本考案は化学工場や加工工場あるいは養鶏、畜産、農薬散布等悪臭環境下の作 業者用として好適な消臭性の簡易マスクに関するものである。 The present invention relates to a deodorant simple mask suitable for a chemical factory, a processing factory, or an operator in a bad odor environment such as chicken farming, livestock farming, and pesticide spraying.
【0002】[0002]
従来、上記のような悪臭環境下に作業する人々のための消臭性のマスクの代表 例として、実開昭59−71654号公報、実開昭62−30856号公報およ び実開昭63−93951号公報が挙げられる。 Conventionally, as typical examples of deodorant masks for people who work in the above-mentioned odor environment, Japanese Utility Model Laid-Open No. 59-71654, Japanese Utility Model Laid-Open No. 62-30856 and Japanese Utility Model Laid-Open No. 63 are used. No. 93951 is cited.
【0003】 実開昭59−71654号公報記載のマスクは、マスク本体がポリウレタンホ ームシートで形成され、該マスク本体の両耳掛孔の中間部内面に布状またはペー パー状の活性炭繊維を不織布で包被してなる消臭シートが互換可能に取り付けら れて形成されている。In the mask described in Japanese Utility Model Laid-Open No. 59-71654, the mask body is formed of a polyurethane foam sheet, and a cloth-shaped or paper-shaped activated carbon fiber is non-woven fabric on the inner surface of the middle portion of the ear holes of the mask body. The deodorant sheet is covered with and is compatiblely attached.
【0004】 実開昭62−30856号公報記載のマスクは、マスク本体にフタロシアニン 化合物を含む繊維からなる呼気と吸気の通気用フィルターがもうけられてなり、 また実開昭63−93951号公報記載のマスクは、熱接着性複合繊維の融着に よって補強された活性炭素繊維不織布の両面に合成繊維不織布が積層され、半球 状に成形されてマスク本体が構成されている。The mask disclosed in Japanese Utility Model Laid-Open No. 62-30856 is provided with a filter for ventilation of exhalation and inhalation, which is made of a fiber containing a phthalocyanine compound, in the body of the mask, and also disclosed in Japanese Utility Model Laid-Open No. 63-93951. The mask body is constructed by forming synthetic fiber non-woven fabrics on both sides of activated carbon fiber non-woven fabrics reinforced by fusion bonding of heat-adhesive composite fibers, and forming them into a hemispherical shape.
【0005】[0005]
しかしながら、消臭用として活性炭素繊維を内装してなるマスクは、マスクの 折り曲げや反復屈折を受けると活性炭素繊維が折れて一部が微粉末化し、繊維間 を通り体内に吸入される恐れがあり、また活性炭素特有の黒色を隠蔽するにはマ スク本体の厚さをかなり大きくしなければならない。 However, in a mask containing activated carbon fibers for deodorization, when the mask is bent or repeatedly refracted, the activated carbon fibers are broken and a part thereof becomes fine powder, which may be inhaled into the body through the spaces between the fibers. Yes, and in order to hide the black color peculiar to activated carbon, the thickness of the mask body must be increased considerably.
【0006】 かかる不都合は上記実開昭62−30856号公報に記載されているフタロシ アニン化合物を含む消臭性の繊維を用いることにより改善することができるが、 この消臭性繊維でもって繊維間が結合された形態安定性のよいマスク本体を形成 することが困難であることから、専ら取り替え可能なフィルター用に適用されて いるのが実情である。Such inconvenience can be solved by using the deodorant fiber containing the phthalocyanine compound described in Japanese Utility Model Laid-Open No. 62-30856, but with this deodorant fiber Since it is difficult to form a mask body with good morphological stability in which the two are combined, it is actually applied exclusively to replaceable filters.
