Description

Roll toilet paper and manufacturing method of roll toilet paper

The present invention relates to a roll of toilet paper in which a strip-shaped toilet paper is wound around a paper tube, and a method of manufacturing such a roll of toilet paper.

In toilet spaces, odors originating from urine and feces are sometimes generated, so deodorization technologies for toilet spaces and odor alleviation technologies using aroma have been proposed.

For example, a technique is known in which a deodorant such as paradichlorobenzene, to which a fragrance component is added, is applied to the inner surface of a paper tube of toilet paper rolls commonly used in toilet spaces (Patent Document 1 below). In addition, there is known a technique in which a deodorant that exhibits a deodorizing effect through neutralization is impregnated into a paper tube by utilizing the alkaline properties of ammonia, which is the cause of toilet odor, that is, the odor of urine (below). Patent document 2). Furthermore, there is also known a technique in which the aroma attached to paper tubes and toilet paper is mixed with the odor of methyl mercaptan and hydrogen sulfide, which are the cause of feces odor, thereby blending the odor or masking the odor. And the odor is alleviated (Patent Document 3 mentioned below). [Prior technical literature] (patent document)

Patent Document 1: Japanese Publication No. 56-111890. Patent Document 2: Japanese Patent Application Publication No. 2017-56210. Patent Document 3: Japanese Patent Application Publication No. 2017-176571.

[Problem to be solved by the invention] The main components of the stench in the toilet space, that is, the odor of feces, are methylmercaptan, trimethylamine, and hydrogen sulfide, and the main component of the odor of urine is ammonia. The paradichlorobenzene disclosed in the above-mentioned Patent Document 1 is excellent in the deodorizing effect of masking urine odor derived from ammonia gas, but is not necessarily effective against the components causing feces odor. In addition, the technology disclosed in Patent Document 2 is not necessarily effective against acidic feces odor components such as hydrogen sulfide. Furthermore, although the technology disclosed in Patent Document 3 is excellent in masking methyl mercaptan and hydrogen sulfide, it is not necessarily effective in deodorizing ammonia odor. In addition, the technology of Patent Document 1 and Patent Document 3 is a technology that masks bad odors with aroma, and it is difficult to create unscented products with undesirable aroma. Furthermore, in recent years, due to the impact of the new coronavirus infectious disease (COVID-19), there has been an increase in people going out to self-isolate, working from home, studying at home, etc., and people are spending more time at home. Although this will vary from person to person, for those who have begun to care about the past The increase in the number of people who do not pay attention to the odor in their own homes requires a more effective deodorization technology for toilet spaces, especially odors such as feces odor and urine odor in toilet spaces that are increasingly used.

Therefore, the main problem to be solved by the present invention is to provide a roll toilet paper and a manufacturing method thereof, which are the main components of urine odor and feces odor, namely methyl mercaptan, trimethylamine, hydrogen sulfide, Ammonia gas has an excellent deodorizing effect, and it can also be made fragrance-free. [Technical means to solve problems]

The first means of the present invention to solve the above problems is a toilet paper roll, characterized in that a strip-shaped toilet paper is wound around a paper tube, and, This toilet paper roll contains a tannin-based deodorant, a catechin-based deodorant, and a silver-loaded zeolite.

The second means is the toilet paper roll as described in the first means, wherein a catechin-based deodorant, a tannin-based deodorant, and a silver-loaded zeolite are applied to the paper tube, and the applied portions are No acrylic resin is added.

The third means is the toilet paper roll according to the first or second means, wherein the catechin-based deodorant, the tannin-based deodorant, and the silver-supported zeolite are adhered to the inner peripheral surface of the paper tube. The fibers of the paper tube base paper may be held in the gaps between the fibers.

