LANASET®

Dye type : Intelligent mixtures based on 1:2 metal complex, acid and reactive dyes

LANASET® is a well-balanced range, consisting of 15 products covering a huge color space. It is our main recommendation for silk dyeing.

On silk (SE), LANASET® shows excellent build-up and fastness and covers a much wider shade area compared to conventional metal-complex dyes. Its lightfastness properties are excellent. Silk is mainly dyed neutral (weakly alkaline to very-weakly acid) for maximum leveling. Lower pH promotes exhaustion but increases the risk of unlevelness, so it is restricted to deeper shades. When dyeing in the alkaline-to-neutral condition, exhaustion of the bath can be improved by gradual addition of salt towards the end of dyeing. Initial absorption of dye is very rapid so the "first strike" must be controlled by starting at low temperature, 20°C –30°C, and using an effective leveling agent.
