Description
本発明は、トイレットペーパーに関する。 The present invention relates to toilet paper.
洗浄機能付きトイレともいわれるシャワートイレの普及にともない、トイレットペーパーにおいては、シャワートイレにおける使用に適することも求められている(下記、特許文献1)。
With the widespread use of shower toilets that are also called toilets with a cleaning function, toilet paper is also required to be suitable for use in shower toilets (
シャワートイレに適するトイレットペーパーは、消費者が使用した際の安心感が得られる3プライや4プライといった多プライ品が望ましいとされる。 It is said that multi-ply products, such as 3-ply and 4-ply products, are desirable as toilet paper suitable for shower toilets so that consumers can feel secure when using them.
ところで、トイレットペーパーは、一般に繊維長の短い広葉樹由来のパルプと、繊維長の長い針葉樹由来のパルプを混合した繊維原料から製造され、主に、柔らかさや表面性を向上させやすい広葉樹由来のパルプを多く含むものが一般的である。 By the way, toilet paper is generally produced from a hardwood-derived pulp having a short fiber length and a fiber raw material obtained by mixing a long-fiber-derived softwood-derived pulp, and mainly hardwood-derived pulp which is easy to improve its softness and surface property. It is common to include many.
また、白色度を高めるため繊維原料であるパルプを、塩素や二酸化塩素、次亜塩素酸ソーダなどの塩素系漂白薬品を用いて漂白することが行われているが、人体への安心感や環境への配慮を重視する消費者において、塩素系漂白薬品を使わないパルプを原料とする環境等に配慮した製品の要望もある。 In addition, in order to increase whiteness, pulp, which is a fiber raw material, is bleached using chlorine-based bleaching chemicals such as chlorine, chlorine dioxide, and sodium hypochlorite. There is also a demand for environmentally friendly products made from pulp that does not use chlorine-based bleaching chemicals, for consumers who place great importance on consideration.
しかし、塩素系漂白薬品を用いて漂白していないパルプはリグニンが多く残り、また、繊維が固く、これを主たる繊維原料としたトイレットペーパーは、固さや表面のざらつきが感じられやすくなりやすい。 However, pulp that has not been bleached with a chlorine-based bleaching agent has a large amount of lignin, and the fiber is hard, and toilet paper using this as the main fiber raw material tends to have a feeling of hardness and surface roughness.
一方、柔らかさを感じやすくするために広葉樹パルプの配合量をより多くして紙の強度を下げることが知られるが、広葉樹パルプの配合量を多くすると水解性が悪化しやすい。特に、多プライ品は水解性が悪化しやすいため、広葉樹パルプの配合量を多くするとシャワートイレでの使用に適さなくなってくるおそれがある。 On the other hand, it is known to increase the blending amount of hardwood pulp to lower the strength of the paper in order to make it easier to feel softness. However, if the blending amount of hardwood pulp is increased, the water degradability tends to deteriorate. In particular, since a multi-ply product is liable to deteriorate in water decomposability, there is a possibility that it will not be suitable for use in a shower toilet if the amount of hardwood pulp is increased.
そこで、本発明の主たる課題は、シャワートイレで使用するような場面において安心できる厚み感があり、柔らかさが十分で、さらに水解性に優れ、使用時における人体への安心感がある、トイレットパーパーを提供することにある。 Therefore, the main problem of the present invention is to have a feeling of thickness that can be relieved when used in a shower toilet, sufficient softness, further excellent in water disintegration, and a sense of security for the human body during use. To provide.
上記課題を解決した第一の手段は、
3〜4プライのトイレットペーパーであって、
繊維の80〜100質量%が酸素蒸解され塩素漂白されていない針葉樹クラフトパルプであり、
カチオン性脂肪酸アミド系柔軟剤を含み、
1プライの坪量が12.5〜16.0g/m2であり、
1プライの紙厚が120〜150μmであり、トイレットペーパー全体としての紙厚が400〜600μmであり、
水解性が10秒以下である、
ことを特徴とするトイレットペーパーである。
The first means for solving the above problems is
3-4 ply toilet paper,
80-100% by mass of the fiber is a softwood kraft pulp that has been oxygen-cooked and not bleached with chlorine,
Including cationic fatty acid amide softener,
The basis weight of 1 ply is 12.5-16.0 g / m 2 ,
The paper thickness of one ply is 120 to 150 μm, the paper thickness of the entire toilet paper is 400 to 600 μm,
Water degradability is 10 seconds or less,
It is a toilet paper characterized in that.
以上の本発明によれば、シャワートイレで使用するような場面において安心できる厚み感があり、柔らかさが十分で、さらに水解性に優れ、使用時における人体への安心感がある、トイレットパーパーが提供される。 According to the present invention described above, there is a thickness feeling that can be relieved in a situation where it is used in a shower toilet, sufficient softness, further excellent in water decomposability, and a feeling of safety to the human body during use, a toilet paper Provided.
本実施形態に係るトイレットペーパーは、3プライ又は4プライである。つまり、3枚又は4枚が重ねられているものである。3プライ又は4プライのような2プライを超える多プライとすることで、各プライを薄くしつつも全体の紙厚が厚くなり、特に「柔らかさ」が感じられやすいものとしつつ、破れにくい安心感のあるものとすることができる。 The toilet paper according to the present embodiment has 3 plies or 4 plies. That is, three or four sheets are stacked. By using multiple plies that exceed 2 plies such as 3 plies or 4 plies, the overall paper thickness becomes thick while making each ply thin, making it especially easy to feel "softness" and secure against tearing. It can have a feeling.
なお、2プライであると厚み感が発現し難く、シャワートイレ使用後の多量の水分を吸収しつつ拭き取る際の安心感に欠けるものとなりやすい。また、5プライ以上となると各プライを薄くしても、肌の清拭の際に柔らかさを感じにくくなる。また、後述する本発明に係る1プライ当たりの坪量及び紙厚において5プライ以上として、特にエンボスを付与すると剛性感が強く感じられるようになり、柔らかさが感じられにくいものとなる。 In addition, when it is 2 plies, a feeling of thickness is hard to be developed, and it tends to lack a sense of security when wiping off while absorbing a large amount of water after using the shower toilet. If the number of plies is 5 or more, even if each ply is thinned, it becomes difficult to feel the softness when the skin is wiped. Further, when the basis weight and paper thickness per ply according to the present invention to be described later is 5 plies or more, and particularly embossing is provided, a strong feeling of rigidity is felt and softness is hardly felt.
