Definitions

  • the invention relates to a method for open-end rotor spinning, in which the fibers to be spun over a Fiber guide channel conveyed into the rotor, the largest of which Rotor groove with inner diameter collected by the Rotor rotation under rotation in the area of a so-called Embedding zone integrated into the yarn end and as a finished yarn through a center and essentially in one plane with the Discharge nozzle arranged in the rotor groove can be pulled off.
  • JP-OS 49-54 639 A malfunction, as can be seen in JP-OS 49-54 639, due to strong impurities in the rotor, strong Fiber bundling or the failure of the vacuum supply are caused.
  • the resulting overturning of the Yarn end curvature is like this one in Japanese Disclosure Document has been described undesirable because the thread produced in this way in strength and Uniformity considerable disadvantages compared to a thread should have, in which the thread end in the direction of rotor rotation is curved.
  • To counter this tipping of the curvature Avoiding the direction of rotor rotation is described in JP-OS 49-54 639 proposed corresponding to the discharge nozzle and rotor base Arrange thread contact elements that the desired Stabilize the direction of curvature.
  • the invention is characterized by the features of claims 2 to 5 advantageously trained.
  • the method according to the invention is based on the finding that that with a direction of curvature of the thread end in Direction of rotation fibers coming from the fiber slide coming, reach the binding zone of the yarn end directly, initially in the opposite direction to the normal direction of yarn rotation Direction to be tied to the spinning yarn, after which at further withdrawal of the yarn with simultaneous rotation of the same around its own axis the direction of rotation of this fiber in the Main yarn direction changes.
  • the Fiber with its front end in the direction of rotor rotation reached the embedding zone first, at Direction of rotation of the fiber several locally concentrated Wraps arise.
  • the thread is constricted at this point with the consequence of thread unevenness and a slowed rotation propagation, which in turn leads to a Loss of strength in the thread leads.
  • the angular velocity of the separation point differs or the integration zone from the angular velocity of the rotor.
  • the binding zone hurries the rotor.
  • one Curvature of the yarn end against the direction of rotation of the rotor hurries the binding zone after the rotor.
  • the lag of the embedding zone already during the Piecing process can be set.
  • the means used to generate the rotational flow can also be used for so-called rotor flushing if the from a so-called fiber beard equalization fibers got into the rotor before the actual piecing must be removed again (see for example DE 197 09 747 A1).
  • Curvature of the yarn leg or the lag consists in the creation of a thread loop during the piecing process.
  • the thread end as usual, through the thread take-off tube into the rotor. Then a is in a radially spaced suction channel Suction flow is generated while the spinning vacuum is switched off becomes. This causes the thread end to migrate from the take-off nozzle this suction channel.
  • the conveyor length is controlled by the
  • the thread feed is controlled by the thread take-off tube. After the end of the feed, the thread end is in the suction channel clamped. Then vacuum is generated again and the rotor started. By further returning the thread a larger loop is formed between the discharge tube and Suction channel off.
  • Stopping fiber feeding before piecing is here not tied to a specific procedure. So can the fed fiber beard immediately downstream of the feed table can be redirected by suction air as long as this is necessary is. On the other hand, it is also possible to point this out Fiber flow deflection in the area of the fiber feed channel (see for example DE 31 18 382 A1). critical is only that in the piecing phase, in which the Direction of curvature of the thread forms the fiber feed is completely stopped.
  • FIG 1a the phases of the connection of a single fiber 4 during spinning with a leading binding zone, that is, the orientation of the yarn leg 3 in the direction of rotor rotation, are shown, this single fiber 4 reaching the fiber groove 2 into the rotor groove 1 at a time when its front end in the binding zone 5 of the yarn leg 3 is detected (phase 1).

  • the fiber 4 gripped with its tip is first wound around the yarn jacket in an S rotation.
  • the tip of the fiber 4 approaches the point at which other parts of the fiber 4 are currently being wound around the yarn jacket.
  • phase 4 there is a change in the direction of rotation of the fiber 4 from S to Z, whereby several concentrated loops can arise. Overall, these loops constrict the yarn and form so-called belly bandages, which can interfere in the later processing process and reduce the overall quality of the yarn.
  • phase 5 it can then still be seen that the rest of the fiber 4 is then wound in a Z-twist, that is to say in the same twist as the rest of the yarn.
  • Phase 1 hits the fiber on the binding zone and is in Phase 2 through the yarn leg 3 in the area of the binding zone 5 detected.
  • the fiber tip of the fiber 4 follows the direction of rotation ⁇ G of the yarn on its own axis and becomes complete Deduction deducted from the rotor groove 1 in the Z rotation and around the Thread core wound (phases 3 to 5) while the fiber end in S twist is wound around the fiber core.
  • the fiber is not firmly integrated in the yarn core, but lies loosely around the Yarn surface.
  • FIGS. 2a and 2b show how the Connection of a single fiber 4 within the integration zone 5 takes place on the yarn leg 3 if with a lagging Embedding zone 5, that is, with a curvature of the Yarn leg is spun against the direction of rotation of the rotor.
  • Figure 2a shows in phases 1 to 5, like a fiber 4, the with its tip, coming from the fiber slide surface 2, the Tie-in zone 5 is reached around the yarn jacket. It can be seen that the fiber 4 in the tied the same direction of rotation to the twine leg 3 becomes like all other fibers. The only difference is Slope of twist slightly from the remaining fibers. As well it is the case according to FIG. 2b if the fiber 4 is initially included reached the end of the tie-in zone 5.
  • the yarns produced in this way consequently contain no more fibers, which is a normal direction of yarn rotation have different turns. But especially there are no constrictions due to changes in the direction of rotation the yarn quality and thus the possible uses of the affect spun yarn.
