繊維製品を保存する際に、コイガやヒメカツオブシムシなどの繊維害虫による繊維製品の食害を防ぐために用いられる防虫剤として、従来、パラジクロロベンゼンやピレスロイド系化合物などの合成化合物を有効成分とする防虫剤が一般的に用いられてきた。しかしながら、これらの合成化合物については、その防虫剤成分としての有効性は確認されているものの、強い刺激臭を示すものが多いこと、そして化合物によっては、人体に対する安全性に疑問が持たれる化合物もあるところから、近年では、刺激臭が弱く、また人体に対する安全性も高い天然ハーブを防虫成分として用いた天然ハーブ防虫剤の使用も一般的になっている。 Insect repellents containing synthetic compounds such as paradichlorobenzene and pyrethroid compounds have traditionally been used as insect repellents to prevent the damage of fiber products caused by fiber pests such as Koga and Pleurotus cornucopia when storing the fiber products. It has been commonly used. However, although it has been confirmed that these synthetic compounds are effective as insect repellent components, many of them have a strong irritating odor, and depending on the compound, some compounds have a doubt on the safety to human body. From a certain point of view, in recent years, the use of natural herb repellents using natural herbs as insect repellents, which have a weak irritating odor and are highly safe for the human body, has also become common.
特許文献１には、コイガやヒメカツオブシムシなどの繊維害虫が、ユーカリ油とメントン油との２０：８０乃至８０：２０の混合物（精油混合物）に対して忌避行動を示すとの確認結果に基づく発明として、その精油混合物をプロピレングリコールなどのグリコールで表面処理した粒状担体に坦持させて調製した防虫剤が開示されている。粒状担体の例としては、シリカゲルやセルロースビーズが記載されているが、なかでも、調湿効果のあるシリカゲルが推奨されている。ただし、複数種知られているシリカゲルの内のどのようなタイプのものの使用が可能であるか、あるいは好ましいかの点についての開示は一切見られず、またシリカゲルの粒径に関する記載は見られない。さらに当該防虫剤を袋体に収容して用いることの記載もない。 Patent Document 1 discloses an invention based on the result of confirmation that fiber pests such as Koga and Pleurotus cornucopiae show repellent behavior against a mixture of 20:80 to 80:20 eucalyptus oil and menthol oil (essential oil mixture). As an insect repellent prepared by supporting the essential oil mixture on a granular carrier surface-treated with glycol such as propylene glycol. Although silica gel and cellulose beads are described as examples of the granular carrier, among them, silica gel having a humidity control effect is recommended. However, there is no disclosure as to what type of silica gel known among a plurality of types can be used or preferred, and no description about the particle size of silica gel is found. . Further, there is no description of using the insect repellent in a bag.
特許文献２には、多くの香油成分に含まれるエーテル結合を有する炭素数１０個の環式化合物を有効成分とする防虫剤が開示されている。そして、この防虫剤を濾紙あるいは布製小袋に包んだ防虫剤包装体としての使用の例の記載がある。また、防虫剤が油性物質であることを考慮して、これをタルク、シリカゲル、パルプマット、濾紙に吸着させて使用することの記載もある。しかしながら、タルクやシリカゲルなどの粒状担体に関しては、それ以上の詳しい記載は見られない。 Patent Document 2 discloses an insect repellent containing, as an active ingredient, a cyclic compound having an ether bond and having 10 carbon atoms, which is contained in many perfume oil components. Then, there is a description of an example of using this insect repellent as a insect repellent package which is wrapped in a filter paper or a cloth pouch. There is also a description that the insect repellent is an oily substance, and is used by adsorbing it on talc, silica gel, pulp mat, or filter paper. However, no further detailed description is found regarding granular carriers such as talc and silica gel.
特許文献３には、メントンを有効成分として含有する防虫剤が開示されいる。そして、メントンが粘ちょうな液体であることを考慮して、このメントンをペーパーボードやゼオライトのような担体に含浸させ、通気性のある和紙の袋やプラスチックまたは防湿セロファン等に適宜小孔を穿った袋に収容することの記載がある。 Patent Document 3 discloses an insect repellent containing menthone as an active ingredient. Considering that menthone is a viscous liquid, it is impregnated with a carrier such as paper board or zeolite, and small holes are appropriately punched in a breathable Japanese paper bag, plastic, or moisture-proof cellophane. There is a description that it will be stored in a bag.
