Description

The present invention relates to a lotion tissue paper consisting of a two-ply sheet coated with a chemical solution.

Conventionally, it has been pointed out that moist feeling, smoothness, softness and voluminous feel are important for facial tissue paper. In order to produce tissue paper having smoothness, moistness and softness, techniques such as application of lotion chemicals are employed (see, for example, Patent Documents 1 and 2).

Here, when the process of applying the chemical lotion is included in the manufacture of the tissue paper, the process of applying the chemical lotion to the sheet of the original roll is performed online in the process of processing the original roll into the tissue paper and a series of processes. techniques are commonly employed (see, for example, US Pat.

JP-A-7-109693 JP-A-9-296389 JP 2012-34869 A

On the other hand, if the chemical lotion is applied to the raw roll sheet in a separate process, not online, but off-line, the chemical lotion can permeate the raw roll until it is processed into tissue paper. Therefore, even if the amount of the chemical lotion applied is large, the chemical lotion permeates the raw fabric roll and is fixed, so it is possible to obtain a tissue paper with a high content of the chemical lotion. Softness can be improved.

The ratio obtained by dividing (B) by (A) is represented by (%), with the mass (B) (g) obtained as a numerator. In addition, the calculation of (B) can be quantified by, for example, extracting lotion tissue paper with acetone/ethanol.
(Drug content) = (B) ÷ (A) x 100 (%)

By setting the chemical content within the above range, the moist feeling, smoothness and softness of the touch of the lotion tissue paper are improved.

[Manufacturing method of lotion tissue paper]
The lotion tissue paper of the present invention can be manufactured, for example, in the order of (i) ply-up and calendering, (ii) application and storage of a chemical solution, and (iii) interfolding, as follows.

(i) Ply-up and calendering FIG. 1 shows an example of a machine winder 100 .

Two primary fabric rolls 11 are set in a machine winder 100, and two plies are piled up so that the Yankee side faces outward. get

The basis weight of the sheet of the second raw fabric roll 12 after calendering is preferably 8 g/m ^{2 or more and 17 g/m 2} or less, and 9 g/m ^{2 or} more and 16 g/m ² or less per ply. more preferably 10 g/m ² or more and 15 g/m ² or less. In addition, the sheet thickness of the second raw fabric roll 12 after calendering is preferably 0.50 mm/10 sheets or more and 0.90 mm/10 sheets or less per ply, and 0.55 mm/10 sheets. It is more preferably 0.85 mm/10 sheets or less, and even more preferably 0.60 mm/10 sheets or more and 0.80 mm/10 sheets or less. In the application and storage of the chemical solution, which will be described later, the chemical solution is applied to the second raw roll 12, so the basis weight and paper thickness can be lower than those of the lotion tissue paper obtained by interfolding. preferable.

Also, the amount of change Δt between the thickness per ply of the sheet on the primary roll 11 before calendering and the thickness per ply of the sheet on the secondary roll 12 after calendering is , 0.08 mm/10 sheets or more and 0.25 mm/10 sheets or less, and more preferably 0.10 mm/10 sheets or more and 0.22 mm/10 sheets or less. By adjusting the value of Δt, the paper thickness after calendering and the paper thickness of the product can be well adjusted, and softness and voluminousness can be well maintained.

(ii) Application and storage of chemical solution A chemical solution is applied off-line to the second material roll 12 after calendering to obtain the third material roll 13 .

By applying the chemical solution to the second material roll 12 off-line, compared to online, the chemical solution can be permeated and fixed to the third material roll 13 because of the storage period until processing. It is also possible to uniformly apply a larger amount of chemicals to the secondary material roll 12 than online.

As for the method of applying the chemical solution to the second raw fabric roll 12, if it is offline, a generally used method such as inkjet printing, flexographic printing, gravure printing, roll coating, spray coating, etc. can be used. Printing is preferred. Compared with other printing methods, flexographic printing allows a large amount of chemical solution to be applied, and the application amount can be easily adjusted.

When applying the chemical solution to the secondary film roll 12, it is preferable to apply the chemical to only one side of the secondary film roll 12 (either the inner winding side or the outer winding side). As a result, when the tertiary roll 13 is wound, the chemical solution applied to one side of the tertiary roll 13 easily permeates the other side in contact with the surface, resulting in the secondary roll 13. Rather than applying the chemical solution to both the outer winding side and the inner winding side of the anti-roll 12, the chemical solution can be uniformly permeated and fixed to the third raw fabric roll 13. - 特許庁In addition, it is possible to make it easier to adjust the coating amount.

