What are Lanaset dyes?
A range of Wool dyes with a high level of fastness and almost identical dyeing properties. All colours are intermixable. Dyes are applied in hot water at pH 4.5, with a minimum of fibre damage.
What is the most commonly used acidic dye?
Most of the commercially available acid dyes are azo, anthraquinone or triphenyl methane-based. Although there are other acid dyes like azine, xanthane, nitro, indigoid, quinoline and carbolan dyes, these dyes are of limited commercial value. The most popular chromophore in acid dyes is the azo group.
