The thermoplastic resin coating layer of the odor adsorbing mesh sheet of the present invention contains 5 to 30% by mass, preferably 8 to 20% by mass of mixed particles of silicon dioxide, metal oxide, and zeolite, and occupies the mixed particles. The mixing amount of zeolite is 10 to 40% by mass, preferably 18 to 36% by mass, and the mixing ratio of silicon dioxide and metal oxide is 5: 1 to 1: 1, preferably 5: 2 to 3: 2. And If the amount of zeolite mixed is less than 10% by mass, the deodorizing effect against VOC-type malodors such as toluene, formaldehyde, and acetaldehyde may be diluted. As the zeolite, any of natural and synthetic zeolites can be used, and those having an average particle diameter of 1 μm to 10 μm can be used. Zeolite has a three-dimensional framework structure such as A type, X type, LSX type, L type, Y type, beta type, ferrilite type, mordenite type, etc., and has the general formula M 2 / n 0 ·· Na 2 O · Al 2 O 3 · 2.5SiO 2 · xH 2 O (wherein x is an integer representing the number of water of crystallization, M is a cation, and n is the valence of the cation). The cation is an alkali metal (sodium ion, potassium ion, lithium ion), alkaline earth metal (calcium ion, magnesium ion), ammonium ion, or the like. Further, if the mixing ratio of the metal oxide is larger than that of silicon dioxide (for example, the mixing ratio of silicon dioxide and metal oxide is 1: 2), the deodorizing effect against basic malodors such as ammonia and trimethylamine may be diluted. If the mixing ratio of the metal oxide is lower than that of silicon dioxide (for example, the mixing ratio of silicon dioxide and metal oxide is 10: 1), such as hydrogen sulfide, methyl mercaptan, acetic acid, isovaleric acid, nonenal, etc. Deodorizing effect against acidic malodor may be diluted. Silicon dioxide is a spherical silica by synthetic amorphous silica (wet method or dry method), or amorphous silica, silica gel particles, mesoporous silica having mesopores with a pore size of 2 to 50 nm on the surface, and the average particle size is 0.1 μm to 5 μm.

Furthermore , one or more selected from photocatalytically active zinc oxide, photocatalytically active titanium oxide, zinc oxide, titanium oxide, magnesium oxide, iron oxide, and copper oxide and having an average particle size of 0.1 μm to 5 μm can be used in combination.
また熱可塑性樹脂被覆層には必要に応じて、活性炭、添着活性炭、白竹炭、活性白土、ベントナイト、セピオライト、アルミノ珪酸金属塩、珪酸銅、シラス、シリカ−マグネシア、モレキュラーシーブ、電気石（トルマリン鉱石）、金属フタロシアニン錯体、金属フタロシアニン錯体テトラカルボン酸、（これらの錯体形成金属として、銅、鉄、コバルト、マンガンなど）などを０．１〜５質量％程度併用していてもよく、さらにヒドラジン化合物、スチレン−マレイン酸加水分解物、シクロデキストリン、ポリフェノール類、テルペノイド類、フラボノイド類などを補助的に０．１〜３質量％程度併用してもよい。 As necessary, the thermoplastic resin coating layer may be activated carbon, impregnated activated carbon, shiratake charcoal, activated clay, bentonite, sepiolite, aluminosilicate metal salt, copper silicate, shirasu, silica-magnesia, molecular sieve, tourmaline (tourmaline ore). ), A metal phthalocyanine complex, a metal phthalocyanine complex tetracarboxylic acid, (as these complex-forming metals, copper, iron, cobalt, manganese, etc.) may be used in an amount of about 0.1 to 5% by mass, and further a hydrazine compound Further, styrene-maleic acid hydrolyzate, cyclodextrin, polyphenols, terpenoids, flavonoids and the like may be used in an auxiliary manner in an amount of about 0.1 to 3% by mass.
