Definitions

  • the invention relates to a device for spinning a sliver according to the preamble of patent claim 1.
  • a device for nozzle spinning is known from DE 3541219 A1.
  • This device consists of an injector part and an adjoining swirl part.
  • the injector and swirl section are immediately downstream of a drafting system for drawing a sliver.
  • a good yarn is produced in such a device, but the winding of the yarn core with edge fibers is not entirely satisfactory.
  • EP-A-418 694 shows a nozzle construction which, by means of an insert, creates a "shoulder" in the thread passage, with air inlet bores opening into the passage after the shoulder (viewed in the direction of passage). This construction also represents a step forward, but it is not the optimal solution.
  • EP-A-449 073 and EP-A-450 361 show drafting arrangements which are suitable for nozzle spinning.
  • the object of the present invention is therefore to design the elements “swirl transmitter” or “injector part” in such a way that each can optimally fulfill its subtask without interfering with another element of the system in the fulfillment of its task.
  • a nozzle construction according to EP-A-418 694 is assumed.
  • the fiber sliver is drawn and fanned out in the drafting system and in this state reaches the injector part first. Edge fibers are sucked in here and placed on the yarn core which is twisted incorrectly due to the twist effect of the twist part.
  • the passage opening for the sliver is initially narrow and then widens in a shoulder shape. Immediately after the shoulder-shaped expansion, an air inlet hole opens into the interior of the swirl part. The sliver does not lie against the inner wall of the swirl part in the area of the air inlet bore.
  • the air jet which enters the interior of the swirl part through the air inlet bore, thus hits the fiber structure, which is on the side in this area not along which the inner wall of the swirl part is guided.
  • the air jet therefore has a very good point of attack on the fibers of the fiber structure at this point.
  • the thread part of the fiber structure which moves spirally in the interior of the swirl part and which does not slide along the wall is rotated like a crank by the air flow, damage to the thread being avoided by friction on the inner wall of the swirl part. Due to the good point of attack according to the invention for the Air inlet bore incoming air, a good swirl effect is generated. This twist continues up to the drafting system, where the winding fibers are made available outside the spinning triangle. This creates a narrow spinning triangle.
  • the sliver emerges from the drafting system with a width that is at least one and a half times the inner diameter of the injector nozzle. This means that the width of the fiber sliver at the drafting system outlet is wider than the spinning triangle. This targeted production of the wrapping fibers enables the finally parallel lying core fibers to be wrapped with the edge fibers and thus good yarn strength.
  • the shorter design of the swirl part in comparison to the injector part enables on the one hand the optimization of the swirl generation and on the other hand the even application of the edge fibers to the core (winding around the core).
  • the latter task requires, first of all, the emergence of a state which enables uniform winding, and then the maintenance of flow conditions and the resulting rotary movements which cause the winding.
  • the friction on the wall of the injector part plays a positive role here.
  • twist part On the other hand, there should be as little friction as possible of the yarn on the walls of the twister because such friction impedes the twist generation.
  • the maximum possible delivery speed for a given wrong twist is also increased by a higher yarn speed.
  • the length of the twist part is to be chosen so that the spiral can form in the yarn, which (under the effect of the air flow) is the actual "twist generator".
  • the length of the injector part is preferably at least 30% and at most up to 100% greater than the length of the Swirl part.
  • the injector part is preferably between 30% and 60% longer than the swirl part. In the preferred embodiment, the injector part is 50% longer than the swirl part.
  • the length of the swirl part can be selected between 25 and 35 mm (preferably 30 mm).
  • the length of the injector part is preferably at least 40 mm.
  • the injector part has a substantially constant cylindrical inner diameter.
  • the rotation of the thread is not hindered.
  • low friction losses and damage to the thread are caused.
  • the low-friction rotation of the thread in the injector part is given in particular when the expanded inside diameter of the swirl part is equal to or smaller than the inside diameter of the injector part.
