Description

トイレットペーパーロールToilet paper roll
　この発明は、ローション等の保湿成分や、柔軟成分を塗工したトイレットペーパーロールに関する。 The present invention relates to a toilet paper roll coated with a moisturizing component such as a lotion and a soft component.
　近年、ローション等の保湿成分を塗工したティッシュペーパーやトイレットペーパーが開発されている（特許文献１～３参照）。例えばローションティッシュは、かぜや花粉症等による鼻炎発症時に肌に優しい成分や炎症を緩和する成分が塗工され、これらローション成分はグリセリンやソルビトールを主成分とする水溶性保湿成分と、ウェッブに滑らかさを付与する界面活性剤、さらに必要に応じてアロエ等の薬効成分が調合されている。これら成分はいずれも水溶性であるか、又はエマルションなどで水溶性化処理されている。 In recent years, tissue paper and toilet paper coated with a moisturizing component such as lotion have been developed (see Patent Documents 1 to 3). For example, lotion tissue is coated with skin-friendly components and components for relieving inflammation at the onset of rhinitis due to cold and hay fever etc. These lotion components are smooth with a water-soluble moisturizing component consisting mainly of glycerin and sorbitol, and web. Surfactants for imparting hardness and, if necessary, medicinal ingredients such as aloe are prepared. All of these components are water-soluble or are water-solubilized by an emulsion or the like.

　ところで、ティッシュペーパーには湿潤紙力増強剤が添加されており、強度が比較的高いため、塗工時に水溶性のローション成分に接触しても原紙が断紙せずに塗工可能である。しかしながら、水解性が要求されるトイレットペーパーには湿潤紙力剤が添加できないことから、水溶性のローション成分をトイレットペーパーの全面に塗工すると原紙が破れてしまい、塗工ができなくなるという問題がある。 By the way, since a wet strength agent is added to the tissue paper and the strength is relatively high, the base paper can be coated without being broken even if it contacts a water-soluble lotion component at the time of coating. However, since the wet paper strengthening agent can not be added to the toilet paper that requires water degradability, if the water-soluble lotion component is applied to the entire surface of the toilet paper, the base paper may be broken and the coating can not be performed. is there.
　従って本発明は、全面に水溶性保湿成分及び／又は柔軟成分を塗工することが可能なトイレットペーパーロールの提供を目的とする。 Therefore, an object of the present invention is to provide a toilet paper roll which can be coated with a water-soluble moisturizing component and / or a soft component on the entire surface.
　上記課題を解決するため、本発明のトイレットペーパーロールは、JIS-P4501に示すほぐれ易さが１００秒以下のトイレットペーパーロールであって、シートの少なくとも片面の全面に、水溶性保湿成分及び/又は柔軟成分が塗工されている。 In order to solve the above-mentioned subject, a toilet paper roll of the present invention is a toilet paper roll whose ease of loosening shown in JIS-P4501 is 100 seconds or less, and it is a water-soluble moisturizing ingredient and / or all over at least one side of a sheet. The soft component is coated.

The water-soluble moisturizing component and / or the pliable component are separated at intervals of 2 mm to 10 mm in a direction substantially perpendicular to the winding direction on at least one side of the base paper of the sheet before winding the toilet paper roll. However, it is preferable to apply a liquid containing the water-soluble moisturizing component and / or the flexible component to provide a plurality of coating regions, and to set the coating width of the coating region to 1 mm to 10 mm.
　前記水溶性保湿成分は、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、又はポリエチレングリコールの多価アルコール類；ソルビトール、グルコース、キシリトール、マルトース、マルチトールの多糖類；及びセタノール、ステアリルアルコール、又はオレイルアルコールの高級アルコールの水溶性化誘導体又は乳化物；の群から選ばれる１種以上（Ａ）であり、前記柔軟成分は、アミノ変性シリコーン、親水性ポリエーテル変性シリコーンのポリシロキサン系柔軟剤；ポリエチレングリコール脂肪酸エーテル、ポリエチレンエーテル、多価アルコール脂肪酸エステルの非イオン型界面活性剤；４級アンモニア塩型又はアミン塩型カチオン型界面活性剤；両性型界面活性剤、及びアニオン型界面活性剤の群から選ばれる１種以上（Ｂ）であり、（Ａ）：（Ｂ）の質量比率が９９．５：０．５～８０：２０であることが好ましい。 The water-soluble moisturizing component is glycerin, diglycerin, propylene glycol, 1,3-butylene glycol, or polyhydric alcohols of polyethylene glycol; sorbitol, glucose, xylitol, maltose, maltitol polysaccharides; and cetanol, stearyl alcohol Or at least one member (A) selected from the group of water-solubilized derivatives or emulsions of higher alcohols of oleyl alcohol; the soft component is an amino-modified silicone, a polysiloxane-based soft of a hydrophilic polyether-modified silicone Agents; nonionic surfactants of polyethylene glycol fatty acid ether, polyethylene ether, polyhydric alcohol fatty acid ester; quaternary ammonia salt type or amine salt type cationic surfactant; amphoteric surfactant, and anionic type surfactant Group of It is preferable that it is one or more types selected from (B), and the mass ratio of (A) :( B) is 99.5: 0.5 to 80:20.

