Description
本発明は、消臭効果およびその持続性に優れ、かつ水洗による再使用が可能な高機能性消臭和紙およびこれを製造するための方法に関するものである。 The present invention relates to a highly functional deodorized Japanese paper that is excellent in deodorizing effect and its sustainability and can be reused by washing with water, and a method for producing the same.
従来、家庭用の消臭商品として、化学合成消臭剤が多く使用されているが、これらの消臭商品にあっては、速効性を有しているものの、その消臭効果が比較的に小さく、かつ消臭効果の持続性もかなり低いうえに、消臭効果を復元させて再使用（リサイクル）することができないという欠点を有している。 Conventionally, many synthetic synthetic deodorants have been used as household deodorant products, but these deodorant products have a fast-acting effect, but their deodorizing effect is relatively low. It has a drawback that it is small and has a fairly low deodorizing effect and cannot be reused (recycled) by restoring the deodorizing effect.
これに対して、冷蔵庫の中で使用されている活性炭を使用した消臭商品などは、天然素材を用いたものであって、比較的消臭効果の持続性が高いものの、大型でかさばり、かつ高価であるとともに、容易には再使用することができないという欠点を有している。 On the other hand, deodorized products using activated carbon used in refrigerators are made of natural materials and have a relatively high deodorizing effect, but they are large and bulky. It has the disadvantages of being expensive and not easily reusable.
一方、天然繊維である和紙は、軽量で水洗に耐えうるために、当該和紙に速効性がある消臭剤を定着させることにより、消臭効果に優れるとともに、安価で取り扱いが容易な消臭商品と成り得るが、特に上記和紙は、消臭剤を強固に定着することが困難であるために、消臭効果の持続性や、水洗等による再使用を実現することが難しいという問題点があった。現在、消臭紙として、茶葉に含まれるカテキン等を紙に混入したポケットティッシュが販売されているが、その用途は靴やカバン等小物の消臭に限られている。また、下記特許文献１には金属イオン（銅イオン、第二鉄イオン）をレーヨンファイバーに導入させた消臭繊維を紙に混入した消臭紙が開示されており、消臭機能は高いが高価であるため汎用的ではない。
On the other hand, natural paper Japanese paper is light and can withstand water washing, and by fixing a fast deodorant to the Japanese paper, it has excellent deodorizing effect and is inexpensive and easy to handle. However, in particular, the above Japanese paper has the problems that it is difficult to firmly fix the deodorant, and thus it is difficult to realize the deodorizing effect and reuse by washing. It was. Currently, as a deodorizing paper, a pocket tissue in which catechins and the like contained in tea leaves are mixed is sold, but its use is limited to deodorizing small items such as shoes and bags.
そこで、本発明者等は、上記和紙に対する消臭剤の定着に、下記特許文献２において開示したハイドロゲルが有効ではないかとの着想の元に、上記消臭剤として、消臭・殺菌効果に優れるヨウ素アニオン交換樹脂を消臭剤として用い、さらに当該消臭効果の持続・安定性を向上させる助剤としてトルマリンを配合するとともに、定着剤として上記ハイドロゲルを使用して、下記特許文献２において提案したハイドロゲル塗工和紙の技術により消臭和紙を試作して、消臭効果および持続性等に関する種々の実証試験を行った。
Therefore, the present inventors, as the deodorant, have a deodorizing / sterilizing effect based on the idea that the hydrogel disclosed in
そして、この結果、上記ハイドロゲルが有する強固な定着性によって、人体にも影響が無く、かつ消臭効果およびその持続性に優れるとともに、手軽な水洗により消臭効果を再生できるリサイクル機能を備えることにより、長期間の使用が可能となることから、経済性に優れた低コストの消臭和紙が得られるとの知見を得るに至った。 And as a result, the strong fixability of the hydrogel does not affect the human body, has a deodorizing effect and its sustainability, and has a recycling function that can regenerate the deodorizing effect by simple water washing. As a result, it has become possible to obtain a low-cost deodorized Japanese paper excellent in economic efficiency because it can be used for a long period of time.
