Description
本発明は、ティシュペーパー及びティシュペーパー製品に関するものである。
The present invention relates to tissue paper and tissue paper products.
国内市場のティシュペーパーは大きく分けて、非保湿ティシューと保湿ティシューに大別される。ここで、保湿ティシューは抄紙されたティシュー原紙にグリセリン等の保湿剤を塗布して生産されたティシューであり、非保湿ティシューとはティシュー原紙に保湿剤を塗布しない一般的なティシューである。
ティシュペーパーの用途は、鼻かみ用途を含むフェイシャル用を中心とした主に対人用途であり、保湿ティシューは鼻かみ用に特化された製品仕様とされている。
従来、ティシュペーパーは鼻かみ用途を中心としたフェイシャル用途で使用されてきたことから、肌触りの良さを追求するため、これまで数多くの試みがなされ、品質改良を重ねてきた。例えば、各種の柔軟剤を原料に添加し製品の柔軟性を向上させる、繊維粗度の低いしなやかな繊維を多く使用する、湿紙のドライヤー乾燥時の貼りつきとドクター当りの調整により細かなクレーピングを形成する、カレンダーにより表面性を向上させる、原料噴射速度と網部の速度の比率調整により横強度を維持しつつ原料の叩解度を低く調整する、等の技術により、紙の柔らかさや滑らかさの改善が図られてきた。 The tissue paper in the domestic market is broadly divided into non-moisturizing tissue and moisturizing tissue. Here, the moisturizing tissue is a tissue produced by applying a moisturizing agent such as glycerin to a tissue base paper that has been made, and the non-humidifying tissue is a general tissue that does not apply a moisturizing agent to the tissue base paper.
The use of tissue paper is mainly for personal use, mainly for facial use including nasal cover, and moisturizing tissue is considered to be a product specification specialized for nasal blow.
Traditionally, tissue paper has been used for facial applications, mainly for nasal clasps, and so many attempts have been made in the past to improve the touch and quality improvements have been repeated. For example, various softeners are added to the raw materials to improve the flexibility of the product. Many supple fibers with low fiber roughness are used. Fine creping by sticking when wet paper dryer is dried and adjusting per doctor. The softness and smoothness of the paper is achieved by technologies such as forming the surface, improving the surface properties by a calender, and adjusting the raw material beating rate to a low level while maintaining the lateral strength by adjusting the ratio of the web speed. Improvements have been made.

Improvements have been made.
しかし更なる品質向上のためには、非保湿ティシューでは技術的な限界があることや、花粉症やアレルギー性鼻炎の罹患者の増加等が要因となり、保湿ティシューが開発され現在ティシュー市場の一部を占めている。
アレルギー性鼻炎や花粉症などのヘビーユーザーは日に数十回以上も鼻をかむことにより、鼻およびその周辺がティシューとの摩擦により、軽い炎症を起こし赤くなりヒリヒリとした傷みを感じやすい。そのため、このようなユーザーには、ティシュー表面の摩擦の小さなもの、つまり滑らかさを有する物が好ましく使用される。保湿ティシューはグリセリン等の吸湿性のある保湿剤を含む水系ローション薬液を、衛生薄葉紙の基紙に対し塗布する。グリセリンは化粧品に使われているように肌への刺激性が少なく、吸湿してティシューをしっとり、柔らかくするとともにティシューの表面に薄い皮膜を形成し、一般の非塗布ティシューに比して明らかに柔らかで、滑らかな肌触りを有する差別化した商品として認知されている。例えば、油性物質と保湿剤を外添塗布する技術が紹介されている(特許文献1)。 However, in order to further improve quality, non-moisturizing tissue has technical limitations and an increase in the number of people suffering from hay fever and allergic rhinitis has led to the development of moisturizing tissue that is now part of the tissue market. Accounted for.
Heavy users, such as allergic rhinitis and hay fever, bite their nose more than tens of times a day, and the nose and its surroundings are rubbed against tissue, causing mild inflammation and redness. Therefore, for such a user, a material having a small friction on the tissue surface, that is, a material having smoothness is preferably used. The moisturizing tissue applies an aqueous lotion solution containing a hygroscopic moisturizing agent such as glycerin to the base paper of the sanitary thin paper. Glycerin is less irritating to the skin as used in cosmetics, absorbs moisture and moistens and softens the tissue, forms a thin film on the surface of the tissue, and is clearly softer than ordinary non-applied tissue It is recognized as a differentiated product with a smooth touch. For example, a technique for externally applying an oily substance and a humectant has been introduced (Patent Document 1).

