Dosage
For correct crosslinking of the finishing products, adjust the padding bath to pH 7 – 7.5 with sodium
bicarbonate. To obtain a better and more uniform wetting of the goods, add 1 – 3 g / L of BIOPAL 150 to the
bath.

50-80 g / L PERMANTEX 768
5 – 8 g / L sodium bicarbonate
For particularly difficult goods the dosage can be increased up to 100 g / L
Anti-pilling finishing
30 – 40 g / L PERMANTEX 768
20 – 30 g / L NOVASIL 302
1 – 2 g / L sodium bicarbonate
Properties
PERMANTEX 768 allows permanent anti-felting finishing, without pre-chlorination or oxidizing treatment, of
wool or wool blends. The product is suitable for finishing knitted or woven fabrics, garments (for example
pullovers and socks), and thick yarns in skeins.
The combination of PERMANTEX 768 with polyurethanes, such as NOVASIL 302, leads to a further
improvement in performance.
Applications
PERMANTEX 768 can be applied, alone or in combination with a polyurethane dispersion, by padding, by
spray or in a long bath. It is necessary to wash thoroughly before treatment, in order to eliminate the greasy
residues on the fiber, it is also advisable to check the pH of the material (uni en 1413 standard) and adjust
the value above 6 pH units, for a correct functioning of the finishing.
After applying PERMANTEX 768 , it is necessary to polymerize the material, drying at 100 – 160 ° C and
performing another pass in the stenter for 30-60 ‘at higher temperatures.
However, it is preferable to vaporize the goods for 3 minutes after drying in a decatizing machine the cross-
linking and decatizing operations ensure the optimization of the finishing and a pleasantly smooth hand.
If the polymerization does not take place in the stenter, it is necessary to make sure that the goods remain
rolled without creases until decatising.
In case of mixed colors with dispersed dyes it is necessary to apply PERMANTEX 768 exclusively after
dyeing to avoid a decrease in the rubbing fastness, furthermore polymerize the articles at temperatures
between 100 and 120 ° C and subsequently vaporize.
