Abstract
A braid-reinforced hollow fiber membrane which includes a reinforcing material of a tubular braid and a polymer resinous thin film coated on the surface of the reinforcing material. The polymer resinous thin film has a skin layer with micro pores having a diameter in the range from 0.01 to 1 μm and an inner layer of a sponge structure with micro pores having a diameter less than 10 μm.The hollow fiber membrane exhibits excellent mechanical strength, reliable filtration and simultaneously, good water permeability.
