Description
【０００１】
【発明の属する技術分野】
本発明はイオン性物質除去衣料に関する。
【０００２】
【従来の技術】
従来、クリーンルーム内等、作業雰囲気を清浄に保つ必要のある区域では、作業者は塵の発生しないような無塵服を着て作業を行っている。
【０００３】
【発明が解決しようとする課題】
ところで、近年、半導体製造等の分野の精密機器を取り扱うような環境下では、雰囲気中に塵の発生が無いことに加え、揮散するイオン性物質についても除去しておくべきであるとの必要性が指摘されはじめている。しかし、従来の無塵衣には上述のようなイオン性物質を除去する機能はなく、イオン性物質を除去する技術が望まれていた。
【０００４】
そこで、本発明の目的は、作業雰囲気中に揮散、あるいは飛散するイオン成分を簡便かつ確実に除去可能な技術を提供することにある。
【０００５】
【課題を解決するための手段】
本発明は、衣料をイオン交換繊維で形成し、イオン性物質除去を含有してなる従来にない衣料を提供することにより、作業時にその衣料を身につけることで、作業者の発汗等に基づくイオンの揮散を防止出来るのではないかと本発明者らが考え至り、成されたものである。
【０００９】
〔構成〕
また、イオン性物質除去衣料を、陽イオン交換繊維を含んでなる繊維材料から紡織してある、織布と、陰イオン交換繊維を含んでなる繊維材料から紡織してある、織布とを、重ね合わせ、分割自在に一体形成してあることを特徴としてあってもよ良い。
〔作用・効果〕
つまり、上述のイオン性物質除去衣料を人体に着用させると、人体は陽イオン交換繊維を含んでなる織布と、陰イオン交換繊維を含んでなる織布との両織布におおわれていることになるから、人体から発生したイオン性物質は陽、陰イオンとも雰囲気中に放出されるまでに吸着除去され易くなり、イオン性物質の放出をより確実に防止し易い。また、前記両織布は分割自在に一体形成してあることから、前記イオン性物質除去衣料の使用後には前記両織布を分割して、各別に再生させることにより、再利用可能になり、前記イオン性物質除去衣料の長期利用等に役立つ。
【００１０】
〔構成〕
また、前記目的を達成する本発明イオン性物質除去衣料の製造方法の特徴構成は、イオン交換繊維を含んでなる繊維材料を、前記繊維材料中のイオン交換繊維のイオン交換基を、イオン交換して塩型とした状態で織物を紡織したのち、前記イオン交換基の劣化しにくい低温条件下で、塩型の前記イオン交換基を元のイオン交換基に再生することにある。
【００１１】
〔作用効果〕
つまり、イオン交換繊維を含んでなるなる繊維材料をそのまま紡織に用いれば紡織の工程中で、前記イオン交換基に紡織作業雰囲気中のイオン性物質や、紡織工程で用いる糊材や油材中のイオン性物質が結合してしまって、再生困難になる虞れがあるのに対し、前記イオン交換基に結合・脱離容易なイオン性物質を結合させ、塩型として紡織するので、前記イオン交換基は再生困難になるような状況になりにくく、また、イオン交換繊維は高温に晒されるとイオン交換基が分解して劣化することが考えられているのに対し、そのイオン交換基が劣化する虞れのある温度（例えば、強酸性陽イオン交換繊維では９０℃程度）よりも低温の劣化しにくい条件下（例えば、強酸性陽イオン交換繊維に対して７０〜８０℃程度）で先の塩型のイオン交換基を元のイオン交換基に再生すれば（例えば、強酸性陽イオン交換繊維を酸に晒せば）、イオン交換性能の極めて高いイオン性物質除去衣料を形成することが出来ることになり、そのイオン性物質除去衣料を使用しはじめてから再生が必要になるまでの期間を長く設定し易い。
【００１２】
つまり、人体から揮散するイオン性物質を確実に捕捉しやすくなって、イオン性物質を揮散あるいは飛散させにくくなり、雰囲気を清浄に保ち易くなる。また、再生作業を行う頻度を少なく出来るので、再生作業を行うための化学処理等に労力を軽減出来、ランニングコストを安価に設定できる。
【００１３】
【発明の実施の形態】
以下に本発明のイオン性物質除去衣料をその製造方法とともに説明する。
＜１＞ 陽イオン性物質除去衣料
縦糸として４００〜５００デニールのポリエステルより糸、横糸としてポリエステル繊維２本に対して１の割合で８デニールの塩型（イオン交換基をナトリウム塩型にしてあるもの）の強酸性陽イオン交換繊維（イオン交換当量２．０ｍｅｑ／ｇのもの）を３０本よりあわせてなる２４０デニールの糸を２〜３本寄り合わせてサイジング材（糊剤・油剤）で処理したものを用いて織布を紡織し、その織布を用いて衣料を形成した。この衣料は１２０ｍｅｑ／ｍ2 の総交換当量のイオン交換基を有するものとなった。この衣料を６０〜７０℃の温水で洗浄し、サイジング剤を除去し、さらに、２％塩酸で十分洗浄してイオン交換基を再生し、更に、純水で洗浄、乾燥してイオン性物質除去衣料とした。
【００１４】
このイオン性物質除去衣料に用いた織布を、イオン交換性能の無い通常の生地（ガーゼ）を介して作業者に密着させ、かつ、表面側をガス非透過性のフィルムで覆った状態で、その作業者が２４時間の事務作業を行ったのち、前記織布を回収して各種イオンの吸着量を調べたところ、表１のようになった。尚、前記表中ブランクとあるのは使用前の織布が元来保有していたイオン量にあたるものである。
【００１５】
【表１】
表１より、人体から揮散あるいは飛散するアンモニア成分に由来するアンモニウムイオン等のイオン性物質は、十分に捕捉除去出来ているものと言える。また、上述の織布のイオン交換当量から、上述のイオン交換衣料は１８０日の使用につき１度の再生を行えばイオン性物質の揮散を防止しつつ繰り返し利用が可能なものとなっていることがわかる。
