Definitions

  • the present invention relates to a method for producing spinnable synthetic yarn with a melt spinning process to produce a filament yarn or one a variety of filament yarn existing filament cable, which is spooled or stored in a container and fed to a tear conversion process is in which the filament yarn or filament cord stretched and torn into staple fibers and the filament yarn or sliver thus formed is solidified.
  • polyester is a synthetic fiber made from linear macromolecules with a chain with at least 85% by mass of diol and terephthalic acid.
  • the first Polyester was made in 1941; it is known and manufactured as polyethylene terephthalate (PET) the most important synthetic fiber in terms of quantity.
  • PET polyethylene terephthalate
  • the one used in the melt spinning process Melt is extruded into an endless filament and wound onto tubes or in the form a filament cable consisting of a plurality of filament fibers in a suitable one Container filed.
  • the production of polyamide fibers is very similar.
  • the concerned Manufacturing machines are called filament spinning machines.
  • Tear conversion involves several process stages in which the filaments / chemical fiber cables first stretched and then torn by further stretching. The Elongation occurs essentially by being driven at different speeds Pairs of rollers.
  • a mixer or a ring or rotor spinning machine is available.
  • the yarn speed in the tear converting device is relatively low and is only one Fraction of the yarn speed on the filament spinning machine.
  • the Rice conversion is a separate process that involves additional processing steps (Transport of the filament yarn / filament cable to the tear converting device, loading of the the latter, removal of the staple fiber tape from the tear converting device). All these boundary conditions make the production of the synthetic yarn more expensive.
  • the known process for the production of spinnable Synthetic yarn can be improved so that there is a significant cost reduction.
  • the object is achieved according to the invention in that the tear conversion process is integrated in the process of producing the filament yarn or filament cable.
  • the invention further relates to a filament spinning machine with a melt spinning device for producing a filament yarn or one of a plurality of filament yarns existing filament cable.
  • the filament spinning machine according to the invention is characterized through an integrated rice converter.
  • a first preferred embodiment of the filament spinning machine for the production of a filament yarn with at least one stage for stretching the filament yarn and a winding stage for this is characterized in that the tear converting device between the melt spinning device and the at least one stage for Stretching the filament yarn is arranged.
  • the tear converter is between the two stages arranged to stretch the filament yarn.
  • a second preferred embodiment of the filament spinning machine for the production of a filament yarn with at least one stage for stretching the filament yarn and a winding stage for this is characterized in that the tear converting device is arranged immediately before the winding stage.
  • a third preferred embodiment of the filament spinning machine for the generation of a filament tow with at least one step for stretching the filament tow and a stage for its crimp is characterized in that the tear converting device between the melt spinning device and the at least one stage is arranged to stretch the filament cable.
  • Another preferred embodiment of the filament spinning machine according to the invention is characterized in that the tear converter three with different Has speed driven roller pairs and a consolidation member, the three Roller pairs delimit a first and a second crushing zone and the consolidation member is formed by a swirl nozzle.
  • the reference numeral 1 is a container with a polyethylene terephthalate melt or Designated polyamide polymer melt, which then a spinning unit 2 for Production of a filament yarn 3 (left half of the drawing) or a spinning unit 4 for the production of a filament cable 5 (right half of the drawing) is supplied.
  • the filament spinning machine shown in the left half of Fig. 1 for the manufacture of a Filament yarn 3 also contains a winding stage 8 and optionally a treatment device 6, the structure of which depends on the nature of the end product.
  • the Treatment device 6 at least one, as shown two, stretching stages 7, 7 ' for stretching the filament yarn 3. All of these processes can be done in one or one Multi-stage process, or in other words, continuously or discontinuously become.
  • the filament yarn 3 is to be spun, it has to be torn into staple fibers, what has been done so far in a separate tear converter 9 of the type shown in FIG. 2.
  • a separate tear converter 9 of the type shown in FIG. 2.
  • the polyester or polyamide filament yarn wound on the spool 8 is stretched, torn into staple fibers and consolidated into a spinnable tape.
  • the stretch and that The filament yarn 3 is torn by being driven at different speeds Roller pairs 10, 11 and 12.
  • roller pairs 10, 11 and 12 Between the running direction indicated by an arrow A. the yarn 3 rear and the middle pair of rollers 10 and 11 is an expansion zone or first Crushing zone BZ1 and between the middle pair of rollers 11 and in the direction of yarn front roller pair 12, a second crushing zone BZ2 is formed.
  • a solidification zone VZ which is a means of solidifying the through the Tearing the filament yarn has 3 staple fibers formed. This means is preferred formed by a swirl nozzle 13.
  • Numeral 14 is a pair of Transport rollers called.
  • the filament spinning machine shown in the right half of Fig. 1 for manufacture one consisting of a plurality of filament yarns 5 additionally contains for the melt spinning unit 4 a treatment device 6 'and a container 17 for storage of the filament cable 5.
  • the filament cable 5 is stretched, crimped and to the desired Cut stack length.
  • the filament cable is used to produce long fiber staple yarn stretched, crimped and in the container formed by a jug or a box 17 filed. All of these processes can be done in a single or a multi-stage process, or in other words, continuously or discontinuously.
  • That in the container 17 deposited filament cable can then be connected to a tear converter of the type shown in FIG. 2 shown type or a converter where it is cut. In both In some cases there is a sliver at the exit of the tear converter or converter synthetic staple fibers.
  • the tear converting device 9 is integrated in the filament spinning machines, which means that the conversion of the rice is not a separate process with additional yarn handling represents more and also with the yarn transport speed usual in the filament spinning machine expires, so that there is a not inconsiderable reduction in effort.
  • the filament spinning machine shown in Fig. 1 has the main advantage that it is an end product a spun yarn delivers which can be spun without any further treatment.
  • the Integration of the rice conversion in the melt spinning process leads to a triple Cost reduction: On the one hand, there is the rice converting device integrated in the melt-spinning process cheaper than a separate tear converting device separate from the melt spinning process and on the other hand, that associated with the separate tear conversion device is eliminated Handling the yarn. And third, the entire yarn manufacturing process is from Melt-spinning process shortened to the spun synthetic yarn.