また熱可塑性樹脂被覆層には、粒径が０．０３ｍｍ〜０．８ｍｍ気泡痕を０〜２５体積％、特に５〜１５体積％程度の比率で含み、メッシュシートの内部にも表面積を有する。このような内部表面積を設けることで臭気分子との接触面積を増し、通気性とガス交換性を促す効果によって減臭（消臭）効果を著しく向上させる。これらの気泡痕は全て連続気泡化することでガス交換性及び通気性に優れた構造、または部分的に連続気泡化したガス交換通気性の構成とするものである。これらの気泡痕は液状粘性体の熱可塑性樹脂組成物の機械攪拌による強制的な気泡巻込ムースの塗工と熱処理による気泡痕形成、液状粘性体の熱可塑性樹脂組成物（アルコール、トルエン、メチルエチルケトンなどの有機溶剤含有）の塗工と熱処理蒸散による揮発痕形成、公知の化学発泡剤（アゾジカルボアミド、オキシビスベンゼンスルフォニルヒドラジド、ベンゼンスルフォニルヒドラジド、ｐ−トルエンスルフォニルヒドラジド、ジアゾアミノベンゼン、アゾビスイソブチロニトリルなど）を含有する熱可塑性樹脂組成物層を熱処理して化学発泡剤を強制的に熱分解させることで揮発性ガスを生成させることによる気泡痕形成、砂糖粒や塩粒などの水溶性粒子を含有する熱可塑性樹脂組成物層の水洗処理による砂糖粒や塩粒の溶出による空洞痕形成など、何れの方法によって形成されたものであってもよい。 Further, the thermoplastic resin coating layer contains 0.03 mm to 0.8 mm bubble marks with a ratio of 0 to 25% by volume, particularly about 5 to 15% by volume, and also has a surface area inside the mesh sheet. By providing such an internal surface area, the contact area with odor molecules is increased, and the deodorizing (deodorizing) effect is remarkably improved by the effect of promoting air permeability and gas exchange. All of these bubble traces are formed into an open cell structure so as to have a structure excellent in gas exchange property and air permeability, or a gas exchange air permeability structure partially formed into open cells. These bubble marks are forcibly entrained bubble mousse by mechanical stirring of thermoplastic resin composition of liquid viscous material and formation of bubble marks by heat treatment, thermoplastic resin composition of liquid viscous material (alcohol, toluene, methyl ethyl ketone) Volatile trace formation by application of organic solvent such as volatile vaporization by heat evaporation, known chemical blowing agents (azodicarboxamide, oxybisbenzenesulfonyl hydrazide, benzenesulfonyl hydrazide, p-toluenesulfonyl hydrazide, diazoaminobenzene, azobis Such as isobutyronitrile, etc.) by forming a volatile gas by forcing thermal decomposition of the chemical foaming agent by heat-treating the thermoplastic resin composition layer containing isobutyronitrile, etc. By elution of sugar particles and salt particles by water washing treatment of thermoplastic resin composition layer containing water-soluble particles Like cavity scar formation, or it may be formed by any method.
