。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for manufacturing a hollow fiber membrane module used, for example, in household water purifiers, ultrafiltration membranes for medical use, and the like.
（従来の技術）

０２Ａを束ねて構成される中空糸膜１０２を挿入し、こ
の中空糸膜１０２の両端を充填接着剤１０３にて固定し
ている。そして、液体は中空糸膜１０２を通して濾過さ

部１０４か必要である。(Prior Art) A conventional hollow fiber membrane module of this type has a large number of hollow fibers 1 in a cylindrical case 101, as shown in FIG.
A hollow fiber membrane 102 formed by bundling 02A is inserted, and both ends of the hollow fiber membrane 102 are fixed with a filling adhesive 103. The liquid is then filtered through the hollow fiber membrane 102, and the filtrate flows out from the end face of the hollow fiber membrane 102. In order for this hollow fiber membrane module to function properly, an opening 104 is required at each end of the hollow fiber 102A of the hollow fiber membrane 102, as shown in FIG.
そのために、従来から第８図乃至第１ｏ図に示すように

保していた。For this purpose, conventionally, as shown in FIGS. 8 to 1o, a bundle of multiple hollow fibers 102A is inserted into a cylinder 101, both ends are cut, and then adhesive is applied to the end surface of the hollow fiber membrane 102. After sealing 105 and drying and solidifying as shown in FIG. 11, a filling adhesive 103 for fixing is injected into the membrane module manufacturing apparatus 107 as shown in FIG. The opening 104 of each hollow fiber 102A was secured by filling the fixing portion with the filler and finally cutting the filler 105 along the A-A plane as shown in FIG.
（発明が解決しようとする課題）
しかしながら、上記した従来技術の場合には、充填接着
剤１０３の充填前に別種の接着剤を用いて目止め１０５
をする必要があり、この目止め作業が生産性向上を阻害
する要因となっていた。(Problem to be Solved by the Invention) However, in the case of the above-mentioned prior art, a different type of adhesive is used to seal the filler 105 before filling the filler adhesive 103.
This sealing work was a factor that hindered productivity improvement.
すなわち、目止め１０５用の接着剤は毛細管現象て中空
糸１０２Ａの開口部１０４内に入っていかないように粘
度が高いものを用いる必要があるのに対し、充填固定用
の接着剤１０３は粘度が高いと中空糸１０１Ａ間に接着
剤１０３が入っていかず接着不良が発生ずるために粘度
が低いものを用いる必要がある。In other words, the adhesive for sealing 105 must have a high viscosity so that it does not enter the opening 104 of hollow fiber 102A due to capillary action, whereas the adhesive 103 for filling and fixing must have a high viscosity. If the viscosity is too high, the adhesive 103 will not enter between the hollow fibers 101A, resulting in poor adhesion, so it is necessary to use one with a low viscosity.