  • the distance of the air inlet bore from the shoulder-shaped enlargement should be equal to or less than the difference between the inner radii of the swirl part and thus the shoulder height. This ensures that the air jet has a particularly good point of attack on the wrapping fibers.
  • an expanded inner diameter of the swirl part between 2.2 and 2.8 mm has been found to be particularly advantageous.
  • the air jet acting on the thread acts particularly effective.
  • the fibers are immediately impacted by the air jet after the shoulder and rotated vigorously.
  • a ratio of the extended inner diameter to the length of 1 to 6 to 1 to 16 has proven to be an advantageous length of the swirl part. With a ratio of 1 to 12 to 1 to 14, yarns of the best quality and strength can be achieved.
  • the air inlet bores arranged in the injector part are advantageously arranged at an angle of 30 ° to the axis of the injector part.
  • a good wrap around the core fibers by the edge fibers is achieved if the width of the sliver emerging from the drafting device is greater than the inside diameter of the injector part.
  • a width and a half of the sliver compared to the inside diameter of the injector part has been found to be particularly advantageous. In this case, the sliver is loosely fed into the air jets and can therefore be easily twisted.
  • the distance of the air inlet bore from the shoulder-shaped extension in the swirl part is less than 0.5 mm. This allowed very good spinning results to be achieved.
  • FIG. 1 shows a device according to the invention for spinning a fiber sliver.
  • An injector part 1 and a swirl part 2 form a pneumatic swirl device.
  • This swirl device is arranged downstream of a pair of delivery rollers 3, 4 in the running direction of a sliver (not shown).
  • the delivery roller pair 3, 4 is the last roller pair of a drafting system, in which a delivered fiber sliver is drawn down to spinning strength.
  • the sliver comes out of the delivery rollers 3, 4 in a width which is larger than the inside diameter A of the injector part 1.

  • the air inlet bores 10, 11 are arranged at an angle ⁇ in the injector part 1.
  • An angle of about 30 ° between the axis of the injector part 1 and the axis of the air inlet bore has proven to be advantageous. With this angle ⁇ , particularly good guidance of the future wrapping fibers is achieved.
  • the interior 12 of the injector part 1 is cylindrical.
  • the swirl part 2 is arranged at a short distance from the injector part 1.
  • the sliver is on entry led into the swirl part 2 first into a narrow point 220.
  • the constriction 220 has a diameter C which is smaller than the diameter A of the injector part 1.
  • the diameter C is not so small that the constriction 220 acts as a twist stop on the thread or can become blocked when passing through a thick point in the yarn.
  • the narrowing 220 is followed by a shoulder-shaped widening to the diameter D.
  • An advantageous diameter D has a value between 2.2 and 2.8 mm.
  • the constriction should be short in order to keep the friction of the thread against the wall of the constriction 220 low.
  • air inlet bores 200, 210 are arranged, through which air flows into the interior 230.
  • the shoulder-shaped enlargement in a particularly advantageous manner ensures that the incoming air can very well act on the thread part located in the interior 230.
  • the good point of attack for the air also creates a good swirl effect on the thread.
  • the thread that does not slide along the wall of the interior 230 at the location of the air inlet bores 200, 210 is rotated like a crank by the air flow. This rotation is mostly propagated up to the nip point on the delivery rollers 3, 4.
  • the fact that there is no twist reduction due to the constriction 220 creates stable spinning conditions which result in good yarn strength.
  • the wrapping fibers that lie around the yarn core can be generated in a targeted and controlled manner by the width of the fiber sliver emerging from the drafting device.
  • the inner fibers can be wrapped well by the outer fibers of the yarn and thus good yarn strength can be obtained.
  • the thread Due to the large inner diameter A of the injector part, the thread is fed to the twist part 2 in such a way that a good rotation can take place. With that they have through the Air inlet bores 200, 210 air flows acting on the thread part have a large lever arm.
  • a particularly good way of twisting the thread has been to arrange the air inlet bores 200, 210 at right angles in their projection to the axis of the twist part 2.
