いられる中空糸膜モジユールを製造するに適した
中空糸膜編物に関する。[Detailed description of the invention] [Industrial application field] The present invention is suitable for manufacturing hollow fiber membrane modules used in artificial lungs, artificial dialysis, plasma pheresis, pure water production, gas filtration/separation, water purifiers, etc. Concerning suitable hollow fiber membrane knitted fabrics.
一般に中空糸膜モジユールは中空糸束を所定の

開口状態にする方法が採用されている。
Generally, a hollow fiber membrane module is manufactured by cutting a bundle of hollow fibers to a predetermined length, storing the bundle in a container, and fixing the ends of the hollow fibers to the container with epoxy resin, urethane resin, or the like. However, if the opening at the end of the hollow fiber is fixed in an open state, the resin will enter through the opening, making it unusable as a module.To avoid this, the end of the hollow fiber bundle was temporarily sealed with resin, etc. A method is adopted in which the hollow fiber bundle is fixed in this state, and after fixing, the fixed portion is cut to open the ends of the hollow fiber bundle.

が不良の場合は一部の中空糸膜の開口部が固定用
樹脂により封鎖されるためモジユールに所定の膜
面積が確保できず、時にはせつかく製作したモジ
ユールを不良品として廃棄しなければならない。 In the conventional technology, there have been problems mainly with processing costs during temporary sealing during module production, reliability of the temporary sealing, disturbance of the hollow fiber bundle during fixing, and reliability of fixing. That is, although the temporary sealing part is a part that will be discarded when the module is completed, material costs and processing costs have to be spent on the temporary sealing process.
Furthermore, it is difficult to determine whether the temporary sealing is being performed without any problems at the time of the temporary sealing, and it is only possible to determine whether the temporary sealing is good or not by observing the cut surface of the fixed part after the module is manufactured. Furthermore, if this temporary sealing is defective, some of the openings of the hollow fiber membranes will be sealed with the fixing resin, making it impossible to secure the required membrane area for the module, and sometimes the module that has been painstakingly manufactured may be discarded as a defective product. There must be.
また、中空糸束を容器内に収納する方法をとる
ために中空糸束をきつちりそろえて容器内に収納
する必要があり、さもないと周辺部の中空糸が乱
れてその中空糸の端部が固定用樹脂内に埋没し、
その結果中空糸が有効に使用できなくなるという
欠点があつた。 In addition, in order to store the hollow fiber bundle in a container, it is necessary to arrange the hollow fiber bundle tightly and store it in the container, otherwise the peripheral hollow fibers will be disturbed and the ends of the hollow fibers will be disorganized. is buried in the fixing resin,
As a result, there was a drawback that the hollow fibers could not be used effectively.
また中空糸を束として使用するため中空糸が比
較的密に充填されることが多く、固定時において
中空糸束の中央部の中空糸間に固定用樹脂が進入
し難く、その結果、固定不良による不良品が発生
し易いという欠点があつた。 In addition, since hollow fibers are used as a bundle, the hollow fibers are often packed relatively densely, making it difficult for the fixing resin to enter between the hollow fibers in the center of the hollow fiber bundle during fixation, resulting in poor fixation. The disadvantage was that defective products were more likely to occur.
この様な現状に鑑み、本出願人は中空糸膜が切
断されることなく折り返され、両耳が通常糸でく
さり編でおさえられてなる編地を特願昭60−
199077号として提案した。 In view of this current situation, the present applicant filed a patent application in 1983 for a knitted fabric in which the hollow fiber membrane is folded back without being cut, and both sides are held together with regular threads.
Proposed as No. 199077.
この中空糸膜編物は中空糸膜面積が所定の値と
なるように所定のコース数のところで分割、切断

モジユールを形成すると、中空糸の開口端がポツ
テイング前は全体で２つしかなく、モジユール製
作時に中空糸仮固定の必要もなく、整然かつ確実
に固定するのが容易となる特徴を有している。 This hollow fiber membrane knitted fabric is divided and cut at a predetermined number of courses so that the hollow fiber membrane area becomes a predetermined value, and this is wound into a sushi roll shape, one end is potted, and then cut at the potted part. When a hollow fiber membrane module is formed, there are only two open ends of the hollow fibers in total before potting, and there is no need to temporarily fix the hollow fibers during module production, making it easy to fix them neatly and reliably. are doing.
しかし、このような中空糸膜編物は連続した編
地となつているので、所定のコース数（中空糸膜
が横方向に振られた回数）分で切断して所定の膜
面積のものとする必要がある。 However, since such a hollow fiber membrane knitted fabric is a continuous knitted fabric, it is cut after a predetermined number of courses (the number of times the hollow fiber membrane is swung in the horizontal direction) to obtain a predetermined membrane area. There is a need.
しかし編物の全体にわたつて中空糸膜が振られ
てその両端の耳部を経糸によるくさり編で保持さ
れたものでは中空糸膜が密に配置されているた
め、所定の切断部以外のところで中空糸膜を傷つ
ける場合が多い。 However, in knitted fabrics in which the hollow fiber membranes are swung over the entire length of the knitted fabric and the selvedges at both ends are held together by the warp threads, the hollow fiber membranes are densely arranged, so that hollow fibers are formed at areas other than the predetermined cut areas. It often damages the thread membrane.
又、これを切断してモジユールを形成する場
合、切断により生ずる中空糸膜開口端が同一の耳
部側にあるようにして、その耳部を固定しないと
リークの原因になるが、この判断も固難で切断場
所の選択と切断を人手で慎重に行なわねばなら
ず、工程機械化のネツクとなる。 Also, when cutting this to form a module, make sure that the open ends of the hollow fiber membranes created by cutting are on the same ear side and fix the ears, otherwise leaks may occur, but this judgment also applies. Due to the difficulty of cutting, the selection of the cutting location and cutting must be done carefully by hand, which is an obstacle to mechanizing the process.
さらに、切断箇所に近接したくさり編の部分に
も中空糸が編み込まれているので、その部分がほ
つれて形成される中空糸束にみだれが生じ易いと
いう問題がある。 Furthermore, since the hollow fibers are also woven into the part of the chain stitch close to the cutting point, there is a problem in that the hollow fiber bundle formed by fraying in that part is likely to become sagging.
本考案者らはこのような状況から上記問題を解
決すべく鋭意検討した結果、本考案に到達した。 In view of this situation, the inventors of the present invention have conducted intensive studies to solve the above-mentioned problems, and as a result, they have arrived at the present invention.