本発明は、上記知見に基づいてなされたものであり、ハイドロゲルが有する高い定着効果によって、消臭効果およびその持続性に優れ、かつ水洗による再使用が可能な高機能性消臭和紙および当該消臭和紙の製造方法を提供することを課題とするものである。 The present invention has been made on the basis of the above findings, and has a high functional deodorizing Japanese paper that is excellent in the deodorizing effect and its sustainability due to the high fixing effect of the hydrogel and can be reused by washing with water. An object of the present invention is to provide a method for producing deodorized Japanese paper.

According to the invention of any one of
In addition, a strong deodorant fixing function with hydrogel on Japanese paper can exert a deodorizing effect over a long period of time, and when the deodorizing effect decreases, it can be easily washed at home. By simply performing the treatment, it is possible to wash away the decomposition substances of malodorous components and the like, so that the deodorizing effect can be restored and reused by drying again.
この結果、軽量でかさばらずに、しかも消臭効果と持続性に優れ、かつ水洗による再使用（リサイクル）が可能な安価な高機能性消臭和紙を提供することができる。 As a result, it is possible to provide an inexpensive high-functional deodorized Japanese paper that is lightweight and not bulky, has an excellent deodorizing effect and sustainability, and can be reused (recycled) by washing with water.
また特に、請求項２または４に記載の発明のように、和紙原料に上記ハイドロゲル混合液を加えて撹拌・混練し、これを抄紙して乾燥することによって得られた高機能性消臭和紙の両面に、当該和紙よりも薄い保護和紙を抄き合させ、その上からハイドロゲルを含浸させ、乾燥させることによって、より一段と消臭剤等の保持効果を高めることができる。この結果、水洗による再生を繰り返し行っても、消臭効果を持続させたままで、２年間程度の長期間にわたって使用することが可能になる。
In particular, as in the invention described in
次に、図１に示すフローチャートに基づいて、本発明に係る高機能性消臭和紙の製造方法の一実施形態について説明する。
なお、本実施形態において使用するハイドロゲルは、上記特許文献２において開示されている高吸収性デンプンゲルであって、カルボキシメチルセルロース（ＣＭＣ）とデンプンとをブレンドし、水と十分に練って糊状のペーストとした状態で、電離性放射線（γ線、電子線、Ｘ線）を照射することによって得られるものである。
Next, based on the flowchart shown in FIG. 1, one Embodiment of the manufacturing method of the highly functional deodorizing Japanese paper which concerns on this invention is described.
In addition, the hydrogel used in this embodiment is a superabsorbent starch gel disclosed in the above-mentioned
一般に、和紙は、その原料に硫酸バンド０．０〜２．０wt%、デンプンのり０．０〜２．０wt%およびサイズ剤０．０〜２．０wt%や染料（適宜）を配合して、抄紙をしている。
これに対して、上記高機能性消臭和紙を製造するには、先ず消臭剤としてのヨウ素アニオン交換樹脂３．０〜４０．０wt%および当該消臭剤の効果を持続安定させるためのトルマリン２．０〜１０．０wt%を、上記ハイドロゲルを１．０〜２．０wt%含む溶液に混入して分散させる。
In general, Japanese paper is blended with 0.0 to 2.0 wt% sulfate band, 0.0 to 2.0 wt% starch paste and 0.0 to 2.0 wt% sizing agent and dye (as appropriate) in its raw materials, I am making paper.
In contrast, in order to produce the above highly functional deodorized Japanese paper, first, iodine anion exchange resin 3.0 to 40.0 wt% as a deodorant and tourmaline for continuously stabilizing the effect of the deodorant. 2.0 to 10.0 wt% is mixed and dispersed in a solution containing 1.0 to 2.0 wt% of the hydrogel.
