ABSTRACT:
The invention describes a process for dyeing or printing natural or synthetic polyamide fibre material by a rapid fixation method, which comprises the use of dyes or mixtures of dyes of the formulae as defined in the description in a continuous dyeing method or printing method, and fixing the dyes or prints by steaming for less than 3 minutes such that at least 95% fixation of the dyes is achieved. The process is particularly suitable for combination dyeing and polyamide carpet printing, and produces level dyeings and prints having excellent fastness properties.
