Verfahren zur Färbung von im Nass-Spinnverfahren hergestellten Fasern

摘要

A process for the continual dyeing of fibres produced by a wet spinning process, in particular for the continual dyeing of polyacrylonitril tow in a hydrated condition is disclosed in that the fibre or the fibre strand after fibre formation without previous drying is passend through a dyestuff solution or suspension which is flowing in counter current. Said process is very economical and provides without the use of any electronic controls the continual dyeing of said fibres with almost 100 percent exhaustion.
