[Solution] A toilet roll manufacturing method comprises: a step for applying an activated-carbon-containing ink that includes activated carbon, an aqueous pigment, and an acrylic resin on at least one surface of paper tube base sheet; a step for forming the paper tube base sheet into a cylindrical shape; and a step for winding toilet paper base sheet onto the cylindrically shaped sheet.

Description

トイレットロールの製造方法及びトイレットロールToilet roll manufacturing method and toilet roll
　本発明は、帯状のトイレットペーパーを紙管に巻いたトイレットロールの製造方法及びそのトイレットロールに関する。 The present invention relates to a method for manufacturing a toilet roll obtained by winding a belt-like toilet paper around a paper tube, and the toilet roll.
　紙管に消臭機能を付与したトイレットロールがある。このようなトイレットロールを用いることで、トイレ空間内に据え置き型の消臭剤製品等を置く必要がなくなる。 There is a toilet roll with a deodorizing function added to the paper tube. By using such a toilet roll, there is no need to place a stationary deodorant product or the like in the toilet space.
　ところで、多孔質である活性炭は、幅広い種類の悪臭に対する消臭性を有し、消臭効果も高いことが知られる。このため、トイレットロールに消臭機能を付与するための消臭剤として利用することが期待される。 By the way, it is known that porous activated carbon has a deodorizing property against a wide variety of malodors and has a high deodorizing effect. For this reason, utilization as a deodorant for providing a deodorizing function to a toilet roll is anticipated.
　しかし、活性炭をトイレットペーパー自体に混合することは生産性及びコストの点から望ましくはない。また、活性炭は粉末であるため紙管の表面に定着しがたく、単に紙管内面に付与しただけでは、ロールホルダーとの摩擦によって剥れ落ちてしまう。 However, mixing activated carbon with the toilet paper itself is not desirable from the viewpoint of productivity and cost. Moreover, since activated carbon is a powder, it is difficult to be fixed on the surface of the paper tube, and if it is simply applied to the inner surface of the paper tube, it is peeled off by friction with the roll holder.

「トイレットロールの製造方法」
　本発明の実施形態に係るトイレットロール１０の製造方法例を、図面を参照しながら説明する。但し、本発明によるトイレットロールの製造方法は、この方法に必ずしも限定されるわけではない。 "Manufacturing method of toilet roll"
The example of the manufacturing method of the toilet roll 10 which concerns on embodiment of this invention is demonstrated referring drawings. However, the method for producing a toilet roll according to the present invention is not necessarily limited to this method.
　本実施形態のトイレットロールの製造方法は、図１に示すように、長尺の紙管３０を製造する工程（Ａ）と、その長尺の紙管を用いてログを製造するログ製造工程（Ｂ）と、ログを裁断して個々のトイレットロールにする裁断工程（Ｃ）と、を有している。 As shown in FIG. 1, the method for manufacturing a toilet roll according to this embodiment includes a step (A) of manufacturing a long paper tube 30 and a log manufacturing step of manufacturing a log using the long paper tube ( B) and a cutting step (C) for cutting the log into individual toilet rolls.
〔紙管製造工程（Ａ）〕
　本実施形態の紙管製造工程は、図１中（Ａ）及び図２に示すように、原反ロール３１Ａ，３２Ａから繰出された二枚の帯状の紙管原紙３１，３２のうち一方の紙管原紙３１の一方面に糊付けロール５１により糊を付与し、前記一方の紙管原紙３１の糊付けされた面に他方の紙管原紙３２を幅方向に一部重ね、前記他方の紙管原紙３２の糊付け面と接しない面をマンドレルシャフト５２に対向する面、すなわち紙管内面となる面にして、各紙管原紙３１，３２をマンドレルシャフト５２に螺旋状に巻き付けて連続的に筒状部分２９を形成し、その筒状部分２９をトイレットロールの複数倍幅以上の幅でカッター５８によりカットして長尺のスパイラル紙管３０（スパイラル式紙管とも称される）を形成する。このスパイラル紙管３０は、一方の紙管原紙３１が紙管外面側、他方の紙管原紙３２が紙管内面側となる態様の二層積層構造となる。なお、本実施形態では、２枚の紙管原紙３１，３２をスパイラル巻きしているが、１枚又は３枚以上の紙管原紙をスパイラル巻きして長尺の紙管を形成してもよい。 [Paper tube manufacturing process (A)]
In the paper tube manufacturing process of the present embodiment, as shown in FIG. 1A and FIG. 2, one of the two strip-shaped paper tube base papers 31 and 32 fed out from the raw rolls 31A and 32A. Glue is applied to one side of the tube base paper 31 by a gluing roll 51, and the other paper tube base paper 32 is partially overlapped in the width direction on the pasted surface of the one paper tube base paper 31. The surface that does not contact the gluing surface is the surface facing the mandrel shaft 52, that is, the surface that becomes the inner surface of the paper tube, and the paper tube base papers 31 and 32 are spirally wound around the mandrel shaft 52 to continuously form the tubular portion 29. Then, the cylindrical portion 29 is cut by a cutter 58 with a width more than a multiple of the toilet roll to form a long spiral paper tube 30 (also referred to as a spiral paper tube). The spiral paper tube 30 has a two-layer laminated structure in which one paper tube base paper 31 is on the outer side of the paper tube and the other paper tube base paper 32 is on the inner side of the paper tube. In this embodiment, the two paper tube base papers 31 and 32 are spirally wound. However, one or three or more paper tube base papers may be spirally wound to form a long paper tube. .
　紙管原紙３１，３２は、坪量が１２０～２２０ｇ／ｍ2、紙厚が１５０～５００μｍであるのが望ましい。また、紙管原紙を密度０．２～１．８ｇ／ｃｍ3、ベック平滑度１０～８０秒のものとすると活性炭含有インキ及び消臭剤薬液の浸透性がより確実なものとなり、塗工操作がしやすく、また、トイレットロールとなった際に十分な強度の紙管となる。なお、長尺の紙管３０を形成するにあたって、この他方の紙管原紙３２と対となるもう一方の紙管原紙３１は、違う原反を使用してもよく、例えば、坪量を変えたりしてもよい。 The paper tube base papers 31 and 32 preferably have a basis weight of 120 to 220 g / m 2 and a paper thickness of 150 to 500 μm. In addition, when the paper tube base paper has a density of 0.2 to 1.8 g / cm 3 and a Beck smoothness of 10 to 80 seconds, the permeability of the activated carbon-containing ink and the deodorant chemical solution becomes more reliable, and the coating operation It is easy to peel off and becomes a sufficiently strong paper tube when it becomes a toilet roll. In forming the long paper tube 30, the other paper tube base paper 31 that is paired with the other paper tube base paper 32 may use a different raw material, for example, changing the basis weight. May be.
　紙管原紙３１に対する糊の付与量は特に限定されないが、１～２５．０ｇ／ｍ2程度である。また、糊は、本発明の効果を妨げない範囲で既知の紙管用のものを用いることができ、アクリル系接着剤、ホットメルト接着剤、澱粉糊、ＰＶＡ（ポリビニルアルコール）等が例示できる。 The amount of glue applied to the paper tube base 31 is not particularly limited, but is about 1 to 25.0 g / m 2 . Moreover, the thing for paper tubes in the range which does not interfere with the effect of this invention can be used for glue, An acrylic adhesive, a hot-melt-adhesive, a starch paste, PVA (polyvinyl alcohol) etc. can be illustrated.
