Description
本発明は、衣料や、カーテン、カーペット、壁紙等のインテリア用品、衛生材料などに広く応用でき、消臭、抗菌および防汚機能を有するようにした繊維布帛に関する技術である。 The present invention relates to a textile fabric that can be widely applied to clothing, interior goods such as curtains, carpets, and wallpaper, and sanitary materials, and has a deodorizing, antibacterial, and antifouling function.
従来技術として、消臭、抗菌および防汚等の機能に関する技術は良く知られている。例えば、活性炭の優れた吸着作用を利用した消臭剤が知られているが、これらは悪臭成分を吸着し、周辺の臭気濃度を短期的に低下さす働きには優れているが、悪臭成分の量が減少するわけではなく、有効期間に限りのある消臭方法である。 As conventional techniques, techniques relating to functions such as deodorization, antibacterial action, and antifouling are well known. For example, deodorizers using the excellent adsorption action of activated carbon are known, but these adsorb bad odor components and are excellent in the action of lowering the odor concentration in the short term. The amount is not reduced, but it is a deodorizing method with a limited shelf life.
また、消臭スプレーを、直接臭気を発するものに吹きつけ消臭するものもあるが、この方法は、芳香剤の働きにより、一時的に臭いは消えるものの時間がたてば再び臭気が発生し、根本的な解決にはつながらない。 In addition, there is a deodorizing spray that blows directly on those that emit odor, but this method causes the odor to reappear after a while although the odor temporarily disappears due to the action of the fragrance. , It does not lead to a fundamental solution.
次ぎに、悪臭成分を分解して消臭する方法としては、フタロシアニンが良く知られているが、全ての悪臭に有効なものではなく、タバコ臭や、人体の汗の臭いであるイソ吉草酸等の悪臭に対しては有効な消臭方法とは言いがたいものである。 Next, phthalocyanine is well known as a method for decomposing and deodorizing malodorous components, but it is not effective for all bad odors, such as tobacco odor and isovaleric acid which is the smell of human sweat. It is difficult to say that it is an effective deodorizing method for the bad odors.
フタロシアニンの他では、悪臭成分を分解して消臭する方法として、酸化チタン光触媒が良く知られている。酸化チタン光触媒は、水中のハロゲン含有有機物を炭酸ガスと水に分解したり、たばこ臭や人体の汗の臭いであるイソ吉草酸等の悪臭を消臭したり、布に付着したたばこのヤニ等の着色物質を分解して防汚効果もあることが知られている。 In addition to phthalocyanine, a titanium oxide photocatalyst is well known as a method for decomposing and deodorizing malodorous components. Titanium oxide photocatalyst decomposes halogen-containing organic substances in water into carbon dioxide gas and water, deodorizes bad odors such as cigarette odor and isovaleric acid which is the smell of human sweat, cigarette spider adhering to cloth, etc. It is known that there is also an antifouling effect by decomposing the colored substances.
また、酸化チタン光触媒は、その強力な酸化力によって、大腸菌などを殺す機能もあることは確認されており、抗菌効果のあることが知られている。 Further, it has been confirmed that the titanium oxide photocatalyst has a function of killing Escherichia coli and the like by its strong oxidizing power, and is known to have an antibacterial effect.
しかしながら、光触媒はそのような有益な機能を有する反面、光触媒を直接繊維布帛にバインダー樹脂によって担持させると、光触媒の強い酸化分解力によって、バインダー樹脂や繊維布帛が有機質の炭化水素を含む樹脂であるため分解したり、着色したり、異臭が発生するなどの諸問題が生じていたため、使用が限定され、酸化に強いタイルやガラス等の無機の担持素材へ応用されることが多かった。 However, the photocatalyst has such a useful function, but when the photocatalyst is directly supported on the fiber cloth by the binder resin, the binder resin or the fiber cloth is a resin containing organic hydrocarbons due to the strong oxidative decomposition power of the photocatalyst. As a result, various problems such as decomposition, coloring, and off-flavor generation have occurred, so the use is limited, and it is often applied to inorganic support materials such as tiles and glass that are resistant to oxidation.
