Definitions

  • the invention relates to a method for treating an endless fiber cable in an apparatus into which it is inserted, in which it is crimped and treated with a gas and from which it is discharged.
  • Different types of endless fiber cables have to be subjected to drying, relaxing or heat setting steps, especially after washing, stretching or finishing in order to obtain a desired moisture content and certain values for properties such as elongation, strength or dyeability.
  • such fiber cables are usually crimped in order to prevent the fiber cable from falling apart into individual threads and, as a cutting fiber, to have sufficient adhesion for the subsequent spinning process.
  • the drying, relaxing and heat-setting steps are usually carried out by treating the fiber cable with a gas, in particular with steam or heated air. Certain dwell times must be observed for these steaming and drying processes.
  • the low-tension, mostly tension-free placement on the sieve belt has the disadvantage that product layers of the folded cable that have been deposited first come to lie down and are always covered by product layers that are deposited later, so that when the cable is pulled off the screen belt, a large part of the cable must be pulled away from under the remaining cable. This can lead to confusion, matting and thus disruption of the process.
  • the cable In order to remedy this disadvantage, the cable must be placed on so-called reversing drums before insertion into the steaming or drying apparatus, which ensure that the product layers first deposited come to lie on the sieve belt and can be pulled off properly.
  • a disadvantage of this complicated technique is that the device is difficult to seal on the product inlet side, so that large amounts of air are unnecessarily introduced into the device and heated up, or harmful emissions occur at the leaks. Furthermore, the reversing drum causes the cable to cool down, and thus energy loss.
  • the object of the invention is to arrive at speeds of 100 to 2,000 m / min fiber cables with strip weights of 5 to 500 ktex with low energy and emissions. curl and steam or relax or dry and fix.
  • This object is achieved in that the cable via a gas dynamically operated, in the end wall of an apparatus for treating the cable with a gas assembled crimping device crimped and thus introduced into this apparatus in a lock-like manner, paneled over a slide with an S-shaped profile as crimping cake onto a gas-permeable, horizontally transporting base, treated there with the gas and finally carried out from the apparatus.
  • the blow nozzle can be operated with steam or appropriately tempered air.
  • the end wall in which it is mounted can at the same time be the end wall of a previous device, in which washing, stretching or finishing is carried out, for example.
  • the gas treatment apparatus can be divided into several treatment zones. In the individual treatment zones, the steam or air treatment medium is circulated by a fan via a heat exchanger and the product is circulated. In the case of cooling zones, heat exchangers are dispensed with and fresh air is used for cooling. If the apparatus is used as a dryer, a fresh air stream is superimposed on the internal circuits in counterflow to the product. This fresh air flow cools the product in the cooling zones and heats up at the same time. In parkour through the dryer, it charges with the moisture removed from the product and is drawn off in the first dryer zone with the help of a fan. If the apparatus is operated as a damper, the crimping nozzle is also expediently operated with steam.
  • the ruffled steam can then be used for steaming at the same time, but must then be conducted to the product in cocurrent. In conclusion, here too chilled.
  • the apparatus can also be used for the combined steaming and drying treatment, an intermediate zone being expediently inserted between the steaming and drying zones. At the end of the apparatus there is an opening through which the cable is led out of the apparatus and optionally fed to a further device, for example a cutting or a paneling device.
  • the horizontally transporting support can be a screen belt, which is completely included in the apparatus housing at least up to the withdrawal zone.
  • the horizontally transporting support can also be a vibratory conveyor to which the slide with an S-shaped profile can be attached directly.
  • the slide then swings with the vibrating conveyor.
  • the stretched fiber sliver is converted into a compressed, round, oval or square cake pan.
  • the compression factor defined as the ratio of the sliver speed to the cake speed, is in the range from 2 to 25.
  • a paneling factor is also defined as the ratio of the cake speed to the conveying speed of the transporting base. This is 1 to 100.
  • conveyor speeds of 0.5 to 5 m / min can be realized and thus relatively small apparatus with long dwell times of, for example, 2 to 15 minutes.
