Abstract
PURPOSE: To obtain a product of a circular or nearlly circular sectional area, a thin and uniform thickness, and excellent dialysability by using as a core liquid a solvent and/or a swelling agent for polymer in the spinning of halogenated vinyl polymer by a holow fiber spinning method.
CONSTITUTION: A spinning liquid prepared by dissolving a halogenated vinyl polymer, e.g., PVC, etc., in a solvent, e.g., N,N'-dimethylformamide, etc., is extruded into a cottony state through an annular slit, and at the same time a liquid compatible with the spinning liquid but incapable of coagulating the polymer is introduced into the hollow portion inside the cottony substance. The liquid used in this way is cyclohexanone, dimethylsolfoxide, etc., or a mixture of these, or a mixture of these liquids with a miscible solvent. In this way, after spinning by a dry and wet type or a wet type method, it is introduced into a coagulating bath composed primarily of water to cause rapid coagulation to take place and then rolled up through a water-washing bath.
