Abstract

FIBRES CREUSES15, PARTICULIEREMENT UTILES COMME MEMBRANES SEMI-PERMEABLES DANS DES DISPOSITIFS SEPARATEURS TELS QUE DES DIALYSEURS POUR HEMODIALYSE, AYANT UNE SURFACE DE SECTION NON UNIFORME SUR LEUR LONGUEUR. LES FIBRES ONT PERIODIQUEMENT DES POINTS DE DIAMETRE EXTERIEUR MAXIMAL20 ET DES POINTS DE DIAMETRE EXTERIEUR MINIMAL21 ET CES POINTS PEUVENT REVENIR REGULIEREMENT OU AU HASARD. LES EPAISSEURS DE PAROI18 DES FIBRES PEUVENT ETRE SENSIBLEMENT UNIFORMES OU NON UNIFORMES. L'INVENTION CONCERNE AUSSI DES PROCEDES ET APPAREILS POUR LA PRODUCTION DES FIBRES.
