of the cellulose nanofibers is, for example, 5 nm to 500 nm, more preferably 5 nm to 50 nm. The viscosity of the 2 wt% aqueous solution of the cellulose nanofibers is, for example, 500 mPas to 8000 mPas, preferably 1000 mPas or more, more preferably 6000 mPas to 8000 mPas. The viscosity of the aqueous solution of cellulose nanofibers increases as the average fiber length of the cellulose nanofibers increases, so it is used as a benchmark for the average fiber length of the cellulose nanofibers. The viscosity is a value measured by rotational viscometry at 25° C. and a rotational speed of 60 rpm. Examples of such cellulose nanofibers include BiNFi-s (registered trademark) of biomass material nanofibers manufactured by Sugino Machinery Co., Ltd.
纖維素奈米纖維的製作方法沒有特別的限定,可利用同業者已知的製作方法來製作。長纖維的纖維素奈米纖維的製作方法可例舉出高分子相互排列體纖維法、剝離型複合紡紗法、改良型習知式紡紗法、超延伸(super draw)法、及雷射延伸法。短纖維的纖維素奈米纖維的製作法可例舉出熔融流動法(噴射紡紗法)、閃式紗法(flash spinning)、打漿法、混合紡紗法、沾黏紡紗法、氣泡片化法、細菌法(bacterial method)、金屬核烴高溫加熱法、鑄模法、及電解紡紗法。 The production method of the cellulose nanofibers is not particularly limited, and can be produced by a production method known to those in the industry. The production methods of long-fiber cellulose nanofibers include the polymer inter-array fiber method, the exfoliation composite spinning method, the modified conventional spinning method, the super draw method, and the laser method. extension method. The production method of short-fiber cellulose nanofibers includes a melt flow method (jet spinning method), a flash spinning method, a beating method, a hybrid spinning method, a stick spinning method, and a bubble sheeting method. Chemical method, bacterial method (bacterial method), metal nuclear hydrocarbon high temperature heating method, casting method, and electrospinning method.
吸煙物品用的紙當中,添加纖維素奈米纖維來加以抄紙,例如可使用掃描型電子顯微鏡(SEM)分析吸煙物品用的紙來判定。 Among the papers for smoking articles, cellulose nanofibers are added to make paper, and it can be determined by analyzing the papers for smoking articles using, for example, a scanning electron microscope (SEM).
填充劑粒子是觸媒或吸附劑,是分解或吸附主流煙中所含的不必要的化學成分者。觸媒例如可使用金屬氧化物、金屬氫氧化物等,金屬氧化物、金屬氫氧化物可使用從B、Al、Si、Ti、Fe、Co、Ni、Cu、Zn、Ge、Zr、Nb、Mo、Ru、Rh、Pd、Ag、Sn、Ce、Hf、Ta、W、Re、Os、Ir、Pt及Au所構成之群組中選擇的至少一個金屬元素的氧化物或是氫氧化物。吸附劑可例舉出多孔性材料、離子交換樹脂、黏土礦物,特別理想的例子是從活性碳、二氧化矽、氧化鋁、氧化鈦、鋁矽酸鹽、沸石、中孔洞二氧化矽、水滑石、海泡石以及這些的組合所構成之群組中選擇。 The filler particles are catalysts or adsorbents that decompose or adsorb unnecessary chemical components contained in mainstream smoke. For example, metal oxides, metal hydroxides, etc. can be used as catalysts, and metal oxides and metal hydroxides can be used from B, Al, Si, Ti, Fe, Co, Ni, Cu, Zn, Ge, Zr, Nb, An oxide or hydroxide of at least one metal element selected from the group consisting of Mo, Ru, Rh, Pd, Ag, Sn, Ce, Hf, Ta, W, Re, Os, Ir, Pt and Au. The adsorbent can be exemplified by porous materials, ion exchange resins, clay minerals, particularly desirable examples are activated carbon, silica, alumina, titania, aluminosilicate, zeolite, mesoporous silica, water Choose from the group consisting of talc, sepiolite, and combinations of these.
