Description
本発明は、クリーンルーム内での作業用衣料として利用でき、塵埃捕集効率に優れるにもかかわらず通気性が高く、快適な着用感が得られる防塵衣に関するものである。 The present invention relates to a dust-proof garment that can be used as a work garment in a clean room and has high breathability and a comfortable wearing feeling despite excellent dust collection efficiency.
半導体分野を始めとする各種エレクトロニクス分野においては、クリーンルーム内での製造が一般的であるが、近年その清浄度につき、ますます高度なものが要求されるようになってきている。これに対応すべく、クリーンルーム内の空気清浄化のためのフィルター開発とともに、クリーンルーム内の作業者の着用する防塵衣についても、種々の改良が施されてきている。 In various electronics fields including the semiconductor field, manufacturing in a clean room is common, but in recent years, more and more advanced products are required for the cleanliness. In order to cope with this, various improvements have been made to dust-proof clothing worn by workers in the clean room, along with the development of filters for cleaning the air in the clean room.
作業者から発生する塵埃としては、通常３種類のものが知られている。すなわち、
(1)防塵衣自体から発生する衣服発塵、
(2)作業者の人体自身および作業者が着用している肌着等から発生する塵埃であって防塵衣を透過してくる透過塵埃、
(3)作業者の人体自身および作業者が着用している肌着等から発生する塵埃であって衣服開口部から漏洩してくる漏洩塵埃
の３種類である。
Three types of dust are usually known as dust generated by workers. That is,
(1) Clothing dust generated from the dust proof clothing itself,
(2) Dust generated from the worker's human body and the underwear worn by the worker and transmitted through the dust-proof garment,
(3) There are three types of dust generated from the worker's human body and the underwear worn by the worker and leaking from the clothing opening.
前記３種の塵埃に対しては、各々対策がとられてきている。まず、上記(1)の衣服発塵対策として、自由端を有しない合成繊維の長繊維（いわゆるフィラメント繊維）が一般的に用いられるようになり、衣服発塵は、現在では通常はかなり低レベルを達成している。 Measures have been taken for each of the three types of dust. First of all, as a measure against clothing dust generation in (1) above, synthetic long fibers (so-called filament fibers) that do not have free ends are generally used. Has achieved.
また、上記(2)の透過発塵対策として、布帛の高密度化、あるいは布帛に目詰めの樹脂をコーティング処理することにより、通気度を減少させた布帛の開発が進み、これにより塵埃の通過を防止する方法が一般に用いられ、透過塵埃についても低レベルになってきている。 In addition, as a countermeasure against transmission dust generation in (2) above, the development of a fabric with reduced air permeability by increasing the density of the fabric or coating the fabric with a clogging resin has progressed, thereby allowing the passage of dust. In general, a method for preventing this is used, and the level of transmitted dust is also low.
さらに、上記(3)の漏洩塵埃対策として、衣服開口部を少なくする手法や、該開口部を締める方法や、エレクトレットシート状物を衣服開口部に取り付ける方法が提案されている。例えば、特開昭６２−３３８０６号公報（特許文献１）には、クリーンルーム内で着用され、かつ集塵装置により衣服本体内部の空気を吸引するようにした防塵衣であって、前記衣服の内側には、各々の先端部分が、襟元、袖口および裾などの各所にそれぞれ位置して前記集塵装置までの吸気流路を構成する複数の吸気管が設けられた防塵衣が開示されている。この防塵衣では、衣服本体内外の圧力差を生じさせることにより、衣服内部から汚染空気が排出されることを防止している。また、特開平６−１０１１０３号公報（特許文献２）には、伸縮性編物と非伸縮性編物から構成され、衿部及び袖口部が人体にフィットする構造を有する防塵衣において、少なくとも前記衿部と袖口部のいずれかに、通気性が１０〜１００ｃｍ／秒、２０％伸長時の塵埃捕集効率が７０％以上であり、特定のポリエステル長繊維で編製された伸縮性編物を使用する防塵衣が開示されている。 Furthermore, as a measure against the leakage dust of (3) above, there are proposed a method of reducing the clothing opening, a method of tightening the opening, and a method of attaching an electret sheet material to the clothing opening. For example, Japanese Patent Application Laid-Open No. 62-33806 (Patent Document 1) discloses a dust-proof garment worn in a clean room and sucking air inside a garment main body with a dust collector, Discloses a dust-proof garment provided with a plurality of intake pipes, each of which has a tip portion located at each position such as a neck, a cuff, and a hem, and constitutes an intake passage to the dust collector. In this dust-proof garment, a contaminated air is prevented from being discharged from the inside of the garment by creating a pressure difference between the inside and outside of the garment body. Japanese Patent Application Laid-Open No. 6-101103 (Patent Document 2) discloses a dust-proof garment that includes a stretch knitted fabric and a non-stretch knitted fabric and has a structure in which a heel portion and a cuff portion fit a human body. A dust-proof garment that uses a stretch knitted fabric knitted with a specific polyester long fiber and has a breathability of 10 to 100 cm / sec and a dust collection efficiency of 20% or more when stretched to 20% or more at any of the cuffs Is disclosed.
