Preferably on the effects of the present invention, the upper limit of the area which is the form it is a 8.00 mm ² or less, and more preferably not 2.00 mm ² or less, more preferably 0.80 mm ² or less.

The basis weight of the sheet constituting the toilet paper according to the present invention is preferably 18.0 to 22.0 g/m ² . More preferably, it is 19.0 to 21.0 g/m ² . The basis weight is according to JIS P 8124 (1998). INDUSTRIAL APPLICABILITY The toilet paper according to the present invention is produced by using, as a fiber material, pulp fiber having a known composition suitable for the toilet paper, and it is suitable that the toilet paper contains 50 to 100% by mass of virgin pulp.

The toilet roll 10 according to the present embodiment is manufactured so as to satisfy certain conditions (for example, the restoration rate and the lower limit value of the parameter corresponding to the restoration amount).

In the present embodiment, the paper thickness of the toilet paper 1 pulled out from the toilet roll 10 is measured according to ISO12625-3. Let Tr be the measured value of the paper thickness of this toilet paper 1, and let the area S occupied by the toilet paper on the cut surface orthogonal to the rotation axis C of the toilet roll 10 be the winding length L of the toilet paper wound on the toilet roll 10. When the calculated value obtained by dividing is Ti, the lower limit of the restored value obtained by dividing the measured value Tr by the calculated value Ti is 1.00 or more. The value obtained by dividing the measured value Tr by the calculated value Ti represents the restoring force (or the restoring rate or the restoring amount) of the toilet paper.

In order to achieve the effect of the present invention, the upper limit of the restoration value is preferably 1.80 or less, more preferably 1.45 or less. The paper thickness of the toilet paper 1 can be measured by various known measurement methods as long as it conforms to ISO12625-3.

As shown in FIG. 3, the area S occupied by the toilet paper is obtained by multiplying D/2 squared by π, where d is the diameter of the paper tube 14 and D is the winding diameter of the toilet roll 10. It is the value obtained by subtracting the square of d/2 multiplied by π.

If the value obtained by dividing the measured value Tr by the calculated value Ti is 1.00 or more, the softness is retained because the shape of the emboss is stable because of sufficient restoring force, but it is less than 1.00. , The embossed shape may be deformed due to lack of sufficient restoring force, and the embossed shape may be deformed, so that the softness may not be maintained.

Conventionally, the toilet paper pulled out from a widely used long roll has a possibility that its softness may be reduced due to its stronger winding hardness, as compared with that of a normal toilet roll which is not a long roll. Therefore, for example, Patent Document 1 discloses a sheet that forms a toilet paper by embossing to form voids between the sheets and improve softness.

By the way, the toilet paper that has been devised in the shape and structure of the constituent sheets has a thick paper thickness, and the roll-shaped toilet paper has a large winding diameter and the usable winding length is also limited. Tend. On the other hand, for example, in the case of toilet paper with embossing on the constituent sheets, if the force to wind the toilet paper around the paper tube (that is, the winding hardness) is increased in order to reduce the winding diameter of the toilet roll, the embossed shape will change. It may collapse and the softness may be impaired.

According to this aspect, since the shape and structure of the sheet forming the toilet paper are improved, the softness of the toilet paper can be maintained.

Further, since the roll diameter can be made compact while ensuring the softness of the toilet paper, it is possible to secure a usable roll length.

Furthermore, as will be described later, according to the first and second aspects of the present invention, it is possible to maintain water absorption and improve the feel to the touch.

As a suitable range for effectively exhibiting the effects of the present embodiment, the weight of the toilet roll 10 is 200 g to 250 g, the winding diameter D of the toilet roll 10 is 100 mm to 120 mm (more preferably 100 to 116 mm), and The winding length L is 75 m to 120 m (the lower limit is more preferably 100 m or more, the upper limit is more preferably 105 m or less), the diameter d of the paper tube 14 is 36 mm to 42 mm, and the measured value Tr of the paper thickness of the toilet paper 1 is 90 μm to 149 μm. Is. The thickness of the base paper before the embossing of the toilet paper 1 is measured according to ISO 12625-3 and is preferably 85 μm to 95 μm, like the measured value Tr of the thickness of the toilet paper 1.

The embossed pattern according to the present embodiment has a simple configuration in which a plurality of dot-shaped embossments are arranged in a diagonal lattice pattern, but as long as the effect of the present invention is exhibited, it is configured with a plurality of embossed patterns. May be.

<Second form>
FIG. 4 is a plan view for explaining a toilet paper pulled out from a toilet roll according to the second embodiment of the present invention, which is embossed. Unlike the first embodiment, this embodiment has an embossed portion 11'e in which a plurality of patterns in which a plurality of dot-shaped embosses e are arranged concentrically are arranged. Among the elements constituting the toilet roll according to this embodiment, those having the same function are given the same reference numerals as those in the first embodiment, and the description thereof will be omitted.

Similarly to the first embodiment, the paper thickness of the toilet paper 1′ pulled out from the toilet roll according to the present embodiment is also measured according to ISO12625-3 and is obtained by dividing the measured value Tr by the calculated value Ti. The value is 1.00 or more. With this configuration, as in the first embodiment, the shape and structure for improving the softness of the sheet constituting the toilet paper is maintained, so that the softness of the toilet paper can be maintained and the toilet paper can be maintained. Since it is possible to make the winding diameter compact while ensuring the softness of, the usable winding length can be secured.

