Dyeing Methods and Dye Selection for Blends of:
Cationic Dyeable – PES Fibers
Cationic dyeable PES / CV is dyeable with same process
as PAC / CV
I – One Bath Method with Cationic/
Indosol Dyes
This method is only recommended for pastel and
medium shades.
Thiotan R paste prevents precipitation between
the cationic dyes and anionic Indosol dyes, which
may occur depending on the dyes and concentrations
used.
Standard Recipe
It is essential to set the dye bath in the following
order:
Liquor ratio: 1/10
a) 1 g/l Thiotan R paste
0.5 g/l sodium acetate
Run 5 – 10 min
b) x % Cationic dye
Run 5 – 10 min
c) y % Indosol dye
6 g/l sodium sulphate anhydrous
d) Adjust pH to 4.5 – 5 with acetic acid.

II – One Bath Method with Foron RD/
Indosol Dyes
Same process as with PES normal but with 120°C
fi xation temperature.
For these two processes, the dyeing will be fi xed
with Indosol E – 50.
For pale shade we recommend Optifi x WEI liq.
III – Two Bath Method with Cationic/
Drimaren K or CL and HF Dyes
For better brilliance and high wetfastness properties
we can dye this blend with two baths – cationic
dyes/cold reactive.
1. Dyeing the PES anionic component with cationic
dyes in the 1st bath.
0.5 – 1 g/l Thiotan R paste
6 g/l sodium sulphate
0.5 g/l sodium acetate
x % Cationic dye
y % Nylosan dye
pH 4.5 acetic acid 80%