That is, the gist of the present invention is a warp knitted fabric using hollow fiber membranes as weft yarns, in which the hollow fiber membranes do not form loops and are swung over a predetermined width, and the warp yarns are interlocked at the edges of the knitted fabric. In the hollow fiber membrane knitted fabric in which the hollow fiber membrane is held by the method, the hollow fiber membrane runs along one end of the warp knitted fabric for a predetermined number of courses B for each predetermined number of courses A without being held by the chain knitting. A hollow fiber membrane knitted fabric characterized by:

場合は２〜32本であることが好ましい。 The hollow fiber membrane used in this invention separates and
This is a hollow fiber membrane used for gas-liquid contact, liquid-liquid contact, etc. Any hollow fiber membrane can be used as long as it can be folded back without causing crushing or damage at the edge. However, polyolefin hollow fiber membranes such as polypropylene and polyethylene are preferably used because of their flexibility.
The weft may be a monofilament of this hollow fiber membrane, or it may be a monofilament of a plurality of these. In the case of doubling yarns, the number of yarns is preferably 2 to 32.

的小さくすることが好ましい。 The warp in the knitted fabric can be any warp used in ordinary knitted fabrics or woven fabrics, but it is preferable that the warp is not hard so as not to damage the hollow fiber membrane during production or handling of the knitted fabric, and multifilament, Spun yarn or processed yarn is preferably used. It is also preferable that the tension during knitting and weaving be relatively small.
以下図面を用いて本考案を説明する。 The present invention will be explained below using the drawings.

An example is shown in which two chain stitches are provided in each section, but any number of stitches may be used as long as the shape of the knitted fabric can be maintained to the extent that there are no problems in handling, and there may be warp yarns in areas other than the selvedges. You may do so.

膜がふられずに走行する部分は必ず編織物の特定
の側の端を走行するものである。 In the hollow fiber membrane knitted fabric of the present invention, the hollow fiber membrane is swung from one end of the knitted fabric to the other end for a predetermined number of courses A, that is, a predetermined number of times, and is held by the warp yarns 2, 2', 3, and 3' in a chain stitch. The part where the hollow fiber membrane runs on one end of the knitted fabric without being shaken by a predetermined number of courses B are alternately provided, and the part where the hollow fiber membrane runs without being shaken. always runs along the edge of a particular side of the knitted fabric.

に設定される。 Although the number of courses A is shown as 4 in FIG. 1, this is for the purpose of simplifying the drawing, and the actual number is usually much larger than this. This knitted fabric is cut as shown at X-X' at a portion where the chain stitch is skipped by a predetermined number of courses B.
At this time, the hollow fiber membrane is necessarily cut along with the warps 2 and 2' of the normal yarn at the X side end, but only the warps 3 and 3' of the normal yarn are cut at the X' side end. Since this X-side end has a cutting opening for the hollow fiber membrane, the X-side end is necessarily set on the resin fixing side during the module manufacturing process.

ことがないので好ましい。 For this reason, if the colors of the warp yarns 2, 2' and 3, 3' are made different from each other when knitting the hollow fiber membrane knitted fabric, the operator can automatically judge the colored yarns on the end surface by visual inspection.
This is preferable because it allows you to choose the side to which the resin is fixed, so there is no chance of making any mistakes.

方の耳部側にくるようにするためにはコース数Ａ
を偶数にする。 When manufacturing the knitted fabric of the present invention in order to always make a module with a constant membrane area, the number of courses A should be the number of courses that corresponds to the membrane area.
When the knitted fabric is used to make a plurality of types of modules with different membrane areas, the number of courses may be determined to be close to the membrane area that is a common divisor. In short, the number of courses that is easy to create a module can be appropriately selected. However, in order to ensure that the open end of the hollow fiber membrane is always on one ear side when cutting, the number of courses is A.
Make it an even number.
コース数Ｂは編物の切断にあたつて容易に切断
