The invention's effect

[0014] The tissue paper of the present invention is (A) a tissue paper having a rice tsubo of 10.0 to 25.

OgZm ² (preferably 11.0 to 17. Og / m ² ) (B) Three sets of the same size tissue paper are stacked to form one set. (C) Tissue paper width and width dimensions Satisfies each condition of 160 to 24 Omm, so it is applied to the skin, especially because it is a set of 3 sheets of a given rice tsubo or a set of more than 3 sheets. It has excellent cushioning properties (soft feeling) when used, and has no or little breakage during use, especially during cleansing. In addition, the width and length of the tissue paper are 160-240mm (preferably 180-220mm), so that when folded in four, women who have excess in the make-up operation can easily hold and handle by hand. .

[0015] Total paper strength 200-400 m (preferably 200-340 μm), wet? When the leap force is 42.5—100 cN (preferably 42.5—55. OcN) and the oil absorbency is 1.1 to 39.0 seconds (preferably 18.0—35.0 seconds), For example, it is possible to quickly and quickly remove the oil attached to the skin as well as to reduce the number of breaks.

[0016] At least two folded outer surfaces of a pair of tissue papers in a stack of three sheets include a polysiloxane such as silicone oil and silicone powder, glycerin, and propylene glycol. By applying at least one of polyhydric alcohols such as sorbitol, glucose such as glucose, glycol solvents and derivatives thereof, the surface can be given a smooth feel and flexibility.

[0017] The agent is preferably has been coated at a ratio of 0. 46-0. 98g / m ² with respect to the application target surface. Would like feel agents coated amount sticking to the skin without a smooth feel is less than 0. 46 g / m ² with respect to the application target surface, greater than 0. 98gZm ² when the drug is released from Tisshube one per skin The above range is preferable because it gives a feeling of stickiness to move to.

[0018] The tissue paper of the present invention is folded in two by a pop-up method, stored in a vertically long rectangular parallelepiped storage box, and used for use. If the vertical dimension ratio of the mouth is 0.1-0.6, and the horizontal dimension ratio is 0.02-1.0, it is easy to take out and excessively large. Mixing can be prevented.

[0019] Further, if the ratio of the vertical dimension Z horizontal dimension in the storage box is 1.5-2.0, and the (bottom area) ^1/2 Z height ratio is 1.0-2.0, Convenience for consumers in relation to the external dimensions of the tissue paper, the stability when placed and used, and the number of sets in the storage box (preferably 100-150 sets) It becomes.

[0020] If the filling rate of the tissue paper in the storage box is 50-200 pairs and Z85mm height, the storage items collapse due to the increase of the play space due to the excessively low filling rate, and the quality is deteriorated due to the movement. It is possible to prevent dangling and prevent breakage at the time of removal due to an excessively high filling rate. BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, the present invention will be described in more detail by giving best modes for carrying out the present invention.

As the base paper of the tissue paper of the present invention, NBKP content is 30-80%, LBK

P20-It is desirable to use 70% pulp fiber as the main raw material. If necessary, it is desirable to mix 100% of pulp non-pulp, which can mix waste paper pulp with 30% or less, and preferably 10% or less, with respect to the kneap raw material.

[0022] One piece of tissue paper has a rice tsubo of 10.0 to 25. OgZm ² (preferably 11.0 to 17. Og

Zm ² ). The commercial product is 12.8-18.3 gZm ² . In the present invention, If the force is too small, the above-mentioned cushioning properties cannot be obtained. As can be seen in the examples of commercially available products, it is possible to increase cushioning properties by stacking two sheets of rice tsubo that are larger in rice tsubo. By using one (or more sheets) as a set, the slight space between the sheets is used as a buffer space to improve cushioning. In addition, even if the total thickness is the same as that of a set of two sheets and one set of three sheets, even if the total thickness is the same, it is found that the oil absorbency of the one set of three sheets is superior. Was done. This was presumed to be due to the function of retaining oil in the powerful space between the sheets.

[0023] Each width and length of the tissue paper is 160 to 240 mm (preferably 180 to 220 mm). With this size, when folded in four, there is no extra space during makeup operation.

[0024] Total paper thickness 200-400 m (preferably 200-340 μm), wet? Leap force 42.5-100 cN (preferably 42.5-55. OcN), oil absorbency 1.1-13.0 seconds (preferably 18.0-35.0 seconds) is desirable. The total paper thickness is specified to ensure cushioning. The vertical and horizontal wet paper strength (also the dry paper strength) are measured based on JIS S 3104 and JIS P 8113. The wet paper strength is important for wiping after washing the face. Making the wet paper strength too high is difficult because it impairs other properties (eg, flexibility). If the wet paper strength is low, breakage tends to occur. On the other hand, if the degree of oil absorption is high, cleansing properties are poor.

[0025] At least two folded outer surfaces of a pair of tissue papers in a stack of three, polysiloxanes such as silicone oil and silicone powder, polyhydric alcohols such as glycerin and propylene glycol, saccharides such as sorbitol and glucose, and glycols. By applying at least one of the system solvent and its derivative, a smooth surface feel and flexibility can be given.

