Definitions

  • the present invention relates to a method for finishing felt-free wool. of wool fibers.
  • wool gradually becomes matted during washing or in general after prolonged contact with water, i.e. the individual fibers in woolen fabrics lose their elasticity and crimp and the textile material is compacted.

  • the disclosed device is not suitable for the finishing of fiber strands, in particular the felt-free finishing of wool fiber strands, but it must be possible to define concentration gradients that must be precisely set during the treatment process, or it must be possible to set a precisely defined concentration drop in the treatment bath as the treatment duration progresses to be able to.
  • the system proposed in FR-2 359 233 is particularly suitable for treating textile webs with treatment solutions which show no or only a very weak chemical reaction with the solid fiber material, ie the concentration of the treatment solution does not change or only slightly, as is the case with continuous impregnation or dyeing. If there is to be a stronger interaction between the so applied fleet and the textile goods, this takes place outside the application device, for example in a subsequent heater, dryer or steamer.
  • GB-PS 586 020 proposes wool or wool fibers in an acidic solution of potassium permanganate with a pH ⁇ 2, preferably in a pH range of 1.5-1.7, for a period of 1-2 minutes to treat a liquor ratio of 1 kg wool to 14 liter liquor.
  • this treatment only leads to acceptable results if either the wool is washed intensively before the treatment, or if it is provided with a wetting agent so that the wool fiber is holistically separated from it in the short treatment time of approx. 1 minute Wetting solution is penetrated.
  • the method described has not proven itself in practice, since an enrichment of the wetting agents washed out of the wool has resulted in the felt-free finish being impeded by excessive brownstone precipitations and corresponding inequality.
  • the method described in GB-PS 586 020 is not suitable for continuous processes. Therefore it will only examples of discontinuous batch treatments are given.