次いで、パルプ、コウゾ、ミツマタ等からなる和紙原料に、上記ヨウ素アニオン交換樹脂とトルマリンを配合したハイドロゲル溶液を、重量比で１．０wt%程度混入して攪拌する。
そして、従来の和紙の抄紙と同様に、上述した硫酸バンド、デンプンのりをそれぞれ添加するとともに、サイズ剤を配合する。
Next, about 1.0 wt% of the hydrogel solution in which the iodine anion exchange resin and tourmaline are blended in a Japanese paper raw material made of pulp, mulberry, Mitsumata or the like is mixed and stirred.
Then, as in the case of conventional Japanese papermaking, the above-described sulfuric acid band and starch paste are added, and a sizing agent is blended.
次いで、これを抄紙し、乾燥する。さらにハイドロゲル１．０wt%溶液を含侵させて、再び乾燥することにより、高機能性消臭和紙とする。 Next, the paper is made and dried. Further, a highly functional deodorized Japanese paper is obtained by impregnating a 1.0 wt% hydrogel solution and drying again.
ちなみに、本発明者等は、上記ハイドロゲルによる消臭剤等の定着効果を確認するために、図１に示すように、ヨウ素アニオン交換樹脂８．０wt%とトルマリン４．０wt%を、ハイドロゲル１．０wt%溶液に混入して分散させ、これを上記和紙原料に重量比１．０wt%混入して攪拌したものに、硫酸バンド３．０wt%、デンプンのり３．０wt%を添加するとともに、サイズ剤を配合して混練した後に、抄紙して乾燥し、さらにハイドロゲル１．０wt%溶液を含侵させて、再び乾燥することにより本発明に係る高機能性消臭和紙を作成した。 Incidentally, in order to confirm the fixing effect of the deodorant and the like by the hydrogel, the present inventors have used 8.0 wt% iodine anion exchange resin and 4.0 wt% tourmaline as shown in FIG. A 1.0 wt% solution was mixed and dispersed, and this was mixed with 1.0 wt% by weight of the Japanese paper raw material and stirred, to which 3.0 wt% sulfuric acid band and 3.0 wt% starch paste were added, After blending and kneading the sizing agent, papermaking and drying were performed, and a 1.0 wt% hydrogel solution was impregnated and dried again to prepare a highly functional deodorized Japanese paper according to the present invention.
また、上記ハイドロゲルを使用しない消臭和紙として、硫酸バンド、デンプンのり、サイズ剤のみによって、上記ヨウ素アニオン交換樹脂、トルマリンを定着させたもの（消臭剤等の配合量は同量）を作成した。そして、これらの消臭和紙を、各々Ａ４サイズにして、水洗による定着強度の比較試験を実施した。 In addition, as the deodorized Japanese paper that does not use the hydrogel, the above iodine anion exchange resin and tourmaline are fixed only by sulfuric acid band, starch paste, and sizing agent (the same amount of deodorant etc. is added) did. These deodorized Japanese papers were each made into A4 size, and a comparative test of fixing strength by washing with water was performed.
具体的には、上記段落（００２１）で得られた高機能性消臭和紙および段落（００２２）で得られた消臭和紙を各々水洗し、水洗（水道水、流水１分）の回数による測定用サンプルの中央部から５ｃｍ×５ｃｍ角の正方形を３箇所抽出して、それぞれの場所を２００倍に拡大写真にし、黒色のヨウ素アニオン交換樹脂の個体数を目視で数えてその平均値を算出した。また、上記高機能性消臭和紙については、悪臭成分であるアンモニアについて消臭効果の評価も行った。図４は、その結果を示すものである。 Specifically, the highly functional deodorized Japanese paper obtained in the above paragraph (0021) and the deodorized Japanese paper obtained in the paragraph (0022) are each washed with water and measured by the number of times of washing (tap water, running water for 1 minute). 3 squares of 5 cm × 5 cm square were extracted from the center of the sample, and each place was magnified 200 times, and the average number of black iodine anion exchange resin was counted and the average value was calculated. . Moreover, about the said highly functional deodorizing Japanese paper, the deodorizing effect was also evaluated about ammonia which is a malodorous component. FIG. 4 shows the result.
