Acid Dyes are used for dyeing protein fibers. The main protein fibers used for which acid dyes are used are wool, angora, cashmere and silk. Apart these, milk protein fibres like Silk Latte, Soya Protein etc., can also be used. It has a scary sound to some novices that seems to be due to strong caustic soda. But, in reality these dyes are non-caustic acids and in some cases, these are also non-toxics also. In fact in some cases mild acids like vinegar are used in the dyeing process. Some such mild acids are more toxic than the fiber reactive dyes and some are less toxic and even safer to eat.
Metal-complex dyes that are otherwise known as pre-metallized dyes shows great affinity towards protein fibers. Generally it has been seen that metal complex dyes are Chromium or Cobalt complexes. Among the popular metal-complex dyes, a variety known as 1:2 metal-complex dyes finds application for dyeing polyamide fibers. For dyeing wool, metal complex dyes are the most favoured. The following table shows a comparison between 1:1 metal-complex and 1:2 metal complex dye.