他方で、本実施形態に係るトイレットペーパーでは、1プライあたり坪量が12.5g/m2以上16.2g/m2以下である。1プライの坪量がこの範囲内であれば上記3又は4プライの際に、十分な破れにくさと肌ざわりの良さとすることができ、また、水解性を発現させやすくなる。 On the other hand, in the toilet paper according to this embodiment, the basis weight per ply is 12.5 g / m 2 or more and 16.2 g / m 2 or less. When the basis weight of one ply is within this range, sufficient tear resistance and good skin feel can be obtained in the case of the above-mentioned three or four plies, and water decomposability can be easily exhibited.
他方、本発明に係るトイレットペーパーは、構成する繊維の80〜100質量%、特に100質量%が酸素蒸解され塩素漂白されていない針葉樹クラフトパルプである。より詳細には、この針葉樹クラフトパルプは、NOKPとも称され、連続蒸解釜にて連続して酸素蒸解をされて製造され、特にその後に塩素系漂白薬品による漂白処理がされていないものである。ここで、トイレットペーパーに用いられるKP(クラフトパルプ)には、漂白されているものと漂白されていないものがあり、未漂白のものはリグニンが多く含まれる。本発明に係る針葉樹クラフトパルプは、塩素系漂白薬品による未漂白であるが酸素蒸解(酸素脱リグニン)が行われているため、リグニンの約半量が除去されている。なお、塩素系漂白薬品は、塩素のみならず、二酸化塩素、次亜塩素酸ソーダも含む意味である。よって、ECFパルプも本発明に係る上記針葉樹クラフトパルプではない。 On the other hand, the toilet paper according to the present invention is a softwood kraft pulp in which 80 to 100% by mass, especially 100% by mass of the constituent fibers is oxygen-digested and is not bleached with chlorine. More specifically, this softwood kraft pulp is also referred to as NOKP, and is produced by continuous oxygen digestion in a continuous digester, and is not particularly bleached with a chlorine bleaching chemical thereafter. Here, KP (kraft pulp) used for toilet paper includes bleached ones and unbleached ones, and unbleached ones contain a large amount of lignin. The softwood kraft pulp according to the present invention has not been bleached with a chlorine-based bleaching chemical, but has undergone oxygen digestion (oxygen delignification), and thus about half of the lignin has been removed. The chlorine-based bleaching chemical is meant to include not only chlorine but also chlorine dioxide and sodium hypochlorite. Therefore, the ECF pulp is not the above-mentioned softwood kraft pulp according to the present invention.
本発明に係るトイレットペーパーでは、塩素系漂白薬品による未漂白であるものの酸素蒸解による脱リグニン処理を行った針葉樹クラフトパルプを80〜100質量%含む。つまり係る針葉樹クラフトパルプを主たる繊維原料、特には全繊維原料として、製造されているため、使用時における人体への安心感があり、かつ、環境に配慮されたものである。なお、特に係る針葉樹クラフトパルプを80〜100質量%含むトイレットペーパーは、薄茶色となり見た目においても化学的な処理がされていない天然物のような印象を受けやすく、また柔らかな印象のものとなるため、購入者は非常に安心感を感ずるものとなる。 The toilet paper according to the present invention contains 80 to 100% by mass of softwood kraft pulp that has not been bleached with a chlorine-based bleaching agent but has been subjected to delignification treatment by oxygen digestion. In other words, since such softwood kraft pulp is manufactured mainly as a fiber raw material, particularly as a whole fiber raw material, it is safe for the human body during use and is environmentally friendly. In particular, the toilet paper containing 80 to 100% by mass of such softwood kraft pulp becomes light brown and tends to have an impression that it is a natural product which has not been chemically treated and has a soft impression. Therefore, the purchaser feels a great sense of security.
一方で、酸素蒸解による脱リグニン処理によってリグニンが酸素蒸解前よりも半分程度にまで低減されているため、脱リグニン処理が全くされていないパルプを原料とするよりも柔らかさが発現させやすいうえ、しっかりとした強度にもしやすい。また、水解性が低くなりやすい広葉樹クラフトパルプが少なくとも20質量%未満、特には0質量%となるため、水解性も良好としやすい。 On the other hand, since the lignin is reduced to about half of that before the oxygen digestion by the delignification treatment by the oxygen digestion, the softness is more likely to be developed than the raw material of the pulp which is not subjected to the delignification treatment. It is easy to make a firm strength. Further, since the content of hardwood kraft pulp, which tends to have low water decomposability, is at least less than 20% by mass, particularly 0% by mass, water decomposability is likely to be good.
また、リグニンは親水性ではないため、これを含む酸素蒸解され塩素漂白されていない針葉樹クラフトパルプは、繊維の膨潤性が低く、繊維間結合が弱くなる。このため、繊維間が疎になり、水解性が良好となる。さらに、針葉樹クラフトパルプは、針葉樹由来のため広葉樹由来のパルプに比して繊維長が長いため、リグニンによる繊維が密にならない作用と相まって、クッション性に優れるものとなる。 In addition, since lignin is not hydrophilic, a softwood kraft pulp that contains oxygen and is not subjected to chlorine bleaching has low swelling property of fibers and weak interfiber bonding. Therefore, the fibers become sparse and the water decomposability becomes good. Furthermore, since the softwood kraft pulp is derived from a softwood and has a longer fiber length than the pulp derived from a hardwood, the lignin provides an excellent cushioning property in combination with the effect of preventing the fibers from becoming dense.
