Definitions

  • the ratio of components (A): (B) in the tanning liquor is preferably 85: 15-50: 50 percent by weight.
  • the components can be added to the fleet separately or in the form of a made-up product.
  • the sulfosuccinic acid esters (A) are prepared in a known manner by esterification of maleic anhydride with 1 to 2 equivalents of the desired esterification component and subsequent reaction with an amount of a sulfite or bisulfite which is approximately equivalent to the maleic anhydride. Fat residues with 12 to 24 carbon atoms and compounds containing hydroxyl groups are suitable as esterification components.
  • the fatty reeds can be saturated or unsaturated, straight or branched. They can be derived from fatty alcohols, branched chain alcohols produced by oxosynthesis, or fatty acid mono- or diglycerides e.g. B. C 12 -C 18 coconut fatty alcohol, C 16 -C 18 tallow alcohol C e -C 24 oxo alcohol, C16-C1s tallow fatty acid monoglyceride, or of adducts of 1 to 6 mol of alkylene oxide with the fatty alcohols or fatty acid glycerides mentioned or with fatty acids, e.g. B.
  • sulfosuccinic acid esters are used in the form of their salts, preferably sodium and / or ammonium salts.
  • Suitable emulsifiers (B) which are used in combination with the sulfosuccinic acid esters (A) are, for example, the adducts of 5 to 25 mol of ethylene oxide with Ce-C2o-fatty alcohols or -alkylphenols such as C 12 -C 18 coconut fatty alcohol + 8 EO, C 16 -C 18 tallow fatty alcohol + 20 EO, nonylphenol + 9 EO, or the sulfates of the adducts of 1 to 6 moles of ethylene oxide with Ce-C2o fatty alcohols, fatty acids or fatty acid alkanolamides, e.g. B.
  • the sulfosuccinic acid esters, together with the emulsifiers, are added to the tanning or retanning liquors before, during or after the addition of tanning agents, depending on the leather type desired, 0.1 to 6.0 percent by weight, preferably 0.5 to 4.0 percent by weight, of active substance, based on the nakedness -or fold weight, can be used.
  • the fleets are characterized by good durability. Leather or fur skins of very good softness are obtained. The solid grain is significantly improved compared to the commonly used sulfitation products.
  • sulfosuccinic acid esters (A) and emulsifiers (B) can be used together with conventional electrolyte-resistant fatliquors, such as sulfited oils, e.g. B. fish oil, or by sulfochlorination and subsequent saponification of unsaturated fatty acid esters, such as tallow fatty acid methyl ester, or long-chain paraffins, e.g. B. chloroparaffinsulfonate, are used in the tanning liquor.
  • conventional electrolyte-resistant fatliquors such as sulfited oils, e.g. B. fish oil, or by sulfochlorination and subsequent saponification of unsaturated fatty acid esters, such as tallow fatty acid methyl ester, or long-chain paraffins, e.g. B. chloroparaffinsulfonate
  • Base material cowhide chrome-tanned, rebate thickness 1 mm
  • Base material cowhide, chrome-tanned fold thickness 1.6 mm

B) 10 à 60 % en poids d'agents émulsionnants non ioniques et/ou anioniques choisis dans le groupe constitué par les produits d'addition des oxydes d'alcoylène sur les alcools gras, les alcoylphénols, les acides gras ou les alcanolamides d'acides gras en C8-C20 ainsi que de leurs esters sulfuriques sous forme de leurs sels alcalins d'ammonium ou d'amine, .

cette combinaison étant utilisée en une quantité totale de 0,1 à 6 % en poids rapporté au poids plané ou au poids plissé.
2. Procédé selon la revendication 1, caractérisé par un rapport entre les composants A et B tel que 85 : 15 à 50 : 50 % en poids.
3. Procédé selon les revendications 1 et 2, caractérisé par l'utilisation d'esters sulfosucciniques A dont les fractions d'estérification dérivent d'alcools gras, ou de mono- ou de diglycérides d'acides gras en C12-C24 ou de produits d'addition de 1 à 6 moles d'oxyde d'alcoylène sur des alcools gras ou des mono-ou des di-glycérides d'acides gras, ou des acides gras en Cl2-C24.
4. Procédé selon les revendications 1 à 3, caractérisé par l'utilisation, comme agents émulsionnants (B), de produits d'addition de 5 à 25 moles d'oxyde d'éthylène sur des alcools gras, des alcoylphénols, des acides gras ou des alcanolamides d'acides gras en Ca-C2o et/ou d'esters sulfuriques des produits d'addition de 1 à 6 moles d'oxyde d'éthylène sur des alcools gras, des acides gras ou des alcanolamides d'acides gras en Ca-C2o sous forme de leurs sels alcalins ou d'ammonium.
5. Procédé selon les revendications 1 à 4, caractérisé par la mise en oeuvre de 0,5 à 4 % en poids des constituants A et B rapporté au poids plané ou plissé dans le jus de tannage ou de post-tannage.
6. Procédé selon les revendications 1 à 5, caractérisé par l'utilisation simultanée d'agents de graissage stables aux électrolytes dans le jus de tannage.
