Composite hollow fiber membrane and method of manufacturing composite hollow fiber membrane |
| abstract |
An object of the present invention is to provide a composite hollow fiber membrane which can be suitably separated by a semipermeable membrane layer, and a method for producing the composite hollow fiber membrane. A crosslinked polyamide comprising a semipermeable membrane layer 13 and a hollow fiber porous support layer 12, wherein the semipermeable membrane layer 13 is formed by polymerizing a polyfunctional amine compound and a polyfunctional acid halide compound. And the support layer 12 has a sloped structure in which the pores of the support layer 12 gradually increase from one of the inner surface and the outer surface to the other, and the support layer 12 contains the hydrophilic resin. The semipermeable membrane layer 13 is in contact with the dense surface 14 where the pores are small among the inner surface and the outer surface of the support layer 12 in which the entire layer 12 is hydrophilized, and the film thickness is It is the composite hollow fiber membrane 11 which is 0.02 to 0.3 mm.
