  • This is moving hence that the voltage states during different Phases of the treatment process in uncontrolled Be resolved in a way and thereby a corresponding Uneven treatment effect on the textile goods results. Basically the same applies to signs of shrinkage, the during the course of treatment occur.
  • the new procedure will time before treatment with the treatment agent, e.g. B. the dye liquor, in at least one separate preparation or pre-treatment step through direct exposure to water vapor (Steaming) on the textile goods present in the textile goods Tensions are released and / or there is a shrinkage of the Textile goods causes.

This leads to that the line of goods better relocated so that the danger of permanent Wrinkle embossing in the textile goods reduced or completely is prevented. Because of the better opening can the textile goods are also better distributed in the store, so that the deformation in the fold area is significantly less is. This gives the textile goods the opportunity to to continuously relax the goods run, i.e. to relax so that, as explained above, the following Treatment steps for finishing the textile goods of a perfectly even, relaxed product going out, and no permanent in the dyeing process Deformations can occur more. With steam treatment and raising the textile material to the pretreatment temperature condensation of water vapor occurs on the textile fibers. The resulting resulting limited moisture absorption already causes a accordingly limited swelling of the textile fiber material, which in turn stabilizes the goods structure is achieved.

  • the temperature of this fleet is regulated via the heat exchanger so that a controlled Cooling of the gas stream passing over it occurs.
  • the cooling of the gas or steam flow takes place through the direct contact with the colder treatment fleet and through the proportion of condensate resulting from the proportion of water vapor precipitates and at the same time heat the gas withdraws.