　以下、本発明の実施形態に係るトイレットペーパーロールについて説明する。
　本発明の実施形態に係るトイレットペーパーロールは、JIS-P4501に示すほぐれ易さが１００秒以下である。ほぐれ易さが１００秒を超えると、水に溶解し難くなってトイレットペーパーとして使用できなくなる。水洗流量のバラツキを考慮すると、ほぐれ易さは５０秒以下がより好ましい。又、トイレットペーパーは、水分に接触すると瞬時に繊維間の水素結合が破壊されて強度を失って水解するよう、湿潤紙力剤を含まないことが好ましい。
　トイレットペーパーロールの原紙としては、パルプ100％又は、パルプと古紙の混合物を用いるとよい。パルプと古紙を混合すると、古紙による風合い低下が生じるが本発明ではこれを改善する効果が期待できる。シートは一枚でもよいが、複数枚重ねるとよい。原紙（シート）の合計坪量（１枚、又は複数枚重ねた場合はその合計）は好ましくは１５～４５ｇ/ｍ2である。 Hereinafter, the toilet paper roll concerning the embodiment of the present invention is explained.
In the toilet paper roll according to the embodiment of the present invention, the ease of loosening shown in JIS-P4501 is 100 seconds or less. When the ease of loosening exceeds 100 seconds, it becomes difficult to dissolve in water and can not be used as a toilet paper. In consideration of the variation in the flush flow rate, the ease of loosening is more preferably 50 seconds or less. In addition, it is preferable that the toilet paper does not contain a wet paper strengthening agent so that when it comes into contact with moisture, hydrogen bonds between fibers are instantly broken to lose strength and hydrolyze.
As the base paper of the toilet paper roll, it is preferable to use 100% pulp or a mixture of pulp and waste paper. When pulp and waste paper are mixed, texture deterioration due to waste paper occurs, but in the present invention, the effect of improving this can be expected. Although one sheet may be used, it is preferable to stack a plurality of sheets. The total basis weight of the base paper (sheet) (the sum of one or more sheets) is preferably 15 to 45 g / m 2 .
　また、原紙の吸水性は、水溶性保湿成分及び/又は柔軟成分の塗工スピード及び塗工均一性に影響を与えるため、吸水性に優れた原紙が好ましい。例えば、0.1ｍｌ滴下法による、原紙の吸水速度が５秒以下であることが好ましく、より好ましくは１秒以下である。ここで、0.1ｍｌ滴下法は、温度20±１℃の蒸留水0.1ｍｌを、約10ｍｍの高さから原紙に滴下して、水滴が紙面に接触したときから、完全に吸収されて反射光が消えるまでの時間をいう。又、原紙の吸水速度は、原料配合物及びエンボス等による表面処理等の影響を受け、原料に古紙が含まれると吸水性が低下することが一般に知られている。従って、塗工前の原紙にエンボス加工を施すと、吸水性が向上するので好ましい。
　又、塗工後にエンボスを施す場合、湿潤状態でエンボスが施されるために、エンボス部に塗工原紙が貼りついたり、エンボスの目詰まり、断紙等のトラブルが生じることがある。但し、原料配合や、パルプの叩解処理によって原紙強度をコントロールすることで、これらトラブルを回避できるので、塗工後にエンボスを施してもよい。又、塗工後にエンボスを施せば、エンボスがしっかりと掛かるというメリットがある。 Further, since the water absorbency of the base paper affects the coating speed and the coating uniformity of the water-soluble moisturizing component and / or the soft component, the base paper excellent in water absorbability is preferable. For example, the water absorption speed of the base paper by the 0.1 ml dropping method is preferably 5 seconds or less, more preferably 1 second or less. Here, in the 0.1 ml dropping method, 0.1 ml of distilled water at a temperature of 20 ± 1 ° C. is dropped onto the base paper from a height of about 10 mm, and when the water droplet contacts the paper, it is completely absorbed and the reflected light is It means the time until it disappears. Further, it is generally known that the water absorption speed of the base paper is affected by the raw material composition and the surface treatment by embossing and the like, and the water absorbability is reduced if the raw material contains waste paper. Therefore, it is preferable to emboss the base paper before coating because the water absorbability is improved.
