Definitions

  • the invention relates to a dyeing pad for dyeing warp yarn, in particular cotton warp yarn, consisting of a dyeing tank for dye liquor and one or more squeezing units, rollers and / or deflecting rollers being provided in the dyeing tank for guiding the warp yarn sheet through the dyeing tank.
  • the well-known dyeing foulard - a container for dye liquor with a squeeze mechanism - consists of a simple roller skid, in which the chain to be colored is impregnated by being guided and deflected over several cylinders or rollers and / or deflection rollers which are under the fleet and is then squeezed off.
  • the length of the chain under the liquor and thus the dwell time of the chain in the dyeing liquor is determined by the number of sub-liquor rollers and deflection rollers mentioned and their spacing from one another. Since the dyeing speed is specified for indigo dyeing and is practically never changed, the immersion time is constant and only depends on the design of the dye container. However, the market is now demanding different color shades for indigo denim and also other colors.
  • the object of the invention is to provide a new dyeing pad which is suitable for dyeing warp yarns, in particular cotton warp yarns, both with indigo and alternatively with affine dye groups, in particular sulfur and vat dyes.
  • the contents of the dye liquor and the immersion time should each be changed in a simple manner, ie without the chain being pulled in and out as described above, in such a way that they are optimal for the respective dye group.
  • a liquor content is said of 800 to 1,000 liters and for dyeing with the other dye groups a liquor content of 150 to 300 liters is given, which liquor contents have proven themselves in practice.
  • the changeover from dyeing with indigo to dyeing with the other dye groups and vice versa should be quick and easy.
  • the dyeing pad according to the invention makes it possible, if desired, to dye chains of in particular cotton threads with indigo dye or with affine dye classes using the same device. This is of considerable advantage because such a dyeing pad meets the market requirements of delivering goods dyed with indigo as required, and another time as needed, for example supplying goods dyed with sulfur dyes. In particular ent Already about 10% of the "Blue Denim” market attracts attention to cotton goods dyed with sulfur black as "Black Denim". However, since the proportion of "black denim" is still less than that of "blue denim", it is not necessary to purchase a separate dyeing pad for dyeing "black denim".
  • the dye container By dividing the dye container into two sub-containers as chambers of the dye container, this can be used for both of the dyeing processes mentioned. Since there is only one dyeing tank with the two partial tanks, dyeing can be carried out in a smaller amount and with a smaller liquor.
  • the dyeing time is approximately halved for a given speed of the chain passing through the dye bath compared to dyeing with conventional dyeing pads, and the dyeing liquor required is reduced to approximately half of the liquor content previously required.
  • the displacement body By means of the displacement body, the volume of the partial container of the dye container required for dyeing with affine dye classes is reduced in a simple manner to the volume required for this, but the dye container is designed so that the displacement body can remain embedded in this partial container, even if with indigo -Dye, that is, with a larger liquor content of dye.
  • the changeover of the dye container from the setting for dyeing chains with indigo dye to the setting for dyeing with affine dye groups and vice versa is carried out in a simple manner essentially by changing (opening and / or closing) some valves in a very short time.
  • the dyeing pad according to the invention thus saves a separate dyeing pad for dyeing with affine dye groups, reduces dyeing time and required dye liquor content, avoids a feared dyeing error and also improves the dyeing quality. This also saves considerable costs compared to the dyeing pads of the prior art, so that dyeing can be carried out particularly economically with the dyeing pad according to the invention.
  • the dyeing tank 1 shows a dyeing trough 1 (dye container) that can be filled with dye liquor in a side view in a vertical longitudinal section.
  • the dyeing tank 1 is divided into two single or partial tanks 1a and 1b, between which, however, is connected in the upper region of the container 1 in that the mutually facing inner walls of the partial containers 1a and 1b run approximately horizontally on one another below the upper edge of the container 1 and below the surface of the largest liquor content and are connected to one another.