図４に見られるように、ハイドロゲルを添加・含侵した本発明に係る高機能性消臭和紙は、水洗を１０回行った後においても、ヨウ素アニオン交換樹脂（個体）の減少が少なく、したがってアンモニアの消臭効果も９５％以上を維持することがわかった。
これに対して、比較例となるハイドロゲルを使用しない消臭和紙は、水洗によってヨウ素アニオン交換樹脂（個体）が著しく剥がれ落ちていることがわかった。
As shown in FIG. 4, the highly functional deodorized Japanese paper according to the present invention to which hydrogel is added / impregnated has little decrease in iodine anion exchange resin (solid) even after washing with
In contrast, the deodorized Japanese paper that does not use the hydrogel as a comparative example was found to have the iodine anion exchange resin (solid) significantly peeled off by washing with water.
これにより、ハイドロゲルが定着に寄与する効果は大きいことが判明した。すなわちハイドロゲルにより、水洗回数が増えても個体数の減少率が小さく、よってアンモニアの消臭効果は水洗の影響をほとんど受けずに、水に不溶性であるハイドロゲルが消臭剤を強固に安定的に定着させていることが確認できた。 As a result, it has been found that the effect of hydrogel contributing to fixing is great. In other words, the hydrogel reduces the population decrease rate even when the number of water washing increases, so the deodorizing effect of ammonia is hardly affected by water washing, and the hydrogel that is insoluble in water strongly stabilizes the deodorant. It was confirmed that it was firmly established.
次に、図２および図３に基づいて、本発明に係る高機能性消臭和紙の製造方法の他の実施形態について説明する。
この製造方法においては、図１に示した製造方法と、混練までの工程は同一である。そして、本製造方法においては、図２および図３に示すように、ヨウ素アニオン交換樹脂を配合した和紙の両面に、さらにこの和紙よりも薄い保護和紙を抄き合わせ、次いで上記保護和紙にハイドロゲル１．０wt%を含浸させて乾燥することにより、高機能性消臭和紙（３層構造）を得る。
Next, based on FIG. 2 and FIG. 3, other embodiment of the manufacturing method of the highly functional deodorizing Japanese paper which concerns on this invention is described.
In this manufacturing method, the steps up to kneading are the same as the manufacturing method shown in FIG. And in this manufacturing method, as shown in FIG. 2 and FIG. 3, the protective Japanese paper thinner than this Japanese paper is made on both sides of the Japanese paper containing iodine anion exchange resin, and then the hydrogel is applied to the protective Japanese paper. A highly functional deodorized Japanese paper (three-layer structure) is obtained by impregnating 1.0 wt% and drying.
したがって、本実施形態の上記段落（００２６）の製造方法によって得られた高機能性消臭和紙によれば、保護和紙によって、図１によって得られる高機能性消臭和紙よりも、より一段と消臭剤等の保持効果を高めることができるために、後述する実施例４から明らかなように、水洗による再生を繰り返し行っても、消臭効果を持続させたままで、長期間にわたって使用することが可能になる。 Therefore, according to the highly functional deodorized Japanese paper obtained by the manufacturing method of the above paragraph (0026) of the present embodiment, the protective Japanese paper further deodorizes the high functional deodorized Japanese paper obtained by FIG. Since the retention effect of the agent and the like can be enhanced, as will be apparent from Example 4 described later, even if the regeneration by washing with water is repeated, the deodorizing effect is maintained and it can be used over a long period of time. become.
本発明の具体的な効果を実証するために、トイレ、冷蔵庫、台所、室内の代表的な家庭内の悪臭成分であるアンモニア、酢酸、硫化水素の３種類を対象とする悪臭として選定し、これらの悪臭に対して、外部の専門検査機関である財団法人日本繊維製品品質技術センターにて消臭効果とその持続性を評価、確認するための消臭試験を行った。 In order to demonstrate the specific effects of the present invention, it is selected as a bad odor targeting three types of ammonia, acetic acid, and hydrogen sulfide, which are typical odor components in the toilet, refrigerator, kitchen, and room. The deodorization test was conducted to evaluate and confirm the deodorization effect and its sustainability at the Japan Textile Products Quality Technology Center, an external specialized inspection organization.
