Definitions

  • Stabilizing the licker liquor with anionic and nonionic emulsifiers such as alkyl sulfates, alkylarylsulfonates or fatty alcohol ethoxylates, is out of the question because of the increase in water absorbency.
  • DE-OS-1 669 347 discloses the use of water-emulsifiable sulfosuccinic acid esters for greasing leather, but no waterproofing effects are achieved.
  • EP-A-0 165 481 describes a process for the production of leather and furs, a combination of sulfosuccinic acid esters with certain anionic or nonionic emulsifiers during chrome or aluminum tanning or retanning being used as the fatliquor in the tanning liquor. A waterproof effect is not achieved with this method either.
  • the invention thus relates to a process for the production of waterproof leather or furs using sulfosuccinic acid monoesters in combination with impregnating and / or hydrophobizing greasing agents, characterized in that the leather or furs are subsequently impregnated in an aqueous liquor with impregnating and / or hydrophobizing agents Fatting agents that contain sulfosuccinic acid monoester salts with C 12 -C 24 fat residues, treated and fixed after acidification by adding a chromium and / or aluminum salt.
  • the sulfosuccinic acid monoester salts are preferably used in combination with impregnating fatliquoring agents. These include, in particular, oxidized or oxidized and partly sulfonated C 18 -C 26 hydrocarbons or C 32 -C 4 O waxes, Phosphorklamon O C 12 -C 24 -alkyl esters, partial esters of polycarboxylic acids such as Citronenhoffreniono-C 6 -C 24 -alkyl Partial esters of polyalcohols, such as sorbitan, glycerol or pentaerythritol C 16 -C 24 fatty acid esters.
  • the proportion of sulfosuccinic acid monoester salts in the fatliquor combination is 10 to 60, preferably 20 to 40 percent by weight.
  • greasing agents are used in licker lubrication, depending on the type of leather, in an amount of 5 to 20 percent by weight, based on the shaved weight of the leather.
  • the leather When the sulfosuccinic acid monoesters are used in combinations with neutral oils, such as long-chain hydrocarbons, chlorinated paraffin, animal and vegetable oils and fats or their methyl esters and chlorinated fatty acid methyl esters, the leather also has a reduced water absorbency if acidified after greasing and then with chromium and / or aluminum salts is fixed.
  • neutral oils such as long-chain hydrocarbons, chlorinated paraffin, animal and vegetable oils and fats or their methyl esters and chlorinated fatty acid methyl esters
  • fatty agents containing sulfosuccinic acid monoester salts can also be used in part in normal leaching with sulfated, sulfited and / or synthetic fatliquors based on chloroparaffin sulfonates, depending on the proportion of impregnating and / or hydrophobizing fatliquoring, a more or less pronounced water resistance is achieved.
  • the sulfosuccinic acid monoester salts are prepared in a known manner by esterification of maleic anhydride with approximately one equivalent of the desired esterification component and subsequent reaction with an amount of a sulfite or bisulfite approximately equivalent to the maleic anhydride, e.g. B. according to DE-OS-1 669 347.
  • esterification component fat residues with 12 to 24 carbon atoms and compounds containing hydroxyl groups are suitable.
  • the fat residues can be saturated or unsaturated. They can be derived from fatty alcohols or fatty acid mono- or diglycerides, e.g. B.
  • the sulfosuccinic acid monoester salts are preferably prepared as sodium or ammonium salts, but other alkalis or organic amines can also be used as cations.
  • Water-soluble chromium and / or aluminum salts are used to fix the sulfosuccinic acid monoester salts.
  • the application amount is 1 to 10 percent by weight in the liquor.
  • the claimed process is carried out in such a way that the sulfosuccinic acid monoester salts and, if appropriate, further fatliquoring agents are used as a licker after the retanning and, if appropriate, dyeing and subsequent washing out of excess tanning agent. High temperatures above 50'C can be avoided.
  • the aftertreatment is initially carried out in a customary manner by acidification, preferably with formic acid, it being possible, if appropriate, to precede a brief treatment with a polyacrylate tanning agent. Then fix with the chrome and / or aluminum salts at about pH 3.5.
  • the claimed fatliquors are well absorbed by the leather and are distributed very evenly over the entire leather cross section. They have a remarkable resistance to water and give the leather excellent waterproofness, especially under dynamic loads. The result is soft, firm-grain leather with a pleasantly slim handle, which are particularly suitable for the production of upper leather, clothing velor and fur velor.
  • the leathers showed good softness, coloring and sanding with a pronounced beading effect.
  • the sheepskins are worked up to the hair color as usual via switches, laundry, pimples / tanning, retanning and greasing.
  • the velor color is impregnated according to the following procedure.
