201221100 六、發明說明： 【發明所屬之技術領域】 本發明係關於一種以衛生紙為代表的水溶性衛生紙。 【先前技術】 已热知有作為水溶性衛生紙之衛生紙。對於該種水溶 性衛生紙，為了提高擦拭性能，並且體現蓬鬆度、柔軟性、 表面之光滑度’而有時實施壓紋加工。 從由具有伸縮性、低基重且較薄之皺紋紙所構成之水 溶性衛生紙之特徵而言，通常，此種壓紋加工係藉由將形 成有複數個壓紋凸部之金屬製壓紋輥與具有承受該等壓紋 凸部之彈性表面之彈性輥組合成一對之鋼橡膠方式而進 行。 另方面，對於賦予至積層有鈹紋紙之水溶性衛生紙 上之壓紋，將於鋼輥與橡膠輥間將壓紋賦予至皺紋紙後而 積層之形態、或於鋼輥與鋼輥間將壓紋施加於片材之表面 與裏面之類型稱為雙壓紋，而將積層有複數個皺紋紙後而 賦予壓紋之形態稱為單壓紋來區別（其中，單壓紋並不限 定於經積層之皺紋紙）。 上述雙壓紋藉由使賦予之凸單位壓紋之頂部彼此接 觸，而有可製造蓬鬆且具有厚度、兩面之光滑度之差較小 的水溶性衛生紙之優點’另一方面，有必需有與積層之皺 紋紙數對應之壓紋親之缺點。又，由於積層之皺紋紙之接 觸面積變小’故而於將糊劑用於積層一體化之情形時，亦 201221100 有水溶性較差之缺點。 十此，單壓紋只要利用用以一次將壓紋賦予至已積層 之皺紋紙上之一個壓紋輥即可，並且由於該壓紋亦有助於 皱紋紙彼此之積層—體化，&而有不需要糊劑即可製成< 溶性優異之水溶性衛生紙之優點，另—方面，由於無法使 露出之紙厚增加至金屬製壓紋輥之壓紋凸部之高度以上， 故而有難以體現蓬鬆度之缺點。 此處’於鋼橡膠方式中，由於藉由使壓紋凸部壓入彈 改親中而賦予壓紋，故而為以單壓紋形態賦予蓬鬆且較深 之壓紋’而利用具有高度之壓紋賦予凸部賦予壓紋，或者， 藉由提高壓紋壓等，而可體現蓮鬆度，但於此種對策中， 產生被心文之面即接觸金屬親之紙面變得⑽光滑度變 差’或纖維緊實作為單壓紋之優點的水溶性變差，或紙自 身良薄黏度消失之弊病。又，由壓紋凸部擠壓而形成之凹 部之特別是底部之纖維緊實，且顯現出不需要之光澤，式 樣性亦低劣。 [先前技術文獻] [專利文獻] [專利文獻1]曰本專利特開2009 178572號公報 [專利文獻2]日本專利特開2〇〇6 81883號公報

Description of the Invention: [Technical Field of the Invention] The present invention relates to a water-soluble toilet paper typified by toilet paper. [Prior Art] Toilet paper as a water-soluble toilet paper has been known. In such a water-soluble toilet paper, embossing is sometimes performed in order to improve the wiping performance and to exhibit bulkiness, flexibility, and smoothness of the surface. From the characteristics of water-soluble toilet paper composed of stretchable, low basis weight and thin wrinkle paper, usually, such embossing is performed by embossing a metal formed with a plurality of embossed convex portions. The roller is formed by a steel rubber method in which a pair of elastic rollers having an elastic surface that receives the embossed convex portions are combined. On the other hand, for the embossing applied to the water-soluble toilet paper having the crepe paper laminated thereon, the embossing is applied to the crepe paper between the steel roller and the rubber roller to form a layer, or between the steel roller and the steel roller. The type in which the embossing is applied to the surface and the inside of the sheet is called double embossing, and the form in which a plurality of crepe papers are laminated and the embossing is given is called a single embossing (wherein, the single embossing is not limited to Merged crepe paper). The double embossing has the advantage of being able to produce a water-soluble toilet paper which is bulky and has a small difference in smoothness between the two sides by the contact of the tops of the convex embossments imparted thereto. On the other hand, it is necessary to have The number of crepe papers in the layer is the disadvantage of the embossing. Further, since the contact area of the laminated crepe paper becomes small, the use of the paste for the integration of the laminate is also a disadvantage of the poor water solubility of 201221100. In this case, the single embossing may be performed by using one embossing roller for imparting embossing to the laminated crepe paper at one time, and since the embossing also contributes to the lamination of the crepe paper, & There is an advantage that a water-soluble toilet paper having excellent solubility can be obtained without a paste, and on the other hand, it is difficult to increase the thickness of the exposed paper to the height of the embossed convex portion of the metal embossing roll. Reflects the shortcomings of fluffiness. Here, in the steel-rubber method, since the embossing convex portion is pressed into the elastic modification to impart embossing, the embossing is applied to the fluffy and deep embossing in a single embossed form, and the pressure is high. The embossing is imparted to the convex portion by the embossing, or the embossing pressure or the like is increased, and the degree of lotusness can be expressed. However, in such a countermeasure, the surface of the heart, which is the surface of the contact metal, becomes smooth (10). Poor' or fiber compaction is the water solubility of the advantages of single embossing, or the paper's own thin viscosity disappears. Further, the concave portion formed by the embossing convex portion, particularly the fiber at the bottom portion, is compact and exhibits an undesired gloss, and the pattern is also inferior.

