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 smoothness, moistness, softness, and volume are important for facial tissue paper. In order to produce a tissue paper product having smoothness, methods such as strengthening the strength of calendar processing and applying lotion chemicals are adopted (see, for example, Patent Documents 1 and 2).

Generally, lotion tissue paper coated with lotion chemicals is stored in a paper carton and pulled out from an outlet for use. Here, the lotion tissue paper has a better smoothness and moist feeling as the amount of the lotion chemical solution applied is larger, but on the other hand, the stiffness (rigidity and firmness) tends to decrease.

In addition, since the lotion tissue paper to which a large amount of lotion chemical solution was applied is soft, it was often torn when it was pulled out from the take-out port. In addition, after pulling out the lotion tissue paper from the paper carton, the next lotion tissue paper falls along the paper carton, making it difficult to remove the next lotion tissue paper, and the next set is in the paper carton. There was a problem that so-called "dropback" occurred. On the other hand, increasing the strength of the sheet solves these problems, but the lotion tissue paper tends to have a stiff feel. That is, in lotion tissue paper coated with a large amount of lotion chemical solution, it is difficult to achieve both the smoothness and moist feeling of the paper and the operability such as the ease of taking out the first sheet of lotion tissue paper. It was. Therefore, the present invention has been made in view of the above problems, and operations such as texture such as volume, smoothness, and moistness, ease of taking out the first sheet, and difficulty of dropback occur.

<Manufacturing method of lotion tissue paper>

[Manufacturing method of lotion tissue paper]
The lotion tissue paper 1 of the present invention can be produced in the order of (i) ply-up and calendar processing, (ii) application and storage of chemical solution, and (iii) interfolder processing, for example, as follows.

(I) Ply-up and calendar processing FIG. 2 shows an example of the machine winder 100.

Two primary rolls 11 are set on the machine winder 100, two plies are overlapped so that the Yankee surface is on the outside, and ply is applied. Calendar processing is performed by the calendar machine 101, and the secondary roll 12 To get.

(Ii) Application and storage of chemical solution The chemical solution is applied offline to the secondary raw fabric roll 12 after the calendar processing to obtain the tertiary raw fabric roll 13.

By applying the chemical solution to the secondary raw fabric roll 12 offline, the chemical solution can be permeated and fixed in the tertiary raw fabric roll 13 due to the storage period until processing compared to online. It is also possible to uniformly apply a larger amount of the drug to the secondary raw fabric roll 12 as compared with online.

As a method of applying the chemical solution to the secondary raw fabric roll 12 offline, generally used methods such as inkjet printing, flexographic printing, gravure printing, roll coating, spray coating and the like can be used, but flexographic printing can be used. It is preferable to have. With flexographic printing, a large amount of chemical solution can be applied and the amount of application can be easily adjusted as compared with other printing methods.

When applying the chemical solution to the secondary raw fabric roll 12, it is preferable to apply it to only one side (either the inner winding side or the outer winding side) of the secondary original fabric roll 12. As a result, when the third raw fabric roll 13 is wound up, the chemical solution applied to one side of the tertiary raw fabric roll 13 easily permeates the other surface in contact with the tertiary raw fabric roll 13, and as a result, the secondary raw material 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 in the tertiary raw fabric roll 13. In addition, the coating amount can be easily adjusted.

The period for storing the tertiary raw fabric roll 13 is preferably 7 days or more and 21 days or less from the day when the chemical solution is applied to the tertiary raw fabric roll 13, and more preferably 8 days or more and 20 days or less. It is preferable, and it is more preferably 10 days or more and 18 days or less. By setting the value within the above numerical range, it is assumed that wrinkles are less likely to occur on the sheet of the tertiary raw fabric roll 13 and the sheet of the tertiary raw fabric roll 13 is less likely to be broken during the interfolding processing described later. It is possible to improve the processing suitability.

