Definitions

  • the present invention relates to a device for melt spinning multifilament threads from thread-forming polymers at winding speeds of at least 2,000 m / min with a spinneret, a cooling device for solidifying the threads, an assembly element for the filaments and a winding, at least between the nozzle and the former
  • An essentially vertical spinning line is provided in the merging member, the cooling device being a porous tube which is open in the spinning direction and is arranged concentrically to the spinning line, and wherein the porous tube is not preceded or connected by any further devices which supply or discharge a cooling medium according to application, file number P 41 29 521.8
  • the invention also relates to the use of this device for the production of polyester filament yarns.
  • the object of the present invention is to provide the device described in the application, file number P 41 29 521.8 for special uses, in particular for winding speeds of 2000 to 6000 m / min.
  • a further, non-porous tube can be connected in a particularly simple manner to the porous tube in that a lower section of the porous tube is covered.
  • the device according to the invention is therefore advantageously characterized in that the further, non-porous tube is formed by a cover arranged on the porous tube.
  • the further, non-porous tube can be followed by further sections of porous and non-porous tubes.
  • the production of multifilament threads is particularly successful if free inflow of a cooling medium below the porous tube is completely prevented. It has proven particularly useful here if the porous tube has a length of 10 to 800 mm. A length of 200 to 800 mm has proven to be particularly advantageous for the further, non-porous tube connected downstream of the porous tube.
  • polyethylene terephthalate, polyamide, polyamide 6, polyamide 6,6, their copolymers and mixtures of these polishes are very suitable for spinning with the device according to the invention.
  • the length of the tube is also very easy to adapt the length of the tube to an optimal course of the spinning. To do this, it is only necessary to provide a set of porous tubes of different lengths, for example in the range from 10 to 800 mm, the lengths of the individual tubes differing by about 100 mm, for example.
  • the porous tube can also be made telescopic.
  • a porous tube with a length that is in the upper range of the specified lengths should be used.
  • porous tube together with the downstream non-porous tube have a constant cross section in the longitudinal direction thereof, which makes it particularly easy to spin on the device, because the filaments pass through the tube zone in free fall and are caught underneath the tube can be.
  • other tube shapes are also possible, for example frusto-conical tubes.
  • the cooling air required to solidify the threads is sucked in by the threads themselves through the porous tube due to the speed of the threads. Conditioning of the cooling air is not necessary.
  • the normal climate in the range of device according to the invention which is why the operating personnel can work in a comfortable climate on the device according to the invention.
  • the device according to the invention requires less space than the known devices because no channels for supplying conditioned air are required. There is less waste when piecing.
  • the device is also characterized by a particularly low energy requirement, since no conditioning of the cooling air and no further devices influencing the temperature of the thread are required before winding up.
  • the porous tube and the downstream non-porous tube are cylindrical, the cross section of the cylinder being able to have practically all common geometric shapes such as, for example, a circle, ellipse, octagon or hexagon.
  • the inner cross section of the porous tube and the downstream non-porous tube has at least approximately the same geometrical figure as the outer contour of the filament bundle. This results in a particularly uniform solidification of the individual filaments.
  • porous tube When selecting the material for the porous tube, it is only necessary to ensure that the porous tube can be attached directly to the spinneret and therefore not yet softened at the temperatures prevailing in the spinneret. Metals, in particular steel, are particularly suitable for this.
  • the porosity of the tubes can be ensured by perforated tubes, but also by sintered metals.
  • all the porous tubes are suitable, the porosity of which, at a flow rate of air at 1 m / s, causes a pressure loss of approximately 3 to 150 Pa, a pressure loss in the range of 10 Pa having been found to be favorable.
  • the porous tube is formed from a metal sieve, a metal sieve with 60 mesh being very suitable.
  • a further tube made of perforated plate can be arranged within the metal sieve tube.
  • the porous tube can be connected directly to the spinneret. Between the spinneret and the porous tube, however, an up to 300 mm long device which hinders the cooling of the filaments and to which the porous tube connects can be interposed.
  • the filament cooling can be impeded, for example, in that the cooling-obstructing device consists of a hot air stream enveloping the filaments. This results in a particularly uniform, delayed cooling of the filaments.
  • the hot air jacket has a temperature which corresponds approximately to the temperature of the spinneret.
  • the hot air jacket can be achieved particularly inexpensively if the spinneret is a multiple spinneret, in which the pressing out of the melt is provided in the middle, and in which one or more openings are provided concentrically around the center, through which a hot air stream exits the filaments covered. It is particularly advantageous here if the opening arranged concentrically around the center is an annular gap.
  • the use of such spinnerets for delayed cooling of the filaments is known per se from DE-OS 39 41 824 and from EP-A-0 455 897.
  • a hindrance to filament cooling can also be achieved in a particularly simple manner in that the device which hinders the cooling of the filaments is a heated, in particular an unheated, tube.
  • the device that hinders the cooling of the filaments is particularly simple if a section of the portion of the porous tube facing the spinneret that is up to 300 mm long is covered.
  • the covered section is preferably arranged directly below the spinneret.
  • the impediment to filament cooling results in a delayed cooling of the filaments, which promotes an undisturbed spinning process, particularly with low individual titers.
  • the device according to the invention has proven particularly useful if the merging member is arranged at a distance of 400 to 2,000 mm from the spinneret, but at least about 100 mm below the non-porous tube after the porous tube.
  • the merging member can be a thread guide. Particularly useful it is, however, if the merging member is a preparation application device known per se.
  • the device according to the invention particularly large distances between the spinneret and the take-up of, for example, up to 9000 mm can also be achieved.
  • the device according to the invention has proven particularly useful when the winding is arranged approximately 2,000 to 4,000 mm below the spinneret.
  • a device for swirling the filaments is arranged before winding.
  • a further reduction in spinning disturbances is achieved in that the spinneret is preceded by a melt line for feeding the polymer melt from an extruder to the spinneret, in which line at least one static mixer is arranged. In this way the uniformity properties of the spun filament yarns are also favorably influenced.
  • the static mixers are arranged at one or more points in the melt line between the extruder and the spinneret.
  • the polyester filament yarns When using the device according to the invention for the production of polyester filament yarns, the polyester filament yarns being wound at speeds of up to 10,000 m / min, the yarns obtained in this way have low cooking and hot air shrinkage values and can be dyed particularly uniformly and deeply.
  • the use of the device has also proven to be particularly favorable for the production of filament yarns from polyethylene terephthalate, polyamide, polyamide 6, polyamide 6,6, their copolymers or from mixtures of these polymers.
  • the device is also excellently suited for use in the production of POY or FOY filament yarns, the filament yarns being wound at speeds of 2,000 to 8,000 m / min, after which the filaments of the filament yarns have a single titer of 0.1 to 5 dtex exhibit.
  • microfibers whose individual titers are in the range from about 0.1 to 1.5 dtex can thus also be produced particularly cheaply, be produced, but it is recommended to choose a lower winding speed and machine height, the lower the individual titer of the filaments of the filament yarns should be.
  • the device according to the invention is particularly suitable for the production of POY yarns. It is therefore also preferred to use the device according to the invention for the production of polyester rovings, the polyester rovings being wound up at speeds of 2,000 to 6,000 m / min.