In addition, when embossing is performed after coating, since the embossing is performed in a wet state, the coated base paper may stick to the embossing portion, and problems such as clogging of the embossing and breakage of the paper may occur. However, since these problems can be avoided by controlling the strength of the base paper by blending the raw materials and refining the pulp, embossing may be performed after coating. Also, if embossing is performed after coating, there is an advantage that the embossing is firmly applied.
　又、シートの少なくとも片面の全面には、水溶性保湿成分及び／又は柔軟成分が塗工されている。これらの成分により、使用時の風合いに優れたトイレットペーパーが得られる。
　水溶性保湿成分は、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、又はポリエチレングリコール等の多価アルコール類；ソルビトール、グルコース、キシリトール、マルトース、マルチトール等の多糖類；セタノール、ステアリルアルコール、又はオレイルアルコール等の高級アルコールの水溶性化誘導体又は乳化物；の群から選ばれる１種以上（Ａ）を含むと好ましい。
　又、柔軟成分は、アミノ変性シリコーン、親水性ポリエーテル変性シリコーンなどのポリシロキサン系柔軟剤、非イオン型界面活性剤（ポリエチレングリコール脂肪酸エーテル、ポリエチレンエーテル、多価アルコール脂肪酸エステル等）、カチオン型界面活性剤（4級アンモニア塩型、アミン塩型）、両性型界面活性剤、及びアニオン型界面活性剤の群から選ばれる１種以上（Ｂ）を含むことが好ましい。
　水溶性保湿成分（A）と、柔軟成分（Ｂ）を併用する場合には、質量比で（Ａ）：（Ｂ）＝９９．５：０．５～８０：２０とするとよい。 In addition, a water-soluble moisturizing component and / or a soft component is coated on the entire surface of at least one side of the sheet. By these components, the toilet paper excellent in the feel at the time of use is obtained.
Water-soluble moisturizing ingredients include polyhydric alcohols such as glycerin, diglycerin, propylene glycol, 1,3-butylene glycol or polyethylene glycol; polysaccharides such as sorbitol, glucose, xylitol, maltose, maltitol, etc .: cetanol, stearyl alcohol Or at least one member (A) selected from the group consisting of water-solubilized derivatives or emulsions of higher alcohols such as oleyl alcohol.
In addition, the soft component includes amino-modified silicone, polysiloxane-based softener such as hydrophilic polyether-modified silicone, nonionic surfactant (polyethylene glycol fatty acid ether, polyethylene ether, polyhydric alcohol fatty acid ester, etc.), cationic interface It is preferable to include one or more kinds (B) selected from the group of activators (quaternary ammonia salt type, amine salt type), amphoteric surfactants, and anionic surfactants.
When the water-soluble moisturizing component (A) and the soft component (B) are used in combination, it is preferable that the mass ratio is (A) :( B) = 99.5: 0.5 to 80:20.
　又、水溶性保湿成分及び／又は柔軟成分がシートの片面又は両面に対して合計１～１５質量％の割合で塗工されていると好ましい。水溶性保湿成分の割合が１質量％未満であると、トイレットペーパーに十分な風合いを付与することが難しいことがある。一方、水溶性保湿成分及び／又は柔軟成分の割合が１５質量％を超えると、水溶性保湿成分を塗工した際に原紙が破れてしまい、塗工ができなくなる場合がある。又、水溶性保湿成分及び／又は柔軟成分の割合が１５質量％を超えると、後述するように複数の塗工領域を間隔を空けて塗工する場合に、塗工領域と非塗工領域の境界が際立ち、境界でのシワやヨレが生じやすくなる。 In addition, it is preferable that the water-soluble moisturizing component and / or the soft component be coated at a ratio of 1 to 15% by mass in total on one side or both sides of the sheet. When the proportion of the water-soluble moisturizing component is less than 1% by mass, it may be difficult to impart sufficient texture to the toilet paper. On the other hand, when the ratio of the water-soluble moisturizing component and / or the soft component is more than 15% by mass, the base paper may be broken when the water-soluble moisturizing component is applied, and the application may not be possible. In addition, when the ratio of the water-soluble moisturizing component and / or the soft component exceeds 15% by mass, when coating a plurality of coated areas at intervals as described later, the coated area and the non-coated area Boundaries stand out and wrinkles and twists are likely to occur at the boundaries.
