Definitions

  • the invention relates to a device for treating fiber cables with a liquid, the device having a washing tube and an injector, and to a method for treating fiber cables using such a device.
  • the fibers can be cut and suspended and passed as a staple fiber fleece on sieve belts through various bath sprinkling zones.
  • a gentler and more efficient variant of the after-treatment leads the continuous fiber cable through a closed pipe system, which is flushed through by an after-treatment liquid.
  • a jet pressure of the injectors of up to 3.0 bar is required.
  • this “hard jet” causes fiber tears.
  • Fiber tears in this area have a negative impact on further processing, but also on product quality.
  • One example is the content of long fibers in the production of staple fibers: fiber tears mean that the fibers can no longer be cut reliably, so that undesirable long fibers are found in staple fibers that are to be cut to a certain length.
  • the invention has set itself the task of overcoming these disadvantages and improving the device of the type mentioned in such a way that an endless fiber cable can be introduced into a washing pipe and washed through without causing fiber breaks or fiber tears.
  • the injector is designed as a double injector consisting of an upper and a lower injector unit, each with a hollow nozzle needle and a nozzle assembly.
  • the inner diameter of the nozzle needle and the nozzle assembly in the upper and in the lower injector unit are approximately the same and if the inner diameter of the lower injector unit is larger than the inner diameter of the upper injector unit. As a result, there is enough space in the lower injector unit that the fiber cable is surrounded by a sufficiently thick layer of liquid and is thereby protected.
  • the jet pressure of the upper and the jet pressure of the lower injector unit are preferably independently adjustable.
  • annular chamber is provided above each nozzle opening, into which the inflows of the moving medium open.
  • the jet pressure difference between the upper and lower injector unit is 0.5-2 bar, preferably approximately 1.0 bar, and if the ratio of the amounts of liquid which are supplied by the upper and lower injector unit is between 1: 1 and 1: 5 and preferably 1: 3. It is possible to treat fiber cables consisting of 6,000 - 5,000,000 single filaments.
  • FIG. 1 shows a double injector as can be used according to the invention in a device for treating fiber cables;
  • Fig. 2 shows a modification thereof; and
  • FIG. 3 shows the pressure conditions in the injector according to FIG. 1.
  • the double injector consists of a fixed middle part 1, the upper part of which forms the nozzle assembly of the upper injector unit 2 and the lower part of which represents the nozzle needle of the lower injector unit 3.
  • a tubular upper part 16 which can be moved by screws is provided as the nozzle needle for the upper injector unit 2.
  • the nozzle opening 4 can be adjusted by moving this upper part 16 up and down.
  • this upper part has a funnel-shaped extension 18 for receiving and guiding a fiber cable 6.
  • the lower injector unit 3 consists of a likewise movable, tubular lower part 17, the uppermost part of which forms the nozzle assembly.
  • the nozzle opening 5 of the lower injector unit is formed. Open laterally above the nozzle openings 4 and 5 the inflows 7 and 8 of the moving medium into annular chambers 9 and 10 before the medium comes into contact with the fiber cable under pressure through the nozzle openings 4 and 5, respectively.
  • the shape of the annular chamber 9 and 10 is designed so that there is no lateral overpressure.
  • the fiber bundle 6 can be drawn into the double injector very gently with a jet pressure reduced compared to the lower injector unit 3 and part of the total washing liquid.
  • the fiber bundle 6 is embedded in washing liquid and fed to the lower injector unit 3.
  • the lower injector unit 3 can be operated with a jet pressure which is up to 2 bar higher than that of the upper injector unit 2; the remaining amount of washing liquid is added.
  • the high jet pressure no longer reaches the individual fibers, because these are surrounded by the liquid supplied in the upper injector unit 2 and thus protected.
  • the desired, safe insertion of the fiber bundle into the individual washing zones can thus take place in a gentle manner.
  • the funnel-shaped part which introduces the fiber cable into the double injector can additionally be equipped with pull-in aids.
  • FIG. 11 represents the inflow of the rinsing liquid which, via the annular chamber 12, passes the overflow channels 13 into the nozzle annular chamber 14 and detects the fiber cable immediately after it emerges from the annular gap 15 and continues to wash it.
  • the nozzle cross-sections can be changed by moving the nozzle needles in the nozzle assembly and thus the flow conditions can be optimized so that fiber breaks are excluded.
  • An endless fiber cable made of HWM fibers * consisting of 530,000 filaments with a single titer of 1.7 dtex is drawn off at a speed of 25 m / min and inserted into a pipe washing system using a double injector.
  • the jet pressure in the upper injector is 0.5 bar. 1000 l of acid water are pumped through per hour.
  • the jet pressure in the lower injector is 1.5 bar.
  • FIG 3 illustrates the flow conditions in the individual sections of the double injector, which occur in this example. For this purpose it is shown next to it.
  • the fiber speed v is shown in broken lines
  • the quantity of bath Q is shown in dotted lines
  • the liquid velocity w is shown in broken lines.
  • a squeeze roller can be provided, which causes bath separation.
  • the cable can then be introduced into the next post-treatment bath using a second double injector.
  • An endless fiber cable made of viscose fibers that have incorporated graphite consists of 312,000 filaments with a single titer of 5.5 dtex. It is drawn off at a speed of 25 m / min and introduced into a pipe washing system using a double injector.
  • the jet pressure in the upper injector is 0.5 bar. 2000 l of acid water are pumped through per hour.
  • the jet pressure in the lower injector is 2.0 bar.
  • the amount of liquid is 5000 l / h.
  • An endless fiber cable made of viscose-cotton type (ZS fiber production) consisting of 53,000 filaments with a single titer of 1.3 dtex is taken off at a speed of 60 m / min pulled and introduced into a pipe washing system by means of a double injector.
  • the jet pressure in the upper injector is 0.7 bar. 500 l of acid water are pumped through per hour.
  • the jet pressure in the lower injector is 1.5 bar.
  • the amount of liquid is 1200 l / h.
  • An endless fiber cable made of cellulose fibers consisting of 10,000 filaments with a single titer of 1.7 dtex is drawn off at a speed of 60 m / min and introduced into a pipe washing system using a double injector.
  • the jet pressure in the upper injector is 0.5 bar. 500 l of wash water / hour are pumped through.
  • the jet pressure in the lower injector is 1.0 bar.
  • the amount of liquid is 5000 l / h.
