PROBLEM TO BE SOLVED: To provide a bundle attachment tube for a hollow thread membrane module and a method of manufacturing the same, for improving an adhesive property with an amine-curing system epoxy resin sealant.SOLUTION: The bundle attachment tube for the hollow thread membrane module is provided by introducing a sulfone group by applying acid treatment to a surface of the bundle attachment tube made of a polyether ether ketone resin or a polyphenylene sulfide resin. The bundle attachment tube of the hollow thread membrane module is manufactured by cleaning the bundle attachment tube made of the polyether ether ketone resin or the polyphenylene sulfide resin by pure water, after performing immersion treatment under a temperature condition of 50-80°C in a sulfuric acid with the concentration of 4-10 mole/L. |
