Definitions

  • the present invention relates to a method and a device for the continuous, even application of aqueous impregnation liquors containing at least one treatment agent to water-wet, textile webs, which, coming from a previous wet treatment, have been partially dewatered evenly in a first dewatering step to a certain residual moisture content, the continuously moving, moist material web without intermediate drying within an impregnation trough when diving below the liquid level in a spread form is passed over a liquor application element and the predetermined amount of liquor is absorbed by the material web by its moisture content in the longitudinal and transverse directions to the material flow by means of an alternative arrangement more than two measuring points across the web width after the first dewatering stage before the fleet application and by means of an additional measuring arrangement of this type after the fleet application g and determined continuously and without contact after a second dewatering stage, and in accordance therewith the moisture content after the second dewatering stage is set such that it is higher than after the first dewatering stage.
  • perforated drums can be used to apply liquid agents, which drums are arranged in an immersion bath and over which the spread material web is guided during the passage through the fleet. Due to the suction suction exerted on the textile material, better penetration of the fiber material with the treatment liquid is thus ensured.
  • it is strictly a one-time fleet order, which is either not critical with regard to the order quantity or is followed by squeezing off by padder or other suitable drainage systems in order to obtain a specific order quantity.
  • the object of the present invention is now to get a handle on the continuous dyeing of a uniformly wet textile material on an industrial scale and with safe handling of the various treatment phases, with the aim being to achieve optimum dyeing of the goods without the risk of the end of the process dyed textile plays a role.
  • Such a project has also received new impetus from the energy saving program.
  • the principle of the present invention is based on checking the moisture that is necessarily introduced into the application process of the treatment agent on the wet substrate and then displacing it in the course of a passage of circulated impregnation liquor through the web of material passed directly past the exchange element and at the same time adding impregnation liquid containing the treatment agent replace, whereby the exchanged moisture from the pretreatment is absorbed in the circuit of the impregnation liquor.
  • the risk of a progressively increasing liquor dilution is avoided by the measure according to the invention of the constant addition of freshly prepared liquor replenishments, which ensure that the concentration of the treatment agent is kept constant and also compensate liquor losses as a result of the correspondingly higher proportioned amount applied in the second stage.
  • EP-A 49441 is not a method in which a fleet exchange takes place between the fleet quantity introduced and the newly applied fleet quantity by means of a fleet exchange element, but only an additional fleet is applied to the wet one Applied goods that mix in the goods with the existing moisture.
  • a fleet exchange inevitably entails a dilution of the fleet, which is avoided by the measures of this prior art.
  • a real fleet exchange is forced and therefore measures to keep the concentration conditions constant must also be taken.
  • a device suitable for carrying out the novel wet-on-wet application process, to which the present invention also relates essentially consists, as shown in the drawing, of two drainage elements (2a, 2a, one behind the other in the running direction of the textile material and effective across the web width).
  • the textile material (1) squeezed to a uniform moisture in a first dewatering member (2a) is passed through a liquor exchange element (5), for example a sieve drum or a suction slit, in the course of the further transport of the goods which is immersed in the impregnation liquor containing the treatment agent.
  • a liquor exchange element (5) for example a sieve drum or a suction slit
  • the circulated impregnation liquor is sucked through the spread textile material under the action of a pump (7), exchanging or diluting with the residual moisture on the goods, and then conveying it in a kind of cycle to the actual impregnation trough (4) upstream in the direction of flow distribution chassis (10), which is equipped with mechanically effective means (9) for fleet mixing and their even distribution within this facility, with particular attention to the width of the web to be treated.
  • the circulated impregnation liquor then arrives at the subsequent impregnation trough (4) and is evenly distributed again by means of an overflow (11) extending over the same width there, as before with the passage of the goods via (5), through the exposed textile material sucked in by the pump (7), which also ensures the circulation of the fleet at the same time.
  • the impregnation liquor can also be pressed through the goods for the purpose of liquor exchange if the liquor exchange element (5) consists of a screen drum which is pressurized from the outside and the impregnation trough (4) is provided with a pressure-tight web inlet and web outlet. It is advisable to work with excess flows of the impregnation liquor through the textile web (fleet throughput).
  • the textile goods treated in this way are then squeezed, sucked off or stripped off evenly to the desired liquor intake in a second dewatering device (2b), but while maintaining a higher level of moisture than before entering the impregnation bath, and are then passed on to the further fixing process.
