Definitions

  • the fur is usually treated with a pickling solution before coloring with oxidation dyes.
  • the purpose of the stain is to make the dyeings light, washable, storable and sublimation-free.
  • the stains on a stain are much more intense and vivid.
  • Metal salts mainly chromium and iron salts, in rare cases copper salts, are used as pickling agents.
  • the present invention relates to a process for dyeing fur skins with oxidation dyes, in which the fur skins are first pretreated and then dyed, which is characterized in that the fur skins are pretreated with a metal stain containing glyoxylic acid.
  • Metal salts mainly chromium or iron salts, are used as pickling agents.
  • the dichromate concentration is usually between 0.1 and 7 g / l pickling liquor, the pH of the stain being in the range between 3 and 5. It has been shown that at higher pH values between pH 5 and 7, only a little dichromate is absorbed, even if the concentration is chosen to be relatively strong. If the pH values are lower than 3, the hair already hardens. The amount of dichromate to be applied to the hair can therefore be regulated by the pH value and also by the dichromate concentration.
  • a mild pickling effect is achieved on the one hand with a quantity of dichromate of 2 to 5 g / l pickling liquor if the acid addition is low and on the other hand with a quantity of dichromate of 0.3 to 0.5 g / l pickling liquor at a pH of 3.5 to 4.
  • a strong pickling effect is achieved with 0.5 to 1 g dichromate per liter pickling liquor at a low pH.
  • Glyoxylic acid is used to adjust the pH, but the addition of other acids, e.g. Formic acid, acetic acid or glycolic acid is conceivable.
  • the content of glyoxylic acid per liter of pickling liquor depends on the desired pH and is between 1 and 7 g / l pickling liquor.
  • the amount of acid is about 1.5 to 3 g glyoxylic acid per liter pickling liquor. If the addition of acid is too low, uneven colorations are obtained, and if the addition of acid is too high, the coloring becomes weaker than with normal addition of acid.
  • the acid addition also plays a special role in iron pickling. Iron stains with too little acid tend to oxidize. The baths become cloudy due to the formation of yellow-brown basic ferrisulfate and ferrihydroxide and, when standing, deposit brown sludge. A sufficient amount of acid, preferably glyoxylic acid, in the stain can prevent the formation of the poorly soluble iron compounds. Usually 1.5 to 3 g of glyoxylic acid, based on one liter of pickling liquor, are added to the iron stain.
  • stains which contain combinations of the metal salts with one another are also suitable. These include: the copper-iron stain, the chrome-copper stain, the iron-chrome alum stain and the copper-chrome alum stain.
  • the mordants used according to the invention usually contain a certain amount of degreasing agent.
  • Preferred degreasing agents are fatty alcohol polyglycol ethers with 5-12 EO units, e.g. ®Remolgan CX, ®Genapol UD O50, ®Genapol UD O80 (manufacturer: Hoechst AG).
  • the usual addition of strong acids such as formic acid and / or acetic acid is not necessary but is conceivable.
  • the ratio of glyoxylic acid to strong acid is usually 9: 1.
  • the composition of the metal stain that is used in practice is listed below 0.5 g to 3 g of at least one metal salt, preferably potassium dichromate 1.5 g to 3 g glyoxylic acid and 0.5 g to 1 g of degreasing agent, based on one liter of pickling liquor.
  • the glyoxylic acid is usually added to the pickling liquor in the form of an aqueous solution, preferably 40-50% by weight.
  • the pickling process is generally carried out in reels, fur turns or closed vessels (drum, barrel).
  • the temperature is advantageously 20 to 40 ° C, while the duration varies between 3 and 24 hours.
  • the skins are rinsed briefly, if necessary, then spun well and finally come to the dye bath. Thorough rinsing is never beneficial, as otherwise some of the pickling salts that are absorbed will be washed out again.
  • the purpose of rinsing is only to remove excess metal salts and acids. Are the stains, e.g. Dichromate stain, applied with little acid, so rinsing can be avoided. It is sufficient to centrifuge the skins well.
  • Black on mutation mink (Mink leather with 0.5% Cr2O3 content after finishing) Fleet 1:20, based on the dry weight of the skins Killing: not applicable Stain: 2.0 g / l potassium dichromate 1.5 ml / l glyoxylic acid (®Feliderm CS) 0.5 g / l degreasing agent (®Remolgan CX)
  • a total of 8.0 ml of H2O2 (30% by weight) / l of dye liquor are used for the oxidation.
  • the dyeing takes place at 35 ° C for a total of 6 hours.
  • the undercoat had a brown tinge. Recolouring was necessary here.
  • the dichromate content is 527 mg / l pickling liquor.
  • the leather side of the fur skins stained with glyoxylic acid is incomparably softer and more tear-resistant than that of those treated by the conventional method.
  • Black on mutation mink (Mink leather with 0.5% Cr2O3 content after finishing) Fleet 1:20, based on the dry weight of the skins Killing: 2.0 g / l soda calc. 2.0 ml / l ammonia (25% by weight) 0.8 g / l degreasing agent (®Remolgan CX)
  • a total of 8.0 ml of H2O2 (30% by weight) / l of dye liquor are used for the oxidation.
  • the dyeing takes place at 35 ° C for a total of 6 hours.
  • the leather side of the fur skins stained with glyoxylic acid is significantly softer and more tear-resistant than that of those treated with the conventional method.
  • the dichromate content after finishing the pickling is 478 mg / l pickling liquor.