そして、本発明に係るトイレットペーパーは、係る針葉樹クラフトパルプを80〜100質量%含むうえ、1プライの坪量が12.5〜16.0g/m2である。より好ましい1プライの坪量は、12.7〜15.8g/m2である。なお、本発明に係る坪量とは、JIS P 8124(1998)の坪量測定方法によるものである。上記の針葉樹クラフトパルプを80〜100質量%含みつつ、1プライの坪量をやや低い12.5〜15.5g/m2とし、さらに3プライ又は4プライの多プライとすることで、厚み感及び水解性に優れ、柔らかさも発現しやすく、使用時における人体への安心感があり、かつ、環境に配慮されたトイレットパーパーとなる。ここで、本発明に係るトイレットペーパーを構成する他のパルプ繊維は、必ずしも限定されない。バージンパルプでも古紙パルプでもよい。古紙パルプは、古紙からパルプを再生する工程において、再生前のパルプ繊維に比して繊維が細かくなる傾向にあり、このような繊維の性質上、紙厚を厚くせずに、繊維が密となり紙力が高まりやすい。その一方で、過度に配合すると柔軟性などの風合いが低下する。よって古紙パルプの特徴に鑑みて、その配合比率を0〜20質量%未満の範囲で定めればよい。なお、古紙パルプの種類は必ずしも限定されるものではないが、特に、ミルクカートン古紙、上質古紙を原料とする古紙パルプが望ましい。これらは原料由来の広葉樹クラフトパルプ(LBKP)が多く配合されているため、紙力を発現させやすい。 And the toilet paper which concerns on this invention contains 80-100 mass% of such softwood kraft pulp, and the basis weight of 1 ply is 12.5-16.0 g / m < 2 >. The more preferable basis weight of one ply is 12.7 to 15.8 g / m 2 . The grammage according to the present invention is based on the grammage measuring method of JIS P 8124 (1998). While containing 80 to 100% by mass of the above-mentioned softwood kraft pulp, the basis weight of one ply is set to a slightly lower value of 12.5 to 15.5 g / m 2, and further a multi-ply of 3 ply or 4 ply is used to give a feeling of thickness. In addition, it is an excellent water disintegrator, easily develops softness, has a sense of security for the human body during use, and is an environmentally friendly toilet paper. Here, other pulp fibers constituting the toilet paper according to the present invention are not necessarily limited. It may be virgin pulp or waste paper pulp. Waste paper pulp tends to be finer than pulp fibers before it is recycled in the process of recycling pulp from waste paper, and due to the nature of such fibers, the fibers become dense without thickening the paper thickness. Paper strength is easy to increase. On the other hand, if blended excessively, the texture such as flexibility will deteriorate. Therefore, in view of the characteristics of waste paper pulp, the blending ratio may be set in the range of 0 to less than 20% by mass. The type of waste paper pulp is not necessarily limited, but milk carton waste paper and waste paper pulp made from high-quality waste paper are particularly desirable. Since a large amount of hardwood kraft pulp (LBKP) derived from raw materials is mixed in these, it is easy to exert paper strength.
他方、本発明に係るトイレットペーパーは、実質的に保湿剤が塗布されていない保湿剤非塗布のものであるが望ましい。本発明に係る外添剤としての保湿剤は、ポリオール類であり、少なくともグリセリン、ジグリセリン、プロピレングリコール、1,3−ブチレングリコール、ポリエチレングリコールは含まれる。但し、保湿性のトイレットペーパーというに値しない程度にしか影響を与えない程度であれば、上記成分が含有されていることは否定されない。本発明に係るトイレットペーパーは、人体に対する安心感に優れるものであり、保湿剤が塗布されていると保湿剤特有のべたつき感やしっとり感が感じられものとなるため、上記の人体にたいする安心感が低下する。 On the other hand, it is desirable that the toilet paper according to the present invention is substantially a moisturizer-uncoated moisturizer-uncoated one. The humectant as an external additive according to the present invention is a polyol, and at least glycerin, diglycerin, propylene glycol, 1,3-butylene glycol, and polyethylene glycol are included. However, it cannot be denied that the above-mentioned components are contained as long as they do not affect the moisturizing toilet paper. Toilet paper according to the present invention is excellent in a sense of security for the human body, and when a moisturizer is applied, a moisturizer-specific sticky feeling and a moist feeling can be felt, and thus a sense of security for the human body described above. descend.
他方で、本発明に係るトイレットペーパーは、抄紙時に内添する原紙自体の柔らかさや紙力を定める柔軟剤や柔軟保湿剤は添加される。本発明に係るトイレットペーパーに含まれる柔軟剤は、カチオン性脂肪酸アミド系柔軟剤である。本発明に係るトイレットペーパーは、このカチオン性脂肪酸アミド系柔軟剤を含むのがよい。カチオン性脂肪酸アミド系柔軟剤は、リグニン含有による効果の低下がなく、また、繊維表面をコーティングするように作用する。ゆえに、リグニンを含むパルプを高配合しても表面が滑らかで、ごわつき感が顕著に低下し、ふんわり感も高まる。カチオン性脂肪酸アミド系柔軟剤の具体例としては、ポリアルキレンポリアミン類とモノカルボン酸類との反応で得られるアミド系化合物と、エピハロヒドリンとの反応物であるのが望ましい。このカチオン性脂肪酸アミド系柔軟剤であれば効果が発現する。なお、ポリアルキレンポリアミン類とモノカルボン酸類との反応で得られるアミド系化合物と、エピハロヒドリンとの反応物を内添するにあたっては、炭素数が4〜20のアルキル基及び/又はアルケニル基を有する乳化剤、及び水と混合して添加するのがよい。カチオン性脂肪酸アミド系柔軟剤の含有量は必ずしも限定されないが、定着率は50〜60%の場合、製造時における添加量を0.5〜4.0kg/パルプtとすればよい。 On the other hand, the toilet paper according to the present invention is added with a softening agent or a softening agent that determines the softness and paper strength of the base paper itself that is internally added during papermaking. The softener contained in the toilet paper according to the present invention is a cationic fatty acid amide softener. The toilet paper according to the present invention may contain the cationic fatty acid amide-based softener. The cationic fatty acid amide-based softening agent does not reduce the effect due to the inclusion of lignin, and also acts to coat the fiber surface. Therefore, even if the pulp containing lignin is highly blended, the surface is smooth, the rough feeling is significantly reduced, and the fluffy feeling is also increased. A specific example of the cationic fatty acid amide-based softening agent is preferably a reaction product of an epihalohydrin with an amide-based compound obtained by a reaction of polyalkylene polyamines and monocarboxylic acids. With this cationic fatty acid amide type softener, the effect is exhibited. In addition, when internally adding a reaction product of an amide compound obtained by a reaction of polyalkylene polyamines and monocarboxylic acids with epihalohydrin, an emulsifier having an alkyl group and / or an alkenyl group having 4 to 20 carbon atoms , And mixed with water and added. The content of the cationic fatty acid amide-based softening agent is not necessarily limited, but when the fixing rate is 50 to 60%, the addition amount at the time of production may be 0.5 to 4.0 kg / pulp t.
さらに、本発明に係るトイレットペーパーは、柔軟保湿剤が内添されているのが望ましい。その含有量は0.2〜2.0kg/パルプtであるのが望ましい。柔軟保湿剤を含むことで、しなやかさが向上する。特に好ましい柔軟保湿剤は、重量平均分子量500〜10,000のポリアルキレンイミンの活性水素に炭素数2〜4のアルキレンオキサイドを付加させて得られた化合物に、炭素数12〜24の高級脂肪酸および/または炭素数12〜24の高級脂肪酸のエステル化合物を反応させて得られる反応生成物である。この柔軟保湿剤が含まれることで、より柔らかさが向上する。 Furthermore, the toilet paper according to the present invention preferably has a soft moisturizer internally added. The content is preferably 0.2 to 2.0 kg / pulp t. Inclusion of a soft moisturizer improves flexibility. A particularly preferable softening agent is a compound obtained by adding an alkylene oxide having 2 to 4 carbon atoms to active hydrogen of a polyalkyleneimine having a weight average molecular weight of 500 to 10,000, and a higher fatty acid having 12 to 24 carbon atoms and / Or a reaction product obtained by reacting an ester compound of a higher fatty acid having 12 to 24 carbon atoms. By including this soft moisturizer, the softness is further improved.
