Definitions

  • the invention relates to a method for pre-intermingling a partially drawn polyester POY, original yarns for the drawing, texturing and / or drawing texturing process by means of an air intermingling nozzle for producing a textile yarn or plain yarn for textile fabrics and the yarn produced by the process.
  • a swirling process is known, according to which an undrawn or partially stretched original yarn, for a false twist texturing process, is swirled weakly at an air pressure of approximately 0.5 bar, in order to avoid the actual texturing process due to too intensive swirling points in the form of knots disturb.
  • the knots created in the original yarn must dissolve again during the further processing of the yarns in order to avoid defects.
  • the object of the known method is to reduce thread breaks, particularly in the case of fine-fibrillated yarns. After texturing, these are yarns then swirl again, whereby the thread closure of the textured yarn produced here has the same task as for the original yarn, namely the improvement or the guarantee of further processability.
  • the swirling points according to the known method have the disadvantage that they disrupt the uniformity of the product image, especially in the case of fine titers. So far, it has not been possible to weave sufficiently interwoven textured yarns for a smooth bobbin run-off without giving up an uneasy product appearance.
  • a method for the simultaneous stretch texturing of partially stretched polyamide yarns is also known, with swirling using an air swirling nozzle before entering the texturing zone (FR-A-22 96 710).
  • the swirling takes place with an air pressure of at least 2.5 bar, 100-1000 swirls / m, preferably more than 300 swirls, being aimed for.
  • a strong intermingling in the master yarn has the disadvantage, however, that with polyester POY the knots are only partially dissolved during texturing. The result is an insufficient uniformity of the crimp, which leads to a clear drawing in the tissue.
  • the object of the invention is to provide a method which ensures good thread closure in a textured or stretched filament yarn, ensures problem-free bobbin flow during further processing and enables a fabric which is as free of drawings as possible.
  • the invention serving to achieve the object is characterized in that the feed yarn is swirled at an air pressure of 0.5 to 2.0 bar.
  • the intermingling takes place before the yarn enters the texturing device at an air pressure in the nozzle body of 0.5 to 2.0 bar.
  • the pre-interlaced yarn which is both a textured yarn and a plain yarn can have a "continuously" swirling characteristic.
  • continuous swirling denotes a type of swirling that has no pronounced swirling points, in contrast to the known swirling, for which clearly visible nodes are characteristic at periodic intervals.
  • the number of fluff also reaches a minimum of approximately 80 fluff per 100,000 m of yarn length and provides a drawing-free product image in a fabric.
  • Fluff means broken filaments and / or thread elements protruding from the thread core.
  • the fluff was measured using a TORAY measuring head, which works on the electro-optical principle.
  • the test speed was 1000 m / min, the tested yarn length per variant 1.6 x 105 m.
  • a polyester POY with a titer of nominally dtex 100 f 72 was used as the feed yarn.
  • Closed 2-hole nozzles for example with an air duct diameter of 0.7 mm, are best suited as interlacing nozzles.
  • other commercially available swirling nozzles can also be used, which ensure a constant pressure in the stressed area.
  • the texturing was carried out at 500 m / min on an FK6-CF texturing machine from BARMAG AG.
  • the intermingling increases continuously to 65 knots / m at an air pressure of 2.5 bar.
  • the number of knots is far below that of a yarn normally intermingled at 2.5 bar, without the bobbin winding deteriorating.
  • the swirling takes place in a known manner following the texturing before winding.
  • a polyester POY with a titer of nominally dtex 167 f 36 octolobal was used as the original yarn by the method according to the invention.
  • the test results are summarized in Table 2. The same tendencies can be seen in the bobbin winding behavior, the number of knots and the fabric image.
  • the textured yarn produced by the method according to the invention results in a perfect fabric appearance of the fabric, since obviously only a sufficient dissolution of the applied swirling points occurs during the texturing process that the remaining swirling comes close to a so-called "continuous" swirling.
  • An advantage of the quasi-continuous interlacing is above all the low drawing in the fabric with at the same time sufficient thread closure for perfect processing.