　次に、図１～図２を参照し、本発明の実施形態に係るトイレットペーパーロールの塗工方法について説明する。
　図１は、原紙（シート）２表面に水溶性保湿成分をロール塗工する方法を示す斜視図である。トイレットペーパーロールの原反ロール１０はリワインドされ、シートの原紙２が一対のエンボスロール５０，５１間を連続的に通されてエンボス加工される。次に、エンボス加工後の原紙２は、後述する塗工ロール装置２０により水溶性保湿成分（液状）を塗工された後、巻き取りロール１２に巻き取られる。巻き取りロール１２に巻き取られた原紙は、適宜製品サイズの幅に切断されてトイレットペーパーロールとなる。
　なお、原紙２に上記水溶性保湿成分及び／又は柔軟成分を塗工すると、原紙２の嵩及び強度が幾分か低下するが、水溶性保湿成分及び/又は柔軟成分を塗工する前に原紙２にエンボス加工を施すと、エンボスによるシート取られが起きにくく操業が安定する。 Next, with reference to FIGS. 1 and 2, the coating method of the toilet paper roll according to the embodiment of the present invention will be described.
FIG. 1 is a perspective view showing a method of roll-coating a water-soluble moisturizing component on the surface of a base paper (sheet) 2. The raw fabric roll 10 of the toilet paper roll is rewound, and the base paper 2 of the sheet is embossed by being continuously passed between the pair of embossing rolls 50, 51. Next, the base paper 2 after embossing is coated with a water-soluble moisturizing component (liquid) by a coating roll device 20 described later, and then wound around the winding roll 12. The base paper taken up by the take-up roll 12 is appropriately cut into a product size width to be a toilet paper roll.
In addition, when the water-soluble moisturizing component and / or the soft component is coated on the base paper 2, the bulk and strength of the base paper 2 are somewhat reduced, but before the water-soluble moisturizing component and / or the soft component are coated When 2 is embossed, sheet removal by embossing is less likely to occur and operation is stabilized.
　ここで、図２に示すように、塗工ロール装置２０は、塗工液溜め１３、塗工液溜めの塗工液に接するピックアップロール１７、ピックアップロール１７から塗工液を供給されて塗工液の量を調節するアニロックスロール１４、原紙２に塗工する版ロール１５を備えており、ピックアップロール１７、アニロックスロール１４、版ロール１５はこの順で下から上に並んでいる。
　図２の例では、版ロール１５は周方向に沿って複数の凸部が等間隔に設けられており、ローション塗工量の調整は、アニロックスロール１４の線数及びアニロックスロール１４とピックアップロール１７のクリアランスによりコントロールする。そして、版ロール１５により、原紙２の流れ方向（ＭＤ）に略平行して、原紙２表面に上記水溶性保湿成分及び／又は柔軟成分が筋状に塗工される。
　なお、原紙２表面に筋状に塗工する方法としては、ロール塗工に限られず、例えばスプレー塗工、印刷塗工を用いることができる。
　また、塗工する水溶性保湿成分及び／又は柔軟成分の液粘度は２５℃で２００ｃＰ（ｍＰａ・ｓ）以下であれば安定して塗工でき、より望ましくは２０～１００ｃＰ（ｍＰａ・ｓ）である。粘度が高すぎると原紙への移行が悪くなり、ムラが生じやすく塗布スピードも低下することがある。 Here, as shown in FIG. 2, the coating roll device 20 is supplied with the coating liquid from the coating liquid reservoir 13, the pickup roll 17 in contact with the coating liquid reservoir of the coating liquid reservoir, and the pickup roll 17. An anilox roll 14 for adjusting the amount of liquid and a plate roll 15 for coating the base paper 2 are provided, and the pickup roll 17, the anilox roll 14, and the plate roll 15 are lined up in this order from the bottom.