本発明に係る実施例および比較例ともに、消臭試験の試料の寸法は、１０×１０ｃｍであり、消臭効果の試験は、５００ｍｍＬ容器内の２時間後における悪臭残存濃度のガス検知管式測定にて行った。また、持続性については、所定の初期ガス濃度とされた袋内に試料を保管して、一定期間経過後における当該ガスの残存率によって検証した。さらに、アンモニアおよび酢酸については、水洗による耐久評価試験も行った。 In both the examples and comparative examples according to the present invention, the size of the sample for the deodorization test is 10 × 10 cm, and the test for the deodorization effect is a gas detector tube type measurement of the malodor residual concentration after 2 hours in a 500 mmL container. I went there. Further, the sustainability was verified by storing the sample in a bag having a predetermined initial gas concentration and verifying the residual rate of the gas after a certain period of time. Further, for ammonia and acetic acid, a durability evaluation test by washing with water was also performed.
（実施例１）アンモニア（初期ガス濃度：１００ｐｐｍ）に対して
図５は、本発明に係る実施例１−１〜７及び比較例１−１〜５は消臭効果及びその水洗効果を検証した試験結果である。なお、消臭効果は、消臭対象ガスの残存率（％）で表しており、いずれも、上記ガス検知管式測定によって検証した消臭効果の結果である。
(Example 1) With respect to ammonia (initial gas concentration: 100 ppm) FIG. 5 shows Examples 1-1 to 7 and Comparative Examples 1-1 to 5 according to the present invention, which verified the deodorizing effect and its water washing effect. It is a test result. The deodorizing effect is represented by the residual rate (%) of the deodorizing target gas, and both are the results of the deodorizing effect verified by the gas detector tube measurement.
これらの結果から、本発明に係る実施例１−１〜４は、ハイドロゲルを定着に用いていない比較例１−１〜２と比較して、消臭効果に優れていることが判る。
また、実施例１−３〜４と比較例１−４との対比から、トルマリンを配合することにより、比較的に持続安定性のある消臭効果が得られることが確認できる。
なお、上記の消臭剤の長期活性化と消臭和紙の持続安定を補助するための助剤として、別名「電気石」として知られている天然素材のトルマリンを用いているが、図５比較例１−４〜５からも分るように、水洗回数の少ない半年程度の短期間使用の場合には、特にこの助剤を使用しなくても、当該消臭効果に著しく大きな影響を及ぼすもりではない。
From these results, it can be seen that Examples 1-1 to 4 according to the present invention are superior in deodorizing effect as compared with Comparative Examples 1-1 and 2 in which hydrogel is not used for fixing.
Moreover, it can confirm that the deodorizing effect with comparatively long-lasting stability is acquired by mix | blending tourmaline from contrast with Examples 1-3 to 4 and Comparative Example 1-4.
In addition, although the tourmaline of a natural material known as “Turning stone” is used as an auxiliary agent for assisting the long-term activation of the deodorant and the sustained stability of the deodorized Japanese paper, a comparison with FIG. As can be seen from Examples 1-4 to 5, in the case of short-term use of about half a year with a small number of washings, the deodorizing effect may be significantly affected even if this auxiliary is not used. is not.
また、実施例１−５〜７は、実施例１−４同等品の水洗効果を検証したものである。一定期間(約２ケ月間)使用した後に水洗することにより、消臭効果が作成時に近い値にまで復元していることが確認できる。
なお、実施例１−５と１−７のアンモニア残存結果より、浸し水による水洗は１分間で消臭効果の持続性が高いことが確認できた。
Examples 1-5 to 7 verify the water washing effect of the equivalent product of Example 1-4. By washing with water after using for a certain period (about 2 months), it can be confirmed that the deodorizing effect has been restored to a value close to that at the time of creation.
