摘要：
Unstretched hollow fibers of cuprammonium celllulose for dialysis possessing a film structure having a porosity of 15 to 25%, a pore diameter of 25 to 40 A, and an ultrafiltration raio of 3.0 to 5.5 ml mmHg.hr.m 2 are obtained by extruding, coagulating, and regenerating a cuprammonium cellulose spinning dope having a cellulose concentration of 6.8 to 8.7% and a viscosity of 500 to 1,300 poises (at 20°C).
