Definitions

  • the invention relates to a method for producing monofilaments from polyester with a round Cross section in a titer range of 5 - 25 dtex.
  • the filaments according to US-A-3,832,435 are crimped multifilaments. in the Procedure requires two cylinders. A larger cylinder is a much smaller cylinder downstream. The first cylinder is used to cool the filaments, the second cylinder runs with one different speed than the first and serves to stretch the filaments. The speed of circulation of the first cylinder is a maximum of 470 m / min, that of the stretching roller is a maximum of 1000 m / min, GB-A-12 68 302 describes a process for producing crimped polyamide multifilaments described. In it, cooled godet pairs are provided, with which the multifilaments in one Stretched and then wound up. According to the known method Speeds limited to 1250 m / min.
  • Fine monofilaments up to about 33 dtex are spun at spinning speeds below 1000 m / min, cooled with blown air, wound up and separated in a second operation at about 750 m / min stretched.
  • the object of the invention is to provide a method for producing fine monofilaments to provide the properties of. without separate stretching process at high winding speeds known monofilaments achieved and / or improved.
  • Another object is to vary the process so that desired properties of the Monofilaments can be achieved through the setting parameters of the device.
  • the aforementioned object is achieved in that the melt-spun Filaments passed over a single air-cooled rotating roller, prepared for spinning and directly with a Speed of 4000 to 6000 m / min can be wound up, the monofilaments over the with a Circumferential speed of 1000 to 1600 m / min rotating roller.
  • roller as a cooling element, it is possible for the first time to load monofilaments Spin titer range at high speeds. It is also particularly advantageous that the Single-stage process, i.e. can be carried out without additional drafting equipment. So the process is very uncomplicated and offers appropriate variation of the roller parameters, such as peripheral speed, Distance from the spinneret roller and cooling time are a simple prerequisite for influencing the Monofilament properties.
  • the circumferential speed of the copper roller is expediently dependent on 1000 to 1600 m / min to choose from titer.
  • the thread properties can also be influenced.
  • the thermal treatment then takes place integrated at 110-200 ° C, in particular at 150-170 ° C, preferably at 150-160 ° C.
  • the thermal treatment can be achieved especially with fine monofilaments the properties of the invention may be useful.
  • the roller consists of copper, but it can also consist of another good thermally conductive metal such as aluminum or stainless steel.
  • the Roller made of a good heat conductive material can also be surface coated and can be active be cooled.
  • the monofilament produced by the process is characterized by a round profile, a Boiling shrinkage ⁇ 10%, preferably ⁇ 6%, an elongation ⁇ 40% and a strength of> 35 cN / tex.
  • the number of monofilaments that can be produced from a spinneret is for the method according to the invention not critical and only depends on the width of the cooling roller and the arrangement of the winder.
  • the single figure shows a schematic representation of the method.
  • 1 represents a spinning block. Filaments are designated with 2, 2 'and 2 ". One with 800 - 1600 m / min peripheral speed rotatable roller 3 is followed by an air-bearing deflection roller 4. A heater 6 can be provided between the deflection roller 4 and the winder 7. The Device 5 for applying a spin finish can be arranged before or / and after the heater 6 be.
  • the filaments 2, 2 ', 2 In operation, the filaments 2, 2 ', 2 "directly from the nozzles of the spinning block 1 by means of the winder 7 drawn off at a speed of 4000 to 6000 m / min and to a number corresponding to the number of filaments Number of coils wound.
  • the filaments 2, 2 ', 2 run over part of the rotating Surface.
  • the roller 3 itself is not actively cooled. The heat supplied to the roller 3 by the filament 2 is released into the environment via the comparatively large roller surface.
  • the contact length of the filament 2 is set by means of the deflection roller 4. Before or after one possible heat treatment by the heater 6 is a spin preparation on the device 5 applied the thread.
  • the polymer used was a polyester with a VI of 74 (phenol / dichlorobenzene) at extruder temperatures of 275/280/285 ° C, a melting temperature of 287 ° C and a spinning block temperature of 295 ° C spun.
  • the spinneret characteristics were 2 x 6 / .33 / 4D and 1 x 5 / .33 / 4D.
  • the winding speed was 5000 m / min.
  • the circumferential speed of the roller was between 800 and 1600 m / min and the distance between spinneret and roller between 60 and 130 cm, depending on the titer varies.
  • a particular advantage of the method according to the invention is that in a one-stage Process at speeds over 4000 m / min fine monofilaments can be produced.
  • the roll parameters can be monofilaments at high speeds in one step with high Create strength, deep stretch and deep cook shrink.
