HOLLOW-FIBER MEMBRANE MODULE, METHOD FOR PRODUCING HOLLOW FIBER MEMBRANE, AND METHOD FOR PRODUCING HOLLOW FIBER MEMBRANE MODULE |
摘要 |
[Problem] To provide a dry-type hollow-fiber membrane module which has excellent blood compatibility and less releases a component therefrom, the hollow-fiber membranes which have been built into the module, and a process for producing the hollow-fiber membrane module. [Solution] A hollow-fiber membrane module having built-in hollow-fiber membranes which comprise a hydrophobic polymer and a hydrophilic-group-containing polymer, characterized by satisfying the following items. (a) The hollow-fiber membranes have a water content of 10 wt% or less relative to the weight thereof (b) The hydrophobic polymer contains no nitrogen, the hydrophilic-group-containing polymer contains nitrogen, and the hollow-fiber membranes have a nitrogen content of 0.05-0.4 wt% (c) The content of the hydrophilic-group-containing polymer in the inner surface of each membrane is 20-45 wt% (d) The amount of 2.0×10-3 mol/L aqueous potassium permanganate solution for titration consumed by the substances dissolved in 10 mL of a final priming liquid is 0.2 mL or less per m2 of the membrane area |
