Abstract

Des fibres creuses non étirées de cellulose cuprammonique pour dialyse ont une structure en film ayant une porosité de 15 à 25 %, un diamètre des pores de 25 à 40 A et un débit d'ultrafiltration de 3,0 à 5,5 ml/mm Hg.h.m2 et sont obtenues par extrusion (6), coagulation (14) et régénération (16) d'une solution de filage de cellulose cuprammonique ayant une concentration en cellulose de 6,0 à 8,7% et une viscosité de 500 à 1300 poises à 20 degrés C. Ces fibres creuses conviennent spécialement pour fabriquer des reins artificiels.