こうした透過発塵、漏洩発塵につき種々の対策が講じられ、それにより低レベルの発塵性を達成する防塵衣が開発されてきたが、その反面、着用快適性については満足するものはないのが実情である。なぜなら、塵埃捕集効率を高めるために通気度を減少させた防塵衣は、同時に人体からの水分の透過をも抑制するものであり、該防塵衣を着用して作業する作業者は、水分を封じ込められた非常な蒸し暑い、不快な着用感での作業を余儀なくされているからである。また、特殊な伸縮性編物を使用すると、圧迫感によって着用快適性が損なわれる。 Various measures have been taken for such permeation and leakage dust, and dust-proof clothing that achieves a low level of dust generation has been developed. However, on the other hand, there is nothing that satisfies the wearing comfort. Is the actual situation. This is because a dust-proof garment with reduced air permeability to increase dust collection efficiency also suppresses the permeation of moisture from the human body at the same time. This is because they are forced to work in a very sultry and uncomfortable wearing environment. In addition, when a special stretch knitted fabric is used, wearing comfort is impaired due to a feeling of pressure.
このような問題点を解消する技術として、一定水準以上の塵埃捕集効率を維持しつつ、通気度を上げて着用快適性を向上させるために、用いる長繊維の種類および、生地規格につき種々の検討がされている。例えば、特開平５−３２１０７５号公報（特許文献３）には、経糸又は緯糸の一方が沸水収縮率４％以下のポリエステルマルチフィラメント糸、他方がポリエステル異収縮混繊糸であって、経糸又は緯糸のカバーファクターの合計が２５００〜３５００である防塵性織物が提案されている。しかしながら、近年、さらに高度な塵埃捕集効率と、快適性が得られる一定以上の通気度とを同時に達成する防塵衣が求められており、この要求を満足するものは、現在では存在しないのが実情である。 As a technique for solving such problems, various types of long fibers and fabric standards are used in order to increase the air permeability and improve the wearing comfort while maintaining the dust collection efficiency above a certain level. Considered. For example, in JP-A-5-321075 (Patent Document 3), one of warp or weft is a polyester multifilament yarn having a boiling water shrinkage of 4% or less, and the other is a polyester different shrinkage mixed yarn, and the warp or weft A dustproof fabric having a total cover factor of 2500 to 3500 has been proposed. However, in recent years, there has been a demand for a dust-proof garment that simultaneously achieves a higher level of dust collection efficiency and a certain degree of air permeability that provides comfort, and there is currently no one that satisfies this requirement. It is a fact.
一方、特開平８−２８４０１１号公報（特許文献４）には、光触媒と吸着剤とを含有してなる消臭性繊維が開示されている。この文献には、光触媒として、酸化チタンなどの光半導体が記載され、吸着剤として、四価金属のリン酸塩および二価金属の水酸化物が記載されている。
従って、本発明の目的は、高い塵埃捕集効率と通気性とを同時に有する防塵衣を提供することにある。 Accordingly, an object of the present invention is to provide a dustproof garment having high dust collection efficiency and air permeability at the same time.