ここで、本発明に係るトイレットペーパーは、エンボス加工がされていてもよい。そのエンボスパターンは必ずしも限定されるわけではない。エンボスは、マイクロエンボスやドット型のエンボス、デザインエンボス等の適宜のエンボスパターンとすることができる。但し、本発明に係るエンボスパターンは、シングルエンボスと称されるプライ積層状態で付与されるエンボスであるのが望ましい。 Here, the toilet paper according to the present invention may be embossed. The emboss pattern is not necessarily limited. The embossing can be an appropriate embossing pattern such as micro embossing, dot type embossing, design embossing and the like. However, the embossing pattern according to the present invention is preferably an embossing applied in a ply laminated state called a single embossing.
本発明に係る好適なエンボスパターンは、凹部の面積が1.0〜2.5mm2で、密度が5.0〜50個/cm2で、エンボス深さが、0.05〜0.5mmである。トイレットペーパーとしての柔らかさが向上するとともに、トイレットロールのようにロール状態における柔らかさが高まり、消費者が手に持った際に柔らかいと感じやすくなる。特に、図1に示すように、紙面全体に、底面が対角L4×対角L4=1.0〜1.5×1.0〜1.5mmの正方形の凹部31(図1A)又はその正方形の四方角が対角線外方に向かって延在された略正方形(図1B)をなす凹部32が、中心間隔L5が4.5〜5.5mmで幅方向に対する配列角度が45°で格子状に配列され、かつ、凹部31(32)と凹部31(32)との間に凹部の四方角同士から延在する谷線部33を有するものである。なお、谷線部33は、凹部31(32)の四方角が最も深く、凹部間の中間が最も浅くなるように漸次緩やかに断面弓なりに配されているのが望ましい。このエンボスパターンは、柔らかさや便の拭き取り性について優れる。
A preferred embossing pattern according to the present invention has a concave area of 1.0 to 2.5 mm 2 , a density of 5.0 to 50 pieces / cm 2 , and an embossing depth of 0.05 to 0.5 mm. is there. The softness as a toilet paper is improved, and the softness in a roll state like a toilet roll is increased, so that the consumer can easily feel the softness when holding the paper. In particular, as shown in FIG. 1, a square concave portion 31 (FIG. 1A) whose bottom surface is diagonal L4 × diagonal L4 = 1.0 to 1.5 × 1.0 to 1.5 mm, or its square is formed on the entire paper surface. The
エンボスの深さは、株式会社キーエンス社製ワンショット3D測定マクロスコープ VR−3200又はその相当機と、画像解析ソフトウェア「VR−H1A」又はその相当ソフトウェアにより測定する。測定は、倍率12倍、視野面積24mm×18mmの条件で測定する。但し、倍率と視野面積は、エンボス(凹部)の大きさによって、適宜変更することができる。具体的な測定手順は、図2を参照して説明すると、上記ソフトウェアを用いて、平面視点で示される画像部(図中X部分)中の一つのエンボス(凹部)40の周縁の最長部を横切る線分Q1におけるエンボス深さ(測定断面曲線)プロファイルを得る。このエンボス深さプロファイルの断面曲線からλc:800μm(但し、λcはJIS−B0601「3.1.1.2」に記載の「粗さ成分とうねり成分との境界を定義するフィルタ」)より短波長の表面粗さの成分を低域フィルタによって除去して得られる断面視点で示される画像部(図中Y部分)の「輪郭曲線Q2」のうち、上に凸で最も曲がりが強くなる2つの凹部エッジ点P1,P2と、凹部エッジ点P1,P2で挟まれる最小値を求め、深さの最小値Minとする。さらに、凹部エッジ点P1,P2の深さの値の平均値を深さの最大値Maxとする。このようにして、エンボス深さ=最大値Max−最小値Minとする。又、凹部エッジ点P1,P2のX−Y平面上の距離(長さ)を最長部の長さと規定する。上記の上に凸で最も曲がりが強くなる2つの凹部エッジ点P1,P2は目視にて選択する。なお、その選択にあたっては、当該測定中のエンボス(凹部)40の平面視点の画像中の輪郭Eを参考としてもよい。同様にして、最長部に垂直な方向での最短部についてもエンボス(凹部)の深さを測定し、大きい方の値をエンボス(凹部)の深さとして採用する。以上の測定を、トイレットペーパー表面の任意の10個のエンボスについて行い、その平均値を最終的なエンボス深さとする。 The depth of embossing is measured by a one-shot 3D measurement macroscope VR-3200 manufactured by Keyence Corporation or its equivalent machine and image analysis software "VR-H1A" or its equivalent software. The measurement is performed under the conditions of a magnification of 12 times and a visual field area of 24 mm × 18 mm. However, the magnification and the field of view can be appropriately changed depending on the size of the emboss (recess). A specific measurement procedure will be described with reference to FIG. 2. Using the software described above, the longest part of the peripheral edge of one emboss (recess) 40 in the image part (X part in the drawing) shown in a plan view is determined. An embossing depth (measurement cross section curve) profile at a crossing line segment Q1 is obtained. From the cross-section curve of this embossing depth profile, shorter than λc: 800 μm (where λc is the “filter that defines the boundary between the roughness component and the waviness component” described in JIS-B0601 “3.1.1.2”). Of the "contour curve Q2" of the image portion (Y portion in the figure) shown by the cross-sectional viewpoint obtained by removing the component of the wavelength surface roughness by the low-pass filter, the two curves that are convex upward and have the strongest bending The minimum value sandwiched between the recess edge points P1 and P2 and the recess edge points P1 and P2 is determined and set as the minimum depth value Min. Further, the average value of the depth values of the recess edge points P1 and P2 is set as the maximum depth value Max. In this way, emboss depth = maximum value Max−minimum value Min. Further, the distance (length) of the recess edge points P1 and P2 on the XY plane is defined as the length of the longest portion. The two concave edge points P1 and P2 that are convex upward and have the strongest bending are visually selected. In the selection, the contour E in the plane view image of the embossing (recess) 40 during the measurement may be referred to. Similarly, the depth of the embossing (recess) is measured also for the shortest part in the direction perpendicular to the longest part, and the larger value is adopted as the depth of the embossing (recess). The above measurement is performed for any 10 embosses on the surface of the toilet paper, and the average value thereof is used as the final emboss depth.