The fourth means is a manufacturing method of toilet paper rolls, characterized by manufacturing toilet paper rolls in which strip-shaped toilet paper is wound around a paper tube. The manufacturing method includes: a mixing step of mixing a liquid agent and a catechin-based toilet paper. A deodorant, a tannin-based deodorant and a silver-loaded zeolite are mixed, and the liquid agent contains diethylene glycol monoethyl ether and isopropyl alcohol; the imparting step is to mix the mixed liquid agent at 3.0 to 6.0 g/m ² conditions are applied to paper tube base paper with a paper thickness of 100 to 400 μm and a basis weight of 130 to 200 g/ ^m2 , thereby imparting catechin-based deodorants, tannin-based deodorants, and silver to the paper tube base paper. carrying zeolite; and, a step of manufacturing roll toilet paper by using the paper tube base paper and making the aforementioned imparted surface into the inner surface of the paper tube. [Effects of the invention]

As mentioned above, according to the present invention, a toilet paper roll and a manufacturing method thereof can be provided, which toilet paper can deodorize the main components of urine odor and feces odor, namely methyl mercaptan, trimethylamine, hydrogen sulfide, and ammonia. The effect is excellent and can be set to be fragrance-free.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

"Toilet paper roll" As shown in FIG. 1 , the toilet paper roll of this embodiment has a strip-shaped toilet paper S3 wound around a paper tube 11 . The size of toilet paper is not limited, but it is expected that the width L1 is 100 to 120 mm, the diameter L2 is 100 to 120 mm, the winding length (total length of toilet paper) is 18 to 80 m, and the paper tube diameter is 35 to 50 mm. .

Toilet paper S3 can have a basis weight of 11.0 to 25.0 g/m ² per layer, a paper thickness of 100 to 180 μm, and 1 to 4 layers.

In addition, the basis weight is measured in accordance with the basis weight measurement method of Japanese Industrial Standards JIS P 8124 (1998), and the paper thickness is the average value of five measurements. This measurement is based on the Japanese Industrial Standards JIS P 8111 (1998). ) conditions, and then use a dial thickness gauge (thickness measuring instrument) "PEACOCK G type" (manufactured by Ozaki Seisakusho) under the same conditions.

This toilet paper is characterized by being provided with a catechin-based deodorant, a tannin-based deodorant, and a silver-supported zeolite. Deodorants other than these are not given. Among polyphenol-based deodorants known to selectively react with substances that cause odors in toilet spaces such as ammonia to deodorize, tannin-based deodorants are particularly used. And catechin-based deodorants, using silver-loaded zeolite instead of just zeolite that adsorbs volatile components to porous substances, can extremely effectively reduce the odor generated by methylmercaptan, trimethylamine, hydrogen sulfide, and ammonia gas. The odor is significantly and quickly reduced, making it an excellent deodorizer for urine odor and feces odor. In addition, the catechin-based deodorant, the tannin-based deodorant, and the silver-loaded zeolite are all odorless or almost odorless, so it is possible to produce a toilet paper roll that is substantially odorless.

The catechin-based deodorant contains at least one kind of catechin and a catechin derivative, and has at least one kind of a catechin and a catechin derivative as a main active ingredient. Examples of catechins include catechin, epicatechin, epigallocatechin, epicatechin gallate, and epigallocatechin gallate. In addition, it may contain plural types of catechins such as tea catechins. In addition, plant-extracted catechins such as tea catechins may also be used. At least one of catechins and catechin derivatives has bactericidal properties. Therefore, the proliferation of bacteria and the like that decompose urine and produce ammonia gas can be suppressed in the toilet space. In addition, plant-extracted catechins can give users a sense of security derived from natural ingredients.

