PURPOSE: A tubular knitted fabric and a composite hollow fiber membrane using the same are provided to offer mechanical strength, especially excellent peel strength and low dope penetrability, and to hold a high stiffness feature. CONSTITUTION: As to the tubular knitted fabric, multifilament, in which yarns of twist structure are plaited, and multifilament in which triangle structure yarns are plaited, are mixed. A material of the tubular knitted fabric(1) is selected from a group consisting of polyethylene terephthalate and nylon. A distance, in which a polymer resin thin film(2) penetrates within the tubular knitted fabric is a 10 - 30% range of a thickness of the tubular knitted fabric. A fineness of the multifilament is 5 - 1500 denier. |
