Definitions

  • the task was to avoid the problem of oversaturated or too little concentrated vats in continuous dyeing.
  • aqueous dispersions of vat dyes are suitable which contain dyes with a vatting half-life of, 20, preferably ⁇ 5 minutes.
  • the dyes can be used, for example, in very small pieces.
  • the dyes or preparations supplied by the well-known vat dye manufacturers are usually already suitable. In the case of dyes which have not already been optimized, they can be converted into a suitable form by known methods, for example ultrasound dispersion.
  • the rate of vatting is essentially determined by the chemical structure, the crystallinity and crystal structure as well as by the particle size. Given the chemical structure, high vatting rates are obtained, for example, from amorphous, finely divided dyes.
  • a high vatting rate is desirable because the concentration of non-veined dye in the diving liquor is kept low.
  • Another possibility for limiting the concentration of non-coated dye in the immersion bath results from the metering of the dye via a bypass mixing tank.
  • vat dyes can be used both individually and in combination.
  • the dye supply can be controlled by separate metering devices.
  • Suitable substrates to be dyed are cellulose yarns or blended yarns containing cellulose, which are then primarily processed into denim articles.
  • the number of dives usually varies between 1 and 8. Depending on the dye and reducing agent, color temperatures of 20 to 95 ° C can be used.
  • Suitable compounds are those known for vat dyeing, for example sodium dithionite, thiourea dioxide or organic reducing agents such as hydroxyacetone. Mixtures of reducing agents are also suitable.
  • Dyes suitable for the process according to the invention are, in particular, the compounds listed in the Color Index under vat dyes and combinable dispersion dyes, if appropriate after appropriate dispersion.
  • Preferred are e.g. C.I. Vat Blue 5 (C.I. 73065), C.I. Vat Orange 2 (C.I. 59705), C.I. Vat Blue 4 (C.I. 69800), C.I. Vat Red 32 (C.I. 71135), C.I. Vat Green 1 (C.I. 59825), C.I. Vat Green 9 (C.I. 59850) or Disperse Yellow 54 (C.I. 47020).
  • the dye is fixed on the yarn, which must be replaced continuously to prevent the dye baths from becoming poor, i.e. add 50 g of dye per minute. It is continuously added as a dye dispersion in 1 liter of water. This dye dispersion is constantly stirred slowly.
  • a brilliant blue color is obtained with the desired properties of low through-coloring (ring coloration) and thus a slight wash down.
  • a slightly dyed Bw yarn is obtained which has the properties required for colored denim in the wash (wash down).
