ABSTRACT:
The invention relates to a process for fixing reactive dyes on cellulosic textile material and to apparatus for carrying out said process.
The process comprises wetting the dried fibre material, which has been printed with reactive dyes, with water, covering the printed material with water-impermeable material and subjecting it to a heat treatment. The fixation can be carried out with advantage using minor amounts of urea, but preferably without urea, to give prints of good quality.
