Definitions

  • the invention relates to a method for continuous Production of a twine with a low tendency to curl.
  • Staple fiber yarns are finally made of long individual fibers manufactured, aligned and bundled in parallel become.
  • the fibers are mostly natural fibers, e.g. Wool and cotton. But you can also use synthetic fibers getting produced.
  • the result is a yarn with greatly improved dynamometric properties.
  • the fiber bundle - but also the individual in the bundle located fiber - takes the imprinted rotation (the torque) only against the resistance of the inner Forces of the individual fibers. Only after a certain time has elapsed Time span and at the same time the Thread tension leads to a so-called relaxation in the twisted fiber strand, i.e. there is a state of equilibrium the internal fiber forces, i.e. by the shape imposed on the spinning process is "frozen".
  • the spun threads or spun yarns have a shape memory, which during the twisting process de Counteracts the twist of the thread. It can therefore in the twine to an imbalance between those caused by the Forced twisting and the de twisting Spinning strands and the individual fibers come forces
  • the result is a lively, strong to curl tending thread, the intensity of curling tendency in a direct link to the extent of the Spinning process granted rotation of the spun threads on the one hand and the degree of twist on the other hand.
  • This behavior of the thread can be the same as for the filament only by a deposition process or by artificial Fixing counteracted as part of a damp / heat treatment become.
  • the combined spinning and twisting process only describes in a general way, without one
  • the DE describes specifying a constructive solution 44 30 917 C1 a constructive solution for the implementation an integrated spinning-twisting process.
  • there are dissolved individual fibers at least two in one shared rotor mounted OE spinning units, which are arranged within a double wire spindle are such that the means of the OE spinning units produced spun threads immediately after their Generation according to the double wire twisting process to be twisted into a thread.
  • FR 15 52 320 follows at least two stationary in a common machine frame mounted OE spinning rotor on a ring twisting unit, however, it is questionable whether due to the different Processing speeds of OE spinning rotors on the one hand and ring twisting units on the other this procedure is practicable at all.
  • the dissolved individual fibers two OE spinning units mounted in a common rotor fed through the rotor axis, and the are emerging from the spinning aggregates immediately afterwards subjected to a single-wire twisting process.
  • the invention has for its object a low torque To produce twine with a low tendency to curl, the can be processed directly and easily without that longer deposition times in the sense of the above statements or additional fixation procedures are required.
  • the method according to the invention with the means available on the filing date can be carried out that it is the upstream Spinning process taking into account the downstream Twisting process around an OE spinning process or Air spinning process.
  • the solution to the desired goal is for the spinning process and the twisting process an uninterrupted process with almost constant thread tension (Thread tension) and a very short time phase or distance between the completed spinning process and the twine binding zone and thus also the termination the twisting phase. So that after the Introduction of the spin twist to produce the single spun yarns striving the fiber bundle back into one parallel position or the formation of a shape memory to the spin spin state only a minimal amount of time made available. Because of the constant the thread tension or thread tension becomes a "freeze" the twisted fiber bundles and individual fibers as well counteracted.
  • Thread tension thread tension
  • the thread tension parameters specified in claims 1 and 2 depend on the staple fiber material to be processed, the embodiment of the device used and the respective process parameters.
  • the tensile force values can preferably be obtained from delivery plants between the spinning zone and the twisting zone.
  • the single spun yarns have the thread tension very little resistance to the following Twisting, and a spinning / twisting twist is formed, whose internal restoring moments are minimal. Since that Restoring moment in the package based on those described above Connections with it is minimized Equilibrium by relaxing the threads on the Wind up after a very short time. That way the memory effect in the elastic thread medium and in elastic spinning medium almost completely avoided and it will thus also not transferred to the twisted state, whereby the curling tendency is largely switched off.
  • you put the time interval between the End of the spinning phase and the end of the twisting phase to a value of ⁇ 0.5 second, and in particular ⁇ 0.1 Second, firm.
  • spinning-thread delivery speeds are preferably selected: nm tex Delivery speed range m / min 2.20 50 x 2 100-200 50/2 20 x 2 60-170 70/2 14 x 2 40-140
  • the device shown in Figure 1 comprises a in a machine bed 1 mounted conventional ring twist spindle 2, the two each shown as black boxes Spinning units 3.3 are connected upstream. It can are each a common air spinning unit, in which, according to DE 40 04 049 A1, one to a desired one Yarn count stretched sliver fed to an air nozzle , which is a particularly tubular thread channel has, in which at least one blowing nozzle opens tangentially, in order to effect the spinning process in the thread channel Vortex flow with a given direction of rotation to create.
  • the ring twisting spindle 2 comprises for the rotary drive a twisted bobbin 4 by means of a tangential drive belt 5 driven spindle whorls 6, as well as an up and down movable ring 7 with assigned ring traveler 8.
  • the route "a” gives the distance and, taking into account derived from the thread delivery speed, the time factor between that represented by the black boxes 3 .Spinning zone and that of the ring traveler 8 defined twisting zone. Between the spin zone and A common thread guide 9 is located in the twisting zone.
  • the device shown in Figure 2 contains one Spinning part I with at least two side by side in one Machine frame 11 mounted OE spinning rotors 12, 13, into the fiber material feed channels in the usual way 14, 15 open out.
  • This spinning part I is a double-wire twisting unit II assigned that as a double-wire twist spindle with internal Winding spool A is formed.
  • A contains as essential components such a double-wire twisting spindle using a tangential drive belt 17 drivable hollow whorls 18 that together with the thread storage disk 19 and the overflow plate 20 forms the spindle rotor.
