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.

Successive dyeing with reactive dyestuffs of cellulose from standing

The present invention relates to a new dyeing process based on the exhaustion principle. It is characterized in that dyeing liquors are used which, in addition to the dyestuff or dyestuff mixture, contain one or more salts, at least one compound having a glycidyl radical and, if appropriate, further auxiliaries.

Dyeing process with reactive dyes and glycidyl compound

The present invention relates to a new process for dyeing or printing fibre materials with reactive dyestuffs which split off fluoride ions, which is characterized in that neutral or acid dyebaths or printing pastes which contain, in addition to the reactive dyestuff and customary auxiliaries and solvents, one or more organic and/or inorganic calcium compounds are employed.

Dyeing process and printing process using reactive dyestuffs

Process for dyeing cellulose fibres and textile materials containing cellulose fibres with water-soluble reactive dyestuffs by the exhaustion method, characterized in that it is carried out using dye liquors, the particular fibre-reactive reactive dyestuff content of which is less than 10% of the total content of fixed dyestuff in the end dyeing.

Process for dyeing cellulose materials with reactive dyestuffs by the

The present invention relates to a new process for dyeing cellulose fibres and fibre mixtures containing cellulose fibres, which is characterized in that at least two different reactive dyestuffs which give dyeings of the same color shade on cellulose and which have reactivities which differ from each other by a factor of at least 10, are used in the same dyebath.
