    Abstract: Disclosed is a pressurized hollow fiber membrane module that exhibits improved durability without deterioration in packing density and permeation flux. The pressurized hollow fiber membrane module includes a composite hollow fiber membrane comprising a tubular braid woven by yarns and a polymer film on the outer surface of the tubular braid. At least one of the yarns comprises a small-fineness filament and a medium-fineness filament. The small-fineness filament comprises first monofilaments having a fineness of 0.01 to 0.4 denier, the medium-fineness filament comprises second monofilaments having a fineness higher than 0.4 and lower than 3, and a ratio of thickness of the tubular braid to outer diameter thereof is 15 to 35%.
