Natural dye combined to a synthetic shading agent.

2. PHYSICAL AND CHEMICALS PROPERTIES

Aspect : powder

Color : black

Solubility in water : good

pH (10 % solution) : 6.5 +- 1.0

Odor : spicy

Colour on leather : bluish black

3. CHARACTERISTICS

VEGDYE VO is a natural penetrating dyestuff of good quality/price ratio for obtaining through-dyed leather.

As every natural compound, it is advantageous to disperse VEGDYE VO by addition of a dispersing agent such as Syntex APH, before dyeing.

VEGDYE VO is sensitive to concentrated mineral acids and it is advised not to use it at pH under 4.0.

This dyestuff does not contain any ferrous/ferric salts or derived products prohibited by the regulations (such as benzidine, Pb, Cd and so on ...)

4. APPLICATIONS

VEGDYE VO is specially formulated for quick through-dyeing in black. SYNTEX APH speeds up dye penetration and reduces dyeing time even at temperature of 25°C.

We advise to dissolve VEGDYE VO in hot water (one part VEGDYE VO for two parts water) before adding it in the drum using very short bath or, preferably, no bath.

If fatliquors are correctly selected, VEGDYE VO can be used in the proportion of 2 % on shaved blue weight after neutralisation of chrome leather.

In order to improve light fastness and strengthen the colour, it is recommended to add 0.3 to 0.5 % synthetic dye at the end of the dyeing operation.