本発明の他の目的は、高い塵埃捕集効率を持ちながら、快適な着用感を実現でき、クリーンルーム内での使用に適した防塵衣を提供することにある。 Another object of the present invention is to provide a dust-proof garment suitable for use in a clean room that can realize a comfortable wearing feeling while having high dust collection efficiency.
本発明者らは、上記目的を達成すべく鋭意検討を行ってきた結果、光触媒と塵埃捕集剤とを含有する繊維を含む生地で防塵衣を調製すると、通気度を損なうことなく、高い塵埃捕集効率を達成できることを見出し、本発明を完成させることができた。 As a result of intensive studies to achieve the above object, the inventors of the present invention have prepared a dust-proof garment with a fabric containing a fiber containing a photocatalyst and a dust collecting agent. It was found that the collection efficiency could be achieved, and the present invention could be completed.

本発明における高度な塵埃捕集効率は、前記構成の捕集剤が、微量水分を有し、さらに光触媒との組み合わせにより発現するものと推定される。塵埃は、通常、粒子状であり、その粒径は、特に限定されず、例えば、数ミクロン以下程度である。一般に、粒径数ミクロン以下の塵埃微粒子では、その付着力は液架橋力が支配的となり、微量水分を有する捕集剤（例えば、四価金属のリン酸塩や二価金属の水酸化物）と、塵埃微粒子との間に水が介在する場合に、液架橋力により微粒子は効率的に捕集される。本発明では、捕集剤の有する微量水分が、光触媒効果による超親水化によって該捕集剤の表面にまんべんなく行き渡るため、微粒子は該捕集剤の表面に捕捉されやすくなり、高度の塵埃捕集効果が発現していると考えられる。捕集剤の有する水分量としては、例えば、捕集剤全体に対して、例えば、０．１〜２０重量％、好ましくは０．５〜１５重量％、さらに好ましくは０．８〜１０重量％程度である。 The high dust collection efficiency in the present invention is presumed that the collection agent having the above-described configuration has a trace amount of moisture and is expressed by a combination with a photocatalyst. Dust is usually particulate, and the particle size is not particularly limited, and is, for example, about several microns or less. In general, dust particles with a particle size of several microns or less have a liquid crosslinking ability as the adhesion force, and a trapping agent having a trace amount of water (for example, a tetravalent metal phosphate or a divalent metal hydroxide). And when water intervenes between the dust particles, the particles are efficiently collected by the liquid crosslinking force. In the present invention, the minute amount of water contained in the collection agent is evenly distributed on the surface of the collection agent by superhydrophilicity due to the photocatalytic effect, so that the fine particles are easily captured on the surface of the collection agent, and high-level dust collection. It is thought that the effect is manifested. The water content of the collection agent is, for example, 0.1 to 20% by weight, preferably 0.5 to 15% by weight, and more preferably 0.8 to 10% by weight with respect to the entire collection agent. Degree.
このように、本発明の防塵性繊維、防塵性生地、防塵衣は、前記光触媒と捕集剤との組み合わせを含むため、高い塵埃捕集力を有している。 Thus, since the dustproof fiber, dustproof cloth, and dustproof garment of the present invention include the combination of the photocatalyst and the trapping agent, they have a high dust trapping power.
防塵性繊維の製造方法には、結合剤を用いて光触媒及び捕集剤を繊維の表面に付着させる方法と、光触媒、捕集剤及び繊維形成性樹脂を含む樹脂組成物を紡糸する方法が含まれる。さらに、結合剤を用いる方法では、生地が調製される前の繊維に光触媒及び捕集剤を付着させてもよいし、繊維から生地を調製した後、生地に光触媒及び捕集剤を付着させてもよい。 The dust-proof fiber manufacturing method includes a method of attaching a photocatalyst and a collecting agent to the surface of the fiber using a binder, and a method of spinning a resin composition containing the photocatalyst, the collecting agent and a fiber-forming resin. It is. Furthermore, in the method using a binder, the photocatalyst and the collecting agent may be attached to the fibers before the dough is prepared, or after the dough is prepared from the fibers, the photocatalyst and the collecting agent are attached to the dough. Also good.