なお、エンボスパターンの個々の凹部の面積についても、ワンショット3D測定マクロスコープ VR−3200又はその相当機と、画像解析ソフトウェア「VR−H1A」又はその相当ソフトウェアにより測定して得た3D画像から目視でエンボス凹部の輪郭を確認し、輪郭内部の面積を測定する。トイレットペーパー表面の任意の10個のエンボスについて行い、その平均値を最終的なエンボス凹部の面積とする。 In addition, the area of each concave portion of the embossed pattern is also visually observed from a 3D image obtained by measuring with the one-shot 3D measurement macroscope VR-3200 or its equivalent machine and the image analysis software "VR-H1A" or its equivalent software. Check the contour of the embossed recess and measure the area inside the contour. The process is performed for any 10 embosses on the surface of the toilet paper, and the average value is used as the final embossed recess area.
他方で、本発明に係るトイレットペーパーは、1プライの紙厚が120〜150μmであり、トイレットペーパー全体としての紙厚が400〜600μmである。紙厚をこの範囲とすることで柔らかさが向上されたものとなる。トイレットペーパーの紙厚の測定方法は、試験片をJIS P 8111(1998)の条件下で十分に(通常は、8時間程度)調湿した後、同条件下でダイヤルシックネスゲージ(厚み測定器)「PEACOCK G型」(尾崎製作所製)を用いて1プライの状態で測定するものとする。具体的には、プランジャーと測定台の間にゴミ、チリ等がないことを確認してプランジャーを測定台の上におろし、前記ダイヤルシックネスゲージのメモリを移動させてゼロ点を合わせ、次いで、プランジャーを上げて試料を試験台の上におき、プランジャーをゆっくりと下ろしそのときのゲージを読み取る。トイレットペーパーがエンボス加工されている場合には、構成する一つの凹部(凸部)が必ず測定台の範囲に入るようにする。なお、深さの異なる凹部が存在する場合には、最も深さの深い凹部が位置するようにする。この測定時には、プランジャーはのせるだけとして押えない。プランジャーの端子は金属製で直径10mmの円形の平面が紙平面に対し垂直に当たるようにし、この紙厚測定時の荷重は、約70gfである。なお、紙厚は測定を10回行って得られる平均値とする。ここで、紙厚の測定時には、エンボス(凹部)の潰れが想定されるが、本発明に係る紙厚は、そのような潰れも含んで測定した値であり、そのような潰れは無視してよい。本紙厚測定において凹部の潰れによって生ずる紙厚差は無視できる。
On the other hand, in the toilet paper according to the present invention, the paper thickness of one ply is 120 to 150 μm, and the paper thickness of the entire toilet paper is 400 to 600 μm. By setting the paper thickness within this range, the softness is improved. To measure the thickness of toilet paper, the test piece should be conditioned under JIS P 8111 (1998) sufficiently (usually for about 8 hours), and then dial thickness gauge (thickness measuring instrument) under the same conditions. It is to be measured in a 1-ply state using "PEACOCK G type" (manufactured by Ozaki Seisakusho). Specifically, check that there is no dust or dust between the plunger and the measuring table, lower the plunger on the measuring table, move the memory of the dial thickness gauge to set the zero point, and then , Raise the plunger and place the sample on the test bench, slowly lower the plunger and read the gauge at that time. If the toilet paper is embossed, make sure that one of the concave parts (convex parts) is within the range of the measuring table. When there are recesses having different depths, the recess having the deepest depth is located. During this measurement, the plunger is only placed and cannot be pressed. The terminal of the plunger is made of metal so that a circular plane having a diameter of 10 mm hits the plane of the paper perpendicularly, and the load when measuring the paper thickness is about 70 gf. The paper thickness is an average value obtained by performing the
また、本発明に係るトイレットペーパーは、水解性が10秒以内であり、非常に速い。これは、構成繊維の80質量%以上、特に100質量%がリグニンを含む針葉樹クラフトパルプであり、繊維がほぐれやすくなっているためである。水解性が10秒以内であれば、水洗トイレ等に流水廃棄した際に配管を詰まらせるおそれが各段に小さくなる。この水解性(ほぐれやすさ)の測定は、JIS P 4501(1993)による。ほぐれやすさの試験は、水300mL(水温20±5℃)を入れた300mLのビーカーをマグネチックスターラーに載せ、回転子の回転数を600±10回転/分になるように調整する。その中に一辺が100±2mm角の試験片を投入し、ストップウォッチを押す。回転子の回転数は試験片の抵抗によって、いったん約500回転に下降し、試験片がほぐれるに従い回転数は上昇する。この回転数が540回転までに回復した時点でストップウォッチを止め、その時間を1秒単位で測定する。ほぐれやすさの結果は、試験を5回行い、その平均で表す。回転子は、直径35mm、厚さ12mmの円盤状のものとする。
Further, the toilet paper according to the present invention has a water degradability of 10 seconds or less, which is very fast. This is because 80% by mass or more, especially 100% by mass of the constituent fibers are softwood kraft pulp containing lignin, and the fibers are easily disentangled. If the water disintegration is within 10 seconds, the risk of clogging the pipe when flushing the water away from the flush toilet or the like is further reduced. The measurement of this water decomposability (easiness of loosening) is according to JIS P 4501 (1993). For the test of easiness of loosening, a 300 mL beaker containing 300 mL of water (
本発明に係るトイレットペーパーは、抄紙原料のカナダ標準濾水度が、650cc以上であるのが望ましい。抄紙原料のカナダ濾水度が650cc以上とは、ほとんどパルプ繊維が叩解されていないか、未叩解原料である繊維であるため、水解性により優れるものとしやすい。 The toilet paper according to the present invention preferably has a Canadian standard freeness of 650 cc or more as a papermaking raw material. When the Canadian freeness of the papermaking raw material is 650 cc or more, almost no pulp fibers are beaten or fibers which are unbeaten raw materials, so that it is likely to be more excellent in water degradability.