The tannin-based deodorant contains at least one kind of tannin and a tannin derivative, and is one in which at least one kind of a tannin and a tannin derivative is used as a main active ingredient. Tannin and tannin derivatives have a large molecular weight and retain a large amount of phenolic hydroxyl groups that exert a deodorizing function in the molecules. Therefore, they have excellent reactivity with ammonia gas, which is one of the main components of odor in toilet spaces. And it can exert excellent deodorizing function in the toilet space. Tannins and tannin derivatives may be condensed or hydrolyzed. These may also be mixed. In addition, the tannin may contain multiple types of tannins such as black tea-derived tannins, persimmon tannins, and persimmon tannin derivatives. Tannins can be derived from plants, which can give users a sense of security. A particularly preferred tannin-based deodorant is one containing at least one of persimmon-derived persimmon tannins and persimmon tannin derivatives as a main component. Persimmon tannins and persimmon tannin derivatives derived from persimmons have particularly large molecular weights and excellent deodorizing effects. Furthermore, in the present invention, catechins and tannins are distinguished. Furthermore, tannic acid is contained in tannins.

Regarding the silver-supported zeolite, the form of silver in the silver-supported zeolite is silver ions, silver clusters, and metallic silver, and is a form containing at least silver ions. In addition, the silver-supported zeolite may support substances other than silver on the zeolite. In addition, the silver-supported zeolite in the present invention is not limited, and examples thereof include Zeomic (manufactured by Sinanen Zeomic Co., Ltd.), Zaobaset AG-30N (manufactured by Yamato Chemical Industry Co., Ltd.), and the like. In particular, it is suitable for the silver-supported zeolite contained in Zaobaset AG-30N (manufactured by Daiwa Chemical Industry Co., Ltd.).

The contents of the catechin-based deodorant, tannin-based deodorant, and silver-supported zeolite in toilet paper are not limited. Just adjust it appropriately according to the types of catechins, tannins and silver-loaded zeolite.

The portion where the catechin-based deodorant, the tannin-based deodorant and the silver-loaded zeolite are applied in the toilet paper roll 10 is not necessarily limited, as long as it is applied to at least one of the paper tube 11 and the toilet paper S3 . The respective imparting parts of the catechin-based deodorant, the tannin-based deodorant, and the silver-supported zeolite may be different. Preferably, the catechin-based deodorant, the tannin-based deodorant and the silver-loaded zeolite are all added to the paper tube 11 to make the roll hygienic. The paper tube 11 is the last part that remains even if the toilet paper S3 is used, so it is easy to continue the deodorizing effect until the toilet paper S3 is used up.

In the toilet paper roll 10 , when the catechin-based deodorant, the tannin-based deodorant, and the silver-loaded zeolite are applied to the paper tube 11 , it is desirable that the applied portions are not Where acrylic resin has been applied. Acrylic resin makes it difficult for catechin-based deodorants, tannin-based deodorants, and silver-loaded zeolites to properly adhere to paper tubes. In addition, each deodorant may be coated and the breathability may be reduced.

As a form in which the catechin-based deodorant, the tannin-based deodorant, and the silver-supported zeolite are provided, the following form is particularly preferred as shown in Figure 2, in which the catechin-based deodorant, the tannin-based deodorant, and the silver-supported zeolite are provided. The deodorant and the silver-loaded zeolite adhere to the fibers of the paper tube base paper 12 constituting the inner peripheral surface of the paper tube 11 or are held in the gaps between the fibers. That is, it has the form of a portion 40 in which a catechin-based deodorant and a tannin-based deodorant are present in the thickness direction of the paper tube 11 from the inner circumferential surface side of the paper tube toward the outer circumferential surface side of the paper tube. agent, silver loaded zeolite. The inner circumferential surface of the paper tube 11 is different from the outer circumferential surface formed by winding several layers of toilet paper S3. It is exposed to the atmosphere in the toilet space, and therefore has an increased chance of contact with malodorous components, thereby achieving a better deodorizing effect. . In addition, especially at the time of application, the catechin-based deodorant and the tannin-based deodorant are in the form of solutions, and the silver-supported zeolite is in the form of individual dispersions. Therefore, for example, if they are separately or mixed and applied by When applied to the inner circumferential surface of the paper tube 11, the catechin-based deodorant, tannin-based deodorant, and silver-loaded zeolite penetrate from the inner circumferential surface of the paper tube toward the outer circumferential surface in the thickness direction. It becomes a form in which the fibers of the paper tube base paper are attached or held in the gaps between the fibers. In this form, the detachment of catechin-based deodorant, tannin-based deodorant, and silver-loaded zeolite from the inner circumferential surface of the paper tube is reduced. For example, when toilet paper S3 is extracted, even if the inner circumferential surface of the paper tube is Even if it is rubbed against a part of the toilet paper holder, the catechin-based deodorant, tannin-based deodorant, and silver-loaded zeolite will not be separated from the inner peripheral surface of the paper tube, and the deodorizing effect will still be fully maintained. . In addition, the inner surface of the paper tube can fully ensure contact with the odor components floating in the toilet space, thereby exerting an excellent deodorizing function.

