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, resin will enter through the opening and the membrane module will become unusable.To avoid this, the end of the hollow fiber bundle must be temporarily sealed with resin, etc. A method is adopted in which the hollow fiber bundle is fixed in a fixed state, and after fixing, the fixed portion is cut to open the ends of the hollow fiber bundle.

In the conventional technology, the processing cost for temporary sealing during membrane module production, the reliability of the temporary sealing,
There were problems with the disorder of the hollow fiber bundle during fixation and the reliability of fixation. That is, although the temporary sealing portion is a portion to be discarded when the membrane module is completed, material costs and processing costs must be incurred in the temporary sealing process. Furthermore, it is difficult to determine whether this temporary sealing is being performed without any problems at the time of temporary sealing, and it is only possible to determine whether the temporary sealing is good or not by observing the cut surface of the fixing part after the membrane 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 membrane module, and sometimes the membrane modules that have been painstakingly manufactured may be rejected as defective products. must be disposed of.
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
中空束の中央部の中空糸間に固定用樹脂が侵入し
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 the hollow fibers are used as a bundle, the hollow fibers are often packed relatively densely, making it difficult for the fixing resin to penetrate between the hollow fibers in the center of the hollow bundle during fixation, resulting in poor fixation. The drawback was that defective products were likely to occur.

る。 In addition, a sagging-like fabric using a porous hollow fiber membrane has been proposed in Japanese Patent Application Laid-Open No. 60-28806 as a material that can uniformly fill the hollow fiber membrane.
In such textiles, hollow fiber membranes (wefts) are formed by warp yarns.
Since the restraint is insufficient, a reinforcing process such as pasting adhesive tape on both sides to the warp zone is indispensable, and it is difficult to process the membrane module after such troublesome post-processing. It is being done.
本発明者等はこのような現状に鑑み、上記欠点

ジユールにある。 That is, the gist of the present invention is to provide a hollow fiber membrane that is folded back to a predetermined width without being cut at the ears, and a hollow fiber membrane that is arranged at least in the vicinity of both ears of the hollow fiber membrane in a direction substantially perpendicular to the hollow fiber membrane. A hollow fiber membrane sheet consisting of a fibrous material, in which the fibrous material is knitted in a chain-knitted manner against the hollow fiber membrane by a warp knitting machine, is bundled, one end is fixed with a resin, and the end surface fixed with the resin is cut. A filtration module for a water purifier is obtained by forming an open end.

い。 The fibrous material used in the sheet-like product can be anything that is used for the warps and wefts of ordinary knitted or woven fabrics, but fibrous materials are used in order to avoid damaging the hollow fiber membrane during manufacturing and handling of the sheet-like product. It is preferable that the material is not hard, and multifilament, spun yarn, processed yarn, etc. are preferably used. It is also preferable that the tension during knitting be relatively small.
以下に本発明を図面を用いて説明する。 The present invention will be explained below using the drawings.

る。 Figures 1 to 3 are examples of hollow fiber membrane sheets used in the filtration module for water purifiers of the present invention.
In the figure, hollow fiber membranes 1 are mutually constrained by fibrous materials 2 forming a mesh structure arranged at both ears to form a sheet-like shape. The number of fibrous materials 2 placed on one ear is not particularly limited, but is usually 1.
It is sufficient to have about 4 to 4 fibers, and if the folding width of the hollow fiber membrane is large, a fibrous material 3 forming a mesh structure may be arranged in the intermediate portion as necessary.

があるかのようにリークを生じ問題になる。 As will be described later, the width of the sheet-like material approximately corresponds to the length of the membrane module, so the width of the sheet-like material is set in accordance with the size of the membrane module to be manufactured. Note that the end portions of the first and last hollow fiber membranes in the hollow fiber membrane sheet must be sealed in advance. If it remains open, when creating the membrane module after this, it is necessary to make sure that it is in the part that should be fixed with resin at one end of the membrane module, otherwise there will be a pinhole when using it. This can cause leaks and become a problem.

A book obtained by bundling hollow fiber membrane sheets in which the hollow fiber membranes are folded back without being cut at the ears, fixing one end with a resin, and then cutting the resin-fixed end surface to form an open end. By using the filtration module for water purifiers of the invention, the step of temporarily sealing the end face of the hollow fiber membrane, which was conventionally required when manufacturing the membrane module, becomes unnecessary, and the hollow fiber membrane bundle can be fixed neatly and reliably without disturbing it. becomes possible. In addition, at the start of filtration module production, both ends of the hollow fiber membrane sheet are tightly bound by fibrous material forming a mesh structure, making it easy to handle, and it is possible to immediately process the membrane module as is. There are also advantages such as diversification of membrane module shapes.

ることを可能とする。 Further, when the hollow fiber membrane sheet according to the present invention is used, conventional dyeing and finishing machines can be used and post-treatment can be carried out efficiently. For example, in order to use a hydrophobic hollow fiber membrane for a water purifier, post-treatment with a hydrophilic agent (hydrophilic treatment) is required, but conventionally, after fixing the hollow fiber membrane in a container, a hydrophilic agent solution is poured in. Since the product was made by drying, uniform processing was difficult due to migration during drying. On the other hand, the hollow fiber membrane sheet used in the present invention is in the state of the hollow fiber membrane sheet before being fixed to the container.
For example, processing in conventional beam dyers and hot air dryers is possible. That is, by using the hollow fiber membrane sheet according to the present invention as a starting material, it is possible to convert the conventional manual manufacturing process of membrane modules into a rational mass production process. Therefore, the filtration module for water purifiers of the present invention makes it possible to provide filtered water for drinking, cooking, hand washing in hospitals, etc. at low cost.
