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 inside the self-contained system takes place 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 in atomized form is added to this flowing gas in the nozzle section for the goods drive and so on brought into contact with the textile material in accordance with the preselected temperature and pressure conditions, where it comes into effect immediately 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 will 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-BO 078 022 now describes a method 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. This gives the dye a quick distribution of the dye and at the same time fixing processes of dyes on the respective fiber materials begin.
  • the liquor used therefor contains dispersed or dissolved dyes for both types of fibers and acid or buffer substances in the aqueous medium used to adjust a pH in the range from 4.5 to 6.5.
  • 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 / Emulsion of a carrier is metered into the driving gas stream and finally the coloring is completed in the course of a further 10-30 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 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 also 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. This liquor is then allowed to act on the rotating ink 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 introduced into a jet dyeing machine in the form of a rope, circulated therein by means of 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.
  • the circulated treatment bath is drained off; the dyed goods are now cooled by adding less warm water to the dyeing jet and rinsed at the same time and then for 20 minutes at 75 ° C. with a freshly prepared, aqueous bath with the addition of 0.5% acetic acid and Containing 2 g / l of an auxiliary 40% with 36 moles of oxyethylated castor oil, 42% Ca-phenylcogasinsulfonat as well 16% isopropanol aftertreated at a liquor ratio of 1:10. Finally, the dyeing produced in the manner indicated is rinsed again with water, hot and cold, and dried.
  • a fabric made of a polyester fiber / wool mixture (in a ratio of 55:45) is drawn into a jet dyeing machine, which permits isothermal dyeing in a gas stream, and then circulated by means of a steam / air mixture, to 106 ° C. heated and at the same time exposed to 200% of moisture formed by the steam condensation.
  • the injector system now contains 20% more moisture in the form of water at 95 ° C 2% ammonium acetate, 2% acetic acid (60%) and 1.5% of a leveling agent based on the reaction product of 1 mol of stearylamine with 12 mol of ethylene oxide infiltrated and distributed on the goods.
  • the temperature of the treatment bath is kept at 106 ° C. After about 5 minutes, an aqueous liquor of 95 ° C. is obtained in the same way, corresponding to an additional moisture amount of 180% 0.06% of the dye Disperse Yellow 64 with the CI no. 47023, 0.87% of the dye Disperse Blue 56 with the CI no.
  • a blue disperse dye based on a mixture of differently brominated diamino-dihydroxy-anthraquinones with less than 1 mole of bromine per mole of dye.
  • a blue disperse dye based on a mixture of differently brominated diamino-dihydroxy-anthraquinones with less than 1 mole of bromine per mole of dye.
  • 0.04% of the reactive dye of the formula 0.22% of the reactive dye of the formula and 1.9% of the reactive dye of the formula applied to the dye and then dyed at 106 ° C for 20 minutes.
  • the dyed goods are cooled by adding less warm water to the dyeing jet, rinsed at the same time and then aftertreated as in Example 1.