The paper tube 11 of the toilet paper roll 10 is preferably made of paper tube base paper having a paper thickness of 100 to 400 μm and a basis weight of 130 to 200 g/m ² . In the paper tube base paper with such paper thickness and basis weight, the fiber density will be appropriate, and the catechin-based deodorant, tannin-based deodorant, and silver-loaded zeolite will easily adhere to the paper tube base paper 12 The fibers may be held in the spaces between the fibers. Therefore, in particular, it penetrates from the inner circumferential surface of the paper tube 11 toward the outer circumferential surface direction in the thickness direction, becomes easy to adhere to the fibers of the paper tube base paper, or is held in the gaps between the fibers, and can pass through the paper tube. The inner surface effectively comes into contact with malodorous components and becomes able to exert an excellent deodorizing function.

Furthermore, the paper tube base paper 12 constituting the paper tube 11 is preferably in the following form: a density of 0.2 to 1.8 g/cm ³ , a tensile strength (vertical) of 4.0 to 12.0 kN/m, and a tensile strength (horizontal) of 1.0 to 7.0 kN/m, Bekk smoothness (Bekk smoothness) 10 to 80 seconds. During its production, each deodorant can be easily impregnated into the paper layer. In addition, the deodorant can be retained and the odor components that volatilize in the toilet space can be in contact with the deodorant more appropriately.

In addition, the paper tube base paper 12 constituting the paper tube 11 is required to have sufficient strength so that it will not be damaged during the operation of winding the toilet paper S3 during manufacturing, and when the toilet paper roll 10 is made into the toilet paper roll 10 for use and transportation. From this point of view, it is desirable that the paper tube base paper has a tensile strength (longitudinal) of 4.0 to 12.0 kN/m and a tensile strength (horizontal) of 1.0 to 7.0 kN/m.

In addition, the density measurement method in the present invention and this specification is based on the method described in Japanese Industrial Standards JIS P 8118 (1998). In addition, Buick smoothness is based on Japanese Industrial Standards JIS P 8119 (1998), and tensile strength is based on the method described in Japanese Industrial Standards JIS P 8113 (2006).

On the other hand, the toilet paper roll 10 is often packaged with a film made of resin to form a product S, as shown in the packaging form shown in FIG. 6 . When the roll toilet paper 10 of the present invention is in this form, during the process of being transported to a store after manufacturing and being displayed as a product in a store, in order to prevent odor components from coming into contact with the deodorant, or the deodorant being inadvertently released. Since the deodorizing function is reduced due to long-term volatilization, it is desirable to package it with a film 20 made of a gas barrier resin with an oxygen permeability of 0.1 to 50 ml/m ² ·day (daily).

Examples of films made of this resin include polyethylene films, polypropylene films, polyethylene terephthalate films, polyvinylidene chloride films, and the like. The oxygen permeability measurement method in the present invention and this specification is based on Japanese Industrial Standards JIS K 7126 (2006) (isobaric method: MOCON method (water vapor transmission rate measurement method)/23°C × 65%RH) The one who got it by the method.

"How to make toilet paper rolls" Next, the manufacturing method of the roll toilet paper in this embodiment is demonstrated mainly with reference to FIG. 3 - FIG. 6. The manufacturing method of the roll toilet paper 10 of this embodiment has the process (A) of manufacturing the long-distance paper tube 11L; the raw material (log) manufacturing process (B); and the cutting process (C). However, the manufacturing method of the roll toilet paper of this invention is not necessarily limited to the method of this embodiment.

