ABSTRACT OF THE DISCLOSURE: The present invention is concerned with a process for the after-treatment of dyed or printed synthetic fibers, or of materials which consist of synthetic fibers or contain a mixture of synthetic fibers and other fibers, using an aqueous solution which contains from 0.2 to 20 g/l of a mixture of from 80 to 20 parts by weight of a reductonate selected from the group consisting of mono- hydroxyacetone, dihydroxyacetone, dihydroxybutanone and glycolaldehyde;and from 20 to 80 parts by weight of one or more surfactants, the after-treatment being carried out at from 40 to 100°C and at a pH above 8. This invention is more particularly useful in that the process is carried out with a reducing agent which is stable in alkaline solution in the presence of atmospheric oxygen, but biologically degradable.
