Above the stirrer there is a tubular goods carrier on which the polyester fabric to be dyed is wound. After the dyeing autoclave is then filled with the supercritical fluid containing the dye, this supercritical dyeing liquor is circulated through the stirrer arranged on the base.
- the known dyeing apparatus described above may be one Dyeing of polyester yarns in supercritical fluids on a laboratory scale enable, but is not suitable in Practice to dye textile substrates. This depends on it together that depending on the color on a practical scale the respective color depth considerable amounts of the dye supercritical fluid must be added to achieve the desired Adjust color. Furthermore, it is with practice coloring required by adding a dye or to nuance the color once achieved with several dyes, however, this is not the case if the one used in each case Staining autoclave already with the supercritical dye liquor is filled.
- the present invention is based on the object To provide methods of the specified type with which is possible to set an adjustable one within a very short time Amount of dye used for coloring add supercritical fluid.
- the first thing to be dyed textile substrate arranged the yarn spools in an autoclave.
- the textile substrate to be dyed is then autoclaved with a at least one supercritical dye Fluid flows through and / or flows.
- the supercritical fluid used for this with the respective dye or dye combination, with or with which the coloring is to be carried out is loaded in the method according to the invention first an auxiliary fluid with the corresponding dye or Dye combination applied. Then this auxiliary fluid loaded with dye or dyes with the supercritical used in the inventive method Fluid brought into contact, so that afterwards the textile Substrate with the at least one dye flows or flows through supercritical fluid.
- dye in the present application includes not just a single dye but also a mixture of dyes, such a mixture of Dyes usually consist of three to twelve dyes exists, usually used in practice for dyeing becomes.

- a particularly fast Dye transfer from the auxiliary fluid to the supercritical Fluid then takes place when that temperature, in particular the mixing temperature between 100 ° C and 170 ° C, preferably is between 120 ° C and 160 ° C.
- auxiliary fluid is the actual coloring process of the textile substrate is not adversely affected it is up to this auxiliary fluid in the supercritical fluid to leave at the end of the actual dyeing process.
- Add dye with the necessary auxiliary fluid is enriched so that with increasing staining time there is also an increasing amount in the supercritical fluid of auxiliary fluid.
- This process variant of the invention Process is preferred for such stains applied in light tones or medium tones be carried out and / or where the used in each case
- Auxiliary fluid for the corresponding dye is such a good one Solubility has only a relatively small amount of auxiliary fluid are required to the amount of dye required for coloring to supply the supercritical fluid.
- the auxiliary fluid in the supercritical fluid becomes the auxiliary fluid in the supercritical fluid during and in particular after the dye has been applied partially or largely on the textile substrate to be dyed removed from the supercritical fluid.
- This process variant of the method according to the invention is always then applied when the solubility of the auxiliary fluid in the supercritical Fluid is limited when the solubility of each dyes used in the auxiliary fluid are relatively low and if dark according to the inventive method Hues are to be created, i.e. if in this case Auxiliary fluid a relatively large amount of dye used must provide supercritical fluid.
- Another embodiment of the method according to the invention which are preferably used for dyeing polyester yarn Coils, especially X coils, that in this embodiment of the method according to the invention a variety of bobbins wound with polyester yarn in the autoclave, preferably in a cylindrical autoclave, arranged to form at least one coil column becomes.
- the method according to the invention enables one optimal transport of the supercritical loaded with the dye Fluids to any location on the coil column, so accordingly especially level dyeings also result.
- a coil column is not like from known in the aqueous process, flows radially but axially, accordingly, the flow of the dye loaded supercritical fluid within the autoclave of the lower face of the lowest coil to the upper face the top coil or vice versa.
- a particularly favorable procedure allows another Embodiment of the method according to the invention, wherein at this embodiment, an autoclave is used, each only takes up a single coil column.
- the advantage of this Process variants can be seen in the fact that such Autoclave measured relative to its axial length has a small diameter, so that the manufacturing costs for such an autoclave also reduced accordingly are.
- this diameter preferably with an axial flow the coils between 100 mm and 800 mm, especially between 200 mm and 400 mm, vary.
- the yarn packages selected as textile substrates flows axially, which means that the A large number, in particular two to twenty, of one above the other Coils are flowed through so that the Supercritical liquor loaded with dye from the lower end face of the coil the lowest coil to the upper coil face the top coil and / or from the top coil face the top coil to the bottom coil face the bottom coil is guided.
- the method according to the invention is also particularly suitable to make polyester sewing threads wound on bobbins, in particular in the form of your presentation as X-coils.
- sewing threads in particular includes polyester-containing threads Yarns or polyester yarns, such sewing threads then the constructions which are known and customary for sewing threads have.
