Definitions

  • 1: 1 metal complex dyes are often used for dyeing wool, because these dyes are characterized by good leveling and dyeing properties.
  • 1: 1 metal complex dyes have good balancing properties on wool of different origins.
  • sulfuric acid is generally used and - with considerable restrictions regarding the choice of color - occasionally also formic acid.
  • dyeing aids which are generally ethoxylated fatty alcohols or fatty amines, are usually used.
  • the disadvantage of the wool dyeing process mentioned above is that the wool can be severely damaged, particularly with longer dyeing times. Textile materials made of wool that are dyed under these conditions appear to be particularly susceptible to further damage in subsequent finishing operations. In order to minimize the damage to the wool when dyeing with 1: 1 metal complex dyes, attempts have already been made to reduce the sulfuric acid concentration to 4% by weight, based on the weight of the goods. In most cases, however, this measure is not sufficient to prevent damage to the wool during subsequent further finishing operations.
  • the present invention has for its object to provide a method for dyeing wool with 1: 1 metal complex dyes in aqueous solution in the presence of acids at pH values below 4 and dyeing aids, in which the wool is not damaged to the extent becomes, as is the case with the known methods.
  • the object is achieved according to the invention with a process for dyeing wool with 1: 1 metal complex dyes in an aqueous liquor in the presence of acids at pH values below 4 and dyeing auxiliaries if amidosulfonic acid is used as the acid.
  • the wool can be present in all processing stages, for example as a yarn, flake, comb, knitwear or fabric. This also applies to blends of wool with other fibers, e.g. polyacrylonitrile and polyamide fibers.
  • sulfuric acid can be used in addition to amidosulfonic acid to adjust the pH of the liquor.
  • Higher sulfuric acid concentrations on the other hand, already cause noticeable damage to the wool during dyeing.
  • the coloring is carried out in the temperature range from 40 to 105, preferably 60 to 100'C. It ends after 45 to 120 minutes.
  • the dyeing is optionally carried out in the presence of dyeing aids.
  • dyeing aids are preferably ethoxylated fatty alcohols and ethoxylated fatty amines or mixtures thereof.
  • the dyeing auxiliaries are used in an amount of 0 to 4, preferably 1 to 2% of the weight of the goods in a long liquor.
  • the liquors can additionally up to 2 Gew.X a monosulfonic acid C 1 -C 18 -Alkylnapthalin- or a C l - to C 10 -Dialkynaphthalinmonosulfonklare and / or disulfonic acid contained.
  • dialkylnaphthalene monosulfonic acids can also be used, for example ethylhexylnaphthalene monosulfonic acid, dibutylnaphthalene monosulfonic acid, diethylnaphthalene monosulfonic acid or mixtures of ethylnaphthalene monosulfonic acid and dibutylnaphthalene monosulfonic acid. Mixtures of mono- and disulfonic acids can also be used.
  • 1 metal complex dyes are commercially available. For further characterization of these dyes, reference is made to the color index. Chromium and cobalt are preferred metals.
  • a measure of the damage to the wool during dyeing is the alkali solubility of the wool.
  • the alkali solubility of the wool was determined by immersing 0.5 g of wool pretreated in a certain manner for 60 minutes at 65 ° C. in 50 ml of 0.1N sodium hydroxide solution. Weight loss is determined as the difference between the dry weight of the sample before and after the treatment (standard of the Technical Committee of the International Wool Association).
  • Example 1 is repeated with the exceptions that instead of amidosulfonic acid 6 Z, based on the weight of the product, sulfuric acid and 1 kg of the reaction product of 1 mol of oleylamine with 12 mol of ethylene oxide are now used. After a dyeing time of 1, 2 and 3 hours, the alkali solubility of the wool is again determined. The results obtained are shown in Table 1.
  • a strand dyeing apparatus 100 kg of wool yarn are treated in 2,000 l of water for 10 minutes at a temperature of 50 ° C., and 1 kg of the reaction product of 1 mol of oleylamine and 12 mol of ethylene oxide is then added. Then 6 kg of amidosulfonic acid and 5 kg of crystallized sodium sulfate are added and the liquor is circulated for 10 minutes. Then put 1.5 kg of the yellow dye of the formula and 0.41 kg of the blue dye of the formula III in the form of the 1: 1 chromium complexes as an aqueous solution.
  • the temperature of the liquor is then raised to 100 ° C. within 45 minutes.
  • the material is dyed for 60 minutes at cooking temperature, then samples are taken, which are then dyed for a further 2 or 3 hours under the conditions mentioned.
  • the product is cooled, rinsed cold and the wool is dried. Uniform coloring is obtained in all cases.
  • the alkali solubilities of the wool after the dyeing times given above are shown in Table 2.
  • Example 2 is repeated with the exception that the same amount of sulfuric acid is used instead of 6% amidosulfonic acid.
  • the alkali solubility of the wool was determined on material samples after 1, 2 and 3 hours of dyeing in the presence of sulfuric acid. The results are shown in Table 2. From this it can be seen that the wool is considerably less when using only amidosulfonic acid is damaged than when using sulfuric acid by a method according to the prior art.
  • the dyed wool obtained according to Example 2 after a dyeing time of 1 hour was aftertreated with a reaction product of piperazine and epichlorohydrin partially quaternized with benzyl chloride, by post-treating the dyed wool for 10 min at a temperature of 45'C in a liquor which weighed 1 kg of the cationic condensation product mentioned and 4 kg of sodium acetate in 2,000 1 of water.
  • the wet fastness achieved in this way was significantly higher than that of the untreated wool.
  • the liquor is then pumped over again and heated to boiling temperature within 30 to 45 min and dyed at this temperature for 60 min. Then part of the material is rinsed thoroughly, dewatered and dried while two other samples are stained for a total of 2 or 3 hours at the boiling temperature and then rinsed, dewatered and dried.
  • the alkali solubility is determined for all samples. The values obtained are given in Table 3. After a dyeing time of 1 hour, there is a level violet color of excellent macro and micro levelness. The packages are easy to unwind, the yarn is easy to knit.
  • Example 4 is repeated with the exception that the dyeing at a liquor ratio of 1:20 in the presence of 5% sulfuric acid, based on the weight of the goods, and 1% of a reaction product of 1 mol of a C 16 / C 18 fatty alcohol and 30 mol Performs ethylene oxide. After a dyeing time of 1, 2 or 3 hours, the alkali solubility of the wool is determined. The values are given in Table 3.
  • Example 5 is repeated with the exception that the dyeing is carried out in the presence of 4% sulfuric acid, based on the weight of the goods, and 1% of a reaction product of 1 mol of oleylamine with 12 mol of ethylene oxide. After a dyeing time of 1, 2 or 3 hours, the alkali solubility of the wool is determined. The values are given in Table 4.