このように保湿ティシューは認知され消費量は増加しているが、保湿ティシューのヘビーユーザーの中には、鼻をかんだ後に肌に保湿剤が残り、ベタつき感を感じ、これを嫌うユーザーが一部に存在する。このベタつき感については特許文献2のように、有機、無機粉体を配合するなど薬剤組成を変更することで、ベタつき感を改善する方法も知られている。
In this way, moisturizing tissue is recognized and consumption is increasing, but some moisturizing tissue heavy users leave moisturizers on their skin after biting their nose and feel sticky, and some dislike this Exists. Regarding this sticky feeling, a method for improving the sticky feeling by changing the chemical composition such as blending organic and inorganic powders as in Patent Document 2 is also known.
従来、保湿ティシューの製造は、抄紙工程、プライ工程の後、オフマシンで薬液塗布を行い、次いでロータリー式インターフォルダによる折り加工を行うのが一般的であり、非保湿ティシューの製造に多用されるマルチスタンド式インターフォルダによる製造は行なわれていない。
Conventionally, in the manufacture of moisturizing tissue, it is common to apply chemicals off-machine after the paper making process and the plying process, and then perform folding using a rotary interfolder, which is often used for manufacturing non-humidifying tissue. No multi-stand interfolder is manufactured.
ボックスティシュー製品としては、箱の製造コストや輸送コストの削減の観点より、高さを減じ、コンパクト化した収納箱(高さ50~65mm程度)を使用するのが主流となっている。コンパクト化した収納箱を使用する場合、通常、内部に収納されるティシュペーパーは圧縮されており、圧縮に伴う最上層のティシュペーパーの取り出しにくさを解消するため、収納箱上面の取り出し口は箱上面の長辺方向に対して長めに設計されている(特許文献3)。しかし、保湿ティシューにおいては、その滑り性の高さから、ティシュペーパーが取り出し口に保持されにくく、収納箱内に落ち込み、ポップアップしづらくなる、という問題が生じ得る。一方で、ティシュペーパーを取り出し口に保持するために、取り出し口を小さくする、取り出し口に配されるフィルムの剛性を高める等の措置を講じた場合、ティシュペーパーの取り出し時に破れやすい、という問題が生じ得る。
For box tissue products, it is the mainstream to use compact storage boxes (height of about 50 to 65 mm) with reduced height from the viewpoint of reducing box manufacturing costs and transportation costs. When using a compact storage box, the tissue paper stored inside is usually compressed, and the outlet on the top of the storage box is used to eliminate the difficulty of removing the top layer of tissue paper due to compression. It is designed to be longer than the long side direction of the upper surface (Patent Document 3). However, in the moisturizing tissue, there is a problem that the tissue paper is difficult to be held in the take-out port due to its high slipperiness and falls into the storage box, making it difficult to pop up. On the other hand, in order to hold tissue paper in the take-out port, when taking measures such as reducing the take-out port and increasing the rigidity of the film arranged in the take-out port, there is a problem that it is easily broken when taking out the tissue paper. Can occur.
本発明の第1の課題は、従来の保湿ティシュペーパーと同等以上の滑らかさ及びしっとり感を有し、かつ、使用時のベタつき感と破れやすさとを軽減したティシュペーパーを提供することである。本発明の第2の課題は、上記のティシュペーパー収納時において、その取り出しやすさ、ポップアップのしやすさを保持しつつ、かつ、取り出す際に破れにくくなるよう構成された収納箱を使用した、ティシュペーパー製品を提供することである。
The first problem of the present invention is to provide a tissue paper that has a smoothness and a moist feeling equivalent to or higher than that of a conventional moisturizing tissue paper, and has reduced stickiness and tearability during use. The second problem of the present invention is that when storing the tissue paper, the storage box configured to be easy to take out, to maintain the ease of pop-up, and to be difficult to tear when taking out, is used. To provide tissue paper products.

2プライのティシュペーパーを構成するシートに規定量の水分を含む薬液を塗布して浸透させることにより、シートのクレープ構造が伸長し、表面の滑らかなティシュペーパーが形成される。また、伸長により紙厚が低くなるとともに繊維密度が高くなるため、繊維間強度が増加し、CD方向の引張強度の高いティシュペーパーとすることができる。従来の保湿ティシューが厚みのある基紙にローション薬液を塗布し、ティシュー表面に皮膜を作り滑らかさを使用者に与えているのに対し、本発明は厚みと薬液塗布量を抑え、クレープ構造を伸長させて表面を滑らかにするもので、これにより従来の保湿ティシュー以上の滑らかさを与えるものである。つまり、ティシュー表面のローション薬液の皮膜を滑らかさを感じさせる最小限の量としてベタつき感を軽減したものである。そのため、乾燥状態における薬剤含有量が従来のローションタイプのティシュペーパーよりも低く、使用時のベタつき感が生じにくいにも関わらず、その効果を奏するのに充分な量の薬剤が含有されていることから、充分なしっとり感、保湿性を保有する。さらには、紙厚が薄いことにより、薬剤含有量に比して柔らかい使用感を有する。
¡By applying and infiltrating a chemical solution containing a specified amount of moisture into the sheet constituting the two-ply tissue paper, the crepe structure of the sheet is extended, and the tissue paper having a smooth surface is formed. Further, since the paper thickness is reduced and the fiber density is increased by the elongation, the strength between fibers is increased, and a tissue paper having a high tensile strength in the CD direction can be obtained. Whereas conventional moisturizing tissue applies a lotion solution to a thick base paper to create a film on the surface of the tissue to give the user smoothness, the present invention suppresses the thickness and the amount of solution applied, and provides a crepe structure. The surface is made smooth by stretching, thereby providing a smoothness higher than that of a conventional moisturizing tissue. In other words, the sticky feeling is reduced as a minimum amount of the lotion solution film on the tissue surface to make it feel smooth. Therefore, the drug content in the dry state is lower than that of conventional lotion type tissue paper, and it contains a sufficient amount of drug to exert its effect even though it does not easily cause stickiness when used. Therefore, it has enough moist and moisturizing properties. Furthermore, since the paper thickness is thin, it has a soft feeling in use as compared with the drug content.
マルチスタンド式インターフォルダの使用により、製造の高速化を行うことができる。マルチスタンド式インターフォルダを使用する場合、製造されるティシュペーパー製品は、需要者がティシュペーパーをCD方向に引き出す形態となる。しかし、従来の保湿ティシューは、非保湿ティシューに比して紙力、特にCD方向の引っ張り強度が高くないことから、マルチスタンド式インターフォルダにより製造された製品においては、引き出し時に破れやすくなる、という問題が想定される。
Acceleration of production can be achieved by using a multi-stand type interfolder. When the multi-stand type interfolder is used, the manufactured tissue paper product has a form in which the consumer pulls out the tissue paper in the CD direction. However, the conventional moisturizing tissue does not have high paper strength, particularly the tensile strength in the CD direction, as compared to the non-humidifying tissue, so that a product manufactured by a multi-stand type interfolder is easily broken when pulled out. A problem is assumed.
本発明におけるティシュペーパー製品においては、上記のようにティシュペーパーをCD方向の引張強度が強く、かつ静摩擦係数の小さいものとするとともに、ティシュペーパーの収納箱として、取り出し口周辺のフィルムに柔軟なものを使用し、取り出し口の大きさを規定したものを使用している。これにより、ティシュペーパーをCD方向に引っ張って取り出しても破れにくく、かつ、最上層が取り出し口から箱内部に落ち込みにくい構成とした。 保湿ティシュペーパーについてマルチスタンド式インターフォルダで折り加工を行う場合、水分を含む連続シートにMD方向に比較的高い引張力をかけ、かつ厚み方向に圧力をかけながら加工するため、従来のロータリー式インターフォルダ使用時と比して、ウェブ嵩を低く抑えることができる。この効果により、非保湿ティシュペーパー製品に多用されるコンパクト型収納箱にも収納可能となる。
In the tissue paper product according to the present invention, as described above, the tissue paper has a strong tensile strength in the CD direction and a small coefficient of static friction, and is flexible as a tissue paper storage box on the film around the outlet. Is used, and the size of the outlet is specified. Thereby, even if the tissue paper is pulled in the CD direction and taken out, it is difficult to break, and the uppermost layer is difficult to fall into the box from the take-out port. When folding with a multi-stand type interfolder for moisture-retaining tissue paper, a continuous sheet containing moisture is processed while applying a relatively high tensile force in the MD direction and applying pressure in the thickness direction. The web bulk can be kept lower than when using a folder. By this effect, it can be stored in a compact storage box frequently used for non-humidifying tissue paper products.
以上のように、本発明は、従来の保湿ティシューと同等以上にしっとりと滑らかな風合いを有するとともに、従来の保湿ティシューよりもベタつき感がなく、かつCD方向の引張強度の高いティシュペーパーを提供するものである。また、ティシュペーパーを収納箱からCD方向に引っ張って取り出すことが可能であることから、マルチスタンド式インターフォルダを用いて高速で製造することが可能な薬液塗布ティシュペーパー製品を提供する。さらに、コンパクト型収納箱に収納された薬液塗布ティシュペーパー製品を提供するものである。
As described above, the present invention provides a tissue paper having a moist and smooth texture equal to or higher than that of a conventional moisturizing tissue, having less stickiness than the conventional moisturizing tissue, and having a high tensile strength in the CD direction. Is. In addition, since tissue paper can be pulled out from the storage box in the CD direction, a chemical-coated tissue paper product that can be manufactured at high speed using a multi-stand type interfolder is provided. Furthermore, the chemical | medical solution application | coating tissue paper products accommodated in the compact type | mold storage box are provided.