<Method for manufacturing toilet roll according to the present invention>
The method for manufacturing a toilet roll of the present invention includes a step of making a slurry containing a fiber raw material to obtain a 1-ply toilet paper web.

Before the step of papermaking the slurry, a step of bleaching the fiber raw material may be included. As the bleaching agent used in the bleaching step, known bleaching agents such as oxygen bleaching agents and chlorine bleaching agents can be used.

The step of obtaining a one-ply toilet paper web includes the step of obtaining a slurry containing a fiber raw material. The step of obtaining a slurry preferably includes a step of beating the fiber raw material. In the beating step, for example, a beating process can be performed using a double disc refiner or the like. During the beating treatment, the softwood pulp and the hardwood pulp may be beaten individually, or may be beaten after being mixed.

The step of obtaining a one-ply toilet paper web includes a step of papermaking a slurry containing a fiber raw material. As a paper machine used in the step of making paper, for example, a suction breast former (cylinder type, fourdrinier type), twin wire former, cylinder former (C wrap, S lap), crescent former, etc. Can be mentioned.

In the paper making process, when the wet tensile strength in the length direction of the toilet paper is Tw and the wet tensile strength in the width direction is Yw, the paper is drawn out so that Tw/Yw is 1.30 or more and 2.60 or less. It is preferable to adjust the ratio of water flow speed/wire speed (jet wire ratio (J/W ratio)). The jet wire ratio is the ratio between the slurry supply speed and the wire traveling speed. When the jet wire ratio is greater than 1, the slurry supply speed is faster than the wire traveling speed. ". Further, when the jet wire ratio is 1 or less, the slurry supply speed is slower than the wire traveling speed, and this case is referred to as "pull formation".

In the papermaking process, a slurry containing a fiber raw material is supplied onto a mesh wire to form a thin layer of pulp. Then, while being transported to the press part, the moisture of the thin layer of pulp is drained to the bottom of the net, whereby the thin layer of pulp is dehydrated. Such a process may be called a dehydration process. In general, the wire is a ring made of metal or plastic mesh.

After the dewatering process, the wet paper web moves from the wire to the felt. The wet paper web is further mechanically squeezed by the pressure applied by the press roll through the felt. This may be called a pressing process or a water squeezing process.

In the papermaking step, for example, a method of forming a wet paper web as a uniform layer by making a pulp slurry obtained by mixing softwood pulp and hardwood pulp, or a softwood pulp layer and a hardwood pulp layer are combined to form one sheet. There is a method for forming the wet paper web, but any method may be adopted.

The paper making process includes a drying process after the water squeezing process. The drying step is preferably, for example, a step of blowing hot air toward the wet paper, or a step of pressing the wet paper onto the outer peripheral surface of the Yankee dryer. In the drying step with a Yankee dryer, it is preferable to perform a crepe treatment for forming wrinkles on the dust crepe by scraping the dried paper from the Yankee dryer with a doctor blade.

A calendering step may be included after the drying step. Examples of the calendering treatment include calendering treatment with two metal rolls, or soft calendering treatment with one of the two rolls being an elastic roll. When calendering is carried out, the linear pressure of the calender is preferably 0.1 kg/cm or more, more preferably 1.0 kg/cm or more, and even more preferably 2.0 kg/cm or more. Further, the linear pressure of the calendar is preferably 13 kg/cm or less, more preferably 12 kg/cm or less, and further preferably 11 kg/cm or less. By setting the linear pressure within the above range, it becomes easy to adjust the toilet paper web to a desired thickness and softness.

A base paper winding step is provided after the calendering step. In the base paper winding step, the toilet paper web (thin paper) finished through the above steps is wound to obtain one-ply base paper winding.

After the base paper winding step, a calendering step may be included. In this case, calendering can be performed while the unwound toilet paper web is unwound once. Examples of the calendering treatment include calendering treatment with two metal rolls, or soft calendering treatment with one of the two rolls being an elastic roll. When calendering is carried out, the linear pressure of the calender is preferably 0.1 kg/cm or more, more preferably 1.0 kg/cm, and even more preferably 2.0 kg/cm or more. Further, the linear pressure of the calendar is preferably 13 kg/cm or less, more preferably 12 kg/cm or less, and further preferably 11 kg/cm or less. By setting the linear pressure within the above range, it becomes easy to adjust the toilet paper web to a desired thickness and softness.

The embossing is performed by applying pressure with an embossing roll provided with embossing. In the drying process using a Yankee dryer, it is preferable to perform embossing so that the embossing roll contacts the toilet paper web surface on the side contacting the outer peripheral surface of the Yankee dryer. A recess is formed in the toilet paper web corresponding to the protrusion of the embossing roll. By changing the pushing amount or pushing pressure of the embossing roll, an embossed shape having a predetermined embossing height can be formed.

After the embossing process, another winding process is provided. In this winding step, a predetermined length of winding is performed so as to satisfy a predetermined product length. Winding is preferably performed so that the concave portion formed by the embossing process is on the outer peripheral side. This winding step includes a step of cutting the obtained winding into a predetermined width to obtain a toilet roll (toilet paper product).