水滑石類化合物具有層狀結晶堆疊的構造,可用以下一般式來表示:M2+ 1-xM3+ x(OH)2(An-)x/n.mH2O(此處的M2+是從Mg、Zn、Ni及Ca所構成之群組中選擇的二價金屬離子,M3+是Al離子,An-是從CO3、SO4、OOC-COO、Cl、Br、F、Fe(CN)63-、Fe(CN)64-、酞酸、異酞酸、對苯二甲酸、馬來酸、烯基酸及其誘導體、蘋果酸、水楊酸、丙烯酸、己二酸、琥珀酸、檸檬酸以及磺酸所構成之群組中選擇的n價陰離子(anion),且0.1<x<0.4,0<m<2)。 The hydrotalcite compound has the structure of layered crystal stacking, which can be represented by the following general formula: M 2+ 1-x M 3+ x (OH) 2 (A n- ) x/n . mH 2 O (here, M 2+ is a divalent metal ion selected from the group consisting of Mg, Zn, Ni and Ca, M 3+ is Al ion, An- is selected from CO 3 , SO 4 , OOC-COO, Cl, Br, F, Fe(CN)6 3- , Fe(CN)6 4- , phthalic acid, isophthalic acid, terephthalic acid, maleic acid, alkenyl acid and their derivatives, n-valent anion (anion) selected from the group consisting of malic acid, salicylic acid, acrylic acid, adipic acid, succinic acid, citric acid and sulfonic acid, and 0.1<x<0.4, 0<m<2).
填充劑粒子的一次粒子的平均粒徑(中位直徑(d50))為1μm以下,較佳為10nm至500nm,更佳為10nm至100nm。填充劑粒子的一次粒子的平均粒徑若更小,則使填充劑粒子的比表面積增加,使填充劑粒子所吸附或分 解主流煙中不必要的化學成分的效果提升,因此相當理想。另一方面,填充劑粒子的一次粒子的平均粒徑若未滿10μm,則填充劑粒子容易在製造吸煙物品用的紙時飛散,因此並不理想。此外,所謂「一次粒子」表示從外觀上的幾何學形態判斷為單位粒子者,相對的,所謂「二次粒子」表示多數個一次粒子聚集而形成的集合體。 The average particle diameter (median diameter (d 50 )) of the primary particles of the filler particles is 1 μm or less, preferably 10 nm to 500 nm, more preferably 10 nm to 100 nm. If the average particle diameter of the primary particles of the filler particles is smaller, the specific surface area of the filler particles is increased, and the effect of adsorbing or decomposing unnecessary chemical components in the mainstream smoke is enhanced by the filler particles, which is desirable. On the other hand, if the average particle diameter of the primary particles of the filler particles is less than 10 μm, the filler particles are likely to be scattered when manufacturing paper for smoking articles, which is not preferable. In addition, the term "primary particle" refers to a unit particle determined from the geometrical appearance of the appearance, while the term "secondary particle" refers to an aggregate formed by agglomeration of a plurality of primary particles.
填充劑粒子例如在吸煙物品用的紙當中含有2重量%至60重量%為佳,更佳為含有10重量%至45重量%,尤佳為含有25重量%至35重量%。填充劑粒子的基重若未滿2重量%,則依填充劑粒子的種類,使填充劑所吸附或分解主流煙中不必要的化學成分的效果降低,因此並不理想。填充劑粒子的量若超過60重量%,則吸煙物品用的紙的拉伸強度降低,透氣度增加,因此有變成不適合作為吸煙物品用的紙的物性的傾向,因此並不理想。又,填充劑粒子例如在吸煙物品用的紙當中含有2gsm至40gsm為佳,更佳為含有10gsm至40gsm。 The filler particles are preferably contained in 2 to 60 wt %, more preferably 10 to 45 wt %, and particularly preferably 25 to 35 wt % in the paper for smoking articles, for example. If the basis weight of the filler particles is less than 2% by weight, depending on the type of filler particles, the effect of adsorbing or decomposing unnecessary chemical components in the mainstream smoke by the filler is reduced, which is not preferable. When the amount of filler particles exceeds 60 wt %, the tensile strength of the paper for smoking articles decreases, and the air permeability increases, so that the physical properties of the paper for smoking articles tend to be unsuitable, which is not preferable. Moreover, as for the filler particle, it is preferable to contain 2 gsm to 40 gsm in the paper for smoking articles, for example, and it is more preferable to contain 10 gsm to 40 gsm.
