Abstract

See full text

A multi-angle spinneret for forming hollow fibers is provided. The multi-angle spinneret includes a body defining a dope chamber, a bore needle channel, and multiple dope channels being oriented at a minimum of two distinct dope channel angles relative to the dope chamber. The body includes a bore needle disposed in the bore needle channel and oriented substantially perpendicular relative to the dope chamber. The bore needle extends though the dope chamber, such that a bore fluid flow through the bore needle is kept separate from a dope flow through the dope channels. A bore fluid outlet is positioned within a dope outlet of the dope chamber, such that a bore fluid flow out of the bore fluid outlet is substantially coaxial with and substantially centered within a dope flow out of the dope outlet.
