    • A process for potting hollow fibers within a body is disclosed wherein a bundle of hollow fibers is formed within a hollowed portion of the body such that the fibers are substantially aligned and uniformly spaced. A molten thermoplastic composition is dispensed into the body at a contact temperature below the melting point of the hollow fibers. The bundle and the body are both at a temperature which is sufficiently low enough to cause solidification of the molten composition substantially upon contact with the bundle. A pressure differential is applied to the body to assist the flow of the thermoplastic composition around each of the hollow fiber elements such that the bundle and the interior of the hollowed portion of the body are encapsulated by the thermoplastic composition thereby assuring reliable sealing between the hollow fiber elements and the interior of the hollowed portion of the body.
    • 公开了一种在体内灌封空心纤维的方法,其中一束中空纤维形成在主体的中空部分内,使得纤维基本上对齐并均匀间隔开。 在低于中空纤维的熔点的接触温度下将熔融的热塑性组合物分配到体内。 束和体都处于足够低的温度,以使熔融组合物基本上与束接触时固化。 压力差被施加到身体以帮助热塑性组合物围绕每个中空纤维元件的流动,使得束体和身体的中空部分的内部被热塑性组合物包封,从而确保中空部件之间的可靠密封 纤维元件和身体的中空部分的内部。
