Abstract (en)
[origin: WO2006027362A2] The invention relates to a method for maintaining a constant colour in a dyeing process that uses mixtures of substantive reactive dyes on substrates consisting of natural or modified fibrous materials that contain hydroxy groups. Said method is characterised in that during a dye process that takes place under laboratory conditions, a correction factor for adjusting the replenishment of the pad bath is indirectly or directly determined, in such a way that the initial concentration in the foulard trough remains constant during the entire dyeing process.