Functional agents include softeners, surfactants, inorganic and organic fine particle powders, oily components, and the like. Softeners and surfactants have the effect of imparting flexibility to the tissue and smoothing the surface, and anionic surfactants, cationic surfactants and zwitterionic surfactants are applied. Inorganic and organic fine particle powders have a smooth surface. The oil component has a function of improving lubricity, and higher alcohols such as liquid paraffin, cetanol, stearyl alcohol, and oleyl alcohol can be used.
また機能性薬剤としてポリオールの保湿性を助けたり、維持させる薬剤として親水性高分子ゲル化剤、コラーゲン、加水分解コラーゲン、加水分解ケラチン、加水分解シルク、ヒアルロン酸若しくはその塩、セラミド等の1種以上を任意の組合せ等の保湿剤を加えることができる。
In addition, as a functional agent, one of a hydrophilic polymer gelling agent, collagen, hydrolyzed collagen, hydrolyzed keratin, hydrolyzed silk, hyaluronic acid or a salt thereof, ceramide, etc. A moisturizing agent such as any combination can be added.

〔塗布量〕
塗布量は、操業中にプライ後の薬液を塗布しない場合の各々のシート米坪と、対応する塗布した直後の各々のシート米坪との差異により算出した。
(塗布量g/m2)=(塗布直後の米坪g/m2)-(塗布しない場合の米坪g/m2)
両表層の塗布量、もしくは両面の塗布量の合計とは、プライされたティシュペーパーのシートの単位面積当たりの塗布量の合計であり、各シートの塗布量を加算したものとする。 [Amount of application]

静摩擦係数を低下させる原理としては、以下のことが考えられる。本発明では、1次原反連続シートを2枚プライし、カレンダー処理によりクレープの山部をならし、クレープ山部のけば立ちをなだらかにすることでシート表面を平滑にした後、ローション薬液を好ましくは転写方式により塗布する。塗布された2次原反シートは、一定のテンションがかかったまま保管され、折畳み加工されるまでの間に、シーズニングされる。この間に、時間とともにローション薬液は、平面的に、かつ厚み方向に、紙層内部に均一になるように広がっていく。その後工程で、マルチスタンド式インターフォルダによる折畳みが行われる場合、プライ原反から2次連続シートを引き出し、折畳み、引っ張りながらプルコンベアで押える工程を経て断裁する。この折畳み工程では、塗布しシーズニングされ紙層中に水分が吸収された状態で、折畳み加工に入る。シーズニング、及びその後のテンションと厚み方向の圧力により、シート表面のクレープによる凸凹は小さくなり、シート同士の摩擦は低減する。
The following can be considered as a principle for reducing the static friction coefficient. In the present invention, two primary raw fabric continuous sheets are plyed, the crepe peak is smoothed by calendering, the sheet surface is smoothed by smoothing the crepe peak, and then the lotion chemical solution Is preferably applied by a transfer method. The applied secondary raw sheet is stored under a certain tension and seasoned until it is folded. During this time, the lotion chemical solution spreads over time so as to be uniform inside the paper layer in a planar and thickness direction. In the subsequent process, when folding by the multi-stand type interfolder is performed, the secondary continuous sheet is pulled out from the ply raw fabric, folded, and cut through a process of pressing with a pull conveyor while pulling. In this folding process, folding processing is started in a state in which it is coated and seasoned and moisture is absorbed in the paper layer. Due to seasoning and subsequent tension and pressure in the thickness direction, unevenness due to creping on the sheet surface is reduced, and friction between sheets is reduced.

MMD is an average deviation (unit: dimensionless) of the friction coefficient μ. MMD is one of the indices of smoothness. The smaller the numerical value, the smoother, and the larger the numerical value, the less smooth.
As a method for measuring the MMD value, as shown in FIG. 11A, a tension of 20 g / cm is applied to the contact surface of thefriction element 112 in a predetermined direction (downward and rightward in FIG. 11A). While being brought into contact with the surface of the tissue paper 111, which is the measurement sample, at a contact pressure of 25 g, it is moved 2 cm at a speed of 0.1 cm / s in the same direction as the direction in which the tension is applied. The friction coefficient at this time was measured using a friction feeling tester KES-SE (manufactured by Kato Tech Co., Ltd.), and the average deviation of the friction coefficient μ at a friction distance of 2 cm (moving distance was 3 cm, excluding 5 mm before and after each). Was defined as the MMD value.
Thefriction element 112 has 20 piano wires P with a diameter of 0.5 mm adjacent to each other, and has a contact surface formed so that the length and width are both 10 mm. The contact surface is formed with a unit bulging portion whose tip is formed of 20 piano wires P (curvature radius 0.25 mm).