As a method for storing the tertiary original roll 13, it is preferable to use the storage device described in Japanese Patent No. 5933384. FIG. 3 is a diagram showing an example of a storage device for storing the tertiary original roll 13. For example, the wrapping film 111 is wound tightly around the outer peripheral surface 13a of the tertiary raw fabric roll 13 coated with the chemical solution, and the tightening band 112 for tightening the outer peripheral surface 13a is wrapped around the wrapping film 111 to form the tertiary original. It is preferable that the tertiary original roll 13 is stored on the roll holder 113 on which the anti-roll 13 is placed by installing the winding core horizontally with respect to the installation surface 117. According to this configuration, the outer peripheral surface 13a of the tertiary raw fabric roll 13 is tightened not only by the wrapping film 111 but also by the tightening band 112, so that the third original fabric is compared with the case where it is simply wrapped with the wrapping film 111. The morphological stability of the roll 13 is significantly improved. Therefore, the deformation of the tertiary raw fabric roll 13 after the application of the chemical solution can be effectively suppressed.

The roll holder 113 has a receiving surface 114 that receives and holds the lower portion of the tertiary raw fabric roll 13, and the receiving surface 114 is formed on a curved surface along the outer peripheral surface 13a of the tertiary original fabric roll 13. Is preferable. According to this configuration, the lower portion of the tertiary raw fabric roll 13, which is most easily deformed by its own weight, is stably received and held by the curved receiving surface 114, so that the lower portion of the tertiary original fabric roll 13 is held. Deformation can be prevented. Thereby, the deformation of the tertiary raw fabric roll 13 can be suppressed more effectively.

The roll holder 113 has a support portion 115 having a receiving surface 114 on the upper surface thereof, and the support portion 115 is composed of a core material and a laminated plate made of paper in which a face material for preventing warpage of the core material is laminated. It is preferable that the upper surface of the support portion 115 is provided with a face material forming the receiving surface 114, while the lower surface of the support portion 115 is not provided with a face material. According to this configuration, by forming the support portion 115 with a light laminated plate made of paper, the weight of the roll holder 113 can be reduced and the handleability can be improved. Further, since there is no face material on the lower surface of the support portion 115 that supports the tertiary raw fabric roll 13, the support portion 115 bends satisfactorily when a load is received from the tertiary raw fabric roll 13. On the other hand, if there is a face material on the lower surface of the support portion 115, 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, since the lower surface of the support portion 115 without the face material is curved satisfactorily, the tertiary raw fabric roll 13 can be stored more stably. The roll holder 113 may have a leg portion 116 that floats and supports the support portion 115 from the installation surface 117.

(Iii) Interfolder processing A lotion tissue paper 1 is obtained by processing a sheet of a tertiary raw fabric roll 13 to which a chemical solution is applied and stored for a predetermined period of time.

The processing of the tertiary raw fabric roll 13 can be performed by known interfolding processing, and pop-up is performed by alternately laminating and processing each sheet of each tertiary raw fabric roll 13 while folding and crossing them. It is preferable to obtain a lotion tissue paper that can be taken out in a formula. Each sheet of each tertiary roll 13 may be folded in a V-shape, a Z-shape, or the like at the center as long as it can be taken out in a pop-up manner.

Examples of the interfolder include a rotary type interfolder and a multi-stand type interfolder, but it is preferable to use the rotary type interfolder 120. Lotion tissue paper has lower strength than tissue paper to which lotion is not applied, so it is better to process it with rotary interfolder 120, which does not require much tension compared to multi-stand interfolder and has a slower processing speed. It's hard to do.

Specifically, as shown in FIG. 4, two tertiary raw fabric rolls 13 are set in the rotary type interfolder 120, folded by the rotary type interfolder processing machine 121, and the lotion tissue paper laminate 14 is used. Is manufactured and contained in the film pack 20. Further, as shown in FIG. 4, it is preferable to compress the laminated body 14 before inserting the laminated body 14 into the film pack 20. In this processing, a compression device 123 is provided directly above the transport device 122 on which the laminate 14 is placed and conveyed to the film pack 20, and the laminate 14 is compressed by passing the laminate 14 between the two. ing. When the laminate 14 is compressed in this way, the lotion tissue paper can be made bulky before the compression treatment and can be adjusted to a predetermined height dimension by the subsequent compression treatment, so that the chemical solution is applied to the base paper that has been excessively compressed in advance. It becomes softer than when you do it.
<Example>

Hereinafter, the present invention will be described in detail with reference to examples. The present invention is not limited to the examples shown below.