  • the upsetting and paneling make it possible to achieve covering densities of 1.5 to 20 kg / m 2 . This enables gentle and very even treatments with low gas velocities of 0.3 to 3 m / sec.
  • the curling tape cake is neatly paneled onto the horizontally transporting base when the S-shaped chute has an inclination to the horizontal of 30 to 70 °, predominantly 45 to 60 ° and a transition radius at the upper and lower end of 50 to 200 mm, preferably 75 to 150 mm.
  • the slide is arranged above the parabola of the curling material.
  • the gaseous medium preferably steam or hot air, can flow from bottom to top or from top to bottom through the gas-permeable, horizontally transporting base and the curling belt cake.
  • the method according to the invention is suitable in principle for all endless fiber cables, but in particular for those which have been produced by spinning a spinning solution.
  • the method according to the invention for treating acrylic fiber cables is particularly effective, preferably produced by the dry spinning method.
  • the product 1 shows a longitudinal section of a device in which the method according to the invention can be carried out.
  • the product 1 is introduced into the apparatus through a gas dynamic crimping device 2, which is mounted in a gas-tight manner in the end face 3 of the insulating housing 4.
  • a gas dynamic crimping device 2 which is mounted in a gas-tight manner in the end face 3 of the insulating housing 4.
  • the crimp belt cake is paneled onto a sieve belt 7 integrated in the apparatus in such a way that it can be removed properly after the treatment.
  • Fresh air is drawn in through the product outlet opening (not shown) and blown onto the product by the fan 8 via the heat exchanger 9. Exhaust air is discharged via line 10 and fan 11 and an adjustable flap (not shown).
  • Fig. 2 shows a longitudinal section through a conventional and known belt dryer.
  • the product 1 is paneled onto the turning drum 13 with the aid of the traversing device 12, which is movable in a vertical plane transverse to the product flow direction. Due to the negative pressure applied to the turning drum, the product is in contact with it.
  • Partial shielding 14 of the inside of the drum transfers the product from the drum to the screen belt 15 in the transfer area. This transports the product through the opening 16 into the chambers 17 of the insulated housing 18. In order not to create any confusion, the opening 16 must be correspondingly large.
  • Fresh air is drawn in laterally within the chambers 17 through the adjustable flaps 19 and blown onto the product by the fan 20 via the heat exchanger 21. A partial flow from each chamber is discharged via line 22 from the common exhaust fan 23.
  • the slide made with an S-shaped profile, over which the crumble cake slides from the crimping nozzle onto the sieve belt, lies straight across the conveying direction and has an inclination angle of 60 ° and a radius in the transition area of 125 mm.
  • the crimp vapor is circulated at 110 ° C and 1.5 m / sec from top to bottom, based on the product.
  • the cooking shrinkage is reduced from 25 to 2%.
  • the crumble cake is transported through the intermediate zone of 0.5 m into the 7 drying zones, each 2.5 m, and air at 140 ° C and 1.5 m / sec is applied to it, in two subsequent cooling zones, each 2.5 m cooled to about 60 ° C and withdrawn from a withdrawal zone of 2 m and fed to a packaging unit.
  • the material is completely shrunk and has a moisture content of 2 /.
  • a 10 ktex polyacrylonitrile sliver is made at a speed of 1200 m / min, a temperature of 100 ° C and a moisture content based on solids of 50% to a round crimping nozzle, which is operated with 120 kg / h steam.
  • the crimp cake is transferred to a traversing device inclined at 33 ° to the horizontal, from which it is paneled onto an oscillating conveyor of 750 mm working width via an arched chute with an S-shaped profile with a 55 ° inclination and a radius of 100 mm in the transition area.
  • the conveying speed is 2 m / min and the occupancy is 8 kg / m 2 .
  • the ruffled steam is circulated at 105 ° C at 1.2 m / sec from bottom to top.
  • the intermediate zone of 0.5 m
  • the two cooling zones are followed by the take-off zone, from which the strip is fed to a cutting edge.
  • the product has shrunk and has a moisture content of 1.5%.
