Abstract
PURPOSE: To obtain a product of a circular or nearly circular sectional area throughout the whole length, a thin and uniform thickness, and excellent dialysability by specifically designating the composition of core liquid and coagulating bath for the hollow fiber solution spinning method of acrylonitrile polymer.
CONSTITUTION: A spinning liquid prepared by disssolving polyacrylonitrile polymer or a 60% or more acrylonitrile copolymer in N,N'-dimethylformamide, etc., is extruded into a cottony state through an annular slit, and at the same time dimethylsulfoxide or a muxture of dimethylsulfoxide and at least one selected from water ethanol, propanol, and glycerine, in a proportion of less than 30 wt%, is introduced into hollow portion inside the cottony substance. Then the cottony substance is introduced into a coagulating bath composed primarily of water or a liquid containing more than 40 wt% water to cause rapid coagulation to take place, and then introduced into a water-washing process for completion of coagulation.