吸煙物品用的紙的透氣度例如為10CORESTA單位至500CORESTA單位,更佳為10CORESTA單位至100CORESTA單位。本說明當中所謂的透氣度是紙的兩面的差壓為100mmH2O時,以ml.cm2/min的單位來表示通過面積1cm2的氣體的流量者。1ml.cm2/min是1CORESTA單位(1C.U.)。若將吸煙物品用的紙的透氣度設為未滿10CORESTA單位,則主流煙就不容易與添加在吸煙物品用的紙後進行抄紙的填充劑粒子接觸,因此並不理 想。若吸煙物品用的紙的透氣度超過500CORESTA單位,則使用吸煙物品用的紙作為捲紙時,煙桿的燃燒速度會過度增加,因此並不理想。 The air permeability of the paper for smoking articles is, for example, 10 CORESTA units to 500 CORESTA units, and more preferably 10 CORESTA units to 100 CORESA units. The so-called air permeability in this description is when the differential pressure between the two sides of the paper is 100mmH 2 O, in ml. The unit of cm 2 /min represents the flow rate of gas passing through an area of 1 cm 2 . 1ml. cm 2 /min is 1 CORESTA unit (1 C.U.). If the air permeability of the paper for smoking articles is less than 10 CORESTA units, the mainstream smoke is not easily contacted with filler particles added to the paper for smoking articles and then made into paper, which is not preferable. When the air permeability of the paper for smoking articles exceeds 500 CORESTA units, when the paper for smoking articles is used as the wrapping paper, the burning speed of the cigarette rod is excessively increased, which is not preferable.
吸煙物品用的紙的拉伸強度例如以12.5N/15mm以上為佳。吸煙物品用的紙的拉伸強度若未滿12.5N/15mm,則使用吸煙物品用的紙作為捲紙或濾嘴捲取紙時,有可能會耐不住捲揚機的機械速度而斷開,因此並不理想。吸煙物品用的紙的基重例如為15gsm至100gsm,更佳為20gsm至80gsm,尤佳為40gsm至60gsm。吸煙物品用的紙的基重若在這些範圍,則使用吸煙物品用的紙作為捲紙或濾嘴捲取紙時就不易斷開,並且可配合煙草絲或濾嘴材的形狀捲裝起來,因此相當理想。 The tensile strength of the paper for smoking articles is preferably 12.5 N/15 mm or more, for example. If the tensile strength of the paper for smoking articles is less than 12.5N/15mm, when the paper for smoking articles is used as the wrapping paper or filter wrapping paper, it may not be able to withstand the mechanical speed of the hoist and break. Not ideal. The basis weight of the paper for smoking articles is, for example, 15 gsm to 100 gsm, more preferably 20 gsm to 80 gsm, and still more preferably 40 gsm to 60 gsm. If the basis weight of the paper for smoking articles is in these ranges, when the paper for smoking articles is used as the wrapping paper or filter wrapping paper, it is not easy to break, and it can be wrapped according to the shape of the tobacco shreds or the filter material. So quite ideal.
此外,吸煙物品用的紙除了纖維素纖維、纖維素奈米纖維及填充劑粒子以外,亦可含有香料、燃燒調節劑、著色劑等各種添加劑。 In addition to cellulose fibers, cellulose nanofibers, and filler particles, the paper for smoking articles may contain various additives such as flavors, combustion modifiers, and colorants.