In the example of FIG. 2, the printing roll 15 is provided with a plurality of convex portions at equal intervals along the circumferential direction, and adjustment of the lotion coating amount is performed by adjusting the number of lines of the anilox roll 14 and the anilox roll 14 and the pickup roll 17. Controlled by the clearance of Then, the water-soluble moisturizing component and / or the flexible component is applied in a streak shape on the surface of the base paper 2 substantially parallel to the flow direction (MD) of the base paper 2 by the printing roll 15.
In addition, it is not restricted to roll coating as a method of coating on the base paper 2 surface like a streak, For example, spray coating and printing coating can be used.
If the liquid viscosity of the water-soluble moisturizing component and / or the soft component to be applied is 200 cP (mPa · s) or less at 25 ° C., stable coating can be performed, and more preferably 20 to 100 cP (mPa · s) is there. If the viscosity is too high, the transfer to the base paper may be poor, and unevenness may easily occur, and the coating speed may also decrease.
　図３は、原紙２表面に上記水溶性保湿成分及び／又は柔軟成分が塗工された状態を示す。塗工直後（図３（ａ））では、塗工パターンに対応した間隔ｄで塗工領域４ａがMD方向に沿って筋状に形成され、隣接する塗工領域４ａ間が非塗工領域４ｂになっている。又、塗工領域４ａは幅ｗで塗工されている。
　このように、塗工領域４ａはＭＤ方向に連続するが、ＣＤ方向には連続しない。そして、塗工領域４ａでは水溶性保湿成分及び／又は柔軟成分を含むために原紙２の強度が低下するが、連続する非塗工領域4ｂを有することで原紙２が断紙し難くなり、安定して生産を行うことができる。
　そして、塗工してしばらく経過すると（図３（ｂ））、原紙２の紙（セルロース）繊維と親和性の高い水溶性保湿成分及び／又は柔軟成分が原紙２のＣＤ方向に浸透して非塗工領域４ｂに拡散し、通常１～３分経過後に原紙２の全面に水溶性保湿成分及び／又は柔軟成分が浸透し、筋（縞）模様が消える。このようにして、水溶性保湿成分及び／又は柔軟成分が全面に塗布されたトイレットペーパーロールを製造することができる。 FIG. 3 shows a state in which the water-soluble moisturizing component and / or the soft component is coated on the surface of the base paper 2. Immediately after coating (FIG. 3 (a)), the coating area 4a is formed in a stripe shape along the MD direction at the interval d corresponding to the coating pattern, and the non-coating area 4b is between adjacent coating areas 4a. It has become. Moreover, the coating area 4a is coated by width w.
Thus, the coated area 4a is continuous in the MD direction but not continuous in the CD direction. And in the coating area 4a, the strength of the base paper 2 is lowered because it contains the water-soluble moisturizing component and / or the soft component, but by having the continuous non-coating area 4b, the base paper 2 becomes difficult to break and stable. Production can be done.
Then, after a while after coating (FIG. 3 (b)), the water-soluble moisturizing component and / or the flexible component having high affinity with the paper (cellulose) fiber of the base paper 2 penetrate in the CD direction of the base paper 2 The water-soluble moisturizing component and / or the soft component permeates the entire surface of the base paper 2 after 1 to 3 minutes, and the streaks disappear. In this way, a toilet paper roll having a water-soluble moisturizing component and / or a soft component applied to the entire surface can be manufactured.
　なお、塗工領域４ａの塗工幅ｗを1ｍｍ～10ｍｍとすると好ましい。塗工幅ｗが1ｍｍ未満の場合、均一な塗工が難しく、塗工幅にバラツキが生じやすい。塗工幅ｗが１０ｍｍを超えると、塗工領域が広くなり過ぎて、塗工領域での原紙膨潤が著しく、非塗工領域との境界にシワが発生しやすいと共に断紙が生じやすい。塗工間隔ｄは2～10mmとすると好ましい。2mm以下では非塗工領域が狭すぎて断紙が生じやすい。また10mm以上では非塗工領域が大きすぎて品質にバラつきが生じやすい。塗工時の非塗工面積の比率は全面積に対して４０～８０%が望ましい。４０%未満では断紙が生じやすく、８０%を超えると成分の拡散が不均一でムラが生じやすい。 The coating width w of the coating area 4a is preferably 1 mm to 10 mm. When the coating width w is less than 1 mm, uniform coating is difficult, and the coating width tends to vary. If the coating width w exceeds 10 mm, the coated area becomes too wide, the base paper swells significantly in the coated area, wrinkles are easily generated at the boundary with the non-coated area, and the paper is easily broken. The coating interval d is preferably 2 to 10 mm. If it is 2 mm or less, the non-coated area is too narrow, and paper breakage is likely to occur. Moreover, in 10 mm or more, a non-coating area | region is too large, and it is easy to produce variation in quality. The ratio of non-coated area at the time of coating is preferably 40 to 80% of the total area. If the amount is less than 40%, sheet breakage is likely to occur, and if it exceeds 80%, the diffusion of the components is uneven and unevenness is likely to occur.