  • the distance of this connection to the liquor surface is determined on the one hand by the larger desired liquor content of the container 1 when dyeing with indigo and, on the other hand, by the smaller liquor content of the sub-container 1b when dyeing with sulfur or vat dyes, and by the fact that above this compound but below the surface of the Larger indigo dyeing liquor, two deflection rollers 2a and 2b are arranged for the chain K, by means of which the chain K is guided out of the first partial container 1a and into the second partial container 1b.
  • the dyeing container 1 thus has two chambers which are connected to one another in the upper region of the dyeing container 1, namely the partial containers 1a and 1b.
  • the total volume of the container 1 is designed so that it contains the larger dye liquor content during dyeing Indigo, in the embodiment of FIG. 1, can hold about 1,000 liters.
  • a roller (cylindrical body) 3a and 3b is arranged in each of the partial containers 1a and 1b in the lower region thereof, each at a distance from the container bottom.
  • a squeezing mechanism consisting of two deflecting rollers 4a and 4b arranged one above the other is shown essentially above the surface of the larger dyeing liquor.
  • a deflection roller 5 is arranged at a distance from it to the left.
  • the chain K coming from the top right in accordance with the drawing in FIG. 1 is first led into the partial container 1a, undercuts the roller 3a and is guided out of the partial container 1a via the deflection roller 2a; the chain K is then guided over the deflection roller 2b into the subcontainer 1b, runs under the roller 3b therein and is guided upwards out of the subcontainer 1b and to the squeezing mechanism 4a, 4b, by means of which excess dye is squeezed off the chain K, extends from here horizontally to the guide roller 5 and is carried away from this o 90 -Umschlingung upward.
  • the deflection rollers 2a and 2b have about half the diameter knife one of the rollers 3a, 3b, 4a and 4b.
  • the deflection roller 5 also has such a smaller diameter.
  • the dyeing container 1 has a total volume for a dyeing liquor of approximately 1,000 liters.
  • the partial containers 1a and 1b each have a basically the same volume for each holding about 600 liters of dye liquor, but for dyeing with sulfur or vat dye, for which only one dye liquor from 150 to 300 Liters is required, in the exemplary embodiment the partial container 1b is filled with dye liquor of only approx. 200 liters and therefore the desired dyeing liquor of approx. 200 liters is achieved in that from above the dye container 1 into the partial container 1b an internally hollow, closed displacement body 6 is let in with a volume of approx.
  • the displacement body 6 is preferably let into the center of the sub-container 1b at a distance from the roller 3b, towards which its underside is concavely curved, and in such a way that it will circulate at a distance from the chain K during its passage through the partial container 1b.
  • the displacement body 6 can be designed laterally (in the direction of the viewer of FIG. 1) up to approximately to the side walls 1 'and 1 Mahr of the dye container 1.
  • Its shape and size is therefore adapted to the inside of the sub-container 1b, but without hindering or interfering with the passage of the chain K through it and the dyeing process, and is otherwise determined by displacing about 400 liters of dyeing liquor through it. It is constantly in the sub-container 1b both for dyeing with indigo and for dyeing with sulfur or vat dyes, but can easily be moved out of the sub-container 1b and the dyeing container 1, for example for cleaning the dyeing container 1, via the guide rails (not shown).
  • Fig. 1 Shown in Fig. 1 are still attached to the outer walls of the partial container 1b heating coils 7 for dyeing with affine dye classes such as with sulfur dye, a feed tube 8 coming from above the dye container for the dyes, which in the embodiment of Fig. 1 is expediently above the Partial container 1b is arranged and its outlet opening is located above the (recessed) displacement body 6 and the surface of the displacement body 6 in this area may also have a bevel 6 'so that the dye does not deposit on it, if possible.
  • affine dye classes such as with sulfur dye
  • a circulation tube 9 below the partial tanks 1a and 1b, through which on the one hand a connection of the two partial tanks in their lower area can be established, so that when dyeing with indigo through this tube also dyeing liquor from one into the other partial tank 1a , 1b can circulate.