これを改善するため特許文献１においては、繊維布帛に酸化チタン光触媒をシリコーン架橋型樹脂で固定することにより、使用に際して繊維布帛に変色や劣化がなく、持続性のある優れた消臭、抗菌および防汚機能を有する繊維布帛の技術を開示している。 In order to improve this, in Patent Document 1, a titanium cloth photocatalyst is fixed to a fiber cloth with a silicone cross-linked resin, so that the fiber cloth is not discolored or deteriorated during use, and has excellent deodorizing, antibacterial and antibacterial properties. A technique of a fiber fabric having an antifouling function is disclosed.
また、特許文献２においても、繊維布帛の表面にフッ素樹脂からなる耐食性皮膜を形成し、この耐食性被膜の上に光触媒皮膜を形成することにより、繊維布帛に変色や劣化がない消臭性布帛の技術を開示している。 Also in Patent Document 2, a deodorant fabric having no discoloration or deterioration of the fiber fabric is formed by forming a corrosion-resistant coating made of a fluororesin on the surface of the fiber fabric and forming a photocatalytic coating on the corrosion-resistant coating. The technology is disclosed.
しかし、上記方法では、繊維布帛の風合いが硬くなり、また、光触媒の酸化作用から完全に繊維布帛を保護することが不可能で、繊維布帛やバインダー樹脂の変色や劣化を防ぐことに満足のできるものは出来ていない。本発明の課題は、上述の事情に鑑み、繊維布帛の柔らかな風合いを維持し、光触媒の酸化作用による変色や劣化を完全に防いだ消臭、抗菌および防汚機能を有する繊維布帛を提供することにある。 However, in the above method, the texture of the fiber fabric becomes hard, and it is impossible to completely protect the fiber fabric from the oxidation action of the photocatalyst, and it is satisfactory to prevent discoloration and deterioration of the fiber fabric and the binder resin. Things are not made. An object of the present invention is to provide a fiber fabric having a deodorizing, antibacterial, and antifouling function that maintains the soft texture of the fiber fabric and completely prevents discoloration and deterioration due to the oxidation action of the photocatalyst in view of the above-described circumstances. There is.
本発明は、繊維布帛の柔らかな風合いを維持し、変色や劣化を完全に防いだ消臭、抗菌および防汚機能を有する繊維布帛を提供すべく検討を行なった結果、アクリルシリコン系バインダー樹脂で、酸化チタン光触媒を繊維布帛に担持させることによって、柔らかな風合いのままで消臭、抗菌および防汚機能に優れた繊維布帛が得られることを見出し、本発明に至ったものである。 The present invention has been studied to provide a fiber fabric having a deodorizing, antibacterial and antifouling function that maintains the soft texture of the fiber fabric and completely prevents discoloration and deterioration. The present inventors have found that by supporting a titanium oxide photocatalyst on a fiber cloth, a fiber cloth excellent in deodorizing, antibacterial and antifouling functions can be obtained while maintaining a soft texture.
すなわち第１の発明は、繊維布帛に酸化チタン光触媒がアクリルシリコン系バインダー樹脂により固定されてなる、消臭、抗菌、および防汚機能を有する繊維布帛である。 That is, the first invention is a fiber fabric having a deodorizing, antibacterial, and antifouling function, wherein a titanium oxide photocatalyst is fixed to the fiber fabric with an acrylic silicon binder resin.
本発明は衣料用や、カーテン、カーペット、壁紙等のインテリア用品、衛生材料などに広く有用な繊維布帛として使用することができる。また、繊維布帛の繊維としては、ポリエステル、ポリアミド、アクリルなどの合成繊維、アセテート、レーヨンなどの半合成繊維、羊毛、絹、木綿、麻などの天然繊維などから選ばれる、1種または複数の繊維を使用することができる。 INDUSTRIAL APPLICABILITY The present invention can be used as a textile fabric that is widely useful for clothing, interior goods such as curtains, carpets, and wallpaper, and sanitary materials. In addition, as the fiber of the fiber fabric, one or more fibers selected from synthetic fibers such as polyester, polyamide and acrylic, semi-synthetic fibers such as acetate and rayon, natural fibers such as wool, silk, cotton and hemp Can be used.
