Verfahren zur Erzeugung von einer Beschichtung auf einer Hohlfaser

摘要

The invention relates to a method for generation of a coating on a hollow fibre, which has a porous embodiment. Said method is characterised in that the hollow fibre (11) is separated from the coating bath (12) at both sides by seals (18, 15). By applying a vacuum to a pressure connector (19), the movement of the coating bath through the pores (20), following the arrows drawn therethrough, is induced such that coatings (21) with high reproducibility can be produced in a short time. A distinct advantage of the invention lies in the possibility of simultaneously providing a number of fibres with a high quality coating.
