Definitions

  • Blended yarns are known in which one component consists of synthetic filaments and the other component consists of spun natural fibers.
  • synthetic filaments e.g. strength, low price
  • natural fibers e.g. handle and wearing properties of products made from them.
  • a process for producing a mixed yarn is described in which a false twist textured filament yarn with a carrier yarn, e.g. a staple fiber yarn made from natural fibers.
  • twisting or twisting is required, which limits the production speed of the mixed yarn.
  • a blended yarn which, according to US-A-4196 574, can be produced by combining a filament yarn coming directly from a false twist texturing device with a spun yarn in an air swirl nozzle.
  • the filament yarn coming directly from the false twist texturing device not only offers good conditions for interweaving with the spun yarn, but it also tends to contract in the mixed yarn when the tension is relaxed, with the spun yarn, which cannot contract, between the interweaving points is laterally bent out so that the spun yarn fiber structure clearly stands out.
  • this method has the disadvantage that it is not possible for the false twist texturing device and the air swirling nozzle to operate at optimum speeds at the same time, because the filament yarn passes through both devices immediately one after the other.
  • the object of the invention is to avoid these disadvantages and to provide a method for producing a mixed yarn from at least one false twist-textured filament yarn and at least one spun-turned staple fiber yarn in an air vortex nozzle, in which the working speed of the air vortex nozzle can be freely selected, but nevertheless the filament yarn can be processed -slide-resistant with the staple fiber yarn. can be braided and can contract in the finished mixed yarn in the desired manner, so that the staple fiber yarn is bent out laterally between the interlacing points.
  • the object is achieved according to the invention in a method of the type specified in the preamble of patent claim 1 in that the false-twisted textured filament yarn is first stretched for the ripple reactivation after being pulled off the bobbin before it is delivered to the air vortex nozzle with the release which causes a ripple under relaxation is fed.
  • the air swirl nozzle is simultaneously a stretched auxiliary thread made of elastomer fibers, e.g., the filament yarn and the staple fiber yarn.
  • a polyurethane thread is fed, which is also interwoven with these yarns at the points of interweaving between filament yarn and staple fiber yarn.
  • the purpose of the elastic auxiliary thread is to increase the crimp contraction behavior of the false twist-textured filament yarn and thus to considerably increase the bulk and the elastic behavior of the mixed yarn.
  • FIG. 1 schematically shows a method for producing a blended yarn.
  • Two false twisted textured filament yarns 1 and 1 'made of synthetic, thermoplastic continuous filaments, a spun-turned staple fiber yarn 2 made of natural fibers of plant and / or animal origin and a rubber-elastic polyurethane thread 3 are passed together through an air vortex nozzle 10 of known type and intertwined in places in this.
  • the air swirl nozzle 10 has in the usual way an axial passage channel through which the fila ment yarns 1 and 1 ', the staple fiber yarn 2 and the polyurethane thread 3 are passed together.
  • Air-blowing ducts open laterally into the axial passage duct.
  • the mixed yarn 4 thus formed is wound up in a winding device 11.
  • the staple fiber yarn 2 is supplied by a delivery unit 12 into the air swirl nozzle 10 with a defined speed and a desired tension.
  • the feed mechanism 12 draws the yarn 2 from a bobbin 14 via a thread brake 13.
  • the filament yarns 1 and 1 ' are supplied to the air swirl nozzle 10 by a supply unit 15.
  • the delivery unit 15 draws the yarns 1 and 1 'from two spools 17 and 17' via a thread brake 16 or 16 ', preferably an adjustable hysteresis brake.
  • the false twist-textured filament yarns 1 and 1 ' are stretched between the feed mechanism 15 and the thread brakes 16 and 16', preferably by about 3 to 10% or with a tensile force of about 0.7 to 2.6 cN / dtex, and experienced thereby a ripple reactivation.
  • the delivery unit 15 delivers the filament yarns 1 and 1 'with a preselected delivery to the air vortex nozzle 10, for example with an delivery of about 5 to 10%, based on the speed of the staple fiber yarn 2.
  • the filament yarns 1 and 1' are thereby between the delivery unit 15 and the air vortex nozzle 10 relaxed so that they can fully ripple.
  • the filament yarns are brought into a state in which they can be optimally interlaced in places in the air vortex nozzle 10 with the staple fiber yarn 2, so that the interlacing points produced are sufficiently resistant to processing and sliding.
  • the filament yarns 1 and 1 'crimped in the manner described then have the tendency to contract and to bend the staple fiber yarn 2 laterally between the interlacing points, so that the natural fiber structure in the mixed yarn clearly emerges.
