Abstract

PURPOSE: To obtain hollow fibers having improved dialysis property, by extruding a cellulose ester solution in acetone into hollow fibers and a specific aliphatic or alicyclic hydrocarbon or both as a core component stably at a high speed.
CONSTITUTION: A cellulose ester is dissolved in an organic solvent consisting mainly of acetone, and extruded through an annular slit of a spinneret as a sheath component. A liquid consisting mainly of a≥6C aliphatic or alicyclic hydrocarbon or both as a core component are extruded through the central part of the extruded linear solution. Preferably, a space, 5cm or longer, is provided before the coagulation both. n-Hexane, tetralin, etc. may be used as the core component.
EFFECT: Well-balanced hollow fibers can be obtained without mixing of the sheath and core components.
USE: Vltrafiltration and blood dialysis.