【００１７】
＜２＞ 陰イオン性物質除去衣料
縦糸として４００〜５００デニールのポリエステルより糸、横糸としてポリエステル繊維２本に対して１本の割合で８デニールの塩型（イオン交換基を塩素塩型にしてあるもの）の強塩基性陰イオン交換繊維（イオン交換当量３．６ｍｅｑ／ｇのもの）を３０本よりあわせてなる２４０デニールの糸を２〜３本寄り合わせてサイジング剤（糊剤・油剤）で処理したものを用いて織布を紡織し、その織布を用いて衣料を形成した。この衣料は２１６ｍｅｑ／ｍ2 の総交換当量のイオン交換基を有するものとなった。この衣料を４０℃の温水で洗浄し、サイジング剤を除去し、さらに、０．５〜５ｗｔ％の水酸化ナトリウム水溶液で十分洗浄してイオン交換基を再生し、更に、純水で洗浄、乾燥してイオン性物質除去衣料とした。
【００１８】
このイオン性物質除去衣料に用いた織布を、＜１＞と同様にして各種イオンの吸着量を調べたところ、表２のようになった。
【００１９】
【表２】
表２より、陰イオン性物質除去衣料についても、人体から揮散あるいは飛散する塩化物イオン等のイオン性物質は、十分に捕捉除去出来ているものと言える。
【００２１】
〔別実施形態〕
以下に別実施形態を説明する。
先の実施の形態ではイオン交換繊維を横糸のみに用いたが縦糸にも用いてもよく、逆に、より糸中の一部のみをイオン交換繊維としてあってもよく上述の構成に限るものではない。
さらに、イオン交換繊維のとして、強酸性陽イオン交換繊維、弱酸性陽イオン交換繊維、強塩基性陰イオン交換繊維、弱塩基性陰イオン交換繊維のいずれをもちいることも出来る。
また、衣料の形態としては、下着、上着、いずれに用いてもよく、陽イオン性物質除去衣料と、陰イオン性物質除去衣料とを重ね着して用い、人体から揮散するイオン性物質を確実に捕捉する構成で使用することが望ましい。
【００２２】
さらに、＜１＞に用いた織布及び＜２＞に用いた織布の一方を衣料の表地、他方を衣料の裏地に用いる等して、イオン性物質除去衣料を形成してあってもよい。この場合、表地と裏地を各別に再生することが出来るようになり、前記イオン性物質除去衣料が長期使用により、性能低下する等の不都合が生じたとしても再生再利用が出来るので好都合である。
【００２３】
尚、紡織の工程については、種々周知の方法を採用でき、粘剤や、油剤の種類や有無は問わないものとする。[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an ionic substance-removing garment.
[0002]
[Prior art]
Conventionally, in an area where the working atmosphere needs to be kept clean, such as in a clean room, an operator wears dust-free clothing that does not generate dust.
[0003]
[Problems to be solved by the invention]
By the way, in recent years, in an environment where handling precision equipment in the field of semiconductor manufacturing and the like, in addition to the absence of dust generation in the atmosphere, the necessity of removing volatile ionic substances should also be removed Has begun to be pointed out. However, conventional dust-free garments have no function of removing ionic substances as described above, and a technique for removing ionic substances has been desired.
[0004]
Accordingly, an object of the present invention is to provide a technique capable of easily and reliably removing ion components that are volatilized or scattered in a working atmosphere.
[0005]
[Means for Solving the Problems]
The present invention provides an unprecedented garment formed by forming an garment with ion exchange fibers and containing ionic substance removal, thereby wearing the garment at the time of work, and based on sweating of an operator. The present inventors have come up with the idea that the volatilization of ions can be prevented.
