Definitions

  • the present invention relates to the dyeing of textile fabrics or web articles made from cellulose fibers or mixtures thereof with synthetic fibers, with coupling component and diazo component in the form of a stabilized diazoamino or tetrazoamino compound or a diazotate on the fiber, by the Dye-forming components are applied continuously and together by direct transfer from an aqueous liquor containing these substances under alkaline conditions to the goods without dipping the textile goods therein, and the subsequent dye development is brought about by the action of acid.
  • the foulard technique has primarily been used so far.
  • a solution of the same is mechanically pressed (impregnated) onto the spread web by passing the substrate to be dyed through a bath (chassis) filled with treatment liquor and then squeezed off from the excess liquor.
  • a primer consists essentially of the alkaline solution of a coupling component (hereinafter also referred to briefly as "naphthol"), in particular of an arylamide of 2-hydroxy-3-naphthoic acid or an arylamide of ketocarboxylic acids.
  • naphthol a coupling component
  • the dye is developed by treating the previously mentioned primer with a solution of a diazonium compound (Azoic Diazo Component) under acidic conditions.
  • the purpose of the present invention is therefore to develop a process which succeeds in eliminating or circumventing the effect of the substantivity of the "naphthols", so that the single-bath continuous operation discussed above without impairing the color tone through the end drain can be realized.
  • Such a continuous process should neither include intermediate drying or necessary intermediate storage of the goods loaded with the dye-forming components, nor should special textile auxiliaries be required for wet-on-wet work. * ) and the color depth
  • fleet intakes by the Tex - tilgut in the range between 15% and 50% (based on the weight of the dry goods).
  • the "naphthol" does not have to be applied hot according to the invention.
  • Such a liquor can also be thickened, for example by adding glue, so that a very precise application of dye components can be carried out, which means that no excess dye is used in this way; the wastewater pollution is therefore much lower.
  • the process according to the invention is carried out, for example, by impregnating raw or ready-to-dye cellulose fiber fabric with an alkaline, thickened solution which contains a more or less substantive coupling component, a stabilized, non-coupling diazonium compound in the form of a diazoamino or tetrazoamino compound or an antidiazotate and optionally also contains a dispersant and / or a wetting agent.
  • the above-described impregnation liquor containing the dye-forming components can advantageously also be used in the form of a fine-pored foam. Due to the inherent consistency of such foams, a certain amount of the thickener can be saved in this variant.
  • the stabilized diazonium compound is converted into the couplable form by subsequent treatment of the textile webs, which have been pre-primed in accordance with the process, with acidic agents, which either consist of acidic steaming or an acid passage, so that a pH value between 3 and 6 is established on the goods coupling occurs and with it the formation of dye on the fiber. Finally, the coloring thus produced is then post-treated and finished in the manner customary in accordance with the ice color technique.
  • Suitable coupling components in the process according to the invention are predominantly those which have a low to medium substantivity towards cellulose fibers have.
  • Suitable compounds are, for example, 2,3-hydroxynaphthoylaminobenzene, 1- (2 ', 3'-hydroxynaphthoylamino) -2-methylbenzene, 1- (2', 3'-hydroxynaphthoylamino) -2-methoxybenzene, 1- (2 ', 3'-hydroxynaphthoylamino) -3-nitrobenzene, 1- (2 ', 3'-hydroxynaphthoylamino) -4-methoxybenzene, 1- (2', 3'-hydroxynaphthoylamino) -2-methyl-4-methoxybenzene, 1- (2 ', 3'-hydroxynaphthoylamino) -2,5-dimethoxybenzene, 1- (2', 3'-hydroxynaphtho
  • Coupling components with higher substantivity for example 2- (2 ', 3'-hydroxynaphthoylamino) naphthalene, 1- (2', 3'-hydroxynaphthoylamino) -2-methoxy-4-chloro-5-methylbenzene, 1- (2 ', 3'-hydroxynaphthoylamino) -2,5-dimethoxy-4-chlorobenzene, 2- (2 ', 3'-hydroxynaphthoylamino) -3-methoxy-diphenylene oxide or 1- (2'-hydroxycarbazole-3'-carboylamino) -4- Chlorobenzene can also be used in the process according to the invention. In contrast to other order processes, special measures that counteract substantivity can be dispensed with.
  • Diazoamino- or Tetrazoaminoeducationen those from diazotized aromatic or heterocyclic mono-or diamines, such as diazotized chloroanilines, Dichloranilinen, Chlortoluidinen, Chloranisidinen, nitroanilines, Nitrotoluidinen, Nitroanisidinen, Nitroxylidinen, Nitrophenetidinen, Cyantoluidinen, Cyananisidinen, Aminobenzolsulfonklareamiden, Aminobenzolcarbonklaamiden, Aminophenylalkyl-, aryl or aralkyl sulfones, aminodiphenyl ethers, trifluoromethylanilines, monoacylated phenylenediamines, aminoazobenzenes, 4,4'-diaminodiphenyls or amino carbazoles, and primary or secondary aliphatic or aromatic amines, for example N-alkylated aliphatic aminocarboxylic acids or
  • Suitable antidiazotates are likewise those compounds obtainable from the above-mentioned primary aromatic amines.
  • Suitable dispersants which can also be used in the alkaline impregnation bath are the compounds customary in ice color technology, for example condensation products from higher molecular weight fatty acids and protein degradation products, condensation products of formaldehyde with naphthalenesulfonic acids or purified sulfite cellulose waste liquor.
  • Alkyl aryl sulfonates are preferably used as wetting agents.
  • the acidic compounds in the development bath are organic acids, for example formic acid, acetic acid, propionic acid, or acidic salts, for example monosodium phosphate.
  • organic acids for example formic acid, acetic acid, propionic acid, or acidic salts, for example monosodium phosphate.
  • acidic salts for example monosodium phosphate.
  • a mixture of a salt of an organic acid and an organic acid for example a mixture of sodium acetate and acetic acid.
  • the process according to the invention can be applied to the known cellulosic fibers and mixtures of synthetic fibers, e.g. Polyester fibers, and cellulose fibers are used.
  • the cellulose fibers are native fibers such as flax, hemp, linen and cotton, or regenerated fibers such as viscose, rayon and modal fibers.
  • solution 2) is stirred into the bath batch and this is filled up with water at 70 ° C. to a total volume of 200 l.
  • the dyed material is impregnated by direct transfer without dipping it at 25 ° C. and with a liquor absorption of 40% using a device for minimal application described in European Patent EP-B-0 047 484.
  • this liquor is applied to the fabric at 20 ° C. and a liquor application of 40% by direct transfer without dipping it.
  • the web thus treated now passes through a chassis with an aqueous development liquor of 80 ° C., which contains.
  • the dyed textile material is then subjected to a short passage of air, then rinsed first with hot water, soaped at the boil, rinsed again with water and finally finished.
  • a deep Bordo coloration results on the goods.

  • the development of the azo dye on the fiber is now carried out by padding the material to be dyed with an acid solution at 80 ° C.
  • the impregnated cord is treated on the foulard with 100% liquor absorption, the textile material is then subjected to an air passage of 30 seconds at room temperature and the dyeing obtained in this way is rinsed in a wide washing machine with water at 70 ° C. in the first box.