吸煙物品用的紙的抄紙法沒有特別的限定,可利用同業紙已知的抄紙法來製作。抄紙法一般包含紙抄製步驟、及使其乾燥的步驟。抄紙機可使用以往眾所周知者,例如圓網抄紙機、傾斜短網抄紙機、長網抄紙機、短網抄紙機等,可依要求特性適當組合抄紙機。紙抄製步驟所使用的濕試料例如可對使纖維素纖維打漿成肖伯爾.瑞格勒濾水度為60°SR而調製的漿料,添加預定量的填充劑粒子及纖維素奈米纖維來調製。經抄製的濕紙可利用以往眾所周知的乾燥方法,例如楊克式烘缸(yankee dryer)、 多筒式、熱風式、紅外線加熱式等來乾燥。濕紙例如可用100℃至150℃的溫度使其乾燥。 The papermaking method of the paper for smoking articles is not particularly limited, and it can be produced by a known papermaking method in the industry. The papermaking method generally includes a papermaking step and a drying step. As the paper machine, those known in the past can be used, such as rotary wire paper machine, inclined short wire paper machine, Fourdrinier wire paper machine, short wire paper machine, etc. The paper machine can be appropriately combined according to the required characteristics. The wet sample used in the papermaking step can be used, for example, to beat the cellulose fibers into Schubert. The slurry prepared with Regler water freeness of 60°SR was prepared by adding a predetermined amount of filler particles and cellulose nanofibers. The sheeted wet paper can be dried by a conventionally known drying method, for example, a yankee dryer, a multi-cylinder type, a hot air type, an infrared heating type, and the like. The wet paper can be dried, for example, at a temperature of 100°C to 150°C.
此外,吸煙物品用的紙是相對於纖維素纖維、纖維素奈米纖維及填充劑粒子的總重量,較佳為添加2重量%至32重量%的纖維素奈米纖維,更加為4重量%至13重量%來加以抄紙者。抄紙時的纖維素奈米纖維的添加量若是上述數值範圍,則可有效抑制填充劑粒子在製造時的脫落。 In addition, the paper for smoking articles is preferably 2 to 32% by weight of cellulose nanofibers, more preferably 4% by weight, relative to the total weight of cellulose fibers, cellulose nanofibers and filler particles. to 13% by weight to be a papermaker. The addition amount of the cellulose nanofibers at the time of papermaking is within the above-mentioned numerical range, and the dropping of the filler particles during production can be effectively suppressed.
上述吸煙物品用的紙被用來作為構成如第1圖所示的吸煙物品的各種紙,可獲得效果。在此,作為吸煙物品之一例,針對附濾嘴的香煙加以說明,但是亦可為不具濾嘴的構造。吸煙物品亦可為其他的吸煙物品,例如雪茄、小雪茄等。雪茄、小雪茄等的情況,在利用繩索將填充料捲起來之前或利用繩索捲起來之後構成皆可。 The above-mentioned paper for smoking articles is used as various papers constituting the smoking article as shown in FIG. 1, and effects can be obtained. Here, as an example of the smoking article, a filter-attached cigarette will be described, but it may be a structure without a filter.

以下,說明(1)至(3)各試驗的測量方法。 Hereinafter, the measurement methods of each of the tests (1) to (3) will be described.
填充劑粒子的產率的測量是使用熱風循環式乾燥器(光洋熱系統股份有限公司製造、KLO-60M(商品名))來測量。首先,將各試驗樣本放置在設定為105℃的熱風循環式乾燥器內12個小時使其乾燥,並測量紙的乾燥重量。接下來,透過從該紙的乾燥重量減掉抄紙時的纖維素纖維及纖維素奈米纖維的添加量,算出紙中的填充劑粒子的含量。產率可由以下式子算出。 The yield of filler particles was measured using a hot air circulation dryer (manufactured by Koyo Thermal Systems Co., Ltd., KLO-60M (trade name)). First, each test sample was placed in a hot air circulating dryer set at 105° C. for 12 hours to be dried, and the dry weight of the paper was measured. Next, the content of filler particles in the paper was calculated by subtracting the added amounts of cellulose fibers and cellulose nanofibers at the time of papermaking from the dry weight of the paper. The yield can be calculated from the following formula.