A plastic plate having a weight of 30 g and a size of 130 mm × 250 mm was placed on the tissue paper bundle, and the heights of the four corners were averaged to obtain the web bulk value.

If the web bulk is too low, it becomes difficult for the user to put the finger deeply out of the take-out opening when taking out the uppermost tissue from the storage box, making it difficult to take out. If the web is too bulky, it cannot be stored in a compact storage box (box height of about 55 to 65 mm), and manufacturing costs and transportation costs increase, or the web is compressed during storage and is compact. In order to store in the storage box, the top layer must be pulled out with a strong force when taking out, and there is a problem that the tissue paper is easily torn.

The lower end portion of the upper flap 202f is overlapped on the outer side of the upper end portion of the lower flap 203f, and the overlapped portion is fixed by the adhesive.
箱の内寸法は、上面の長辺の長さを収納されるウェブの長手方向の長さより5~20mm、特に8~15mm長くするのが好ましい。収納箱内部において、長手方向に隙間をもたせることで、箱内面とティシュペーパー間にほとんど抵抗を生じることなくティシュペーパーを取り出すことが可能となる。
The inner dimension of the box is preferably 5 to 20 mm, particularly 8 to 15 mm longer than the length in the longitudinal direction of the web to be stored. By providing a gap in the longitudinal direction inside the storage box, it becomes possible to take out the tissue paper with almost no resistance between the inner surface of the box and the tissue paper.
収納箱の高さは収納されるウエブ組数に合わせ、本発明の範囲内で任意に決定できるが、経済性や使用の利便性を考慮するとウエブ組数を150~300組とし、これに伴い収納箱の高さを50~120mmとするのが好ましい。
The height of the storage box can be arbitrarily determined within the scope of the present invention in accordance with the number of web sets to be stored. However, considering the economy and convenience of use, the number of web sets is set to 150 to 300 sets. The height of the storage box is preferably 50 to 120 mm.
さらに言えば、収納箱の高さは、製造コスト、輸送コストの削減のため、50~80mmの高さとするのが好ましく、より好ましくは55~65mmのコンパクト型とすることが好ましい。
Furthermore, the height of the storage box is preferably 50 to 80 mm, more preferably 55 to 65 mm, in order to reduce manufacturing costs and transportation costs.
収納箱201の上面202には、ミシン目などの切りこみ目が予め形成されており、使用開始時にその切りこみ目で囲まれる蓋部分202bを剥ぎ取ることにより取り出し窓(開口)202aが形成されるようになっている。蓋部分202bを、図14,15に示すように、その略一辺が切り取られずに谷折り線202gとなるように構成してもよい。このような構成とすることで、蓋部分2bを取り出し窓202aの蓋として利用することができる。また、取り出し窓202aを予め開口させ、蓋部分202bを有さない構造としても良い。取り出し窓202aの長辺方向の長さは、収納されるウェブの長手方向の長さの50~70%、特に55~65%とする。また、取り出し窓202aの短辺方向の長さは、ウェブの短手方向の長さの35~55%、特に40~50%とすることが好ましい。
A cutout such as a perforation is formed in advance on the upper surface 202 of the storage box 201, and an extraction window (opening) 202a is formed by peeling off the lid portion 202b surrounded by the cutout at the start of use. It has become. As shown in FIGS. 14 and 15, the lid portion 202 b may be configured so as to be a valley fold line 202 g without being cut off at substantially one side. By setting it as such a structure, the cover part 2b can be utilized as a cover of the extraction window 202a. Alternatively, the take-out window 202a may be opened in advance and the lid portion 202b may not be provided. The length in the long side direction of the take-out window 202a is 50 to 70%, particularly 55 to 65% of the length in the longitudinal direction of the web to be stored. The length in the short side direction of the take-out window 202a is preferably 35 to 55%, particularly 40 to 50% of the length in the short side direction of the web.
取り出し窓202aには、箱の内側から、その全体にわたりフィルム状のカバーシート202cがホットメルト接着剤等により張り付けられ、カバーシート202cにおける取り出し窓202aにより取り囲まれる部分には、箱1の長辺方向に沿うスリット202sが形成されている。スリット202sは、収納されるウェブの長手方向の長さの45~65%、特に50~60%とする。スリット202sは、特に、長辺方向、短辺方向、ともに取り出し窓202aの中央近傍に配されるのが好ましい。
A film-like cover sheet 202c is attached to the take-out window 202a from the inside of the box with a hot-melt adhesive or the like, and a portion of the cover sheet 202c surrounded by the take-out window 202a has a long side direction of the box 1 A slit 202s is formed. The slit 202s is 45 to 65%, particularly 50 to 60%, of the length in the longitudinal direction of the web to be stored. The slit 202s is particularly preferably arranged in the vicinity of the center of the extraction window 202a in both the long side direction and the short side direction.
カバーシートを形成する素材としては、ポリエチレン、ポリプロピレン、ポリエステル等の樹脂からなる樹脂製フィルムシート、又はこれらを積層した積層の樹脂製フィルムシート、フィルムシートと薄葉紙等を積層したラミネートフィルムシート、樹脂製繊維からなる合成紙シート等が挙げられる。取り出し性を考慮すると樹脂製フィルムシートが好ましく、特に柔軟性に富み、かつ製造コストの低い低密度ポリエチレンフィルム(LDPE)を好適に使用できる。
As a material for forming the cover sheet, a resin film sheet made of a resin such as polyethylene, polypropylene, polyester, or a laminated resin film sheet obtained by laminating these, a laminated film sheet laminated with a film sheet and a thin paper, etc. Examples include synthetic paper sheets made of fibers. A resin film sheet is preferable in consideration of the take-out property, and a low-density polyethylene film (LDPE) that is particularly flexible and low in production cost can be suitably used.
フィルムの厚みは33~38μmとすることが望ましい。また、フィルムの縦方向の剛軟度を0.8~1.4gf/10mm、特に1.0~1.2gf/10mmとすることが好ましい。剛軟度は、JIS L 1096 E法に記載のハンドルオメータ法に基づいて測定したものであるが、試験片は縦100mm×横10mmの大きさとし、クリアランスは5mmで実施した。1プライで縦方向10回の平均値を小数点2桁とし、cN/100mmを単位として表した。フィルムの縦方向はフィルムのスリット方向と一致する。フィルムの縦方向の剛軟度を1.4gf/10mmより高くすると、ティシュペーパーの取り出し時に破れやすくなり、また、0.8gf/10mmより低くすると取り出し口にティシュペーパーを保持しづらくなり、ポップアップが困難となる。
The film thickness is preferably 33-38 μm. Further, it is preferable that the longitudinal bending resistance of the film is 0.8 to 1.4 gf / 10 mm, particularly 1.0 to 1.2 gf / 10 mm. The bending resistance was measured based on the handle ohmmeter method described in JIS L 1096 E method. The test piece was 100 mm long × 10 mm wide, and the clearance was 5 mm. The average value of 10 times in 1 ply in the vertical direction was represented by 2 digits of decimal point and expressed in units of cN / 100 mm. The longitudinal direction of the film coincides with the slit direction of the film. If the bending resistance of the film in the longitudinal direction is higher than 1.4 gf / 10 mm, it will be easy to tear when taking out the tissue paper, and if it is lower than 0.8 gf / 10 mm, it will be difficult to hold the tissue paper in the outlet and pop-up will occur. It becomes difficult.
さらに、取り出し時のティシュペーパーの滑りを良くして抵抗を抑えるため、フィルム横方向-ティシュペーパー(取出し方向)間の静摩擦係数は0.20~0.30、より好適には0.23~0.28とする。フィルム横方向とはフィルム縦方向とフィルム平面上で垂直な方向を意味する。フィルム-ティシュペーパー間の静摩擦係数は、以下の方法で測定した。フィルムを収納箱内側の面が外側に来るように、斜面方向がフィルム横方向になるようにアクリル板に貼り付ける。2プライのまま100gの分銅にティシュペーパーを巻きつけ、斜面方向がティシュー取出し方向になるようにアクリル板上のフィルムに乗せる。アクリル板を傾け、おもりが滑り落ちる角度を測定する。角度測定は10回実施し、平均角度を算出し、そのタンジェント値を静摩擦係数とした。
Furthermore, the coefficient of static friction between the lateral direction of the film and the tissue paper (the removal direction) is 0.20 to 0.30, and more preferably 0.23 to 0 in order to improve the slip of the tissue paper at the time of taking out and suppress the resistance. .28. The film transverse direction means a direction perpendicular to the film longitudinal direction and the film plane. The coefficient of static friction between film and tissue paper was measured by the following method. The film is affixed to the acrylic plate so that the slope direction is the lateral direction of the film so that the inner surface of the storage box is on the outside. Wrap tissue paper around a 100 g weight with 2 plies, and place it on the film on the acrylic plate so that the slope direction is the tissue removal direction. Tilt the acrylic plate and measure the angle at which the weight slides down. The angle measurement was performed 10 times, the average angle was calculated, and the tangent value was taken as the static friction coefficient.