【0007】 また実開昭63−93951号公報記載の活性炭素繊維不織布に代えて上記実 開昭62−30856号公報記載の消臭性繊維を適用し、熱接着性繊維と併用し て不織布となし、この不織布を加熱加圧してマスクを形成すれば上記した不都合 は改善することができるが、このようにして得られた不織布マスクは、吸気抵抗 と粉塵捕集効率とのバランスが悪く、粉塵捕集効率をよくするべく緻密化すると 吸気抵抗が増大してマスク着用時の呼吸が困難化し、呼吸性をよくするべく粗密 化すると粉塵捕集効率が悪くなるという不都合が生じる。Further, instead of the activated carbon fiber non-woven fabric described in Japanese Utility Model Laid-Open No. 63-93951, the deodorant fiber described in Japanese Utility Model Laid-Open No. 62-30856 is applied, and a non-woven fabric is used in combination with the heat-adhesive fiber. None, if the non-woven fabric is heated and pressed to form a mask, the above-mentioned inconveniences can be solved, but the non-woven fabric mask obtained in this way has a poor balance between the intake resistance and the dust collection efficiency, so If it is made dense to improve the collection efficiency, inhalation resistance increases and it becomes difficult to breathe when wearing a mask, and if it is made dense to improve the breathability, the dust collection efficiency deteriorates.
【0008】 本考案は、繊維密度が小さくマスクとしての望ましい吸気抵抗を保持し、消臭 剤の脱落がなく、そのうえ消臭性と粉塵捕集効率の優れた簡易マスクを提供する ことを目的としているものである。An object of the present invention is to provide a simple mask which has a small fiber density, maintains a desired intake resistance as a mask, does not drop off a deodorant, and is excellent in deodorant property and dust collection efficiency. There is something.

本考案は、消臭性繊維と高融点極細繊維および低融点極細繊維とが混合された 不織布となしのち、熱風加工を行って低融点の極細繊維を溶融して繊維間接着を し、しかるのちマスク本体を形成することによって上記目的を達成したものであ る。 The present invention comprises a non-woven fabric in which deodorant fibers are mixed with high melting point ultrafine fibers and low melting point ultrafine fibers, and then hot air processing is performed to melt the low melting point ultrafine fibers to bond them to each other. The above object is achieved by forming the mask body.
【0010】 即ち本考案の消臭性簡易マスクは、マスク本体を形成している不織布が、酸化 還元能を有する金属錯体を1重量%以上担持させた繊維および/または金属イオ ンを0.1重量%以上担持させた繊維が30〜50重量%と、0.5デニール以 下の高融点極細繊維と低融点極細繊維が70〜50重量%とで構成され、マスク 本体は上記低融点極細繊維の溶融によって繊維間接着されて椀状の成形形状が保 持され、その不織布は、目付けが100〜200g/m2 、繊維密度が0.12 〜0.25g/cm3 であり、吸気抵抗が2.0〜3.0mmH2 O、2μm粉 塵の捕集効率が98%以上であって、マスク本体の両端に耳かけ紐が装着されて なることを特徴としているものである。That is, in the deodorant simple mask of the present invention, the non-woven fabric forming the mask body contains 0.1% by weight of fibers and / or metal ions carrying 1% by weight or more of a metal complex having an oxidation-reduction ability. The weight of the fiber is 30 to 50% by weight, and the melting point of the ultrafine fiber having a melting point of 0.5 denier or less and the ultrafine fiber of low melting point is 70 to 50% by weight. The fibers are adhered to each other by the fusion of the fibers to maintain a bowl-shaped molded shape, and the nonwoven fabric has a basis weight of 100 to 200 g / m 2 , a fiber density of 0.12 to 0.25 g / cm 3 , and an intake resistance of The collection efficiency of 2.0 to 3.0 mmH 2 O, 2 μm dust is 98% or more, and the mask main body is equipped with ear straps at both ends.
