Kraftkolour Acid Milling Dyes are a range of bright, strong colours with good light and wash fastness. They have relatively few dyebath additions; Glauber Salt (to slow uptake of dye and assist in achieving even dyeings) and Acetic or Texacid to achieve a pH between 4.5 and 5.5

Apart from dyeing any Protein Fibre, most of these dyes work well on silk and nylon.