[Effects of the Invention] According to the present invention described above, it is possible to improve the bulkiness of the water-soluble toilet paper using a single embossing using a steel rubber method and the smoothness of the paper surface. [Embodiment] Next, the best examples are shown in Figs. 6 to 6 and the embodiments of the present invention will be described in detail below with reference to Figs. The water-soluble toilet paper X of the present invention has an embossing, and is preferably provided with a layer structure (layered structure) in which two or more layers of sensitized paper are laminated and imparted to the embossing. The number of the layers is not particularly limited. However, if the number of layers is too large, the water/compatibility is deteriorated, and the difference in smoothness in the surface is large, which tends to cause separation of the layers. Therefore, it is preferably 2 to 3 layers. Further, it is preferable that the photosensitive paper for constituting the layer of the water-soluble thread χ ι of the present invention has a thickness of WO 〜 200 " m. When it is less than 100 _, there is a rupture when embossing is applied. When 2 〇〇" m, embossing cannot be firmly printed, and embossing of the invention of the present application cannot be fully exerted. The effect of shape and embossed pattern. On the other hand, the embossing of the water-soluble toilet paper of the present invention is a single embossing imparted by the steel 7 201221100 = mode. That is, the embossing of the water-soluble toilet paper X1 of the present invention is such that the crepe paper S1 or the laminated crepe paper S1 is interposed between the convex embossing roller and the peripheral surface elastic view which are disposed in parallel with the rotation axis, and the embossing is performed. And, the concave portion transferred to the crepe paper material becomes the convex portion of the other surface, and the embossing of the paper surface is exposed on both sides, whereby the present invention is embossed by a method such as a so-called steel mold One of them is different for the convex embossing roller. Although the steel mold embossing can be applied, the paper pulp fiber is used to break the paper in the process of giving the crepe in the crepe paper... by == crepe paper is easy ^, Tian Yu Since the present invention has a characteristic small convex portion group, it is difficult to provide a steel mold embossing method. Further, in the present invention, it is not a double embossing which is applied to each crepe paper as a so-called kiss type.

And 'because of a single embossing, so no need The outer embossed paper is therefore easy to manufacture. Moreover, the composition of the embossed embossing can be used to achieve the desired effect of the water-soluble toilet paper of the invention. Preferably, the circumferential surface is an elastic nip roller composed of a member. The surface hardness of the surface is ^h〇reh ^ °1"The surface of the raw roll is too soft, and the crepe paper S1 is broken when the pattern is given 201221100 On the one hand, if the hardness of the Xiao type is too high, that is, if the circumferential elastic roller has a pattern in which the circumferential surface i of the convex embossing roll 60 cannot be transferred, it is preferable to gamble. Corrosion, nip pressure (also known as embossing pressure, line pressure) is 5~3〇kgf/cm' is preferably i〇~25kgf/em. If the pressure is too low, then there is In addition, the effect of the embossing becomes clear. On the other hand, if the right embossing pressure is too high, the sensitive paper S1 is cut off. Here, 'by the steel rubber method, the crepe paper smmZ is made of hard The unevenness of the peripheral surface i of the convex embossing roll 60 formed of a hard material such as a resin or a metal penetrates into the surface of the peripheral elastic ridge. Therefore, not only the convex portion of the periphery of the convex embossing roll 60 but also the shape of the concave portion is an important element. Further, the present invention is characterized by the pattern of the peripheral unevenness of the convex embossing roll 6〇. a concave portion 10 on a regularly arranged dome is formed on a circumferential surface i of the convex embossing roller 60, a strong pressing portion formed between the concave portions 1〇 from the bottom portion of the concave portion, and a concave portion from the concave portion a small convex group 12 formed by a plurality of small convex portions 12t projecting by a concave surface. The crepe paper S1 passing between the convex embossing roller 6〇 and the circumferential surface elastic roller 61 is slowly pressed into the dome. The concave portion 1〇 is held and held, and the concave embossing is firmly formed on the paper surface by the strong pressing portion 。