Definitions

  • the invention relates to a device for interlacing multifilament yarns according to the preamble of claim 1.
  • the object of the invention is to design this device in such a way that, in comparison with known devices, a more uniform interlacing of multifilament yarns, in particular more uniform distances between the successive interlacing points, and a higher interlacing density, measured in interlacing points per meter, can be achieved. Furthermore, the formation of many and regular strong swirling points per meter or the formation of many and regular weak swirling points per meter should be possible, as desired.
  • the object is achieved in the device according to the invention in that the two wall surfaces are curved so convexly on average with the plane of symmetry that the distance between the two wall surfaces measured in the plane of symmetry gradually decreases from a minimum at the mouth of the blowing nozzle towards both ends of the yarn channel increases.
  • the energy of the fluid usually air, supplied through the blowing nozzle and flowing out through the yarn channel, has an adverse effect on the intermingled yarn, for example by dissolving weak intermingling points and thereby making the intermingling irregular and at the same time reducing the intermingling density.
  • the thread tension in the yarn section moving past the mouth of the blow nozzle is additionally increased by the fluid flowing out toward both ends of the yarn channel, which makes the intermingling more difficult.
  • Document DE-A-2917218 describes a generic intermingling device in which the one wall surface of the yarn channel, in which a blowing nozzle opens, is convexly curved in the plane of symmetry. This is supposed to be achieved that the yarn can be passed over the mouth of the blow nozzle in a non-linear way.
  • both wall surfaces of the yarn channel are convexly curved in the plane of symmetry.
  • the distance measured in the plane of symmetry between the two wall surfaces toward the ends of the yarn channel can increase more with the same radius of curvature than with only one curved wall surface.
  • Swirling devices are usually designed in such a way that in the vicinity of the mouth of the blowing nozzle only an insignificantly higher pressure than the ambient pressure prevailing outside the device is formed. This is the only way to effectively use the energy gradient in the device.
  • the velocity of the outflowing medium has to be reduced because the enlargement of the cross-sectional area towards the ends of the yarn channel gradually takes place so that the flow does not detach from the walls of the yarn channel.
  • the width of the yarn channel preferably remains essentially constant over the entire length of the yarn channel. Maintaining the optimal yarn channel width results in a better quality of the interlacing and in particular a high swirl density.
  • the blow jet divides the filament bundle into two approximately equal-sized bundles when they are pressed against the second wall surface, which only come together again at a certain distance from the blower nozzle to the intermingling nodes forming on both sides of the blower nozzle mouth. A further spreading of the two filament bundles in a yarn channel, which would widen towards the ends, would cause the swirl knots to form further away from the blow nozzle. This would reduce the turbulence density and the distance between the turbulence points would be greater.
  • a device for intermingling multifilament yarns has a two-part body with a nozzle body part 1 and a baffle body part 2, which is attached to the nozzle body part 1 interchangeably by means of a screw 3 and two centering pins 4 and 5.
  • a continuous yarn channel 6 extends through the two-part body 1, 2 and is delimited by a first wall surface 7 with a concave cross section, formed by a groove in the nozzle body part 1, and by a second hollow wall surface 8, formed by a groove in the impact body part 2
  • the two wall surfaces 7 and 8 are each symmetrical with respect to a plane of symmetry which is identical to the sectional plane AA in FIG.
  • the nozzle body part 1 contains a blowing nozzle 9, which is approximately in the middle the length of the yarn channel 6 opens laterally into the yarn channel.
  • the mouth of the blowing nozzle 9 lies in the first wall surface 7.
  • the second wall surface 8 lies opposite the opening of the blowing nozzle 9.
  • the axis of the blowing nozzle 9 suitably lies in the plane of symmetry A - A.
  • the nozzle body part 1 could also contain more than one blow nozzle.
  • each blowing nozzle could be symmetrical with respect to the plane of symmetry A - A or, for example, two blowing nozzles could also be arranged symmetrically to one another on both sides of the plane A - A.
  • the first wall surface 7 and the second wall surface 8 are curved in section with the plane of symmetry A - A as shown in FIG. 3 such that the distance between the two wall surfaces 7 and 8 measured in the plane of symmetry A - A is at a minimum at the mouth the blowing nozzle 9 gradually increases towards both ends of the yarn channel 6.
  • the width of the yarn channel 6 measured perpendicular to the plane of symmetry A - A remains constant over the entire length of the yarn channel
  • the cross-sectional area of the yarn channel increases from a minimum size at the mouth of the blowing nozzle 9 towards both ends of the yarn channel, for example except for 1.2 to 4 times the minimum size, preferably 1.5 to 2 times the minimum size.
  • the curvature of the first wall surface 7 extends in such a way that the flow of the blowing medium from the mouth of the blowing nozzle 9 to the ends of the yarn channel 6 does not detach from the wall surface 7.
  • the curve has no kinks, which means that the first derivative of the function mentioned is also a continuous function.
  • the curvature of the curve should preferably not change abruptly; in other words, the second should also Deriving the function represented by the curve should preferably be a continuous function (without jumps).
  • the second wall surface 8 is curved on average with the plane of symmetry.
  • the curvature of the second wall surface 8 runs continuously in the same way as described above for the first wall surface 7, so that the flow does not separate from the second wall surface 8 either.
  • a continuous threading slot 10 opens laterally into the yarn channel 6 between the two wall surfaces 7 and 8.
  • the threading slot 10 lies between flat surfaces of the nozzle body part 1 and the impact body part 2.
  • the yarn channel 6 ends at both ends in a groove 11 or 12.
  • thread guide pins 13 or 14 are inserted outside the ends of the yarn channel, e.g. Sapphire pins that extend across grooves 11 and 12, respectively.
  • a multifilament yarn M (FIG. 3), which in operation runs through the yarn channel 6 and is swirled by the blowing medium entering the yarn channel 6 from the blowing nozzle 9, is guided very precisely in the yarn channel 6.
  • the thread guide pins have not been shown in FIG. 4.
  • the second wall surface 8 extends beyond the ends of the yarn channel 6 to the outside.
  • the first wall surface 7 is approximately V-shaped in cross-section with a rounded transition between the two V-legs. In other embodiments, the first wall surface could be approximately semicircular in cross section. Furthermore, the threading slot 10 could be omitted if desired.
