Abstract
PURPOSE: A hollow fiber usable for hemodialysis, having a small membrane thickness, large inside diameter, and very few small macrovoids, obtained by dry-jet and wet spinning of a cellulose ester solution.
CONSTITUTION: A cellulose ester, e.g. cellulose acetate, is dissolved in a water- miscible organic solvent, e.g. formamide or acetone, and subjected to dry-jet and wet spinning with water as a coagulant into a hollow fiber having an inside diameter of 100W400μ, a membrane thickness of 5W25μ, and an apparent density of 0.6W1.2g/cm3. Preferably, a solvent for the ester, a swelling agent, e.g. dimethyl sulfoxide, an aqueous water-soluble salt, e.g. sodium chloride, or a specific liquid, e.g. monoterpene-containing one, may be used as a core liquid.
EFFECT: Improved spinnability, and good adjustment of thickness and outside and inside diameters to desired values.