粗目織物の全表面に熱可塑性樹脂被覆層を形成するには、基布とする粗目織物に対して液状の熱可塑性樹脂組成物によるディッピングやコーティングによる含浸被覆によって達成される。液状の熱可塑性樹脂としては、エマルジョン樹脂、ディスパージョン樹脂などの水分散形態、熱可塑性樹脂を有機溶媒中に可溶化した塗料形態、及び塩化ビニル樹脂ペーストゾルなどである。粗目織物の全表面を被覆する熱可塑性樹脂被覆層とで構成された多数の空孔を有する可撓性複合体は、空隙率１０〜６５％、特に２０〜４５％、かつ経緯１インチ当たり、共に空孔数５〜３０個、特に８〜２０個を有するものが好ましい。すなわち１インチ平方面積当たり、共に空孔数２５〜９００個、特に６４〜４００個を有するものが好ましい。また粗目織物を被覆する樹脂層の厚さは０．０３ｍｍ〜０．６ｍｍ、特に０．０５ｍｍ〜０．３ｍｍが好ましい。空隙率は可撓性複合体（メッシュシート）の単位面積領域に占める糸条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、糸条実体部と空孔部分の面積を計算する方法、また糸条の幅と、糸条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。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。 The formation of the thermoplastic resin coating layer on the entire surface of the coarse woven fabric can be achieved by dipping or coating with a liquid thermoplastic resin composition on the coarse woven fabric as the base fabric. Examples of the liquid thermoplastic resin include an aqueous dispersion form such as an emulsion resin and a dispersion resin, a paint form in which the thermoplastic resin is solubilized in an organic solvent, and a vinyl chloride resin paste sol. A flexible composite having a large number of pores composed of a thermoplastic resin coating layer covering the entire surface of the coarse woven fabric has a porosity of 10 to 65%, particularly 20 to 45%, and per inch of background. Those having both 5 to 30 holes, particularly 8 to 20 are preferred. That is, those having 25 to 900 holes, particularly 64 to 400 holes per inch square area are preferred. The thickness of the resin layer covering the coarse fabric is preferably 0.03 mm to 0.6 mm, particularly preferably 0.05 mm to 0.3 mm. The porosity is the total area ratio of the interstices voids in the unit area of the flexible composite (mesh sheet). Specifically, a digital image of an area area of 1 inch square is taken into a computer, It may be a value calculated as a theoretical value from the method of calculating the area of the yarn entity portion and the hole portion, or the design of the yarn width and the yarn arrangement density. 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.
本発明の臭気吸着メッシュシートにおいて、粗目織物と熱可塑性樹脂被覆層の中間には、粗目織物に対する含浸部を含む熱可塑性樹脂アンカー層を含んでいてもよい。この場合、意図的に熱可塑性樹脂アンカー層には混合粒子（二酸化珪素と金属酸化物、及びゼオライト）を含まないものとする。これによって減臭効果及び消臭効果に寄与する二酸化珪素と金属酸化物、及びゼオライトとによる混合粒子の配置をメッシュシートの最外層となる熱可塑性樹脂被覆層のみとすることで、少ない混合粒子の使用量でも同等の減臭効果及び消臭効果を得ることができる。特に熱可塑性樹脂被覆層を、可塑剤にシクロヘキサンジカルボン酸ジアルキルエステルを使用した軟質塩化ビニル樹脂組成物で構成した場合には、熱可塑性樹脂アンカー層も同様の可塑剤設計とすることが好ましい。内分泌攪乱化学物質（環境ホルモン）の疑いのあるフタル酸エステル系可塑剤を使用しないことで、特に乳幼児の経口摂取や経気摂取、母体から胎児への間接摂取によるホルモン作用異常のリスクを回避することを可能とする。熱可塑性樹脂アンカー層の形成は段落〔００２３〕と同様にして形成できる。 In the odor adsorbing mesh sheet of the present invention, a thermoplastic resin anchor layer including an impregnation portion for the coarse fabric may be included between the coarse fabric and the thermoplastic resin coating layer. In this case, the thermoplastic resin anchor layer intentionally does not contain mixed particles (silicon dioxide, metal oxide, and zeolite). By arranging only the thermoplastic resin coating layer that is the outermost layer of the mesh sheet, the arrangement of the mixed particles of silicon dioxide, metal oxide, and zeolite that contribute to the deodorizing effect and deodorizing effect is reduced. The same deodorizing effect and deodorizing effect can be obtained even with the amount used. In particular, when the thermoplastic resin coating layer is composed of a soft vinyl chloride resin composition using cyclohexanedicarboxylic acid dialkyl ester as a plasticizer, it is preferable that the thermoplastic resin anchor layer has a similar plasticizer design. By avoiding the use of phthalate plasticizers that are suspected of endocrine disrupting chemicals (environmental hormones), avoid the risk of abnormal hormonal effects due to oral intake, ingestion, and indirect intake from the mother to the fetus, especially in infants. Make it possible. The thermoplastic resin anchor layer can be formed in the same manner as in paragraph [0023].