  • a polyurethane thread 3 When a polyurethane thread 3 is used, it is supplied by an unwinding device 18 at a speed which is lower than the speed of the staple fiber yarn 2. The polyurethane thread 3 is therefore brought together with the staple fiber thread 2 in the stretched state. However, the polyurethane thread 3 and the unwinding device 18 can also be omitted.
  • a cotton yarn N m 60/1 is used as the staple fiber yarn 2, which is supplied by the delivery unit 12 at a speed of 500 m / min. is supplied into the air swirl nozzle 10.
  • the winding device 11 causes a tensile force of 10 cN in the yarn 2.
  • filament yarns 1 and 1 ' two highly elastic false twist textured polyester yarns dtex 78 f 34 HE (Z) are used, which are stretched between the thread brakes 16 and 16' and the feed unit 15 with a tensile force of 55 cN each.
  • the delivery unit 15 conveys the filament yarns at a speed of 540 m / min. to the air swirl nozzle 10.
  • the polyurethane thread 3 is a “elastane” thread dtex 45, which is taken from the unwinder 18 at a speed of 150 m / min. is delivered.
  • a cotton yarn N m 30/1 is used as the staple fiber yarn 2, which is supplied by the delivery unit 12 at a speed of 400 m / min. is supplied into the air swirl nozzle 10.
  • the thread tension is 12 cN.
  • two highly elastic false twist-textured polyester yarns dtex 167 f 34 HE (Z) are used, which are stretched between the thread brakes 16 and 16' and the feed mechanism 15 with a tensile force of 160 cN each and by the feed mechanism 15 a speed of 428 m / min. are delivered to the air swirl nozzle 10.
  • the polyurethane thread is omitted in this example.
  • the staple fiber yarn 2 is a cotton yarn N m 60/1, which at a speed of 300 m / min. is drawn through the air swirl nozzle 10.
  • the thread tension is 8 cN.
  • the filament yarn 1 is a highly elastic false twist textured polyester yarn dtex 78 f 34 HE (Z), which is stretched between the thread brake 16 and the feed mechanism 15 with a tensile force of 65 cN and from the feed mechanism at a speed of 318 m / min. is delivered to the air swirl nozzle 10.
  • FIG. 2 schematically shows a preferred arrangement of the device parts described with reference to FIG. 1.
  • the device shown in Fig. 2 has two creels 20 and 20 ', in which the coils 14 and 17 and 17' are housed.
  • a winding machine 21 is arranged directly in front of the creel 20, to which the thread brakes 13 and 16, the delivery mechanisms 12 and 15, the air swirl nozzle 10 and the winding device 11 belong.
  • the unwinding device 18 for the polyurethane thread 3 can also be arranged on the winding machine 21.
  • the arrangement of the winding machine 21 directly in front of the creel 20 has the advantage that the two can be assigned a common suction device, which has a suction nozzle for the fiber fly both in the winding device 11 of the winding machine and in the staple fiber yarn bobbin 14 in the creel 20.
  • the device can of course have a large number of work stations of the type described.
  • a mixed yarn is shown as it can be produced in the manner described from a false twist-textured filament yarn 1 and a staple fiber yarn 2 by means of an air swirl nozzle.
  • the filament yarn 1 and the staple fiber yarn 2 are interlaced at spaced-apart locations V in a manner that prevents them from sliding during processing, while they are between the interlacing put V bundled next to each other.
  • the distance between two adjacent interweaving points V in the stretched state of the blended yarn, that is under a load of 0.3 cN / dtex, as shown in FIG. 3, is denoted by I x .
  • the average distance l x is 5 to 50 mm, depending on the type of air vortex nozzle used, the pressure of the blown air supplied, the tension of the staple fiber yarn passing through the air vortex nozzle and the size of the delivery with which the false-twisted textured filament yarn is fed to the air vortex nozzle .
  • the interlacing points V are distributed approximately uniformly or at irregular intervals l x over the length of the blended yarn.
  • Fig. 4 the blended yarn of Fig. 3 is shown in the unstretched state, that is under a load of 0.0005 cN / dtex.
  • the filament yarn 1 has contracted.
  • the staple fiber yarn 2, which practically cannot contract, is thereby laterally bent out at the unbound points between the interweaving points V.
  • the distance between the axis of the filament yarn 1 and the axis of the bent staple fiber yarn 2 at the point farthest from the axis of the filament yarn 1 is denoted by ly.
  • the distances ly are on average at least 10% of the mean distance I x according to FIG. 3.
  • auxiliary thread 3 made of elastomer fibers, e.g. contains a polyurethane thread.
  • the auxiliary thread 3 is also intertwined with the two yarns 1 and 2 and held in the same.
  • the spacing of the interweaving points V is reduced by the elastic force of the auxiliary thread 3.
  • the staple fiber yarn 2 is therefore laterally bent out between the interlacing points V, as a result of which the bulk of the mixed yarn is considerably increased.