  • This tube 9 has a closable outlet 10 in the middle and a valve 11, with which dye liquor can be drained from the partial containers 1a and 1b or 1b.
  • both partial containers 1a and 1b and the (common) part of the dye container above are filled with dyeing liquor up to the deflection rollers 2a, 2b (LEVEL INDIGO ⁇ 1000 l in Fig. 1).
  • the hori the zontal distance between the entry of the chain into the dyeing liquor in the dyeing tank 1 and the next point on the surface below the axes of the deflecting rollers 4a, 4b in the exemplary embodiment shown in FIG. 1 in this case is 4.6 m.
  • Fig. 2 shows the dyeing tank 1 with side walls 1 'and 1 ⁇ in front view, ie dyeing tank 1 in the position rotated by 90 o compared to FIG. 1, with associated lines and containers in a vertical longitudinal section.
  • the width of the dyeing container 1 is determined by the width of the chains to be colored. Identical parts are designated in FIG. 2 with the same reference numbers as in FIG. 1.
  • the chain K and the deflection rollers and rollers 2a, 2b, 4a, 4b and 5 and the heating coils 7 are omitted in FIG. 2 for the sake of simplicity.
  • the dashed line 3b outlines the roller 3b lying behind the roller 3a in the partial container 1b.
  • the displacement body 6 is arranged above this.
  • the initially horizontally arriving feed tube 8 is shown, which bends at 8 by 90 o downwards and inside the dye container 1, below the surface of the dye liquor for dyeing with indigo, into a side inside on the side walls 1 'and 1 ⁇ of the dye container 1 attached and closed cross tube 8 'opens out, which is above the surface of the dyeing liquor for dyeing with sulfur or vat dyes and in the exemplary embodiment has four lower outlet openings 8a, 8b, 8c and 8d for the dye, which is distributed over the width of the partial container 1b are arranged. As illustrated in the case of the roller 3b in FIG.
  • this like all other rollers or deflection rollers running in the fleet, is preferably mounted outside, ie outside the dyeing container, so that the dyeing container 1 with its partial containers 1a and 1b forming its chambers, also without a fleet , ie without damaging the bearings, can be driven (internally stored rollers are "lubricated" by the fleet).
  • the circulation tube 9 In the bottom of the dye container 1, the circulation tube 9 can be seen, which has the outlet 10 and here has a valve 12. Over the tubular spout here 10, the dye liquor can be withdrawn from the dye container 1. At 13, a further circulation tube 13 enters the partial container (1b) above the bottom of the dyeing container 1, through which dye can be drawn off from the partial container 1b through openings 14a and 14b in the base of the partial container 1b.
  • 15 denotes a feed pipe for fresh water which opens into a circulation tank 16 for the indigo dye, which can hold about 200 liters of dye liquor.
  • a container 17 for hydrosulfite in powder form in a known composition is arranged, which, if necessary, is fed into the circulation container 16 when dyeing with indigo.
  • 18 a distribution pipe for the dye is referred to, which comes from a dye tank, not shown, and in the case of dyeing with indigo dye this feeds the circulation tank 16 via an intermediate tube 18 '.
  • the pump P in the feed pipe 8 the dye is fed to the dyeing tank 1 and the dyeing liquor is kept in circulation.
  • valves are designated.
  • the valve 19 in the intermediate tube 18 ' is open, so that from the distributor pipe 18 and through the intermediate pipe 18 'dye flows into the circulation tank 16, from which the dye flows below into another intermediate pipe 25 with the valve 21 open and from this into the feed pipe 8.
  • the valves 12, 20, 22 and 24 are closed in this case.
  • Dyeing liquor enters the further circulation pipe 13 from the dyeing tank 1 through the openings 14a and 14b in the bottom region of the dyeing tank 1 and, through this, returns to the circulation tank 16 when the valve 23 is open.