[0026] If necessary, a silicone powder formed from the silicone elastomer, which is obtained by, for example, emulsifying dimethyl silicone elastomer into fine particles, can be contained. In this case, the silicone powder of 0.1-30 / zm is preferably used in combination with a silicone oil of 25 cst or less to prevent stickiness. The content of 05-5% gives the desired surface smooth feel and flexibility while maintaining the oil absorbency and water absorbency to the specified degree, and provides a highly economical formulation. .

[0027] These agents are preferably that have been coated at a ratio of 0. 46-0. 98g / m ² with respect to the application target surface. Because the drug coating amount of the coating target surface becomes like feel sticking to the skin without a smooth feel is less than 0. 46gZm ^2, the drug exceeds 0. 98gZm ² moves to the skin and removed from the tissue paper, The above range is preferable because it gives a sticky feel. The drug may be applied to both sides of the tissue paper, or may be applied to either one side. In the case of the latter, the application ratio to the surface to be applied is equal to the amount of drug applied per unit area of the tissue paper as a whole, whereas in the case of the former, the area of the surface to be applied is doubled. The amount of drug applied per unit area is twice the rate of application to the surface to be applied. When applying the chemical, an appropriate method such as spray application or roll application can be adopted.

Here, the form of the storage box will be supplementarily described. That is, as shown in FIG. 1, three pieces of paper were folded in a pop-up manner using the three pieces as a single thread and the longitudinal direction of the storage box 1 as a fold, and stored in the storage box 1 having an outlet at the top. The take-out opening at the top of the storage box 1 can also be taken out smoothly without breaking the tissue paper. As shown in the example of the drawing, a sheet 2 covering the window 1A, which is open at the top of the storage box 1, is adhered from the inner side of the box, as shown in the illustrated example. It has a take-out port X provided in this type of storage box provided with a slit 2A along. The length of the slit 2A is preferably 100 to 180 mm. It is preferable that the slit and the tissue paper are housed in a storage box so that the lateral direction is parallel.

[0029] On the other hand, it is desirable that the vertical paper strength during drying is 200 to 400 cN and the horizontal paper strength is 80 to 200 cN. In addition, the softness is 0.5-1.5 g, the water absorption of Klem specified in JIS P 8141 is 10 to 120 seconds, and the oil absorption of Klemm (water is sold according to the Klemm water absorption test specified in JIS P8141). Of salad oil (manufactured by Nisshin Oil Co., Ltd.) under the standard conditions specified in JIS P8111, except that the measurement time is 60 seconds and the paper flow is vertical (flow direction in the production line) In other words, the dimensions of the test piece were set vertically for 60 seconds, and the lower end of the paper was salad oil. The height of the salad oil that rises after 60 seconds is measured and the average value of 10 test pieces is measured. ) Is preferably 0.1 to 39.0 seconds.

[0030] For cosmetic tissue paper, it is particularly important that the surface is smooth.

It is desirable that the average deviation MMD of the coefficient of friction in the surface characteristics using a KES tester be 5.0 to 10.0.

[0031] For this surface property test, "Fractive Sense Tester KESSE" manufactured by Kato Tech Co., Ltd. can be used. During the measurement, as shown in Fig. 2, a friction wire consisting of a piano wire with a cross-sectional diameter of 0.5 mm and a contact surface length of 5 mm was moved while contacting a paper sample with a contact pressure of 10 g. Measure the coefficient of friction when moving the paper sample 2 cm at a speed of 0.1 cmZ seconds while applying a tension of 20 gZcm to the paper sample in the direction. In other words, the average deviation MMD of the coefficient of friction is the value obtained by dividing the area of the variation of the surface thickness when the friction element is moved by the movement distance (2 cm). Here, this MMD corresponds to smoothness.

Further, 4 mg of olive oil was uniformly applied to a 10 mm square contact plane made of artificial leather, and the entire contact plane was fixed on a horizontal measurement surface made of artificial leather with a contact pressure of 50 gfZcm ^2. The paper sample is brought into contact with the sample, and in this state, the paper sample is applied at a speed of 0.1 cmZ second in a direction orthogonal to the length direction or width direction of the contact plane while applying a tension of 20 gfZcm in the moving direction. The vertical and horizontal average of the surface characteristics expressed by the average deviation of the coefficient of friction when moving the horizontal measurement surface by 2 cm is preferably 0.50-2.00.