本発明のメカニズムは十分解明されていないが、酸化チタン光触媒は、アクリルシリコン系バインダー樹脂のシリコン基とシラノール結合 で接合し、又アクリルシリコン系バインダー樹脂のアクリル基は、繊維布帛と強力に接合する。このよう、酸化チタン光触媒が繊維布帛に直接結合するのではなく、シリコン基と酸化チタン光触媒、アクリル基と繊維布帛がそれぞれ選択的に結合することから、光触媒の酸化作用から繊維布帛の変色や劣化を防ぐことができるものである。また、アクリル基を介して繊維布帛と酸化チタン光触媒とが間接的に接合することから、繊維の柔らかい風合いが守られるものである。 Although the mechanism of the present invention has not been fully elucidated, the titanium oxide photocatalyst is bonded to the silicon group of the acrylic silicon-based binder resin by a silanol bond, and the acrylic group of the acrylic silicon-based binder resin is strongly bonded to the fiber fabric. . As described above, the titanium oxide photocatalyst is not directly bonded to the fiber cloth, but the silicon group and the titanium oxide photocatalyst and the acrylic group and the fiber cloth are selectively bonded to each other. Can be prevented. Moreover, since the fiber fabric and the titanium oxide photocatalyst are indirectly bonded via an acrylic group, the soft texture of the fibers is protected.
また、酸化チタン光触媒をアクリルシリコン系バインダー樹脂のシリコン基を介して、繊維布帛と間接的に固定することにより、酸化チタン光触媒によって繊維やバインダー樹脂が侵されない状態を確保したうえで、従来消臭が困難であったタバコ臭、汗臭などを簡単に消臭することができ、また付着したタバコのヤニなどの着色物質を分解して、防汚効果も得ることができるものである。 In addition, by fixing the titanium oxide photocatalyst indirectly to the fiber fabric through the silicon group of the acrylic silicon binder resin, the titanium oxide photocatalyst ensures a state in which the fiber and the binder resin are not attacked, and the conventional deodorization is performed. It is possible to easily deodorize tobacco odors, sweat odors, etc., which have been difficult to remove, and to disassemble colored substances such as tobacco crabs, which can also provide an antifouling effect.
さらに、酸化チタン光触媒は、その酸化力により、黄色ブドウ球菌などに殺菌力があることは知られており、菌が人体代謝物などを分解する時に発生する悪臭を抑制し、抗菌効果も得ることができるものである。 Furthermore, titanium oxide photocatalysts are known to have bactericidal properties against Staphylococcus aureus due to their oxidative power, which suppresses malodors that occur when bacteria decompose human metabolites and the like, and also has an antibacterial effect It is something that can be done.
第２の発明は、前記酸化チタン光触媒の粒径が５ｎｍ〜２０μｍである請求項１記載の消臭、抗菌、および防汚機能を有する繊維布帛である。酸化チタン光触媒の粒径が２０μｍを越えると悪臭の分解速度が遅くなり好ましくない。また、５ｎｍを下回る粒径とすることは技術的に製造することは困難で、コスト的にも採算が合わず好ましくない。より好ましくは７ｎｍ〜５μｍがよい。 2nd invention is a fiber fabric which has a deodorizing, antibacterial, and antifouling function of Claim 1 whose particle size of the said titanium oxide photocatalyst is 5 nm-20 micrometers. When the particle size of the titanium oxide photocatalyst exceeds 20 μm, the malodor decomposition rate is slow, which is not preferable. Further, it is difficult to technically produce a particle size of less than 5 nm, which is not preferable because it is not profitable in terms of cost. More preferably, the thickness is 7 nm to 5 μm.
第３の発明は、前記酸化チタン光触媒の繊維布帛への付着量が、繊維布帛１００重量部に対し、０．５〜２５重量％である請求項１又は２記載の消臭、抗菌、および防汚機能を有する繊維布帛である。 According to a third aspect of the present invention, the amount of the titanium oxide photocatalyst attached to the fiber fabric is 0.5 to 25% by weight with respect to 100 parts by weight of the fiber fabric. It is a fiber fabric having a soiling function.
酸化チタン光触媒の繊維布帛への付着量が２５重量％を越えると風合いが硬くなり、また繊維布帛が白化して好ましくない。また、０．５重量％を下回ると悪臭の分解速度が遅く、消臭効果が弱くなり好ましくない。より好ましくは０．７〜１０重量％である。 If the amount of the titanium oxide photocatalyst attached to the fiber cloth exceeds 25% by weight, the texture becomes hard and the fiber cloth is whitened. On the other hand, if it is less than 0.5% by weight, the malodor decomposition rate is slow and the deodorizing effect becomes weak, which is not preferable. More preferably, it is 0.7 to 10% by weight.
