ABSTRACT:
A process for the subsequent dyeing of cellulose fibre materials with reactive dyestuffs by the exhaust method from a single bath is characterized in that the exhausted bath used for the previous dyeing is reused without any further purification operation after the volume, salt content and initial pH value have each been brought to the level required for the next dyeing.
