Definitions

  • the present invention relates to a method of spinning a multifilament yarn made of a thermoplastic material, comprising the steps of extruding the molten material through a plurality of nozzle holes of a spinneret into a filament bundle with many filaments and wound up as a thread after solidification, and in which the filament bundle is cooled below the spinneret. Furthermore, the present invention relates to polyester filament yarns and cords containing such polyester filament yarns.
  • a two-stage cooling method for spinning a multifilament thread from a thermoplastic material is known in JP 11061550 disclosed.
  • the filaments are blown on one side or in a ring and in a second stage
  • compressed air is injected so that a downward flow occurs parallel to the filaments. This is intended to give the filaments as uniform physical properties as possible.
  • thermoplastic polymers The cooling behavior of the thermoplastic polymers is quite complicated and depends on a number of parameters. In particular, it comes during the formation of differences in birefringence over the filament cross-section, because the filament skin cools faster than the inside, the core, the filaments. In addition, differences in crystallization between filaments also occur in this way. Cooling thus determines to a high degree the crystallization of the polymers in the filament, which is noticeable during the later use of the filaments, for example during drawing. For a number of applications, it is desirable to achieve a high degree of cooling as soon as possible after extrusion to promote rapid crystallization.
  • the object is achieved in that the method as described in the preamble of claim 1, characterized in that the cooling is carried out in two stages, wherein in a first cooling zone, the filament bundle is so impinged by means of a gaseous cooling medium that the gaseous Cooling medium flows through the filament bundle, by the filament bundle on the opposite side of the flow almost completely leaves again, and in a second cooling zone below the first cooling zone, the filament bundle is substantially further cooled by Diansaugung located in the vicinity of the filament bundle gaseous cooling medium.
  • the present invention is a two-stage cooling.
  • the filament bundle is flowed through by means of the gaseous cooling medium. It is especially crucial that the cooling medium, the filament bundle practically completely on the opposite side of the inflow side leaves again.
  • the cooling medium should therefore not be carried along by the filament bundle in this stage of cooling.
  • the gaseous cooling medium flows through the filament bundle transversely to the direction of movement of the filament bundles, that is to say a so-called transverse blowing is set. This blowing can be effectively designed by the gaseous cooling medium is sucked by flowing through the filament bundle by means of a suction device.
  • the embodiment can take place in such a way that the filament bundle is passed between a blowing device and a suction device.
  • Another possibility is to divide the filament stream and, for example, to initiate an injection in the middle between two filament streams, such as through a perforated tube running parallel for a certain distance and between the filament streams. It is then possible to blow the gaseous cooling medium from the middle of the filament bundles out through the filament bundles to the outside. Again, make sure that the cooling medium leaves the bundles almost completely again.
  • the reverse blowing and Absaug gag be installed would be conceivable by the running in the middle of the filament streams pipe serves as a suction and the blowing is then carried out from outside to inside.
  • the flow velocity of the gaseous cooling medium is between 0.1 and 1 m / s. At these rates, there is a uniform cooling largely without turbulence and formation of skin / core differences in the crystallization.
  • the first cooling zone has a length between 0.2 and 1.2 m. An inflow over this length and under the conditions described above gives the desired degree of cooling in the first zone or stage.
  • the second stage of the cooling is carried out by means of the so-called self-suction yarn cooling.
  • the filament bundle tears the gaseous cooling medium in its environment, for example ambient air, with it and is thereby cooled further.
  • there is a flow of the gaseous cooling medium which runs substantially parallel to the direction of the filament bundle. It is important that the gaseous cooling medium approaches the filament bundle at least from two sides.
  • the Diansaugody can be formed by two perforated and parallel to the filament bundle plates, so-called double-sided plates.
  • the length is at least 10 cm and can be up to several meters at the top. Quite usual are lengths for this Diansaugungsumble from 30 cm to 150 cm.
  • the second cooling step be accomplished by passing the filaments between perforated materials, e.g. perforated plates, is carried out so that the gaseous cooling medium can meet on the self-priming of two sides of the filaments.
