3. CHARACTERISTICS

As every product containing natural dyes, VEGDYE AFS is particularly recommended for quickly obtaining through-dyed leather with very competitive quality/price ratio.

On chrome leather, VEGDYE AFS gives a brown, homogenous shade throughout the leather with good levelling at the surface.

In order to obtain brighter and light fast colour, we suggest to use 0.2 to 0.5 % of direct dye at the end of the process.

VEGDYE AFS can possibly be mordanted with metallic salts to produce a very bright brown with Al2 (SO4)3 and khaki brown with Fe(SO4).

- Upper leather, corrected grain

- Very thick leathergoods

- Suede

- Splits
