PROBLEM TO BE SOLVED: To provide a moisture adjustment module with a function to humidify or dehumidify gas flowing through hollow fibers, a high airtight efficiency and manufacture easiness and to provide method and device for manufacturing this module.SOLUTION: The moisture adjustment module includes a tubular hollow fiber 1, a braiding thread 3 braided over the external side of the hollow fiber 1, and a tube 5 inserted into the end of a hollow fiber 1. The braiding thread 3 is deposited over the region in a range of a prescribed length from this end of hollow fiber 1 by heating both the follow fiber 1 and the braid thread 3 existing in the region at the temperature of 150 to 180°C from outside. At the same time, the hollow fiber 1 is fixed to the tube 5 through heat contraction.COPYRIGHT: (C)2011,JPO&INPIT【課題】中空糸内を流すガス中の水分を除湿または加湿する機能を有し、気密漏れが少なく製造の容易な調湿モジュール、該調湿モジュールの製造方法及び該調湿モジュールの製造装置を提供する。【解決手段】チューブ状の中空糸1と、この中空糸1の外側を編組状に編みこんだ編組糸3と、中空糸1の端部の内側に挿入された管5とを備え、この端部から所定長分の領域に存する中空糸1及び編組糸3について外部から150℃~180℃の温度で加熱をすることで、編組糸3を溶着し、同時に中空糸1を管5に対し熱収縮により固定する。【選択図】図2
