Verfahren zur Entfernung von Lumenfüllern und anderen löslichen Rückständen aus Hohlfäden

摘要

Described is a method and device for the removal of filling fluid and/or other soluble residues from the bore cavities of bundles of hollow fibres. The bundles of fibres are first precleaned by centrifuging and subsequently cleaned by spraying and centrifuging, preferably in a multi-stage procedure. The first spraying stage is preferably a single-pass operation, while subsequent stages are carried out in closed cycles. When the concentration of the impurities in the cleaning fluid has reached a constant level, the fluid is used for later cleaning stage. The fluid from the first spraying stage is fed to a reprocessing unit.