, whereby the crepe paper s 1 can form the concave portion 无 without damage and deep. Accordingly, the concave embossing and the convex embossing on the opposite side thereof can be firmly formed by the strong pressing portion u having a relatively high height. (Further, the following 'in the case where the concave embossed portion is formed in the present invention A convex embossed portion is formed on the opposite side, but the description of 201221100 == may be omitted. ). Therefore, the bulkiness is obtained, and the cow is fixed to the concave I pattern, so that the pattern is also higher. Further, in the case where the history is a layer structure, the layer is firmly bonded by the layer of the concave I pattern. In the present invention, by the characteristic small convex portion 12, for the crepe paper 81 entering the concave portion 10, the crepe paper S1 is partially squeezed when the I grain is imparted by the small convex portion (2). The ridge line between the adjacent concave embossings formed by the strong pressing portion η is unclear and exhibits a softness pattern. Further, the convex portion forming surface t' of the paper surface forms a small convex portion corresponding to the small convex portion 12t, so that the convex embossing corresponding to the strong pressing portion 11 (corresponding to the portion of the concave I pattern) complements each other The density of the convex embossing of the entire paper surface is improved, and it has smoothness and is fluffy. Further, the portion which is pressed by the concave portion 10 is formed into a finer uneven portion by the small convex portion i2t, so that the light is diffused and reflected in the portion by the unevenness, and the matte is simple and has a high sense of high quality. In the pattern 1, the pattern is improved by the small convex portion 12t. Here, it is preferable that the planar shape of the concave portion H) formed on the circumferential surface of the convex embossing roller 6A and the concave portion H) has a rounded square shape and a rounded square shape of the adjacent concave portion. A pattern disposed while approaching or contacting each side of the rounded quadrangle of the recess 10. In particular, the shape of the concave portion is preferably a rounded square as shown. If the shape of the concave portion is such a rounded square, the smoothness of the paper surface is further increased. Further, in the present invention, since the concave portions 10 are regularly arranged, they are complemented by each other, and become a water-soluble toilet paper 10 201221100 呈现ι which exhibits an excellent pattern. Further, the term "top view" means that the peripheral surface of the embossing roll 60 is developed into a flat surface and is viewed from above. As exemplified above, in the pattern of the convex embossing rolls 60 in which the recessed portions 1 of the rounded corners are arranged, the strong pressing portion becomes a strong squeeze formed by the mountain portions surrounded by the * recesses 1 a portion 11A (also referred to as a mountain-shaped strong pressing portion) and a strong pressing portion 1 1B composed of a linear portion between the sides of the adjacent concave portions (hereinafter also referred to as a linear strong pressing portion) The combination. The linear portion 11B is provided to connect the mountain-shaped strong pressing portions to each other. Further, in the illustrated example, as a preferred example, the sides of the concave portion 1G are in contact with each other, and the linear strong pressing portion 1 1B becomes a line. Preferably, the distance between the edges of the adjacent recesses is set to be less than 2 〇 mm. The shape of the mountain-shaped strong pressing portion 11A can be reliably transferred. Further, in the above-described form, the mountain-shaped strong pressing portion UA forms a strong substantially rectangular concave embossing on the corrugated paper surface, and forms a linear concave embossing so as to be connected thereto. And effectively reflect the smoothness and softness of the surface. In order to further exhibit such an effect, it is preferable that the mountain-shaped strong pressing portion 11A and the pressing portion 11 are connected to the linear squeezing so as to face the arc of the axis u of the convex embossing roller 6〇. Pressing portion 11 b. In the formula, the linear embossing between the concave concave lines formed by the mountain-shaped strong pressing portion 11A is thinned, and only the concave pressure formed by the mountain-shaped strong pressing portion 11A is +___ tip In the vicinity of the square end, a linear concave embossing is formed, which is excellent in style. Further, if the 201221100 strong squeezing portion UA formed in the portion surrounded by the four recesses 1 is formed to have the top surface 11a, the top surface 11a is faced and pressed against the paper surface, so that the shape thereof The water-soluble toilet paper which is excellent in the pattern is obtained by being transferred to the paper surface with good visibility. In particular, if the top surface is rounded, it is possible to prevent the paper from being broken when the paper surface is transferred to the paper surface due to the absence of the corner portion. The water-soluble toilet paper obtained by ’ ’ has a smoothness on the paper surface. In addition, when the top surface 1 la is placed on the mountain-shaped strong pressing portion 丨i A, it is preferable that the side and the edge lle are chamfered. 9 The rupture of the rupture caused by the edge of the edge is eliminated, and the water-soluble toilet paper exhibits a surface that is slippery and provides a soft impression. Here, it is preferable that the area of the planar shape of the recess 1G is 8 to 12 mm 2 . When it is less than 8 _2, it is difficult to form the small convex group u, and it is difficult to reflect the improvement of the smoothness of the surface of the small convex group 12, the effect of the flu: degree, and the softness.