　図示の形態では、各紙管原紙３１，３２のマンドレルシャフト５２への巻き付けは、一対のプーリー５３，５３間に巻き掛けられた平ベルト５４により、マンドレルシャフト５２上の所定部分に位置する筒状部分２９に回転力を与え、その回転により紙管原紙３１，３２をマンドレルシャフト５２の軸心に対して所定角度で引き込んで、螺旋状に巻くようにしている。図示例では、一対のプーリー５３，５３を二機配置して二つの平ベルト５４，５４により、筒状部分２９に回転力を与えているが、一機の一対のプーリーと平ベルトにより筒状部分に回転力を与えるようにしてもよい。また、図示しないが、筒状部分２９に平ベルト５４ではなくロールを当接させて回転力を与えるようにしても、各紙管原紙３１，３２をマンドレルシャフト５２に巻き付けることができる。 In the form shown in the drawing, each of the paper tube base papers 31 and 32 is wound around the mandrel shaft 52 by a flat belt 54 wound between a pair of pulleys 53 and 53 and a cylindrical portion located at a predetermined portion on the mandrel shaft 52. A rotational force is applied to 29, and the paper tube base papers 31 and 32 are drawn at a predetermined angle with respect to the axis of the mandrel shaft 52 by the rotation, and are wound spirally. In the illustrated example, two pairs of pulleys 53, 53 are arranged and rotational force is applied to the tubular portion 29 by two flat belts 54, 54. However, the pair of pulleys 53 and the flat belt form a tubular shape. You may make it give rotational force to a part. Although not shown, the paper tube base papers 31 and 32 can be wound around the mandrel shaft 52 even when a roll is applied to the tubular portion 29 instead of the flat belt 54 to apply a rotational force.
　ここで、紙管原紙３１，３２をマンドレルシャフト５２に巻き付けてスパイラル紙管３０を形成するにあたっては、紙管原紙３１，３２が連続的にマンドレルシャフト５２に送り込まれることにより筒状部分２９が長くなり、その筒状部分２９が連続的に形成されてマンドレルシャフト５２の先端方向に伸びていく。そして、その過程では、筒状部分２９の内面がマンドレルシャフト５２の周面に摺接しながら、マンドレルシャフト５２の先端方向に向かって移動していくことになる。 Here, when the paper tube base papers 31 and 32 are wound around the mandrel shaft 52 to form the spiral paper tube 30, the paper tube base papers 31 and 32 are continuously fed into the mandrel shaft 52 so that the tubular portion 29 becomes long. Thus, the cylindrical portion 29 is continuously formed and extends toward the tip of the mandrel shaft 52. In this process, the inner surface of the cylindrical portion 29 moves toward the distal end of the mandrel shaft 52 while being in sliding contact with the peripheral surface of the mandrel shaft 52.
　本実施形態では、このように長尺の紙管３０を形成する前段又は後段において、紙管原紙のマンドレルシャフト５２にスパイラル巻きした際に長尺の紙管３０の内面側又は外面側となる面を構成する紙管原紙３２に対して印刷機６１等により活性炭含有インキを模様印刷して付与する。図示の形態は、マンドレルシャフトに巻き付ける前の紙管原紙、特に内周面側となる紙管原紙に活性炭含有インキを印刷機で付与して模様を形成している。但し、本実施形態は、この図示の形態に限らず、二枚の紙管原紙の双方に活性炭含有インキのよる印刷付与を行ってもよいし、例えば、１枚又は３枚以上の紙管原紙を用いて、長尺の紙管３０を形成する場合には、紙管原紙の少なくとも一つに付与すればよい。 In the present embodiment, the surface that becomes the inner surface side or the outer surface side of the long paper tube 30 when spirally wound around the mandrel shaft 52 of the paper tube base paper in the preceding stage or the subsequent stage of forming the long paper tube 30 in this way. Activated carbon-containing ink is applied by pattern printing to the paper tube base paper 32 that constitutes the printing paper 61 or the like. In the illustrated form, a pattern is formed by applying activated carbon-containing ink to a paper tube base paper before being wound around a mandrel shaft, in particular, a paper tube base paper on the inner peripheral surface side by a printing machine. However, the present embodiment is not limited to the illustrated form, and printing may be performed using activated carbon-containing ink on both of the two paper tube base papers. For example, one or three or more paper tube base papers may be provided. When a long paper tube 30 is formed using the above, it may be applied to at least one of the paper tube base paper.
　ここで、本実施形態に係る活性炭含有インキは、活性炭と水性顔料とアクリル系樹脂とを含む。さらに、アルコール及び水を含むとより取り扱い性に優れる。好ましい、活性炭含有インキの組成は、活性炭０．０１～１０質量％、水性顔料０．１～５質量％、アクリル系樹脂６５～９５質量％、水４～２０質量％である。この組成の活性炭含有インキであれば、活性炭の定着性に優れ、さらに操業性にも優れる。 Here, the activated carbon-containing ink according to the present embodiment includes activated carbon, an aqueous pigment, and an acrylic resin. Furthermore, when it contains alcohol and water, it is more excellent in handleability. The composition of the activated carbon-containing ink is preferably 0.01 to 10% by mass of activated carbon, 0.1 to 5% by mass of an aqueous pigment, 65 to 95% by mass of an acrylic resin, and 4 to 20% by mass of water. An activated carbon-containing ink having this composition is excellent in the fixability of activated carbon and further in operability.
　活性炭の種類は、ヤシ殻炭、石炭、木炭の破砕品が挙げられる。活性炭は、マイクロトラック法による平均粒子径（体積平均径）が、１～２００μｍであるのが望ましい。また、活性炭含有インキ中における活性炭の含有量は、上記の通り０．０１～１０質量％であるのが望ましく、より好ましくは０．１～５質量％であるのが望ましい。この範囲内であれば、紙管原紙に対してしっかりと定着させることができるとともに、活性炭による消臭効果も十分に発揮させることができる。 </ RTI> Examples of activated carbon include coconut shell charcoal, coal, and charcoal crushed products. The activated carbon preferably has an average particle diameter (volume average diameter) of 1 to 200 μm by the microtrack method. Further, the content of activated carbon in the activated carbon-containing ink is desirably 0.01 to 10% by mass as described above, and more desirably 0.1 to 5% by mass. If it is in this range, it can be firmly fixed to the paper tube base paper, and the deodorizing effect by the activated carbon can be sufficiently exhibited.
　水性顔料は、活性炭含有インキを着色するものである。顔料の成分としてはカーボンブラック、 有機顔料、アニオン性アゾ、フタロシアニン等が挙げられる。活性炭含有インキ中における水性顔料の含有量は、模様の形状・濃さによって調整することができるが、上記の通り０．１～５質量％であるのが望ましい。この範囲であれば、印刷による塗布を行うことができるとともに、活性炭の脱落を助長することもない。 The water-based pigment is for coloring the activated carbon-containing ink. Examples of the pigment component include carbon black, soot organic pigment, anionic azo, phthalocyanine and the like. The content of the aqueous pigment in the activated carbon-containing ink can be adjusted depending on the shape and density of the pattern, but is preferably 0.1 to 5% by mass as described above. If it is this range, while being able to perform application | coating by printing, it does not promote omission of activated carbon.
