• the dye mixture of the invention is preferably subjected to the exhaustion process initially from an acidic dyebath having a pH of about 3.5 to 5.5 under pH control and the pH is then, toward the end of the dyeing time, shifted into the neutral and perhaps weakly alkaline range up to a pH of 8.5 to bring about, especially for very deep dyeings, the full reactive bond between the dyes of the dye mixtures of the invention and the fiber. At the same time, the dye portion not reactively bound is removed.
• the procedure described herein also applies to the production of dyeings on fiber materials composed of other natural polyamides or of synthetic polyamides and polyurethanes.
• the material to be dyed is introduced into the bath at a temperature of about 40°C, agitated therein for some time, the dyebath is then adjusted to the desired weakly acidic, preferably weakly acetic acid, pH and the actual dyeing is carried out at a temperature between 60 and 98°C.
• the dyeings can also be carried out at the boil or in sealed dyeing apparatus at temperatures of up to 106°C. Since the water solubility of the dye mixtures of the invention is very good, they can also be used with advantage in customary continuous dyeing processes.
• the color strength of the dye mixtures of the invention is very high.
• the dye mixtures of the invention is by generally known processes for dyeing and printing fiber materials by the known application techniques for fiber- reactive dyes. Since the dyes of the dye mixtures according to the invention are highly compatible with one another, the dye mixtures of the invention are also advantageously useful in exhaust dyeing processes. Applied in this way for example to cellulose fibers from a long liquor ratio at temperatures between 40 and 105°C, optionally at temperatures up to 130°C, under superatmosphe c pressure, and optionally in the presence of customary dyeing assistants with the use of acid- binding agents and optionally neutral salts, such as sodium chloride or sodium sulfate, they produce dyeings in very good color yields with excellent color build-up and consistent shade.
• One possible procedure is to introduce the material into the warm bath, gradually heat the bath to the desired dyeing temperature, and complete the dyeing process at that temperature.
• the neutral salts which speed up the exhaustion of the dyes can also if desired not be added to the bath until the actual dyeing temperature has been reached.
• the conventional printing processes for cellulose fibers which can either be carried out in single-phase, for example by printing with a print paste containing sodium bicarbonate or some other acid-binding agent and the colorant, and subsequent steaming at from 100 to 103°C, or in two phases, for example by printing with a neutral or weakly acid print paste containing the colorant and subsequent fixation either by passing the printed material through a hot electrolyte-containing alkaline bath or by overpadding with an alkaline electrolyte-containing padding liquour and subsequent batching of this treated material or subsequent steaming or subsequent treatment with dry heat, produce strong prints with well defined contours and a clear white ground. Changing fixing conditions has only little effect on the outcome of the prints.
• the hot air used in dry heat fixing by the customary thermofix processes has a temperature of from 120 to 200°C.
• the customary steam at from 101 to 103°C, it is also possible to use superheated steam and high pressure steam at up to 160°C.
