Definitions

  • the invention relates to a high-performance drafting system and method, called drafting system and method briefly, as it is preferably used for the processing of short staple fibers at the highest distortion and operating speeds.
  • Fields of application are: centrifuge, air, friction and spin knitting processes, which work without exceptions with working speeds far above the ring spinning.
  • the current state of the art uses multi-roll drafting machines which operate with aprons in the main draft zones.
  • Various built-in components such as compressors and mechanical rotary tubes are used in the draft zones.
  • Next suctioned straps have become known that serve the compaction.
  • the bottom rollers used are provided with straight or oblique corrugations, which ensure good clamping of the material in the roller pairs.
  • the object of the invention has been found to propose an insertion or drafting arrangements, with a faultless distortion work is done and the effects of 2nd order are controlled.
  • the purpose of the invention is to provide a drafting / drafting system for high performance spinning processes.
  • a drafting system for strip processing and without compaction is a roller drafting system with three drafting zones which, in the direction of material travel, are to be referred to as the drafting zone, the stressing zone and the main drafting zone.
  • the drafting zone the stressing zone
  • the main drafting zone Above and below the corresponding upper and lower rollers are air ducts, which lead a continuous and preferably directed against the material direction of air flow, which is in relation to the environment under low vacuum.
  • the spaces between the roller pairs have covers between which the material runs.
  • a trocar feeds the material to the input rollers.
  • the material flow is adequately shielded from the air ducts.
  • At least one of the delivery rollers is assigned a blower nozzle which blows air at high speed at an overpressure of 150 m WS below the vertex to the corresponding upper / lower roller.
  • a usual technologically induced suction of the output sub-roller may be assigned.
  • the first three top rollers seen in the material direction, are located on a common pressure arm.
  • the output top roller is stored separately and iridescent.
  • turbulence brake in the main drafting zone on each of the upper / lower rollers. It is a knife-like structure that touches the roller or is set to the narrowest gap.
  • the drafting system at the input upper roller of the main drafting zone is modified in a special embodiment.
  • the input top roller carries a strap cage which one wraparound, air-permeable ribbon known type carries.
  • the ribbon is rolling and is covered by an internal suction box.
  • the suction box has an opening which tapers in the material direction from about 10 mm to about 5 mm.
  • the modification is not for compacting but for improving the shrinkage of short fibers into the exit rollers by increasing the retention force.
  • the ribbon has a gap overlying a cover over it which just touches the material flow without squeezing it.
  • FIG. 2a cross section A-A with respect to FIG. 1
  • FIG. 2b shows cross-section A-A for an embodiment of spinning-knitting machines
  • Fig. 7 main draft zone / cross section for processing of extremely short staple material
  • Fig. 8 top view of the retention zone
  • Fig. 1 shows the cross section of a drafting system according to the invention for strip processing. It has four bottom rollers 1 and four top rollers 2. The gap of the roller pairs is covered by covers 3.
  • the insert has three stretching zones, which are referred to as Vorverzugszone W, Anspannverzugszone VA and main drafting zone VH.
  • Vorverzugszone W slightly below the vertex of the rollers, which are subjected to a slight overpressure.
  • About 150 mm of WS proved to be sufficient.
  • the desired spin organ follows. It is for example a spinneret 5 indicated.
  • Anspannverzugsfeld VA is an open compressor 7, which has at its narrowest point a jaw width of about 10 mm - see Fig. 3rd
  • VH In the main drafting field VH is another open compressor 7.1 whose mouth is not narrower than 5 mm.
  • the output top roller 2.1 is stored separately and iridescent.
  • the material flow is passed through a trocar 8.
  • Fig. 2a the channels 9 are shown in cross section.
  • On the pressure arm 10 are located above and possibly laterally shields 10.1 and inside lateral shields 10.2, which shield the bearing elements of the pressure arm 10 streamlined.
  • the lower rollers 1 are shielded in the same way by shields 10.1.1 and 10.2.1.
  • Fig. 2b shows the design of the channels for use in spinning knitting machines.
  • two pressure arms 10 are brought together with a minimum distance of 10.1. It forms at the top and bottom ever a double channel.
  • Fig. 3 shows the design of the open compressor.
  • a turbulence brake 11 is provided on each delivery roller 1.1 and 1.2, which is arranged 11.1 or 11.2 with the smallest possible gap.
  • the turbulence brakes 11 prevent a collapse of the entrained by the output rollers 1.1 / 1.2 air flow, which disturbs the material run.
  • the feed rollers 1.1 / 2.1 can rotate with up to 7000 rpm!
  • FIG. 6 an inventive drafting with compacting device is shown in longitudinal section. There is an additional compaction zone VK, in which there is a spinneret 1.2 followed by a spin tube 12.1.
  • the spinneret 12 sucks in the fibers emerging from the exit rollers 1.1 / 1.2 and forms a temporary ring yarn which extends to the end of the spinning tube 12.1. Since the overall system is a false twist device arrive in the exit rollers 1.1.1 / 1.2.1 only parallel lying fibers because the rotations between the end of the spinning tube 12.1 and the output rollers 1.1.1 / 1.2.1 are completely degraded. - The material flow is however perfectly compacted. This is followed by a spinning system of known type.
  • Fig. 6 the particular feature of the spinneret 12 is shown.
  • the inlet funnel 12.2 is formed flat and extends into the exit gap, which is formed by the output rollers 1.1.1 / 1.2.1.
  • the ratio of width B to the diameter ( ⁇ 2 mm) of the spinneret D is 5: 1 ie the full width of the exiting material flow, which is between 5 and 10 mm is sucked. All leaking fibers are incorporated into the temporary yarn.
  • This nozzle design is also used in connection with the drafting system without compaction zone, when this is used for the purpose of spin knitting.
  • the input upper roller 2.1-1 of the main drafting zone VH carries a Riemchenkafig leads an air-permeable ribbon 2.1.1.1.
  • a suction box 2.1.1.2 which has a tapering in the material direction opening 2.1.1.3 - see Fig. 8.
  • the apron 2.1.1.1 is roll-guided at all deflection points 2.1.1.4, which significantly reduces the friction.
  • the opening 2.1.1.3 tapers to a final width of 5 mm, which is not sufficient for a perfect compaction. - If that is the goal, then a compaction zone VK should be arranged as described above.
  • VV / VA / VH / VK move are in the usual orders of magnitude.
  • VK can be set to NULL or quasi ZERO.
  • the loads of the top rollers 2 move in the usual orders of magnitude.
  • the top rollers 2.1 and 2.1.1 can be loaded with a much lower load than the ring spinning usual, which extends the service life. - This is especially true if the spinning tension of the subsequent spinning system does not exceed 0.2 N (air spinning / spinning knitting).
  • the drafting system variants according to the invention separate the flow of material from the air streams that serve the detour. It created by the streamlined channels 9 from the outset no "arrivals” and “batzen". Unusually high operating speeds are clearly dominated, since turbulence in the main draw zone VH or VK can not get out of hand.
  • the particularly abrasive top rollers 2.1 / 1.2.1 are stored separately and iridescent. They can also be made much larger in diameter, which extends the service life.