ティシュペーパーの取り出し時にかかる抵抗を一定範囲に規定することで、取り出し時の破れを最低限に減じることができる。ティシュペーパーの取り出し抵抗は、以下の方法で測定する。プッシュブルゲージのゲージ先端にティシュペーパーの中央先端部を固定し、下面を固定した収納箱よりティシュペーパーを、0.4~0.6秒の時間をかけ一定速度で垂直に取り出して、その最大抵抗値を測定した。取り出すティシュペーパーは最上層から1組目から5組目までの計5組、及び11組目から15組目までの計5組とし、上記プッシュブルゲージにおける測定値を平均して、取り出し抵抗値とした。取り出し抵抗は70gf以下、より好適には50~70gfとするのが望ましい。 [Tissue paper removal resistance]
By setting the resistance applied when taking out the tissue paper within a certain range, it is possible to minimize tearing during the taking out. The tissue paper take-out resistance is measured by the following method. Secure the center tip of tissue paper to the gauge tip of the pushbull gauge, and take the tissue paper vertically from the storage box with the bottom surface fixed at a constant speed over a period of 0.4 to 0.6 seconds. The resistance value was measured. The tissue paper to be taken out is a total of 5 sets from the first set to the 5th set from the top layer, and a total of 5 sets from the 11th set to the 15th set. It was. The take-out resistance is preferably 70 gf or less, more preferably 50 to 70 gf.

When the chemical spraying method is used as the chemical coating means, the spraying means is not particularly limited, but may be a nozzle dampening method or a rotor dampening spraying method. The processing speed is 100 to 1100 m / min, preferably 350 to 1050 m / min, and more preferably 450 to 1000 m / min.
薬液塗布後のシートは、コンタクトエンボスコロ18及びコロロール19に供され、2プライの連続シートにコンタクトエンボス(ナーリング)処理を施すことにより固定される。このとき、薬液塗布量の少ない連続シート32が、コンタクトエンボスコロ18に接触するように配置される。コンタクトエンボスは、両側部から紙幅に対して1/10~1/20の位置に幅1~10mmで縦方向に一様に施されるのが好ましい。プライを接着剤等で固定するなど、公知の方法のいずれを使用してもよいが、接着剤を使用する場合、肌触りが固くなりやすい、薬液塗布時に剥がれやすい、等の問題があるため、コンタクトエンボスの使用がより好ましいといえる。
The sheet after applying the chemical solution is supplied to the contact embossing roller 18 and the roller roll 19 and fixed by subjecting the two-ply continuous sheet to a contact embossing (knurling) process. At this time, the continuous sheet 32 with a small amount of chemical solution applied is disposed so as to contact the contact embossing roller 18. The contact embossing is preferably uniformly applied in the longitudinal direction with a width of 1 to 10 mm at a position of 1/10 to 1/20 with respect to the paper width from both sides. Any of the known methods such as fixing the ply with an adhesive may be used. However, when using an adhesive, there is a problem that the touch tends to become hard, and it is easy to peel off when applying a chemical solution. It can be said that the use of embossing is more preferable.
コンタクトエンボスを付与した2プライの連続シートは、直接ロータリー式インターフォルダ等に供されて折り加工を施された後に製品サイズに裁断されるか、または、スリッター20により製品幅にカットされた後、ワインディングドラム21により巻き取り二次原反ロール22とされ、折り加工が施され、紙箱への収納がなされる。
なお、本形態ではコンタクトエンボス前に薬液を塗布する構成をとっているが、コンタクトエンボス後に薬液を塗布する構成としてもよい。 2 ply continuous sheet with contact embossing is cut directly into product size after being subjected to folding processing by being directly applied to a rotary interfolder or the like, or after being cut into product width byslitter 20, The winding roll 21 makes a take-up secondary raw roll 22 which is folded and stored in a paper box.
In this embodiment, the chemical solution is applied before the contact embossing. However, the chemical solution may be applied after the contact embossing.