In addition, from the ammonia remaining results of Examples 1-5 and 1-7, it was confirmed that the washing with the immersion water had a high deodorizing effect in 1 minute.
（実施例２）酢酸（初期ガス濃度:５０ｐｐｍ）に対して
図６は、本発明に係る実施例２−１〜５および比較例２−１〜３の消臭効果を検証した試験結果である。なお、消臭効果は、実施例１と同様に、消臭対象ガスの残存率（％）で表しており、いずれも、上記ガス検知管式測定によって検証した消臭効果の結果である。
(Example 2) For acetic acid (initial gas concentration: 50 ppm) FIG. 6 is a test result verifying the deodorizing effect of Examples 2-1 to 5 and Comparative Examples 2-1 to 3 according to the present invention. . In addition, the deodorizing effect is represented by the residual rate (%) of the deodorizing target gas, as in Example 1, and both are the results of the deodorizing effect verified by the gas detector tube measurement.
これらの結果から、酢酸についても、本発明に係る実施例２−１〜３によれば、ハイドロゲルを定着に用いていない比較例２−１〜２と比較して、消臭効果に優れていることが判る。 From these results, according to Examples 2-1 to 2-3 according to the present invention, acetic acid is superior in deodorizing effect as compared with Comparative Examples 2-1 and 2 that do not use hydrogel for fixing. I know that.
また、実施例２−４〜５は、実施例２−３同等品の水洗効果を検証したものであり、一定期間（約２ヶ月間）保管した後に水洗することにより、水洗しない場合（実施例２−３）と比較して、消臭効果がかなり回復していることが確認できる。 In addition, Examples 2-4 to 5 are those in which the water washing effect of the equivalent product of Example 2-3 was verified, and when washed for a certain period (about 2 months) and then washed with water (Example) Compared with 2-3), it can be confirmed that the deodorizing effect is considerably recovered.
（実施例３）硫化水素（初期ガス濃度：４ｐｐｍ）に対して
図７は、本発明に係る実施例３−１〜７の消臭効果を検証した試験結果である。なお、消臭効果は、実施例１と同様に、消臭対象ガスの残存率（％）で表しており、いずれも、上記ガス検知管式測定によって検証した消臭効果の結果である。
図７の硫化水素残存率の結果から、ハイドロゲル、消臭剤、トルマリンの各々の配合割合が同一である図５（アンモニア初期ガス濃度 １００ｐｐｍ）の実施例１−１〜２、図６（酢酸初期ガス濃度 ５０ｐｐｍ）の実施例２−１〜２、図７（硫化水素初期ガス濃度 ４ｐｐｍ）の実施例３−１〜２を比べると、当該消臭剤の消臭効果すなわち悪臭ガス分解の選択制は、大きい順にアンモニア、酢酸、硫化水素であることが判る。また、実施例３−６〜７による硫化水素残存率の大きな減少結果により、むしろ消臭効果の寄与は、消臭剤の増量効果が大きく影響していることが判る。
(Example 3) With respect to hydrogen sulfide (initial gas concentration: 4 ppm) FIG. 7 is a test result in which the deodorizing effect of Examples 3-1 to 7 according to the present invention was verified. In addition, the deodorizing effect is represented by the residual rate (%) of the deodorizing target gas, as in Example 1, and both are the results of the deodorizing effect verified by the gas detector tube measurement.
From the results of the hydrogen sulfide residual rate in FIG. 7, Examples 1-1 and 2 in FIG. 5 (initial ammonia gas concentration of 100 ppm) and FIG. 6 (acetic acid) in which the blending ratios of hydrogel, deodorant, and tourmaline are the same. Comparing Examples 2-1 and 2 with an initial gas concentration of 50 ppm) and Examples 3-1 and 2 with FIG. 7 (hydrogen sulfide initial gas concentration of 4 ppm), the deodorant effect of the deodorant, that is, selection of malodorous gas decomposition It can be seen that ammonia, acetic acid, and hydrogen sulfide are in descending order. Moreover, it turns out that the contribution of the deodorizing effect is largely influenced by the effect of increasing the deodorizing agent, from the result of the large decrease in the hydrogen sulfide residual rate according to Examples 3-6 to 7.
（実施例４）３層構造にすることの効果
図１に示した製造方法によって得られる高機能性消臭和紙（以下、１層と略す。）と、図２および図３に示した和紙の両面に薄い保護和紙を抄き合せて一体化させた高機能性消臭和紙（以下、３層と略す。）を用い、それぞれ水道水に１分間浸けること（浸け水）を繰り返し行う水洗の耐久評価試験を実施した。
(Example 4) Effect of having a three-layer structure The highly functional deodorized Japanese paper (hereinafter abbreviated as one layer) obtained by the manufacturing method shown in FIG. 1 and the Japanese paper shown in FIG. 2 and FIG. Durability of water washing using high-performance deodorized Japanese paper (hereinafter abbreviated as 3 layers) that is made by integrating thin protective Japanese paper on both sides and repeatedly soaking in tap water (soaking water) for 1 minute each. An evaluation test was conducted.
評価方法は、実施例１に示したものと同様に、初期ガス濃度が１００ｐｐｍのアンモニアガスを用いて、５００ｍｍＬ容器内の２時間後における悪臭残存濃度のガス検知管式測定により実施した。１層および３層の高機能性消臭和紙は、いずれもヨウ素アニオン交換樹脂８．０wt%、トルマリン４．０wt%、ハイドロゲル１．０wt%である。 In the same manner as shown in Example 1, the evaluation method was carried out by using a gas detector tube type measurement of the malodor residual concentration after 2 hours in a 500 mmL container using ammonia gas having an initial gas concentration of 100 ppm. The 1-layer and 3-layer highly functional deodorized Japanese paper are 8.0% by weight iodine anion exchange resin, 4.0% by weight tourmaline, and 1.0% by weight hydrogel.
この試験は、水洗による再使用によって１年間継続して消臭効果を発揮させるために、５回の水洗を想定して行った。さらに、再使用の回数を、１年以上の使用も想定し、１０回の水洗による消臭効果の確認も実施した。
図８は、この結果を示すもので、特に３層とした高機能性消臭和紙によれば、水洗１０回の強固な定着が確認できたことから、当該水洗を行うことにより約２年間の安定的な消臭効果が期待されることが実証された。
This test was conducted on the assumption that the water was washed five times in order to continuously exhibit the deodorizing effect for one year by reuse by washing with water. Furthermore, the deodorizing effect by 10 times of water washing was also confirmed, assuming that the number of times of reuse is one year or more.
FIG. 8 shows this result. In particular, according to the highly functional deodorant Japanese paper having three layers, it was confirmed that the solid fixing was performed ten times with water washing. It was proved that a stable deodorizing effect is expected.
前記のとおり、消臭剤のヨウ素アニオン交換樹脂がアンモニア、酢酸及び硫化水素の家庭内悪臭成分を分解消臭できることが確認できた。しかし、その実効性として重要な要素の一つである速効性の大きさについては、図５の実施例１−４、図６の実施例２−３及び図７の実施例３−６の結果より、速効性が大きい順にアンモニア、酢酸、硫化水素であることが判り、いずれも、実用化可能な大きな消臭効果が確認できた。 As described above, it was confirmed that the iodine anion exchange resin as a deodorant can eliminate the malodorous components in the home of ammonia, acetic acid and hydrogen sulfide. However, the magnitude of the rapid effect, which is one of the important factors as its effectiveness, is the result of Example 1-4 in FIG. 5, Example 2-3 in FIG. 6, and Example 3-6 in FIG. From the results, it was found that ammonia, acetic acid, and hydrogen sulfide were in order of increasing fast-acting properties.
