Abstract
a. Procédé de fabrication de fibre creuse, comportant l'extrusion d'une solution de filetage d'un composé à haut poids moléculaire, par une fente annulaire. b. Procéde caractérisé en ce que, simultanément à l'extrusion de la solution de filage, un liquide de noyau, comprenant au moins un solvant du composé à haut poids moléculaire, et un liquide gonflant capable de gonfler le composé à haut poids moléculaire est extrudé à travers l'orifice entouré par la fente annulaire. c. Procédé applicable à la fabrication de fibres creuses à perméabilité sélective.
