ACRIL SAF 107 is a retarder with .affinity to fibres and prevents a too rapid absorption of cationic dyes on the PAN fibre by occupying the reactive, anionic fibre groups.
ACRIL, SAF 107 has high retarding
in the heating - up phase, which is maintained for an extended period even
after reaching the final dyeing temperature, which is of special advantage for
PAN fibres with a higher dyeing rate. This
retarding effect is maintained for an
extended period even after reaching the boiling temperature. At this
temperature range ACRIL SAF 107 also develops
a good migration effect. On account of this
double action excellent levelling
effects are achieved with this product.
Coloristic index of : ACRIL SAF 107
The optimum amounts of ACRIL SAF 107
be applied depend on the
type of fiber,
depth of shade and on the dye-stuffs used.
Dyeing rate of the fibre
Dyestuff medium higher
2.5 - 2.0%
3.0 - 25 %
Starting temperature : 50-70°C
Run the materia shortly before adding the dyestuff. Then heat
up slowly to 98-105°C and dye for further 30-90 min.
The use of a special migrating auxliliary may be of advantage
in particularly difficult cases.
