Abstract
Description
本発明は、柔らかさと消臭抗菌作用のある保湿紙およびその製造方法に関する。 The present invention relates to a moisture retaining paper having softness and deodorizing antibacterial action and a method for producing the same.
近年、花粉症等のアレルギー対策として、ローションティッシュに代表される柔らかさのある紙製品が上市されている。また、生活のあらゆる場に抗菌ブームが及んでおり、製紙業界でも銀イオンをはじめとした無機系抗菌剤が使用されている。そこで、消臭及び抗菌の両機能を併せ持った茶葉もしくは茶ポリフェノールを使用した紙製品が考えられたが、柔らかさと消臭及び抗菌の両機能を併せ持った紙製品などは存在しなかった。 In recent years, soft paper products represented by lotion tissue have been put on the market as countermeasures against allergies such as hay fever. In addition, the antibacterial boom is spreading everywhere in life, and inorganic antibacterial agents such as silver ions are used in the paper industry. Thus, paper products using tea leaves or tea polyphenols having both deodorant and antibacterial functions were considered, but there were no paper products having both softness, deodorant and antibacterial functions.
例えば、特許文献１には、含水性のティッシュ用基紙に、茶葉から抽出した茶葉抽出物を含浸したウェットティッシュの記載がある。しかし、保湿剤を使用しないため柔らかさと茶ポリフェノールの抗菌性が乏しいウェットティッシュになるという問題点があった。 For example, Patent Document 1 describes a wet tissue in which a water-containing tissue base paper is impregnated with a tea leaf extract extracted from tea leaves. However, since a moisturizer is not used, there is a problem that the wet tissue has poor softness and antibacterial properties of tea polyphenol.
また、特許文献２には、緑茶製造工程の揉機による揉み工程において発生する皮状物質を使用した脱臭紙が記載されている。しかし、揉機工程にて発生する皮状物質は粒径１ｍｍ以上の茶葉や茶葉同士が接合された塊であり、粒径や性状、水分率にバラツキがあった。そのため、紙に配合しやすくするために皮状物質の乾燥・粉砕もしくはペースト化処理が必要となり、コスト的にも問題があった。また、粒径の細かい茶葉由来の皮状物質が乾燥工程にて熱劣化を起こす可能性があるという問題点もあった。 Further, Patent Document 2 describes deodorized paper using a skin-like substance generated in a brewing process by a brewing machine in a green tea manufacturing process. However, the skin-like substance generated in the kneading process is a tea leaf having a particle size of 1 mm or more or a lump of tea leaves joined together, and there are variations in the particle size, properties, and moisture content. Therefore, in order to make it easy to mix with paper, it is necessary to dry, pulverize or paste the skin-like substance, which causes a problem in terms of cost. In addition, there is also a problem that a skin-like substance derived from tea leaves having a fine particle size may cause thermal deterioration in the drying process.
また、特許文献３には、従来ある乾式家庭紙、湿式家庭紙に腐敗臭・悪臭だけを完全消臭する無害、無臭の有機化合物の消臭液を含漬させた乾式家庭紙、湿式家庭紙が記載されている。しかし、無害、無臭の有機化合物は茶ポリフェノールを含むものではなく、柔らかさと消臭及び抗菌の両機能を併せ持つものでもなかった。 Patent Document 3 discloses conventional dry household paper, wet household paper, dry household paper, wet household paper in which a deodorizing solution of a harmless and odorless organic compound that completely deodorizes only rotten odor and malodor is impregnated. Is described. However, harmless and odorless organic compounds do not contain tea polyphenols, nor do they have both softness, deodorization and antibacterial functions.
同様に、特許文献４には、吸湿性を有する塩類、多価アルコール及び糖類のうちの少なくとも一種、または、これらのうちの一種及び保水性を有する糊料を繊維ウェブに含有させた高水分含有繊維ウェブが記載されている。しかし、茶ポリフェノールを含むものではなく、柔らかさと消臭及び抗菌の両機能を併せ持つものでもなかった。 Similarly, Patent Document 4 discloses a high moisture content in which a fibrous web contains at least one of a hygroscopic salt, a polyhydric alcohol, and a saccharide, or one of these and a water-holding paste. A fiber web is described. However, it did not contain tea polyphenols, nor did it have both softness, deodorant and antibacterial functions.
また、特許文献５には、天然パルプ主体の紙の表面に茶抽出物を塗工した食品用抗菌紙が記載されている。しかし、茶抽出物の塗工後に乾燥工程があり、乾燥温度によっては茶抽出物が変色して柔らかさに欠ける食品用抗菌紙になるという問題点があった。 Patent Document 5 describes a food antibacterial paper in which a tea extract is applied to the surface of a natural pulp-based paper. However, there is a drying process after the application of the tea extract, and depending on the drying temperature, there is a problem that the tea extract is discolored to become a food antibacterial paper lacking in softness.
