Definitions

  • the invention relates to a method for the production of knotted yarn or twist yarn of DTY (Draw Twist Yarn) and / or smooth yarns with high regularity of knots by means of air nozzles with a Gam aspectskanal and blowing air, which is injected transversely to the Gam aspectskanal, the blast air in Garn practicecardi and against the Garn practicecardi ever a double vortex for generating the node forms.
  • the invention further relates to a Verwirbelungsdüse for the production of knot yarn with high regularity of the nodes with a continuous Gam aspectskanal and a Blasluftzuzuzenkanal, wherein the Blas povertyzuchtkanal is directed to the longitudinal center axis of the Garn analogskanales.
  • microfilaments In the recent past, increasingly finer filaments have been produced. These are called microfilaments when the denier per filament (dpf) is between 0.5 and about 1.2.
  • the game made of it is called Microfilamentgame.
  • supermicrofilaments are included unless otherwise noted.
  • Already yarns with a dpf over 1.2 require gentle processing, so that neither single filaments nor the whole yarn breaks. To an even greater extent, this applies to the microfilament games.
  • DTY-Game means "Draw Twist Yam", in English: false twist texture yarns.
  • the DE 197 00 817 shows a special form of a Verwirbelungsdüse for carpet yarn, so for very rough BCF game. It was assumed that a process for the continuous production of spun-textured filament yarns in a continuous yarn channel or vortex channel of a vortex nozzle.
  • the filament yarn is directed through a transversely directed into the vortex nozzle and forward and backward from the Whirled yarn channel outflow blowing air flow and discharged the exhaust air of the backward vortex approximately in the opposite direction to the Blas Kunststoffzu entry from the Garneinlomi Scheme.
  • the forward swirl is designed to be more effective than the backward swirl.
  • the DE 37 11 759 Starting from finer to medium yarns and trying to improve the processability of the game in subsequent processing, such as weaving, knitting, knitting and tufting machines.
  • the inventor started out from a swirling device for swirling multifilament yarns which has at least one yarn channel, wherein yarn guides are arranged at intervals from the inlet and outlet mouth of the yarn channel and the filaments of a respective multifilament yarn can be swirled in the yarn channel by means of a blowing nozzle.
  • the yarn undergoes a change in direction of less than 90 ° when entering and leaving the yarn channel, and the blowing angle of the blowing nozzle is less than 90 °.
  • the yarn guides are arranged so that the yarn is applied to the Gamkanal with the compressed air supply off so that it extends in the yarn channel parallel to its longitudinal direction and thereby rests against the outlet mouth of the at least one tuyere.
  • the distance of the Gamterrorism is from the Gamkanalmünditch adjacent to them a maximum of 30 mm.
  • the length of the yarn channel is a maximum of 40 mm for uncrimped multfilament yarns and a maximum of 30 mm for crimped multifilament yarns.
  • a yarn channel length is proposed for textured or crimped yarns of 10-28 mm. In particular, the range of 10 mm yarn channel length is understood to be short.
  • the method according to the invention is characterized in that the blown air in the entry region into the yarn treatment channel in an air swirl chamber is displaced into two strong stationary air swirl flows, which are almost undisturbed by filament bundles.
  • the swirling nozzle according to the invention is characterized in that a blown air duct extension is formed in the mouth region of the blown air supply duct in the yarn treatment duct to form an air swirl chamber for two counter-rotating stationary air swirl flows, whereby the blown air duct extension exceeds less than 22% but more than 5% of the yarn duct width.
  • Vortex chamber As Vortexchamber is understood a relatively large extension of the yarn channel before and after the area of the Lucaseinblasstelle. The goal was to give the yarn or individual filaments the opportunity to oscillate within the vortex chamber.
  • the new invention seeks an improvement on the air side. It is proposed an air-twist-chamber or Microwirbelhunt for the air. It is true that the node stability could be increased with the vortex chamber. However, this is at the expense of the number of nodes. There are fewer knots per meter of yarn produced. The individual nodes are longer.
  • an air swirl chamber is mounted in the inlet region of the blowing air in the yarn treatment channel, so that the air flow is placed at the relevant point in two strong undisturbed swirling flows.
  • the air swirl chamber is a miniature blast air duct extension and forms a transition between a completely stable swirl flow in the area of the air injection and the subsequent just as completely unstable vortex zone to the exit from the yarn channel.
  • the air swirl chamber is designed miniaturized such that the yarn bundle can not completely penetrate into the lateral extension of the air swirl chamber.
  • the air swirl chamber protrudes only a fraction of a millimeter, the Garnkanalwand. For example, for a 1.6 mm wide yarn channel a maximum width of the air chamber of 2.2 mm proposed. It was initially completely surprising to all those involved that such a small measure could be used to achieve correspondingly large effects. However, the explanation lies in the targeted design of the supersonic air flow.
  • the new invention could be examined with large series of tests with DTY yarns (false twist yarns). The results were good for fine, medium and coarse yarns. The results were most surprising in fine yarns, especially microfilament yarns. First attempts with plain yarns were positive, although the result was less pronounced in relation to DTY-Gamen. At least on the basis of theoretical considerations, the new invention can also be used in BCF yarns, in the BCF-Gamen due to the much larger yarn channel widths of up to 8 mm, the air swirl chamber is to survive at most 22%, at least 5% of Gamkanalbreite.
  • the new invention also allows for a number of advantageous embodiments of the yarn swirling nozzle. It is proposed to form the Gam harmonysquerrough half round or U-shaped and with a flat baffle.
  • the air swirl chamber is laterally shaped as a miniaturized dome with respect to the Gam oppositionskanat cross section, wherein the air swirl chamber on both sides of the Gam oppositionskanales protrudes less than 0.5 mm.
  • the Studentsstehmass of smaller 0.5 mm could be confirmed with yarns up to 500 denier, so with Gamkanalbreiten up to 3 mm.
  • the Process for larger yarn channel widths over 3 mm an overfeed pass of less than 22% and more than 5% of the yarn channel width is required.
  • the Sprinthmass is between 10% and 20% of the yarn channel width.
  • the air swirl chamber further preferably has an approximately circularly symmetrical outer contour and forms a continuation of the center axis of the Blas Kunststoffzuzenkanales.
  • the width of the Gamkanalqueriteses is greater than the Garnkanalianae formed in the direction of Blas Kunststoffzussel to intensify the lateral vortex formation.
  • the treatment channel can be formed as a wide channel with a width of preferably 0.6 to 3 mm, particularly preferably with a ratio of yarn channel width (B) to yarn channel depth (T) of 1.2 to 2.5.
  • the length of the air swirl chamber was preferably smaller than 1.3 of the yarn channel width.
  • the length of the air swirl chamber is about 0.7 to 1.6, preferably 0.8 to 1.2 with respect to the width of the Gamkanales, which is substantially below the L / B ratio of about 1.75 of the prior art Technology is.
  • the blown air supply channel is round or oval or oval with a triangular character or Y-shaped, wherein the side dimension of the Blas Kunststoffzuchtkanales is at most equal to or less than the corresponding Gamkanalbreite.
  • the yarn channel width (B) is made larger than the Heilzuchtkanalbrefte d, preferably in a ratio B / d of 1.1 to 3.
  • the yarn channel is formed by a plane displaceable baffle plate and a nozzle plate with the blown air supply.
