Definitions

  • the invention relates to two-phase printing processes for the production of conversion articles with reactive and vat dyes and of etching reserve articles with reactive and optionally vat dyes on cellulosic fiber materials, the reactive dye or a mixture of reactive and vat dye being printed or padded with in a weakly acidic medium a neutral paste containing a stable reducing agent based on a sulfinic acid and optionally a vat dye is overprinted, after an intermediate drying the pressure is brought into contact with an aqueous, strongly alkaline liquor and dampened.
  • the fiber materials to be dyed are printed with mixtures of reactive and vat dyes set to be slightly acidic, and these prints after intermediate drying or advantageously in the same operation, overprinted wet in wet with printing inks, which are stable reducing agents in the neutral medium even under customary drying conditions, e.g. B. sodium formaldehyde sulfoxylate, in amounts of 100 to 200 g per kg of printing paste.
  • the printed fabric is up to 200 g through a strongly alkaline padding liquor with approximately 100 32.5 0 / cent sodium hydroxide solution per liter of liquor out or equivalent amounts of sodium or potassium carbonate or water glass, and then about 5 to 30 seconds, preferably 10 to 20 seconds, treated with saturated steam or superheated steam.
  • the dyes can also be used in other ways, e.g. B. by padding or splashing.
  • the alkali by other methods, e.g. B. by splashing or spraying, are brought into contact with the coloring.
  • Suitable reducing agents are primarily alkali metal or alkaline earth metal salts of sulfinic acids which have arisen from a reaction with aldehydes or amines and have thereby been stabilized, in particular sodium formaldehyde sulfoxylate.
  • Formamidine sulfinic acid thiourea dioxide is also particularly advantageous.
  • compositions of alginates and starch derivatives are advantageously used as the thickener; locust bean gum ether or cellulose ether may also be used.
  • locust bean gum derivatives instead of the alginates usually used in combination with starch ethers when adding the printing inks, or to cause the pH to shift towards the neutral point by adding alkali.
  • the technique described can now be transferred to the etched article by breaking down the original dye application into two steps, i. That is, the cellulosic fiber structure is printed with a printing paste containing the reactive dyes or the liquor is padded (or splashed), then dried and then, as described for the conversion article, printed with a printing paste containing a stable reducing agent and, if appropriate, one or more Vat dye (s) were incorporated.
  • the process then continues as shown above. Background and possibly colored etching colors are fixed after the alkali passage during the short steaming operation.
  • the durability of the printing inks and the prints before steaming is significantly better with a number of vat dyes than with the old etching printing processes with printing inks containing alkali and reducing agents.
  • DE-OS 1 929 231 and DE-OS 2 003 363 already describe processes which aim to apply reactive and vat dyes in padding liquors or printing inks together to textile substrates made of cellulose fibers and the action by different handling of the process steps to design the fixing aid in such a way that the two representatives of different dyestuff classes, in the course of two-phase processes, are undamaged and produce colorful pattern effects.
  • the interaction of reducing and oxidizing agents, the latter for protecting the reactive dyes, which is not easy to control even with the aid of different amounts of use, is of major importance. The difficulties associated with this have not given the methods described any access to practical implementation.
  • the aim is not to fix the reactive dye at the points where the vat dye is intended to fix. It is therefore not necessary to protect the reactive dye by adding more oxidizing agent; the relatively small addition serves only as a precaution against the coating of printing rollers due to the etching effect of the reducing agent.
  • the new process is therefore not in competition with the design methods according to the aforementioned DE-OS, but rather represents a significant improvement in the process technology previously used for the production of conversion and etching reserve articles.
  • the reactive dyes which can be used in the process according to the invention both in the case of the conversion article and the etching article can be obtained from various organic base bodies, such as, for. B. azo, anthraquinone or phthalocyanine compounds, and should have at least one ⁇ -hydroxyethylsulfonic sulfuric ester group, vinylsulfonyl group, monochlorotriazine group, dichlorotriazine group, 2,2,3,3-tetrafluorocyclobutane-1-acryloylamino group, vinylsulfonylonylamino group, vinylsulfonylonylamino group, Phenylsulfonylpropionylamino group or a 2,3-dichloroquinoxaline, monofluorotriazine, 2,4-dichloroquinazoline, 1,4-dichlorophthalazine, alkylsulfonylpyrimidine, tri- or tetrachloropyr
  • Suitable vat dyes include representatives with anthraquinone, indigoider and naphthoquinoid structure as well as naphthalene tetracarboxylic acid derivatives.
  • All substrates of cellulosic origin are suitable for the process according to the invention, that is to say both native products such as cotton or linen and regenerated cellulose such as cellulose or viscose and their highly wet-strength variants.
  • a cotton fabric is printed in a specific design with a printing ink of the following composition:
  • the printed fabric is overprinted wet in wet in a different design with a printing ink containing 200 g / kg sodium formaldehyde sulfoxylate in the same thickening.
  • the subsequently dried goods subsequently pass through an immersion bath with 100 g / l of 32.5% sodium hydroxide solution and 100 g / l of sodium carbonate and are then steamed in saturated steam for 20 seconds. After the steaming process, the pressure is thoroughly rinsed with cold water, treated at 40-50 ° C with 2 g / l hydrogen peroxide and 5 ml / l acetic acid, rinsed again and finally with 0.5 g / l sodium-oleic acid. N-methyl taurides washed at 90 ° C, rinsed and dried.

  • the printed goods are processed and finished as in Example 1.

  • the mildly dried product then passes through an immersion bath with 100 g / l of 32.5% sodium hydroxide solution and immediately afterwards a steamer in which it is steamed for 10 seconds in saturated steam.
