Definitions

  • the invention relates to a method for producing technical filament yarns by swirling one Polyester multifilaments at elevated temperature, below a thread tension of less than 140 cN, in one air swirling nozzle, consisting from a nozzle body with a perforated plate and one Baffle plate, and a device for carrying out the Process and a technical filament yarn.
  • Multifilament yarns are swirled during the spinning process, to interweave the individual filament fibrils received and to spread threads during further processing to avoid.
  • the intertwining occurs selectively, enables an improved cohesion of the Single filaments in the fibril dressing and a better one Further processability of the yarn.
  • Technical filament yarns made of polyester in particular those whose manufacturing process is characterized by low Winding thread tension of less than 100 cN are marked, in a total titre range of 500 up to 2000 dtex tend to form Deposits in the swirl nozzle.
  • Cold air swirling such as that of EP-A-0 148 402 describes, can be a commercially available, open Swirling nozzle with perforated and baffle plate up to max. 24 hours in operation. Then the Nozzle mechanically and in a complex process can be dry cleaned.
  • the object of the invention is a simplified method to create a better knot distribution and extended nozzle life allowed.
  • Another task is to create a swirling device to provide the energy consumption the process of swirling is reduced.
  • the object is achieved in that the heat on the polyester multifilament and the air over the nozzle body onto one directly with the Baffle plate connected high heat conductive metal block is transmitted directly, in which a hole for the Inclusion of a radiator is provided. It will thereby an improved spreading and node distribution, as well as an enormous energy saving of 85% reached.
  • the swirl nozzle as a cold point in the Spinning process is eliminated.
  • the baffle plate It is advisable to keep the baffle plate at a constant Temperature between 150 and 180 ° C, especially 150 ° to 170 ° C, preferably 160 ° C to heat. A temperature below 150 ° C has the disadvantage of increasing deposits; at a temperature above 180 ° C improve Swirl properties no further.
  • the device for performing the method exists from a swirling nozzle with a nozzle body, one Perforated plate and a baffle plate.
  • the baffle is expediently direct and flush with a highly thermally conductive Metal block, for example made of aluminum connected in which a hole for receiving a Radiator is provided.
  • radiators are electric resistance heaters or any other suitable for space-saving heating. It is essential direct contact between the baffle plate and the Metal block.
  • a manufactured according to the inventive method Polyester filament yarn, with a winding tension less than 140 cN, especially less than 100 cN and with a total titer of 500 - 2000 dtex in addition to a strength of at least 70 cN / tex, at an elongation at break of less than 24%, an increased Knot resistance greater than 80% and one Distance between 2 knots greater than 4.0 cm.
  • the Polyester filament yarn is excellent for Manufacture of coated fabrics for industrial Suitable purposes.
  • Fig. 1 an inventive swirling nozzle in Side view.
  • a nozzle body with the Reference number 1 denotes.
  • the nozzle body 1 is over a perforated plate 2 connected to a baffle plate 3.
  • a compressed air line 4 via a Bracket 5 attached.
  • a gap is provided, the passage for a thread F from a thread guide 6 to one Thread guide 6 'guaranteed.
  • a metal body 8 is provided flush with Mounting screws 9, 9 'is attached to the perforated plate 2.
  • the metal body 8 is with a bore 7 for receiving a radiator provided.
  • the nozzle described in FIG. 1 was pressurized in a known manner via the compressed air line 4 with commercial, cold compressed air of 1.8 bar.
  • a constant temperature level of 160 ° C on the baffle plate 3 could be maintained for 80 hours with the radiator with a heating power of 50W / 50V.
  • Table 1 shows the results achieved in comparison with the known hot air swirling. variant Type of swirl Course of time (h) Swirling (kn / m) Verwirb.
  • the table shows that after a Operating time of 80 hours a swirl of 12.1 Knots / m (target value: 12.0 ⁇ 1.5) with a spread of 0.36 and a turbulence stability of 87.1% achieved become.
  • the swirling nozzle according to the invention was used during 96 Hours with a baffle plate temperature of 160 ° C used.
  • the standard air pressure of 2.8 bar corresponds that of hot air swirling.
  • Table 2 shows the results achieved in comparison with the known hot air swirling.
  • Time h Type of swirl Düs.

  • the hot nozzle swirl brings in comparison with the known hot air swirling with the same nozzle operating time an equally good swirl value, one good knot resistance and a much better one Node distribution.
  • the smallest distance between 2 knots increased by at least about 15% from 3.4 4 cm.
  • the serimetric properties and the Thread cleanliness remained unchanged.
  • the method according to the invention is particularly suitable for the production of high-strength industrial yarn for fabrics for tents, tarpaulins and geotextiles, as a rule be coated.
