Definitions

  • the present invention relates to fatliquors based on mixtures of modified, native oils with alkoxylated alkanols, their use in the production and / or treatment of leather and hides, and to processes for the production and / or treatment of leather and hides with these fatliquoring agents.
  • greasing agents serve to soften the leather, to increase its fullness and strength and to protect it from moisture, dirt and chemical influences from outside (see H. Herfeld, "Library of Leather” 1985, Volume 4, p. 13 et seq.).
  • Commercial greasing agents generally consist of greasing substances, such as native fats, native oils, waxes, resins and their derivatives and / or petroleum fractions and their secondary products, and wax-like products such as "wool fat", in raw, cleaned and / or prepared ( Lanolin) form (see H. Herfeld, "Bibliothek des Leders” 1985, Volume 4, pp. 59 ff.)
  • the fatty substances can - if desired - be chemically modified, ie they can have a modified chemical structure.
  • the chemical modification of the greasing substances generally consists in that the double bonds contained in these substances are at least partially subjected to addition reactions or oxidation reactions. Modifications that are frequently carried out include, for example, the addition of sulfites, which introduces sulfonic acid groups into the fatty substances, or air oxidation, which introduces oxygen functions and, in some cases, oligomerizations also occur. However, (partial) hydrolysis of the fats, transesterifications and similar modification reactions are also possible.
  • the DUST 75201 defines "fogging" as the condensation of evaporated components from the vehicle interior such as the upholstery leather on the glass panes, especially on the windshield. This can lead to a deteriorated view through the windshield, especially when driving at night, and thus to a safety risk.
  • the fogging behavior of leather is characterized by a gravimetric and a reflectometric method.
  • EP-A 0 498 634 recommends special polymers for the production of leathers with so-called "low fogging" properties.
  • the aqueous dispersions used in leather treatment are essentially free of organic solvents and contain an amphiphilic copolymer. This copolymer consists of a predominant proportion of at least one hydrophobic monomer and a minor proportion of at least one hydrophilic monomer.
  • Leather treatment with these dispersions leads to good results in a gravimetric test according to DLN 75201. Reflectometric studies have not been described.
  • amphiphilic copolymers are preferably prepared by emulsion polymerization in aqueous solution. Due to the different hydrophilicity of the monomers to be used, problems naturally arise in the copolymerization behavior. In extreme cases, this can lead to the monomers undesirably forming homopolymers on their own. Another consequence of the inherently unfavorable solution ratios is an expensive work-up to destroy unreacted monomers. In order to achieve good emulsion stability, it is also necessary to use a sufficient amount of an emulsifier (in the examples given Lauryl sulfate was used), which can lead to wastewater problems in leather processing.
  • an emulsifier in the examples given Lauryl sulfate was used
  • EP-B 0 466 392 describes a process for the preparation of polymers which contain both pendant hydrophobic groups and pendant hydrophilic alkoxylated groups. Such polymers are obtained by carrying out derivatization reactions after the actual polymerization process — known to the person skilled in the art. Thus, polymers are preferably produced from simple monomers such as acrylamide and / or acrylic acid by conventional polymerization and then derivatized with a mixture of primary or hydrophobic amines or primary or secondary alkoxylated amines. The polymers described are used as thickeners and soil release agents. Their use in leather treatment is not described.
  • polymeric fatliquoring agents are produced by polymerizing acrylic acid and / or methacrylic acid and / or their acid chlorides and / or their anhydrides with further copolymerizable water-soluble monomers and with copolymerizable water-insoluble monomers and subsequent reaction of the polymers thus obtained with amines ,
  • DIN 75201 B gravitation test
  • fogging values of 1.2 mg and 1.5 mg were found for leather that has been treated with these polymeric lubricants.
  • the leather treated with the comparative products Magnopal ® SOF low-fogging polymer greasing agent from Stockhausen GmbH & Co.
  • Chromopol ® LFC low-fogging greasing agent based on fish oils from Stockhausen GmbH & Co. KG
  • the reflectometric values according to DN 75201 A of the polymeric fatliquoring agents are 51% and 55%, that of the comparative products 34% and 40%.
  • amphiphilic copolymers are preferably prepared by aqueous emulsion polymerization.
  • this again leads to the problems already mentioned in the discussion of EP-A 0498 634.
  • EP-B 0 753 585 describes a low-fogging surface treatment for furniture leather in which specially treated native oils, which have less than 3% of fatty acid components with less than 16 carbon atoms, act as the basis for fatliquoring agents.
  • Native oils used are soybean, lard, safflower and sunflower oil. The said native oils are first distilled to remove the undesirable low molecular weight constituents and then reacted with hydrogen sulfite or hydrogen sulfate in order to improve the emulsifiability. Then the (partially) functionalized oils are emulsified and applied.
  • a special emulsifier composition comprising three components A, B and C is used according to the applicant's unpublished DE-A 101 43 949.0.
  • Component A is a C 6 -C 1 -alkanol alkoxylated with 4 to 12 alkylene oxide units, or a mixture of several such alkanols