同様に、特許文献６にも乾燥工程があり、茶抽出物が変色して柔らかさに欠ける紙製品になるという問題点があった。 Similarly, Patent Document 6 also has a drying process, which has a problem that the tea extract is discolored to become a paper product lacking in softness.
また、特許文献７には、常法により得られた水解紙のウェブ形成時又は後に、水溶性高分子と二個以上の水酸基が置換されたベンゼン核を含有する化合物（緑茶抽出物）を塗布して乾燥させ、その後、水解紙を湿潤させる溶液(水)に含浸させるなどした水解性ウェットティッシュが記載されている。しかし、十分な湿潤引張強度を持った水解紙ではあるが、湿潤させる溶液が水であるため、柔らかさと消臭及び抗菌の両機能を併せ持つものではなかった。 Patent Document 7 is coated with a compound (green tea extract) containing a water-soluble polymer and a benzene nucleus substituted with two or more hydroxyl groups during or after the formation of a web of hydrolytic paper obtained by a conventional method. A water-degradable wet tissue is described that is dried and then impregnated with a solution (water) that wets hydrolyzed paper. However, although it is a hydrolytic paper having a sufficient wet tensile strength, it does not have both functions of softness, deodorization and antibacterial because the solution to be wetted is water.
また、特許文献８には、茶葉を抄紙機のワイヤーパート手前の段階で混入し、棒茶、粉茶等の外観形態と混合比率に応じて紙繊維中に散在した茶葉が、やゝ立体状に形成された脱臭・芳香機能を有する紙シートが記載されている。しかし、ワイヤーパート手前の段階で混入した茶葉をプレス工程にて脱水しても紙繊維と茶葉の保持する水分率の違いにより次工程の乾燥が難しくなり、また、茶葉繊維と紙繊維の弾力性の違いにより茶葉の剥離が起こる可能性があるという問題点があった。 In Patent Document 8, tea leaves are mixed in the stage before the wire part of the paper machine, and tea leaves scattered in the paper fiber according to the appearance form and mixing ratio of stick tea, powdered tea, etc. A paper sheet having a deodorizing and aroma function formed in is described. However, even if the tea leaves mixed in the stage before the wire part are dehydrated in the press process, it becomes difficult to dry the next process due to the difference in moisture content retained by the paper fibers and tea leaves, and the elasticity of the tea leaf fibers and paper fibers. There was a problem that the tea leaves may be peeled off due to the difference.
同様に、特許文献９には、破片状に調製した茶殻と繊維状パルプとを絡み合わせて抄紙した茶殻配合紙が記載されている。しかし、乾燥工程が難しく、また、茶殻繊維と繊維状パルプとの弾力性の違いにより茶殻の剥離が起こる可能性があるという問題点があった。 Similarly, Patent Document 9 describes a tea husk blended paper that is made by intertwining a tea husk prepared in a fragmented form with fibrous pulp. However, there is a problem that the drying process is difficult, and there is a possibility that peeling of the tea husk may occur due to the difference in elasticity between the tea husk fiber and the fibrous pulp.
本発明の目的は、柔らかさと消臭抗菌作用のある保湿紙を提供することにある。より具体的には、衛生用基紙に、茶ポリフェノール及び保湿剤を塗布又は含浸させることで、柔らかさや肌触りが向上し、かつ、消臭抗菌作用を有する保湿紙およびその製造方法を提供することにある。 An object of the present invention is to provide a moisturizing paper having softness and deodorant antibacterial action. More specifically, by providing or impregnating sanitary base paper with tea polyphenol and a moisturizing agent, softness and touch are improved, and a moisturizing paper having a deodorizing and antibacterial action and a method for producing the same are provided. It is in.
本発明者らは、上記課題解決のために鋭意研究を行った結果、衛生用基紙に、茶ポリフェノール及び保湿剤を塗布又は含浸させることにより、柔らかさや肌触りが向上し、かつ、消臭抗菌作用を有する保湿紙を見出した。また、前記衛生用基紙に、前記茶ポリフェノールを０．２〜１．８重量％含有させることで消臭抗菌作用を有し、さらに、前記保湿剤を５〜３０重量％含有させることで柔らかさがあり、他の紙などにローション溶液や保湿剤が移行しない保湿紙を見出した。 As a result of diligent research to solve the above problems, the present inventors have improved the softness and feel of the sanitary base paper by applying or impregnating tea polyphenol and moisturizing agent, and deodorizing antibacterial properties. A moisturizing paper having an action was found. The sanitary base paper has a deodorizing and antibacterial action by containing 0.2 to 1.8% by weight of the tea polyphenol, and further softening by containing 5 to 30% by weight of the moisturizing agent. We found a moisturizing paper that does not transfer lotion solution or moisturizing agent to other paper.