特許文献４には、クロルピリフォスを有効成分とし、シリカゲル、プロピレングリコール及びアクリルポリマーが混合されていなる害虫駆除塗布剤が開示されている。この害虫駆除塗布剤は、建造物の床、畳床、壁、家具あるいはカーペット等に塗布されて使用される防虫剤であり、従って、防虫剤を袋体に収容して用いることの記載はなく、またシリカゲルのタイプや粒度に関する記載も見られない。 Patent Document 4 discloses a pest control composition containing chlorpyrifos as an active ingredient and containing silica gel, propylene glycol and an acrylic polymer mixed therein. This pest control agent is an insect repellent that is used by being applied to floors, tatami floors, walls, furniture, carpets, etc. of buildings, and therefore there is no description of using the repellent in a bag.

ただし、特許文献１には、前述のように、本発明の天然ハーブ防虫剤包装体の天然ハーブ防虫剤の構成材料であるＢ型シリカゲル粒子についての記載が見られないので、以下に詳しく説明する。 However, as described above, Patent Document 1 does not describe the B-type silica gel particles that are the constituent material of the natural herb repellent of the natural herb repellent package of the present invention, and thus will be described in detail below. .
シリカゲル粒子は、単にシリカゲルとも呼ばれる化成品であって、ケイ酸のコロイド溶液を凝固させることにより生成する粒状物であり、ＪＩＳでは、主として吸湿率の違いに着目して、Ａ型タイプのシリカゲル（Ａ型シリカゲルあるいはシリカゲルＡとも呼ばれる）とＢ型タイプのシリカゲル（Ｂ型シリカゲルあるいはシリカゲルＢとも呼ばれる）とに分類されている。Ａ型シリカゲルは、Ｂ型シリカゲルに比較して、１ｇ当たりの細孔の表面積が大きいことが特徴の一つであって、食品の包装用乾燥剤、あるいは電子製品、精密部品、光学機器、医薬品などの湿害防止用乾燥剤として一般的に使用されている。一方、Ｂ型シリカゲルは、Ａ型シリカゲルに比較して細孔の径が大きいことが特徴の一つであって、主に楽器、船舶、床下調湿、家庭用調湿などの用途に用いられている。 Silica gel particles are chemical products that are also simply called silica gel, and they are particles produced by solidifying a colloidal solution of silicic acid. In JIS, mainly focusing on the difference in moisture absorption rate, A type silica gel ( It is classified into A type silica gel or silica gel A) and B type silica gel (also called B type silica gel or silica gel B). One feature of A-type silica gel is that the surface area of pores per gram is larger than that of B-type silica gel, and it is a desiccant for food packaging, or electronic products, precision parts, optical devices, pharmaceuticals. It is generally used as a desiccant for preventing moisture damage. On the other hand, B-type silica gel has one of the characteristics that it has a larger pore size than A-type silica gel, and is mainly used for musical instruments, ships, underfloor humidity control, household humidity control, etc. ing.
本発明の発明者は、上述のＡ型シリカゲルとＢ型シリカゲルの特性を比較検討した結果、本発明の天然ハーブ防虫剤の製造に際しては、シリカゲルに坦持させる香気成分を含む精油混合物は粘性の高い油性物質であることから、その効果的な坦持のためには、表面積の大きなＡ型シリカゲルよりも、細孔の径が大きいＢ型シリカゲルを用いることが有利であろうと推測し、担体として、このＢ型シリカゲルを用いて天然ハーブ防虫剤を調製したところ、推測通り、Ｂ型シリカゲルは、精油混合物を粒子内部に高濃度に吸着あるいは収容し、その結果、粒子表面がべとつくことがなく、かつ長期にわたる天然ハーブ防虫剤の使用においても、その香気成分の保持が可能であることを確認した。 The inventor of the present invention conducted a comparative examination of the characteristics of the above-mentioned A-type silica gel and B-type silica gel, and as a result, in the production of the natural herb repellent of the present invention, an essential oil mixture containing an aroma component to be carried on silica gel was viscous Since it is a highly oily substance, it is presumed that it is more advantageous to use B-type silica gel having a larger pore size than A-type silica gel having a large surface area for effective support, and as a carrier. A natural herb repellent was prepared using this B-type silica gel, and as expected, the B-type silica gel adsorbs or stores the essential oil mixture inside the particles in a high concentration, and as a result, the particle surface does not become sticky. It was also confirmed that the aroma component can be retained even when the natural herb repellent is used for a long time.
