Process for the dyeing or printing and simultaneous finishing of cellulose materials

摘要

A process for the dyeing or printing and simultaneous finishing of cellulose materials is described, in which process these materials are impregnated with an aqueous liquor comprising a specific dyestuff which contains at least one hydroxyalkyl radical or a cycloalkyl radical having at least one hydroxyl group, a synthetic resin-forming intermediate, formaldehyde or an agent releasing formaldehyde, an acid catalyst and, optionally, further additives, then dried, steamed or cold- stored, and finally subjected to a treatment at elevated temperature and, optionally, subsequently rinsed.PPDyed cellulse materials are obtained which have very high dyestuff yields, and which are dyed and printed evenly and fast to light and to washing; the resulting finishing effect is not strong and hence the effect on the handle of the material less, a condition which is particularly desirable in the case of light fabrics and therefore of great advantage.
