Applications
Leveling for acrylic dyeing :
For acrylic dyeing, basic dyes, also called as cationic dyes are
used by exhaustion techniques. Basic dyes being cationic in nature,
it is advisable to use a leveling agent that will compete with it.
i.e it must be a cationic retarder rather than a leveling agent.
This is because, in addition to having an effect on the rate of
dyeing, cationic retarders also assist migration to an extent that
depends on the fiber and the substantivity of the dyes. They tend
to have higher diffusion rates than dyes and to be adsorbed at
lower temperatures (65-70°C)
Acrylic fibres vary significantly in the number of anionic sites
available for sorption of cations, but level dyeing accrues when
the number of cations in the system (retarder as well as dyes) is
just enough to saturate the anionic sites in the fibre. This means
more retarder will be needed for fibres of high saturation value
and for paler shades.
HONINGLITE™ CES due to its substantivity for acrylic fibres is most
suitable for dyeing of all types of acrylic fibres by any of the
normal methods. While HONINGLITE™ CES retards the build up of
cationic dyestuffs it does not block the fibre to any appreciable
extent, so the bath is well exhausted during the boiling process.
