Description
本発明は有害生物忌避シートまたは紙状物にかかり、更に詳しくは、植物であるクララの靭皮繊維あるいはクララから得られるシバンムシ忌避成分を使用する有害生物忌避シートまたは紙状物に関する。 The present invention relates to a pest repellent sheet or paper-like material, and more particularly to a pest repellent sheet or paper-like material using a clam bast fiber of plants or a beetle repellent component obtained from Clara.
文化遺産は、我が国の長い歴史の中で生まれ、今日の世代に守り伝えられてきた貴重な国民的財産である。我が国の歴史、文化等の正しい理解のために欠くことのできないものであると同時に、将来の文化の発展の基礎をなすものであり、後世に残すべきものである。 Cultural heritage is a precious national asset that was born in Japan's long history and has been protected and passed down to today's generation. It is indispensable for the correct understanding of Japan's history, culture, etc., and at the same time it forms the basis for future cultural development and should be left to future generations.
文化遺産として身近なものに、絵画、古文書、書籍、典籍、考古資料、歴史資料等の美術工芸品がある。我が国には、美術工芸品に害を及ぼす昆虫の種類が多く、喰入による被害が発生する。例えば、シロアリ類、シバンムシ類、カツオブシムシ類、ナガシンクイムシ類による文化遺産への加害が知られている。特にシバンムシ類は靭皮繊維や木質繊維の主成分であるセルロースとヘミセルロースを栄養源にすることにより、これら美術工芸品の生物的劣化の主要因となる。 Among the familiar cultural heritage are arts and crafts such as paintings, ancient documents, books, books, archaeological materials, and historical materials. In Japan, there are many types of insects that are harmful to arts and crafts, and damage caused by encroachment occurs. For example, the damage to cultural heritage by termites, hornworms, cutlet worms, and longhorn beetles is known. Shivanmushi, in particular, becomes the main cause of biological deterioration of these arts and crafts by using cellulose and hemicellulose, which are the main components of bast fibers and wood fibers, as nutrient sources.
虫害が発生した場合には、被害の進行を停止させることが肝要である。具体的には殺虫剤の使用が考えられる。しかし美術工芸品に殺虫剤を散布したり塗布したりすると、美術工芸品に悪影響を与える可能性があるだけでなく、作業者の健康等にも悪影響を及ぼす恐れが大きい。 When insect damage occurs, it is important to stop the progress of the damage. Specifically, the use of insecticides can be considered. However, spraying or applying insecticides to arts and crafts not only has a negative impact on arts and crafts, but also has a high risk of adversely affecting the health of workers.
薬剤の散布や塗布に代えて、燻蒸による処置が施される場合がある。この処置は、美術工芸品をシートなどで覆った密閉空間や室内に臭化メチル、弗化サルフリルなどのガスを満たして行われる。燻蒸の場合は薬の成分が残存しないため作品への悪影響は抑えられるといわれているが、期間経過後の悪影響については必ずしも明らかではない。また、燻蒸処置後も、虫害が発生するおそれがあり、充分ということはできない。 In some cases, treatment by fumigation may be performed instead of spraying or applying medicine. This treatment is performed by filling a closed space or room covered with a sheet of arts and crafts with a gas such as methyl bromide or sulfuryl fluoride. In the case of fumigation, it is said that the adverse effects on the work can be suppressed because the ingredients of the medicine do not remain, but the adverse effects after the lapse of time are not necessarily clear. In addition, there is a risk of insect damage after fumigation treatment, and it cannot be said that it is sufficient.
然るにこれまで広く使われてきた臭化メチルは劇毒物であり、1997年に開催されたモントリオール議定書契約国会合においてオゾン層破壊物質に指定され、2005年からその生産と使用が全廃されるに至っており、文化遺産の虫害防除に使用できなくなっている。 However, methyl bromide, which has been widely used so far, is a toxic toxic substance, and was designated as an ozone-depleting substance at the Montreal Protocol Contracting Conference held in 1997, and its production and use have been abolished since 2005. It can no longer be used to control insect damage on cultural heritage.
文化遺産を虫害から保護することは、文化遺産を後世に残すためにも重要である。
本発明者等は、人体に対して安全であり、環境に対する負荷も低い新規な文化遺産の保存技術を開発するべく研究を重ね、薬草植物、特にその中でも、マメ科の植物の一種であるクララ（Sophora flavescens Aiton）に着目した。
Protecting cultural heritage from insect damage is also important for leaving cultural heritage for future generations.
The inventors of the present invention have conducted research to develop a technique for preserving a new cultural heritage that is safe for the human body and has a low environmental impact, and is a herbaceous plant, especially Clara, which is a kind of leguminous plant. We focused on (Sophora flavescens Aiton).