<Examples 1 to 21, Comparative Examples 1 to 10>
As wood pulp, a base paper was made from NBKP and LBKP having the pulp composition (mass%) shown in Tables 1 to 3, and then the base paper was subjected to calendar and ply-up treatment. Next, the lotion chemicals shown in Tables 1 to 3 are applied offline to this base paper with a gravure coating device, and then a laminate of lotion tissue paper is formed with a rotary interfolder, and further into a film pack. Contained. In Tables 1 to 3, the polyhydric alcohol is glycerin, and the oily component is a mixture of amino-modified silicone oil and shea butter. For the obtained lotion tissue paper, TS750, TS7, D, and the chemical content in the paper were measured, and the feeling of use, volume, moistness, smoothness, ease of use (dropback frequency), and strength of the film pack were measured. (Difficulty of tearing), Difficulty of tearing lotion tissue paper at the time of removal, softness, firmness (how the next lotion tissue paper stands when the lotion tissue paper is taken out from the carton), frequency of film pack replacement, The appearance of the film pack was evaluated on a 5-point scale.

Sheet basis weight: Measured based on JIS P 8124 and converted per sheet.
Paper thickness: Measured using a thickness gauge (dial thickness gauge "PEACOCK" manufactured by Ozaki Seisakusho). The measurement conditions were a measuring load of 250 gf, a stylus diameter of 30 mm, a sample was placed between the stylus and the measuring table, and a gauge was read when the stylus was lowered at a speed of 1 mm or less per second. In addition, one measurement was performed by stacking 10 sheets of 1 ply, and the measurement was repeated 10 times to average the measurement results.
Film thickness: Measured based on JIS Z 1702.
The basis weight, paper thickness, TSA, film pack thickness, and film pack height are measured in an equilibrium state under the temperature and humidity conditions (23 ± 1 ° C., 50 ± 2% RH) specified in JIS P 8111. I went after holding it in.

The following evaluations were made by 20 monitors.
Usability: The usability (stiffness of the paper, penetration of moisture, etc.) when the lotion tissue paper taken out from the film pack was unfolded and used (blowing the nose, wiping off dirt, etc.) was comprehensively evaluated.
Volume feeling: The volume feeling when the lotion tissue paper taken out from the film pack was unfolded and held in the hand, and the paper thickness of the product were evaluated.
Moist feeling: The moist feeling when the lotion tissue paper taken out from the film pack was unfolded and held in the hand was evaluated.
Smoothness: The smoothness of the lotion tissue paper that came into contact with the skin when the lotion tissue paper taken out of the film pack was unfolded and used (blowing the nose) was evaluated.
Ease of use (dropback frequency): The frequency of dropback when using lotion tissue paper was evaluated.
Film pack strength (difficulty in tearing): The resistance to tearing of the film pack was evaluated.
Difficulty of tearing lotion tissue at the time of taking out: The difficulty of tearing of lotion tissue paper at the time of taking out the lotion tissue paper from the film pack was evaluated.
Softness: The lotion tissue paper taken out from the carton was unfolded and the softness when held in the hand was evaluated.
Firmness: The standing condition of the next lotion tissue paper when the lotion tissue paper was taken out from the carton was evaluated.
Film pack replacement frequency: The film pack replacement frequency was evaluated.
Film pack appearance: We evaluated the appearance of the film pack.
In the evaluation, the product equivalent to the conventional product was rated as "3", slightly superior to this was rated as "4", and superior was rated as "5". Similarly, "2" was inferior to "3", and "1" was significantly inferior to "3". If the evaluation is 3 to 5, there is no problem.

From Tables 1 to 3, according to the present invention, the feeling of use, the feeling of volume, the feeling of moistness, the smoothness, the ease of use, the strength of the film pack, and the resistance to tearing of the lotion tissue paper at the time of taking out are all good. It can be seen that the lotion tissue paper was obtained.