結合剤を用いる方法は、特に限定されないが、例えば、接着性樹脂などの結合剤を用いて繊維又は生地の表面から光触媒及び捕集剤が脱落しないように付着させる方法、結合剤を塗布した繊維又は生地の表面に光触媒及び捕集剤を付着させる方法、光触媒と捕集剤と必要に応じて結合剤とを含む分散液に繊維又は生地を含浸させる方法、前記分散液を繊維又は生地に噴霧、コーティングする方法など慣用の手法が採用できる。 The method using the binder is not particularly limited, but, for example, a method using a binder such as an adhesive resin to attach the photocatalyst and the collecting agent from the surface of the fiber or fabric so that the fiber does not fall off, or a fiber coated with the binder. Alternatively, a method of attaching a photocatalyst and a collection agent to the surface of the fabric, a method of impregnating a fiber or fabric with a dispersion containing the photocatalyst, a collection agent and, if necessary, a binder, and spraying the dispersion onto the fiber or fabric.

You may make it contain and incline in the radial direction. In particular, from the viewpoint of dust collection efficiency, it is preferable to have a photocatalyst and a collecting agent on at least the fiber surface (or the fabric surface). Therefore, a layer (for example, 0.1 to 50% by weight, preferably 0.5 to 30% by weight, more preferably 1 to 20% by weight) having a high concentration of the photocatalyst and the collecting agent and a layer having a low concentration (for example, 0 to 10% by weight, preferably 0-5% by weight, more preferably 0-1% by weight) of a composite fiber having a composite structure, for example, a high-concentration layer is disposed on the fiber surface (so-called sheath) And the core-sheath-type composite fiber which arrange | positioned the layer which does not contain a photocatalyst and a scavenger at a low density | concentration or a core may be sufficient. Such a core-sheath structure composite fiber can maintain the strength of the fiber and exhibit a high dustproof effect.

In order to increase dust collection efficiency, a modified cross-section fiber having a large specific surface area is advantageous. Furthermore, the fiber which combined the said composite structure and the unusual shape structure may be sufficient. The thickness of the single fiber is, for example, about 0.5 to 5 dtex, preferably about 1 to 4 dtex, from the viewpoint of dustproof effect and comfort. Further, when the fibers are used in the state of long fibers, the multifilament thickness is, for example, 56 to 220 dtex, preferably 70 to 200 dtex, and more preferably, in order to configure a fabric thickness suitable for dustproof clothing.

The weight per unit area of the fabric (basis weight), in terms of air permeability and dust-proof effect, when the fabric is woven, for example, 50 to 300 g / m 2, preferably 70~250g / m 2 More preferably, it is about 100 to 200 g / m 2 . In a fabric having such a weight per unit area, for example, when 50-120 dtex (especially 70-100 dtex) is used for the warp and 125-200 dtex (especially 140-180 dtex) is used for the weft, the warp density is 142-182. The book / inch and the weft density are preferably about 85 to 105 / inch.