本発明によれば、アクリルシリコン系バインダー樹脂のシリコン基とアクリル基が選択的に酸化チタン光触媒と繊維布帛に強く結合することから、酸化チタン光触媒の強い酸化作用の影響が回避され、使用に際して繊維布帛の変色や劣化がなく、かつ持続性のある優れた消臭、抗菌、および防汚機能を有する繊維布帛を得ることができる。本発明の繊維布帛は、衣料、カーテン、カーペット、壁紙等のインテリア用品、衛生材料などに広く有用な繊維布帛として用いられる。 According to the present invention, since the silicon group and the acrylic group of the acrylic silicon-based binder resin are selectively strongly bonded to the titanium oxide photocatalyst and the fiber fabric, the influence of the strong oxidizing action of the titanium oxide photocatalyst is avoided, and the fiber is used in use. There is no discoloration or deterioration of the fabric, and it is possible to obtain a fiber fabric having excellent deodorant, antibacterial, and antifouling functions that is durable. The fiber fabric of the present invention is used as a fiber fabric that is widely useful for interior goods such as clothing, curtains, carpets, wallpaper, and sanitary materials.
本発明の消臭、抗菌および防汚機能を有する繊維布帛について詳細に説明する。酸化チタン光触媒はアクリルシリコン系バインダー樹脂のシリコン基とシラノール結合で接合し、又アクリルシリコン系バインダー樹脂のアクリル基は繊維布帛とそれぞれ選択的に強力に接合する。 The fiber fabric having the deodorizing, antibacterial and antifouling functions of the present invention will be described in detail. The titanium oxide photocatalyst is bonded to the silicon group of the acrylic silicon-based binder resin by a silanol bond, and the acrylic group of the acrylic silicon-based binder resin is selectively and strongly bonded to the fiber fabric.
このように、選択的にシリコン基が酸化チタン光触媒とシラノール結合するため、アクリルシリコン系バインダー樹脂と酸化チタン光触媒との混合液をつくる時に、優先してシリコン基は酸化チタン光触媒と結合を完了している。その後繊維布帛に浸漬・塗布されることにより、アクリルシリコン系バインダー樹脂のアクリル基が繊維と直接接合することから、酸化チタン光触媒が繊維と直接接合するのを防ぎ、さらに柔軟性を保ちながら繊維と接合するものである。 In this way, since the silicon group selectively forms a silanol bond with the titanium oxide photocatalyst, the silicon group preferentially completes the bond with the titanium oxide photocatalyst when making a mixture of the acrylic silicon binder resin and the titanium oxide photocatalyst. ing. Thereafter, the acrylic group of the acrylic silicone binder resin is directly bonded to the fiber by being dipped and applied to the fiber fabric, so that the titanium oxide photocatalyst is prevented from directly bonding to the fiber, and the fiber is maintained while maintaining flexibility. It is what is joined.
アクリルシリコン系バインダー樹脂によって酸化チタン光触媒を繊維布帛に担持させる方法は、浸漬法とコーティング法を例示できる。アクリルシリコン系バインダー樹脂は水溶性であるので、容易に酸化チタン光触媒との混合液を得ることができる。 Examples of the method of supporting the titanium oxide photocatalyst on the fiber fabric with the acrylic silicon-based binder resin include an immersion method and a coating method. Since the acrylic silicon-based binder resin is water-soluble, a liquid mixture with the titanium oxide photocatalyst can be easily obtained.
浸漬法は、繊維布帛をアクリルシリコン系バインダー樹脂と酸化チタン光触媒の混合液に浸漬した後マングルで絞り、これを乾燥させることによって繊維布帛に酸化チタン光触媒を担持させるもので均一に担持することができる。 In the dipping method, the fiber fabric is immersed in a mixed solution of an acrylic silicon binder resin and a titanium oxide photocatalyst, then squeezed with mangle, and dried to support the titanium oxide photocatalyst on the fiber fabric. it can.
