摘要: [Problem] The purpose of the present invention is to provide a polyamide hollow fiber membrane having such properties that transmission fine particles through can be prevented effectively, has an excellent water transmissibility, entire surface hydrophilicity, and impurities as metal elements are rarely eluted membrane. [Solution] A produced by TIPS method under specific production conditions following characteristic properties: (1) contact angle on 80° or less; (2) external pressure transmissibility 50 L/(m 2 ·atm·h) more; (3) nm-particles blocking ratio 90% more.
