The colorant is extracted from the headspace fiber using suitable solvents under reflux, chlorobenzene is used as an example for polyester fibers. The extract is concentrated, transferred with methanol, taken up. It is treated in an ultrasonic bath to disperse the aqueous citrate-buffer solution and colorant.

Amines formed by adding sodium dithionite are transferred to a t-butyl methyl ether phase by liquid-liquid extraction using diatomaceous earth columns. The extract is concentrated and the residue is taken up in the container.

After the reaction solution has been in the diatomaceous earth column for the specified time, the residues of this reaction solution are quantitatively transferred from the reaction vessel to the diatomaceous earth column with the first 40 ml portion of t-butyl methyl ether from the reaction vessel.
