この発明は、殺菌作用を有する金属ゼオライトを中空糸
自体に含有せしめることにより、抗菌ならびに防カビの
機能を付与した多孔質中空糸に関するものである。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a porous hollow fiber that has antibacterial and antifungal functions by incorporating metal zeolite, which has a bactericidal effect, into the hollow fiber itself. be.
従来より、医療・医薬品用、食品工業用、超Ｌ３１製造
等の先端産業用、あるいは飲料水等一般家庭用として多
種多様の純水製造装置が提案されているが、それらのほ
とんどは多孔質中空糸を濾過モジュールに用いたもので
ある。A wide variety of pure water production devices have been proposed for medical and pharmaceutical use, food industry, cutting-edge industries such as ultra-L31 production, and general household use such as drinking water, but most of them are porous hollow water purification devices. The thread is used in the filtration module.
ところで、−Ｓの高分子多孔質中空糸を用いた純水製造
装置では、使用しているうちに水中に混入していたゴミ
、泥、砂などの浮遊混入物が中空糸とりわけその表面に
堆積し、それらが細菌繁殖の温床となって中空糸の濾過
性能低下や耐久性及び衛生上の障害となっている。By the way, in pure water production equipment using -S polymer porous hollow fibers, during use, floating contaminants such as dirt, mud, and sand that are mixed into the water accumulate on the hollow fibers, especially on their surfaces. However, these become a breeding ground for bacteria, resulting in a decrease in the filtration performance of the hollow fibers and impeding durability and hygiene.
これを阻止するために薬品を用いたり、紫外線を照射し
て濾過モジュールの殺菌を行う等の方法も一部では試み
られているが、作業を定期的に繰り返す必要があるため
煩わしく、経済性の面でもコスト高とならざるを得ない
。Some methods have been tried to prevent this, such as using chemicals or sterilizing the filtration module by irradiating it with ultraviolet rays, but these are cumbersome and uneconomical as they require periodic repetition. This inevitably leads to higher costs.
この発明は、上述したような課題を解消するためになさ
れたもので、殺菌作用を有する金属を保持したゼオライ
トを少なくとも１重量％以上、中空糸自体に含有せしめ

付与したものである。This invention was made in order to solve the above-mentioned problems, and by containing at least 1% by weight of zeolite holding a metal with a bactericidal effect in the hollow fiber itself, the porous hollow fiber has antibacterial and antibacterial properties. It has an anti-mold function.
中空糸自体に殺菌性を有するゼオライトを混入すること
により、通水時・通水停止時を問わず恒久的に中空糸に
殺菌作用を付与することができる。By mixing zeolite, which has bactericidal properties, into the hollow fiber itself, it is possible to permanently impart a bactericidal action to the hollow fiber, regardless of whether water is flowing or not.
このため、濾過物における細菌の繁殖やカビの発生を防
止することが可能となる。Therefore, it is possible to prevent the proliferation of bacteria and the generation of mold in the filtrate.
以下この発明の実施例を添付図面にもとづいて詳細に説

ある。Embodiments of the present invention will be described in detail below based on the accompanying drawings. In the figure, (1) shows zeolite holding metals with bactericidal properties such as silver, copper, and zinc, and (A) shows hollow fibers.
The required number of hollow fibers (A) in this example are formed into a ring shape so that the filtered water can be collected in the center.

含有率が多ければ、抗菌効果も良好となるが、中空糸の
成形上１％〜１０％の範囲が適当と考えられる。また、
ゼオライトの混入時期に当たっては、重合前のモノマー
に混合する方法から中空糸射出成形直前の原液に混合す
る方法まで任意の工程で混合が可能である。The above zeolite has an experimental specific surface area of 150 i/
It has been found that it is desirable to have a 5i02/A1.03 molar ratio of 14 or less, but the present invention is not limited to this, and natural or artificial materials may be used. As is well known, the content of zeolite in hollow fibers is 1% or more by weight, and generally speaking, the higher the content, the better the antibacterial effect. A range of 10% is considered appropriate. Also,
Regarding the timing of mixing zeolite, it can be mixed in any step, from mixing it with the monomer before polymerization to mixing it with the stock solution just before hollow fiber injection molding.
ただし混合は、原料モノマー時に実施した方が、ゼオラ
イトの分散には都合がよい。However, it is more convenient for dispersing the zeolite to mix the raw material monomers.
更に、上記ゼオライトの粒径をなるべく小さく（例えば
数ミクロン程度）に設定することは、特に有効であって
、殺菌、防カビ性を大幅に向上させることができる。そ
の理由は、ゼオライトの粒径が小さいほど比表面積が増
大することになり、中空系表面の処理水と接触させ得る
ゼオライト表面積が増大するため、抗菌性・殺菌性を有
する金属イオンを処理水に効率よく作用させることがで
きるからである。また、上記のようにゼオライトの粒径
を小さくすることは、ゼオライトの単位重量当たりの抗
菌性、殺菌性を高めるだけでなく、中空系成形時におけ

よい。Furthermore, it is particularly effective to set the particle size of the zeolite as small as possible (for example, on the order of several microns), and can significantly improve the bactericidal and antifungal properties. The reason for this is that the smaller the zeolite particle size, the larger the specific surface area, which increases the surface area of the zeolite that can be brought into contact with the treated water on the surface of the hollow system, which allows metal ions with antibacterial and bactericidal properties to be introduced into the treated water. This is because it can be made to act efficiently. In addition, reducing the particle size of zeolite as described above not only increases the antibacterial and bactericidal properties per unit weight of zeolite, but also helps to uniformly disperse the zeolite in the resin during hollow molding. convenient.

It can be provided safely without requiring any operations. In addition, it is expected to have the effect of preventing the deterioration of filtration performance due to the growth of bacteria and mold as described above.