In this embodiment, the chemical solution is applied before the contact embossing. However, the chemical solution may be applied after the contact embossing.
薬液塗布は、オンマシン、オフマシンのいずれで行ってもよい。また、薬液塗布手段を抄紙機の一次連続シートの巻き取り工程前(カレンダー処理を行う場合は、カレンダー処理の前後いずれでもよい)、インターフォルダの折り加工前に設けてもよい。さらに、薬液塗布手段は単独に限られず、複数の工程において薬液塗布を行う構成としてもよい。
Chemical liquid application may be performed either on-machine or off-machine. Further, the chemical solution applying means may be provided before the winding process of the primary continuous sheet of the paper machine (if the calendar process is performed, it may be before or after the calendar process) or before the interfolder is folded. Furthermore, the chemical solution application means is not limited to a single one, and may be configured to apply the chemical solution in a plurality of steps.

上述の二次原反ロールは、特にティシュペーパー製品においては折り加工工程に供される。折り加工工程としては、ロータリー式インターフォルダ、マルチスタンド式インターフォルダ等公知の方法を使用することができるが、生産性の高いマルチスタンド式インターフォルダの使用がより好ましい。また、本発明においては、前述のように、ティシュペーパーの静摩擦係数を低く、かつウェブ嵩を低くする必要があることから、マルチスタンド式インターフォルダの使用が特に好ましいといえる。 [Multi-stand type inter folder]
The secondary raw roll described above is subjected to a folding process particularly in tissue paper products. As the folding process, a known method such as a rotary interfolder or a multi-stand interfolder can be used, but it is more preferable to use a multi-stand interfolder with high productivity. In the present invention, as described above, it is necessary to use a multi-stand type interfolder because the static friction coefficient of tissue paper needs to be low and the web bulk needs to be low.

