Abstract
A hollow fiber bundle in which the hollow fibers are in the form of warp threads of woven hollow fiber tapes. The plurality of hollow fibers are held together by a low density, double weft thread. The hollow fiber bundles may form an angle with the lengthwise axis of the bundle such that adjacent woven hollow fiber tapes form an angle of intersection with one another or alternatively, the hollow fiber tapes may be made into partial bundles and the partial bundles assembled together so that the hollow fibers are arranged essentially parallel to one another and the lengthwise axis of the bundle. In both cases, the presence of weft threads ensures that the hollow fibers will not slide into the spaces between adjacent hollow fibers.