【0011】 本考案に用いる消臭性繊維は、例えば木綿、麻、レーヨンなどのセルロース系 繊維、羊毛、絹などの蛋白質繊維やポリアミド系繊維、ポリアクリル系繊維等の 合成繊維に鉄フタロシアニン・ポリカルボン酸またはコバルトフタロシアニン・ ポリカルボン酸の酸化還元能を有する金属錯体を1重量%以上、好ましくは1〜 5重量%担持させた繊維、銅、コバルト、鉄等の金属イオンを0.1重量%以上 、好ましくは1〜5重量%担持させた繊維であって、これらを単独あるいは併用 することによってマスクに消臭能を付与している。The deodorant fibers used in the present invention include, for example, cellulosic fibers such as cotton, hemp, and rayon, protein fibers such as wool and silk, polyamide fibers, synthetic fibers such as polyacryl fibers, and iron phthalocyanine poly. 0.1% by weight of fibers, metal ions such as copper, cobalt, iron, etc. carrying 1% by weight or more, preferably 1 to 5% by weight, of a metal complex having redox ability of carboxylic acid or cobalt phthalocyanine / polycarboxylic acid. As described above, the fibers are preferably loaded in an amount of 1 to 5% by weight, and the deodorizing ability is imparted to the mask by using these fibers alone or in combination.
【0012】 酸化還元能を有する金属錯体としては、金属ポルフィリン、金属ポルフィラジ ンおよびこれらの誘導体並びに高分子金属錯体が用いられる。金属ポルフィリン およびその誘導体は「化1」に示す構造式で表され、また金属ポルフィラジンお よびその誘導体は「化2」に示す構造式で表される。「化1」「化2」において Mは、Fe、Co、Mn、Ti、V、Ni、Cu、Zn、Mo、W等の金属のイ オンが挙げられる。これら金属イオンのうち消臭効果の点からは鉄、コバルトが 好ましい。「化1」、「化2」においてXは、水素または置換基を示す。置換基 としては、アルキル基、置換アルキル基(例えばクロロメチル基)、ハロゲン基 、ニトロ基、アミノ基、アゾ基、チオシアネート基、カルボキシル基、カルボニ ルクロリド基、カルボキシルアミド基、ニトリル基、水酸基、アルコキシル基、 フェノキシル基、スルホン酸基、スルホニルクロリド基、スルホンアミド基、チ オール基、アルキルケイ素基、ビニル基等のほか、カルボキシル基やスルホン酸 基のアルカリ塩などが挙げられる。これらは、単独または2種以上用いられる。 なかでも、好ましくはカルボキシル基やスルホン酸基またはこれらのアルカリ塩 類、アミノ基、ハロゲン基、水酸基なとが用いられる。As the metal complex having redox ability, metal porphyrins, metal porphyrazines and their derivatives, and polymer metal complexes are used. The metalloporphyrin and its derivative are represented by the structural formula shown in "Chemical formula 1", and the metalloporphyrazine and its derivative are represented by the structural formula shown in "Chemical formula 2". In “Chemical Formula 1” and “Chemical Formula 2”, M is an ion of a metal such as Fe, Co, Mn, Ti, V, Ni, Cu, Zn, Mo and W. Of these metal ions, iron and cobalt are preferable from the viewpoint of deodorizing effect. In "Chemical formula 1" and "Chemical formula 2", X represents hydrogen or a substituent. Examples of the substituent include an alkyl group, a substituted alkyl group (eg, chloromethyl group), a halogen group, a nitro group, an amino group, an azo group, a thiocyanate group, a carboxyl group, a carbonyl chloride group, a carboxylamide group, a nitrile group, a hydroxyl group, an alkoxyl group.

These are used alone or in combination of two or more. Of these, a carboxyl group, a sulfonic acid group, or an alkali salt thereof, an amino group, a halogen group, a hydroxyl group or the like is preferably used.

