ABSTRACT:
This invention relates to dyeing textile materials of polyacrylonitrile or copolymers containing acrylonitrile in polymerized form with basic dyestuffs in aqueous dyeing liquors using the exhaust method employing retarders. The retarders are obtained by condensing (a) piperazine and piperazine derivatives with (b) ethylene chloride, epihalohydrin, propylene chloride, 1,3-dichloro-2-hydroxypropane, bis-epoxybutane, 1,4-dichlorobutene or their mixtures in mole ratios of 1:0.9 to 1:1.1. The condensation products are then quaternized with benzyl chloride using 0.8 to 1.5 moles of benzyl chloride per mole of component (a) for the quaternization. The aqueous solutions of the retarders either do not foam or show a very low foaming tendency.