The lateral direction of the paper is also called the CD direction and is a direction orthogonal to the flow direction (MD direction) at the time of papermaking. The dry tensile strength according to the present invention is a value measured based on JIS P 8113 (2006), and is measured as follows. A test piece cut into a width of 25 mm (± 0.5 mm) and a length of 150 mm is used in both the vertical and horizontal directions. The test piece is measured in multiple plies. As the tester, a load cell tensile tester TG-200N manufactured by Minebea Co., Ltd. and an equivalent machine corresponding thereto are used. The gripping interval is set to 100 mm and the pulling speed is set to 100 mm / min. The measurement is performed by tightening both ends of the test piece to the grip of the tester, applying a tensile load to the paper piece in the vertical direction, and reading the indicated value (digital value) when the paper breaks. Five sets of samples are prepared for each of the vertical direction and the horizontal direction, and each set is measured 5 times, and the average of the measured values is taken as the dry tensile strength in each direction. According to the number of plies of the product, a plurality of products were superposed and the dry tensile strength was measured. As for the base paper, the dry tensile strength was measured by stacking a plurality of sheets according to the number of plies of the product.
また、本発明に係るトイレットペーパーは、縦方向の湿潤引張強度が50cN/25mm以上100cN/25mm以下、であるのが望ましい。横方向の湿潤引張強度は25cN/25mm以上50cN/25mm以下、であるのが望ましい。湿潤引張強度は、JIS P 8135(1998)に基づいて測定した値であり、次のようにして測定する。試験片は縦・横方向ともに巾25mm(±0.5mm)×長さ150mm程度に裁断したものを用いる。ティシュペーパーは複数プライの場合は複数プライのまま測定する。試験機は、ミネベア株式会社製ロードセル引張り試験機TG−200N及びこれに相当する相当機を用いる。なお、つかみ間隔100mm、引張速度は50mm/minに設定する。試験片は、105℃の乾燥機で10分間のキュアリングを行ったものを用いる。試験片の両端を試験機のつかみに締め付けた後、水を含ませた平筆を用い、試験片の中央部に約10mm幅で水平に水を付与し、その後、直ちに紙片に対して上下方向に引張り荷重をかけ、紙が破断する時の指示値(デジタル値)を読み取る手順で測定を行う。縦方向、横方向ともに各々5組の試料を用意して各5回ずつ測定し、その測定値の平均を各方向の湿潤引張強度とする。湿潤引張強度においても製品のプライ数に合わせて、複数枚重ねて湿潤引張強度を測定した。 Further, the toilet paper according to the present invention preferably has a wet tensile strength in the longitudinal direction of 50 cN / 25 mm or more and 100 cN / 25 mm or less. The wet tensile strength in the transverse direction is preferably 25 cN / 25 mm or more and 50 cN / 25 mm or less. The wet tensile strength is a value measured based on JIS P 8135 (1998), and is measured as follows. A test piece cut into a width of 25 mm (± 0.5 mm) and a length of 150 mm is used in both the vertical and horizontal directions. If the tissue paper has multiple plies, measure it as it is. As the tester, a load cell tensile tester TG-200N manufactured by Minebea Co., Ltd. and an equivalent machine corresponding thereto are used. The gripping interval is set to 100 mm and the pulling speed is set to 50 mm / min. As the test piece, a test piece that has been cured by a dryer at 105 ° C. for 10 minutes is used. After tightening both ends of the test piece to the grips of the tester, use a flat brush soaked in water to apply water horizontally with a width of about 10 mm to the center of the test piece, and then immediately move it vertically with respect to the paper piece. A tensile load is applied to and the measurement is performed by reading the indicated value (digital value) when the paper breaks. Five sets of samples are prepared in each of the vertical direction and the horizontal direction, and each set is measured 5 times, and the average of the measured values is taken as the wet tensile strength in each direction. Also in terms of wet tensile strength, the wet tensile strength was measured by stacking a plurality of sheets in accordance with the number of plies of the product.
本発明に係るトイレットペーパーは、表面性を示す指標であるMMDの値が7.5以上9.5以下であることが望ましい。MMDが7.5未満であると表面が滑り過ぎて拭き取り性が低下し、9.5超であると肌触りが悪くトイレットペーパーとしての用途に適さないおそれがある。なお、MMDの測定は、摩擦子の接触面を所定方向に20g/cmの張力が付与された測定試料の表面に対して25gの接触圧で接触させながら、張力が付与された方向と略同じ方向に速度0.1cm/sで2cm移動させ、このときの、摩擦係数を、摩擦感テスター KES−SE(カトーテック株式会社製)又はその相当機を用いて測定する。その摩擦係数を摩擦距離(移動距離=2cm)で除した値がMMDである。摩擦子は、直径0.5mmのピアノ線Pを20本隣接させてなり、長さ及び幅がともに10mmとなるように形成された接触面を有するものとする。接触面には、先端が20本のピアノ線P(曲率半径0.25mm)で形成された単位膨出部が形成されているものとする。 In the toilet paper according to the present invention, it is desirable that the value of MMD, which is an index showing the surface property, is 7.5 or more and 9.5 or less. If the MMD is less than 7.5, the surface will be too slippery and the wiping property will be deteriorated, and if it is more than 9.5, the touch will be poor and it may not be suitable for use as toilet paper. The measurement of the MMD is substantially the same as the direction in which the tension is applied while the contact surface of the friction element is brought into contact with the surface of the measurement sample to which the tension of 20 g / cm is applied in the predetermined direction with a contact pressure of 25 g. In the direction at a velocity of 0.1 cm / s for 2 cm, and the friction coefficient at this time is measured using a friction feeling tester KES-SE (manufactured by Kato Tech Co., Ltd.) or its equivalent machine. The value obtained by dividing the friction coefficient by the friction distance (moving distance = 2 cm) is MMD. The friction element is made up of 20 piano wires P having a diameter of 0.5 mm adjacent to each other, and has a contact surface formed so that both length and width are 10 mm. It is assumed that the contact surface is formed with a unit bulge portion having a tip of 20 piano wires P (curvature radius 0.25 mm).
本実施形態のトイレットペーパーは、ソフトネスは、1.8cN/100mm以上3.5cN/100mm以下であるのが望ましい。ソフトネスは、その値が低いほど柔らかいとされる柔らかさの指標の一つである。ティシュペーパーやトイレットペーパーであれば、1.0cN/100mm以下であれば十分に柔らかいとされる。ソフトネスの測定は、JIS L 1096 E法(1990)に準じたハンドルオメータ法に基づいて測定した値をいう。但し、試験片は100mm×100mmの大きさとし、クリアランスは5mmとする。1プライで縦方向、横方向の各々5回ずつ測定し、その全10回の平均値とする、なお、ソフトネスは、無単位であるが、試験片の大きさを考慮して、cN/100mmを単位として表されることもある。 The softness of the toilet paper of this embodiment is preferably 1.8 cN / 100 mm or more and 3.5 cN / 100 mm or less. Softness is one of the indices of softness that the lower the value, the softer it is. For tissue paper or toilet paper, 1.0 cN / 100 mm or less is considered to be sufficiently soft. The softness is a value measured based on the handle odometer method according to JIS L 1096 E method (1990). However, the test piece has a size of 100 mm × 100 mm, and the clearance is 5 mm. Each ply is measured 5 times in the longitudinal direction and 5 times in the lateral direction, and the average value of all 10 times is taken. The softness is unitless, but cN / It may be expressed in units of 100 mm.