【0015】 金属イオンとしては、遷移金属であればよいが、なかでも銅、コバルト、鉄が 好ましい。担持量が金属錯体において1重量%未満、金属イオンにおいて0.1 重量%未満であると消臭活性が得られず、また消臭活性の持続性にも劣る。また マスク本体を構成する不織布中の上記消臭性繊維の占める割合が、30重量%未 満であると消臭活性が得られにくく、消臭活性の持続性も不十分となる。The metal ion may be a transition metal, but among them, copper, cobalt and iron are preferable. When the supported amount is less than 1% by weight in the metal complex and less than 0.1% by weight in the metal ion, the deodorant activity cannot be obtained, and the deodorant activity is inferior in sustainability. If the proportion of the above deodorant fibers in the nonwoven fabric constituting the mask body is less than 30% by weight, deodorant activity is difficult to obtain, and the sustainability of deodorant activity becomes insufficient.
【0016】 上記した消臭性繊維と交絡され、成形時に繊維間結合するための熱接着性繊維 としては、高融点成分と低融点成分とからなる分割型複合繊維、例えば高融点成 分がポリプロピレン、低融点成分がポリエチレンからなり、両成分を交互に放射 状に配してなる分割型複合繊維が好ましく適用することができる。そしてかかる 分割型複合繊維を50重量%以上混合し、分割処理して0.5デニール以下の極 細繊維となし、マスクを形成するとよい。この分割型複合繊維の混合量が50重 量%より少ないと繊維間接着が弱く、成形形状の保持が難しくなり、消臭性の維 持を考慮した場合その混合量は50〜70重量%が適切である。As the heat-adhesive fiber which is entangled with the above-mentioned deodorant fiber and bonded between fibers at the time of molding, a splittable conjugate fiber composed of a high melting point component and a low melting point component, for example, a high melting point component is polypropylene A splittable conjugate fiber in which the low melting point component is made of polyethylene and both components are alternately arranged radially can be preferably applied. It is advisable to mix 50% by weight or more of the splittable conjugate fiber and split it into fine fibers of 0.5 denier or less to form a mask. If the mixing amount of the splittable conjugate fiber is less than 50% by weight, the inter-fiber adhesion is weak and it becomes difficult to maintain the molded shape. Considering the maintenance of deodorant property, the mixing amount is 50 to 70% by weight. Appropriate.
【0017】 上記のように0.5デニール以下の高融点極細繊維と低融点極細繊維を50重 量%以上含有してその低融点成分の溶融にによって形成された不織布は、強く加 圧して緻密化して繊維間空隙を小さくしなくても微細な繊維間空隙を確保するこ とができ、繊維密度および吸気抵抗が小さいにも拘らず粉塵捕集効率を向上させ ることができる。As described above, a nonwoven fabric formed by melting 50% by weight or more of high-melting point ultrafine fibers having a denier of 0.5 and low melting point ultrafine fibers and melting the low-melting component is dense It is possible to secure fine inter-fiber voids without making the inter-fiber voids smaller, and it is possible to improve the dust collection efficiency despite the low fiber density and intake resistance.
【0018】[0018]
マスク本体の不織布内の消臭性繊維は、消臭物質が脱落することなく着用者の 呼吸により吸入される臭気を消去して悪臭感をなくし、極細繊維は繊維密度を高 めることなく適度な吸気抵抗を保ちながらマスク本体の不織布に高い粉塵捕集効 率を維持させる。 The deodorant fiber in the non-woven fabric of the mask body eliminates the odor inhaled by the wearer's breath without removing the deodorant substance and eliminates the bad odor, and the ultrafine fiber is moderate without increasing the fiber density. The non-woven fabric of the mask body maintains a high dust collection efficiency while maintaining high intake resistance.

The splittable conjugate fiber (6) is divided into a high melting point ultrafine fiber component (4) and a low melting point ultrafine fiber component (5) each having a denier of 0.19, and then dried and heated to produce a low melting point ultrafine fiber component (5). The fibers were adhered to each other by the fusion of the above to obtain a nonwoven fabric having a basis weight of about 160 g / m 2 , an apparent thickness of about 0.8 mm, and a fiber density of 0.20 g / cm 3 .