In particular, by setting it as a regular arrangement, it is possible to eliminate the unevenness which is excellent in the smoothness of the surface, such as the provision of the difference in the pressing force in each of the strong pressing portions 1A, and the concave pressure formed by the strong pressing portion Ha. The pattern does not become unclear and the pattern is also excellent. Here, the protruding direction of the small convex portion 12t is the same as the convex direction of the strong pressing portion 11A, and the direction is the direction of the center of the convex embossing roll 60 and the circumferential direction, that is, the connection with respect to the circumferential surface. The face becomes the vertical direction. Further, it is preferable that the height position of the top of the small convex portion 1 2 is set to be the same as or slightly lower than the position of the strong pressing portion. This height position refers to the distance from the axis of the embossing roller 60. The top of the small convex portion 12t is the same as the top portion of the strong pressing portion 11A surrounded by the four concave portions 1 ,, and is preferably a flat surface, and it is preferable that the area of the top surface is 〇. 2~ 〇.5 mm2. The shape of the top view is ideal for rounding. If it is within this range, the expression of the bulkiness of the small convex portion group 12 and the smoothness can be effectively exhibited. Further, if the number of the small convex portions 12t constituting the small convex portion group 12 exceeds 6 <solid, the concave embossing of the paper surface formed by the strong pressing portion 11A is apt to become unclear. Preferably, the number of the small convex portions 12t in the small convex group 12 is not five as shown in the figure, and the arrangement is also as shown. That is, it is desirable that four of the five are far away. The line of the center or the vertex of the top surface is depicted as a quadrangle or a square. The remaining one is arranged at the center of the four-corner path of the depiction. . 13 201221100 With this arrangement, when transferred to the crepe paper s丨, the smoothness and the bulkiness of the portion corresponding to the concave portion ι are apparent. Here, if the preferred regular arrangement of the small convex group 12 is described, it is preferable that the small convex group 12 is arranged one by one in the longitudinal direction as shown in the example. In view of the relationship with the recess 10, it is preferable that the above-described quadrilateral has 45 with respect to the rounded quadrangle of the recess 10. Further, it is preferable that the small projections i constituting the small convex portion group 12 are arranged so as to be located at the center of the concave portion 10 in the plan view. In the case of such an arrangement, the pattern is excellent, and the concave embossing of the paper surface formed by the strong pressing portion i 1A on the paper surface becomes firm' and the small convex portion group is formed with respect to the portion pressed by the concave portion 10 The bump is thus made to have a loose, smooth paper surface. On the other hand, when the concave embossing of the water-soluble sanitary paper XI formed by the above-described convex embossing roll 60 is described, the depth of the concave embossing is desirably 400 / zm. More preferably 35〇~375 "m. It is difficult to ask the fluffiness when it is less than 3, and if it exceeds 4 〇〇 " m, there is a flaw in the paper. Further, the depth of the concave embossing here is measured by a microscope. The numerical value is used to select the average value of the parts of the two embossed parts. Further, the sense can be measured using, for example, a microscope manufactured by KEYENCE. Further, in particular, it is assumed that the case of A 1 K and the case of the water-soluble hygiene of the present invention XI also exerts the effect that the difference in the smoothness of each side of the paper surface is small. On the other hand, the water-soluble toilet paper of the present invention is provided. In order to give it by the upper = characteristic convex embossing 胄 60, the mmd of the paper surface can be

In particular, in the present invention, it is preferable that at least one surface of the MMD is set to be 0.080 or less. Furthermore, if the value of MMD 201221100 exceeds 0·010, the smoothness of the surface is poor. Even if it does not reach 〇 〇 6, it feels rough. Further, the MMD system here is the average deviation MMD of the friction coefficient of the 10 mm square piano wire terminal and the toilet paper measured under the conditions specified in ns Ρ 8111 as shown in Fig. 6 . The average deviation mmd of the friction coefficient can be measured using a "friction sensation tester Μ SE" manufactured by Kats Tech Co., Ltd. This means that the larger the MMD value, the worse the smoothness. Furthermore, if
