  • the form 7 will advantageously have a core 13.
  • the form 7 will also present means for attaching the textile material which will allow it to be attached without trace, for example by means of needles or hooks.
  • a counterform 14 will be applied to the shape 7 which will allow on the one hand a good maintenance of the part 1 to be treated and on the other hand to perform marking lines for example to simulate false seams.
  • channeling and circulation means 11, 12 will consist of pipes, suitable for being heated, respectively connecting the various members as shown in FIG. 1 and on which valves 15 will be inserted to direct and to establish certain forced ciculation circuits by means of a circulation pump 16.
  • the installation 6 comprises means for preheating the support 2 of the textile material and / or the textile material 1 to avoid the cooling of the dye solution during the impregnation phase.
  • suction means 17 capable of creating the vacuum inside the enclosure 8.
  • the pre-heating means of the form 7 and / or of the part to be treated 1, as well as the means of progressive cooling of the part to be treated 1, are constituted by an inlet for gaseous fluid 18 which, according to a command not shown, will make it possible to fill the enclosure 8 with a gaseous fluid while circulating it from the reverse towards the location of the part to be treated 1, hot or cold respectively.
  • the temperatures of these fluids will be determined by a person skilled in the art as a function of the material to be treated and of the times allowed for preheating or cooling.