本発明の発明者は、さらにＢ型シリカゲルの粒度分布が天然ハーブ防虫剤の防虫性能（害虫忌避性能）に与える影響を調べる目的で研究を続けた。そして、その結果、目開き２．３６ｍｍの標準篩を通過するような微細粒子を６０質量％以上含有する天然ハーブ防虫剤が得ることのできる微細なＢ型シリカゲル粒子を精油混合物の担体として用いて製造した天然ハーブ防虫剤は、防虫成分として有効な香気成分が適量透過する袋体に収容した製品形態の天然ハーブ防虫剤包装体として、タンスや戸棚あるいは衣装函などの繊維製品収納具内に、例えば、半年（６ヶ月）というような長期にわたって使用（配置）した場合でも、その香気成分の継続的な発散が継続し、従って、繊維害虫忌避効果を有効に持続することを確認した。 The inventor of the present invention further continued the research for the purpose of investigating the influence of the particle size distribution of B-type silica gel on the insect repellent performance (pest repellent performance) of the natural herb repellent. Then, as a result, fine B-type silica gel particles from which a natural herb repellent containing 60% by mass or more of fine particles capable of passing through a standard sieve having an opening of 2.36 mm can be obtained are used as a carrier for an essential oil mixture. The produced natural herb insect repellent is a natural herb insect repellent package in the form of a product that is contained in a bag through which an appropriate amount of aroma components effective as insect repellents permeate, in a textile product storage device such as a closet or a closet or a clothes box. For example, it was confirmed that even when it was used (placed) for a long period of time such as half a year (6 months), the fragrance component continued to be diffused, and thus the fiber pest repellent effect was effectively maintained.
なお、上述した微細なＢ型シリカゲル粒子は、精油混合物の坦持作業や袋体への収容作業の効率を考慮すると、過度に微細な粒子を多く含むことは不利になるため、目開き２．３６ｍｍの標準篩を通過し、目開き１．７０ｍｍの標準篩を通過しない粒子を６０質量％以上含有する天然ハーブ防虫剤が生成するように粒度調整がされたＢ型シリカゲル粒子を担体として用いることが本発明の天然ハーブ防虫剤を製造するためには、最も有利であることも確認した。 The fine B-type silica gel particles described above are disadvantageous in containing too many fine particles in view of the efficiency of the work of carrying the essential oil mixture and the work of accommodating the essential oil mixture in the bag, and thus the mesh size is 2. Use as a carrier B-type silica gel particles whose particle size has been adjusted so as to produce a natural herb repellent containing 60% by mass or more of particles that pass through a 36 mm standard sieve and do not pass through a 1.70 mm standard sieve. Was also most advantageous for producing the natural herb repellent of the present invention.
本発明の天然ハーブ防虫剤包装体は、上述の天然ハーブ防虫剤を、ユーカリ油とメントン油の各々の香気成分が透過する袋体に収容して使用する。すなわち、家庭での繊維収納具内部で防虫剤を使用する場合、例えば、季節の変わり目毎（３ヶ月毎）あるいは半年毎（６ヶ月毎）に防虫剤を交換することが多いため、通常の防虫剤の有効期間（通常条件での使用での防虫効果の有効性が期待される期間）は６ヶ月とされることが多い。上述の天然ハーブ防虫剤についても、そのような有効期間を考慮すると、袋体に収容して使用することが好ましいことも確認した。ただし、袋体は、ユーカリ油とメントン油の各々の香気成分が透過する袋体である必要がある。 The natural herb repellent package of the present invention is used by containing the above-mentioned natural herb repellent in a bag body through which the aroma components of eucalyptus oil and menthol oil penetrate. That is, when an insect repellent is used inside a fiber storage device at home, for example, the insect repellent is often replaced at every season change (every three months) or every six months (every six months). The effective period of the agent (the period for which the effectiveness of the insect repellent effect under normal conditions is expected) is often 6 months. It was also confirmed that the above-mentioned natural herb repellents are preferably contained in a bag and used in consideration of such an effective period. However, the bag needs to be a bag through which the aroma components of eucalyptus oil and menthol oil permeate.
