Definitions
- the invention relates to a device for air swirling of
- Multifilament yarns according to the preamble of claims 1 and 11. Furthermore, the invention relates to a yarn treatment process, in particular using the Garnb emaschinesvorri direction.
- Whirling nozzles for multifilament yarns are well known and are used in the spinning of plain yarns (such as FDY, POY, IDY), glass fibers and carpet yarns (BCF), on texturing machines and winders. They produce the thread closure required for further processing by knotting the filaments together at certain intervals. In some cases, this knotting gives the yarn a desired texture.
- plain yarns such as FDY, POY, IDY
- BCF carpet yarns
- the turbulators are available in both single-thread and multi-thread design.
- Verwirbelungsdüsen be charged with static compressed air, which flows through one or more blow holes in a yarn passage, which passes through the thread.
- the filaments are intertwined with each other and so-called Verwirbelungsknoten, hereinafter also called knots form.
- the number, intensity, uniformity and spacing of the knots depend essentially on the yarn with the yarn thickness and the number of filaments, the swirl nozzle design with the yarn channel geometries and blow hole, and process parameters such as yarn speed, yarn angle, yarn tension and swirl pressure.
- the number of nodes, intensity and uniformity of the turbulence can only be set to a limited extent here. But there are also Verwirbelungsdüsen in which the turbulence flows in pulsating.
- the turbulence air is sequentially interrupted by a rotating ring in which air ducts are located.
- the number of nodes can be defined here by the rotor speed and the number and spacing of the air ducts at the respective thread speed.
- Vortex air into a rotating pot which is provided at the outer periphery with holes flows.
- the pot is stored with 2 deep groove ball bearings and at the outer end of the pot is a pulley that drives the pot.
- swirling air flows into the housing Swirl chamber and the air pulse twists the filaments of the supplied yarn and knots are formed in a frequency which results from the yarn speed, the pot speed and the number of openings in the pot.
- the object of the invention is to provide a swirling device with pulsating
- the bearing of the rotating pot and the drive motor of the shaft, on which the rotating pot sits integrated into the housing of the swirling device.
- the motor is preferably a synchronous electric motor in which the rotor is fixedly connected to the shaft on which also the rotating pot sits, and the stator is firmly seated in the housing of the device.
- the device consists essentially of the following units: basic housing with receiving the stator, bearing outer rings and chambers for the supply of turbulence compressed air, shaft with rotor, bearing inner rings, rotary pot with holes for pulsation of the blown air and housing around the rotating pot with openings for the rotating blowing air or for Nozzle inserts with fixed blow channel.
- the thread is inserted into the Verwirbelungs- or yarn passage either through a slot in this or by means of an open-close unit, which opened for threading and to swirl is closed.
- the turbulence air flows via a supply line into the housing through a chamber which is arranged around the stator of the electric motor to the radially outer peripheral openings.
- the flowing turbulence air also serves to cool the engine.
- the rotating pot rotates with minimal sealing gap around the fixed housing and the blast air flows through pulsating through the opening in the pot.
- the openings through which the compressed air exits are re-introduced on the opposite side in the housing. Here, however, no air flows out, the air pressure is static. These holes cause the compressed air forces, which act radially on the pot and storage almost cancel, since they are mounted opposite.
- a housing is arranged, which completely surrounds the pot and only in the area of Garnverwirbelung has openings through which the pulsating blowing air can flow.
- the gap between the rotating pot and the pot housing is minimally designed so that the pot can rotate freely, but also only minimal compressed air can escape through the gap in the opening of the pot.
- openingslits are arranged radially on the circumference and in a plane with the openings of the housing and let the compressed air pulsing flow into the blow hole of the nozzle insert.
- the distance between the openings on the circumference to each other is preferably such that the turbulence air alternately flows through the openings in accordance with the intervals of the opening slots in the housing pot.
- the rotational speed of the rotor is preferably adjusted so that the second pulse acts in the middle between the nodes formed by the first pulse.
- the second pulse amplifies the nodes already formed by the first pulse.
