Abstract

Det er beskrevet en fremgangsmåte for fremstilling av celluloseformlge membraner l form av flatefoller, rørfoller eller hultråder med forbedret biokompatlbl- lltet ved anvendelse av bomullsflbrer, spesielt llnters, som er behandlet l alkalisk væske l en ett- trlnns fremgangsmåte med gassformlg, molekylært oksygen; videre er det beskrevet på denne måten oppredede bomullsflbrer, spesielt llnters. dermed fremstilte membraner samt deres anvendelse for hemodlalyse.
