Definitions

  • the present application relates to hydrophobizing agents for textile finishing, a process for the hydrophobic finishing of textiles and the use of certain fatty substances as Water repellents.
  • Hydrophobing agents are generally used to make textiles hydrophobic Based on polysiloxanes, fluorocarbons or mixtures of aluminum or Zirconium salts with paraffins used (see “Handbook of Textile Aids", A. Chwala, V. Anger, Verlag Chemie, New York 1977, Chapter 3.24 "Phobierstoff", page 735 ff).
  • the hydrophobic finishing of textiles, especially in weather protection clothing, serves to make them either water-repellent or water-impermeable.
  • the Hydrophobing agent is applied to the fibers of the textiles and is arranged there so that the hydrophobic parts of the molecule are perpendicular to the fiber surface. That way the striving of the water to spread over the entire area is greatly diminished.
  • aqueous emulsions for waterproofing textiles discloses a wax in combination with amine soaps in the form of an oil-in-water emulsion of saturated fatty acids and water-soluble nonionic surfactants as well as of aqueous Contain zirconium salt solutions.
  • US 3,180,750 describes aqueous agents for Waterproofing of textiles containing oxidized polymeric waxes and fat ketones have to. From US 2,759,851 it is known that aqueous wax dispersions, the amine salts and aluminum salts of aliphatic monocarboxylic acids and salts of aliphatic monocarboxylic acids with zircon are suitable for making textiles waterproof.
  • a hydrophobizing agent for textile equipment claimed which is in the form of an aqueous emulsion containing a zirconium salt Contains combination with a fatty substance which is selected from the group of branched or unbranched, symmetrical or asymmetrical dialkyl ethers with a total of 8 to 44 carbon atoms.
  • Zirconium acetate is particularly preferred.
  • the fatty substances are known alkyl ethers of the general formula R 1 -OR 2 , where R 1 and R 2 each represent alkyl radicals having 1 to 22 carbon atoms. The total number of carbon atoms in the molecule is 8 to 44. Both symmetrical ethers, ie R 1 and R 2 are identical, or unsymmetrical ethers (R 1 ⁇ R 2 ) can be used.
  • the alkyl radicals R 1 and R 2 can be saturated, unsaturated, branched or unbranched. Those ethers whose radicals R 1 or R 2 have a C chain length of 10 to 22 are particularly preferred.
  • the total carbon number of the ethers is preferably 20 to 44.
  • Preferred ethers are, for example, dibehenyl ether, distearyl ether, dipalmityl ether or dimyristyl ether.
  • An example of an unsymmetrical ether is ethylhexyleicosyl ether.
  • the ethers can be prepared by all known technical processes.
  • the water repellents according to the invention are preferably in the form of an aqueous Emulsion before. Water is then contained in amounts between 10 and 90% by weight.
  • the compositions preferably contain 30 to 80% by weight and in particular 40 to 60% by weight.
  • the zirconium salts are generally in amounts of 1 to 20 wt .-%, preferably in Contain amounts of 5 to 15 wt .-% and in particular in amounts of 5 to 10 wt .-%.
  • the Alkyl ethers are preferably contained in the agent in amounts of 10 to 95% by weight, in particular in amounts of 15 to 60% by weight and particularly preferably in amounts of 10 to 30% by weight.
  • the agents can include other salts and alkyl ethers contain suitable ingredients, especially emulsifiers, but also anti-slip agents, Wet fastness improvers, grip products, plasticizers, solvents, for example Ethanol, n-propanol or i-propanol and pH regulators, such as organic acids or bases.
  • the pH of the aqueous emulsions is in the acidic range, and is preferably less than 4.5 and in particular it is in the range from 2.0 to 3.5.
  • the auxiliary substances are in minor amounts between 0.5 and 5 wt .-% before. Usually contain the agents according to the invention total of such auxiliaries in amounts of at most 10% by weight.
  • the agents according to the invention are produced in a manner known per se by the Raw materials mixed with water, heated to temperatures between 40 and 90 ° C and homogenized. Average particle sizes of less than 250 nm should be achieved. The average particle sizes are preferably in the range from 100 to 200 nm Cooling can be used without further treatment.
  • the agents according to the invention are suitable for hydrophobic finishing of textiles made of synthetic or natural fibers, especially for Cotton textiles.
  • a method for the hydrophobic finishing of textiles claimed appropriately according to the above description means Applied textiles. Furthermore, the use of these agents for the hydrophobic finishing of Textiles claimed.
  • the agents were prepared as follows: The raw materials were presented, heated to 85 ° C and homogenized. The agents were then cooled to 20 ° C.
  • the agents had pH values in the range from 2.8 to 3.0.
  • the particle size was in the range from 200 to 250 nm.
  • the Schopper test was carried out in accordance with DIN EN 20811: test fabric 100% CO (approx. 300 g / m 2 ), equipped with 150 g / l emulsion. Fleet intake 86%. Drying at 140 ° C.
  • the friction resistance was tested with a continuous runner with 120 g / 1 liquor, 5 bar pressure and a speed of 20 m / minute.
  • the friction resistance was interrupted when deposits on the paddle roller were recognizable: medium Time for deposits to appear in minutes A 15 1 > 20 2 > 20 3 14 4 15
