| titleOfInvention | Hollow fiber composite membrane module and method for producing same |
| abstract | Provided is a method for producing a hollow fiber composite membrane module having high selective permeability and a high specific surface are ratio, whereby it becomes possible to prevent the deterioration of separation layers caused by friction generated upon the insertion of the module into a housing and also prevent the deterioration in performance resulting from the deterioration of the separation layers. The production method according to the present invention comprises the steps of: (i) producing a hollow fiber membrane having, on the outer surface thereof, a first separation layer made from a polymer having an anionic functional group; (ii) winding up the hollow fiber membrane to produce a fiber bundle; (iii) inserting the fiber bundle of the hollow fiber membrane into a housing; (iv) bonding at least one end of the fiber bundle of the hollow fiber membrane with a resin and performing an opening processing; (v) bringing the outer surface of the hollow fiber membrane into contact with an aqueous solution of a modified polyvinyl alcohol having at least one cationic or anionic functional group to form a second separation layer composed of an absorption layer made from the modified polyvinyl alcohol; and (vi) bringing the second separation layer into contact with an aqueous solution of an aldehyde compound to acetalize some of hydroxyl groups in the modified polyvinyl alcohol. |
