Evaluation of the intensifying effect of quaternary ammonium salts in the course of dyeing of cellulose materials with active dyes

Abstract

The effect of quaternary ammonium salts on batch dyeing of cellulose materials with active dyes was examined. The use of benzyldimethylhexadecylammonium chloride and benzyldimethyldodecylammonium bromide as intensifi ers in dyeing of cellulose textile materials with active dyes of vinyl sulfone and monochlorotriazine types allows high intensity and durability of the color to be attained owing to increased degree of covalent fi xation of the dyes and their decreased desorption in the course of washing of the dyed material.
