摘要:
Dyestuff mixtures of at least two different dyestuffs of the general formula ##SPC1##In whichX = cn, no.sub.2 or alkylsulphonylY = hydrogen, methyl, ethoxy or methoxyR.sub.1 = hydrogen or alkylR.sub.2 = c.sub.1 -c.sub.4 -alkyl or an optionally substituted phenyl radical or phenylalkyl radicalAc = acyl.Using these mixtures for dyeing of polyester fibres deep clear blue dyeings with good general fastness properties are obtained.

摘要:
A process for printing and continuous fixation of stabilized dyeing preparations forming azo dyestuffs and of reactive dyestuffs on textile materials containing cellulose or consisting exclusively of cellulose material, comprising a continuous working process of steaming the material printed with the dyeing preparations and reactive dyestuffs, for a short time for developing and fixing the azo dyestuffs using high concentrations of volatile acids with or without use of a counter-current operation method, and of treating then the material according to a known two-phase-fixation process for fixing the reactive dyestuffs and finishing it as usual by washing, soaping and rinsing as well as a process comprising the said very rapid fixation process of stabilized dyeing preparations forming azo dystuffs, by means of acid steam except for the use of reactive dyestuffs and for the use of the two-phase-fixation process which leads to dyeings of azo dyestuffs and of reactive dyestuffs of good fastenesses and brilliancy obtained in a very short time by means of a fully continuous process of fixing azo and reactive dyestuffs and of after-treatment the dyed material.

LINEAR POLYESTER FIBERS DYED AND PROCESS FOR DYEING OR PRINTING LINEAR POLYESTER FIBERS WITH A WATER INSOLUBLE AZO DYESTUFF OF THE FORMULA
A-N=N-B-N(-R1)-R2
IN WHICH A REPRESENTS A THIAZOLE, BENZTHIAZOLE OR THIADIAZOLE RADICAL BOUND IN THE 2-POSITION TO THE AZO GROUP OR A BENZENE RADICAL WHICH MBY BE SUBSTITUTED, R1 DENOTES AN ALKYL GROUP WHICH MAY BE SUBSTITUTED AND R2 DENOTES A RESIDUE OF THE FORMULA-ALKYLENE-OCOR3, IN WHICH R3 REPRESENTS A RESIDUE WHICH CONTAINS A NITROGEN-CONTAINING 6-MEMBERED RING.