また、茶ポリフェノールを溶媒に添加して茶ポリフェノール溶液を作製する工程と、前記茶ポリフェノール溶液を保湿剤に添加してローション溶液を作製する工程と、前記ローション溶液を衛生用基紙に塗布又は含浸することで、保湿剤を単独で塗布するよりも柔らかさや肌触りが向上し、かつ、消臭抗菌作用を有する保湿紙の製造方法を見出した。すなわち、本発明は、以下に記載の手段を採用する。 Also, a step of adding tea polyphenol to a solvent to prepare a tea polyphenol solution, a step of adding the tea polyphenol solution to a moisturizer to prepare a lotion solution, and applying or impregnating the lotion solution to a sanitary base paper Thus, the present inventors have found a method for producing a moisturizing paper that has improved softness and touch as compared with the case where a moisturizing agent is applied alone and has a deodorizing and antibacterial action. That is, the present invention employs the following means.

本発明は、衛生用基紙に、茶ポリフェノール及び保湿剤を塗布又は含浸させることにより、柔らかさや肌触りが向上し、かつ、消臭抗菌作用を有する保湿紙を得ることができる。
その際、前記衛生用基紙が、前記茶ポリフェノールを０．２〜１．８重量％含有するようにし、好ましくは０．３〜１．８重量％、さらに好ましくは０．３〜１．５重量％含有するようにする。茶ポリフェノールが０．１重量％以上で消臭抗菌作用が表れ、０．２重量％以上で大腸菌への抗菌作用及び、アンモニアガスの消臭作用が表れる。茶ポリフェノールの含有量は、最終製品である保湿紙に起こる茶ポリフェノールの析出が生じないような量とし、消臭抗菌作用とコストの兼ね合いにより適宜調整する。上限は１．８重量％が目安と考えられる。
In the present invention, by applying or impregnating tea polyphenol and a moisturizing agent to a sanitary base paper, it is possible to obtain a moisturizing paper having improved softness and touch and having a deodorizing and antibacterial action.
At that time, the sanitary base paper contains 0.2 to 1.8% by weight of the tea polyphenol, preferably 0.3 to 1.8% by weight, more preferably 0.3 to 1.5%. It is made to contain by weight. When the tea polyphenol is 0.1% by weight or more, the deodorizing and antibacterial action appears, and when it is 0.2% by weight or more, the antibacterial action against Escherichia coli and the deodorizing action of ammonia gas appear. The content of the tea polyphenol is adjusted so as not to cause the precipitation of the tea polyphenol that occurs in the moisturizing paper as the final product, and is appropriately adjusted depending on the balance between the deodorizing antibacterial action and the cost. The upper limit is considered to be 1.8% by weight.
また、前記衛生用基紙が、前記保湿剤を５〜３０重量％含有するようにし、好ましくは１０〜２５重量％、さらに好ましくは１０〜２０重量％含有するようにする。保湿剤が５重量％以上で保湿紙に柔らかさが出てくる。保湿座剤を多く含有させすぎると他の紙などに保湿剤が移行してしまうので適宜調整する。上限は３０重量％が目安と考えられる。 The sanitary base paper contains 5 to 30% by weight of the humectant, preferably 10 to 25% by weight, and more preferably 10 to 20% by weight. When the moisturizing agent is 5% by weight or more, softness appears on the moisturizing paper. If too much moisturizing suppository is contained, the moisturizing agent will be transferred to other papers and the like, so adjust accordingly. The upper limit is considered to be 30% by weight.
また、本発明は、茶ポリフェノールを溶媒に添加して茶ポリフェノール溶液を作製する工程と、前記茶ポリフェノール溶液を保湿剤に添加してローション溶液を作製する工程と、前記ローション溶液を衛生用基紙に塗布又は含浸して柔らかさを１．７１ｍＮ／１００ｍｍ以下に調整する工程とを含むことで保湿紙を製造することができる。 The present invention also includes a step of preparing a tea polyphenol solution by adding tea polyphenol to a solvent, a step of preparing a lotion solution by adding the tea polyphenol solution to a moisturizing agent, and the lotion solution as a sanitary base paper. A moisturizing paper can be produced by including a step of applying or impregnating to a softness of 1.71 mN / 100 mm or less.