本実施形態のトイレットペーパーにおいては、乾燥引張強度及び湿潤引張強度の調整は、乾燥紙力増強剤や湿潤紙力増強剤の紙力剤を用いることなく調整することができる。そして、特に、使用者の安心感の点から紙力剤を含まないのが望ましい。本発明に係るトイレットペーパーでは、紙力剤を含まなくとも繊維長の長い針葉樹クラフトパルプを80質量%以上、特に100質量%含むように高配合することで、繊維間の絡みが確保され、使用に十分な強度とすることができる。そのうえで、リグニンを含むものであるため水解性にも優れる。つまり、紙力剤を用いなくとも十分な強度が確保でき、さらに水解性にも優れるようにできる。 In the toilet paper of this embodiment, the dry tensile strength and the wet tensile strength can be adjusted without using a paper strength agent such as a dry paper strength enhancer or a wet paper strength enhancer. In particular, it is desirable not to include a paper strength agent from the viewpoint of the user's sense of security. In the toilet paper according to the present invention, even if it does not contain a paper-strengthening agent, a high content of 80% by mass or more, especially 100% by mass of a softwood kraft pulp having a long fiber length ensures a entanglement between fibers, and it is used. Can have sufficient strength. In addition, since it contains lignin, it is also excellent in water decomposability. That is, it is possible to secure sufficient strength without using a paper-strengthening agent, and also to improve water decomposability.
なお、本実施形態のトイレットペーパーにおいては、上記のとおり乾燥紙力増強剤や湿潤紙力増強剤を用いないのが望ましいが、水解性を阻害しない範囲で、必要に応じて用いてもよい。ここでいう乾燥紙力増強剤は、澱粉、ポリアクリルアミド、CMC(カルボキシメチルセルロース)若しくはその塩であるカルボキシメチルセルロースナトリウム、カルボキシメチルセルロースカルシウム、カルボキシメチルセルロース亜鉛が挙げられる。 In the toilet paper of the present embodiment, it is desirable not to use a dry paper strength enhancer or a wet paper strength enhancer as described above, but it may be used if necessary as long as it does not impair water decomposability. Examples of the dry paper strength enhancer used herein include starch, polyacrylamide, CMC (carboxymethyl cellulose) or its salt, carboxymethyl cellulose sodium, carboxymethyl cellulose calcium, and carboxymethyl cellulose zinc.
湿潤紙力増強剤は、ポリアミドポリアミンエピクロルヒドリン樹脂、尿素樹脂、酸コロイド・メラミン樹脂、熱架橋性塗工PAM、星光PMC株式会社社製のTS−20、グリオキシル化ポリアクリルアミド、カチオン性グリオキシル化ポリアクリルアミドなどのポリマーアルデヒド−官能性化合物、グリオキザールの二価のアルデヒドで変性したアクリルアミドモノマーと他の共重合可能な不飽和モノマーの共重合体又はジアルデヒド澱粉が挙げられる。 The wet paper strengthening agent is polyamide polyamine epichlorohydrin resin, urea resin, acid colloid / melamine resin, thermally crosslinkable coating PAM, TS-20 manufactured by Seikou PMC Co., glyoxylated polyacrylamide, cationic glyoxylated polyacrylamide. Polymeric aldehyde-functional compounds such as, copolymers of acrylamide monomers modified with glyoxal divalent aldehydes and other copolymerizable unsaturated monomers, or dialdehyde starch.
他方、本実施形態のトイレットペーパーは、図3に示されるように、帯状のトイレットペーパー10を紙管(管芯とも称される)20にロール状に巻いたトイレットロールの形態とするに適する。
On the other hand, as shown in FIG. 3, the toilet paper of the present embodiment is suitable for the form of a toilet roll in which a strip-shaped
この本発明に係るトイレットロールは、巻径L2(直径)110〜115mmであるのが望ましい。トイレットロールの巻径は、JIS P 4501において、120mm以下と定められており、一般的なトイレットロールをセットするためのホルダーはこの120mmを基準として作成されている。本発明のトイレットロールは、巻径が110〜115mmであり、一般的なホルダーに十分にセット可能な大きさとなっている。ここで、巻径は、ムラテックKDS株式会社製ダイヤメータールール又はその相当機を用いて測定した値である。測定値は、幅方向に場所を変えて3個所測定した平均値とする。なお、同一製造ロット品における平均値は5個のロールの平均値とする。 The toilet roll according to the present invention preferably has a winding diameter L2 (diameter) of 110 to 115 mm. The roll diameter of the toilet roll is specified in JIS P 4501 to be 120 mm or less, and a holder for setting a general toilet roll is made based on this 120 mm. The toilet roll of the present invention has a winding diameter of 110 to 115 mm, and has a size that can be sufficiently set in a general holder. Here, the winding diameter is a value measured using a Diameter rule manufactured by Muratec KDS Co., Ltd. or an equivalent machine. The measured value is an average value measured at three locations by changing the location in the width direction. The average value of the same production lot product is the average value of 5 rolls.
一方、係るトイレットロールは、巻き長さが20〜40mであるのが望ましく、その際、巻密度を0.20〜0.30m/cm2とするのが望ましい。ここでの巻密度とは、巻長さ(m)÷実断面積で算出される値である。実断面積とは、{(巻径/2)×(巻径/2)×π−(紙管外径/2)×(紙管外径/2)×π}(単位;cm2)で算出される値である。つまり、端面の面積から紙管開口端側面積を差し引いた面積である。本発明に係るトイレットペーパーは、上記のロール形態において、その巻き密度が0.20〜0.28m/cm2の範囲にあるとロールを周面で手に持った際に顕著に柔らかさを感じるものとなる。なお、紙管外径(紙管径)L3は、一般的な大きさと同様に35〜45mmφとするのが望ましい。 On the other hand, such a toilet roll preferably has a winding length of 20 to 40 m and, at that time, a winding density of 0.20 to 0.30 m / cm 2 . The winding density here is a value calculated by winding length (m) / actual cross-sectional area. The actual cross-sectional area is {(roll diameter / 2) × (roll diameter / 2) × π− (paper tube outer diameter / 2) × (paper tube outer diameter / 2) × π} (unit: cm 2 ). It is a calculated value. That is, it is the area obtained by subtracting the area on the opening side of the paper tube from the area of the end surface. The toilet paper according to the present invention, in the roll form described above, when the winding density is in the range of 0.20 to 0.28 m / cm 2 , the roll feels remarkably soft when held by the hand on the peripheral surface. Will be things. The outer diameter (paper tube diameter) L3 of the paper tube is preferably 35 to 45 mmφ, which is the same as a general size.