マメ科植物のクララは、マトリン(matrine)とオキシマトリン(oxymatrine)を含むキノリジジンアルカロイド（quinolizidine alkaloid）を含んでいる。クララの根は、苦参（くじん）という生薬であり、日本薬局方に収録されている。消炎、鎮痒作用、苦味健胃作用があり、苦参湯（くじんとう）、当帰貝母苦参丸料（とうきばいもくじんがんりょう）などの漢方方剤に配合される。このような薬効をもつクララは、特許文献１に示すように虫忌避剤の一成分として使用されている。
The legume Clara contains quinolizidine alkaloids including matrine and oxymatrine. The roots of Clara are herbal medicines called Kujin and are recorded in the Japanese Pharmacopoeia. It has anti-inflammatory, antipruritic, and bitter tasteful stomach effects, and is formulated in Chinese herbal medicines such as bitter hot water and tokikai mom gangan-maru. Clara having such a medicinal effect is used as a component of an insect repellent as disclosed in
特許文献１に記載された虫忌避剤は、クララから薬効成分を抽出したものであり液状である。このため使用に当たっては、美術工芸品に対して直接に散布や塗布などの使用が考えられる。しかし、美術工芸品に対する直接の散布や塗布は、美術工芸品に悪影響を与える可能性を排除できない。特に紙状物工芸品に適用し難い。
The insect repellent described in
ところで、長期保存を必要とする記録紙や絵画の画紙などは、それ自体が虫害を回避できるのが好ましい。また、シートや紙状物は、ものを被覆したり包装したりするのに便利であり、広範囲に使用できる。
しかし、特許文献１記載の虫忌避剤は液状であり、使用範囲は限定される。
By the way, it is preferable that recording paper and painting paper that require long-term storage can themselves avoid insect damage. Sheets and papers are convenient for covering and packaging things and can be used in a wide range.
However, the insect repellent described in
本発明者等は、クララの繊維についても忌避効果を有するのであれば、それを原料としてシートまたは紙状物を形成し、これを長期保存を必要とする美術工芸品の被覆或いは包装材として使用することによって、シロアリ類、シバンムシ類、カツオブシムシ類、ナガシンクイムシ類等の有害生物の喰入による被害からから美術工芸品を守ることが可能となることに着目し、下記に説明するように数々の実験を試みた。 If the present inventors also have a repellent effect on Clara fibers, they form a sheet or paper-like material as a raw material and use it as a covering or packaging material for arts and crafts that require long-term storage. Focusing on the fact that it will be possible to protect arts and crafts from damage caused by the invasion of pests such as termites, beetles, cutworms, and longhorn beetles, as described below I tried an experiment.
〔実験１〕
図１は、雄雌各７匹のシバンムシ成虫に楮繊維とクララの靭皮繊維（共に脱水した半乾燥繊維）を各々0.05ｇを与えて、ガラス容器で飼育した結果である。クララの靭皮繊維を与えた容器内では2日後に12匹が死亡し、6日後に全個体が死亡した。
これに対して、楮繊維では6日後までは全14匹が生存し、その後も死亡は漸次に推移し、18日後にも生存している個体があった。
このように、クララの靭皮繊維には、有害生物の忌避効果だけでなく、殺虫効果もあることが確認できた。
[Experiment 1]
FIG. 1 shows the results of feeding each 7 male and female adult beetles with 0.05 g each of cocoon fiber and Clara 's bast fiber (both dehydrated semi-dry fibers) and raising them in glass containers. Twelve died after 2 days and all individuals died after 6 days in the container fed Clara 's bast fiber.
On the other hand, in sputum fibers, all 14 animals survived until 6 days, and then the death gradually changed, and some individuals survived 18 days later.
Thus, it was confirmed that Clara 's bast fiber has not only a pest repellent effect but also an insecticidal effect.
〔実験２〕
表１は、雄雌各７匹のシバンムシ成虫にクララの各部位と他の植物繊維を与えた容器内でシバンムシ成虫が経過日数に応じた生存個体数を測定した結果で、図１のデータも含めたものである。なお、クララは、木質部（根の芯髄）と根茎の未処理の丸太を加えて比較した。
[Experiment 2]
Table 1 shows the results of measuring the number of surviving individuals according to the number of days that the adult beetle was present in a container in which each of 7 male and female beetles was given each part of Clara and other plant fibers. It is included. In addition, Clara was compared by adding a woody part (root core) and an untreated log of rhizome.