　アクリル系樹脂は、活性炭及び水性顔料を紙管に定着させる接着剤である。このアクリル系樹脂は、アクリル酸エステル重合体、メタクリル酸エステル重合体が挙げられる。種々の接着剤のなかでも特にアクリル系樹脂は、紙管原紙との馴染みがよく活性炭を紙管原紙にしっかりと定着させることができる。また、アルカリ性のアクリル系樹脂は活性炭との相性がよく、操業性が良好となる。 The acrylic resin is an adhesive that fixes the activated carbon and the aqueous pigment to the paper tube. Examples of this acrylic resin include acrylic acid ester polymers and methacrylic acid ester polymers. Among various adhesives, acrylic resin is particularly familiar with paper tube base paper and can firmly fix activated carbon to paper tube base paper. In addition, the alkaline acrylic resin has good compatibility with activated carbon and good operability.
　アルコールは、活性炭含有インキの紙管原紙への浸透性を高めるとともに乾燥性を早める。活性炭含有インキ中にアルコールを含有させると、紙管原紙への浸透性を高めるとともに乾燥性が早まるため操業性の点で有利となる。アルコールは、低級アルコールが望ましく、エチルアルコール、メチルアルコール、プロパノール類が望ましい。特に、イソプロピルアルコールが望ましい。トイレットロールを構成する紙管原紙３１，３２は、形状維持のため、ある程度の坪量が必要である。紙管原紙３１，３２の坪量は１２０～２２０ｇ／ｍ2と通常のトイレットペーパーやティシュペーパーと比較して高く、ＪＩＳ　Ｐ　８１２２（２００４）に記載の方法で測定したステキヒトサイズ度が１５０～２５０秒であり、アルコールを含まない場合には、乾燥がムラになり乾燥・浸透が遅い。しかし、アルコールを含むことにより、特に活性炭及び水性顔料を定着させるためのアクリル系接着剤等のメジウム分が紙面に素早く浸透するとともに、揮発するため活性炭及び水性顔料の定着が迅速になるとともにしっかりと紙面に定着するようになる。また、後述する消臭剤薬液との併用する場合にアルコールを含むと相乗の有利な効果が発現する。 Alcohol enhances the permeability of the activated carbon-containing ink to the paper tube base paper and accelerates the drying property. Inclusion of alcohol in the activated carbon-containing ink is advantageous in terms of operability because it increases the permeability to the paper tube base paper and accelerates the drying property. The alcohol is preferably a lower alcohol, preferably ethyl alcohol, methyl alcohol, or propanol. In particular, isopropyl alcohol is desirable. The paper tube base papers 31 and 32 constituting the toilet roll need a certain basis weight in order to maintain the shape. The basis weight of the paper tube 31 and 32 is 120 to 220 g / m 2 , which is higher than that of normal toilet paper or tissue paper, and the Steecht size measured by the method described in JIS P 8122 (2004) is 150 to 220 g / m 2. If it does not contain alcohol, the drying becomes uneven and drying / penetration is slow. However, by containing alcohol, medium content such as acrylic adhesive for fixing activated carbon and aqueous pigments penetrates into the paper quickly, and volatilizes, so that the fixing of activated carbon and aqueous pigments is quick and firm. It becomes fixed on paper. Moreover, when it uses together with the deodorizer chemical | medical solution mentioned later, when alcohol is included, the synergistic advantageous effect will express.
　水は、活性炭含有インキのメジウム成分を構成する溶媒であり、活性炭及び水性顔料の分散や粘度調整のために含有される。含有量は、適宜であるが、４～２０質量％であるのが望ましい。 Water is a solvent that constitutes the medium component of the activated carbon-containing ink, and is contained for the purpose of dispersing and adjusting the viscosity of the activated carbon and the aqueous pigment. The content is appropriate but is preferably 4 to 20% by mass.
　上記の活性炭含有インキは、紙管原紙へ定着性に優れ、付着位置を紙管の特に内面としてもトイレットロールとして使用した際にも、ロールホルダーとの摺接によって剥がれ落ちるようなことがない。 The above-mentioned activated carbon-containing ink has excellent fixability to the paper tube base paper, and does not peel off due to sliding contact with the roll holder even when the adhesion position is used as a toilet roll, particularly as the inner surface of the paper tube.
　活性炭含有インキを、紙管原紙を筒状とする前後において付与する方法としては、フレキソ印刷、グラビア印刷、スプレー印刷によって印刷付与するのが望ましい。特に、水性顔料を着色成分とするインキに適するのがフレキソ印刷、スプレー印刷である。フレキソ印刷とする場合のアニロックスロール、刷版ロールの線数は、２０～１００線が適する。グラビア印刷とする場合のアニロックスロール、刷版ロールの線数は、２０～８０線が適する。スプレー印刷とする場合は、ノズル径が０．１～５０ｍｍであるのが適する。これらの印刷条件であれば、活性炭を効果的に紙管原紙の紙面に印刷することができる。 As a method for applying the activated carbon-containing ink before and after making the paper tube base paper into a cylindrical shape, it is desirable to apply printing by flexographic printing, gravure printing, or spray printing. In particular, flexographic printing and spray printing are suitable for inks containing an aqueous pigment as a coloring component. In the case of flexographic printing, the number of lines of anilox roll and printing plate roll is suitably 20 to 100 lines. In the case of gravure printing, 20 to 80 lines are suitable for the number of lines of anilox roll and printing plate roll. In the case of spray printing, the nozzle diameter is suitably 0.1 to 50 mm. Under these printing conditions, the activated carbon can be effectively printed on the paper surface of the paper tube base paper.
　活性炭含有インキの付与量としては、０．１～１５．０ｇ／ｍ2、より好ましくは、０．１～１０．０ｇ／ｍ2である。活性炭含有インキ中における活性炭の含有量は、上記の通り０．０１～１０質量％（０．００００１～１．５ｇ／ｍ2）であるのが望ましく、より好ましくは０．１～５質量％（０．００００１～０．７５ｇ／ｍ2）であるのが望ましい。この範囲であれば、十分な消臭性を発揮することができる。 The applied amount of the activated carbon-containing ink is 0.1 to 15.0 g / m 2 , more preferably 0.1 to 10.0 g / m 2 . As described above, the content of activated carbon in the activated carbon-containing ink is desirably 0.01 to 10% by mass (0.00001 to 1.5 g / m 2 ), more preferably 0.1 to 5% by mass ( 0.00001 to 0.75 g / m 2 ) is desirable. If it is this range, sufficient deodorizing property can be exhibited.
　また、活性炭含有インキを紙面に印刷するにあたっては、ベタ印刷としてもよいが、上記の付与量を考慮すると模様印刷とするのが望ましい。模様印刷とすると意匠性に優れるようにもなる。さらに、模様印刷として、紙管原紙に活性炭含有インキの付与されていない部分を形成すると、特に、後述の消臭剤薬液を付与する場合に、より消臭性の効果において優れるものとなる。 In addition, when printing the activated carbon-containing ink on the paper surface, solid printing may be used, but it is desirable to use pattern printing in consideration of the above-mentioned applied amount. If it is pattern printing, it will be excellent in the design. Furthermore, when a portion to which the activated carbon-containing ink is not applied is formed on the paper tube base paper as pattern printing, particularly when a deodorant chemical solution described later is applied, the deodorizing effect is further improved.
