摘要
A skinless hollow fiber of a cellulose ester material is formed by providing an aqueous coagulation bath having a tube-in-ring jet immersed therein and extruding a spinning solution comprising at least one cellulose ester material and a solvent therefor directly into the bath through an annulus surrounding the tube of said tube-in-ring jet while simultaneously allowing a portion of the liquid in the bath to be autogenously aspirated through an opening in the tube, located below the surface of the liquid in the bath, and through the tube thereby forming a lumen in the extruded fiber and then drying the extruded fiber.
