Definitions

  • the invention relates to brightener preparations which contain a cationic optical brightener, an anionic surfactant and optionally other additives.
  • the preparations can be in solid or liquid form.
  • M to receive such a brightener, for example, characterized in that, at least one anionic surfactant, and optionally further additives in an aqueous medium, mixing at least one cationic optical brightener together and optionally dried.
  • Particularly preferred brighteners are DE-OS 2 821 116, DE-OS 2 040 189 and DE-OS 1 670 999 described in the following references.
  • the anionic surfactants can be used in the form of the free acid or in the form of their water-soluble salts.
  • the concentration of the cationic optical brightener in the preferably liquid aqueous preparation is in the range from 1 to 10%, that of the anionic surfactants from 3 to 40% and that of the further additives likewise from 3 to 40%.
  • the brightener preparations according to the invention are produced by homogenizing the cationic optical brighteners together with the anionic surfactants and possibly the other additives in an aqueous medium and, if necessary, dissolving them with heating.
  • the solution can be filtered in order to separate undissolved constituents or impurities.
  • the homogenization is carried out according to known methods with e.g. High-speed stirrers, rotor-stator mills, dissolvers or similar devices.
  • liquid preparations can be dried using known drying processes.
  • the brightener preparations according to the invention are outstandingly suitable for the production of dyeing liquors for whitening polyacrylonitrile fibers by the exhaust process, preferably with a bleaching of the fiber material carried out in a separate bath, for example with sodium chlorite.
  • this preparation produces brilliant green tints.
  • this preparation can achieve a 60-fold higher concentration.