　ここで活性炭含有インキの粘度は、ザーンカップ法における粘度が、５～４０秒であるのが望ましい。なお、本発明におけるザーンカップは、株式会社離合社製ザーンカップのＮｏ．４を用いた値である。この範囲の粘度であれば、印刷性に優れる。特に、上記の活性炭含有インキの組成とした際において、メジウム成分中における活性炭及び水性顔料の分散性が良好で、特にフレキソ印刷、グラビア印刷、スプレー印刷における刷版ロールやアニロックスロールからの回収余剰インキをインキタンクに戻すようにしてもインキ中の活性炭及び水性顔料の偏りがなく、インキを循環しつつ印刷付与を行うことができる。 Here, the viscosity of the activated carbon-containing ink is preferably 5 to 40 seconds as measured by the Zahn cup method. In addition, the Zaan cup in this invention is the No. of Zaan cup made by Kosei Co., Ltd. This is a value using 4. If it is the viscosity of this range, it is excellent in printability. In particular, when the composition of the above-mentioned activated carbon-containing ink is used, the dispersibility of the activated carbon and the aqueous pigment in the medium component is good. In particular, the excess ink recovered from the printing plate roll and anilox roll in flexographic printing, gravure printing, and spray printing. Even if the ink is returned to the ink tank, there is no bias of the activated carbon and the aqueous pigment in the ink, and printing can be applied while circulating the ink.
　他方で、本実施形態は、上記の活性炭含有インキの付与に先立って、ポリフェノール系消臭剤を含む消臭剤薬液を、紙管原紙の少なくとも一方面に塗布するのが望ましい。特に、内周面又は外周面を構成する紙管原紙の一方面に消臭剤薬液を塗工し、その後にその消臭剤薬液塗工面に対して活性炭含有インキを付与するのがよい。特には、紙管原紙を筒状にする前の紙管原紙に対してまず、消臭剤薬液を付与し、乾燥後にその塗布面に活性炭含有インキを模様印刷するなどして、消臭剤薬液塗工部分が、活性炭含有インキによってマスクされていない部分を有するようにし、さらにその後に紙管原紙を筒状に形成するのが望ましい。ただし、この形態に限らず、筒状にする前に消臭剤薬液を紙管原紙に付与し、活性炭含有インキを筒状にした後に付与するようにしてもよい。 On the other hand, in this embodiment, prior to the application of the activated carbon-containing ink, it is desirable to apply a deodorant chemical solution containing a polyphenol deodorant to at least one surface of the paper tube base paper. In particular, it is preferable to apply a deodorant chemical to one side of the paper tube base paper constituting the inner peripheral surface or the outer peripheral surface, and then apply activated carbon-containing ink to the deodorant chemical applied surface. In particular, the deodorant chemical solution is first applied to the paper tube base paper before the paper tube base paper is made into a cylindrical shape, and after the drying, the activated carbon-containing ink is printed on the coated surface. It is desirable that the coated portion has a portion that is not masked by the activated carbon-containing ink, and then the paper tube base paper is formed into a cylindrical shape. However, the present invention is not limited to this configuration, and the deodorant chemical may be applied to the paper tube base paper before forming into a cylindrical shape, and the activated carbon-containing ink may be applied after forming into a cylindrical shape.
　活性炭含有インキと消臭剤薬液とを付与することで、活性炭による悪臭成分の吸着による消臭と、消臭剤薬液中のポリフェノール系消臭剤の化学的消臭とにより、トイレ空間内の多種の悪臭成分を消臭することができ高い消臭効果を発揮する。ここで、ポリフェノール系消臭剤と活性炭含有インキとは、その消臭メカニズムが異なるが、互いの消臭メカニズムを阻害することがない。さらには、そのメカニズムが定かではないものの、極めて優れた消臭効果を発揮するようになる。 By applying the activated carbon-containing ink and the deodorant chemical solution, various types of deodorant in the toilet space can be obtained through deodorization by adsorption of malodorous components by activated carbon and chemical deodorization of the polyphenolic deodorant in the deodorant chemical solution. It can deodorize the bad odor components of this product and exhibits a high deodorizing effect. Here, although the deodorizing mechanism differs between the polyphenol-based deodorant and the activated carbon-containing ink, they do not inhibit each other's deodorizing mechanism. Furthermore, although the mechanism is not clear, an extremely excellent deodorizing effect is exhibited.
　ここで、消臭薬液中には、低級アルコールを含ませるのがよい。さらには、ポリアミド樹脂を含ませるのがよい。本実施形態の消臭剤薬液の好ましい配合割合は、ポリフェノール系消臭剤２５～６７質量％、低級アルコール８～２４質量％である。ポリアミド樹脂を使用するのであれば、ポリアミド樹脂１～１０質量％である。これに適宜の水性溶媒を３～６６質量％含むことができる。水性溶媒は、ポリフェノール系消臭剤、低級アルコール及びポリアミド樹脂と反応性を有さない適宜のものが選択でき、特に水が適する。本実施形態に係るポリフェノール系消臭剤は、ｐＨ４．０～６．９の酸性を呈するものであり、消臭効果を奏する有効成分として茶、柿、ブドウ等の植物及び植物の加工品から抽出されるなどした、ポリフェノール、ポリフェノール誘導体及びポリフェノール類似体の少なくとも一種（以下、ポリフェノール等ともいう）を０．１～４０質量％、好ましくは０．５～２０質量％、特に好ましくは、１～１０質量％含むものである。その他の成分として、水等の溶媒や保存剤、ｐＨ調製剤等の助剤を含みうる。また、安定性、ポリフェノール等への官能基の付与、自身の反応性による消臭効果のさらなる向上の観点等のため有機酸、有機酸塩が配合されていてもよい。有機酸、有機酸塩は、トイレットロールを構成するトイレットペーパーが、人体に直接触れるものであることを考慮して、人体に対する安全性の高いものであるのが望ましく、例えば、乳酸、酒石酸、リンゴ酸、フマル酸、コハク酸、クエン酸、グルタル酸、アミノ酸、アジピン酸、アスコルビン酸、又はこれらの無機塩もしくは有機塩が例示できる。塩を形成する無機塩基としては、ナトリウム、カリウム、リチウム、カルシウム、マグネシウムのようなアルカリ金属又はアルカリ土類金属の水酸化物、酸化物、炭酸塩、炭酸水素塩等が例示できる。また、有機塩基としては、窒素含有塩基、例えば一級、二級又は三級アミン、イミノ基、グアニジノ基、イミダゾリノ基、イミダゾリル基、ピリジル基等の基を有する化合物が例示できる。 Here, the deodorant solution should contain a lower alcohol. Furthermore, it is preferable to include a polyamide resin. The preferred blending ratio of the deodorant chemical solution of the present embodiment is 25 to 67% by mass of the polyphenol deodorant and 8 to 24% by mass of the lower alcohol. If a polyamide resin is used, the amount is 1 to 10% by mass. This can contain 3 to 66% by mass of an appropriate aqueous solvent. As the aqueous solvent, an appropriate one having no reactivity with the polyphenol deodorant, the lower alcohol and the polyamide resin can be selected, and water is particularly suitable. The polyphenol-based deodorant according to this embodiment exhibits an acidity of pH 4.0 to 6.9, and is extracted from plants such as tea, grapes, and grapes, and processed products of plants as active ingredients that exhibit a deodorizing effect. 0.1 to 40% by mass, preferably 0.5 to 20% by mass, particularly preferably 1 to 10% by mass of polyphenol, polyphenol derivative and polyphenol analog (hereinafter also referred to as polyphenol etc.). Including mass%. As other components, an auxiliary agent such as a solvent such as water, a preservative, and a pH adjuster may be included. Moreover, organic acid and organic acid salt may be mix | blended for the viewpoint of the further improvement of the deodorizing effect by stability, the provision of the functional group to polyphenol, etc., own reactivity. It is desirable that the organic acid and the organic acid salt are highly safe for the human body, considering that the toilet paper constituting the toilet roll is in direct contact with the human body. For example, lactic acid, tartaric acid, apple Examples thereof include acids, fumaric acid, succinic acid, citric acid, glutaric acid, amino acids, adipic acid, ascorbic acid, and inorganic or organic salts thereof. Examples of inorganic bases that form salts include alkali metal or alkaline earth metal hydroxides, oxides, carbonates, bicarbonates such as sodium, potassium, lithium, calcium, and magnesium. Examples of the organic base include nitrogen-containing bases such as compounds having groups such as primary, secondary or tertiary amines, imino groups, guanidino groups, imidazolino groups, imidazolyl groups and pyridyl groups.
