Definitions

  • the invention relates to methods and devices for treating, in particular drying, shrinking and finishing, textile webs according to the preamble of claims 1 and 5, respectively.
  • Such a method and a device suitable for carrying it out are known from DE-A-23 01 938.
  • the web of material lying on an air-permeable screen belt is successively passed through three drying zones.
  • blowing nozzles are arranged above the web and suction nozzles below the sieve belt.
  • the blowing and suction air jets press the web onto the sieve belt, where it is fixed practically immobile.
  • blowing nozzles are arranged both above and below the sieve belt, which lift the web off the sieve belt.
  • the movement and shrinking processes associated with the drying process can only take place in this zone. However, these movements and shrinking processes are minimal, since practically no dynamic forces are exerted on the web. This type of dryer has therefore not become established in practice.
  • the drying performance is low. Since the air always takes the path of least resistance, it essentially only sweeps over the surface of the goods and only absorbs surface moisture there. The moisture in the depth of the fabric is only removed when it reaches the surface through diffusion and capillary action. Whether and how much of the inflated air flows through the web depends on the distance between the blowing nozzle and the web and on the current air permeability of the web, which in turn is an inverse function of the residual moisture.
  • a dryer is also already known from BE-A-75 23 12, the conveyor belts of which are set in vibration with rotating vibrators in order to enable the shrinking of the textile material webs.
  • the machine with the best drying performance is currently the sieve drum.
  • the material web is forced to flow through from the outside in.
  • the web is firmly fixed on the drum and can only lift off again when the air flow stops and the transition to the next drum or to the machine outlet is released. Since the web is not allowed the slightest freedom of movement, it leaves the screening drum in the same Dimensions with which it was run in.
  • the shrinkage potential inherent in the web is therefore not reduced. Rather, a separate shrinking process has to be carried out afterwards, since goods that fall by 15 to 20% during the first wash are no longer salable today.
  • DE-PS 964 948 a device for tension-free drying of textile material webs is known.
  • the web is guided on an upper conveyor belt in the manner of a hanging loop dryer.
  • the web loops themselves lie on a lower carrying belt.
  • the distance between the upper and the lower carrying strap can be changed.
  • the material web is blown from above with air of low pressure, from below with air of high pressure.
  • the object of the present invention is to improve the method known from DE-A-2 301 938 and the device suitable for carrying it out in such a way that excellent drying performance is achieved with excellent shrinking performance.
  • the aeration known from the drum dryer is connected with the free and tension-free movement of the web as well as with the mechanical processing of the web.
  • suction nozzles opposite the blowing nozzles, the material web is drawn directly in front of the suction slot of the suction nozzles; Therefore, the air has no choice but to flow through the goods and also carry away the moisture sitting in the depth. This effect is optimal if each blowing nozzle is opposite a suction nozzle, the blowing or suction direction being directed essentially perpendicular to the plane of the conveyor belts.
  • the web takes on the well-known sinus shape under the action of the blowing and suction nozzles. If the shaft tips hit conveyor belts, some of the relaxation forces are brought into the web. At the same time, the web is fixed so far that it is transported perfectly straight and does not run away to the side. Since the shaft tips are constantly shifting, the material web is freely movable in both the longitudinal and the width direction, so that the material can shrink.
  • the rest of the relaxation forces are preferably transmitted to the shaft tips lying there by vibrations of at least one of the conveyor belts. Since the web does not rest on the conveyor belt as a whole, but only with the shaft tips, its resonance frequency is hardly influenced by the weight of the goods; The values of band and nozzle spacing or vibration frequency that have been set do not need to be adjusted.
  • Another advantage of the invention is that it is not only possible to dry and shrink with optimum performance, but also that the goods can be optimally equipped. With plush, the handles are raised perfectly, with terry goods a volume is reached, as otherwise only the tumbler brings, crease effects can be created, etc.
  • the air quantity of the blowing nozzles is set higher than the air quantity that is sucked through the fabric web by the opposite suction nozzle.
  • blowing and suction air can advantageously also be set according to the moisture saturation of the drying air.
  • the saturated exhaust air is removed from the system and replaced by an appropriate amount of fresh air.
  • the speed of the conveyor belts does not have to remain constant. Rather, it is preferably changed as dictated by the progressive shrinking process.