  • the normalization of the moisture already on the textile material can be carried out using a normal high-performance squeeze mechanism, advantageously a foulard.
  • a normal high-performance squeeze mechanism advantageously a foulard.
  • the tissue moisture is measured continuously and lengthways on the fiber material guided at a constant speed and the measured values thus obtained are used for control the drainage performance at the corresponding points on the web.
  • the moisture measurement itself is carried out in a contactless manner using well-known methods, for example with the aid of a moisture measuring device based on the principle of microwave absorption, as described in DE-U 7 638 683. In this way, the amount of water in g / m 2 can be determined, which is introduced into the impregnation bath by the goods.
  • the squeezing after the impregnation is monitored by means of a measuring arrangement (3b) connected downstream of the corresponding dewatering device (2b) and having the same equipment as before, and is thus able to continuously perform the desired control function for the fleet application.
  • the consumption of the impregnation liquor is then derived from the difference between the two moisture measurements.
  • the amount of moisture in relation to the second measurement is kept larger at (3b) than in the case of the first measurement (drainage) at (3a).
  • the circulatory system described above before the used impregnation liquor enters the distribution chassis (10) upstream of the impregnation trough (4), is metered in with as much freshly prepared liquor replenishments of a correspondingly higher concentration of the treatment agent as the fleet difference after the first and second drainage. It is thus possible to counteract the reduced concentration of the impregnation liquor in the treatment agent as a result of liquor dilution, caused by the moisture exchanged and introduced into the circuit, and to remedy the reduction in the liquor volume resulting from excess liquor uptake by the goods.
  • the measures required for this can be done in such a way that a freshly prepared liquor additive or several of different compositions are mixed in parallel and synchronously with the used circulation liquor or that - depending on the requirements to be taken into account - a freshly prepared liquor additive is first added to it and then in the direction of flow of the liquor cycle after a sufficient mixing section, one or more further such liquor replenishers of the same or different composition are metered into it.
  • the sequence of the method according to the invention can expediently be controlled via a control device (13) such as a process computer, by relating the known or measured process parameters (actual value) to the setpoint (for example the specified fleet order) and converting them into control signals (manipulated variable). Due to such a process, the fleet difference values continuously determined by the two measuring points (3a) and (3b) can advantageously be used to control the performance of the circulation pump (7), i.e. the number of circulations of the impregnation liquor in the time unit and / or the performance of the metering pump (8), that is of the dosing quantities.
  • a control device (13) such as a process computer
  • the performance of the metering pump can also be controlled by means of a level controller (not shown) for the fleet in the impregnation trough (4).
  • a level controller not shown
  • the control of the speed of the goods is provided as a function of the squeezing pressure of the two drainage elements (2a) and (2b).
  • the present invention a very good exchange of the moisture carried in by the wet goods for the impregnation liquor containing the treatment agent is achieved. Due to the circulation of the liquor, the same concentration of impregnating agents is always available for the application process. The penetration of the goods through the liquor ensures an equal distribution of the same across the cross-section of the textile web and the metering of fresh liquor preparations into the circulation takes into account that the fiber material is treated at the same end.
  • the device according to the invention is explained in more detail with reference to a drawing.
  • the figure shown shows a schematic representation of the side view of a continuous line, according to which a screen drum is provided for the liquor exchange according to the suction principle.
  • the reference symbols used here are identical to the numbers used for this purpose in the text above.
  • the new impregnation process is suitable for practically all finishing processes, e.g. Mercerizing, dyeing, applying all finishing chemicals such as finishing agents, antistatic agents or finishing agents, etc.
  • all classes of dyestuff, but also other finishing agents can be applied to textile webs of all fiber materials suitable for continuous operation.
  • the wet textile material can be woven, knitted, felt, fleece, parallel yarn, cable or sliver and consist of textile fibers of any kind.
  • the applied treatment agents are then fixed or developed according to the usual working methods for the products concerned, e.g. by simple storage at room temperature or vapors or hot air treatment and other methods. The claimed method is therefore not subject to any reservations in this regard.
  • the order fleets can use all the necessary aids such as Alkalis, acids, leveling agents, solubilizers, etc. also without restriction - except where appropriate their solubility and ionicity - are added.
