本発明は臭気吸着による減臭効果を有する産業資材用メッシュシートに関する。詳しく述べると、本発明のメッシュシートは、家屋、店舗、オフィスビル、商業施設、各種公共施設などの居住空間をはじめ、食品工場、化学品工場、畜産施設、水産施設、ゴミ処理施設、ゴミ集積所などにおいて、空間仕切用、壁掛け用、敷物用、天蓋用の形態で用い、使用環境における悪臭成分、及びＶＯＣ成分などの臭気成分全般に対してバランス良く濃度を減少させる減臭効果、及び経時的に人間の感知限界濃度に低減する消臭効果を有し、減臭効果が飽和状態となっても減臭効果の再生が可能かつ容易で繰り返し使用可能な臭気吸着メッシュシートと臭気吸着性能の回復方法に関する。 The present invention relates to a mesh sheet for industrial materials having a deodorizing effect due to odor adsorption. More specifically, the mesh sheet of the present invention includes residential spaces such as houses, stores, office buildings, commercial facilities, various public facilities, food factories, chemical factories, animal husbandry facilities, fishery facilities, garbage treatment facilities, garbage collection facilities. In places such as space partitions, wall hangings, rugs, and canopies, the deodorizing effect reduces the concentration in a well-balanced manner against odor components such as bad odor components and VOC components in the usage environment, and over time. It has a deodorizing effect that is reduced to the human perception limit concentration, and even if the deodorizing effect is saturated, the deodorizing effect can be regenerated and easily and repeatedly used, and the odor adsorbing mesh sheet It relates to the recovery method.
以前、本出願人は粗目織物と、粗目織物を被覆する熱可塑性樹脂層とで構成された、特定の充実率と単位表面積とを有する可撓性メッシュシートの熱可塑性樹脂層に、臭気分子に対して、物理的吸着性を有する無機多孔性物質、化学反応性を有する無機酸化・還元性物質、及び無機分解反応触媒物質などの臭気分子不活性化粒子を任意に用いることにより、体臭、ペット臭、調理臭、ゴミ臭、カビ臭などの生活臭全般を低減させる機能を付帯させたメッシュシート（特許文献１）を提案した。また特許文献２には、消臭性・難燃性布帛製造用後加工剤の第１液として、消臭剤、バインダー、架橋剤及び風合い改良剤を混合分散した水性分散液が例示され、消臭剤に、酸化亜鉛、シリカ、ゼオライト、ヒドラジン系化合物及び、スチレン−無水マレイン酸加水分解物の１種または複数種の混合物を使用することで臭気全般に対する消臭作用を得ることの組成が特許文献２に開示されている。これら特許文献１及び２では多種類の臭気分子に対応させるためには、各悪臭成分のカテゴリに応じた消臭成分や吸着性物質を満遍なく併用することを必須のものとしているが、実際は消臭成分や吸着性物質の併用種を多くするほど、これらの存在が互いに邪魔し合うこと、特に特定の臭気分子を吸着した消臭成分や吸着性物質が先に存在すると、他の消臭成分や吸着性物質の作用を阻害して、結果的に意図したような生活臭全般に対する減臭効果や消臭効果が持続して得られない問題が垣間見えてきた。 Previously, the present applicant has applied a odor molecule to a thermoplastic resin layer of a flexible mesh sheet having a specific filling rate and unit surface area, which is composed of a coarse woven fabric and a thermoplastic resin layer covering the coarse woven fabric. On the other hand, by arbitrarily using odor molecule deactivating particles such as an inorganic porous material having physical adsorptivity, an inorganic oxidizing / reducing material having chemical reactivity, and an inorganic decomposition reaction catalytic material, body odor, pet The mesh sheet (patent document 1) which attached the function to reduce the whole life odors, such as an odor, cooking odor, garbage odor, and mold odor, was proposed. Patent Document 2 exemplifies an aqueous dispersion in which a deodorant, a binder, a crosslinking agent, and a texture improver are mixed and dispersed as the first liquid of a post-processing agent for producing a deodorant / flame retardant fabric. The composition of obtaining a deodorizing effect on odors in general by using one or a mixture of one or more of zinc oxide, silica, zeolite, hydrazine compound and styrene-maleic anhydride hydrolyzate as the odorant. It is disclosed in Document 2. In these Patent Documents 1 and 2, in order to deal with various kinds of odor molecules, it is essential to use deodorant components and adsorbent substances according to the category of each malodor component evenly. As the number of components and adsorbents used in combination increases, the presence of these components interferes with each other, especially when a deodorizing component or adsorbing material that adsorbs a specific odor molecule is present first. There has been a glimpse of the problem that the effects of the adsorptive substances are hindered, and as a result, the deodorizing effect and the deodorizing effect on the daily life odor as intended cannot be sustained.

