Definitions

  • the invention relates to a method for greasing and simultaneously hydrophobizing leather, fur and leather substitutes according to the preamble of claim 1.
  • phosphoric acid esters of the general formula given in claim 1 it is preferable to start in a first reaction step from phosphorus oxychloride (POC1 3 ) and a diol X, which are condensed with elimination of hydrogen chloride.
  • the molar ratio of phosphorus oxychloride to diol is 2 to 1 to 1.1 to 1, preferably 1.5 to 1.
  • the condensation gives compounds of the general formula (1) in which z is an integer from 1-5.
  • Suitable diol X are linear or branched, saturated or unsaturated, acyclic diols with 2-16, preferably 2-10, carbon atoms, such as e.g. Butanediol-1.4, Hexanediol-2.5, Hexanediol-1.6 or Decanediol-1.10, Butene-2-diol-1.4 or Hexin-3-diol-2.5, or cyclic diols, e.g. Cyclohexanediol-1.4, or aromatic diols, e.g. Bisphenol A.
  • X can be a condensation product of ethylene oxide and / or propylene oxide and / or butylene oxide with 2-8 moles of alkylene oxide, e.g. Tripropylene glycol or polyethylene glycol 200.
  • the phosphorus compound of the general formula (1) is condensed (esterified) with a hydroxyl compound R in a second reaction step with elimination of hydrogen chloride.
  • Possible hydroxyl compounds R are linear or branched, saturated or unsaturated alcohols with 12-18 C atoms, or the abovementioned alcohols condensed with 1-6 mol alkylene oxide, such as e.g. Oleyl alcohol, tallow fatty alcohol, synthetic Alfol alcohols, isooctadecyl alcohol or oleyl alcohol with 4 mol ethylene oxide, furthermore phenols or alkylphenols with 6-30 C-atoms, e.g. Octylphenol, nonylphenol, dinonyphenol, dodecylphenol, or the corresponding ethoxylated phenols and alkylphenols (1-12 mol ethylene oxide).
  • 1-6 mol alkylene oxide such as e.g. Oleyl alcohol, tallow fatty alcohol, synthetic Alfol alcohols, isooctadecyl alcohol or oleyl alcohol with 4 mol ethylene oxide, furthermore phenols or alkylphenols with 6-30 C-atom
  • Saturated or unsaturated fatty acid esters are also used as the hydroxyl compound R, the fatty acid residue containing 8-22 carbon atoms and the ester component being polyalkylene oxides with 1-6 mol ethylene oxide, such as e.g. Tallow fatty acid with 6 mol ethylene oxide or oleic acid, esterified with polyethylene glycol 200, or a saturated or unsaturated mono- or diglyceride of a fatty acid with 8-22 carbon atoms per fatty acid residue, e.g. Oleic acid monoglyceride application.
  • Alkoxylated, saturated or unsaturated fatty amines with 8-22 carbon atoms per alkyl radical and condensed with 1-24 mol alkylene oxide, such as fatty acid mono- or dialkanolamides, can also be used.
  • Examples include coconut fatty amine with 12 mol ethylene oxide, tallow fatty acid amide with 10 mol ethylene oxide, oleic acid amide with 4 mol ethylene oxide and coconut fatty acid diethanolamide.
  • M stands for an alkali metal cation, for example Na + , K + or for the ammonium ion or for an organic, cyclic or acyclic ammonium compound, such as for example cyclohexylammonium, triethylammonium or monoethanolammonium ion.
  • the aqueous liquor used for oiling and waterproofing can be prepared by stirring the oiling and waterproofing agent used according to the invention into warm water (approx. 50 ° C .; 3 parts water to 1 part leather treatment agent). Such a liquor is sufficiently stable and is used for licking (i.e. treating in an aqueous system) chrome-tanned or vegetable and / or synthetically retanned leathers.
  • a particular advantage of the process according to the invention is the very strong affinity of the specified fatliquoring and hydrophobicizing agents for the fiber. This can be seen e.g. during extraction with dichloromethane (according to DIN 53306), in which the leather treatment agent can practically not be extracted from the fiber.
  • the leathers that are treated according to the claimed process are characterized by good softness and suppleness and a pleasant feel.
  • the particular advantage of the leather treated by the process according to the invention lies in the extraordinarily high dynamic water resistance achieved at the same time.
  • the leathers obtained are very soft and supple, have a dry silky feel and show excellent dynamic water resistance when tested on the "Bally penetrometer” (according to IUP / 10; “Das Leder", 1961, 38).
  • Chrome grain leather is retanned in the usual way with 2% of a synthetic tanning agent, dyed and licked with 5% leather treatment agent according to the formula in claim 1.
  • the percentages above refer to the weight of the leather.
  • X ethylene glycol
  • R coconut fatty alcohol
  • M ammonium
  • z 3.
  • chrome grain leather is retanned with 20% vegetable tanning agents and licked with 6% leather treatment agent according to the formula in claim 1 in 100% liquor.
  • the percentages above refer to the weight of the leather.
  • X 1,4-butanediol
  • R nonylphenol polyglycol ether (5 mol EO)
  • customary leather additives are added to the leather greasing and waterproofing agent as required, for example neutral leather treatment agents such as oils, fats, chlorinated oils and fats, chlorinated paraffins.
  • neutral leather treatment agents such as oils, fats, chlorinated oils and fats, chlorinated paraffins.