The period for storing the third raw roll 13 is 6 days or more and 22 days or less, preferably 8 days or more and 20 days or less, and 10 days, from the day when the chemical solution is applied to the third raw roll 13. More preferably, it is 18 days or less. By setting the value within the above numerical range, wrinkles are less likely to occur in the sheet of the third original roll 13 and breakage of the sheet of the third original roll 13 is reduced during interfolder processing, which will be described later. It is possible to improve the processability.

As for the method for storing the third raw fabric roll 13, it is preferable to use the storage device described in Japanese Patent No. 5933384. FIG. 2 is a diagram showing an example of a storage device that stores the third original roll 13. As shown in FIG. For example, the wrapping film 111 is tightly wound around the outer peripheral surface 13a of the tertiary roll 13 to which the chemical solution is applied, and the tightening band 112 that tightens the outer peripheral surface 13a is wound on the wrapping film 111, and the third raw roll 13 is wound. It is preferable to set the core of the third original fabric roll 13 in the horizontal direction with respect to the setting surface 117 and store it on the roll holder 113 on which the anti-roll 13 is placed. According to this configuration, the outer peripheral surface 13 a of the third roll 13 is tightened by the tightening band 112 in addition to the wrapping film 111 . The shape stability of the roll 13 is remarkably improved. Therefore, it is possible to effectively suppress the deformation of the third material roll 13 after applying the chemical solution.

The roll holder 113 has a receiving surface 114 for receiving and holding the lower part of the third original fabric roll 13. The receiving surface 114 is formed into a curved surface along the outer peripheral surface 13a of the third original fabric roll 13. preferably. According to this configuration, the curved receiving surface 114 stably receives and holds the lower portion of the tertiary roll 13, which is most likely to be deformed by its own weight. Deformation can be prevented. As a result, deformation of the third original fabric roll 13 can be suppressed more effectively.

The roll holder 113 has a support portion 115 having a receiving surface 114 on its upper surface. It is preferable that a face member forming the receiving surface 114 is provided on the upper surface of the support portion 115 while no face member is provided on the lower surface of the support portion 115 . According to this configuration, the weight of the roll holder 113 can be reduced and the handleability can be improved by configuring the supporting portion 115 with a light laminated plate made of paper. Further, since there is no surface material on the lower surface of the support portion 115 that supports the third film roll 13, the support portion 115 bends well when a load is applied from the third film roll 13. FIG. On the other hand, if the lower surface of the support portion 115 has a surface material, the rigidity of the lower surface of the support portion 115 is increased, so that the deformation of the lower surface of the support portion 115 is suppressed. In this respect, according to the above configuration, the lower surface of the support portion 115 having no face material is well curved, so that the tertiary web roll 13 can be stored more stably. Note that the roll holder 113 may have a leg portion 116 that supports the support portion 115 by floating it from the installation surface 117 .

(iii) Interfolder processing A lotion tissue paper is obtained by processing the sheet of the third raw fabric roll 13 that has been applied with a chemical solution and stored for a predetermined period of time.

The processing of the third raw fabric roll 13 can be performed by a known interfolder processing machine. It is preferable to have a pop-up removable lotion tissue paper. Each sheet of each tertiary material roll 13 may be folded at the center by V-folding, Z-folding, or the like, as long as it can be taken out in a pop-up manner.

As the interfolder processing machine, a multi-stand interfolder processing machine, a rotary interfolder processing machine, or the like can be used, and the multi-stand interfolder processing machine 120 is preferably used. In general, a multi-stand interfolder has a larger installation area than a rotary interfolder, but it can produce a large amount of boxed tissue paper at a higher speed than a rotary interfolder. Therefore, the lotion tissue paper of the present invention can be mass-produced. Here, in the multi-stand type, for example, 30 sets or more of the tertiary rolls 13 are prepared, and each folding mechanism unit 121 described later performs interfolding, so lotion is applied to each roll and processed. There is a storage period until If the storage period is short, the lotion tissue paper tends to wrinkle, and if the storage period is long, the raw roll tends to break, so it may be difficult to improve the processability of the raw roll. . Therefore, in the production of lotion tissue paper, a rotary interfolder is often used. In this respect, according to the method for producing lotion tissue paper of the present invention, the storage period can be adjusted within a favorable range as described above, and the storage method can be improved. Therefore, even with the multi-stand type, the original roll can be stored satisfactorily before processing, and mass production can be performed.