その際、粉末状の茶ポリフェノールを保湿剤に直接添加して溶解しようとすると茶ポリフェノールが不溶解物として残りやすいことを見出したため、予め少量の水などの溶媒で茶ポリフェノールを溶解し、茶ポリフェノール溶液としてから保湿剤に添加してローション溶液を作製する。なお、ローション溶液中の水分量は、１１〜１８重量％、好ましくは１１〜１５重量％に調製する。ローション溶液の水分量が１１％以上にすると茶ポリフェノールがダマになりにくい。水分が多すぎるとすぐに保湿剤と茶ポリフェノール溶液が分離してしまうので適宜調整する。上限は１８％が目安と考えられる。保湿剤に予め定量の水を添加した後、茶ポリフェノールを添加して溶解することも可能であるし、茶抽出液をそのまま添加してローション溶液を調製しても良い。 At that time, it was found that the tea polyphenol was likely to remain as an insoluble matter when the powdered tea polyphenol was directly added to the moisturizing agent, so that the tea polyphenol was dissolved in a small amount of a solvent such as water in advance. The solution is then added to the humectant to make a lotion solution. The water content in the lotion solution is adjusted to 11 to 18% by weight, preferably 11 to 15% by weight. If the water content of the lotion solution is 11% or more, the tea polyphenols are less likely to become lumps. As soon as there is too much moisture, the moisturizer and the tea polyphenol solution will be separated, so adjust accordingly. The upper limit is considered to be 18%. It is possible to add a predetermined amount of water to the moisturizer in advance, and then add tea polyphenol to dissolve, or a lotion solution may be prepared by adding the tea extract as it is.
本発明において塗布又は含浸するとは、衛生用基紙に常法にて均一に塗布又は含浸することをいう。例えば、衛生用基紙にロールコーター（ローション塗布機；川之江造機(株)製））を用いて衛生用基紙表面に均一に塗布することもできるし、衛生用基紙をローション溶液等に均一に浸るようにして含浸することもできる。その後、塗布又は含浸された衛生用基紙を常温にて１時間以上、好ましくは１２時間以上、さらに好ましくは２４時間以上静置して保湿紙を得る。 In the present invention, “applying or impregnating” means uniformly applying or impregnating a sanitary base paper by a conventional method. For example, a roll coater (lotion applicator; manufactured by Kawanoe Kikai Co., Ltd.) can be applied uniformly to the sanitary base paper, or the sanitary base paper can be uniformly applied to the lotion solution. It is also possible to impregnate by soaking. Thereafter, the coated or impregnated sanitary base paper is allowed to stand at room temperature for 1 hour or longer, preferably 12 hours or longer, more preferably 24 hours or longer to obtain a moisture retaining paper.
また、本発明における柔らかさとは、試験片（保湿紙）を一定の隙間に押し込むときに受ける抵抗力を指し、曲げと滑りの複合値を表す。本発明では、ＪＡＰＡＮ

以下、本発明を実施例により具体的に説明するが、本発明はこれらにより限定されるものではない。 EXAMPLES Hereinafter, the present invention will be specifically described with reference to examples, but the present invention is not limited thereto.
茶ポリフェノールとしては、表１に示すような成分を有する緑茶抽出ポリフェノール（商品名：テアフラン３０Ａ（粉末）；伊藤園社製）を準備した。また、保湿剤としては、グリセリン（商品名：ＲＧ；日本油脂社製）、ポリエチレングリコール（商品名：ＰＥＧ２００；日本油脂社製）及び水（純水）を７５：１５：１０の割合で混合した溶液（以下、保湿剤Ａ）を準備した。 As the tea polyphenol, a green tea extracted polyphenol (trade name: Teafuran 30A (powder); manufactured by ITO EN) having components as shown in Table 1 was prepared. Moreover, as a moisturizer, glycerin (trade name: RG; manufactured by NOF Corporation), polyethylene glycol (trade name: PEG200; manufactured by NOF Corporation) and water (pure water) were mixed in a ratio of 75:15:10. A solution (hereinafter, humectant A) was prepared.
（ローション溶液の調製）
前記保湿剤Ａに、前記緑茶抽出ポリフェノール（総ポリフェノール；粉末）が１．５重量％含有するように添加した後、１０分間攪拌してローション溶液を調製した（比較例）。
また、前記緑茶抽出ポリフェノールを予め純水にて溶解して茶ポリフェノール溶液を調製し、表２に示すような配合となるようにローション溶液を調製した。その後、ローション溶液の分離状態の有無を観察した。
(Preparation of lotion solution)
To the moisturizer A, the green tea extracted polyphenol (total polyphenol; powder) was added so as to contain 1.5% by weight, and then stirred for 10 minutes to prepare a lotion solution (Comparative Example).