また、生地中には、目的に応じて、静電気による帯電を防止するため、導電性を付与してもよい。導電性を付与する方法としては、後加工（導電性成分の塗布など）によって帯電防止性を付与してもよいが、脱落による衣服発塵を防止する点から、導電糸を用いる方法が好ましい。導電糸としては、一般的には、耐久性の高い導電性繊維、例えば、導電剤（例えば、導電性カーボンブラック、黒鉛粉末、金属粉末、炭素繊維など）を練り込んだ導電ポリマーを芯成分とし、強度保持性に優れたポリマーを鞘成分とする芯鞘型複合繊維を含む糸などが挙げられる。導電性繊維中の導電剤の含有量は、導電性繊維１００重量部に対して、例えば、０．１〜２０重量部、好ましくは０．５〜１０重量部、さらに好ましくは１〜５重量部程度である。さらに、導電剤を含有するポリマーを芯成分とする前記芯鞘型複合繊維の場合、芯成分中における導電剤の割合は、例えば、１５〜６０重量％、好ましくは２０〜５５重量％程度である。さらに、導電性繊維の切断を抑制する点から、３〜２０本（特に５〜１８本）程度のマルチフィラメントとして、布帛中に一定間隔で織り込むか、編み込むのが好ましい。導電糸の割合としては、目的とする帯電防止効果に応じて、１本／インチまたはそれ以上の密なピッチ、例えば、マルチフィラメントを１本として、２０〜１本／インチ、好ましくは１０〜１．２本／インチ、さらに好ましくは５〜１．５本／インチ程度で生地中に導入してもよい。 In addition, the fabric may be provided with conductivity in order to prevent charging due to static electricity depending on the purpose. As a method for imparting conductivity, antistatic properties may be imparted by post-processing (such as application of a conductive component). However, a method using conductive yarn is preferable from the viewpoint of preventing clothes from being dusted by falling off. As the conductive yarn, generally, a highly durable conductive fiber, for example, a conductive polymer kneaded with a conductive agent (for example, conductive carbon black, graphite powder, metal powder, carbon fiber, etc.) is used as a core component. And a yarn containing a core-sheath type composite fiber having a polymer excellent in strength retention as a sheath component. The content of the conductive agent in the conductive fiber is, for example, 0.1 to 20 parts by weight, preferably 0.5 to 10 parts by weight, more preferably 1 to 5 parts by weight with respect to 100 parts by weight of the conductive fiber. Degree. Furthermore, in the case of the core-sheath type composite fiber having a core component of a polymer containing a conductive agent, the proportion of the conductive agent in the core component is, for example, about 15 to 60% by weight, preferably about 20 to 55% by weight. . Further, from the viewpoint of suppressing the cutting of the conductive fibers, it is preferable to weave or knit the fabric as a multifilament of about 3 to 20 (particularly 5 to 18) at regular intervals. The ratio of the conductive yarn is 20-1 / inch, preferably 10-1 with a dense pitch of 1 / inch or more, for example, one multifilament, depending on the intended antistatic effect. .2 / inch, more preferably 5 to 1.5 / inch, may be introduced into the dough.

［防塵衣］
本発明の防塵衣は、前記生地（防塵性生地）で構成されている。また、防塵衣に用いる生地の厚みは発明の目的効果を損なわない範囲で防塵衣用の生地に使用できる範囲であれば特に限定はしないし、本発明の効果を損なわない範囲で別の生地やシートを積層してもよい。織物の場合、生地の厚みは、通常、室温（１５〜２５℃程度）、２３．５ｋＰａの押圧下で、例えば、０．１２〜０．５ｍｍ、好ましくは０．１５〜０．４ｍｍ、さらに好ましくは０．２〜０．３ｍｍ程度である。
[Dust-proof clothing]
The dustproof garment of the present invention is composed of the fabric (dustproof fabric). In addition, the thickness of the fabric used for the dust-proof garment is not particularly limited as long as it can be used for the fabric for the dust-proof garment within a range that does not impair the object effect of the invention. Sheets may be laminated. In the case of a woven fabric, the thickness of the fabric is usually 0.12 to 0.5 mm, preferably 0.15 to 0.4 mm, and more preferably under a pressure of 23.5 kPa at room temperature (about 15 to 25 ° C.). Is about 0.2 to 0.3 mm.
