Definitions

  • the invention relates to a method and device for producing elastic core yarn according to the preamble of the independent claims.
  • a continuous thread is spun around with staple fibers.
  • properties of a certain continuous thread can be transferred to a finished yarn and combined with the properties of the staple fibers used.
  • the continuous thread serves as the core of the finished yarn.
  • a sheath of staple fibers is then created around this core in the spinning process.
  • an elastic continuous thread for example elastane, is used as the core, which is spun with cotton fibers.
  • a fiber sliver or a fiber structure is fed to a drafting system of a ring spinning machine.
  • the drafting system which consists of several pairs of rollers
  • the fiber structure is drawn by the different speeds of the pairs of rollers.
  • This warped fiber structure leaves the drafting system through a pair of output rollers.
  • an elastic continuous thread is fed to the fiber structure.
  • the continuous thread is unwound from a bobbin and transported to the fiber structure via a pair of delivery rollers.
  • the peripheral speed of the pair of delivery rollers is matched to the peripheral speed of the pair of output rollers in such a way that the continuous thread is stretched between the pair of delivery rollers and the pair of output rollers.
  • the fiber structure with the stretched continuous thread is transformed into an elastic yarn.
  • US3243950 discloses a method for making an elastic core yarn.
  • the automatic device for changing the bobbin cuts the yarn by pulling the bobbin off the spindle and pulling the yarn over a knife edge.
  • the yarn is drawn in length and is not reliably separated by the knife. This regularly leads to malfunctions in the automatic operation of the ring spinning machine, whereby it should be taken into account that a package change takes place at up to 2,000 spinning positions at the same time.
  • the invention is therefore based on the object of providing a method and a device for this purpose, which enable a trouble-free separation of the spun elastic yarn when changing bobbins.
  • the peripheral speed of the pair of delivery rollers determines the speed at which the elastic filament is unwound from the spool.
  • the peripheral speed of the pair of output rollers of the drafting device determines the speed at which the fiber structure is passed on to the spinning device together with the elastic continuous thread.
  • the ratio between these two speeds is matched to the material of the continuous thread used during operation.
  • the peripheral speed is of the pair of outlet rollers is higher than the peripheral speed of the pair of delivery rollers and thus the ratio mentioned is significantly greater than 1.
  • the size of the ratio determines the elongation of the continuous thread with which it leaves the pair of outlet rollers.
  • the continuous thread is passed on to the spinning device with less elongation.
  • the finished core yarn is also less elastic, since the fibers spun around the continuous yarn themselves do not allow any elongation.
  • the core yarn can only be stretched until the state is reached again in which the fiber structure with the continuous thread has passed through the spinning device. This results in better separating behavior when the core yarn is drawn off using a knife blade during automatic bobbin change.
  • the circumferential speed ratio between the pair of output rollers and the pair of delivery rollers is reduced to below 3, preferably to between 1 to 2.5, more preferably to between 1 to 1.5, during spinning. It is particularly advantageous if the circumferential speed ratio between the pair of output rollers and the pair of delivery rollers is reduced to one during spinning.
  • the spinning device produces a core yarn which, despite the use of an elastic continuous thread as the core, corresponds in its properties to a yarn which would be produced without an elastic continuous thread.
  • the same technical equipment can be used for the separation of the spun thread during an automatic bobbin change as with a staple fiber yarn which was produced without feeding an elastic core. Since the staple fibers transformed into a yarn have a very limited elasticity, the yarn breaks even with the slightest stretch. An elastic core has no influence on this behavior if it is not wound in a stretched state.
  • a device for producing an elastic core yarn with a drafting device for drawing a fiber structure, the drafting device having a pair of output rollers and a pair of delivery rollers for feeding an elastic one Endless thread is provided to the output roller pair.
  • a ring spinning device is provided for integrating the elastic continuous thread into the fiber structure, with a rotational speed ratio between the pair of output rollers and the pair of delivery rollers being reduced during spinning.
  • the circumferential speed ratio between the pair of output rollers and the pair of delivery rollers is reduced to below 3, preferably to between 1 to 2.5, more preferably to between 1 to 1.5, during spinning. It is particularly advantageous if the circumferential speed ratio between the output roller pair and the delivery roller pair is reduced to one during spinning.
  • the two peripheral speeds are advantageously provided with an electronic or mechanical coupling.
  • a control is provided which makes it possible to adapt the circumferential speed of the delivery roller pair to a circumferential speed of the output roller pair that changes during spinning.
  • the drives of the delivery roller pair and the output roller pair are mechanically connected and a switchover can take place in this connection during spinning in order to reduce the circumferential speed ratio.
  • a spinning station of a ring spinning machine comprises a drafting device 1 with an output roller pair 3.
  • the drafting device 1 is exemplarily with an input roller pair 13 and a middle roller pair 14 each wrapped with a strap 15 Drafting system 1 warped.
  • the Fiber structure 2 is supplied with an elastic continuous thread 8. The supply takes place via a delivery roller pair 9, which unwinds the continuous thread 8 from a supply spool 10.
  • the fiber structure 2 and the continuous thread 8 are guided to a traveler 5 via a thread guide 4.
  • the rotor 4 rotates on a ring 6 around a rotating bobbin 7.
  • the fiber structure 2 together with the continuous thread 8 is converted into a finished core yarn and is simultaneously wound onto the bobbin 7.
  • the ring 6 is attached to a ring rail 11, which moves back and forth or up and down along the bobbin axis 12, which results in an even winding of the core yarn on the bobbin 7.
  • the circumferential speed of the pair of delivery rollers 9 is related to the circumferential speed of the pair of output rollers 3, which is determined by the material of the continuous thread 8 used during operation.
  • the circumferential speed ratio between the pair of output rollers 3 and the pair of delivery rollers 9 is reduced to below 3, preferably to between 1 to 2.5, more preferably to between 1 to 1.5, during spinning. It is particularly advantageous if the circumferential speed ratio between the pair of output rollers and the pair of delivery rollers is reduced to one during spinning.
  • the spinning device produces a core yarn which, despite the use of an elastic continuous thread as the core, corresponds in its properties to a yarn which would be produced without an elastic continuous thread.
  • the same technical device can be used for the separation of the spun thread during an automatic bobbin change as in the case of a staple fiber yarn which was produced without feeding an elastic core. Since the staple fibers transformed into a yarn have a very limited elasticity, the yarn breaks even with the slightest stretch. An elastic core has no influence on this behavior if it is not wound in a stretched state.
  • the two peripheral speeds are provided with a coupling 16. This can be done electronically or mechanically.
  • a control is provided which makes it possible to adjust the circumferential speed of the delivery roller pair to a circumferential speed which changes during spinning of the pair of output rollers.
  • the drives of the delivery roller pair and the output roller pair are connected and a changeover can take place in this connection during spinning in order to reduce the circumferential speed ratio.