As shown in Figure 4, in the step (A) of manufacturing the long-distance paper tube 11L ((A) in Figure 3), two pieces of strip-shaped paper tube base paper 12, 12 are extracted from the original rollers 12A, 12A. , and the paste 30 is applied at a specific position by the paste roller 13, and then the portion stained with the paste is overlapped and wound on the shaft (shaft) 15 using the core winder 14. After the spiral shape, the shaft 15 is pulled out, and the paper tube cutter 16 is used to cut the length specified to match the production type, thereby forming a cylindrical long-distance paper tube 11L. The amount of paste applied is not particularly limited, but is approximately 0.1 to 5.0 g/m ² . In addition, as the paste 30, a conventional paste for paper tubes can be used as long as the effect of the present invention is not hindered, and examples thereof include acrylic adhesive, hot melt adhesive, starch paste, PVA (polyvinyl alcohol), and the like.

Furthermore, each paper tube base paper 12 and 12 can use different raw materials. For example, one of the paper tube base papers can be printed, or the basis weight of each can be changed. In the present invention, the paper tube base paper 12 does not necessarily need to be the same paper tube base paper.

Then, simultaneously with or after manufacturing the long-distance paper tube 11L, the raw material manufacturing step ((B) in FIG. 3) can be used to manufacture the raw material 10R. In addition, the raw material 10R is a common term in the industry, and is an intermediate product having the same diameter as the final product, that is, the toilet paper roll 10, and having a width that is a plurality of parts of the final product.

The raw material 10R is produced by continuously or stepwise drawing out and winding the toilet paper raw papers S1 and S1 having substantially the same width as the long-distance paper tube 11L from the jumbo rolls JR and JR. Form raw material 10R. The winding device X2 can be used for this winding. Furthermore, the illustration shows that the toilet paper base paper S1 and S1 are drawn out from two jumbo rolls JR and JR, and the toilet paper base paper S2 with a double-layer structure is made at the overlapping portion 51, and then the conventional contact embossing is used. After the application device 54 and the punch line forming device 70 perform the application of the contact embossing CE and the formation of the punch line (not shown), the winding device 75 is used to take up the double-layer structure.

Furthermore, in the form shown in the figure, thin toilet paper is pulled out from two giant paper rolls and formed into a double-layer toilet paper base paper S2 with a laminated structure. However, the present invention is not limited to this double layer, and may be a single layer. or three floors or more. Furthermore, when forming a plural-layer structure, the basis weight and physical properties of each base paper do not need to be the same.

Then, as long as the raw materials 10R are produced in this way, a plurality of the raw materials 10R are stored in the log accumulator (log accumulator) X3 and moved to the raw material cutting equipment X4. Then, as shown in (C) in FIG. 3 , the raw material 10R is cut into the product width using a conventional raw material cutting machine 76 to produce each roll toilet paper 10 .

As shown in FIG. 6 , a plurality of the obtained rolls of toilet paper 10 are packaged together with a film made of resin to form a roll of toilet paper products. In this case, if it is packaged with a film made of a gas barrier resin with an oxygen permeability of 0.1 to 50 ml/m ² ·day, it will be a better package, and it will be shipped to the store after production. During the process and the process of displaying it as a product in a store, the odor components will not come into contact with the deodorant, or the deodorant will evaporate unintentionally, resulting in a reduction in the deodorizing function.

