Continuous process for the treatment of textiles in Strangfoxm.

The present invention relates to an improved one Method and device for the continuous and successive treatment of textiles, in particular in strand form in various liquid baths, such as dyeing, washing, desizing, bleaching and the like.

So far, the continuous treatment of Textiles the material in the entire width one after the other through several large containers with the appropriate treatments. Obligations led. These containers were old complicated drive devices and guide means !! provided, including all of the material across its entire width to lead through the container. This «plants work

ala open systems and without overpressure, as the use special seals at the feed openings for the Textile material fed in over the entire width of the one in the other individual container causes difficulties. Because the textiles stay long enough in each container In order to ensure adequate fluid treatment, it was necessary to be deformedly large Container to use; on the one hand the width of the textile web and on the other hand the corresponding length of the textile web had to be must be taken into account so that the material could remain in the liquid for a long enough time. This continuously working systems require considerable expansion and require large amounts of bath fluid, which in turn is a poor use of the bathroom Chemicals conditional. For these reasons, these continuous systems are extremely uneconomical.

Bs are also individually · devices for batchwise Treatment of textiles known, which take up less space and save on handling equipment. Such Devices according to US Pat. No. 2,978,291 enable intermittent work in which the substances in the bath, e.g. dyes, are completely absorbed and thus added according to the amount of textiles to be treated. With such a device

the textile material in strand form and not in its whole Width treated «with the ends of the web together are sewn »so that you get an endless strand. This strand is then formed as a ring by jets of fluids in a narrow way above the treatment liquid circulates. These jets of liquid are generated by circulating the treatment liquid in the tank. Obgleioh this device has some advantages over the continuous process with dera Durchlei th of the textile web has in full width through several containers and the treatment liquid better utilized and less space is used for the device in question, however, the length of time for the treatment of the textile! .materials is not significantly improved, since one must use numerous such devices when the textiles with different Liquids to be treated; also need these known devices separate supply and discharge organs for the individual units.

The present invention has now set itself the task of an improved method and apparatus for the continuous treatment of textile in rope form To propose in several treatment areas, whereby the Working speed with lower labor costs and less space is increased than before. Further

the advantages of previous absatzwoisen work ^ and those of the continuous treatment with liquids are to be combined. Furthermore, when working continuously, the textile material should be passed through several different baths, some of which can also be under elevated pressure or under elevated temperature or at normal pressure and lower temperatures. According to the invention, a continuous treatment for desizing textiles with enzymes is to be made possible, with means being provided so that the foam produced by the saponification of waxes and fats is reduced and the system is prevented from being switched off due to the pumping out of the circulating fluid. Furthermore, the present invention aims to provide a device in which a jet of liquid moves the textile rope through the device, with the device still having means to support the further movement of the textile rope and to increase the difference in the weight of the fabric at the interfaces with the liquid Compensate "So far as the present invention, a device is to be proposed in which improved means are provided in order to allow the textile region to be folded over in the liquid when it is folded or in order, and to prevent the further conveyed textile range from getting tangled.

In the case of continuous treatment of the Textile material in strand form, the bath temperature and thus the pressure increases, under which the textile material continuously is transported through the various baths * This can be made possible if the treatment liquid gives optimal results under these conditions.

An essential feature of the present invention is that it allows continuous liquid treatment of textiles in strand form one after the other through several baths, whereby the material is open and not as a closed ring with ends sewn together and thus continuously transported or transported as an endless ring into a bath in question . is enjoyed out of this. This extremely advantageous method of handling Textillen in strand form reduces the Behandlungsxeit considerably as nan not the ends to a ring sewing ma3 and separating again after the treatment in the liquid in question this interface and then zusamnennfihen for the next treatment in another liquid again oufi . In addition, the continuous Arbeltswelse results in a similar treatment of the textile strand within the relevant liquid, for example in a dye bath, as all areas

Pig. 2 z-sigt that the AusJaßkaimner is slightly larger than the inlet chamber, which will be explained later in connection with the measuring roller 24. The covers 20 and 22 at the inlet and outlet points 16 and 18 are provided on each container 10, 12 and 14, so that in the following only a single container is described.

In front of the first J-shaped container 10 is a Loading container 26 with a NetzflUsslgkeit WL which reaches up to the liquid level N. The textile material T is fed in the form of a strand into the hopper 26 in relaxed state through a suitable opening 28 and then down over a roller 30 into the liquid WL and then guided upwards over a second roller 32, which is arranged below the liquid level and close to the bottom of the container. The textile material T is fed in strand form through the hopper 26 in Direction of arrow guided. In the upper area of the feed container 26 is a measuring roller above the liquid level or feed roller 24 is provided, for example from can consist of three single rollers. These feed rollers 24 are via a chain wheel 34 by means of an electric motor 36, which can circulate at different speeds,

Furthermore, the tube 48 can be a heat exchanger 54 with a steam outlet 56 and a steam outlet 58. If you want to heat the liquid in the container 10, then steam is introduced through the heat exchanger 54 if the liquid is forced from the container 10 through the pipe 48 into the fitting 38 and the line 40. By Suitable thermostatic * control devices can be the liquid L in the container 10 at the desired temperature left. Since the container IO is completely closed, the pressure is also created by heating the liquid L increased in the container. However, if this is not desired, there may be drain valves at the top of the container be opened.

The loading container 26 serves primarily one dual purpose. Once he closes the system if it is under pressure, he enables it to end from time to time an even wetting of the textiles «the subsequent are treated in the various treatment tanks 10, 12 and 14; finally-it serves as a feed chamber, in which the textile strand is the first in a relaxed direction Zuntfiwalsen 24 and the first nozzle assembly 38 supplied will. · The U- or J-shaped containers 10 «12 and 14 are

An alternating jet nozzle is provided at the inlet chamber 16 jet which delivers the liquid under high pressure and preferably the liquid L in the container, for example by connecting the nozzle to the outlet side of the pump, so that part of the liquid conveyed by this pump P is supplied to the nozzle 60 flows w while the other part through the heat exchanger 5 ¹ V in the valve 38 is passed. As shown in FIG. 2, the tube 44 reaching through the cover plate 20 of the container 10 is angled at the outlet end at 62, so that the textile material is guided in the direction of the container wall when it exits. The nozzle 60 arranged just below this outlet end 62 is directed downwards and angled in the opposite direction so that the liquid emerging from this nozzle occurs on the textile material in such a way that it is guided in the opposite direction to the other wall side of the chamber, whereby the textile strand ordentlioh is folded or stacked when it is directed downwards en & bent portion of the container lower IO transport.

Xn of the inlet chamber 16 of the container 10 are two opposed perforated grids 64 and 66 which connect the SInIaB to the part of the container containing the liquid · Because the textile material has a semicircular shape

an exit arrangement 78 (pot eye) is provided through which peeled off the textile web and, if necessary, usable a drying device can be withdrawn and then wound up at 82.

Of course, several treatment tanks, however, at least two can be provided. If the textile material in four ode? five liquids are treated should, of which some are different from each other, can of course four or five containers in the described Catfish are connected to each other. In some cases, you can have up to twelve or more containers in a row be switched, some with the same treatment flow have »if according to the relevant a longer residence time is required for the treatment procedure 1st.

Each of the containers 10, 12 and 1 * is equipped with an ultrasonic generator Bk , which is operated pneumatically by steam supplied via the line 86. The arrangement of these ultrasonic generators above the liquid level "in the containers is intended to reduce the formation of foam in these containers" and not to switch off the system due to irregular loads on the pump.
