A method for producing a deodorant fabric having a deodorizing performance can be provided.

次に、この発明に係る消臭布帛の一実施形態について説明する。この実施形態の布帛は、特に限定されず、織物、編物のカーテン、椅子張り地や、不織布、タフテッドカーペット、モケットのような立毛布帛等を挙げられる。中でも、自然な対流のうちに出来るだけ多くの消臭剤と接する方が消臭効率は良く、通気性があり、厚みの有る布帛が好適である。布帛を形成する繊維についても特に限定されず、ポリエステル繊維、ポリアミド繊維、ポリプロピレン繊維、アクリル繊維、レ−ヨン繊維等の繊維からなるもの等を好適に使用でき、その他麻、綿、羊毛等の天然繊維からなるもの等も使用できる。   Next, an embodiment of the deodorizing fabric according to the present invention will be described. The fabric of this embodiment is not particularly limited, and examples thereof include woven fabrics, knitted curtains, chair upholstery fabrics, napped fabrics such as nonwoven fabrics, tufted carpets, and moquettes. Among them, it is preferable to contact with as many deodorizers as possible in natural convection because a deodorant efficiency is good, air permeability is good, and a thick fabric is suitable. The fibers forming the fabric are not particularly limited, and those made of fibers such as polyester fibers, polyamide fibers, polypropylene fibers, acrylic fibers, rayon fibers, etc. can be suitably used, and other natural materials such as hemp, cotton, wool, etc. Those made of fibers can also be used.

一般に布帛には、消臭性能以外に、難燃、防虫、防汚等の各種機能性を付与すべく加工が施されることが多く、その加工を加えることにより、消臭布帛表面のPH値が酸性側に振れたり、塩基性に振れたりして消臭効果の低下を招くことがある。消臭布帛表面のPH値が酸性側に振れた場合は、酸性ガスの悪臭除去率の低下がみられ、消臭布帛表面のPH値が塩基性に振れた場合は、塩基性ガスの悪臭除去率の低下となってしまう。本発明においては、消臭加工を施す前の布帛表面のPH値を6〜8に保つことが大切で、各種機能性を付与する加工によって布帛表面のPH値が酸性側に振れたり、塩基性に振れた場合には、りん酸塩やクエン酸等の水溶液に浸漬して中和処理する必要があり、布帛表面のPH値を6〜8に調整した後で消臭加工を施すことにより、酸性ガスや塩基性ガスに効果的に作用し、消臭効率のよい消臭布帛とすることができる。室内における空気中の悪臭ガスには様々のものがあるが、代表的塩基性悪臭としてはアンモニア、トリメチルアミン等の塩基性ガスを挙げられる。また、酸性悪臭としては硫化水素、メチルメルカプタン、酢酸等の酸性ガスの悪臭ガスを挙げることができる。   In general, fabrics are often processed to provide various functionalities such as flame retardancy, insect repellency, and antifouling in addition to deodorant performance. By adding such processing, the pH value of the surface of the deodorant fabric is increased. May move to the acidic side or to the basic side, leading to a decrease in the deodorizing effect. When the pH value on the surface of the deodorant fabric fluctuates to the acidic side, the rate of removal of bad odors from the acid gas is reduced. The rate will drop. In the present invention, it is important to maintain the PH value of the fabric surface before the deodorizing process at 6 to 8, and the PH value of the fabric surface may be shifted to the acidic side by processing to impart various functionalities. If it is shaken, it is necessary to neutralize it by immersing it in an aqueous solution such as phosphate or citric acid. After adjusting the pH value of the fabric surface to 6 to 8, deodorizing treatment is performed. A deodorizing fabric that acts effectively on acid gas and basic gas and has high deodorizing efficiency can be obtained. There are various types of malodorous gases in the air in the room, and typical basic malodors include basic gases such as ammonia and trimethylamine. Examples of the acidic malodor include acidic malodor gases such as hydrogen sulfide, methyl mercaptan, and acetic acid.