[0009]
〔Constitution〕
An ionic substance-removing garment is woven from a fiber material comprising a cation exchange fiber, and a woven fabric is woven from a fiber material comprising an anion exchange fiber. It may be characterized by being integrally formed so as to be superposed and divided.
[Action / Effect]
That is, when the above-mentioned ionic substance-removed garment is worn on the human body, the human body is covered with both woven fabrics including a woven fabric including cation exchange fibers and a woven fabric including anion exchange fibers. Therefore, the ionic substance generated from the human body is easily adsorbed and removed before both positive and negative ions are released into the atmosphere, and the release of the ionic substance is more easily prevented. In addition, since both the woven fabrics are integrally formed so as to be detachable, after the use of the ionic substance-removable garment, the two woven fabrics are divided and regenerated separately to be reusable. This is useful for long-term use of the ionic substance-removed clothing.
[0010]
〔Constitution〕
The feature structure of the present invention the ionic substance removing clothing manufacturing method to achieve the object, a fiber維材fee ing include ion exchange fiber, ion-exchange groups of the ion exchange fibers of the fibrous material, ion It is to regenerate the salt-type ion exchange group to the original ion-exchange group under a low temperature condition in which the ion-exchange group is not easily deteriorated after the fabric is spun in the state of being exchanged to form a salt form.
[0011]
[Function and effect]
In other words, if a fiber material comprising ion exchange fibers is used for spinning as it is, in the spinning process, ionic substances in the textile working atmosphere in the ion exchange group, and paste materials and oil materials used in the spinning process. While there is a possibility that the ionic substance is bound and it becomes difficult to regenerate, the ionic substance that is easily bonded and desorbed is bonded to the ion exchange group, and the ionic substance is spun as a salt form. The group is unlikely to be in a situation that makes it difficult to regenerate, and the ion exchange fiber is considered to decompose and deteriorate when exposed to high temperatures, whereas the ion exchange group deteriorates. The previous salt under conditions that are unlikely to deteriorate at a lower temperature (for example, about 70 to 80 ° C. for strongly acidic cation exchange fibers) than the temperature at which there is a fear (for example, about 90 ° C. for strong acid cation exchange fibers) Type ion exchange If the group is regenerated to the original ion exchange group (for example, if a strongly acidic cation exchange fiber is exposed to an acid), an ionic substance-removed garment with extremely high ion exchange performance can be formed. It is easy to set a long period from the beginning of using the sex material removal clothing until it becomes necessary to regenerate.
[0012]
That is, it becomes easy to surely capture the ionic substance volatilized from the human body, it is difficult to volatilize or scatter the ionic substance, and it becomes easy to keep the atmosphere clean. Further, since the frequency of performing the regenerating work can be reduced, the labor can be reduced in the chemical processing for performing the regenerating work, and the running cost can be set at a low cost.
[0013]

From Table 1, it can be said that ionic substances such as ammonium ions derived from the ammonia component volatilized or scattered from the human body are sufficiently captured and removed. In addition, from the ion exchange equivalent of the above-mentioned woven fabric, the above-mentioned ion exchange garment can be repeatedly used while preventing volatilization of ionic substances if it is regenerated once per 180 days of use. I understand.
[0017]
<2> Anionic substance-removed clothing warp yarn of 400 to 500 denier polyester yarn, weft yarn is 8 denier salt type for two polyester fibers (the ion exchange group is a chlorine salt type) ) Of strongly basic anion exchange fibers (with an ion exchange equivalent of 3.6 meq / g), two to three 240 denier yarns are combined and treated with a sizing agent (glue agent / oil agent). A woven fabric was spun using the resulting fabric, and clothing was formed using the woven fabric. This garment had ion exchange groups with a total exchange equivalent of 216 meq / m 2 . This clothing is washed with warm water of 40 ° C., the sizing agent is removed, and further washed with an aqueous solution of 0.5 to 5 wt% sodium hydroxide to regenerate the ion exchange groups, and further washed with pure water and dried. Thus, an ionic substance removing garment was obtained.
[0018]
The woven fabric used for this ionic substance-removed garment was examined for adsorption amounts of various ions in the same manner as in <1>.
[0019]
[Table 2]
From Table 2, it can be said that ionic substances such as chloride ions that are volatilized or scattered from the human body are sufficiently captured and removed from the anionic substance-removed clothing.
[0021]
[Another embodiment]
Another embodiment will be described below.
In the previous embodiment, ion exchange fibers were used only for weft yarns, but they may also be used for warp yarns. Conversely, only a part of the yarns may be used as ion exchange fibers, and the present invention is not limited to the above-described configuration. .
Further, as the ion exchange fiber, any of strong acid cation exchange fiber, weak acid cation exchange fiber, strong basic anion exchange fiber, and weak basic anion exchange fiber can be used.
Moreover, as a form of clothing, it may be used for both underwear and outerwear, and an ionic substance that volatilizes from the human body is used by layering a cation substance-removed garment and an anionic substance-removed garment. It is desirable to use in a configuration that reliably captures.
[0022]