なお、本発明の防塵衣において、いずれの部位も同一の生地で構成されている必要はなく、発塵しやすくかつ通気性が要求される部位に、防塵性生地を用い、他の部位には従来の防塵衣に用いられている生地を用いたものでもよく、また発塵しやすくかつ通気性が要求される部位に防塵性繊維が多量に用いられている防塵性生地を用い、他の部位には防塵性繊維が少量使用されている防塵性生地を用いることも可能である。 In addition, in the dust-proof garment of the present invention, it is not necessary that any part is made of the same fabric, dust-proof fabric is used for parts that are easy to generate dust and breathability is required, and other parts are used. It may be one that uses the cloth used in conventional dust-proof clothing, and other parts using dust-proof cloth that is easy to generate dust and that requires a large amount of dust-proof fiber in parts that require breathability It is also possible to use a dustproof fabric in which a small amount of dustproof fiber is used.
本発明の防塵衣において、生地の通気度は、例えば、８〜１００ｃｍ／秒、好ましくは９〜８０ｃｍ／秒、さらに好ましくは１０〜５０ｃｍ／秒程度である。通気度が小さすぎると、防塵衣の着用時にムレ感がつよく、本発明の目的とする快適な着用感は得られにくい。また、通気度が大きすぎると、同時に高度な塵埃捕集効率を得ることが困難となる。本発明でいう通気度は、ＪＩＳ−Ｌ−１０９６．２７．Ａ法（フラジール法）により測定される。通気度は、生地を構成する繊維の太さ、糸の太さ、生地の織り密度、生地の単位面積当たりの重さ等により自由に変えることができる。 In the dust-proof garment of the present invention, the air permeability of the fabric is, for example, about 8 to 100 cm / second, preferably about 9 to 80 cm / second, and more preferably about 10 to 50 cm / second. When the air permeability is too small, the feeling of stuffiness is strong when the dust-proof garment is worn, and it is difficult to obtain a comfortable wearing feeling as an object of the present invention. If the air permeability is too high, it is difficult to obtain a high dust collection efficiency at the same time. The air permeability referred to in the present invention is JIS-L-1096.27. It is measured by A method (Fragile method). The air permeability can be freely changed according to the thickness of the fibers constituting the fabric, the thickness of the yarn, the weave density of the fabric, the weight per unit area of the fabric, and the like.
本発明の防塵衣において、生地の塵埃捕集効率は、高いほど塵埃発生を抑制できるためより高い効率が好ましく、例えば、７０％以上（例えば、７０〜１００％）、好ましくは７５％以上（例えば、７５〜９９％）、さらに好ましくは８０％以上（例えば、８０〜９５％）程度である。塵埃捕集効率が低すぎると、防塵衣の防塵性としては不十分である。特に、塵埃捕集効率が８０％以上であると、有効に塵埃の発生を抑制でき、例えば、クリーンルーム内などの高度な塵埃捕集効率を要求される用途でも使用が可能となる。本発明でいう塵埃捕集効率は、以下の手法で測定される。直径２５ｃｍ、高さ２５ｃｍの円錐に測定する試料生地をセットし、吸引量２．８３リットル／分にて通過した粒径０．３μｍ以下の大気中の塵埃濃度（Ａ）をパーティクルカウンターで測定する。測定直後、円錐より試料生地を取り除き、同様に吸引量２．８３リットル／分にて通過した粒径０．３μｍ以下の大気中の塵埃濃度（Ｂ）をパーティクルカウンターで測定する。それぞれの濃度Ａ、Ｂより、塵埃捕集効率は次式で計算される。 In the dust-proof garment of the present invention, the higher the dust collection efficiency of the fabric, the higher the efficiency because dust generation can be suppressed. 75 to 99%), more preferably about 80% or more (for example, 80 to 95%). If the dust collection efficiency is too low, it is insufficient as a dustproof property of the dustproof garment. In particular, when the dust collection efficiency is 80% or more, the generation of dust can be effectively suppressed, and for example, it can be used in applications requiring high dust collection efficiency such as in a clean room. The dust collection efficiency referred to in the present invention is measured by the following method. A sample cloth to be measured is set in a cone having a diameter of 25 cm and a height of 25 cm, and the dust concentration (A) in the atmosphere having a particle diameter of 0.3 μm or less that has passed at a suction amount of 2.83 liters / minute is measured with a particle counter. . Immediately after the measurement, the sample dough is removed from the cone, and the dust concentration (B) in the atmosphere having a particle size of 0.3 μm or less that has been passed at a suction amount of 2.83 liters / minute is measured with a particle counter. From the respective concentrations A and B, the dust collection efficiency is calculated by the following equation.
