適応化が進められている。Reverse osmosis hollow fibers used for desalination and desalination of seawater, etc., and limited hollow fibers used for filtration separation of bacteria, virus proteins, colloidal substances, etc., are used in the food industry, pharmaceutical industry, electronic industry, etc. A wide range of adaptations are underway, including for pollution prevention.
＼中空繊維は膜状のものに比して単
位体積当りの１過面積が犬きぐなること、補強用の支持
体が不要であること等の大きな特徴を有しているが。\Hollow fibers have great features compared to membrane-like fibers, such as a smaller area per unit volume and no need for a reinforcing support.
般に繊維束として用いられる場合に末端のシール部分が
うまく行かず、繊維密度が低いとか、不完全シールによ
る漏れ、接着部分が広くなりそれだげ濾過面積が低下す
る等の問題が残っている。Generally, when used as a fiber bundle, the sealing part at the end does not work well, resulting in problems such as low fiber density, leakage due to incomplete sealing, and a wide bonded part, which reduces the filtration area. .
本考案者は以上のようなシール部分の問題点を解決する
と共に中空繊維を用いた濾過モジュールを容易に組立て
るための中空繊維集合体を提供するものである。The inventor of the present invention has provided a hollow fiber assembly that solves the above-mentioned problems with the seal portion and allows easy assembly of a filtration module using hollow fibers.
本考案は目的に応した長さにそろった中空繊維集合体が
少なくとも一方の末端部分が実質的に平行に並べられた
状態でテープ状の弾性体に埋め込まれ、中空繊維の中空
部分がの部に開放してなる中空繊維集合体である。In the present invention, hollow fiber aggregates having the same length according to the purpose are embedded in a tape-like elastic body with at least one end portion arranged substantially parallel to each other, and the hollow portion of the hollow fibers is It is a hollow fiber aggregate made of open fibers.
テープ状弾性体の材質としては中空繊維を損傷しない温
度で流動あるいは粘着、加硫できる弾性体であればどの
ような弾性体をも用いることができるが例えばシリコン
、ウレタン、各種ゴム、エポキシ等の弾性体を用いるこ
とができる。As for the material of the tape-shaped elastic body, any elastic body can be used as long as it can flow, stick, or be vulcanized at a temperature that does not damage the hollow fibers, such as silicone, urethane, various rubbers, epoxy, etc. An elastic body can be used.

樹脂等の液状接着剤を総枠に巻回した中空繊維束の一部
分に施与し、これを硬化させた後硬化部分を切断して中
空繊維の末端中空部分が開放された集合体を製造してい
る。Conventionally, when sealing the ends of a hollow fiber assembly, a liquid adhesive such as epoxy resin is applied to a part of the hollow fiber bundle wound around the whole frame, and after it is cured, the cured part is cut and the hollow fibers are sealed. An assembly with an open end hollow portion is manufactured.
このようにして製造された中空繊維集合体は末端部分の
形状が一定となるためモジュールの形状が固定されまた
高度の精度が必要となる。Since the hollow fiber aggregate manufactured in this manner has a constant shape at the end portion, the shape of the module is fixed and a high degree of precision is required.
一方１本考案の中空繊維集合体はモジュールの形状に従
って任意に容易に加工が出来る。On the other hand, the hollow fiber aggregate of the present invention can be easily processed arbitrarily according to the shape of the module.
ｆｌＪ、ｔば円筒型のモジュールの場合は、中空繊維集
合体の末端の弾性体のテープ状部分を渦巻状に張力をか
けて巻き込んで行けばよい。In the case of a cylindrical module, flJ, t may be wound by applying tension to the tape-shaped portion of the elastic body at the end of the hollow fiber assembly in a spiral shape.
この際巻量を加減することにより、所望のサイズの濾過
モジュールが得られ、各中空繊維が等間隔に配列され空
間を保持出来るのでｒ過動率が高い。At this time, by adjusting the amount of winding, a filtration module of a desired size can be obtained, and since the hollow fibers are arranged at equal intervals and spaces can be maintained, the r-passage rate is high.
モジュールの成形時には接着剤を併用することはさしつ
かえない。It is permissible to use an adhesive when molding the module.
このようにして成形したモジュールは中空繊維のシール
部分がテープ状の弾性体の巾できまり、シール部分の形
成による透過面積の減少を極力押えることか出来る。In the module molded in this manner, the sealing portion of the hollow fibers is closed by the width of the tape-like elastic body, making it possible to suppress the decrease in the permeation area due to the formation of the sealing portion as much as possible.
テープの巾及び厚さは取扱い時に繊維が簡単にばらけな
い程度に繊維を捕捉している必要があるが大きすぎると
モジュールを形成した時の膜面積の低下をもたらし好ま
しくない。The width and thickness of the tape must be such that it captures the fibers to the extent that they do not easily come apart during handling, but if they are too large, the membrane area will decrease when a module is formed, which is undesirable.
巾としては片側あたり繊維長の５〜１０％が好ましいが
、繊維長が充分長い場合は５〜４Ｑｌ！ｉｔ程度の巾が
あれば良い。The width is preferably 5 to 10% of the fiber length per side, but if the fiber length is long enough, it is 5 to 4 Ql! It is sufficient if it has a width of about 100 yen.
厚さとしては繊維列径の１．１〜２倍程度であることが
好ましい。The thickness is preferably about 1.1 to 2 times the fiber row diameter.
本考案を図を用いてさらに詳細に説明する。The present invention will be explained in more detail using figures.
中空繊維束の末端を従来法で行われているように樹脂で
固めてモジュールに加工する場合、接着剤樹脂２の粘度
が高いと中空繊維１の包埋がむづかしくシールが不完全
となり易く、一方粘度が低いと線維束の末端部分から中
心部へ接着部分が広がり第１図に示すような接着部分３
の中心部へ広がりが認められ有効膜面積を減少する。When the ends of the hollow fiber bundles are hardened with resin and processed into modules as is done in the conventional method, if the viscosity of the adhesive resin 2 is high, it is difficult to embed the hollow fibers 1 and the seal tends to be incomplete. On the other hand, when the viscosity is low, the adhesive part spreads from the ends of the fiber bundle to the center, forming an adhesive part 3 as shown in Figure 1.
Spreading toward the center of the membrane is observed, reducing the effective membrane area.
このような欠点は第２図に示す本考案の中空繊維集合体
によって解決される。These drawbacks are solved by the hollow fiber assembly of the present invention shown in FIG.
第２図において平面的に実質的に平行に引きそろえられ

