Abstract

PURPOSE: To obtain a hollow cellulosic fiber having a protrusion partially on the periphery thereof and improved dialytic properties, by extruding a spinning solution through an annular spinning hole into the lower layer in a two-layered bath consisting of a coagulating liquid in the upper layer and a noncoagulating liquid in the lower layer, and passing the extruded solution through the interface between both layers.
CONSTITUTION: A cuprammonium cellulosic spinning solution is extruded through an annular spinning hole of a spinneret 5 while introducing a noncoagulating liquid into the interior thereof, and coagulated and regenerated. In the process, the solution 6 extruded through the spinning hole is introduced into the lower layer 2 of a noncoagulating liquid, e.g. silicone oil, having a higher specific gravity than a coagulating liquid in a two-layered bath consisting of the lower layer 2 the coagulating liquid for the spinning solution, and e.g. 8W25% aqueous solution of sulfuric acid, in the upper layer 3, passed through the interface 7 between both layers, coagulated and regenerated. The specific gravity of the linear (filamentary) spinning solution 6, extruded through the spinning hole, and containing the noncoagulating liquid therein is preferably lower than that of the noncoagulating liquid in the lower layer 2.