表１に示すように、クララの靭皮繊維での急激な死亡に対比して、対照区とした楮や牛蒡の繊維では14日後まで全体の30％前後の個体が生存した。クララの他の部位では次第に生存個体が減少し、14日経過でも生存している個体があり、クララの靭皮繊維に含まれる成分の殺虫効果が際だって高いことが確認できた。 As shown in Table 1, in contrast to the sudden death of Clara 's bast fibers, about 30% of the individuals survived up to 14 days after the 14th day of the cocoon and cowpox fibers used as the control. In other parts of Clara, the number of surviving individuals gradually decreased, and some individuals survived even after 14 days. It was confirmed that the insecticidal effect of the components contained in Clara 's bast fibers was remarkably high.
〔実験３〕
乾燥した楮繊維、牛蒡繊維、クララ繊維、及び生のクララの靭皮繊維、芯髄木質、そして根茎そのままを飼育容器の底面に置き、シバンムシ成虫の行動を記録した。その結果を図２に示す。
図２から明らかなように、楮繊維と牛蒡繊維では繊維のある底面と側面や上面とに分布の差異は認められなかった。一方、クララ繊維、生のクララの靭皮繊維、芯髄木質、根茎全体に対してシバンムシは明らかに底面より側面や上面に位置するという忌避効果が顕著に現れている。
[Experiment 3]
Dried mulberry fiber, burdock fibers placed Clara fibers, and raw Clara bast fibers, Shinzui wood and rhizomes directly to the bottom surface of the rearing container was recorded the behavior of beetles adult. The result is shown in FIG.
As apparent from FIG. 2, no difference in distribution was observed between the bottom surface, the side surface, and the top surface of the cocoon fiber and cow cow fiber. Meanwhile, Clara fibers, bast fibers raw Clara, Shinzui wood, the repellent effect of beetles for the entire rootstock obviously located on the sides and top than the bottom surface is conspicuous.
〔実験４〕
クララの靭皮及び芯髄の沈殿物の精製粉末と、それらを各々遠心分離した時の上清、及び、対照区として蒸留水を用いてシバンムシの回避行動について比較した。
各上清と蒸留水の0.2ml、及び靭皮と芯髄の精製粉末を上清と同比（0.1％）で蒸留水に分散した懸濁液0.2mlを個別に直径100mm、高さ10mmのシャーレに敷いたろ紙に滴下し、その滴下部位を通過するシバンムシ成虫の数を５分ごとに３０分間測定した。その結果を図３に示す。
図３から明らかなように、靭皮の懸濁液を滴下した部位を通過するシバンムシ成虫は皆無であり、各上清や蒸留水の対照区と比較して、明らかに靭皮由来の忌避成分が有する忌避効果が確認できた。
[Experiment 4]
The purified powders of Clara's bast and core pulp precipitates were compared with the supernatants obtained by centrifuging them, and distilled water was used as a control group, and the avoidance behavior of the beetles was compared.
Each supernatant and 0.2 ml of distilled water, and 0.2 ml of a suspension containing purified bast and core pulp powder in distilled water at the same ratio (0.1%) as the supernatant, were individually Petri dishes with a diameter of 100 mm and a height of 10 mm. The number of adult beetles that passed through the dropping site was measured every 5 minutes for 30 minutes. The result is shown in FIG.
As is apparent from FIG. 3, there is no adult beetle that passes through the site where the suspension of the bast is dripped, and it is clearly a repellent component derived from the bast compared with the control group of each supernatant and distilled water. The repellent effect of can be confirmed.
以上の実験結果から、本発明者等は、クララの靭皮繊維およびクララの靭皮繊維から得られる忌避成分にはシバンムシの忌避又は殺虫効果があり、これを使用して生成したシートまたは紙状物は、それ自体が虫害を回避できるばかりでなく、美術工芸品の包装材として使用することができ、広範囲な使用が可能であることを知見し、本発明を完成するに至った。 From the above experimental results, the present inventors have, the repellent component obtained from the bast fibers and Clara bast fibers Clara have repellent or insecticidal effect of beetles, resulting sheets or paper-like and used to The product itself can not only prevent insect damage but also can be used as a packaging material for arts and crafts, and it has been found that it can be used in a wide range, and the present invention has been completed.

本発明では、クララの靭皮繊維を使用する。クララの靭皮繊維は根、茎、葉に含まれている。使用する部位は根、茎、葉のいずれでも良く、異なる部位の繊維を混ぜ合わせてもよい。なお、表１から理解されるように、忌避或いは殺虫効果の観点からは、茎の周辺部から取れる靭皮繊維が好ましい。 In the present invention, Clara bast fibers are used. Clara 's bast fibers are found in roots, stems and leaves. The part to be used may be any of roots, stems, and leaves, and fibers of different parts may be mixed. As can be seen from Table 1, bast fibers that can be taken from the periphery of the stem are preferred from the viewpoint of repellent or insecticidal effects.