In the manufacturing method of the toilet paper roll 10 in the present invention, the catechin-based deodorant, the tannin-based deodorant, and the silver-loaded zeolite are coated and applied to the toilet paper S3 and subsequent paper tubes constituting the paper tube 11 At least one of the base papers 12 . However, among the paper tube base paper 12 and the toilet paper S3, generally speaking, the paper tube base paper 12 has a heavier basis weight and higher strength, so it is easier to apply the liquid chemical. In addition, toilet paper S3 aims at water disintegration, so its wetting power is low. Therefore, it is preferable to apply the paper tube base paper 12 to the paper tube base paper 12 rather than to the toilet paper S3 because the production becomes easier. In addition, specific examples and appropriate examples of the catechin-based deodorant, tannin-based deodorant, and silver-supported zeolite in the present production method are the same as those described for the toilet paper roll 10 described above.

The catechin-based deodorant, tannin-based deodorant and silver-loaded zeolite can be coated on the toilet paper S3 and the paper tube base paper 12, for example, by using various conventional coating machines, flexo printing machines, and gravure printing machines. Printing machines, inkjet printers and other printing machines, spraying equipment to implement. The catechin-based deodorant, the tannin-based deodorant, and the silver-loaded zeolite can each be separately provided. However, it is desirable to apply the deodorant liquid agent 40 by applying the deodorant liquid agent to each of the deodorant liquid agents. A mixing step is performed before the agent to prepare a mixture of a catechin-based deodorant, a tannin-based deodorant, and a silver-loaded zeolite. Coating equipment and manufacturing steps can be reduced. In addition, the catechin-based deodorant and the tannin-based deodorant may use an extract mixture in which at least one of catechin catechins and catechin derivatives, tannins, and tannins are premixed. at least one of the derivatives. Examples of such an extract mixture include extract mixtures manufactured by Stanley Pharm (C) Co., Ltd.

In this case, it is particularly desirable to combine a deodorant liquid preparation containing a catechin-based deodorant, a tannin-based deodorant, and a silver-supported zeolite with a deodorant containing diethylene glycol monoethyl ether and isopropyl alcohol. Liquid chemicals are mixed to prepare a coating liquid. As shown in FIG. 5 , the permeability of the deodorant liquid agent 40 to the paper tube base paper 12 becomes good, and the deodorant liquid agent 40 can be easily impregnated into the paper layer of the paper tube base paper 12 without causing deodorization. The deodorant liquid agent 40 is unevenly applied. That is, the catechin-based deodorant and the tannin-based deodorant can be penetrated into the fiber and the silver-loaded zeolite can be transported into the fiber, and an unprecedented imparting form can be created, which makes the catechin The plain deodorant, the tannin deodorant, and the silver-loaded zeolite are adhered to the fibers of the paper tube base paper constituting the inner peripheral surface of the paper tube or are held in the gaps between the fibers. This form does not cover the deodorant as described above, so the deodorizing effect is extremely high. Furthermore, the liquid pharmaceutical containing diethylene glycol monoethyl ether and isopropyl alcohol is expected to further contain 2,4,7,9-tetramethyl-5-decyne-4,7-diol. It will be easier to apply. Furthermore, the deodorant liquid agent alone is difficult to penetrate the deodorant and the like into the paper tube base paper, and even if it is applied, it is easy to cause a so-called repellence state on the paper tube base paper. In addition, adhesives such as acrylic resins used for individual adhesion in the past are mixed with deodorant liquids containing catechin-based deodorants, tannin-based deodorants, and silver-loaded zeolites. , becomes prone to foaming and there is also the concern of covering up the deodorant after application.

An example of a position where the deodorant liquid chemical 40 is applied to the paper tube base paper 12 is the front stage of the paper core winding machine shown in FIG. 4 . However, it is not specifically limited. When forming the paper tube 11, it is preferable to place it at a position that will become one side of the paper tube base paper 12 constituting the inner peripheral surface of the paper tube.

The position at which the deodorant liquid agent containing each deodorant is applied to the toilet paper S3 can be determined by targeting the toilet paper base papers S1 and S1 in the front stage of the overlapping portion 51 in the winding device X2 shown in FIG. 3 It can also be performed on the toilet paper base paper S2 with a double-layer structure at the rear stage of the overlapping portion 51 . The specifics are not limited.