FIG. 3 is a drawing showing how the continuous sheet is folded in the folding mechanism section 121 of the multi-stand interfolder processing machine 120. As shown in FIG. A folding mechanism unit 121 that folds a pair of two continuous sheets (first continuous sheet 13b and second continuous sheet 13c) into a V-shaped cross section or a Z-shaped cross section so as to sandwich each other's ends. A continuous laminate 13d of lotion tissue papers with a folded width A of 85 mm or more and 115 mm or less is obtained by a multi-stand interfolder 120 having 100 or more and 200 or less sets. Here, the number of folding mechanism units 121 represents the number of times the lotion tissue paper is stacked. When 100 sets are provided, 200 plies of lotion tissue paper are laminated. In addition, two folding plates (a first folding plate 122a and a second folding plate 122b) are provided in the folding mechanism portion 121 of each set. The first folding plate 122 a is composed of a metal plate having a J-shaped cross section, and one end in the width direction thereof is fixed to the back stand frame 123 of the multi-stand interfolder processing machine 120 . The second folding plate 122b is provided on the downstream side of the first folding plate 122a and is composed of a substantially trapezoidal flat metal plate. It is fixed to the back stand frame 123 of the multi-stand interfolder processing machine 120 .

Hereinafter, the present invention will be described in detail with reference to examples. It should be noted that the present invention is by no means limited to the examples shown below.

<Examples 1 to 13, Comparative Examples 1 to 6 >
Base papers having the properties shown in Tables 1 and 2 were made from NBKP and LBKP having pulp compositions (% by mass) shown in Tables 1 and 2 as wood pulp to obtain primary raw rolls. Next, two primary rolls were set in a machine winder, calendered, and two plies were laminated to obtain a secondary roll. Next, the lotion chemicals shown in Tables 1 and 2 are applied off-line to the second raw roll with a flexo coating device to obtain the third raw roll, which is described in Japanese Patent No. 5933384. It was stored for the periods shown in Tables 1 and 2 in a storage apparatus provided with a storage device, and a laminate of lotion tissue paper was formed using a multi-stand interfolder processing machine. In Tables 1 and 2, the polyhydric alcohol is glycerin, and the oil component is a mixture of amino-modified silicone oil and shea butter. The resulting lotion tissue paper was measured for TS7, TS750, D, the content of oily components in the paper, and the content of chemicals in the paper. The feel, workability (frequency of occurrence of paper breaks), and frequency of occurrence of product wrinkles were evaluated on a 5-point scale.

Basis weight of sheet: Measured based on JIS P 8124 and converted to one ply of sheet.
Paper thickness: Measured using a thickness gauge (dial thickness gauge "PEACOCK" manufactured by Ozaki Seisakusho). The measurement conditions were a measurement load of 250 gf and a probe diameter of 30 mm. In addition, one measurement was performed by stacking 10 samples, and the measurement was repeated 10 times, and the measurement results were averaged.
The grammage, paper thickness, and TSA were measured after holding in equilibrium under the temperature and humidity conditions specified in JIS P 8111 (23±1° C., 50±2% RH). Further, the grammage and paper thickness in Tables 1 and 2 are obtained by applying a chemical solution.

The following sensory evaluation was performed by 20 monitors.
Feeling of use: The feeling of use (stiffness of paper, permeation of moisture, etc.) when the tissue paper taken out of the carton was unfolded and used (blowing one's nose, wiping off dirt, etc.) was evaluated comprehensively.
Voluminous feeling: The voluminous feeling and the paper thickness of the product were evaluated when the tissue paper taken out of the carton was unrolled and held in the hand.
Moist feeling: The moist feeling was evaluated when the tissue paper taken out of the carton was unrolled and held in the hand.
Softness: The softness was evaluated when the tissue paper taken out of the carton was unrolled and held in the hand.
Smoothness: When the tissue paper taken out of the carton was unfolded and used (blown the nose), the smoothness of the tissue touching the skin was evaluated.
Firm feeling: When the tissue paper was taken out of the carton, the standing condition of the next tissue paper was evaluated.
The evaluation was given as "3" when equivalent to the conventional product, "4" when slightly superior, and "5" when superior. Similarly, "2" was given when it was inferior to "3", and "1" was given when it was significantly worse. A rating of 3 to 5 is fine.