クララの靭皮繊維は、外樹皮と芯部木質髄の導管部との間にある内樹皮の篩部繊維組織に由来する。薄い外樹皮を除去し、木質髄を取り巻く厚い内樹皮を剥離して繊維を取り出して乾燥した後、通常の和紙原料と同様にアルカリ性溶液下で煮熟、叩解、灰汁抜きして中性の繊維とする。 Clara's bast fibers are derived from the sieving fibrous tissue of the inner bark between the outer bark and the conduit of the core wood pulp. After removing the thin outer bark, peeling off the thick inner bark surrounding the wood pulp, taking out the fiber and drying it, boiled it in an alkaline solution, boiled it, beaten it, and removed the lye to remove neutral fiber. And
本発明では、シバンムシ忌避成分としてクララの靭皮繊維粉末を使用する。クララの靭皮繊維粉末は下記のような工程で得られる。
生のクララの根茎を洗い、細根と外皮を除去した後、内樹皮と芯髄を分離して内樹皮のみをミキサー等の破砕機に入れ，原料１重量部に対して5〜10重量部の蒸留水を加えて粉砕するとクララの靭皮繊維粉末を分散した懸濁液が得られる。
この懸濁液を遠心分離(例えば3000 rpm, 10分)するか，あるいは数時間放置するとクララの靭皮繊維粉末は、沈殿物として上清と分離して底に沈殿する。上清を除いた後、沈殿物を脱水乾燥して、粉末として精製されたクララの靭皮繊維粉末（抽出物）を得る。通常、原料であるクララ根茎の８〜１２％(重量％)のクララの靭皮繊維粉末が得られる。
In the present invention, a bast fiber powder Clara as beetles repellent component. Clara 's bast fiber powder is obtained by the following process.
After washing the raw Clara rhizomes, removing the fine roots and hulls, separating the inner bark and core pulp and putting only the inner bark into a crusher such as a mixer, 5-10 parts by weight per 1 part by weight of the raw material When distilled water is added and pulverized, a suspension in which Clara 's bast fiber powder is dispersed is obtained.
When this suspension is centrifuged (for example, 3000 rpm, 10 minutes) or allowed to stand for several hours, Clara 's bast fiber powder separates from the supernatant as a precipitate and precipitates at the bottom. After removing the supernatant, the precipitate is dehydrated and dried to obtain a clara bast fiber powder (extract) purified as a powder. Usually, 8 to 12% (weight%) of Clara bast fiber powder of Clara rhizome as a raw material is obtained.
本発明で使用する和紙は、楮、雁皮、三椏の靭皮繊維を原料とする一般的なものであり、日本工業規格用語で定義された抄紙である。その工程は公知であるから詳細な説明は省略するが、内樹皮のアルカリ性溶液下による煮熟工程−ちり取り工程−打解（叩解）工程により、原料に含まれる不純物を水に溶け出す作業を経て繊維のみを取り出す。次に抄紙工程において漉き桁または抄紙機により紙料（原料）を均等に分散して層状にする。 The Japanese paper used in the present invention is a general paper made from cocoon, husk, and three-kind bast fiber, and is a papermaking defined in Japanese Industrial Standard terms. Since the process is well known, detailed description is omitted, but the work of dissolving the impurities contained in the raw material in water by the ripening process under the alkaline solution of the inner bark, the dust removing process, and the beating (beating) process After that, only the fiber is taken out. Next, in the paper making process, the paper stock (raw material) is evenly dispersed and layered by a handing girder or a paper machine.
和紙にクララの靭皮繊維やクララの靭皮繊維粉末を混合する場合は、この抄紙工程の前に混入する。クララの靭皮繊維粉末を楮等の原紙料に適量を分散させ、漉き作業を行う。
つまり、一般的な和紙の製造工程中の紙漉工程の前に紙漉工程で使用する紙料にクララの靭皮繊維粉末を混入し分散させる。
When mixing Japanese paper with Clara 's bast fiber or Clara 's bast fiber powder, it is mixed before this paper making process. Disperse an appropriate amount of Clara 's bast fiber powder in a base paper such as cocoons, and perform the operation.
In other words, Clara 's bast fiber powder is mixed and dispersed in the stock used in the papermaking process before the papermaking process in the general Japanese paper manufacturing process.
長期保存の記録紙や絵画の画紙の場合には、クララの靭皮繊維粉末のみを紙料に混入するが、被覆用包装紙の場合には、クララの靭皮繊維もクララの靭皮繊維粉末に加えて紙料に含める。 In the case of long-term recording paper or drawing paper, only Clara 's bast fiber powder is mixed into the stock, but in the case of coating wrapping paper, Clara's bast fiber is also Clara 's bast fiber. In addition to powder, include in paper.