In the present invention, as described above, it is necessary to use a multi-stand type interfolder because the static friction coefficient of tissue paper needs to be low and the web bulk needs to be low.
二次原反ロール22は、マルチスタンド式インターフォルダに多数セットされ、セットされた二次原反ロール22から二次連続シートを繰り出して折り畳むと共に積層することによってティシュペーパー束が製造される。以下では、そのマルチスタンド式インターフォルダの一例について説明する。
A large number of secondary web rolls 22 are set in a multi-stand type interfolder, and a secondary continuous sheet is drawn out from the set secondary web roll 22 to be folded and laminated to produce a tissue paper bundle. Hereinafter, an example of the multi-stand type interfolder will be described.
図2及び図3に、マルチスタンド式インターフォルダの一例を示した。図中の符号2は、マルチスタンド式インターフォルダ1の図示しない二次原反ロール支持部にセットされた二次原反ロール22,22…を示している。この二次原反ロール22,22…は、必要数が図示平面と直交する方向(図2における水平方向、図3における紙面前後方向)に横並びにセットされている。各二次原反ロールRは、上述のティシュペーパー製品用二次原反ロールの製造設備、製造方法でティシュペーパー製品幅にスリットが入れられており、ティシュペーパー製品の複数倍幅、図示例では2倍幅で巻き取られ、セットされている。
2 and 3 show an example of the multi-stand type interfolder. Reference numeral 2 in the drawing denotes secondary raw rolls 22, 22... Set on secondary raw roll support portions (not shown) of the multi-stand type interfolder 1. These secondary raw rolls 22, 22... Are set side by side in the direction (the horizontal direction in FIG. 2, the front-to-back direction in FIG. 3) in which the required number is orthogonal to the illustrated plane. Each secondary raw roll R has slits in the width of tissue paper product in the above-described manufacturing equipment and manufacturing method of the secondary raw roll for tissue paper products. It is wound and set in double width.
二次原反ロール22から巻き出された連続する帯状の二次連続シート63A及び63Bは、ガイドローラG1、G1等のガイド手段に案内されて折畳機構部60へ送り込まれる。また、折畳機構部60には、図4に示すように、折板P,P…が必要数並設されてなる折板群64が備えられている。各折板Pに対しては、一対の連続する二次連続シート63A又は63Bを案内するガイドローラG2,G2やガイド丸棒部材G3,G3が、それぞれ適所に備えられている。さらに、折板P,P…の下方には、折り畳みながら積み重ねられた積層帯67を受けて搬送するコンベア65が備えられている。
The continuous belt-like secondary continuous sheets 63A and 63B unwound from the secondary web roll 22 are guided by guide means such as guide rollers G1 and G1 and fed into the folding mechanism section 60. Moreover, the folding mechanism part 60 is provided with the folding plate group 64 in which the required number of folding plates P, P ... are arranged in parallel as shown in FIG. For each folded plate P, guide rollers G2, G2 and guide round bar members G3, G3 for guiding a pair of continuous secondary continuous sheets 63A or 63B are respectively provided at appropriate positions. Further, below the folded plates P, P..., A conveyor 65 is provided that receives and conveys the laminated band 67 that is stacked while being folded.
この種の折板P,P…を用いた折畳機構は、例えば、米国特許4052048号特許明細書等によって公知の機構である。この種の折畳機構は、図5に示すように、各連続する二次連続シート63A,63B…を、Z字状に折り畳みながら、かつ隣接する連続する二次連続シート63A,63B…の側端部相互を掛け合わせながら積み重ねる。
A folding mechanism using this type of folded plates P, P... Is a mechanism known from, for example, US Pat. As shown in FIG. 5, this type of folding mechanism folds each continuous secondary continuous sheet 63A, 63B... In the Z-shape and is adjacent to the adjacent secondary continuous sheets 63A, 63B. Stack the ends together.
図6~図9に、折畳機構部60の特に折板Pに関する部位を、詳しく示した。本折畳機構部60においては、各折板Pに対して、一対の連続する二次連続シート63A及び63Bが案内される。この際、連続する二次連続シート63A及び63Bは、ガイド丸棒部材G3,G3によって、側端部相互が重ならないように位置をずらされながら案内される。
FIGS. 6 to 9 show in detail the portions of the folding mechanism 60, particularly the folded plate P. FIG. In the folding mechanism 60, a pair of continuous secondary continuous sheets 63A and 63B are guided for each folded plate P. At this time, the continuous secondary continuous sheets 63A and 63B are guided by the guide round bar members G3 and G3 while being shifted in position so that the side end portions do not overlap each other.
折板Pに案内された時点で下側に重なっている連続する二次連続シートを第1の連続する二次連続シート63Aとし、上側に重なっている連続する二次連続シートを第2の連続する二次連続シート63Bとすると、これら連続する二次連続シート63A及び63Bは、図5及び図7に示すように、第1の連続する二次連続シート63Aの第2の連続する二次連続シート63Bと重なっていない側端部e1が、折板Pの側板P1によって、第2の連続する二次連続シート63Bの上側に折り返されるとともに、図5及び図8に示すように、第2の連続する二次連続シート63Bの第1の連続する二次連続シート63Aと重なっていない側端部e2が、折板PのスリットP2から折板P下に引き込まれるようにして下側に折り返される。この際、図5及び図9に示すように、上流の折板Pにおいて折り畳みながら積み重ねられた連続する二次連続シート63Aの側端部e3(e1)が、折板PのスリットP2から第2の連続する二次連続シート63Bの折り返し部分間に案内される。このようにして、各連続する二次連続シート63A,63B…は、Z字状に折り畳まれるとともに、隣接する連続する二次連続シート63A及び63Bの側端部相互が掛け合わされ、したがって、製品使用時において、最上位のティシュペーパーを引き出すと、次のティシュペーパーの側端部が引き出されることになる。
The continuous secondary continuous sheet that overlaps the lower side when guided by the folded plate P is the first continuous secondary continuous sheet 63A, and the continuous secondary continuous sheet that overlaps the upper side is the second continuous sheet. As shown in FIGS. 5 and 7, these continuous secondary sheets 63A and 63B are second continuous secondary continuous sheets of the first continuous secondary continuous sheet 63A. The side end e1 that does not overlap the sheet 63B is folded back to the upper side of the second continuous secondary continuous sheet 63B by the side plate P1 of the folded plate P, and as shown in FIG. 5 and FIG. The side end e2 of the continuous secondary continuous sheet 63B that does not overlap with the first continuous secondary continuous sheet 63A is folded downward so as to be drawn under the folded plate P from the slit P2 of the folded plate P. . At this time, as shown in FIGS. 5 and 9, the side end e3 (e1) of the continuous secondary continuous sheet 63A stacked while being folded in the upstream folded plate P is second from the slit P2 of the folded plate P. Are guided between the folded portions of the secondary continuous sheet 63B. In this way, each continuous secondary continuous sheet 63A, 63B... Is folded in a Z shape and the side ends of adjacent continuous secondary continuous sheets 63A and 63B are crossed together, so that the product is used. In some cases, when the top tissue paper is pulled out, the side edge of the next tissue paper is pulled out.
以上のようにしてマルチスタンド式インターフォルダ6で得られた積層帯70は、図2に示すように、後段の切断手段66において流れ方向FLに所定の間隔をおいて裁断(切断)されてティシュペーパー束67aとされ、図10(a)に示すように、このティシュペーパー束30aは、更に後段設備において収納箱Bに収納される。なお、以上のようなマルチスタンド式インターフォルダ1では、積層帯70の紙の方向は、流れ方向FLに沿って縦方向(MD方向)となっており、流れ方向と直交する方向に沿って横方向(CD方向)となっている。このため、積層帯70を所定の長さに切断して得られたティシュペーパー束67aを構成するティシュペーパーの紙の方向は、図10(a)に示すように、ティシュペーパーの折り畳み方向に沿って横方向(CD方向)となり、ティシュペーパーの折り畳み方向と直交する方向に沿って縦方向(MD方向)となる。
As shown in FIG. 2, the laminated band 70 obtained in the multi-stand type interfolder 6 as described above is cut (cut) at a predetermined interval in the flow direction FL by the cutting means 66 at the subsequent stage, and the tissue is cut. This tissue paper bundle 30a is further stored in the storage box B in the subsequent equipment as shown in FIG. 10 (a). In the multi-stand type interfolder 1 as described above, the paper direction of the laminated band 70 is the vertical direction (MD direction) along the flow direction FL, and the horizontal direction along the direction orthogonal to the flow direction. Direction (CD direction). For this reason, the direction of the paper of the tissue paper constituting the tissue paper bundle 67a obtained by cutting the laminated band 70 into a predetermined length is along the folding direction of the tissue paper, as shown in FIG. The horizontal direction (CD direction) and the vertical direction (MD direction) along the direction orthogonal to the folding direction of the tissue paper.
図10(b)に、収納箱Bにティシュペーパー束67aを収納して成る製品の一例を示した。収納箱Bの上面にはミシン目Mが設けられており、このミシン目Mで収納箱B上面の一部を破断することにより収納箱Bの上面が開口するようになっている。この開口は中央にスリットを有するフィルムFによって覆われており、このフィルムFに設けられたスリットを介してティシュペーパーTを取出すことができるようになっている。
FIG. 10 (b) shows an example of a product in which the tissue paper bundle 67a is stored in the storage box B. A perforation M is provided on the upper surface of the storage box B, and a part of the upper surface of the storage box B is broken by the perforation M so that the upper surface of the storage box B is opened. The opening is covered with a film F having a slit at the center, and the tissue paper T can be taken out through the slit provided in the film F.
ところで、前述したように、ティシュペーパー束67aを構成するティシュペーパーの紙の方向は、ティシュペーパーの折り畳み方向に沿って横方向(CD方向)となるため、図10(b)に示すように、ティシュペーパーTを収納箱Bから引き出す際には、その引き出し方向は、ティシュペーパーTの横方向(CD方向)と沿うようになっている。
By the way, as described above, the direction of the paper of the tissue paper constituting the tissue paper bundle 67a is the horizontal direction (CD direction) along the folding direction of the tissue paper, as shown in FIG. When the tissue paper T is pulled out from the storage box B, the pulling direction is along the horizontal direction (CD direction) of the tissue paper T.