Moreover, the said green tea extraction polyphenol was previously melt | dissolved in the pure water, the tea polyphenol solution was prepared, and the lotion solution was prepared so that it might become a mixing | blending as shown in Table 2. Thereafter, the presence or absence of a separated state of the lotion solution was observed.
保湿剤Ａに、緑茶抽出ポリフェノール（粉末）を直接添加したローション溶液（比較例）の場合、緑茶抽出ポリフェノールは溶解せずダマになってしまうが、予め純水にて溶解した緑茶抽出ポリフェノールを添加することでその問題は解消され、さらに、保湿剤Ａと茶ポリフェノール溶液は分離しない。しかし、ローション溶液中の水分量が１８％だと２４時間後には分離してしまい、水分量が２０％だと５分後には分離してしまった。 In the case of a lotion solution (comparative example) in which green tea extracted polyphenol (powder) is directly added to moisturizer A, the green tea extracted polyphenol does not dissolve, but it becomes lumpy, but the green tea extracted polyphenol previously dissolved in pure water is added By doing so, the problem is solved, and the humectant A and the tea polyphenol solution are not separated. However, when the water content in the lotion solution was 18%, separation occurred after 24 hours, and when the water content was 20%, separation occurred after 5 minutes.
（カビ発生試験）
前記保湿剤Ａに表１記載の緑茶抽出ポリフェノールを添加して表３に示すような配合となるようにローション溶液を衛生用基紙（坪量２７.５ｇ/ｍ２）にロールコーターを用いて均一に塗布した後、常温にて１時間静置した。その後、ポリエチレン製の密封容器に入れ、３７℃にて１０日間保存試験に供した後、保湿紙の状態を確認した。

After uniformly coating, it was allowed to stand at room temperature for 1 hour. Then, after putting in the sealed container made from polyethylene and using for the storage test for 10 days at 37 degreeC, the state of the moisturizing paper was confirmed.
ローション溶液の塗布量が４０重量％になると保湿紙にカビの発生が若干見られ、４５重量％ともなると保湿紙全体にカビの発生が見られた。このことから、ローション溶液の塗布量が多くなると、保湿紙中に含まれる茶ポリフェノール量は多くなるが、その分、保湿紙に占める保湿剤由来の水分量が多くなり、カビが発生したものと思われた。 When the application amount of the lotion solution was 40% by weight, some generation of mold was observed on the moisturizing paper, and when it was 45% by weight, generation of mold was observed on the entire moisturizing paper. From this, when the application amount of lotion solution increases, the amount of tea polyphenol contained in the moisturizing paper increases, but the amount of moisture derived from the moisturizing agent in the moisturizing paper increases, and mold is generated. It seemed.
（ローション溶液の移行試験）
前記保湿剤Ａに表１記載の緑茶抽出ポリフェノールを添加して表４に示すような配合となるようにローション溶液を衛生用基紙（坪量２７.５ｇ/ｍ２）にロールコーターを用いて均一に塗布した後、常温にて１時間静置した。その後、市販のＡ４普通紙２枚を挟んで両側から５ｋｇ/ｃｍ２の圧力をかけ、保湿紙に含まれるローション溶液がＡ４普通紙に移行しないかどうかを確認した。
(Lotion solution transfer test)
Using a roll coater on a sanitary base paper (basis weight 27.5 g / m 2 ) so that the moisturizer A is added with the green tea extraction polyphenols shown in Table 1 and blended as shown in Table 4. After uniformly coating, it was allowed to stand at room temperature for 1 hour. Thereafter, a pressure of 5 kg / cm 2 was applied from both sides across two commercially available A4 plain papers, and it was confirmed whether the lotion solution contained in the moisturizing paper would not transfer to A4 plain papers.
ローション溶液の塗布量が３５重量％になると本発明で得た保湿紙を中心にして挟み込んだ市販のＡ４普通紙（上、下２枚）にローション溶液が移行した。
このことから、ローション溶液の塗布量が多くなると、保湿紙に含まれるローション溶液が移行することが分かった。
When the application amount of the lotion solution was 35% by weight, the lotion solution was transferred to a commercially available A4 plain paper (upper and lower two sheets) sandwiched around the moisturizing paper obtained in the present invention.
From this, it was found that the lotion solution contained in the moisture retaining paper migrates as the application amount of the lotion solution increases.
