DYEING POLYACRYLONITRILE WITH BASIC DYESTUFF AND ALKOXYMETHYL QUATERNARY AMMONIUM COMPOUNDS

Fibrous material consisting at least predominantly of polyacrylonitrile is dyed in an aqueous dyebath containing a basic dyestuff and up to about 10 percent by weight of at least one alkoxymethyl quaternary ammonium compound as a decomposable retarder. An illustrative example of such a retarder is n...

Zusammenfassung:	Fibrous material consisting at least predominantly of polyacrylonitrile is dyed in an aqueous dyebath containing a basic dyestuff and up to about 10 percent by weight of at least one alkoxymethyl quaternary ammonium compound as a decomposable retarder. An illustrative example of such a retarder is n-tetradecyloxymethyltributylammonium chloride.
