Definitions

  • the invention relates to a spinning station of an air jet spinning machine for spinning a fiber structure into a yarn.
  • the spinning station has a delivery roller pair and a spinneret, wherein the spinneret has a Garn Strukturselement and a fiber guide element.

  • Air jet spinning machines with appropriately equipped spinning stations serve to produce a yarn from an elongated fiber structure.
  • the outer fibers of the fiber composite are wound around the inner core fibers in the area of an inlet mouth of the yarn formation element by means of a vortex air flow generated by air nozzles within the spinneret, and finally form the binder fibers which determine the desired strength of the yarn.
  • This creates a yarn with a rotation, which finally discharged via a Garn Adjustskanal from the spinneret and z. B. can be wound on a spool.

  • man-made fibers for example polyesters, or blends of natural and man-made fibers
  • deposits are formed on the surface of the yarn-forming element.
  • the production of man-made fibers involves a so-called preparation of the continuous fibers during the manufacturing process, while a spin finish, usually oils with various additives, is applied to the continuous fibers, which enables a treatment such as stretching the continuous fibers at high speeds. Some of these preparation agents remain adhering to the chemical fibers in the further treatment and lead to impurities in the air jet spinning machine.
  • the fibers supplied to the air jet spinning machine in the form of a fiber structure are usually supplied to the spinneret by a delivery roller pair.
  • the delivery roller pair may correspond to an output roller pair of a drafting system. Used drafting systems serve to refine the submitted fiber structure before entering the spinneret.
  • a fiber guide element is arranged, via which the fiber structure is guided into the spinneret to the yarn-forming element.
  • Garn Guesss institute spindles are used with an inner yarn guide channel majority.
  • compressed air is introduced through the housing wall of the spinneret such that there is a rotating fluidized air flow.

  • the dosage and addition of the additive is separately provided for each spinning station in the disclosed embodiment.
  • the additive must be fed into an environment with an increased ambient pressure, which makes correspondingly high demands on the metering device.

  • a means for supplying an additive to the fiber structure is provided between the delivery roller pair and the end of the fiber guide element.
  • Air jet spinning machines usually have several spinning stations. At each spinning station, a yarn is produced independently of the other spinning stations from a submitted fiber structure. The independence of the individual spinning stations from each other can go so far that different yarns or yarns made of different materials can be produced on adjacent spinning stations.
  • the presented fiber structure consists of an accumulation of individual fibers, which are aligned in the longitudinal direction of the fiber structure.
  • the fibers of a fiber structure can consist of different materials. Frequently used are manmade fibers made of various types of synthetic materials and cotton fibers and mixtures thereof.

  • fiber guide elements are used, which guide the fiber structure on a flat or curved sliding surface.
  • the introduced into the spinneret compressed air occurs for a part together with the yarn from the spinneret and is discharged to another part via an exhaust pipe from the spinneret. Due to the air flow in the spinneret and the resulting flow conditions creates a suction in the fiber guide element. Due to the flow conditions in the spinneret, ambient air is drawn into the spinneret via the fiber guide element. As a result, there is a negative pressure at the point of entry of the fiber structure into the fiber guiding element. The suction effect on the environment is further enhanced by the fiber structure moving into the fiber guiding element. This circumstance makes use of the invention, so that between the delivery roller pair and the end of the fiber guide element means for supplying an additive to the fiber structure is provided.
