The intensifying effect of quaternary ammonium
salts (QASs) was revealed for the ﬁ rst time in dyeing
of polyester ﬁ ber textile materials with dispersible
dyes [1, 2]. Attainment of intense and durable colors
on hydrophobic ﬁ ber-forming polymers with low water
absorption involves certain problems and requires using
In coloring of materials based on hydrophilic
cellulose ﬁ bers exhibiting high sorption ability, the
problem of intensiﬁ cation is less acute, but it becomes
topical when water-soluble active dyes are used. This
is associated with the need to enhance the degree of
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.
covalent ﬁ xation of the dye on the ﬁ ber, so as to decrease
the dye desorption in washing of the dyed material and
thus to reduce the wastewater pollution.
This study deals with the intensifying effect of QASs
on batch dyeing of a cellulose material with active dyes.
Samples of cotton ﬁ ber, prepared for the full dye-
ing cycle (washing, cooking, mercerization, bleaching),
were dyed in the batch mode with active dyes of mono-
chlorotriazine (MCT, I) and vinyl sulfone (VS, II) types:
