Abstract

A method of forming a plurality of hollow fibers includes the step of providing an elongated flexible substantially continuous fiber and coating an outer surface of the fiber with a hollow fiber material. The hollow fiber material is cured or hardened. A gap is created between the outer surface of the support fiber and the inner surface of the coating layer defined thereon. The coated support fiber is cut into a plurality of fiber segments each having exposed ends. The support fiber segments are removed from the coating layer so as to provide a plurality of hollow fibers.

Abstract

A method of forming hollow fiber bundles includes the step of providing a mat having a plurality of hollow fibers forming a weft and a plurality of soluble fibers forming a warp. Each hollow fiber extends between a first side and an opposed second side of the mat. The mat is bundled so as to form a bundle with the first side of the mat defining a first end of the bundle and the second side of the mat defining a second end of the bundle. At least a portion of the bundle is potted so as to substantially fix a position of the hollow fibers relative to each other. The soluble fibers are at least partially dissolved so as to remove the soluble fibers from the bundle.