コーティング法は、繊維布帛にアクリルシリコン系バインダー樹脂と酸化チタン光触媒の混合液をコーティングした後乾燥させることによって繊維布帛に酸化チタン光触媒を担持させるもので、生産性を顕著に向上でき、担持量も精度高く制御できる。前記コーティング方法は、特に限定されるものではないが、例えばグラビアロール加工、スプレー加工、ロールコーター加工、ジェットプリント加工、転写プリント加工、スクリーンプリント加工等を例示することができる。 In the coating method, the fiber cloth is coated with a mixed liquid of an acrylic silicon binder resin and a titanium oxide photocatalyst and then dried to support the titanium oxide photocatalyst on the fiber cloth. Control with high accuracy. The coating method is not particularly limited, and examples thereof include gravure roll processing, spray processing, roll coater processing, jet print processing, transfer print processing, and screen print processing.
コーティング法は、アクリルシリコン系バインダー樹脂を繊維布帛上に皮膜状に層となって全面接着するよりも、網目状に接着させることが可能な加工方法として有用な加工である。これは、バインダー樹脂が層となって全面接着するのではなく、網目状に接着させることにより、繊維布帛を構成する糸が相対的に動きうることから、繊維布帛の柔軟性が確保されることと、繊維布帛に消臭、抗菌、防汚以外の機能性を付与する部分としての空間を残すことができ、難燃、撥水、撥油等の機能をさらに付与することができる。 The coating method is a processing useful as a processing method capable of adhering an acrylic silicon-based binder resin in a mesh form, rather than adhering the entire surface in a film form on a fiber fabric. This is because the flexibility of the fiber fabric is ensured because the yarns constituting the fiber fabric can move relatively by adhering the binder resin as a layer instead of adhering to the whole surface in a mesh form. In addition, it is possible to leave a space as a portion for imparting functionalities other than deodorizing, antibacterial, and antifouling to the fiber fabric, and further impart functions such as flame retardancy, water repellency, and oil repellency.
酸化チタン光触媒はアナターゼ型酸化チタン光触媒、ルチル型酸化チタン光触媒、ブルカイト型酸化チタン光触媒が好ましく、中でも、アナターゼ型酸化チタン光触媒が特に好適である。酸化チタン光触媒は、紫外線により励起されて水や酸素が・ＯＨや・Ｏ２ −となり、強い酸化作用で有機物を、水とニ酸化炭素に分解し、消臭するものである。また、酸化チタン光触媒の触媒活性を高めるため、白金、パラジウム、ロジウムなどの白金族金属を担持させたものや、銀、銅、亜鉛などの殺菌性のある金属を担持させたものを使用することもできる。 As the titanium oxide photocatalyst, an anatase-type titanium oxide photocatalyst, a rutile-type titanium oxide photocatalyst, and a brookite-type titanium oxide photocatalyst are preferable. Titanium oxide photocatalyst is excited by ultraviolet rays, water and oxygen OH or - O 2 -, and the organic matter with a strong oxidizing action, decomposes into water and carbon dioxide, is intended to deodorization. In addition, in order to increase the catalytic activity of the titanium oxide photocatalyst, use one that carries a platinum group metal such as platinum, palladium, or rhodium, or one that carries a sterilizable metal such as silver, copper, or zinc. You can also.
また、本発明においては、酸化チタン光触媒としてアパタイト被覆酸化チタン光触媒を用いることもできる。アパタイト被覆酸化チタン光触媒は、酸化チタン光触媒の表面がリン酸カルシウムアパタイトにより被覆された複合材料である。アパタイト被覆酸化チタン光触媒は、酸化チタン光触媒が直接繊維布帛やバインダー樹脂と接合するのを防ぎ、強い酸化作用によって繊維布帛やバインダー樹脂が侵されることから守るものである。 In the present invention, an apatite-coated titanium oxide photocatalyst can also be used as the titanium oxide photocatalyst. The apatite-coated titanium oxide photocatalyst is a composite material in which the surface of the titanium oxide photocatalyst is coated with calcium phosphate apatite. The apatite-coated titanium oxide photocatalyst prevents the titanium oxide photocatalyst from directly joining to the fiber cloth or the binder resin, and protects the fiber cloth or the binder resin from being attacked by a strong oxidizing action.
また、酸化チタンの一部にＮドープ等を行なった、可視光域で励起する可視光応答型酸化チタン光触媒も知られており、これらも本発明において使うことができる。例えばＮやＳで酸化チタンのＯの一部を置換したアニオンドープ型や、Ｔｉの一部を別の原子で置換したカチオンドープ型が挙げられる。 In addition, a visible light responsive titanium oxide photocatalyst that is excited in the visible light region in which a part of titanium oxide is doped with N or the like is also known, and these can also be used in the present invention. For example, an anion doped type in which a part of titanium oxide O is substituted with N or S, and a cation doped type in which a part of Ti is substituted with another atom.
