This articles examines the production of thin-filament cellulosic (viscose) filament fibers for making a filter-material that can efficiently remove leukocytes from blood and its components. The main requirements for the fibers were formulated on the basis of preliminary studies. Equipment was chosen, an existing AVK-0.6 unit was rebuilt, and a process was developed for producing the fibers. The process includes the stages of fiber formation, regeneration, and washing. Processes were also developed for forming tows from the filament fibers and cutting the tows into fibers 4-6 mm long. The fibers have been used to create a filter-material for filtering leukocytes from blood and its components. © 2011 Springer Science+Business Media, Inc. Source