  • the circulation container 16 and the container 17 are inoperative.
  • valves 12, 19, 21 and 23 and 24 are closed while valves 20 and 22 are open.
  • the dye therefore flows from the dye tank, not shown, through the distributor pipe 18 into the unblocked part of the further intermediate pipe 25, from here through the feed pipe 8 in this case into the sub-tank 1b of the dyeing tank 1, again through the openings 14a and 14b in the further circulation pipe 13 dye liquor is withdrawn and through the further intermediate tube 26 with the valve 22 open in the Feed pipe 8 arrives.
  • the dye P is fed to the dyeing tank 1 or its partial tank 1b by means of the pump P and the dyeing liquor is kept in circulation.
  • the way of circulation of the dye i.e. Pumping out the dye liquor at the bottom of the partial containers 1a and 1b and feeding the dye liquor over the entire width of the partial container 1b ensure a perfect mixing of the dye liquor and thus also the perfect admixture of fresh dye liquor coming from the distributor pipe 18.
  • the dye liquor is dosed via the so-called.
  • a level controller is designated, by means of which the liquor level is regulated in the case of dyeing with indigo dye and in the case of dyeing with affine dye classes, and thus the respective liquor content in the dyeing container 1 or in the partial container 1b is kept constant.
  • the fleet level is kept constant by means of the level controller 27 with the addition of fresh Water from the feed pipe 15 for fresh water or from dye liquor from the distributor pipe 18.
  • dye liquor is always fed in and drawn off "under liquor", ie at the same desired liquor level, so that the chain to be colored during the dyeing process is at least or as little as possible Contact with air occurs and premature oxidation is excluded.
  • FIGS. 3 and 4 and 5 and 6 The foregoing is illustrated in FIGS. 3 and 4 and 5 and 6, FIGS. 3 and 5 corresponding to FIG. 1 and FIGS. 4 and 6 of FIG. 2 and the reference numbers being omitted for reasons of simplification.
  • affine dye here sulfur dye.
  • the dark fields also show the dyeing liquor and its circus lation, which is also illustrated by arrows. It follows that when dyeing with affine dye with "little liquor” and with “short circulation” (without circulation with the circulation container 16) dyeing.
  • 1 and 2 are designed for dyeing with indigo dye for a dye content of approx. 1,000 liters and the partial container 1b for dyeing with affine dye groups for a dye content of approx. 200 liters, but so far as far as dye content is concerned variations not shown in the drawing are possible.
  • the partial containers 1a, 1b can each have a volume of approximately 800 liters, together of approximately 1,600 liters of dye liquor.
  • a displacement body 6 can also be inserted into each of the partial containers 1a, 1b, each partial container then having a volume of approximately 600 or 400 liters, both partial containers 1a, 1b together having a volume of approximately 1,200 or 800 liters for receiving dye liquor .
  • the aforementioned three variants with a total volume of approximately 1,600, 1,200 and 800 liters are particularly suitable for dyeing with indigo dye, the variant with a total volume of approximately 1200 liters being used primarily for dyeing with indigo dye.
  • the first variant with a total volume of around 1,600 liters is particularly suitable for dyeing with indigo dyes, in which a high throughput of goods takes place at very high speeds with very heavy chains.
  • the variant with a total volume of about 800 liters is particularly suitable for dyeing with dye groups with low affinity, which require a longer immersion path to fix or better penetrate the dye onto or into the chain.
  • a variant is also conceivable in which only the partial container 1a without displacement body 6 is flooded as a dye container with dye liquor, the partial container 1a having a volume of about 600 liters. This variant is also suitable for dyeing with indigo dye.
  • a variant is also possible in which only the partial container 1b with displacement body 6 is flooded as a dye container with dye liquor, the partial container 1b having a volume of approximately 200 liters.
  • This variant is best suited for all dye groups except indigo dye because the mostly higher affinity of these dye groups requires a small liquor content in order to prevent a "head-to-tail" color flow.
