Definitions

  • the invention relates to a method for liquid treatment of textile fiber material or the like, in particular for dyeing yarn, loose material or textile piece goods, in which the fiber material is introduced into a container, the container is evacuated dry, the treatment liquid is introduced into the container, the treatment liquid during a brought into effect for a certain time on the fiber material, the treatment liquid is removed from the container and the fiber material in the container is dried, if necessary after rinsing.
  • the performance of the known method has hitherto been limited in particular by the duration of action of the treatment liquid on the fiber material, which is necessary in the interest of a complete, uniform and, if necessary, gentle treatment or dyeing.
  • the continuous drying performance reduces.
  • the invention is thus based on the object, the B ehand- averaging time to shorten without uneven or not gentle treatment of the fiber material must be taken into account.
  • This object is achieved in that, before the treatment liquid is introduced into the container, the temperatures of the fiber material and the treatment liquid and the pressure in the container are coordinated with one another in such a way that when the treatment liquid is introduced, essentially no evaporating liquid condenses in or on the fiber material.
  • the invention is based on the insight that the evacuation of the container leads to a positivechromateitenden action on the fiber material, as the entrapped air bubbles expand by the pressure reduction, resulting in opening the fiber pores and the existing K apillarrus in terms of substantial increase of the input d iffundierens of the active ingredients of the treatment liquid influenced, so that, for example, larger dye molecules penetrate quickly into the fibers and can settle there.
  • the removal of moisture from the fiber material associated with the evacuation is advantageous since it can result in wetting with concentrated liquid which is not diluted by water adhering to the fiber material.
  • the treatment liquid introduced suddenly penetrates the fiber material with an undiminished concentration of the active ingredients, the fiber material being impregnated uniformly. It can be seen that the active ingredients can thus quickly diffuse into the fiber material. This results in a comparatively short treatment time, which also means that the fiber material is protected.
  • the teaching according to the invention of avoiding steam condensation in or on the fiber material can be followed in such a way that the fiber is introduced before the treatment liquid is introduced material in the container is preheated to the extent that no steam is deposited on it.
  • This preheating can expediently take place in that the fiber material is preheated by means of warm air flowing through the container.
  • the teaching according to the invention can also be followed in that the treatment liquid is introduced into the evacuated container at a low temperature which is below the evaporation temperature which corresponds to the reduced container pressure.
  • the temperature of the treatment liquid introduced is, for example, only 30 ° C.
  • the fiber material can be completely colored in a short time.
  • This process variant can therefore also be of particular importance because of the low load on the fiber material and, depending on the application, the resulting quality maintenance. Decreases in properties, such as matting of the material, can largely be avoided as a result of the comparatively short duration of treatment. After all, the savings in energy and operating costs are particularly high in this case.
  • This pressure which can be, for example, in the range from 1 to 1.5 bar, has, in addition to the prevention of steam formation, the further advantageous effect that any small air bubbles or air nests remaining in the fiber material are eliminated because the air bubbles are compressed and their adhesion on the fiber material is reduced so that they rise through the treatment liquid. This also leads to an improved effect of the treatment liquid on the fiber material.
  • the treatment liquid can expediently be given a pulsating movement during its action on the fiber material. This movement works in the sense of a concentration balance, in which the active ingredients diffused into the fiber material are replaced. Since such a pulsation of the treatment liquid, in particular if this is done using the vacuum pump assigned to the container (CH-PS 330 091), evaporation phenomena within the treatment liquid or the fiber material can occur, in this case the above-mentioned overpressure during the exposure time advantageous to exclude interfering evaporation processes with certainty.
  • the drying process is preferably also carried out in such a way that, after the treatment liquid has been removed from the container, air and / or steam first flows through the fiber material and thereby predried to a residual moisture content and then applying a vacuum while simultaneously applying heat the final moisture content is dried.
  • air and / or steam first flows through the fiber material and thereby predried to a residual moisture content and then applying a vacuum while simultaneously applying heat the final moisture content is dried.
  • predrying or mechanical dewatering by means of a flow through the fiber material the drying progresses comparatively quickly, but the residual moisture is then removed only slowly.
  • the vacuum pump is used to maintain the flow through the F a-sermaterials upright with air.
  • the pressure in the container reduced by the vacuum pump favors the evaporation process.
  • the residual moisture is essentially not evaporated but evaporated by the pressure drop brought about by the vacuum pump, drawn off in vapor form by the vacuum pump and deposited in the condenser. Since the vacuum acts essentially uniformly throughout the entire fiber material, the evaporation and thus drying takes place within the entire volume of the fiber material, which means the drying process accelerated and equalized, which in turn is in the interest of gentle treatment of the fiber material.
  • heat Since the residual moisture evaporates while removing heat of vaporization, heat must be added to the container or the fiber material during the final drying. This heat can be applied to the fiber material by radiation. Alternatively or additionally, high-frequency energy (microwaves) can be supplied to the fiber material during the final drying. It is also advantageous to alternately evaporate moisture from the fiber material by lowering the pressure and to heat the fiber material with the moisture still present in it by flowing hot air through it to compensate for the removal of heat of vaporization.

  • the chambers 27 and 28 are in flow communication with one another only through the perforations 14 of the carrier.
  • the fiber material 29 to be treated is wound up in layers on the carrier 13, and since the perforations 14 are only provided in the axial region covered by the fiber material 29, the flow connection between the chambers 27 and 28 runs through the fiber material only, except through the perforations 14 29 through.

  • a flushing water line 32 with a flushing valve 33 opens into the fiber material chamber 28 on the underside of the container.
  • An outlet line 34 with an outlet valve 35 is connected to the underside of the outlet chamber 27.
  • a vacuum pump 36 with an upstream condenser 37 is assigned to the treatment container 1.
  • the vacuum pump 36 is connected on the suction side via a suction line 38 and a four-way valve 39 on the one hand via line 40 with the valve 41 to the outlet chamber 27 and on the other hand via line 42 with the valve 43 to the fiber material chamber 28.
  • the vacuum pump 36 is optionally on the pressure side via a line 44 and a changeover valve 45 with a blow-out connection 46 or a return line 47 can be connected, which is also connected to the four-way valve 39 and can therefore be prevented alternating with the suction line 38 with the fiber material chamber 28 or the drain chamber 27.
  • a control unit 50 is provided to control the device, which can optionally also be carried out at least partially by hand. As indicated, this is connected via signal lines to a temperature sensor 51 in the treatment tank 1 and to a temperature sensor 52 in the storage tank 2 as well as to a liquid level sensor 53 and a pressure sensor 54 in the drain chamber 27. Furthermore, control lines emanate from the control unit 50, which for the sake of clarity are not shown for all the valves to be actuated but only for the valves 4 and 6.
