Definitions

  • the invention relates to a method according to the preamble of claim 1.
  • the starting point of the invention has been problems which have been pending for a long time in continuous dyeing with direct dyes (noun dyes) (see Fischer-Bobsien "International Lexicon textile finishing + border areas” 4th edition 1975, columns 419-422).
  • the dyeing liquor can be applied in a foulard, so that the web is passed through the larger amount of dyeing liquid in the pool of the foulard. This has resulted in unavoidable end processes, both at the beginning and at the end of the web.
  • parts of the fleet are towed out of the web, which cause a corresponding depletion of the fleet, which must be readjusted.
  • the invention is based on the object of designing a method in such a way that a uniform treatment failure occurs over the length of the web.
  • the method is primarily considered for the treatment of flat fabrics.
  • the first treatment liquor which is either the salt liquor or the color liquor, the other liquor following in the subsequent second step, is applied in some way and then squeezed to 60 to 120%.
  • the moisture values always relate to the amount of treatment liquor in relation to the dry weight of the web to which the treatment liquor has been applied.
  • a value of 120% is the upper limit of what can still be squeezed evenly in a squeezing device with interacting rollers; at higher moisture contents, the squeezing mechanism would have to be driven with line pressures so low that the uniformity of the squeezing would no longer be guaranteed and there would even be a risk of the rollers lifting off from one another in certain areas.
  • the second treatment liquor (color liquor or salt liquor, depending on what has been applied beforehand) is now applied to the web loaded with the specified amount of moisture, in a special way.
  • the material web should not be led through a larger fleet, in which there is a risk of concentration changes due to the amount of treatment agent carried out by the material web.
  • the second treatment fleet when the second treatment fleet is applied, the web should only be in contact with the smallest possible amount of liquor, which is very quickly absorbed and transported away by the web and which is accordingly constantly renewed or supplemented by introducing fresh treatment fleets.
  • Fresh liquor is therefore always applied to the web on both sides, through which no longer lengths of the web have yet passed. In this way, changes in concentration in the amount of treatment liquor in contact with the material web and corresponding differences in treatment failure can be minimized.
  • the second treatment liquor is not squeezed off after application. By squeezing, no total moisture content can be set evenly, which is significantly above 120%. If squeezed after the application of the second treatment fleet, it would at best be possible to add a few 10% of the second treatment fleet, which in many cases is too little for the interaction of the two treatment fleets and the failure of the treatment. For this reason, the web is stripped off after the second treatment liquor has been applied, so that the same amount of treatment liquid can be added in the order of magnitude as in the first application and total moisture contents can be achieved which are in the range of what the web can hold in terms of moisture at all without the moisture dripping from the web or runs down on it.
  • Such loads of liquor which have been pushed to the limits of the drip-free moisture content, are advantageous for many treatments, because this gives great water mobility on the web and the transport of the treatment agents between the two fleets and in particular the drawing up of the treatment agents from the entire fleet onto the fibers in the steaming step that generally follows the order.
  • a continuous process for dyeing a textile web in which it is provided with a first treatment liquor, partially dehumidified and then passed through an intermediate application unit with another treatment liquor, is known per se from DE-AS 10 78 527.
  • the known design is also out of the question for reasons of the required order quantities.
  • the gusset applicator comprises two rollers arranged at the same height, between which the web is passed from top to bottom, passing through the treatment liquor in the gusset between the rollers to a certain low height before it passes through the nip. Since the rollers have to seal the gusset downwards, they have to rest against each other with a certain line force, which inevitably means that the web is squeezed vigorously and higher order quantities are in principle not possible.
  • a preferred application example of the method according to the invention is the subject of claim 2.
  • Gusset application devices with which the application of the dyeing liquid from a small liquor stock and the subsequent stripping can be realized in a gap are known per se from FR-PS 13 81 081.
  • the invention does not lie in the gusset application device as such, but in the combination of an impregnation device with squeezing with an impregnation device with very little liquor content, in which subsequently stripped, ie a relatively large amount of liquor is left evenly on the web.
  • An application device with stripping is also apparent from DE-OS 20 36 520.
  • the web passes a container filled with treatment liquor, is deflected upward and passes through the gap between two horizontally opposite, rotatable, fixedly supported inflatable tubes, where the excess liquor is wiped off.
  • an embodiment of the invention is shown in the form of a device designated 100 as a whole for dyeing a flat fabric made of cotton with direct dyes.
  • the material web 1 is first passed through a padder 10 which forms the first application device and which comprises a plunge pool 2 which, with a width of the material web 1 of 1.80 m, comprises 30 to 60 l of a salt liquor 3, through which the material web in the manner shown is passed through a deflection roller 4, in order then to be directed vertically upwards and to be squeezed into the nip 5 between the nip rollers 6 and 7 to a moisture content of 70 to 90% by weight of the dry fabric web 1.
  • the material web loaded with this moisture is then deflected vertically downwards on a deflection roller 8 and thus passes into the gusset application device 20 which forms the second application device are essentially flat and slightly inclined to the web, ie approach it in the running direction.
  • the walls 11, 12 are connected to one another outside the edges of the material web 1, so that an upright, funnel-like trough 9 is formed, which can be filled with a treatment liquid 13 up to a selectable low fill level.
  • oblong recesses 15, 16 extending across the width of the material web are formed, in which inflatable pressure hoses 17, 18 are arranged.
  • the fabric web is slid through the gap 19 between the tubes 17, 18.
  • the treatment liquor 13, which in the exemplary embodiment is a dyeing liquor with direct dyes, received in the trough 9 is stripped down to a total moisture content determined by the pressure in the tubes 17, 18. This total moisture content is in the range of about 100 to 200%, i.e. the same amount of treatment liquor as that which has already been applied in the foulard 10 is added again in the gusset application device 20.
  • the level in the trough 9 is kept very low. With a web width of 1.80 m and the corresponding width of the trough 9 there are, for example, 4 to 8 l of the treatment liquor 13 in the trough 9. This amount would only suffice for a few meters of web 1 and would be used up very quickly. For this reason, the treatment liquor 13 is constantly supplied fresh by a feed device 14 and is kept in the trough 9 at a constant, albeit low, level. A significant change in the concentration of the treatment liquor 13 by treatment agents carried along by the material web 1 cannot therefore occur. Except for very small processes of the order of magnitude from 3 to 5 m, the entire length of the web 1 is colored evenly.
  • the material web 1 treated in this way now immediately moves into a damper 30 and then into a washing device 40 provided with several compartments.
  • a flat fabric made of cotton with a weight per unit area of 200 g / m 2 was provided in accordance with the prior art in a foulard without the addition of salt with the following dyeing liquor and then steamed in the steamer for 2 minutes: 3.0 ml / l Wetting agent 2.0 ml / l Blocking aids 1.0 g / l Oxidizing agent 0.5 ml / l ventilator 7.7 g / l Direct blue I 2.3 g / l Direct blue II
  • the fleet order was 85%, the working speed 30 m / min, the web width 1.8 m. The result was a blue-colored web with end drains of the order of 100 m, which had to be used for other purposes.