態で中空繊維の末端が開放した状態となっている。In FIG. 2, hollow fibers 1 arranged substantially parallel to each other in a plane are embedded in a tape-shaped elastic body 4, with the ends of the hollow fibers being open.
該繊維集合体を円筒型状のモジュールに用いる場合には
、該繊維集合体を円筒型に巻込んで成形すると第３図に
示すように第１図の従来法によるものに比べて接着部分
の不要部分３がない。When the fiber aggregate is used in a cylindrical module, when the fiber aggregate is rolled into a cylindrical shape and molded, as shown in FIG. There is no unnecessary part 3.
この様な中空繊維集合体を形成する方法としては例えば
第５図に示すようにマンドレル５に中空線維を一層に巻
きつけ、そ（７）７ンドレルの一部６に常温硬化剤を混
合したポリウレタンを塗布し、中空糸を包埋した後硬化
させる。As a method of forming such a hollow fiber aggregate, for example, as shown in FIG. is applied and cured after embedding the hollow fibers.
硬化後第５図ＡＡ′の線に沿って切断することにより本
考案の中空繊維集合体が得られる。After curing, the hollow fiber assembly of the present invention is obtained by cutting along the line AA' in FIG.
マンドレルの大きさをかえれば該集合体の繊維長をかえ
ることができマンドレンに巻きつける密度。By changing the size of the mandrel, the fiber length of the aggregate can be changed, and the density at which the fibers are wound around the mandrel can be changed.
本数により、該集合体の繊維密度、本数を種々選ぶこと
ができる。Depending on the number of fibers, the fiber density and number of the aggregate can be variously selected.
マンドレルの代りにかせわくを用いることもできるし、
所定の長さに切りそろえた中空繊維を木枠に一時固定し
１両端を上記のように弾性体で包埋後両端包埋部で切断
してもよい。You can also use a skein instead of a mandrel,
Hollow fibers cut to a predetermined length may be temporarily fixed in a wooden frame, both ends of which are embedded in an elastic body as described above, and then cut at the embedding portions of both ends.
本考案の中空繊維集合体は中空繊維をきれいに平行に並
べることによって繊維密度を高めることにもなる。The hollow fiber aggregate of the present invention also increases fiber density by arranging the hollow fibers neatly in parallel.

合中空繊維の密度が高ぐ、平行性がよいので、実際の使
用にあたって透過効率が低下する恐れのある場合には、
第４図のように２枚の中空繊維集合体を斜向させて巻込
むことや。When forming the fiber aggregate into a module by winding, the density of the hollow fibers is high and the parallelism is good, so if there is a risk that the transmission efficiency will decrease in actual use,
As shown in Fig. 4, two hollow fiber aggregates are wound diagonally.
スペーサーを、−諸に巻込むことによって間隙を得るこ
とは容易である。It is easy to obtain a gap by wrapping the spacer around the ends.
又、中空繊維両端にあるテープ状の弾性体間に適当な間
隙で支持棒を設けておけば巻込んだ際の形態を安定化さ
せるのに有利である。Further, it is advantageous to provide a support rod with an appropriate gap between the tape-like elastic bodies at both ends of the hollow fiber to stabilize the shape when the hollow fiber is rolled up.