　上記ポリフェノール系消臭剤は、主に有効成分であるポリフェノール等のフェノール性水酸基の反応等により、トイレ空間内の悪臭成分の一つであるアンモニアに対する高い消臭機能を有する。もちろん、アンモニアに加えて、硫化水素、メチルメルカプタン、トリメチルアミンに対して反応性を有して消臭機能を有するものも存在し、用いるポリフェノール系消臭剤はそのようなものであってもよい。例えば、ポリフェノール誘導体の中には、特許３９１９７２９号のように人為的に分子量の高いポリフェノールに対して適宜の官能基を持たせて、特定の成分に対する消臭機能を付加或いは高めたものが知られているが、そのようなものであってもよい。 The above-mentioned polyphenol-based deodorant has a high deodorizing function against ammonia, which is one of the malodorous components in the toilet space, mainly due to the reaction of phenolic hydroxyl groups such as polyphenol, which is an active ingredient. Of course, in addition to ammonia, there are those having reactivity to hydrogen sulfide, methyl mercaptan, and trimethylamine and having a deodorizing function, and such polyphenol deodorants may be used. For example, among polyphenol derivatives, there are known compounds such as Japanese Patent No. 3919729 in which an appropriate functional group is added to an artificially high molecular weight polyphenol to add or enhance a deodorizing function for a specific component. However, it may be such.
　本実施形態に係るポリフェノール等のより好ましい具体例としては、タンニン、カテキン、ルチン、アントシアニン、エラグ酸、クマリン、フラボン及びこれらの誘導体又は前駆体である。これらはトイレの悪臭成分に対して特に高い消臭効果を発揮する。したがって、ポリフェノール系消臭剤は、これらを少なくとも一種含むものが望ましい。 More preferred specific examples of the polyphenol and the like according to this embodiment are tannin, catechin, rutin, anthocyanin, ellagic acid, coumarin, flavone, and derivatives or precursors thereof. These exert a particularly high deodorizing effect on the odor component of the toilet. Therefore, it is desirable that the polyphenol deodorant contains at least one of these.
　上記具体例のなかでも、特に好ましいものは、タンニン及びその誘導体である。タンニン及びタンニン誘導体は、分子量が大きくフェノール性水酸基を多く有するため消臭機能に優れる。なお、タンニンは、縮合型タンニン、加水分解型タンニンのいずれでよい。また、タンニンのなかでも、柿由来の柿タンニンは、分子量が非常に大きく、消臭効果に極めて優れるため、ポリフェノール系消臭剤としては、この柿タンニン及び柿タンニン誘導体の少なくとも一方を含むようにするのがよい。 Of the above specific examples, tannin and its derivatives are particularly preferable. Tannins and tannin derivatives have a high deodorizing function because of their large molecular weight and many phenolic hydroxyl groups. Tannin may be either condensed tannin or hydrolyzed tannin. Among the tannins, cocoon tannin derived from cocoon has a very large molecular weight and is extremely excellent in the deodorizing effect. Therefore, the polyphenol deodorant should contain at least one of this tannin and cocoon tannin derivatives. It is good to do.
　また、ポリフェノール系消臭剤は、市販されているものを用いることができる。例えば、リリース科学工業株式会社製のPancil COS-15、Pancil COS-17、Pancil CL-10、Pancil AS-10、Pancil AS-20、Pancil　BA-210-1、Pancil COS-5、Pancil FG-22、Pancil FG-25、Pancil FG-30、Pancil FG-60、Pancil FG-70、Pancil FG-99、Pancil FX10、Pancil PO -10、Pancil BA-200E-1、株式会社日新化学研究所製のビームスターOFを適宜用いることができる。 In addition, commercially available polyphenol deodorants can be used. For example, Pancil COS-15, Pancil COS-17, Pancil CL-10, Pancil AS-10, Pancil AS-20, Pancil BA-210-1, Pancil COS-5, Pancil FG-22 manufactured by Release Science , Pancil FG-25, Pancil FG-30, Pancil FG-60, Pancil FG-70, Pancil FG-99, Pancil FX10, Pancil PO-10, Pancil BA-200E-1, manufactured by Nissin Chemical Laboratory Beam star OF can be used as appropriate.
　他方、本実施形態における低級アルコールとしては、エチルアルコール、メチルアルコール、プロパノール類が挙げられる。これらの混合アルコールでもよい。上記のとおり、トイレットロールを構成する紙管原紙３１，３２は、ＪＩＳ　Ｐ　８１２２（２００４）に記載の方法で測定したステキヒトサイズ度が１５０～２５０秒であり、アルコールを含まない場合には、乾燥がムラになり乾燥・浸透が遅い。また、ポリフェノール系消臭剤は、紙へのなじみが良好ではない。したがって、そのまま塗工しても弾いたりしてムラになりやすい。しかし、ポリフェノール系消臭剤とともに低級アルコールを含有させると、ポリフェノール系消臭剤の紙管原紙へのなじみ及び乾燥性が向上し、紙管原紙にムラなく効果的に付与できるようになる。また、ポリフェノール系消臭剤は、植物由来の多糖類を排除することが難しく、これに起因するべたつきが発生しやすいが、低級アルコールを含有させることにより、べたつきが防止される。 On the other hand, examples of the lower alcohol in the present embodiment include ethyl alcohol, methyl alcohol, and propanols. These mixed alcohols may be used. As described above, the paper tube base papers 31 and 32 constituting the toilet roll have a Steecht size measured by the method described in JIS P 8122 (2004) of 150 to 250 seconds and do not include alcohol. Drying becomes uneven and drying / penetration is slow. Moreover, the polyphenol-type deodorant is not well adapted to paper. Therefore, even if it is applied as it is, it tends to play and become uneven. However, when a lower alcohol is contained together with the polyphenol-based deodorant, the familiarity and drying properties of the polyphenol-based deodorant to the paper tube base paper are improved, and the paper tube base paper can be effectively imparted with no unevenness. Polyphenol-based deodorants are difficult to exclude plant-derived polysaccharides, and stickiness due to this is likely to occur, but stickiness is prevented by containing a lower alcohol.