塵埃捕集効率（％）＝（１−Ａ／Ｂ）×１００
尚、塵埃濃度（Ｂ）を測定する直前に、塵埃濃度（Ｂ）の測定方法と同様の方法で、予め、塵埃濃度（Ｂ0）を測定してもよい。予め測定した塵埃濃度（Ｂ0）を塵埃濃度（Ｂ）と比較して、両者の濃度差が大きい場合には、再測定を行い測定精度を高めるのが好ましい。
Dust collection efficiency (%) = (1−A / B) × 100
Note that immediately before the dust concentration (B) is measured, the dust concentration (B 0 ) may be measured in advance by the same method as the dust concentration (B) measurement method. When the dust concentration (B 0 ) measured in advance is compared with the dust concentration (B), if the density difference between the two is large, it is preferable to perform re-measurement to increase the measurement accuracy.
本発明の防塵衣は、例えば、アレルギー疾患などの予防の観点などから、塵埃の発生を抑制するために、日用や病院用の衣類や身体着用品（肌着、下着、セーター、ジャケット、パジャマ、浴衣、白衣、スラックス、靴下、手袋、ストッキング、エプロン、帽子などの衣類や、マスク、タオル、ハンカチなど）として使用してもよいが、高度な塵埃捕集効率と通気性を要求される用途、例えば、半導体分野などの各種エレクトロニクス分野におけるクリーンルーム内で使用される衣類や身体着用品（作業衣、帽子、手袋などの衣類や、マスク、タオルなど）として使用するのに適している。例えば、クリーンルーム内での作業衣としては、クリーンルームの清浄度レベルによって、続き服とライフセーバー付き頭部フードとを組み合わせた吸引システム併用型の高性能タイプから、一般的な上下服フード付き、さらに上下服の汎用タイプなどがあり、本発明の防塵衣はこれら全種類にわたり適用可能である。 The dust-proof garment of the present invention is, for example, from the viewpoint of prevention of allergic diseases and the like, in order to suppress the generation of dust, daily and hospital clothing and body wear items (underwear, underwear, sweaters, jackets, pajamas, Yukata, white robe, slacks, socks, gloves, stockings, aprons, hats, etc., masks, towels, handkerchiefs, etc.), but applications that require high dust collection efficiency and breathability, For example, it is suitable for use as clothing and body wear items (clothes such as work clothes, hats and gloves, masks, towels, etc.) used in clean rooms in various electronics fields such as the semiconductor field. For example, for work clothes in a clean room, depending on the cleanliness level of the clean room, from a high-performance type with a suction system that combines continuous clothes and a head hood with a life saver, with a general upper and lower clothes hood, There are general-purpose types of upper and lower clothes, and the dustproof garment of the present invention can be applied to all of these types.

To the DMIS-modified polybutylene terephthalate, 3.5% by weight of the composition obtained above was added and extruded while kneading by a conventional method to prepare pellets. By spinning the pellets and regular PET for fibers (polyethylene terephthalate) in a sheath and a core, respectively, by a core-sheath type melt composite spinning method arranged at a weight ratio of 50/50, and further drawing and false twisting A core-sheath type composite filament processed yarn (167 dtex, 48 filaments) was obtained.
