Abstract
A tubular braid, a hollow fiber membrane using the same, and a manufacturing method thereof. A hollow fiber membrane can maximize or increase adhesion between a polymer coating film and a tubular braid; significantly reduce degradation of film properties caused by non-uniform coating, that is, reduce leakage; obtain a higher percent rejection; and achieve high water permeability since the hollow fiber membrane has a larger inner diameter.