　ここで、上述のとおり活性炭含有インキにおいてもアルコールを含有させることが望ましい。消臭剤薬液を用いる場合には、消臭剤薬液中に低級アルコールを含ませるのが特に望ましいため、前段で消臭剤薬液を付与し、さらにその後に活性炭含有インキを付与する場合にその活性炭含有インキ中にアルコールが含有されていると、紙管原紙への活性炭含有インキの馴染みがより良好であり、印刷性及び定着性においてより高い効果が発揮される。特に、このように活性炭含有インキにおいてもアルコールを含有させる場合には、紙管原紙を巻き取った原反ロールから紙管原紙を繰り出して、マンドレルシャフトに供給するまでの間において、ポリフェノール系消臭剤と活性炭含有インキとをオンラインで付与するのが望ましい。 Here, as described above, it is desirable that the activated carbon-containing ink also contains alcohol. When using a deodorant chemical solution, it is particularly desirable to include a lower alcohol in the deodorant chemical solution. Therefore, when the deodorant chemical solution is applied in the previous stage and then the activated carbon-containing ink is applied, the activated carbon When alcohol is contained in the contained ink, the familiarity of the activated carbon-containing ink to the paper tube base paper is better, and a higher effect is exhibited in printability and fixability. In particular, when alcohol is also contained in the activated carbon-containing ink as described above, the polyphenol-based deodorizing process is performed until the paper tube base paper is unwound from the raw roll obtained by winding the paper tube base paper and supplied to the mandrel shaft. It is desirable to apply the agent and the activated carbon-containing ink online.
　また、上述のとおり活性炭とポリフェノール系消臭剤をともに紙管に付与すると優れた消臭効果を発揮する。しかし、活性炭の紙管原紙への定着に高い効果を奏するアクリル樹脂は、カルボキシル基を有しているため、このカルボキシル基がポリフェノールの水酸基と反応し、凝集が生じて塗布ムラを生じてしまう。したがって、ポリフェノール系消臭剤と活性炭を紙管に付与する場合には、両者を別途にかつ確実に紙管原紙に定着させる必要がある。このため、両者を併用する場合には、まず、ポリフェノール系消臭剤を紙管原紙に付与し、その後に活性炭含有インキを付与するようにする。なお、活性炭含有インキ付与後にポリフェノール系消臭剤を付与すると、オンライン塗布の場合にはインキが乾燥しきらないうちに消臭剤塗工工程に移行してしまう可能性があり、また、インキが乾燥した状態となっていても付与部分に液体である消臭剤を付与することになるため、活性炭含有インキが製造時又は製品時において脱落しやすくなるおそれがある。 Also, as described above, when both activated carbon and polyphenol deodorant are applied to the paper tube, an excellent deodorizing effect is exhibited. However, the acrylic resin that has a high effect on fixing the activated carbon to the paper tube base paper has a carboxyl group, and this carboxyl group reacts with the hydroxyl group of the polyphenol to cause aggregation and uneven coating. Therefore, when applying a polyphenol-type deodorant and activated carbon to a paper tube, it is necessary to fix both to a paper tube base paper separately and reliably. For this reason, when both are used together, first, a polyphenol-type deodorant is applied to the paper tube base paper, and then the activated carbon-containing ink is applied. If a polyphenol-based deodorant is applied after application of the activated carbon-containing ink, in the case of online application, the ink may be transferred to the deodorant coating process before the ink is completely dried. Even if it is in a dry state, a deodorant that is a liquid is applied to the application portion, so that the activated carbon-containing ink may easily fall off during production or product.
　また、本実施形態では、消臭剤薬液中にポリアミド樹脂を用いると、ポリフェノール系消臭剤と反応することなくバインダーとして機能させることができる。これによりポリフェノール系消臭剤を紙管原紙３２にムラ無く定着させることが可能となる。また、ポリアミド樹脂は、紙管原紙３２への付与後に乾燥して比較的強固な塗膜を形成するためマンドレルシャフトとの摺接時など紙管の加工時やトイレットロールの実使用時における消臭剤の剥離防止性も高まる。なお、消臭剤薬液中におけるポリアミド樹脂としては、水溶液中においてアミド基を有するものであり、具体例としてはポリアクリルアミド樹脂が挙げられる。商品としては、例えば、東洋インキ株式会社製アクワＮＡＤＥが使用できる。一般に、染料及び顔料を用いた水性インキ中のバインダー樹脂としてもちいられる。 In this embodiment, when a polyamide resin is used in the deodorant chemical, it can function as a binder without reacting with the polyphenol deodorant. As a result, it becomes possible to fix the polyphenol deodorant to the paper tube base paper 32 evenly. Further, since the polyamide resin is dried after being applied to the paper tube base paper 32 to form a relatively strong coating film, the deodorizing is performed at the time of processing the paper tube such as when sliding on the mandrel shaft or when the toilet roll is actually used. The anti-peeling property of the agent is also increased. In addition, as a polyamide resin in a deodorant chemical | medical solution, it has an amide group in aqueous solution, A polyacrylamide resin is mentioned as a specific example. As a product, for example, AQUA NADE manufactured by Toyo Ink Co., Ltd. can be used. Generally, it is used as a binder resin in water-based inks using dyes and pigments.
　他方で、紙管原紙に消臭剤薬液を付与するには、図示の形態では、予め消臭剤薬液が付与された紙管原紙を巻かれた原反ロール３２Ａを用い、そこから当該紙管原紙３２を繰出すようにしている。ただし、上述のようにマンドレルシャフト５２への巻き付けを行なう前の特に活性炭含有インキ付与前、塗工機等で紙管原紙の一方面の全体又は一部に塗工して行なってもよい。但し、この形態に限らず、原反ロールに巻き取る前の紙管原紙３２，３１に対して予め消臭剤薬液４１を塗工しておいてもよい。本実施形態では、ポリフェノール系消臭剤を付与してもべたつき等がないため、原反ロール巻き取り前に消臭剤薬液を付与しておいても原反ロールからスムーズに紙管原紙を繰出すことができる。 On the other hand, in order to apply the deodorant chemical solution to the paper tube base paper, in the illustrated form, the raw paper roll 32A around which the paper tube base paper preliminarily applied with the deodorant chemical solution is used is used, and from there the paper tube The base paper 32 is fed out. However, as described above, the coating may be performed on the whole or a part of one side of the paper tube base paper with a coating machine or the like, particularly before application of the activated carbon-containing ink, before winding around the mandrel shaft 52. However, the present invention is not limited to this, and the deodorant chemical solution 41 may be applied in advance to the paper tube base paper 32 and 31 before being wound on the raw roll. In this embodiment, even if a polyphenol-based deodorant is applied, there is no stickiness or the like. Therefore, even if a deodorizer chemical is applied before winding the raw roll, the paper tube base paper is smoothly fed from the original roll. Can be put out.
　紙管原紙３２に消臭剤薬液層を付与する塗工機としては、フレキソ印刷機、グラビア印刷機等の既知の印刷機のなかから適宜選択することができる。塗工機による消臭剤薬液の付与態様としては、ベタ印刷のほか網点状、円状、ブロック状など適宜のパターン印刷、図形などの模様印刷や文字の印刷として付与することができる。 The coating machine for applying the deodorant chemical liquid layer to the paper tube base paper 32 can be appropriately selected from known printing machines such as flexographic printing machines and gravure printing machines. As an application mode of the deodorant chemical solution by the coating machine, it can be applied as solid printing, appropriate pattern printing such as halftone dots, circles, and blocks, pattern printing such as graphics, and character printing.
　消臭剤薬液の付与量としては、印刷による模様等に応じて適宜設計できるが、付与量が５～８０ｇ／ｍ2となるようにするのが望ましい。この範囲であれば、生産性よく消臭剤薬液４１を十分に塗工することができ、また、十分な消臭効果を奏する量の消臭剤を付与することができる。 The application amount of the deodorant chemical solution can be appropriately designed according to the pattern or the like by printing, but it is desirable that the application amount is 5 to 80 g / m 2 . If it is this range, the deodorizer chemical | medical solution 41 can fully be coated with sufficient productivity, and the deodorizer of the quantity which has a sufficient deodorizing effect can be provided.