［生地の製造］
上記にて調製した芯鞘型複合フィラメント加工糸を緯糸に、レギュラーポリエステル加工糸（１１０デシテックス、４８フィラメント、撚数：１００Ｔ／ｍ）を経糸に用い、２／３ツイル組織にて目付け１２８ｇ／ｍ2の生地を得た。該生地の塵埃捕集効率は５４．５％、通気度は１３．８ｃｍ／秒であった。
[Production of dough]
The core-sheath type composite filament processed yarn prepared above is used as the weft, and the regular polyester processed yarn (110 dtex, 48 filaments, twist: 100 T / m) is used as the warp, and the basis weight is 128 g / m with a 2/3 twill structure. 2 doughs were obtained. The dust collection efficiency of the fabric was 54.5%, and the air permeability was 13.8 cm / second.
比較例３
前記ＤＭＩＳ変性ポリブチレンテレフタレートに、光触媒活性を有するアナターゼ型酸化チタンを２重量％添加し、常法で混練しつつ押し出し、ペレットを調製した。該ペレットと、繊維用レギュラーＰＥＴ（ポリエチレンテレフタレート）とを各々鞘と芯に、鞘／芯＝５０／５０（重量比率）にて配置した芯鞘型溶融複合紡糸手法により紡糸し、さらに延伸・仮撚加工することにより、芯鞘型複合フィラメント加工糸（１６７デシテックス、４８フィラメント）を得た。該芯鞘型複合フィラメント加工糸を緯糸に、レギュラーポリエステル加工糸（１１０デシテックス、４８フィラメント）を経糸に用い、２／３ツイル組織にて目付け１２９ｇ／ｍ2の生地を得た。該生地の塵埃捕集効率は２７％、通気度は１５．４ｃｍ／秒であった。
Comparative Example 3
To the DMIS-modified polybutylene terephthalate, 2% by weight of anatase-type titanium oxide having photocatalytic activity was added and extruded while kneading by a conventional method to prepare pellets. The pellets and regular PET for fibers (polyethylene terephthalate) were spun by a core-sheath melt composite spinning method in which the sheath and the core were arranged at a sheath / core = 50/50 (weight ratio), respectively. The core-sheath type composite filament processed yarn (167 dtex, 48 filaments) was obtained by twisting. Using the core-sheath type composite filament processed yarn as the weft and the regular polyester processed yarn (110 dtex, 48 filament) as the warp, a fabric having a basis weight of 129 g / m 2 was obtained with a 2/3 twill structure. The dough had a dust collection efficiency of 27% and an air permeability of 15.4 cm / sec.
表１に示すとおり、実施例１〜３で得られた防塵衣は、実際に販売使用されている比較例１で得られた防塵衣よりもさらに高い塵埃捕集効率を有しており、同時に高い通気度も達成している。また、実施例１〜３の結果から明らかなように、光触媒と捕集剤とを含有した芯鞘複合フィラメント加工糸（１６７デシテックス、４８フィラメント）は、必ずしも１００％用いる必要はなく、実施例１及び３のように緯糸のみ、あるいは実施例２のように、緯糸の一部に使用することで、本発明の目的を達成することができる。さらに、比較例２及び３の結果から明らかなように、光触媒を単独使用した場合や、捕集剤を単独使用した場合には、実施例１〜３に示す高い塵埃捕集効率を達成できない。従って、光触媒と捕集剤の複合化により、本発明における高い塵埃捕集効果が発現することがわかる。 As shown in Table 1, the dust proof clothing obtained in Examples 1 to 3 has a higher dust collection efficiency than the dust proof clothing obtained in Comparative Example 1 that is actually sold and used. High air permeability is also achieved. Further, as is apparent from the results of Examples 1 to 3, the core-sheath composite filament processed yarn (167 dtex, 48 filaments) containing the photocatalyst and the collecting agent is not necessarily used at 100%. The object of the present invention can be achieved by using only the wefts as in No. 3 and No. 3, or a part of the weft as in Example 2. Furthermore, as is clear from the results of Comparative Examples 2 and 3, the high dust collection efficiency shown in Examples 1 to 3 cannot be achieved when the photocatalyst is used alone or when the collection agent is used alone. Therefore, it can be seen that the high dust collection effect in the present invention is manifested by the combination of the photocatalyst and the collection agent.