本発明に係るティシュペーパーは、市販の保湿ティシューと比してCD方向の乾燥引張強度、湿潤引張強度が高い値を示した。またCD方向の湿潤引張強度については、従来の汎用タイプのティシュペーパーより高い値を示した。また、ソフトネス、静摩擦係数が市販製品と比して低く、なめらかで柔らかい紙質を有することが示された。
官能評価において、本発明に係るティシュペーパーは、厚み感に優れたものではないものの、保湿ティシューと同等以上のやわらかさ、なめらかさ、しっとり感を有し、かつ、保湿ティシューにみられるベタつき感が軽減されていることが分かった。 The tissue paper according to the present invention showed high values of the dry tensile strength and the wet tensile strength in the CD direction as compared with a commercially available moisturizing tissue. The wet tensile strength in the CD direction was higher than that of conventional general-purpose tissue paper. It was also shown that the softness and static friction coefficient were lower than those of commercial products, and the paper was smooth and soft.
In sensory evaluation, the tissue paper according to the present invention is not excellent in thickness, but has a softness, smoothness, moist feeling equal to or higher than that of a moisturizing tissue, and a sticky feeling seen in a moisturizing tissue. I found out that it was alleviated.

In sensory evaluation, the tissue paper according to the present invention is not excellent in thickness, but has a softness, smoothness, moist feeling equal to or higher than that of a moisturizing tissue, and a sticky feeling seen in a moisturizing tissue. I found out that it was alleviated.
特に本発明に係るティシュペーパーについて良好な滑り性を有する要因については、次のことが考えられる。ティシュペーパーに塗布した薬液の浸透性によっても異なるが、親水性、親油性の両成分を含む薬液を塗布した場合、親水性成分がパルプ内に吸収されるとともに親油性成分が紙表面に残りやすく、表面の摩擦が軽減されると考えられる。しかし、従来の保湿ティシューのように薬液塗布量を増やすと親水性成分が充分にパルプ内に吸収されず表面に残るため、親油性成分の摩擦軽減効果が薄れるとともに、親水性成分(グリセリンなど)の粘性により滑り性が低下するものと推測される。
Especially, the following can be considered as factors that have good slipperiness for the tissue paper according to the present invention. Although it depends on the permeability of the chemical applied to tissue paper, when a chemical containing both hydrophilic and lipophilic components is applied, the hydrophilic components are absorbed into the pulp and the lipophilic components tend to remain on the paper surface. It is considered that surface friction is reduced. However, increasing the amount of chemical solution applied as in conventional moisturizing tissue, the hydrophilic component is not sufficiently absorbed into the pulp and remains on the surface, reducing the friction reducing effect of the lipophilic component and the hydrophilic component (such as glycerin). It is presumed that the slipperiness decreases due to the viscosity of.
ティシュペーパーの取り出し抵抗、及びティシュペーパーの取り出しやすさについて、実施例1~7において、比較例1~3より有意に良好な結果が得られた。これにより、ティシュペーパー取り出し時の滑りがよく、スムーズに取り出せるため、取り出し時の破れの危険性が低減したといえる。比較例4は、ウェブと箱上部内側面の間に間隙を有し、ウェブがふんわりと入れてあることから、シート間の摩擦が生じにくく、取り出し抵抗が小さい。しかし、比較例4は、使用時のシートの落ち込みが生じやすく、ポップアップがしにくい、という問題がある。これに比して、実施例1~4は、滑りを良くしても、使用途中のティシュペーパーがスリット部分から収納箱内部に落ち込むこともなく、使用途中においても使用感を損なわないことが分かった。
また、比較例2~4において、使用時の破れが生じやすいのに対し、実施例1~7は破れが生じにくいことが判明した。 With respect to the resistance to taking out the tissue paper and the ease of taking out the tissue paper, the results of Examples 1 to 7 were significantly better than those of Comparative Examples 1 to 3. Thereby, it can be said that the risk of tearing at the time of taking out was reduced because slipping when taking out the tissue paper was good and the tissue paper could be taken out smoothly. In Comparative Example 4, there is a gap between the web and the inner surface of the upper portion of the box, and the web is softly inserted. Therefore, friction between the sheets hardly occurs, and the take-out resistance is small. However, the comparative example 4 has a problem that the sheet is likely to drop during use and is difficult to pop up. In comparison, Examples 1 to 4 show that even when slipping is improved, tissue paper in use does not fall into the storage box from the slit portion, and the feeling of use is not impaired even during use. It was.
In Comparative Examples 2 to 4, it was found that breakage during use was likely to occur, whereas in Examples 1 to 7, breakage was less likely to occur.
また、比較例2~4において、使用時の破れが生じやすいのに対し、実施例1~7は破れが生じにくいことが判明した。 With respect to the resistance to taking out the tissue paper and the ease of taking out the tissue paper, the results of Examples 1 to 7 were significantly better than those of Comparative Examples 1 to 3. Thereby, it can be said that the risk of tearing at the time of taking out was reduced because slipping when taking out the tissue paper was good and the tissue paper could be taken out smoothly.
