Definitions

• polyacrylonitrile fibers are dyed in general utilizing cationic dyes such as those for example of the series of triaryl methane, oxazine, etc.
• the application of cationic dyes onto the polyacrylonitrile fibers can be accomplished by different dyeing processes.
• the bath dyeing that is by exhausting dye baths, the taking up and the fixation of the dye into the fiber can be correctly obtained only at temperatures less than those in the vicinity of the boiling point of water.
• the present invention more particularly relates to the use of new retarding agents in the dye baths with the cationic dyes.
• FORMULA I in which R, R and R' are alkyl radicals, identical or FORMULA ll H N- R-Nm H in which at is at least equal to one;
• R is an alkylene radical having one to five carbon atoms, such as ethylene, propylene, butylene, etc.
• polyamines should in addition contain at least four atoms of reactive hydrogenper molecule as, for example, ethylene diamine (E.D.A. diethylene triamine (D.E.T.A.), triethylene tetramine (T.E.T.A.), etc.

• the proportion of dyeing bath was from one to twenty (that is, 20 ml of bath per i g. of material to be dyed).
• the temperature was brought in 30 minutes to 100C, then the dyeing was maintained at this temperature for an hour. After-this period, the bath was practically exhausted.
• the sample wasthen subjected to a rinsing and then a drying.
• the polyamino amide utilized in the example was obi tained' by condensation of a fatty diacid (EMPOL 1024) with ethylene diamine, followed by quatemization by the .chloride of epoxypropyltrimethyl ammonium.