產率(%)=填充劑粒子的含量/抄紙時的填充劑粒子的添加量×100 Yield (%)=content of filler particles/addition amount of filler particles during papermaking×100
透氣度的測量是依據Coresta method No.3記載的方法,使用透氣度測量裝置(Borfwaldt公司製造、Air Permeability Tester A20(商品名))來測量。透氣度是紙的兩面的差壓為100mmH2O時,以ml.cm2/min的單位來表示通過面積1cm2的氣體的流量。1ml.cm2/min是1CORESTA單位(1C.U.)。 The measurement of the air permeability was performed according to the method described in Coresta method No. 3 using an air permeability measuring device (manufactured by Borfwaldt, Air Permeability Tester A20 (trade name)). Air permeability is when the differential pressure on both sides of the paper is 100mmH 2 O, in ml. The unit of cm 2 /min represents the flow rate of gas passing through an area of 1 cm 2 . 1ml. cm 2 /min is 1 CORESTA unit (1 C.U.).
拉伸強度的測量是依據JIS P 8113,使用拉伸強度測量裝置(東洋精機股份有限公司製造、STRONGRAPH E3-L (商品名))來測量。將各試驗樣本裁切成寬15mm、長200mm,以拉伸強度200mm/分鐘拉長,將斷開時的荷重設為拉伸強度的值。 The measurement of the tensile strength was performed according to JIS P 8113, using a tensile strength measuring device (manufactured by Toyo Seiki Co., Ltd., STRONGRAPH E3-L (trade name)). Each test sample was cut into a width of 15 mm and a length of 200 mm, stretched at a tensile strength of 200 mm/min, and the load at the time of breaking was set as the value of the tensile strength.
針對實施例1至16及比較例1至6的試驗樣本的測量結果加以說明。 The measurement results of the test samples of Examples 1 to 16 and Comparative Examples 1 to 6 will be described.
第1表當中,將抄紙時對纖維素纖維添加填充劑粒子及纖維素奈米纖維的實施例1至4、與僅添加填充劑粒子的比較例1加以比較。相對於比較例1當中47%的產率,實施例1至4的填充劑粒子的產率顯示出72%至92%較高的值。相對於比較例1當中164C.U.的透氣度,實施例1至4的透氣度顯示出55.7C.U.至120C.U.較低的值。又,相對於比較例1當中17.9N/15mm的拉伸強度,實施例1至4的拉伸強度顯示出19.4N/15mm至24.8N/15mm較高的值。又,相對於比較例1當中21.8重量%的填充劑粒子的含量,實施例1至4顯示出28.7重量%至33.2重量%較高的值。從這些結果可知,實施例1至4添加了纖維素奈米纖維,因此與比較例1相比,填充劑粒子的產率提升,透氣度降低,拉伸強度增加。並且,實施例1至4與比較例1相比,更大量地添加平均粒徑小的填充劑粒子並進行抄紙,因此可更有效地去除主流煙中不必要的化學成分,也就是一氧化碳、以甲醛為代表的低級醛類、氮氧化物、焦油等的成分。與此同樣的結果也可從填充劑粒子的添加 量與第1表不同的第2至4表來獲得。 In Table 1, Examples 1 to 4 in which filler particles and cellulose nanofibers were added to cellulose fibers during papermaking were compared with Comparative Example 1 in which only filler particles were added. Relative to the yield of 47% in Comparative Example 1, the yields of filler particles of Examples 1 to 4 showed higher values of 72% to 92%. Relative to the air permeability of 164 C.U. in Comparative Example 1, the air permeability of Examples 1 to 4 showed lower values of 55.7 C.U. to 120 C.U. Moreover, with respect to the tensile strength of 17.9 N/15mm in the comparative example 1, the tensile strengths of Examples 1 to 4 showed high values of 19.4 N/15 mm to 24.8 N/15 mm. In addition, with respect to the content of filler particles in Comparative Example 1 of 21.8 wt %, Examples 1 to 4 showed high values of 28.7 wt % to 33.2 wt %. From these results, it can be seen that in Examples 1 to 4, cellulose nanofibers are added, and therefore, compared with Comparative Example 1, the yield of filler particles is improved, the air permeability is decreased, and the tensile strength is increased. In addition, in Examples 1 to 4, compared with Comparative Example 1, a larger amount of filler particles having a smaller average particle diameter was added and papermaking was performed, so that unnecessary chemical components in mainstream smoke, that is, carbon monoxide, carbon monoxide, and Formaldehyde is a component of lower aldehydes, nitrogen oxides, tar and the like. Similar results can be obtained from Tables 2 to 4 in which the amount of filler particles added is different from that in Table 1.
