Definitions

  • the invention relates to a process for the fat filling of fur skins and the use of certain monocarboxylic acid partial esters for the fat filling of fur skins.
  • Wool fat as such is difficult to incorporate into fur skins due to its pasty consistency. It is therefore usually liquefied with mineral oils, which considerably improves the penetration of the wool fat into the fur skins.
  • the fur skins are first subjected to an extraction with solvents, mineral oils being extracted practically quantitatively and wool fat due to its poorer solubility only to a small extent.
  • the fur skins are then cleaned to remove adhering wool fat from the skins.
  • the object on which the invention is based was therefore to develop constant-quality whale oils which give fur skins consistently good performance properties. Furthermore, the whale oils to be developed should not have their own smell, be liquid and be easy to incorporate into fur skins.
  • the invention relates to a process for the churning of fur skins, wherein the fur skins are drummed at 30 to 50 ° C. with chalk oils containing C 12-18 monocarboxylic acid diglycerol partial esters and / or C 12-18 monocarboxylic acid triglycerol partial esters and then the monocarboxylic acid partial adhering to the fur skins can be removed in a manner known per se by refining.
  • Another object of the present invention is the use of C 12-18 monocarboxylic acid diglycerol partial esters and / or C 12-18 monocarboxylic acid triglycerol partial esters for the fat greasing of fur skins.
  • the whale oils according to the invention can contain non-volatile hydrocarbons, for example mineral oils and / or alkylbenzenes, the content of hydrocarbons resulting from the desired viscosity and from the desired penetration capacity of the whale oils to be used.
  • non-volatile hydrocarbons for example mineral oils and / or alkylbenzenes
  • Most of the liquid carboxylic acid partial esters to be used according to the invention already have such a good penetration ability into the fur skins that there is no need to add hydrocarbons.
  • the whale oils according to the invention can contain complex-active emulsifiers, for example C 8-22 citric acid alkyl esters and / or phosphoric acid esters of alkoxylated C 8-22 fatty alcohols, and / or nonionic emulsifiers, such as alkoxylated C 8-22 fatty alcohols.
  • the monocarboxylic acid partial esters to be used in whale oils according to the invention can be prepared in a manner known per se by esterifying linear and / or branched-chain, saturated and / or unsaturated C 12-18 carboxylic acids with diglycerol and / or triglycerol in the presence of catalysts, for example sulfuric acid, p-toluenesulfonic acid or Caustic soda, with and without
  • Suitable C 12-18 carboxylic acids of natural and / or synthetic origin are, for example, lauric acid, myristic acid, palmitic acid, C 16 gueretic acid, pamitolic acid, stearic acid, 2-methylheptadecanoic acid, oleic acid, C 20 gueretic acid.
  • Guerbet acids can be prepared from fatty alcohols, which are converted into Guerbet alcohols in the presence of alkaline catalysts and then oxidized to the corresponding Guerbet acids (G. Dieckelmann and HJ Heinz: "The Basics of Industrial Oleochemistry, pp. 145-147, Peter Pomp GmbH 1988).
  • the monocarboxylic acid partial esters are used in amounts of 50 to 400 g per fur skin.
  • the greasing is carried out, for example, in a hammer or crank roller.
  • the whale oils are either applied to the skins before drumming or added directly when drumming.
  • the walking time is usually between 1 and 3 hours.
  • the skins are thinly cut in a manner known per se - unless tanned, thinly cut fur skins are already used - and refined in a refining drum with sawdust, which are moistened with water and wetting agents, in order to remove superficially adhering carboxylic acid partial esters from the skins.
  • the whale oils according to the invention are liquid and have a water absorption or emulsification capacity which corresponds to an above-average wool fat quality. Furthermore, most carboxylic acid partial esters already have such good penetration ability in the skins that the use of hydrocarbons, for example mineral oils and / or alkylbenzenes, is unnecessary. If the whale greasing is carried out with whale oils that contain no or only small amounts of mineral oils, there is no need for solvent extraction before the refining process and the disposal problems of solvent-containing extraction residues are eliminated.
  • Fur skins that have been greased with whale oils containing carboxylic acid partial esters are very soft and supple, have a significantly better odor and very good light-fastness and heat yellowing properties compared to fur skins that have been treated with wool grease.
  • Triglycerin esterified with 2.5 mol oleic acid Triglycerin esterified with 2.5 mol oleic acid.
  • the fur skins treated with one of the whale oils A, B or C were refined in a refining drum with sawdust moistened with water and some wetting agent for one hour. Then the used sawdust was replaced by fresh, again sawdust moistened with water and wetting agent and cleaned for one hour. The used sawdust was then replaced by dry one and refined for another hour.
  • the fur skins treated with the commercial whale oil were extracted in a closed system in a Böwe degreasing system in a closed system 2 x 3 minutes with perchlorethylene and then refined in a refining drum with sawdust which had been moistened with water and a little wetting agent for 2 hours.
  • the fur skins treated with one of the whale oils A to D were placed in a shaking drum and the sawdust adhering to the skins was removed within 30 minutes.
  • the fur skins were refined with dry sawdust in a refining drum for one hour and then removed from adhering sawdust in a shaking drum within 30 minutes.
  • the overall judgment is not an average of the individual values. The overall impression is assessed in the overall judgment.