また、本発明のトイレットペーパーは、ロールの巻き固さが、1.8〜2.2mmであるのが望ましい。ロールの巻き固さ(mm)(T0−TM)の測定には、カトーテック株式会社製「ハンディー圧縮試験機 KES−G5」を用いる。鋼板で形成された水平な台座上にトイレットロールTRをその中心軸が水平になるように横置きし、ロール胴部外周の上面中心に圧縮面積2cm2の円形平面をもつ鋼板端子を当接させ、この当接した状態をゼロ点として、かかるゼロ点から前記鋼板端子を鉛直下方に速度10mm/分で移動させてトイレットロールを圧縮する。圧縮荷重0.5gf/cm2のときの押しみ量をT0(mm)、圧縮荷重を50gf/cm2のときの押しみ量をTM(mm)として、(T0−TM)(mm)をロールの巻き固さ(mm)とする。ロールの巻き固さ(mm)が大きいほど、50gf/cm2まで押し込んだ時の押し込み深さが大きく、ふんわりとした紙質であることを示す。すなわち、ふんわり感に対応する。なお、上記巻き長さ及び巻き密度であれば、十分に係る巻き固さにできる。 Further, in the toilet paper of the present invention, it is desirable that the roll winding hardness is 1.8 to 2.2 mm. To measure the roll hardness (mm) (T0-TM), "Handy compression tester KES-G5" manufactured by Kato Tech Co., Ltd. is used. Toilet roll TR is placed horizontally on a horizontal pedestal made of steel plate so that its central axis is horizontal, and a steel plate terminal having a circular flat surface with a compression area of 2 cm 2 is brought into contact with the center of the upper surface of the outer periphery of the roll body. With this contact state as a zero point, the steel plate terminal is moved vertically downward from the zero point at a speed of 10 mm / min to compress the toilet roll. The pressing amount when the compressive load is 0.5 gf / cm 2 is T0 (mm), the pressing amount when the compressive load is 50 gf / cm 2 is TM (mm), and (T0-TM) (mm) is the roll Roll hardness (mm). The greater the winding hardness (mm) of the roll, the greater the depth of indentation when pressed up to 50 gf / cm 2, indicating that the paper quality is fluffy. That is, it corresponds to a soft feeling. In addition, if it is the said winding length and winding density, it can be set to the sufficient winding hardness.
さらに、本発明のトイレットロールは、圧縮仕事量(WC)が、3.6〜4.6gf・cm/cm2であるのが望ましい。圧縮仕事量(WC)は、ロールに鋼板端子を0.5gf/cm2で接してから50gf/cm2まで押し込んだ際の仕事量であり、圧縮仕事量(WC)が大きいほど、押し込み初期の反発力が弱いためロールを掴んだ瞬間に柔らかく感じ、その後、圧縮荷重を通常ロールを掴むときの50gf/cm2まで深く押し込むと、ロールが柔らかく、ふんわりし品質であると評価できる。 Furthermore, the toilet roll of the present invention preferably has a compression work (WC) of 3.6 to 4.6 gf · cm / cm 2 . Compression work amount (WC) is an amount of work when pushed to 50 gf / cm 2 from contact with steel pins to roll 0.5 gf / cm 2, as the amount of compression work (WC) is large, the initial pushing Since the repulsive force is weak, it feels soft at the moment of gripping the roll, and when the compression load is then pushed deeply to 50 gf / cm 2 when gripping the roll, it can be evaluated as soft and fluffy quality.
本発明に係るトイレットペーパーは、繊維の80〜100質量%が酸素蒸解され塩素漂白されていないリグニンを含む繊維長の長い針葉樹クラフトパルプであり、繊維間同士の結合が弱いため、上記のロール形態とした際に、クッション性に優れ手に持ったさいに上記のとおり柔らかさを感じやすい。 The toilet paper according to the present invention is a long-fiber softwood kraft pulp containing lignin in which 80 to 100% by mass of the fiber has been digested with oxygen and has not been bleached with chlorine, and the bond between the fibers is weak, so that the above roll form is used. In that case, the cushioning property is excellent and the softness is easily felt as described above when held in the hand.
以下、実施例を参照しながらさらに本発明にかかるトイレットペーパーの効果について説明する。 Hereinafter, the effects of the toilet paper according to the present invention will be further described with reference to examples.
次いで、本発明のトイレットペーパーの実施例及び比較例について「柔らかさ」、「ふんわり感」、「厚み感」、「使用時の破れ、強さ」について官能評価を行った。 Next, sensory evaluations were performed on the examples of the toilet paper of the present invention and the comparative examples with respect to "softness", "softness", "thickness", "tear during use, strength".

With respect to each item, relative evaluation was performed based on Comparative Example 3 (conventional product). The evaluation was made by setting Comparative Example 3 to 4 points (median value), scoring up to 7 points when it was good and 1 point when it was bad, scoring with a difference for each point, and calculating the average value to determine It was decided to.
本発明に係る実施例は、官能評価において優れた結果となった。また、水解性については、各段に優れた結果となった。また、巻き密度がほぼ同様の比較例1と比べても、ロールにした際における巻き固さ及び圧縮仕事量(WC)において優位な測定結果が得られた。さらに、強度についても使用時の破れのない十分な強度が確保されている測定結果が得られた。 The examples according to the present invention gave excellent results in sensory evaluation. Moreover, regarding the water decomposability, excellent results were obtained. Further, even when compared with Comparative Example 1 in which the winding densities are almost the same, superior measurement results were obtained in the winding hardness and the compression work (WC) when formed into a roll. Further, as for the strength, a measurement result was obtained in which sufficient strength was secured without breakage during use.
このように、本発明に係るトイレットペーパーは、シャワートイレで使用するような場面において安心できる厚み感があり、柔らかさが十分で、さらに水解性に優れ、使用時における人体への安心感があるものである。 As described above, the toilet paper according to the present invention has a thickness feeling that can be relieved when used in a shower toilet, has sufficient softness, is excellent in water disintegration, and has a sense of security for the human body during use.