第1表當中,將抄紙時的纖維素奈米纖維的添加量為3.58重量%的實施例1、與12.94重量%的實施例2加以比較。實施例2當中,由於抄紙時的纖維素奈米纖維的添加量多,因此與實施例1相比,已知填充劑的產率提升,透氣度減少,拉伸強度也增加。與此同樣的結果也可從填充劑粒子的添加量與第1表不同的第2至4表的結果來獲得。 In Table 1, Example 1 in which the amount of cellulose nanofibers added during papermaking was 3.58% by weight and Example 2 in which it was 12.94% by weight were compared. In Example 2, since the amount of cellulose nanofibers added during papermaking is large, compared with Example 1, it is known that the yield of the filler is improved, the air permeability is decreased, and the tensile strength is also increased. The same results can be obtained from the results in Tables 2 to 4 in which the amount of filler particles added is different from that in Table 1.
第1表當中,將抄紙時所添加的纖維素奈米纖維為FMa-10002的實施例1、與IMa-10002的實施例3加以比較。根據該結果,比起實施例1所使用的2重量%水溶液的黏度為700mPa.s的FMa-10002,已知實施例3所使用的2重量%水溶液的黏度為7500mPa.s的IMa-10002使產率提升,使透氣度降低,使拉伸強度增加的效果較高。與第1表的結果同樣地,從填充劑粒子的添加量不同的第2至4表的結果也獲得了同樣的結果。 In Table 1, Example 1 in which the cellulose nanofibers added during papermaking were FMa-10002 and Example 3 in which IMa-10002 were used were compared. According to this result, the viscosity of the 2 wt % aqueous solution used in Example 1 was 700 mPa. s FMa-10002, the viscosity of the 2 wt % aqueous solution used in known Example 3 is 7500 mPa. The IMa-10002 of s increases the yield, reduces the air permeability, and has a higher effect of increasing the tensile strength. Similar to the results in Table 1, the same results were obtained from the results in Tables 2 to 4 in which the amount of filler particles added was different.
如以上,本實施形態之吸煙物品用的紙由於添加有纖維素奈米纖維,因此即使含有一次粒子的平均粒徑小的填充劑粒子,也可抑制產率的降低、拉伸強度的降低、透氣的增加。並且,本實施形態之吸煙物品用的紙當中,添加了比起以往平均粒徑更小的填充劑粒子並進行抄紙,並且可含有更多的填充劑粒子,因此可構成能夠更有效地去除主流煙中不必要的化學成分的構造。 As described above, since cellulose nanofibers are added to the paper for smoking articles according to the present embodiment, even if filler particles with a small average particle diameter of primary particles are contained, a decrease in yield, a decrease in tensile strength, Increased breathability. In addition, the paper for the smoking article of the present embodiment is made by adding filler particles having a smaller average particle diameter than the conventional paper, and can contain more filler particles, so that the mainstream can be removed more effectively. Construction of unwanted chemical constituents in smoke.