本発明の臭気吸着メッシュシートの空隙率は１０〜６５％、特に２０〜４５％が表面積を大きくし、しかも通気性を高くすることで、臭気成分の吸着効果を高めることができる。また、経方向及び緯方向１インチ当たり、または経方向とバイアス方向が、共に空孔数５〜３０個、特に８〜２０個を有するものが好ましい。空隙率が１０％未満の場合と、空隙率が６５％を超える場合には、得られるメッシュシートの表面積が小さくなり、通気性とガス交換性が不十分となり、減臭効果や消臭効果の発現が非効率的となることがある。同様に経緯とも、１インチ当たりの空孔数５個未満の場合と、空孔数３０個を超える場合には、得られるメッシュシートの表面積が小さくなり、通気性とガス交換性が不十分となり、減臭効果や消臭効果の発現が非効率的となることがある。空隙率はメッシュシートの単位面積領域に占めるコーテッドヤーン間空孔部の総和面積率であり、具体的には１インチ四方の面積領域のデジタル画像をコンピュータに取り込んで、コーテッドヤーン実体部と空孔部分の面積を計算する方法、またコーテッドヤーンの幅と、コーテッドヤーンの配置密度の設計から理論値として計算した値であってもよい。このようにコーテッドヤーン（１）及びコーテッドヤーン（２）を２：１〜１：２の本数比率で併用することによって、アンモニア、トリメチルアミンなどの塩基性悪臭に対する減臭効果が期待される二酸化珪素粒子を含有するコーテッドヤーン（１）と、硫化水素、メチルメルカプタン、酢酸、イソ吉草酸、ノネナールなどの酸性悪臭に対する減臭効果が期待される金属酸化物粒子を含有するコーテッドヤーン（２）とが併用され、各々のコーテッドヤーンが塩基性悪臭と酸性悪臭を選択的、かつ効率的に吸着する役割を担うようになるので、二酸化珪素粒子と金属酸化物粒子とが共存することで、塩基性悪臭と酸性悪臭との吸着効率を互いに阻害したりするような問題を回避できる。 The porosity of the odor adsorbing mesh sheet of the present invention is 10 to 65%, particularly 20 to 45%, increasing the surface area and increasing the air permeability, thereby enhancing the effect of adsorbing odor components. Further, it is preferable that the warp direction and the weft direction per inch, or both the warp direction and the bias direction have 5 to 30 holes, particularly 8 to 20 holes. When the porosity is less than 10% and when the porosity exceeds 65%, the surface area of the resulting mesh sheet is reduced, the air permeability and gas exchange are insufficient, and the deodorizing effect and deodorizing effect are reduced. Expression may be inefficient. Similarly, when the number of holes per inch is less than 5 and when the number of holes exceeds 30, the surface area of the resulting mesh sheet is reduced, resulting in insufficient air permeability and gas exchange. In some cases, the deodorizing effect and the deodorizing effect may be inefficient. The porosity is the total area ratio of the inter-coated yarn voids in the unit area of the mesh sheet. Specifically, the digital image of the area region of 1 inch square is taken into a computer, and the coated yarn actual part and the void are obtained. It may be a value calculated as a theoretical value from the method of calculating the area of the portion, or the design of the width of the coated yarn and the arrangement density of the coated yarn.

