Hollow fiber membrane and method for manufacturing hollow fiber membrane |
| abstract |
The hollow fiber membrane contains vinylidene fluoride resin and polyethylene glycol. The hollow fiber membrane contains 1.0 part by weight or more and less than 5.0 parts by weight of polyethylene glycol with respect to 100 parts by weight of vinylidene fluoride resin. In the radial direction of the cross section perpendicular to the longitudinal direction, the hollow fiber membrane is divided into three equal parts by drawing a line from the inner surface side to the outer surface side, and the polyethylene glycol standardized strength at each intermediate point is determined by the inner surface portion a and the center. When the portion b and the outer surface portion c are defined, c is less than 0.3 and a is 0.5 or more. |
