Definitions

  • the invention relates to a method for dyeing a textile web with the aid of a dyeing pad, in which a predetermined color distribution of the dry web is regulated by specifying a squeezing force distribution of the associated squeeze as a function of the colorimetrically measured color distribution of the web still having the initial moisture at the padding exit. It also relates to an apparatus for performing the method.
  • This direct color measurement known from DE-OS 39 25 444, of a fabric web at the padding exit ensures that any deviations in the color distribution from the target value are detected as soon as the fabric web emerges from the associated squeezer.
  • "Immediate" color measurement means that the respective color is measured as such - colorimetrically - and not the measurement of the web moisture is used for an indirect - arithmetical - determination of the color.
  • a major advantage of the known procedure is that the readjustment of the pad squeeze or the discontinuation of the coloring is carried out automatically, that is to say automatically by the machine.
  • Such an automatic system will generally only be designed or programmed for the usual types of fabric and color and their combinations.
  • color errors can occur, some of which only become apparent after drying or color fixing.
  • Such errors in the finished dried or fixed fabric web can also be caused in the area of the downstream drying or color fixing device.
  • the invention has for its object to improve the method mentioned in such a way that the eventualities of unusual combinations of fabric types and color types as well as possible color errors caused in the drying or color fixing device are automatically taken into account.
  • the invention is intended to create a device by means of which these problems can be solved.
  • the solution according to the invention for the method consists in that the color distribution, even of the dry fabric web, is automatically measured colorimetrically following a drying or color fixing device connected downstream of the foulard and is used alternatively to control the squeeze.
  • the automatic check according to the invention also of the dried or fixed web of fabric makes it possible to check the automatic system itself, so that the known control system can be learned to a certain extent by combinations of fabrics and / or colors and drying and / or fixing effects not previously provided in the program the device downstream of the foulard must be recorded and taken into account in the sense of producing a specific finishing of the treated fabric web.
  • a further embodiment of the invention is that the colorimetric measurement of the color distribution of the dry fabric web is used to correct the predetermination of the color distribution of the still wet fabric web. Additionally or alternatively, it can be advantageous to use the measurement of the color distribution of the dry fabric web to regulate the drying or fixing device connected downstream of the foulard in order to achieve a certain final equipment of the fabric web.
  • the invention is particularly important in solid dyeing because it is important here to exclude even the smallest color differences between the edge and center of the fabric and between the edges of the fabric. Accordingly, the color of the edge of the fabric is compared with the color of the middle of the fabric in the context of the present invention in solid dyeing; the color differences determined in this way are automatically eliminated by controlling the squeezing force distribution of the foulard.
  • the pad squeezer in the sense that here too the treatment intensity at the edges of the fabric web and the fabric web center is intervened in such a way that a certain condition of the final equipment of the fabric web also occurs is achieved when situations not envisaged in the previous program occur.
  • a particularly favorable device for carrying out the method is characterized by a single color measuring device comparing the color of the center and edges of the web both at the padding outlet after its squeezing and at the outlet of the downstream drying or color fixing device in control connection with the squeezer.
  • the use of a single color measuring device for all these tasks has the technological advantage that all measuring results come from the same device or measuring head, so that the measuring results can be compared without further ado, that is to say without any adjustments.
  • Another economic advantage is that the complex color measuring head is only required in one copy in each shelf.
  • a preferred embodiment of the direct color measurement in the above sense results if a fabric web guide is provided before and after the squeezing of the foulard, followed by a drying or color fixing device with fabric web sections running in parallel to measure the color distribution over a sufficiently long distance, if the color measuring device in the middle between the two web sections transversely to the web transport direction measuring head mounted and when the measuring head is pivoted by at least 180, such that it both the still wet web at the exit of the squeezer and the dry or fixed web at the exit of the dryer - or color fixing device is to be turned.
  • Such a measuring head can be automatically moved back and forth transversely to the direction of web transport and measure the color of the wet and dry web at short intervals at the measuring points by the measuring head at each measuring point once the still wet web section and once the already dried web section, which should have the same distance from the measuring head according to the invention.
  • a textile fabric web 1 e.g. made of woven, knitted or non-woven, passed through a guide roller 2 and an immersion roller 3 through a dye bath 5 belonging to a foulard 4. After emerging from the dyebath 5, the fabric web 1 arrives in a pinch designated 6 in total.
  • the fabric web 1 is mechanically dewatered by pressing the rollers 8 against one another in the direction of the arrows 9 to a moisture value which is referred to as initial moisture for the subsequent treatment.
  • the fabric web 1 after leaving the foulard 4 or the squeezer 6, runs past a colorimetric or color measuring device 10 and past a moisture measuring device 11 via a guide roller 12 into a hot flue 13 or the like drying or color fixing device, e.g. Thermosol plant.
  • the drying or ink fixing device can also be a tenter, for example.
  • the color measuring device 10 and the moisture measuring device 11 can also be arranged side by side or in reverse order.
  • the fabric web 1 When the fabric web 1 has passed through the drying or ink-fixing device referred to in the exemplary embodiment as hot flue 12, it is guided via a deflection roller 14 to a pair of rollers, between whose individual rollers 15 a (dry / fixed) fabric web section 16 parallel to a (still moist) fabric web section 17 of the area between crushing unit 6 and hot flue 13.
  • the colorimeter 10 In the middle between the two fabric sections 16 and 17, the colorimeter 10 is arranged and stored according to the invention so that it can be moved on a line 17 transversely to the direction of transport 18 of the fabric (and parallel to its surface in the area of sections 16 and 17) can also be pivoted about an axis 20 oriented perpendicular to a common normal 19 of the sections 16 and 17.
  • the mutual distance A of the sections 16 and 17 is essentially set according to the requirements of the measuring head 21 of the color measuring device 10. It is important for the comparability of the measurement results that the distance a between the respective position of the measuring head 21 of the color measuring device 10 and the section 16 or 17 of the fabric web 1 is the same in the two measuring positions of the measuring head 21.
  • the evaluation of the measurement results of the moisture measuring device 11 takes place in a manner similar to that specified in DE-OS 39 25 444.
  • the color depth and a difference in the measurement results for the left edge and the right edge relative to the center of the fabric web are measured in the direct color measurement according to the invention, that is, the measurement results at the fabric web edges are compared with the measurement result of the fabric web center .
  • the difference of the invention compared to the known from DE-OS 39 25 444 lies primarily in the fact that not only measurement results of the still wet web of material following the foulard 4 or the squeezer 6, but also of the dry web of material subsequently the hot flue 13 or the like can be made. Since the color measurement is carried out in both cases with one and the same measuring head 21 under the same conditions, all measurement results must be compared immediately, so that additional errors, for example as a result of different aging of different measuring devices, cannot occur.
  • This double use of one and the same measuring device becomes possible if it is possible to feed the web guide before and after drying or fixing in two essentially parallel sections 16 and 17 on both sides of a pivotable color measuring device 10 or measuring head 21. In this way, one can Check the same spot on a fabric before and after drying or fixing with one and the same colorimeter. The color of the corresponding fabric spot can therefore be determined directly before and after drying or fixing in a completely identical manner.
  • the results recorded with the measuring head 21 can be fed to a computer 23 along the line of action 22.
  • the results recorded with the moisture meter 11 along the line of action 24 can also be sent to the computer 23.
  • the computer 23 can then be used according to its program or the changed program to control the squeeze mechanism 6 along the effective line 25.
