Description
かかる多孔質中空糸膜は、1本の多孔質中空糸膜または複数本の多孔質中空糸膜を束ねたものについて、その外周表面が4本以上、好ましくは4〜8本の繊維状物によって編み組みされて編物状とされる。編み組みは基本的には丸打ち紐作製の要領にて行われる。繊維の本数がこれより少ないと、編み組みを行うことができず、また編み組が密に行われあるいは本数を多くすることで、空隙の割合がこれより少なくなってしまうと多孔質中空糸膜本来の性能、すなわち流体の透過性能が著しく低下してしまうため好ましくない。なお、編み組みする際の多孔質中空糸膜の本数は、多孔質中空糸膜の径や材質、あるいは用途によって適宜設定することができ、特に限定されるものではないが、より一層強度を向上させるといった観点からは、好ましくは複数本、例えば3本以上の多孔質中空糸膜束が用いられる。 Such a porous hollow fiber membrane is a bundle of one porous hollow fiber membrane or a plurality of porous hollow fiber membranes, and the outer peripheral surface thereof is 4 or more, preferably 4 to 8 fibrous materials. Braided into a knitted shape. The braiding is basically performed in the manner of making a round string. If the number of fibers is less than this, braiding cannot be performed, and if the braiding is performed densely or the number of fibers is increased, the percentage of voids becomes smaller than this, the porous hollow fiber membrane The original performance, that is, the permeation performance of the fluid is remarkably deteriorated. The number of porous hollow fiber membranes when braiding can be appropriately set depending on the diameter, material, or application of the porous hollow fiber membrane, and is not particularly limited, but further improves the strength. From the viewpoint of making them, a plurality of, for example, three or more porous hollow fiber membrane bundles are preferably used.
また、多孔質中空糸膜(束)外表面の繊維状物の存在は、多孔質中空糸膜束内を流れる流体の乱流を生じさせることも可能となり、これによって多孔質中空糸膜表面に絶えず新しい流体が接触するため、加湿用途の多孔質中空糸膜にあってはその加湿効率を高めることが可能となり、ろ過用途の多孔質中空糸膜の場合にもろ過効率を向上せしめることができるといった効果も奏する。 In addition, the presence of the fibrous material on the outer surface of the porous hollow fiber membrane (bundle) can also cause turbulence of the fluid flowing in the porous hollow fiber membrane bundle, and thereby the surface of the porous hollow fiber membrane is Since a new fluid is constantly in contact with the porous hollow fiber membrane for humidification, it is possible to increase the humidification efficiency, and the filtration efficiency can be improved even in the case of a porous hollow fiber membrane for filtration. There are also effects such as.
