HOLLOW-FIBER MEMBRANE MODULE PROCESS FOR PRODUCING HOLLOW-FIBER MEMBRANE AND PROCESS FOR PRODUCING HOLLOW-FIBER MEMBRANE MODULE

摘要

(Problem) An object of the present invention is to provide a dry-type hollow fiber membrane module having excellent blood compatibility and less eluate, and a method of manufacturing a hollow fiber membrane and a hollow fiber membrane module embedded in the module. (Solution means) A hollow fiber membrane module comprising a hollow fiber membrane containing a hydrophobic polymer and a hydrophilic group-containing polymer and satisfying the following items. (a) the water content of the hollow fiber membrane is 10% by weight or less (b) the hydrophobic polymer does not contain nitrogen, the hydrophilic group-containing polymer contains nitrogen, and the nitrogen content of the hollow fiber membrane is 0.05% by weight or more 2.0 × 10 used for titration for the eluate of 0.4% or less (c) the film said hydrophilic group content of containing polymer with less than 45 wt% to 20 wt.% (d) priming final latex 10mL of the inner surface ^- Consumption of ³ mol/L potassium permanganate aqueous solution is 0.2mL or less per 1㎡ of membrane area