- This embodiment has the advantage that the air consumption is reduced by almost half compared to the conventional tandem nozzles used in practice (two successive nozzle inserts), in which the blown air flows continuously, since it is always mainly a blow hole in use.
- the momentum of the respective blowhole creates the swirl node and only uses the air needed to form a node.
- the uniformity of the node spacing increases as well, and the length and number of untwisted places decreases.
- a nozzle insert In the execution of the device in tandem arrangement with two nozzle inserts can also, If the momentum of a single nozzle insert is sufficient for the desired turbulence, a nozzle insert can be set blind and thus the turbulence air and thus the energy requirement can be reduced by half again.
- the distances between the blow holes in two or more nozzle inserts are preferably selected so that the yarn length between two blow holes is 1.5 times the value of the predominantly desired node spacing.
- the yarn length between the blowholes is 50mm at the desired 30 knots / m, which corresponds to a knot spacing of 33.3mm.
- the Bohrungsab states can be set to a certain extent, but it is also possible to swirl through different nozzle inserts with different bore spacings.
- the frequency of the Verwirbelungscons can be additionally set.
- the nozzle inserts with the respective sizes in the yarn channels and blow holes are interchangeable.
- the blow hole is located in a rotating pot.
- the distance between the rotor pot and the pot housing is so narrow that between the rotating and the standing pot wall even at high speeds no contact takes place and as little blowing air can escape.
- the thread runs over the longitudinal slot at a speed. From the rotating bore, the blast air flows onto the running thread in the yarn channel and generates a swirling knot in the area of the longitudinal slot.
- the frequency at which the swirling pulse is generated depends on the rotational speed of the rotating pot and the number of holes and the distances of the holes which are arranged radially on the circumference.
- the speed of the rotor preferably corresponds to the yarn speed.
- the distances, number and diameter of the blow holes in the rotor pot are determined according to the yarn denier and Verwirbelungser Victoria Industries and the rotor can be changed as required.
- the rotor bores with a certain number uniformly, but also to achieve different effects can be arranged unevenly at different distances.
- the diameters or even the shape of the rotor bores can be cylindrical, elliptical as in conventional turbulence nozzles or y-shaped.
- Both of the above systems can also for multi-filament textile machines, in which the threads are arranged parallel to each other, are executed and then have several of the above-mentioned openings in the axial direction parallel to each other.
- the turbulence unit is sealed to the outside and only in the
- Turbulation zone can escape blowing air.
- the rotating pot has a minimum sealing gap to the outside and inwards. Due to the special arrangement and design of the air ducts, the forces generated by the compressed air and acting on the storage and the rotating pot, almost cancel. This allows the storage and Rotortopfwandung be carried out minimally and there are very compact dimensions.
- the invention is a Garn adaptationsvorraum for swirling
- Multifilament yarns by means of pulsating air flow, which is produced by a rotating pot ring with openings, wherein the drive motor and the storage of the pot ring are located inside the housing with its air supply channels.
- the drive of the rotor pot is an electric drive, in which the rotor of the electric motor is mounted on the shaft and the stator is seated in the housing.
- recesses are located in the housing in the region of the electric motor for engine cooling by means of circulating turbulence air.
- additional air outlet holes can be located in the housing, which almost cancel the radial forces of the compressed air to the storage.
- the rotor pot is of a

- the bearing 5 has its seat in the housing 1 on the outer diameter. Power is supplied by a cable 8, which is led to the outside. The sometimes considerable axial forces, which are present by the air pressure inside the system, are almost canceled by the closed nature of the system, since the opposing surfaces are equally pressurized.
- Fig. 2 shows the tandem arrangement in cross-section through the axis of
- the distance BA of the blow holes is preferably such that the yarn length between the two blow holes corresponds to a factor of 1.5 of the selected distance between two Verwirbelungsknoten. This is preferably between 30 and 70 mm.
- the distance of the rotor openings is chosen so that preferably only one blow hole is always supplied with compressed air.
