Definitions

  • the present invention relates to a process for the discontinuous dyeing of strand-like textile material made of linear polyester fibers in a mixture with wool and dyes which are suitable for these types of fibers and which are suitable for these types of fibers according to the pull-out technique, the feed for the transport of the goods within the self-contained system via the actuation of the nozzle system by means of the kinetic energy of a circulated gas stream which is not inert with regard to the dyeing behavior of dyes and textile material, the dyeing liquor is simultaneously added to this flowing gas in the nozzle section for the goods drive and thus brought into contact with the textile material in accordance with the preselected temperature and pressure conditions, where it acts directly under fixing conditions.
  • the common dyeing of the two components of polyester fiber / wool blends in the drawing process is generally known.
  • the wool portion of the textile goods is usually colored with acid, metal complex or reactive dyes, depending on the authenticity requirements in practice, the disperse dyes required for dyeing the polyester fiber component usually being in the same bath and often also being fixed simultaneously.
  • the disperse dyes are fixed either at cooking temperature or at a temperature around 106 ° C with the help of carriers, or under high temperature (HT) conditions (120 - 125 ° C) without the use of a carrier.
  • HT high temperature
  • the latter HT process for dye fixation requires the addition of wool protection agents in the case of the special composition of the fiber mixture to be dyed. Without this, the wool would suffer severe damage due to the high dyeing temperatures used.
  • Formaldehyde has proven to be the cheapest and most effective wool protection agent in this field.
  • European patent EP-AO 078 022 now describes a process for wet treatment, in particular for dyeing, according to which a gas stream in a jet dyeing machine takes over the advancement of the strand-like textile material to be finished, with isothermal conditions for carrying out the successive operations be created.
  • the dye liquor is then metered into the driving gas stream and brought into contact with the dye material under isothermal conditions.
  • the fleet is quickly distributed in the dye material and fixing processes of dyes on the respective fiber materials also start at the same time.
  • the liquor used therefor contains dispersed or dissolved dyes for both types of fibers and acid or buffer substances for adjusting a pH in the range from 4.5 to 6.5 in the aqueous medium used.
  • polyester fibers are preferably meant to be normally dyeable types of this fiber category, i.e. fibers that cannot be dyed carrier-free at cooking temperature as a result of a modification of their uniform polymeric fiber structure.
  • This object is achieved in that after the isothermal addition of the dye liquor containing the dyes for both types of fibers and pH regulators, the goods are first treated for 10-20 minutes at cooking temperature or at a temperature around 106 ° C., only then the dispersion / The emulsion of a carrier is metered into the driving gas stream and finally the coloring is completed in the course of a further 10 to 30 minutes under isothermal conditions.
  • the principle on which the invention is based namely the subsequent metering of the carrier emulsion into the driving gas stream, both achieves the full carrier effect and eliminates authenticity problems and leveling difficulties.
  • This new process provides perfectly level dyeings and, compared to the usual working methods for the same purpose, saves energy and chemicals and reduces the emission of waste water.
  • the color yield on both types of fibers is also improved according to the process due to the short liquor ratio used and the authenticity reductions as a result of the direct addition of carrier to the dye liquor in the initial stage of the treatment process are avoided.
  • all acid dyes suitable for wool are suitable for dyeing the wool portion;
  • a selection of such dyes from the class of disperse dyes can be made, which can be used according to carrier dyeing methods.
  • the blower of the piece dyeing system After loading the jet dyeing machine with the textile material made of polyester fibers and wool, the blower of the piece dyeing system is started and in this way the circulation of the strand-like material is achieved aerodynamically. Sometimes the loading process itself can advantageously take place with the participation of the gas flow generated by the blower. By adding steam to the flowing transport gas, both the heating of the goods together with the dyeing kettle loaded with them to a temperature of 100-106 ° C and also a moistening of the circulating strand are brought about.
  • the separately prepared dyeing liquor is metered into the heated gas stream via the injection pump serving the treatment agent additive and a nozzle system in the gas circuit.
  • It contains dyes for both types of fibers as well as pH regulators for setting a pH value between 4.5 and 6.5 and any other aids;
  • Their temperature is 80 - 100 ° C, so that the isothermal conditions on the goods are only slightly disturbed by the liquor supply, especially since the amount of liquid is dimensioned as short as possible, which is about 2-4 times the pure weight of the goods.
  • the sluicing process takes place over the duration of several rounds of the textile goods. Then this liquor is allowed to act on the rotating paint for about 10-20 minutes at 100-106 ° C.
  • the carrier preparation diluted with a little water (2-3 times the amount) of 60 ° C begins. Like the addition of the liquor, this is done via a metering pump and the atomizing nozzle, distributed over at least one circulation of the textile goods. After a further 10 - 30 minutes treatment time at 100 - 106 ° C, the measures for the dyeing operation are completed and the post-treatment of the fiber mixture dyed in this way can take place in the usual way.
  • a gabardine made of a wool / polyester fiber mixture (in a ratio of 45:55) is placed in a rope in a jet dyeing machine, circulated therein using a steam / air mixture, and at the same time moistened and preheated to 95 ° C.
  • the fabric then contains 50% of moisture resulting from condensed steam.
  • the temperature of the circulating liquor is raised to 100 ° C. by blowing in steam and the goods are dyed for 20 minutes under these conditions.
  • a fabric made of a polyester fiber / wool mixture (in a ratio of 55:45) is drawn into a jet dyeing machine, which allows isothermal dyeing in a gas stream, and then by means of a Steam / air mixture circulated, heated to 106 ° C and at the same time exposed to 200% of moisture formed by the steam condensation.
  • the dyed goods are cooled by adding less warm water to the dyeing jet, rinsed at the same time and then treated as in Example 1.
