  • the object of the present invention is a method of the specified type and a corresponding device to make available, even with such dyes, that tend to cake or sinter together, a quick and particularly easy introduction of the respective Allows dye in the supercritical fluid.
  • the method according to the invention for dyeing a textile substrate in at least one supercritical fluid provides, like the known method, that the respective arranges textile substrate in an autoclave and there with the at least one supercritical fluid containing dye flows towards or through.
  • the at least one fixed, preferably powdery, dye with the supercritical Fluid to form a stable solution and / or dispersion of the dye in the supercritical fluid.
  • the invention Process compared to the prior art more complex appears because in the method according to the invention amount of dye to be dissolved or dispersed to a variety of dye subsets divided and separately one after the other has been introduced into the supercritical fluid
  • the inventive method in particular for critical, for clumping or for sintering together tending dyes, compared to the previously practiced Dyeing process does not require an increased amount of time.
  • the inventive Processes relatively small amounts of dye a relative large amount of supercritical fluid is offered, so that accordingly the dissolving or dispersing process of the dye in the supercritical fluid accelerates without a clumping or sintering together of the related Partial dye amount could be observed.
  • the method according to the invention is also capable of adding Inert particles or on the creation of a specific dye granulate size to do without, as is the case with critical dyes is the case with the known method.