When coating on the paper tube base paper 12, it is expected that the thickness of the paper tube base paper 12 is 100-400 μm and the basis weight is 130-200 g/m ² . The coating amount of the paper tube base paper 12 is preferably 3.0 to 6.0 g/m ² . If the thickness of the paper tube base paper 12 is 100 to 400 μm and the basis weight is 130 to 200 g/m ² , the deodorant liquid agent 40 applied as shown in Figure 5 will easily penetrate, and as long as the coating amount is 3.0 ~6.0 g/m ² , it is easy to achieve sufficient deodorizing effect. In addition, if the density of the paper tube base paper 12 is set to 0.2 to 1.8 g/m ² and the Buick smoothness is set to 10 to 80 seconds, the permeability of the deodorant liquid agent will become more reliable, and the deodorant liquid agent will become more reliable. The agent 40 will become easier to apply. The proportions of the catechin-based deodorant, the tannin-based deodorant, and the silver-supported zeolite in the deodorant liquid preparation are not necessarily limited.

Through the above manufacturing method, it is possible to suitably manufacture a toilet paper roll that has an excellent deodorizing effect on methylmercaptan, trimethylamine, hydrogen sulfide, and ammonia, which are the main components of urine odor and feces odor. , and can also be made into an unscented form. Furthermore, for example, when a deodorant is added to toilet paper and a roll of toilet paper without a paper tube is produced, which is called a coreless type, the step (A) of manufacturing the long paper tube 11L is not required. [Example]

Next, using the examples, comparative examples, and standard products, it was confirmed that the main odor components in the toilet space, that is, ammonia gas, and Deodorizing effects of trimethylamine, hydrogen sulfide, and methylmercaptan.

The samples in the Examples, Comparative Examples, and Standard Products were a single paper tube with a width of 114 mm and an inner diameter of 41 mmφ. The paper tube is a spiral paper tube made by the method shown in Figure 4.

An example is a form in which a deodorant liquid agent mixed with a catechin-based deodorant and a tannin-based deodorant is applied to the surface that becomes the inner circumferential surface of the paper tube of the inner paper tube base paper. Deodorant and silver-loaded zeolite, and the catechin-based deodorant, tannin-based deodorant, and silver-loaded zeolite are adhered to the fibers of the paper tube base paper constituting the inner peripheral surface of the paper tube or are held between the fibers. in the gap. The comparative example is a form in which a deodorant liquid agent is applied to the inner circumferential surface of the paper tube that becomes the base paper of the inner paper tube instead of the deodorant liquid agent of the example, and the deodorant liquid agent is mixed There are catechin-based deodorants and tannin-based deodorants, and they do not contain silver-loaded zeolite. The standard product is one without deodorant.

The catechin-based deodorants and tannin-based deodorants in the examples and comparative examples are extract mixtures (#2571103) manufactured by Stanley Pharm (C) co., Ltd., which contain tea catechin and persimmon catechins and set these as the main active ingredients. In the examples, Zaobaset AG-30N manufactured by Daiwa Chemical Industry Co., Ltd. containing silver-supported zeolite was used. In addition, the deodorant liquid agent in the examples and comparative examples was mixed with a liquid agent containing diethylene glycol monoethyl ether and isopropyl alcohol (New FK MR OP paint G-790, manufactured by SAKATA INX CORPORATION) Carry out coating. Furthermore, in the example, a catechin-based deodorant and tannin were added to a liquid agent obtained by mixing Zaobaset AG-30N: New FK MR OP paint G-790: water in a volume ratio of 3:3:4. It is modified by deodorant. Examples and comparative examples were adjusted so that the added amounts of the catechin-based deodorant and the tannin-based deodorant would be the same amount.

(Adjustment of ammonia gas) A PVDF-made odor bag (5L) sealed with ammonia-containing filter paper (Adventec. Co., Ltd. 100 CIRCLES) was filled with air, and the air in the odor bag was appropriately sucked using a syringe, and then injected into the separately prepared paper containing each sample. The tube was placed in a PVDF odor bag (5L), and the initial concentration of ammonia in the PVDF odor bag was directly adjusted so that it became 100 ppm.

