Definitions

  • the invention relates to a method for producing a yarn, in which a fiber sliver delivered by a drafting system first subjected to compression and then rotated and is wound up as well as a spinning machine, by means of which a such procedure is executable.
  • Compaction devices in the form of with a perforation track provided, rotating, cylindrical rollers (DE 44 26 249 A1) or of circumferential, perforated Flexible straps (EP 0 635 590 A2) are known.
  • the compression of a fiber sliver delivered by a drafting system offers the advantage that the fiber sliver is summarized closely can be fed to the twist zone in which it becomes a yarn is solidified. Jumps into this tightly summarized fiber sliver the rotation given to it by the rotation device to close to the clamping line, i.e. the spinning triangle is very small. This has the consequence that the loss of splitting edge fibers is minimal and that the yarn produced has little protruding fibers has, i.e. has little hairiness.
  • the invention therefore provides that delivered by a drafting system First subject the fiber sliver to compression before being solidified and coiled by giving rotation becomes.
  • the spinning machine according to the invention for performing this method accordingly has drafting systems with compression devices as well as pot spinning devices.
  • the one at the exit of a Drafting device arranged compression devices can be used as rotating, rigid, hollow and internally under suction suction rollers with a perforation track on their circumference or as circumferential belts, preferably in the form of straps be trained.
  • the perforation track under suction is in the direction of the movement of the fiber sliver Row of small suction openings to which the fibers of the fiber sliver are attached be sucked in.
  • the pot spinning devices can be of any known type be.
  • the device according to the invention also with devices for manufacturing by coregarn and / or false twine.
  • the core thread In a core yarn, the core thread should be as complete as possible the sheath fibers that determine the outer appearance of the yarn be embedded. Done in normal core yarn spinning this is because the core thread of the last, as a rule, that is, in the main warping area, the fiber sliver has spread widely apart is fed while laying the sheath fibers around the Core thread by rotating the fiber structure between the pair of output rollers and the organ giving the rotation, in all So usually a ring spinning spindle takes place. This embedding is done often incomplete in some places along the yarn, which represents a loss in quality of the core yarn produced.
  • a particularly effective embedding of the core thread is then achieved if this according to the invention before the compression zone fiber sliver still lying there is fed as centrally as possible becomes. This is particularly the case if the core thread is the Output roller pair of the drafting system fed on its inlet side becomes.
  • the core thread can also be direct be fed to the compression zone.
  • the core thread Drafting system fed from that side - from above or from below on which the strappy is arranged and around the Deflection edge on the inlet side of the apron.
  • the apron is in the area of its inlet side assigned a guide roller around which the core thread is guided. If the compaction device has a suction roller, can the core thread can also be fed to the circumference of this suction roller.
  • each fiber sliver is one Core thread runs in or several core threads run in and out a core yarn is formed by twisting. It is however also possible, in particular two with at least one Core threads doped fiber lunches converge before giving rotation and then only by giving rotation to produce a so-called false thread from two core yarns.
  • a false thread is a textile thread, at to which two untwisted fibers are given rotation together.
  • the two fibers are wrapped around each other and given the fiber structure thus formed rotation.
  • Real thread this false twist differs in that the two Components do not have their own rotation, but only by the looping around by turning them together in the end product are kept similarly separate from one another real thread is the case.
