摘要： Disclosed is a porous membrane with high tensile strength, good elongation at break, and good water permeability, and a method for manufacturing the same. The porous membrane comprises a bead structure including plural spherical crystallites, wherein macro voids isolated from one another with the plural spherical crystallites are formed in an outer surface side of the porous membrane.

摘要： A tubular braid and a composite hollow fiber membrane using the same are disclosed. The tubular braid is made by braiding yarns, the yarn made by combining thin filament and thick filament, wherein the thin filament is comprised of a plurality of monofilament having a fineness of 0.01 to 0.4 denier, and the thick filament is comprised of at least one monofilament having a fineness of 3 to 50 denier. Also, the composite hollow fiber membrane using the tubular braid of the present invention can realize excellent water permeability, high mechanical strength, good filtration reliability, great peeling strength, low dope permeation, and high stiffness.