酸化チタン光触媒の粒径は酸化作用の効果から小さいほど好ましく、また繊維径の１０分の１以下の粒径のものが、脱落のし易さの面から好ましく、２０μｍ以下が推奨される。 The particle size of the titanium oxide photocatalyst is preferably as small as possible from the effect of oxidation, and a particle size of 1/10 or less of the fiber diameter is preferable from the viewpoint of easy removal, and 20 μm or less is recommended.
本発明に使用されるアクリルシリコン系バインダー樹脂は、共栄社化学製Ｓ−６０ＮＦＥを使用した。 The acrylic silicon-based binder resin used in the present invention was S-60NFE manufactured by Kyoeisha Chemical.
シリコン基の末端が
また、アクリル基は繊維との密着性に富み、物理的に強く結合する。特に、有機繊維であるアクリル、ナイロン、ポリエステル等の繊維との結合力は非常に強く、アクリル基が優先的に繊維布帛に結合し、接着部の柔軟性が確保され、耐久性も十分なものとなる。 In addition, the acrylic group is rich in adhesiveness with the fiber and is physically strongly bonded. In particular, the bonding strength with organic fibers such as acrylic, nylon, and polyester is very strong, the acrylic group is preferentially bonded to the fiber fabric, and the flexibility of the bonded portion is ensured, and the durability is sufficient. It becomes.
酸化チタン光触媒とアクリルシリコン系バインダー樹脂の配合割合は特に限定しないが、酸化チタン光触媒の配合量が増えると、酸化チタン光触媒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、アクリルシリコン系バインダー樹脂配合量が増えると、酸化チタン光触媒とアクリルシリコン系バインダー樹脂と結合する割合が増加し、酸化チタン光触媒の表面を覆ってしまうようになり、消臭、抗菌、防汚の機能性が低下する。 The blending ratio of the titanium oxide photocatalyst and the acrylic silicon-based binder resin is not particularly limited. However, when the blending amount of the titanium oxide photocatalyst increases, the probability of binding to the fiber cloth of the titanium oxide photocatalyst increases, which causes the fiber cloth to deteriorate. In addition, when the amount of the acrylic silicon binder resin is increased, the proportion of the titanium oxide photocatalyst and the acrylic silicon binder resin combined increases, and the surface of the titanium oxide photocatalyst is covered. The functionality of is reduced.
酸化チタン光触媒が無駄なくその消臭能力を十分発揮するために、繊維布帛へ担持する工程を２工程に分けて加工することも可能である。まず、第１の工程において、繊維布帛へアクリルシリコン系バインダー樹脂のみを担持させる。次に第２の工程において、酸化チタン光触媒を第１の工程で得た繊維布帛上に塗布することによって、酸化チタン光触媒を無駄なく均一に塗布することができる。 In order for the titanium oxide photocatalyst to fully exhibit its deodorizing ability without waste, it is possible to process the process of supporting the fiber fabric in two processes. First, in the first step, only the acrylic silicon-based binder resin is supported on the fiber fabric. Next, in the second step, the titanium oxide photocatalyst is applied onto the fiber fabric obtained in the first step, so that the titanium oxide photocatalyst can be uniformly applied without waste.
酸化チタン光触媒の繊維布帛への付着量は、繊維布帛１００重量部に対し、０．５〜２５重量％であることが好ましい。酸化チタン光触媒の繊維布帛への付着量が２５重量％を越えると風合いが硬くなり、また、白化して好ましくない。また、０．５重量％を下回ると悪臭の分解速度が遅く、消臭効果が弱くなり好ましくない。さらに好ましくは、０．７〜１０重量％である。 The adhesion amount of the titanium oxide photocatalyst to the fiber fabric is preferably 0.5 to 25% by weight with respect to 100 parts by weight of the fiber fabric. If the amount of the titanium oxide photocatalyst attached to the fiber fabric exceeds 25% by weight, the texture becomes hard and undesirably whitens. On the other hand, if it is less than 0.5% by weight, the malodor decomposition rate is slow and the deodorizing effect becomes weak, which is not preferable. More preferably, it is 0.7 to 10% by weight.