【0029】 しかるのちこの不織布を用いて「実施例1」と同様にの熱プレス機で椀状に成 形しながら低融点成分極細繊維成分(5)を溶融し、不織布の繊維間を結合して マスク本体(1)となし、耳かけ紐(2)を装着して図1のようなマスク(3) となした。このマスクの吸気抵抗は2.8mmH2 O、2μm粉塵の捕集効率が 99%以上であり、実施例1と同等の消臭効果を有していた。Thereafter, using this non-woven fabric, the low melting point component ultrafine fiber component (5) was melted while forming it into a bowl shape in the same heat pressing machine as in “Example 1” to bond the fibers of the non-woven fabric. The mask body (1) was removed, and the ear hook string (2) was attached to form a mask (3) as shown in FIG. The mask had an intake resistance of 2.8 mmH 2 O and a collection efficiency of 2 μm dust of 99% or more, and had the same deodorizing effect as in Example 1.

本考案の消臭簡易マスク(3)は、マスク本体(1)を形成している不織布が 、酸化還元能を有する金属錯体を1重量%以上担持させた繊維および/または金 属イオンを0.1重量%以上担持させた繊維が30〜50重量%と、0.5デニ ール以下の高融点成分極細繊維と低融点極細繊維が70〜50重量%とで構成さ れ、マスク本体は上記低融点極細繊維の溶融によって繊維間接着されて椀状の成 形形状が保持されているから、長期間に亙って消臭性能を有し、消臭繊維の折損 がなく安心して使用できる。そのうえマスク本体を構成している不織布は、目付 けが100〜200g/m2 、繊維密度が0.12〜0.25g/cm3 であり 、吸気抵抗が2.0〜3.0mmH2 Oという適度な通気性を有しているにも拘 らず2μm粉塵の捕集効率が98%以上であって、消臭効果とともに微細な塵埃 の通過を阻止し、極めて衛生的である。In the deodorant simple mask (3) of the present invention, the non-woven fabric forming the mask body (1) contains fibers and / or metal ions having a metal complex having a redox ability of 1% by weight or more. Fibers supported in an amount of 1% by weight or more are 30 to 50% by weight, and ultrafine fibers having a high melting point of 0.5 denier or less and ultrafine fibers having a low melting point are 70 to 50% by weight. Since the low melting point ultrafine fibers are fused and the fibers are adhered to each other and the bowl-shaped shape is maintained, they have deodorant performance for a long period of time, and the deodorant fibers do not break and can be used with confidence. Moreover, the non-woven fabric constituting the mask body has a weight per unit area of 100 to 200 g / m 2 , a fiber density of 0.12 to 0.25 g / cm 3 , and an intake resistance of 2.0 to 3.0 mmH 2 O. Despite its excellent air permeability, it has a collection efficiency of 2 μm dust of 98% or more, and has a deodorant effect and prevents the passage of fine dust, which is extremely hygienic.
【0031】 そのうえマスク本体は、繊維間が一部の極細繊維の溶融によって接着されてな る不織布であるから、柔軟性と形態安定性に優れ、2つ折りしてコンパクな状態 に包装でき取り扱いが至便であり、上記した消臭および粉塵捕集効果と相まって 、化学工場や加工工場あるいは養鶏、畜産、農薬散布等悪臭環境下の作業者用と して好適となる。Moreover, since the mask body is a non-woven fabric in which some of the fibers are bonded by melting of some ultrafine fibers, it has excellent flexibility and morphological stability, and can be folded in two to be packaged in a compact state for easy handling. It is convenient, and combined with the above deodorizing and dust collecting effects, it is suitable for workers in chemical factories, processing factories, poultry farming, livestock, pesticide spraying, etc.
