| titleOfInvention | Process for dyeing polyacrylonitrile fibres |
| abstract | A process for dyeing polyacrylonitrile fibre material to obtain level dyeings of good penetration and excellent fastness properties consists in dyeing the fibre material with an aqueous dyebath which contains at least one migrating cationic dye and at least one quaternary compound of the formula <IMAGE> wherein R is an aliphatic hydrocarbon radical containing 6 to 22 carbon atoms or a cycloaliphatic radical of 5 to 12 carbon atoms, each of X1 and X2 is methyl or ethyl or together with the nitrogen atom to which they are attached are a 5- to 6-membered saturated heterocyclic radical, X3 is lower alkyl, hydroxy-lower alkyl or cyano- lower alkyl, and An<(-)> is an anion of an organic or inorganic acid. |