本発明において、消臭剤を構成するヒドラジン誘導体としては、例えば、ヒドラジン系化合物と長鎖の脂肪族系化合物とを反応させたもの、あるいはヒドラジン系化合物と芳香族系化合物とを反応させたもの等が挙げられる。中でも、ヒドラジン及びセミカルバジドからなる群より選ばれる1種または2種の化合物と、炭素数8〜16のモノカルボン酸、ジカルボン酸、芳香族モノカルボン酸、および芳香族ジカルボン酸からなる群より選ばれる1種または2種以上の化合物との反応生成物や、ヒドラジン及びセミカルバジドからなる群より選ばれる1種または2種の化合物と炭素数8〜16のモノグリシジル誘導体及びジグリシジル誘導体からなる群より選ばれる1種または2種以上の化合物との反応生成物が好適である。このようなヒドラジン誘導体を用いることにより優れた悪臭除去性能を確保することができる。前記反応生成物としては、具体的には、セバシン酸ジヒドラジド、ドデカンニ酸ジヒドラジド、イソフタル酸ジヒドラジド等を挙げられるが、特にこれら例示の化合物に限定されるものではない。なお、このようなヒドラジン誘導体の水に対する溶解度は25℃において5g/L以下であるのが望ましい。水に対する溶解度がこの範囲内であれば、洗濯等によって水と接触することがあっても、ヒドラジン誘導体がこの水に溶解して流出してしまうことが防止される。   In the present invention, the hydrazine derivative constituting the deodorant is, for example, a product obtained by reacting a hydrazine compound and a long-chain aliphatic compound, or a product obtained by reacting a hydrazine compound and an aromatic compound. Etc. Among them, one or two compounds selected from the group consisting of hydrazine and semicarbazide, and a group consisting of monocarboxylic acid having 8 to 16 carbon atoms, dicarboxylic acid, aromatic monocarboxylic acid, and aromatic dicarboxylic acid are selected. A reaction product with one or more compounds, or one or two compounds selected from the group consisting of hydrazine and semicarbazide, and a group consisting of monoglycidyl derivatives and diglycidyl derivatives having 8 to 16 carbon atoms. Reaction products with one or more compounds are preferred. By using such a hydrazine derivative, excellent malodor removal performance can be ensured. Specific examples of the reaction product include sebacic acid dihydrazide, dodecanoic acid dihydrazide, and isophthalic acid dihydrazide. However, the reaction product is not particularly limited to these exemplified compounds. The solubility of such a hydrazine derivative in water is desirably 5 g / L or less at 25 ° C. If the solubility in water is within this range, the hydrazine derivative is prevented from dissolving and flowing out even if it comes into contact with water by washing or the like.

また、本発明において、消臭剤を構成する多孔質無機物質は、多孔質故に表面積が大きく、悪臭の吸着能力の優れたものとなる。例えばこのような多孔質無機物質としては、前述の活性炭、ゼオライト等が挙げられる。中でも、酢酸、アンモニア等に対して優れた吸着能を有するゼオライトを用いるのが好ましい。また、ゼオライトは、白色であり繊維に担持させた場合に活性炭よりも布帛の色彩に影響が少なく良好である。   In the present invention, the porous inorganic substance constituting the deodorant has a large surface area because of its porosity, and has an excellent malodor adsorption ability. For example, as such a porous inorganic substance, the above-mentioned activated carbon, zeolite, etc. are mentioned. Among these, it is preferable to use a zeolite having an excellent adsorption ability for acetic acid, ammonia and the like. In addition, zeolite is white and has a smaller influence on the color of the fabric than activated carbon when it is supported on a fiber, which is favorable.

