Dual-layer ultrafiltration hollow fiber membrane and manufacturing method thereof |
| abstract |
The present invention relates to a porous inner supporting layer having macropores; And a porous outer selective layer having fine pores, and a method for producing the same. According to the present invention, by optimizing the composition and the spinning conditions of the inner and outer dope solutions, it is possible to produce a double-layer ultrafiltration hollow fiber membrane excellent in water permeability and removal rate without peeling between the inner support layer and the outer selection layer, It is possible to apply it to an industrial separation membrane. |
