Alternatively this process of the invention may be conveniently brought about by applying a printing paste containing one or more of the water-insoluble reactive dyestuffs to the cellulose textile material and thereafter immersing the printed textile material in a hot aqueous solution or suspension of the acid-binding agent or alternatively impregnating the printed textile material with an aqueous solution or suspension of the acid-binding agent and subsequently subjecting the printed textile material to the action of heat or steam.
After applying the printing paste to the cellulose textile material the printed textile material may, if desired, be dried, for example at a temperature between 20 and 100 C., before subjecting the printed textile material to the action of heat or steam.
At the conclusion of dyeing and/or printing processes it is preferred to subject the so-colored cellulose textile materials to a soaping treatment, which may be carried out by immersing the colored cellulose textile materials for a short time, for example 15 minutes, in a hot aqueous solution of soap and/ or detergent, and subsequently rinsing the colored cellulose textile material in water before drying it.
By the term water-insoluble reactive dyestufi there is meant a disperse or Water-insoluble dyestufi which is free from sulphonic acid and carboxylic acid groups and which contains (a) at least one reactive halogen atom or other reactive atom or group, that is to say a halogen atom or other group which is capable of reacting with the cellulose textile material whereby the dyestulf is attached to the cellulose textile material by a chemical bond and (b) one or more hydroxy groups. Examples of classes of such water-insoluble reactive dyestutfs include waterinsoluble dyestuffs containing, besides the one or more hydroxy groups, at least one 1:3 :S-triazinyl radical carrying one or two chlorine or bromine atoms directly attached to the triazine ring, or at least one pyrimidyl radical carrying one, two or three chlorine or bromine atoms directly attached to the pyrimidine ring, or at least one 'y-halogeno-fi-hydroxypropylamino group, or at least one di-(y-halogeno-fi-hydroxypropyl)amino group, or at least one B-halogenoalkylsulphamyl group, or at least one ,9- halogenoethoxy group, or at least one ,B-halogenothioethane group, or at least one 'y-halogen-p-hydroxypropylsulphamyl group, or at least one chloracylamino group, or at least one halogenoacyl group, or at least one sulphonfluoride group, or at least one vinylsulphonylamino group, or at least one halogenoethylsulphonyl group, or at least one thiocyano group, or at least one alkylor arylsulphonyloxyalkylsulphonyl group, or at least one alkylor arylsulphonyloxyalkylarninosuphonyl group, or at least one alkylor arylsulphonyloxyalkylamino group, or at least one alkylor arylsulphonyloxyalkoxy group, or at least one alkylor arylsulphonyoxyalkylaminocarbonyl group, or at least one acryloylamino or trichloroacryloylamino group, or at least one vinylsulphonyl group, or at least one epoxypropyl group.