  • this element which is familiar to the person skilled in the art, is between 10 and 40 cm long.
  • a bundling step may advantageously be carried out in a manner known per se, e.g. by so-called airmover or airknives. Furthermore, this bundling step can also take place within the second cooling zone.
  • the method according to the invention after the cooling zones and before winding still have a stretching of the filaments in a conventional manner.
  • stretching is to be understood here as meaning all customary methods familiar to the person skilled in the art in order to distort the filaments. This can be done for example by godets, individually or in duos, or the like. It should be expressly mentioned that drawing refers both to draw ratios greater than 1 and to ratios which are less than 1. The latter ratios are familiar to those skilled in the art of relaxation. Stretch ratios greater than and less than 1 occur quite side by side within a process.
  • the total draw ratio is usually calculated from the ratio of the draw speeds or, if relaxation is still taking place, the take-up speed at the end of the process and the filament spin speed, i. the speed at which the filament bundles pass through the cooling zones.
  • a typical constellation is, for example, a spinning speed of 2760 m / min, draw at 6000 m / min, additional relaxation following the draw of 0.5%, i. a winding speed of 5970 m / min. This results in a total draw ratio of 2.16.
  • speeds of at least 2000 m / min are preferred for winding.
  • the process is within the scope of the technically feasible There are no limits on speed.
  • about 6000 m / min is preferred for the upper speed range during winding.
  • the drafting devices upstream and behind the cooling zones may still be a chute. This element is known per se.
  • the gaseous cooling medium used is preferably air or an inert gas, such as nitrogen or argon.
  • the inventive method is in principle not limited to certain types of polymers and can be applied to all filament extrudable polymer types.
  • thermoplastic material consists essentially of polyethylene terephthalate.
  • the process according to the invention allows the production of filaments which are particularly well suited for technical applications, in particular suitable for use in tire cord. Furthermore, the method is also well suited for the production of technical yarns.
  • the settings necessary for the spinning of technical yarns, in particular the choice of the nozzle and the length of the heating tube, are known to the person skilled in the art.
  • the invention is therefore also directed to filament yarns, in particular polyester filament yarns obtainable by the process described above.
  • the present invention is directed to such polyester filament yarns having a book strength T in mN / tex and an elongation at break E in%, in which the product of the breaking strength T and the third root of elongation at break E (T * E 1/3 ) is at least 1600 mN% 1/3 / tex. Preferably, this product is between 1600 and 1800 mN% 1/3 / tex.
  • the invention is directed to polyester filament yarns in which the sum of their% elongation after application of a specific force EAST ("elongation at specific tension") of 410 mN / tex and their hot air shrinkage at 180 ° C (HAS) in %, ie the sum of EAST + HAS, less than 11%, preferably less than 10.5%.
  • EAST elongation at specific tension
  • the EAST is measured according to ASTM 885 and the HAS is also determined according to ASTM 885, with the proviso that the measurement is carried out at 180 ° C, at 5 mN / tex and for 2 minutes.
  • the present invention is directed to tire cords containing polyester filament yarns, wherein the cord has a retention percentage Rt in%, which is characterized by the quality factor Q f , which is the product of T * E 1/3 of the polyester filament yarns and Rt of the cord represents greater than 1350 mN% 4/3 / tex.
  • the retention capacity is to be understood as the quotient of the breaking strength of the cord after dipping and the breaking strength of the threads.
  • the quality factor is particularly preferably greater than 1375 mN% 4/3 / tex and is advantageously up to 1800 mN% 43 / tex.
  • Polyethylene terephthalate granules having a relative viscosity of 2.04 (measured on a solution of 1 g of polymer in 125 g of a mixture of 2,4,6-trichlorophenol and phenol (TCF / F, 7:10 m / m) at 25 ° C in an Ubbelohde (DIN 51562) viscometer) was spun and cooled under the conditions listed in Tab. 1. The stretching speed was 6000 m / min. An additional relaxation of 0.5% was set, winding speed: 5970 m / min. ⁇ B> Table.