また、本発明において、消臭剤を構成する金属酸化物としては、例えばアルミナ、酸化チタン、酸化亜鉛、酸化鉄などの金属酸化物を挙げられるが、これら例示のものに特に限定されるものではない。このような多孔質無機物質や金属酸化物を併用することにより、ヒドラジン誘導体の作用と相俟って、自然対流によって消臭布帛と接する悪臭を効果的に消臭することができる。ヒドラジン誘導体と多孔質無機物質と金属酸化物の配合比率は特に限定しないが、酸化チタン等金属酸化物の配合量が増えると、金属酸化物の繊維布帛に結合する確率が増え、繊維布帛を劣化させる原因となる。また、ゼオライト等の多孔質無機物質の配合量が増えると、布帛が白化して好ましくない。バインダー樹脂配合量が増えると、多孔質無機物質や金属酸化物の表面をバインダー樹脂が表面を覆ってしまうようになり、消臭性能が低下することから、多孔質無機物質と金属酸化物とヒドラジン誘導体とバインダー樹脂の四者の配合バランスが大切である。   In the present invention, examples of the metal oxide constituting the deodorant include metal oxides such as alumina, titanium oxide, zinc oxide, and iron oxide, but are not particularly limited to those exemplified. Absent. By using such a porous inorganic substance or metal oxide in combination, it is possible to effectively deodorize bad odors coming into contact with the deodorizing fabric by natural convection in combination with the action of the hydrazine derivative. The mixing ratio of the hydrazine derivative, the porous inorganic substance, and the metal oxide is not particularly limited. However, when the amount of the metal oxide such as titanium oxide increases, the probability of binding to the metal oxide fiber fabric increases and the fiber fabric deteriorates. Cause it. Moreover, when the compounding quantity of porous inorganic substances, such as a zeolite, increases, a fabric will whiten and it is unpreferable. When the amount of the binder resin increases, the surface of the porous inorganic substance or metal oxide becomes covered with the binder resin, and the deodorizing performance is lowered. Therefore, the porous inorganic substance, metal oxide, and hydrazine are reduced. The balance between the combination of the derivative and the binder resin is important.

消臭剤としては、平均粒径が10μm以下である、ヒドラジン誘導体と多孔質無機物質と金属酸化物とからなる消臭剤が好ましい。平均粒径が10μm以下であるので、布帛に担持したとき、ざらつき感を受けることなく、風合も良好な消臭布帛を得ることができる。中でも、平均粒径は5μm以下にするのが好ましく、特に好ましくは3μm以下である。   As the deodorant, a deodorant composed of a hydrazine derivative, a porous inorganic substance, and a metal oxide having an average particle size of 10 μm or less is preferable. Since the average particle size is 10 μm or less, it is possible to obtain a deodorized fabric having a good texture without feeling rough when it is carried on the fabric. Among these, the average particle size is preferably 5 μm or less, and particularly preferably 3 μm or less.

前記消臭剤の塗布量は2〜15g/m(乾燥重量)とするのが好ましい。2g/m未満では十分な除去性能が得られなくなるので好ましくない。また、15g/mを超えても大きな消臭性能の向上はなく、徒にコストを増大することになり好ましくない。 The application amount of the deodorant is preferably 2 to 15 g / m 2 (dry weight). Less than 2 g / m 2 is not preferable because sufficient removal performance cannot be obtained. Moreover, even if it exceeds 15 g / m < 2 >, there is no big improvement in deodorization performance, and it will increase cost easily, and is not preferable.

前記消臭剤の塗布方法は、まず前記消臭剤とバインダ−樹脂を水に分散させ水分散液からなる処理液を調合する。この時、これらの消臭剤、バインダ−樹脂を可能な限り分散させることが好ましく、バインダ−樹脂については、水との間でエマルジョン状態を形成することがより好ましい。また、調合の際予め先に消臭剤を水に分散させておいてから、バインダ−樹脂を分散するのが、消臭剤とバインダ−樹脂をより均一に分散させるのに好ましい。   In the method of applying the deodorant, first, a treatment liquid composed of an aqueous dispersion is prepared by dispersing the deodorant and a binder resin in water. At this time, it is preferable to disperse these deodorants and binder resin as much as possible, and it is more preferable that the binder resin forms an emulsion state with water. In addition, it is preferable to disperse the deodorant in water before mixing and then disperse the binder resin in order to more uniformly disperse the deodorant and the binder resin.