　なお、上記したロール塗工に代えて、原紙２表面に筋状に印刷塗工した場合でも、筋状の非塗工領域で強度を保持することができる。 In addition, even when printing is applied on the surface of the base paper 2 in the form of streaks instead of the above-described roll coating, the strength can be maintained in the streaky non-coated area.
　本発明は上記した実施形態に限定されず、本発明の思想と範囲に含まれる様々な変形及び均等物に及ぶことはいうまでもない。
　例えば、上記した塗工ロール（版ロール）による原紙２表面への水溶性保湿成分及び／又は柔軟成分の塗工は、プライマシンで複数枚のプライとした原反ロール１０に対して行うことが好ましい。又、原紙２の両面に塗工する場合は、２個の塗工ロール（版ロール）をそれぞれ原紙２の表裏に置くのが好ましく、その場合には、原紙２表面の塗工領域４ａと裏面の塗工領域４ａとの位置をずらした方がよい。
　又、水溶性保湿成分及び／又は柔軟成分を原紙に直接塗工してもよく、水溶性保湿成分を溶媒（水等）で薄めて原紙に塗工してもよい。 It goes without saying that the present invention is not limited to the embodiments described above, but extends to various modifications and equivalents included in the spirit and scope of the present invention.
For example, the coating of the water-soluble moisturizing component and / or the flexible component on the surface of the base paper 2 by the coating roll (plate roll) described above may be performed on a plurality of ply original rolls 10 with a ply machine. preferable. Moreover, when coating on both sides of the base paper 2, it is preferable to place two coating rolls (plate rolls) on the front and back of the base paper 2 respectively. In that case, the coated area 4a and the back surface of the base paper 2 surface It is better to shift the position of the coating area 4a from the above.
Further, the water-soluble moisturizing component and / or the soft component may be directly coated on the base paper, or the water-soluble moisturizing component may be diluted with a solvent (such as water) and coated on the base paper.
　図２に示す塗工ロール装置２０を用い、トイレットペーパーの原紙２表面に水溶性保湿成分及び柔軟成分を筋状に塗工した。なお、１６０メッシュのアニロックスロール１４を用い、版ロール１５はＷ：2mm～4ｍｍ幅の等間隔、ｄ：2～10mmを用いた。塗工量はアニロックスロール１４の線数及びアニロックスロール１４とピックアップロール１７のクリアランスによりコントロールし、原紙２の幅（1650ｍｍ）とした。原紙２は2PLYで、１枚当り約１８ｇ/ｍ2で全体の坪量は約３６ｇ/ｍ2とし、上述の0.1ｍｌ滴下法による吸水速度１秒以下のものを用い、塗工前にエンボス加工を行った。エンボス形状はオーバルパターン（スチール／ラバー片面　オーバル1.5×2ｍｍ、8個/ｃｍ2）とし、ニップ深さ0.7ｍｍとした。
　そして、表１に示す運転速度及び塗工量で、水溶性保湿成分及び柔軟成分を原紙２の片面に塗工を行った。なお、水溶性保湿成分及び柔軟成分は、ポリエーテル変性ジメチルシリコーン2wt％、グリセリンwt98％の組成とし、比重1.25g/cm3、粘度70CP（25℃）とした。
　なお、比較例１として、原紙２にエンボス加工のみ行い、水溶性保湿成分を塗工しなかったものを用意した。 The water-soluble moisturizing component and the soft component were streaked on the surface of the base paper 2 of the toilet paper using the coating roll apparatus 20 shown in FIG. A 160 mesh anilox roll 14 was used, and the plate roll 15 used W: 2 mm to 4 mm wide and d: 2 to 10 mm at regular intervals. The coating amount was controlled by the number of lines of the anilox roll 14 and the clearance between the anilox roll 14 and the pickup roll 17 to obtain the width (1650 mm) of the base paper 2. The base paper 2 is 2PLY, about 18 g / m 2 per sheet, and the overall basis weight is about 36 g / m 2, and the one with a water absorption speed of 1 second or less by the above-mentioned 0.1 ml dropping method is embossed before coating Did. The embossed shape was an oval pattern (steel / rubber single-sided oval 1.5 × 2 mm, 8 pieces / cm 2 ), and the nip depth was 0.7 mm.