　他方、図示の形態では、紙管原紙に消臭剤薬液を付与した後にヒーター（乾燥機）６２により付与部分の乾燥を行なうようにしている。このように乾燥を行なうことにより塗膜が確実に形成されやすくなり、後段の加工が行ないやすくなる。 On the other hand, in the form shown in the figure, the application portion is dried by the heater (dryer) 62 after the deodorant chemical solution is applied to the paper tube base paper. By drying in this manner, a coating film is easily formed with certainty, and subsequent processing is facilitated.
〔ログ製造工程（Ｂ）〕
　他方、本実施形態では、上記の長尺の紙管３０の製造と平行して又はその後において、ログ製造工程（図１中（Ｂ））にて、ログ７０を製造する。なお、ログ７０とは、業界においての一般用語であり、最終製品であるトイレットロール１０の径と同径でありかつ幅が最終製品の複数個分ある中間製品である。 [Log production process (B)]
On the other hand, in this embodiment, the log 70 is manufactured in the log manufacturing process ((B) in FIG. 1) in parallel with or after the manufacturing of the long paper tube 30 described above. The log 70 is a general term in the industry, and is an intermediate product having the same diameter as that of the toilet roll 10 as a final product and having a width corresponding to a plurality of final products.
　このログ７０の製造は、連続的に又は段階的に、長尺の紙管３０と実質的に同幅のトイレットペーパー原紙７１，７１を、ロール７１Ａ，７１Ａから繰り出すとともに巻き付けてログ７０を形成する。この巻き付けは、既知のワインダー装置Ｘ２が利用できる。 In manufacturing the log 70, the log 70 is formed by unwinding and winding the toilet paper base sheets 71 and 71 having substantially the same width as the long paper tube 30 from the rolls 71A and 71A continuously or stepwise. . A known winder device X2 can be used for this winding.
　図示の形態では、二つのロール７１Ａ，７１Ａから単層のトイレットペーパー原紙７１，７１を繰り出して、重ね合わせ部８１にて２プライのトイレットペーパー原紙７２とした後、ミシン目線形成装置８２にてミシン目線の形成を行なった後、巻き取り装置８３にて巻き取り２プライ構造となるようにしている。但し、本発明に係るトイレットペーパー原紙は、２プライに限定されず、１プライ若しくは３プライ以上であってもよい。また、複数プライ構造とする場合には、各原紙の坪量や物性等は同じである必要もない。さらに、ワインダー装置Ｘ２でプライ構造にするのではなく、予め積層されたトイレットペーパー原紙を巻き取ったロールからトイレットペーパー原紙を繰出して長尺の紙管３０に巻き付けてログ７０を形成すようにしてもよい。 In the form shown in the figure, single- layer toilet paper 71, 71 is fed from two rolls 71A, 71A to form a 2-ply toilet paper 72 in the overlapping portion 81, and then the perforated line forming device 82 After the line of sight is formed, a winding device 83 is used to form a winding two-ply structure. However, the toilet paper base paper according to the present invention is not limited to 2 plies, and may be 1 ply or 3 plies or more. In the case of a multi-ply structure, the basis weight, physical properties, etc. of each base paper need not be the same. Further, instead of using the ply structure in the winder device X2, the log 70 is formed by feeding the toilet paper base from a roll obtained by winding a pre-laminated toilet paper base and winding it around the long paper tube 30. Also good.
　また、図示の形態では、ミシン目線形成装置８２を設けてミシン目線を付与する形態を示しているが、本発明では必ずしもミシン目線形成装置及びミシン目線の付与は必須ではない。さらに、本実施形態において、図示はしないが、ミシン目線付与装置８２の前段に既知のコンタクトエンボス付与装置を設けてコンタクトエンボスを付与してもよいし、重ね合わせ部８１の前段で各トイレットペーパー７１，７１にエンボスロールでエンボスを付与するようにしてもよいし、その付与したエンボスの凸部頭頂に接着剤を付与して係る接着剤でシート同士を積層一体化するようにしてもよい。 In the illustrated embodiment, the perforated line forming device 82 is provided to give the perforated line. However, in the present invention, the perforated line forming device and the perforated line are not necessarily provided. Further, in the present embodiment, although not shown, a known contact embossing device may be provided in front of the perforation line applying device 82 to provide contact embossing, or each toilet paper 71 may be provided in front of the overlapping portion 81. , 71 may be embossed with an embossing roll, or an adhesive may be applied to the top of the convex portion of the embossed surface, and the sheets may be laminated and integrated with the adhesive.
〔裁断工程（Ｃ）〕
　以上のように、ログ７０を製造したならば、このログ７０を既知のログアキュームレーターＸ３で複数本をストックしつつ後段のログカッター設備Ｘ４へと移動させる。そして、その後に図１中（Ｃ）に示すように、既知のログカッター９１でログ７０を製品幅に裁断し、個々のトイレットロール１０，１０…とする。 [Cutting process (C)]
As described above, when the log 70 is manufactured, the log 70 is moved to the subsequent log cutter facility X4 while stocking a plurality of logs by the known log accumulator X3. And after that, as shown to (C) in FIG. 1, the log 70 is cut | judged to a product width with the known log cutter 91, and it is set as each toilet roll 10,10 ....
「トイレットロールの製造方法の他の実施形態」
　上記説明の実施形態は、ログ７０を仲介してトイレットロール１０を形成する方法を説明したが、本発明はログ７０を形成しないでトイレットロール１０を形成することもできる。 “Other Embodiments of Toilet Roll Manufacturing Method”
In the above-described embodiment, the method of forming the toilet roll 10 through the log 70 has been described. However, the present invention can form the toilet roll 10 without forming the log 70.
　例えば、上述の長尺の紙管３０を形成する工程Ａにおいて、筒状部分２９をトイレットロール１０と同幅かやや幅広でカッター５８によりカットして紙管を形成した後、これと同幅のトイレットペーパー原紙７２を巻き付けることで、ログ７０を介さずに直接的にトイレットロール１０とすることができる。トイレットロール１０よりやや幅広の紙管にトイレットロール１０よりやや幅広のトイレットペーパー原紙７２を巻き付けて、その両端面部分をカットすることで端面を整えることができる。消臭剤薬液４１やその付与形態については、上記ログ７０を仲介する方法と同様に行なうことができる。 For example, in the process A for forming the long paper tube 30 described above, the tubular portion 29 is cut with the cutter 58 with the same width or slightly wider as the toilet roll 10 to form a paper tube, and then the same width as this. By wrapping the toilet paper base paper 72, the toilet roll 10 can be formed directly without using the log 70. An end surface can be prepared by winding a toilet paper base 72 slightly wider than the toilet roll 10 around a paper tube slightly wider than the toilet roll 10 and cutting both end portions. About the deodorant chemical | medical solution 41 and its provision form, it can carry out similarly to the method of mediating the said log 70. FIG.
「トイレットロール」
　次いで、本実施形態に係るトイレットロール１０について説明する。本実施形態に係るトイレットロール１０は、図３に示すとおり、紙管１１に帯状の家庭用薄葉紙であるトイレットペーパー１２が巻かれたものである。このトイレットロール１０は、上記のトイレットロール１０の製造方法により製造することができる。 "Toilet roll"
Next, the toilet roll 10 according to the present embodiment will be described. As shown in FIG. 3, the toilet roll 10 according to the present embodiment is obtained by winding a toilet paper 12 that is a strip-shaped household thin paper around a paper tube 11. This toilet roll 10 can be manufactured by the method for manufacturing the toilet roll 10 described above.