前記バインダ−樹脂は、どのような樹脂でも使用することができる。例えば、自己架橋型アクリル樹脂、メタアクリル樹脂、ウレタン樹脂、シリコン樹脂、グリオキザ−ル樹脂、酢酸ビニル樹脂、塩化ビニリデン樹脂、ブタジエン樹脂、メラミン樹脂、エポキシ樹脂、アクリル−シリコン共重合体樹脂、エチレン−酢酸ビニル共重合体樹脂、イソブチレン無水マレイン酸共重合体樹脂、エチレン−スチレン−アクリレ−トメタアクリレ−ト共重合体樹脂などが挙げられる。これらの樹脂を2種類以上混合してバインダ−樹脂としてもよい。   As the binder resin, any resin can be used. For example, self-crosslinking acrylic resin, methacrylic resin, urethane resin, silicone resin, glyoxal resin, vinyl acetate resin, vinylidene chloride resin, butadiene resin, melamine resin, epoxy resin, acrylic-silicone copolymer resin, ethylene- Examples thereof include vinyl acetate copolymer resin, isobutylene maleic anhydride copolymer resin, ethylene-styrene-acrylate-methacrylate copolymer resin, and the like. Two or more of these resins may be mixed to form a binder resin.

また、前記消臭剤には、分散剤や、増粘剤などの各種添加剤を、各種特性向上のため配合してもよい。こうして得られる消臭剤をカ−ペットやカーテン等の布帛に塗布させる。この塗布する手段としては、特に限定されるものではないが、例えばスプレ−法、浸漬法、コ−ティング法、パディング法等が挙げられる。塗布する時期は、カ−ペットの場合、パイル糸、基布、バッキング層それぞれ単体の状態でもよいし、基布にパイル糸を殖設した表皮層の形態で処理液を塗布してもよいし、接着層を介して表皮層とバッキング層と接着一体化した形態で塗布してもよい。また、消臭剤を目止め層の処理液に混入し、スプレ−やロ−ラ−コ−ティングで塗布して消臭機能のある目止め層としてもよい。また、カーテンの場合は、縫製したあとスプレ−法等で塗布しても良いし、生地の状態で浸漬法、コ−ティング法、パディング法等で塗付し乾燥してもよい。   Moreover, you may mix | blend various additives, such as a dispersing agent and a thickener, with the said deodorizer for various characteristic improvement. The deodorant thus obtained is applied to a fabric such as a carpet or a curtain. The means for applying is not particularly limited, and examples thereof include a spray method, a dipping method, a coating method, and a padding method. In the case of carpet, the application time may be a single state of the pile yarn, the base fabric, and the backing layer, or the treatment solution may be applied in the form of a skin layer in which the pile yarn is laid on the base fabric. Alternatively, the surface layer and the backing layer may be bonded and integrated with each other through the adhesive layer. Moreover, it is good also as a sealing layer which has a deodorizing function by mixing a deodorizing agent in the process liquid of a sealing layer, and apply | coating with a spray or roller coating. In the case of a curtain, it may be applied by a spraying method after sewing, or may be applied and dried by a dipping method, a coating method, a padding method or the like in a fabric state.

上記のように、処理液を付与した後に乾燥させるが、乾燥手段としては、加熱処理する方法が乾燥効率から好ましい。加熱処理温度は、100〜180℃とするのが好ましい。この温度での加熱処理によって、消臭剤の固着性をより高め、悪臭除去性能の持続耐久性を一層向上させることができる。   As described above, the treatment liquid is applied and then dried. As a drying means, a heat treatment method is preferable from the viewpoint of drying efficiency. The heat treatment temperature is preferably 100 to 180 ° C. By the heat treatment at this temperature, it is possible to further improve the sticking property of the deodorant and further improve the durability of the malodor removal performance.
