Definitions

• the present invention provides a process for printing textile materials of natural or regenerated cellulose by means of reactive dyestuffs.
• the reactive dyestuff is fixed fast on textile material of natural or regenerated cellulose by applying the dyestuff to the textile material in the first phase by means of a printing paste which contains water and a thickening agent and-after drying-padding the print in the second phase with an aqueous liquor which contains an agent having an alkaline reaction, steaming the material for to 30 seconds at about 110 to 115 C. and subsequently rinsing and soaping it, rinsing it again and finally drying it.
• reactive dyestuffs can be fixed fast on textile materials of natural or regenerated cellulose, without using the steaming process, by printing the reactive dyestuff on the textile material in the first phase by means of a printing paste which contains water and a thickening agent and-after dryingpadding the print in the second phase with an aqueous liquor which contains an agent having an alkaline reaction and exposing it subsequently to an air passage.
• the fixing process according to the present invention possesses several advantages. Since the steaming process is no longer necessary, a considerable amount of energy is saved per meter of printed material.
• the present invention possesses the advantage that the equilibrium reactive dyestuff+cellulose:reactive dyestuff-cellulose is shifted considerably in favour of the dyed cellulose.
• a reduction of the tinctorial strength can be 3,442,601 Patented May 6, 1969 avoided, particularly when dyestuffs are used which are easily resaponified at the binding dyestuff-fibre on steaming under the influence of alkalies.
• the reducing influence of the cellulose occurring at the steaming temperature provokes changes of the tints not only when individual dyestuffs are used but also when dyestuff combinations for obtaining combination shades are applied.
• organic dyestuffs there can be used according to the process of the present invention different organic dyestuff classes, for example, azo dyestuffs and anthraquinone dyestuffs which contain at least one of the known reactive groups such as for example, B-hydroxyethylsulfone.sulfuric acid ester groups, vinylsulfone groups, dichlorotriazine groups, ethionylamino groups, N-alkyl-ethionylamino groups, 2,2,3,3-tetrafluorocyclobutane-l-carbonylamino groups, 2-fluoro-2-chloro-3,3-difluorocyclobutanel-carbonylamino groups, 2,2,3,B-tetrafluorocyclobutane-1- acryloylamino groups, vinylsulfonylamino groups or 2,3- dichloroquinoxaline radicals.
• reactive groups such as for example, B-hydroxyethylsulf
• alkali metal hydroxides are preferably used as agents having an alkaline reaction.
• concentration of the agent having an alkaline reaction influences the necessary time during which the print is exposed to the air passage to such an extent that with the increasing concentration of alkali the required time of residence of the printed material in the air is reduced. If, for example, cc. of sodium hydroxide solution (38 B.) are used per liter of padding liquor, the required minimum time of exposing the print to the air passage is about 10 seconds. As a rule, the minimum time of exposing the print to an air passage is between 1 and 5 minutes. In general, it is preferable to adjust the concentration of alkali in the padding liquor in such a way that the pH-value is be tween about 13 and 14. The optimum concentration of alkali and the time of residence of the printed material in the air must be regulated in each case according to the reactive dyestufi' used.
• Suitable thickening agents are neutral thickening agents or thickeners having a weakly alkaline reaction such as, for example, alginates, different types of gum, or alkyl celluloses.
• EXAMPLE 1 40 parts of the dyestuff of the formula I SOaNa are dissolved in 300 parts of hot water after mixing with 50 parts of urea and introduced into 400 parts of an aqueous alginate thickener of 4% which contains 5 parts of a complex forming agent on the base of polymeric sodium meta-phosphate per 1000 parts of thickener. After addition of 15 parts of the sodium salt of meta-nitrobenzene sulfonic acid, the whole is made up to 1000 parts by the addition of 195 parts of water.

After drying, the printed fabric is padded with a liquor consisting of 100 parts by volume of sodium hydroxide solution (38 B.), 150 parts of sodium carbonate, 180 parts of sodium chloride, 50 parts of potassium carbonate and made up to 1000 parts by volume with water, and then exposed to an air passage for 30 seconds at C.