(Adjustment of trimethylamine) A PVDF-made odor bag (5L) sealed with filter paper (Adventec. Co., Ltd. 100 CIRCLES) containing a trimethylamine aqueous solution was filled with air. Use a syringe to appropriately absorb the air in the odor bag and inject it into a separately prepared container. Examples into a paper tube made of PVDF scent bag (5L), and directly adjusted so that the initial concentration of trimethylamine in the PVDF scent bag became 28 ppm.

(Adjustment of hydrogen sulfide) A PVDF-made odor bag (5L) sealed with filter paper (Adventec. Co., Ltd. 100 CIRCLES) containing a hydrogen sulfide aqueous solution was filled with air, and a syringe was used to appropriately absorb the air in the odor bag and inject it into a separately prepared container. Examples into a paper tube made of PVDF scent bag (5L), and directly adjusted so that the initial concentration of hydrogen sulfide in the PVDF scent bag became 4 ppm.

(Adjustment of methyl mercaptan) A PVDF-made odor bag (5L) sealed with filter paper (Adventec. Co., Ltd. 100 CIRCLES) containing a methyl mercaptan aqueous solution was filled with air. Use a syringe to appropriately absorb the air in the odor bag and inject it into a separately prepared container. In the paper tube of the example, a PVDF scent bag (5L) was directly adjusted so that the initial concentration of methyl mercaptan in the PVDF scent bag became 8 ppm.

For the concentration measurement of ammonia, trimethylamine, hydrogen sulfide, and methyl mercaptan, after adjusting to the initial concentration, measure the concentrations after 0 minutes, 30 minutes, and 60 minutes, and calculate the ammonia concentration from the measured values. reduction rate to be implemented. Permeater PD-1B and gas detection tube 3La manufactured by GASTEC CORPORATION were used for the measurement. The reduction rate was calculated as ((measured value after 0 minutes - measured value after 30 minutes or 60 minutes)/(measured value after 0 minutes)) × 100. The results are shown in Table 1.

Regarding ammonia and trimethylamine, in the Examples, Comparative Examples and Standard Products, the reduction rates were high after 30 minutes and 60 minutes. However, the reduction rate after 30 minutes was the highest in the Examples, which shows that The present invention can exhibit a rapid deodorizing effect of malodors derived from ammonia gas and trimethylamine. In addition, the standard product not coated with deodorant also had a high reduction rate, and it was confirmed that the paper tube base paper itself absorbs odor to a certain extent. That is, for the deodorization of ammonia gas, it is expected that the position where the deodorant is applied is the inner surface of the paper tube.

Regarding hydrogen sulfide, the comparative example and the standard product had almost no deodorizing effect even after 60 minutes, and only the example showed a high reduction rate after 30 minutes and 60 minutes. In particular, the reduction rate reached 82.5% after 30 minutes, and it was confirmed that hydrogen sulfide can be quickly deodorized by containing silver-supported zeolite.

Regarding methyl mercaptan, both the Examples and the Comparative Examples showed a deodorizing effect compared to the standard product. However, the Example showed a high deodorizing effect due to a reduction rate of about 6 times compared to the Comparative Example.

In the examples, the catechin-based deodorant and the tannin-based deodorant showed excellent deodorizing effects on ammonia and trimethylamine, and the silver-loaded zeolite showed rapid deodorizing effects on hydrogen sulfide and methyl mercaptan. It has an odor-free effect and does not hinder the excellent deodorizing effect of catechin-based deodorants and tannin-based deodorants on ammonia and trimethylamine. Therefore, the present invention can provide toilet paper rolls, etc., which have an excellent deodorizing effect on methylmercaptan, trimethylamine, hydrogen sulfide, and ammonia, which are the main components of urine odor and feces odor, and can also be made into non-toxic toilet paper. Fragrance form.