実施例１〜８のメッシュシートは、二酸化珪素及びゼオライトを質量比１：１とする混合粒子を１４．２〜２７．５質量％含む熱可塑性樹脂組成物層Ａで被覆したコーテッドヤーン（１）、及び（酸化亜鉛または酸化アルミニウム）及びゼオライトを質量比１：１〜１：２とする混合粒子を１４．２〜２７．５質量％含む熱可塑性樹脂組成物層Ｂで被覆したコーテッドヤーン（２）を１〜１の本数比率で併用して製織された製織交点を有するバスケット織メッシュシート、及び三軸バスケット織メッシュシートであり、コーテッドヤーン（１）とコーテッドヤーン（２）とに、各々二酸化珪素粒子及び金属酸化物（酸化亜鉛または酸化アルミニウム）を振り分け、熱可塑性樹脂組成物層内に同時にこれらが混在しないように設計したことによって、各々のコーテッドヤーンが塩基性悪臭と酸性悪臭を選択的、かつ効率的に吸着する役割を担い、二酸化珪素粒子と金属酸化物粒子とが共存することで、塩基性悪臭と酸性悪臭との吸着効率を互いに阻害したりするような障害を回避できること、また両者のコーテッドヤーン双方にゼオライト粒子を含有することでシンナーやトルエンなどの有機溶剤、ホルムアルデヒドなどの揮発性化学物質臭などに対して吸着性を有するので、臭気成分全般（ＶＯＣ含む）に対して長期間バランス良く濃度を減少させる減臭効果、及び経時的に人間の感知限界濃度に引き下げる消臭効果を有するメッシュシートが得られること、さらに減臭効果が飽和状態となっても、（熱）水洗、ヒーター加熱、及び天日干し、の単独、または併用の処理によって臭気吸着率を初期の５０％以上に容易に回復できることなどの特徴が確認された。 Coated yarns (1) coated with the thermoplastic resin composition layer A containing 14.2 to 27.5% by mass of mixed particles having a mass ratio of 1: 1 of silicon dioxide and zeolite. And a coated yarn (2) coated with a thermoplastic resin composition layer B containing 14.2 to 27.5% by mass of mixed particles having a mass ratio of 1: 1 to 1: 2 (zinc oxide or aluminum oxide) and zeolite ) And a triaxial basket weave mesh sheet woven with a 1 to 1 number ratio in combination, and each coated yarn (1) and coated yarn (2) is treated with carbon dioxide. This is because silicon particles and metal oxides (zinc oxide or aluminum oxide) are distributed and designed so that they do not coexist in the thermoplastic resin composition layer at the same time. Each coated yarn plays a role of selectively and efficiently adsorbing basic and acidic odors, and the coexistence of silicon dioxide particles and metal oxide particles makes it possible to eliminate basic and acidic odors. It is possible to avoid obstacles that interfere with each other's adsorption efficiency, and both coated yarns contain zeolite particles to adsorb organic solvents such as thinner and toluene, and volatile chemical odors such as formaldehyde. Therefore, it is possible to obtain a mesh sheet having a deodorizing effect that reduces the concentration in a well-balanced manner over a long period of time with respect to all odor components (including VOC), and a deodorizing effect that lowers to the human perception limit concentration over time, Furthermore, even if the deodorizing effect becomes saturated, the odor can be obtained by treatment with (hot) water washing, heater heating, and sun drying alone or in combination. Features such as can be easily restored to 50% or more initial adsorption rate was observed.

比較例１のメッシュシートは同一熱可塑性樹脂組成物層内に二酸化珪素粒子と金属酸化物（酸化亜鉛または酸化アルミニウム）が混在したことによって、アンモニアのような塩基性悪臭を先に吸着してしまうと、次いでイソ吉草酸のような酸性悪臭の吸着を試みても、実施例のような本来の減臭効果が得られず、次いで同様に硫化水素での吸着を試みても、実施例のような本来の減臭効果が得られず、最後にトルエンの吸着については実施例レベルの減臭効果を発現していたが、比較例１のメッシュシートでは生活臭全般に対する減臭効果や消臭効果が不十分であることが明らかであった。また比較例１のメッシュシートは回復処理で減臭効果が初期の５０％以上回復するものであったが、初期の減臭性能自体が悪いガスが２種類存在することで、その回復使用の価値を認めないものであった。また比較例２のメッシュシートは４種類の臭気成分ガスの吸着に対して、実施例１〜８のメッシュシートの減臭効果よりも劣っており、しかも吸着効果の回復性にも乏しいものであった。 The mesh sheet of Comparative Example 1 adsorbs a basic malodor such as ammonia first because silicon dioxide particles and metal oxide (zinc oxide or aluminum oxide) are mixed in the same thermoplastic resin composition layer. Then, even if an attempt is made to adsorb an acidic malodor such as isovaleric acid, the original deodorizing effect as in the example cannot be obtained. The original deodorizing effect could not be obtained, and finally, the adsorption level of toluene exhibited an example-level deodorizing effect. However, the mesh sheet of Comparative Example 1 has a deodorizing effect and a deodorizing effect on the general daily odor. Was clearly insufficient. Further, the mesh sheet of Comparative Example 1 recovered 50% or more of the initial deodorizing effect by the recovery treatment, but the presence of two kinds of gases having poor initial deodorizing performance itself is worth the recovery use. Was not allowed. In addition, the mesh sheet of Comparative Example 2 is inferior to the deodorizing effect of the mesh sheets of Examples 1 to 8 with respect to the adsorption of the four kinds of odor component gases, and also has poor recoverability of the adsorption effect. It was.