  • the principle of aeration according to the invention by means of suction nozzles brings about an enormous increase in the drying capacity, which makes it possible to drastically reduce the dimensions of the system with the same drying capacity compared to the dimensions of known systems.
  • the cross section of the blowing and suction nozzles is conical in order to achieve a constant air speed and a constant exit angle over the length of the nozzle gap, which can reach up to 2.5 m.
  • the height remains of the nozzles constant, so that a low overall height is achieved.
  • Modules which can be combined with one another are advantageously formed from a number of suction and blowing nozzles and vibrators, so that the finished systems can be adapted in a simple manner to the performance required by the customer.
  • Fig. 1 shows a schematic, perspective view of a device for drying, shrinking and finishing textile webs. It essentially consists of three basic elements, the goods inlet, the dryer and the goods take-off.
  • the material web 20 delivered in a mobile transport container 10 is transported via a material web guide 30 with a conveyor belt 31 into the inlet chamber 41 of the dryer 40.
  • the dryer 40 consists of six three-tier modules 40.1 ... 40.6. A total of four endless conveyor belts 43.1 ... 43.4 run through the modules 40.1 ... 40.6.
  • the web 20 runs with a corresponding advance between the lower run of the upper conveyor belt 43.1 and the upper run of the adjacent lower conveyor belt 43.2. Above the lower run and below the upper run, two blowing nozzles 47 and two suction nozzles 48 are alternately arranged in each module, so that one suction nozzle 48 is opposite each blowing nozzle 47. Under the action of the blowing and suction nozzles 47, 48, the web 20 is given the well-known sine wave shape, the wave tips each striking the conveyor belts 43.1 ... 43.4.
  • transfer belts 44 or transfer chutes 45 are arranged there.
  • the belt gap and the nozzle distance, the transport speed and the Vibration frequency can be set continuously.
  • the high drying capacity is made possible by the fact that the drying air has to flow through the web due to the arrangement of each suction nozzle in relation to a blowing nozzle and thereby also tears out moisture that is stuck in the deeper layers of the web.
  • the fabric 20 leaves the outlet of the dryer 40 via a fabric take-off 50 with an outlet conveyor belt 51, it also being possible, if appropriate, to provide a cooling fan and a paneling device.
  • FIG. 2 shows, on an enlarged scale, a section of the device of FIG. 1 in the area of the blowing and suction nozzles 47, 48.
  • the two parallel conveyor belts 43.1, 43.2 on which the web 20 is transported lying loosely can be seen.
  • the mouthpieces 47.1, 48.1 of the blowing nozzles 47 and suction nozzles 48 directly adjoin the rear of the conveyor belts 43.1, 43.2 and are specially shaped to allow the conveyor belts 43.1, 43.2 to pass smoothly.
  • the web 20 is carried without tension by the air currents.
  • the wave valleys and wave peaks shift according to the transport speed of the conveyor belts 43 so that all parts of the web 20 are dried and shrunk intensively.
  • the distance D between the conveyor belts 43.1, 43.2 and correspondingly the distance between the mouthpieces 47.1, 48.1 of the blowing and suction nozzles 47, 48 can be changed in order to enable an optimal adaptation to the properties of the web 20.
  • FIG. 3 and 4 show an enlarged representation of two embodiments of vibrators 49, with the aid of which the conveyor belts 43 can be set in vibration.
  • These are oscillating cylinders 490 - hydraulic or pneumatic - which are mounted on the housing of the dryer 40.
  • the cylinders 490 move oscillating lifting rods 491, to which two-armed levers 493 are articulated by means of rotary joints 492.
  • the two-armed lever 493 are with the help of Bearings 494 mounted on the housing of the dryer 40.
  • the free ends of the two-armed levers 493 carry an impact strip 495, each of which sets the lower conveyor belt 43.3, 43.4 or the upper conveyor belt 43.1, 43.2 in vibration.
  • the lower and upper conveyor belts 43.1, 43.2, 43.3 can also be vibrated together if the resonance frequencies match.
  • blow rollers 496 can be rotatably mounted on the blow bars 495.
  • rotating camshafts can also be used, as shown in FIG. 1 in the area of the lowest conveyor belt 43.4.
