  • Conditioning of texturized filament yarns
    Patent number: 4247291
    Abstract: Process for conditioning texturized filament yarns, which comprises treating the yarn, after dyeing, with a fatty acid hydroxyalkylethylene diamine condensation product obtained by condensation of 1 mol of hydroxyethyl- or hydroxypropylethylene diamine with 1.2 to 1.8 mols of one or several C.sub.12-22 fatty acids at 160.degree. to 220.degree. C.
    Type: Grant
    Filed: May 29, 1979
    Date of Patent: January 27, 1981
    Assignee: Hoechst Aktiengesellschaft
    Inventors: Helmut Vautrin, Gustav Dollinger
  • Heat-resistant fiber conditioning agents
    Patent number: 4102793
    Abstract: A process for the conditioning of synthetic fibers, which comprises applying onto these fibers mixtures of alkane-phosphonic acid salts and alkane-phosphonic acid-semi-ester salts in a molar ratio of from 19:1 to 5:1.
    Type: Grant
    Filed: April 20, 1976
    Date of Patent: July 25, 1978
    Assignee: Hoechst Aktiengesellschaft

  • Fiber preparation agents to produce a marked separating capability
    Patent number: 4095941
    Abstract: A process for the manufacture of synthetic staple fibers having a marked separating capability by preparing the synthetic fibers with fatty acid-amine-condensation products, which comprises preparing or conditioning the fibers, prior to the textile spinning processes, with fatty acid-hydroxy-alkyl-ethylene-diamine condensation products, the hydroxyalkyl radical or which shows 2 or 3 carbon atoms, and 1 to 2 identical or different radicals of saturated fatty acids having from 14 to 18 carbon atoms are present per mole of hydroxy-alkyl-ethylene-diamine.
    Type: Grant
    Filed: September 30, 1975
    Date of Patent: June 20, 1978
    Assignee: Hoechst Aktiengesellschaft
    Inventors: Ulrich Cuntze, Gustav Dollinger, Rolf Kleber
  • Conditioning agents for the texturizing of polyester fibers
    Patent number: 4080301
    Abstract: Conditioning systems for polyester fibers consisting of from 40 - 60% by weight of a lubricating agent and from 60 to 40% by weight of an emulsifying mixture, the total conditioning system showing a loss by evaporation of less than 5% by weight at 220.degree. C within 1 hour, a viscosity of less than 200 cP (20.degree. C), and in dilution with water in the ratio of 2:1, 1:1 and 1:2, a viscosity of less than 150 cP, less than 500 cP and less than 250 cP (60.degree. C), respectively. These compositions are applied onto the fibers by known methods. They impart especially good sliding properties to the polyester fibers during texturizing.

  • Preparation for the antistatic finishing of fibers
    Patent number: 3956143
    Abstract: Peralkylated reaction products of .alpha.-olefin oxides of 8 to 18 carbon atoms with lower alkylene-diamines, dialkylene-triamines or trialkylene-tetramines are fiber lubricants which are capable of rendering the fibers antistatic.
