Abstract: Disclosed is the method for creating a reinforced hollow fiber membrane by applying reinforcing filaments to a core, casting a dope over the filaments and core, forming a membrane from the dope, and removing the core. The core may be a moving core, and the reinforcing yarns may comprise warp yarns and a spiral wrap yarn. The core may be soluble and removed by dissolving it. The core may be pre-wrapped with a yarn before the warp yarns are applied. The resulting reinforcing cage may be pre-shrunk before it is coated with a membrane dope. The pre-wrapped yarn may be removed, for example by dissolving it, after the reinforcing cage is coated. A precursor assembly for making a hollow fiber membrane is also provided.

Abstract: Various methods of making a reinforced membrane, devices for making the membranes, and the resulting membranes are described. The methods typically provide a reinforcing structure that includes filaments extending around the circumference of the membrane but without the filaments being part of a braided or woven structure. Some of the reinforcing structures also include longitudinal filaments. The methods and devices can be used to make a supporting structure in line with membrane formation steps, and also allow for a reinforced membrane to be produced that has a ratio of inside-to-outside diameters of 0.5 or more.