本発明の発明者は、さらに本発明の天然ハーブ防虫剤包装体の袋体を構成するシート状物の構成についても検討を重ねた。その結果、本発明の天然ハーブ防虫剤包装体は、Ｌ−ＬＤＰＥフィルム、ＬＤＰＥフィルム及びスパンボンド不織布にこの順に積層して形成した積層体シートから形成した袋体であって、Ｌ−ＬＤＰＥフィルムが内側となるように袋状とした袋体を用いる包装体として使用することが好ましいことを見出した。このような構成を持つ積層体シートを袋状にした構成して得た袋体に上述の天然ハーブ防虫剤を収容して用いることにより、袋体の内部に収容した天然ハーブ防虫剤に含まれるユーカリ油とメントン油の各々の香気成分（この香気成分が繊維害虫忌避効果をもたらす）が袋体の外部に適度な早さで発散され、かつ例えば、６ヶ月というような長期の保存でも、継続して、繊維害虫忌避効果が持続される。 The inventor of the present invention has further studied the structure of a sheet-like material that constitutes the bag of the natural herb insect repellent package of the present invention. As a result, the natural herb repellent package of the present invention is a bag formed from a laminate sheet formed by laminating an L-LDPE film, an LDPE film and a spunbonded nonwoven fabric in this order, and the L-LDPE film is It has been found that it is preferable to use it as a packaging body using a bag-shaped body which is formed in a bag shape so as to be on the inner side. By using the above-mentioned natural herb insect repellent contained in a bag obtained by forming a laminated sheet having such a structure into a bag, the natural herb repellent contained in the bag is contained. The fragrance components of eucalyptus oil and menthol oil (these fragrance components have the effect of repelling fiber pests) are released to the outside of the bag body at an appropriate speed, and continue even after long-term storage such as 6 months. Then, the fiber pest repellent effect is sustained.
なお、上記の袋体を構成する「Ｌ−ＬＤＰＥフィルム」と「ＬＤＰＥフィルム」は、それぞれ、「直鎖状低密度ポリエチレンフィルム」と「分岐低密度ポリエチレンフィルム」を意味し、それぞれの名称の製品として販売されており、各フィルム自体は市場で入手可能である。本発明の天然ハーブ防虫剤包装体の袋体で用いるシート状物は、スパンボンド不織布に、Ｌ−ＬＤＰＥとＬＤＰＥとの積層体フィルムを押し出しラミネートさせて製造したものであることが望ましい。 In addition, "L-LDPE film" and "LDPE film" which comprise the said bag means a "linear low density polyethylene film" and a "branched low density polyethylene film", respectively, and the product of each name. , And each film itself is available on the market. The sheet material used for the bag of the natural herb repellent package of the present invention is preferably manufactured by extrusion-laminating a laminated film of L-LDPE and LDPE on a spunbond nonwoven fabric.
そして、本発明の天然ハーブ防虫剤包装体の袋体では、袋体の積層体シートの総厚みが５０−２００μｍの範囲にあって、Ｌ−ＬＤＰＥフィルムの厚さが２０−４０μｍの範囲そしてＬＤＰＥフィルムの厚さが１０−３０μｍの範囲にあることが好ましく。また、スパンボンド不織布の目付が、１０−５０ｇ／ｍ２の範囲にあることが好ましい。このような積層体シートから形成した袋体を用いることが、袋体の内部に収容される天然ハーブ防虫剤の長期にわたる使用での防虫剤としての有効性の安定な確保のために望ましい。 In the bag of the natural herb insecticide package of the present invention, the total thickness of the laminated sheet of the bag is in the range of 50 to 200 μm, the thickness of the L-LDPE film is in the range of 20 to 40 μm, and the LDPE is LDPE. The thickness of the film is preferably in the range of 10-30 μm. Further, the basis weight of the spunbonded nonwoven fabric is preferably in the range of 10-50 g / m 2 . It is desirable to use a bag formed from such a laminated sheet in order to ensure stable effectiveness of the natural herb insect repellent contained in the bag as an insect repellent for long-term use.