[0033] That is, as shown in Fig. 3 to Fig. 5, artificial leather (Sabulare: Asahi) is mounted on the base of a conventional MMD tester, for example, a friction tester (KES SE) manufactured by Kato Tec Co., Ltd. And the measurement terminal T is covered with artificial leather (Saburare: Asahi Kasei), and the measurement surface of the measurement terminal is covered with artificial leather (contact plane) with olive oil (BOSCO Etastra). Virgin oil: Nissin essential oil) 4 mg can be applied evenly and performed in the same manner as the MMD measurement procedure. In detail, the contact plane constituted by the artificial leather according to the present invention has a piano linear force with a cross-sectional diameter of 0.5 mm, a unit bulge having a curvature radius at the tip of 0.25 mm adjacent thereto, and MMD measurement with a continuous measurement surface with a total width of 10 mm and a measurement surface of approximately 10 mm square with the length of the measurement surface being 10 mm The fixed terminal can be formed by covering with the artificial leather. The terminal is coated with artificial leather so that the artificial leather is in close contact with the measuring surface of the terminal so that a contact plane of 10 mm square is formed, or the terminal leather is covered with a slight tension. This can be achieved by: When fixing the artificial leather to the terminal, hold it firmly so that the artificial leather and the internal terminal do not shift during measurement, that is, when the paper sample is moved, and the artificial leather does not deform the contact plane. It is important to. For fixing, for example, after covering the terminals so that the above-mentioned contact plane is formed, the parts that do not constitute the contact plane are firmly attached to a part that does not affect the measurement of the device with rubber bands or the like, such as a terminal support material. Fix it. Also, lay artificial leather on the base of the MMD testing machine and fix it with adhesive tape. At this time, it is important to fix the artificial leather firmly to the base so that it is not distorted during measurement. Moreover, the same artificial leather as the artificial leather constituting the contact plane is used as the artificial leather laid on the base. The paper sample is cut into a 10 cm square and used and fixed to a base on which artificial leather is spread. When measuring, press down on the paper sample with the sample holding weight (about 100g). Moreover, the force to make contact flat surface across composed of artificial leather load as 50g to the measurement terminal of the tester into contact with the paper sample at a contact pressure of 50GfZcm ² which, like the MMD measurements, disk This can be achieved by attaching a weight in the shape of a terminal to the upper part of the terminal. Of course, the way of fixing one end of the support (the end opposite to the direction of movement of the paper sample) is based on the MMD measurement. The measurement is performed three times in the vertical direction and three times in the horizontal direction of the paper sample, for a total of six measurements, and the measured value is the average of the six measurements. In addition, artificial leather and olive oil can be replaced with equivalent products.

[0034] Here, the surface characteristics are adjusted by pulp blending, calendering conditions, papermaking moisture, doctor blade angle, blade angle, adhesion / peeling strength tolerance, crepe ratio, addition and amount of surfactant, and the like. Is possible.

[0035] If necessary (usually unnecessary), another softener can be added. Examples of the softener include fatty acid ester softeners (U.S. Pat. No. 3,296,065), quaternary ammo-dum salt type cationic softeners (JP-A-48-22701), and urethane. Alcohols or salts thereof, or cations (JP-A-60-139897), non-cationic surfactants (JP-A-2-99690, JP-A-2-99691), polyphosphates (Japanese Unexamined Patent Publication No. 2-362 No. 88) and polysiloxanes (JP-A-2-224626 and JP-A-3-900). Particularly preferred softeners are quaternary ammonium salt-type cationic softeners and / or fatty acid ester-based softeners, all of which exhibit cationic properties. It is also possible to add paper strength agents (wet paper strength enhancers) such as amino resins such as urea formaldehyde resin and melamine formaldehyde resin, polyamide epichlorohydrin resin and dialdehyde starch.

Example

Various tests were performed on the product of the present invention (Examples 15 to 15) and a commercial product (Comparative Example). In Example 1-5, the pulp compounding ratio (NBKP: LBKP) was 50:50, the crepe ratio was 25.0%, the amount of sponge with sponge 8. Okg / t, the amount of sponge with carboxymethyl cellulose 0.8 kg / t, Softener (SFS 1002 (fatty acid ester-based compound, manufactured by Seiko PMC)) was used. A base paper made under the condition of 1.5 kg Zt was used. In Examples 115, a silicone powder emulsion chemical (PF1000, manufactured by Dow Koyung Silicone Toray Co., Ltd.) was applied to both front and back surfaces of a 3-ply tissue paper at a coating amount shown in Table 1 per one surface. The test results are also shown in Table 1.

As a result of a request for evaluation during makeup, except for the two monitors, all of the examples had better cushioning properties than the commercial products, and were smooth and soft to the touch during cleansing, and had excellent touch. It was evaluated that it was excellent in handling.

[0039] In addition, a monitor of 100 persons touched Examples 115 and Comparative Example 115, and requested a five-level evaluation of smoothness and stickiness. The result of the evaluation was that it had excellent sliding power compared to the others and had less stickiness. Regarding the smoothness, the normal (not smooth or rough) is set to 3, the smoothness is set to 4, the extremely smooth is set to 5, and the smooth is set to 2 And when it felt very rough, it was rated as 1. Regarding the feeling of stickiness, it was set to 3 when it was slightly sticky, 4 when it was hardly sticky, 5 when it was not sticky at all, 2 when it felt slightly sticky, and 1 when it was sticky. Was evaluated.
