Beschreibung
Zusammenfassung:	Process for the space-dyeing of yarn or sliver made from cellulose fibers, wherein a wound package of the said textile material is first impregnated with an aqueous liquor containing an alkaline substance and at least one component capable of entering into azo coupling, and subsequently - at least at one selected portion of the bobbin - one or several weakly acid aqueous solutions each containing a mixture of at least two diazonium compounds of aromatic amines having different diffusibility are injected into the goods so treated for development of the azo dyestuffs.