Then, the water-soluble moisturizing component and the soft component were coated on one side of the base paper 2 at the operation speed and the coating amount shown in Table 1. The water-soluble moisturizing component and the flexible component were composed of 2 wt% of polyether modified dimethyl silicone and 98 wt% of glycerin, and had a specific gravity of 1.25 g / cm 3 and a viscosity of 70 CP (25 ° C.).
In addition, as Comparative Example 1, only the embossing was performed on the base paper 2, and the one in which the water-soluble moisturizing component was not applied was prepared.
　塗工後のトイレットペーパーにおいて、縦及び横の引張強度は、JIS-P8113に基づき、試験片幅25mｍ幅にて測定した。塗工後のトイレットペーパーのハンドフィールは、複数のパネラーの官能により、以下の１～5の５段階評価を行い、その平均とした。
　　１(かなり硬い)　２、（やや硬い）、３（普通）、4(かなり柔らかい)、５(極めて柔らかい) 
　ほぐれ易さは、JIS-P4501に準拠して測定した。 In the toilet paper after coating, the tensile strength in the longitudinal and transverse directions was measured with a test piece width of 25 mm in accordance with JIS-P8113. The hand feel of the toilet paper after coating was evaluated on the basis of the following five to five evaluations by the functions of a plurality of panelists, and the average was obtained.
1 (very hard) 2, (somewhat hard), 3 (normal), 4 (very soft), 5 (very soft)
The ease of loosening was measured in accordance with JIS-P4501.
　外観は、〇：シワ等の発生がない、△：ややシワの発生がある、×：塗工ムラがある，シワの発生が大きい、の基準で評価した。
　得られた結果を表１に示す。表１の塗工量は、トイレットペーパーのシートに対する水溶性保湿成分及び柔軟成分の質量割合である。 The appearance was evaluated according to the following criteria: な い: no occurrence of wrinkles, Δ: some occurrence of wrinkles, x: uneven coating, large occurrence of wrinkles.
The obtained results are shown in Table 1. The coating amount in Table 1 is the mass ratio of the water-soluble moisturizing component and the soft component to the sheet of toilet paper.
Figure JPOXMLDOC01-appb-T000001
Figure JPOXMLDOC01-appb-T000001
　表１から明らかなように、トイレットペーパーの片面全体に水溶性保湿成分を塗工した各実施例の場合、塗工を行わなかった比較例１に比べてハンドフィールが優れたものとなった。
　又、各実施例は、比較例１に比べて強度の低下割合が30％以下、紙厚（嵩）の低下割合が10％以下ですみ、使用上問題ないレベルである。 As is clear from Table 1, in each of the examples in which the water-soluble moisturizing component was coated on the entire surface of the toilet paper, the hand feel was excellent compared to Comparative Example 1 in which the coating was not performed.
In each example, the strength reduction rate is 30% or less and the paper thickness (bulk) reduction rate is 10% or less as compared to Comparative Example 1, and there is no problem in use.
　一方、水溶性保湿成分の塗工量が15wt％を超えた比較例２の場合、ハンドフィールは良いが、比較例１に比べて強度が40％程度低下し、嵩（紙厚）が15％程度低下した。また、比較例２の場合、塗工量が多いため、塗工領域４ａと非塗工領域４ｂ（図３（ａ）参照）でトイレットペーパーの伸びが異なり、シワ（縮れ模様）が現れ、幅方向に若干の塗工ムラが見られ外観がやや劣った。 On the other hand, in the case of Comparative Example 2 in which the coating amount of the water-soluble moisturizing component exceeds 15 wt%, the hand feel is good, but the strength is reduced by about 40% compared to Comparative Example 1 and the bulk (paper thickness) is 15%. It decreased to some extent. Further, in the case of Comparative Example 2, since the coated amount is large, the elongation of the toilet paper is different between the coated area 4a and the non-coated area 4b (see FIG. 3A), and wrinkles (crimped pattern) appear. Some coating unevenness was seen in the direction and the appearance was a little inferior.
