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 by means of a ring spinning device is rotated and wound as well a spinning machine by means of which such a method is carried out can be.
  • 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 method according to the invention is accordingly based on stretched unconsolidated fiber sliver, compresses this fiber sliver and turns these compressed fiber lunches without a thread balloon or thread balloon reduced by means of spindle attachments on spinning spindles of ring spinning devices before using these ring spinning devices be wound up.
  • a spinning machine for performing this method has a drafting system, at the exit of which a below Suction-suction device that conveys and compresses the sliver is arranged, which is a perforation track, i.e. one in Direction of the movement of the fiber sliver running row smaller Has suction openings to which the fibers of the fiber sliver are sucked become.
  • the compression device is a ring spinning device downstream, whose spinning spindle with spindle attachments for thread balloonless or thread balloon reduced turning and winding of the yarn.
  • the compaction devices can be rotating, rigid, hollow suction rolls, as suction rotors or as rotating, flexible Suction straps should be formed inside with suction stand.
  • the spindle attachments can be used as spinning fingers or as Spinning crowns are formed.
  • 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 outer fibers that determine the external appearance are embedded become. In normal core yarn spinning, this is done by that the core thread of the last, usually in the Main area of warp fed wide spread fiber sliver while the sheath fibers are wrapped around the core thread by rotating the fiber structure between the pair of output rollers and the organ giving the rotation, as a rule that is, a ring spinning spindle. This embedding takes place on some places along the yarn often incomplete what represents a loss in quality of the core yarn produced.
  • the joint compression of the fiber sliver and the embedded in it Core thread in the sheath fibers in addition to screwing by compacting does a more effective, less Gaps and more uniform over the length of the yarn Covering the core thread with the sheath fibers.
  • each fiber sliver is one Core thread comes in or several core threads come in and a core yarn is formed from it by twisting. It is however also possible, in particular two with at least one Core yarn doped fiber lunches run together 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.
  • a false thread appears the more similar to a real thread, ever the two components remain more clearly recognizable in the false twine.
  • the fibers that make up each of the consists of two fiber lunches combined into a compact fiber structure, which when merging is far less condensed with the respective other fiber structure.
  • the the two fiber associations therefore remain more clearly separated and the false thread appears more like a real thread.
  • 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.