　本実施形態にかかるトイレットロール１０の大きさ等は、幅Ｌ１が１００～１１５ｍｍ、直径Ｌ２が１００～１２０ｍｍ、巻き長さ（トイレットペーパーの全長）が１８～１２０ｍ、紙管内径Ｌ３が３５～５０ｍｍであるのが望ましい。この大きさであれば一般的なトイレットロール用のペーパーホルダーが利用でき、トイレットペーパーの長さも十分である。 The size and the like of the toilet roll 10 according to the present embodiment includes a width L1 of 100 to 115 mm, a diameter L2 of 100 to 120 mm, a winding length (total length of toilet paper) of 18 to 120 m, and a paper tube inner diameter L3 of 35 to 50 mm. It is desirable that With this size, a general toilet roll paper holder can be used, and the length of the toilet paper is sufficient.

　本発明の消臭効果、特に活性炭とポリフェノール系消臭剤との併用に関しての試験を行い、表１に示した。試験に用いた紙管原紙は、坪量１７０ｇ／ｍ2、紙厚２００μｍ、ステキヒトサイズ度２００秒である。紙管の大きさは、直径４１ｍｍ×長さ１１４ｍｍである。 Table 1 shows the deodorizing effect of the present invention, in particular, a test relating to the combined use of activated carbon and a polyphenol-based deodorant. The paper tube base paper used for the test has a basis weight of 170 g / m 2 , a paper thickness of 200 μm, and a Steecht size of 200 seconds. The size of the paper tube is 41 mm in diameter × 114 mm in length.
　まず、上記の紙管原紙で作成した紙管に対して、ポリフェノール系消臭剤を含む消臭剤薬液を一方面に全面付与し、その付与面に活性炭含有量の異なる活性炭含有インキを付与した試料（実施例１～５）と、一方面にポリフェノール系消臭剤を付与せず活性炭含有インキのみを付与した試料（実施例６）と、ポリフェノール系消臭剤のみを一方面に全面付与した試料（比較例）とを作成し、各試料の消臭性を試験した。試験は、アンモニアとメチルメルカプタンに対する消臭効果を確認した。 First, to the paper tube made of the above paper tube base paper, a deodorant chemical solution containing a polyphenol-based deodorant was applied to one surface, and activated carbon-containing inks having different activated carbon contents were applied to the application surface. A sample (Examples 1 to 5), a sample (Example 6) in which only the activated carbon-containing ink was applied on one side without applying a polyphenol-based deodorant, and only a polyphenol-based deodorant was applied on one side. Samples (comparative examples) were prepared, and the deodorizing properties of each sample were tested. The test confirmed the deodorizing effect on ammonia and methyl mercaptan.
　用いた消臭剤薬液は、リリース科学工業株式会社製Pancil FG-25と株式会社日新化学研究所製ビームスターＯＦとを含むものである。活性炭含有インキは、ＬＯＸＳメジウム（水６７～６９質量％、アクリル系樹脂３０質量％、浸透剤（イソプロピルアルコール）１～３質量％）と、水性顔料（東洋インキ株式会社製　ＬＯＸ９２スミ　カーボンブラック）と、活性炭（株式会社日新化学研究所製）とを含むものである。 The deodorant chemical used includes Pancil® FG-25 manufactured by Release Science Industrial Co., Ltd. and Beam Star OF manufactured by Nissin Chemical Laboratory. The activated carbon-containing ink is composed of LOXS medium (67 to 69% by weight of water, 30% by weight of acrylic resin, 1 to 3% by weight of penetrant (isopropyl alcohol)), and an aqueous pigment (LOX92 Sumi carbon black manufactured by Toyo Ink Co., Ltd.). And activated carbon (manufactured by Nissin Chemical Laboratory Co., Ltd.).
　消臭効果の確認試験は、より具体的には、容量１０Ｌの密閉容器に尿臭を模擬したアンモニアを３２０ｐｐｍ、メチルメルカプタン１４ｐｐｍの濃度で発生させ、その容器内に、消臭剤を付与した各実施例及び比較例に係る紙管を、それぞれ１本投入し、１時間後にアンモニア及びメチルメルカプタンの濃度を検知管法にて測定することで行った。 More specifically, in the deodorization effect confirmation test, ammonia simulating urine odor was generated in a sealed container having a capacity of 10 L at a concentration of 320 ppm and methyl mercaptan of 14 ppm, and a deodorant was added to the container. One paper tube according to each of the examples and the comparative examples was added, and after 1 hour, the concentrations of ammonia and methyl mercaptan were measured by the detection tube method.
　濃度検知には、ガステック株式会社製の検知器（ＧＶ－１００Ｓ）および検知管（３Ｌおよび３Ｌａ）を用いた。結果は、表１のとおりである。なお、消臭効果は、アンモニア及びメチルメルカプタンの減少率（消臭率）を次の基準で評価した。 For concentration detection, a detector (GV-100S) and a detector tube (3L and 3La) manufactured by Gastec Corporation were used. The results are shown in Table 1. In addition, the deodorizing effect evaluated the decreasing rate (deodorizing rate) of ammonia and methyl mercaptan on the following reference | standard.
　アンモニアの消臭率が９５％以上かつメチルメルカプタンの消臭率が７０％以上のものを「◎」、アンモニアの消臭率が８５％以上かつメチルメルカプタンの消臭率が５０％以上のものを「○」、アンモニアの消臭率が８５％未満またはメチルメルカプタンの消臭率が５０％未満のものを「×」とした。 Ammonia deodorization rate is 95% or more and methyl mercaptan deodorization rate is 70% or more “◎”, ammonia deodorization rate is 85% or more and methyl mercaptan deodorization rate is 50% or more “O” indicates that the deodorization rate of ammonia is less than 85% or the deodorization rate of methyl mercaptan is less than 50%.
　表１に示されるとおり、活性炭含有インキを付与した実施例１～６は、ポリフェノール系消臭剤のみの比較例と比較して、メチルメルカプタンの消臭効果に優れる。さらに、両者を併用したものは、アンモニア及びメチルメルカプタン双方の消臭効果が、活性炭含有インキのみのものとポリフェノール系消臭剤のみのものとを比較して、各々単独の効果以上の相乗の効果が確認できる。本結果から、活性炭含有インキの優れた消臭効果と、ポリフェノール系消臭剤との併用によって相乗の効果を奏することが確認された。また、特に、活性炭含有インキ中における活性炭の含有量が、２．５質量％を超えると、メチルメルカプタンの消臭効果が顕著に高まることが確認された。 As shown in Table 1, Examples 1 to 6 to which the activated carbon-containing ink was applied are superior in the deodorizing effect of methyl mercaptan compared to the comparative example using only the polyphenol deodorant. In addition, the combination of both, the deodorizing effect of both ammonia and methyl mercaptan, compared to the activated carbon-containing ink alone and the polyphenol-based deodorant alone, synergistic effect more than each single effect Can be confirmed. From this result, it was confirmed that there was a synergistic effect by combining the excellent deodorizing effect of the activated carbon-containing ink and the polyphenol-based deodorant. In particular, it was confirmed that when the content of activated carbon in the activated carbon-containing ink exceeds 2.5% by mass, the deodorizing effect of methyl mercaptan is remarkably increased.
