Definitions

  • the invention relates to a method for manufacturing a high-strength, high-shrinkage polyamide 66 filament yarn for industrial fabrics, in particular Airbag fabric, by multi-stage stretching of Polyamide-66-LOY using at least three heatable Stretching roller units or godet duos and immediate winding of the drawn yarn into one cylindrical package 'in particular to a Cheese and a polyamide 66 filament yarn.
  • thermoplastic Filaments are usually copse used, giving them one for further processing cheaper protective twine is issued.
  • the disadvantage of Cops is that the maximum Winding speeds in the range of just a few are a hundred meters per minute.
  • the cops rewinder is that the yarn capacity a stretch cop generally limited to approx. 4 kg of yarn is. Economic yarn production is after one such procedures are no longer guaranteed.
  • the immediate winding of shrinkable yarns too cylindrical coils would be desirable.
  • DE-A-34 37 943 describes a process for the production known from polyamide 66 filament yarn, where the yarn has a high strength, a high Elongation and low shrinkage and that, in contrast to yarns with one high shrinkage, can be wound on packages without problems.
  • the suitable device consists of several heated stretching roller units. To improve the Drawability of the yarn also becomes sources of heat in the form of contact heaters between the stretching rollers intended. It is known that when Melt spinning process, at a winding speed of 4500 m / min and above, the winding tension so is increased that a paper spool of the winding machine is not more can be removed. The problem with this Procedure solved by relaxing by about 10%. For the No winding of the drawn yarn is given made.
  • the well-known yarns are at speeds of a maximum of 20 m / min.
  • Aim of the known Process is the production of so-called dimensionally stable filament yarns for tire cord fabrics, with high strength, high elongation and a low Shrinkage, if possible below 5%.
  • these yarns they are Stretching conditions and especially the winding conditions optimized on packages.
  • the object of the invention is a high-strength, high shrinking polyamide 66 filament yarn to manufacture, which then follows the Can stretch directly on packages.
  • Another job is to do both Production speed as well as the unit weight the thread carrier and thus the economy of the To increase the stretching and winding process. Facilities for Allow generation of cylindrical cheese Production speeds of several thousand meters per minute.
  • the object is achieved in that at a relaxation ratio of 4 to 10%, the Temperature of the last stretching roller unit before Winding between 70 ° C and 160 ° C, especially 80 ° C and 150 ° C, preferably to 90 ° C - 140 ° C and the Winding tension to less than 0.2 cN / tex, especially to less than 0.15 cN / tex, preferably less than 0.13 cN / tex can be set.
  • the thread tension in the winding area essentially becomes by the relaxation ratio, i.e. by the Ratio of the speeds of the last Stretch godet and the winding device determined. It is expedient, the relaxation ratio between 4 and 10% to choose.
  • the polyamide 66 filament yarn shows a relative Viscosity (RV) of> 40, measured in 90% Formic acid according to ASTM 0789-81, a strength of at least 60 cN / tex, an elongation of 10-25% and one Thermal shrinkage of 7-11% at 160 ° C and is one Cross-wound bobbin with at least 6 kg thread mass. It is surprisingly successful, such a shrinking Polyamide yarn to 6 kg spools instead of uneconomical copse with a maximum of 4 kg Capacity.
  • RV Viscosity
  • the polyamide 66 filament yarn according to the invention is for industrial fabrics, in particular for airbag fabrics suitable, which besides high strength also should have a particularly high thermal shrinkage.
  • reference numeral 1 is an undrawn one Designated polyamide-66-LOY filament.
  • the filament is from a delivery roller, not shown, to a first one heated stretching roller unit 2 fed. Between the Delivery roller and the first stretch roller unit 2 is slightly stretched undrawn filament 1 by approx. 3%, to give the filament 1 a minimal tension.
  • the Thread tension must be selected so that a sufficient adhesion between filament 1 and guaranteed the surface of the stretching roller assembly 2 is the one that occurs in the first drawing stage Stretching force to provide the required resistance.
  • a third stretching roller unit 4 with a The surface temperature is from 70 ° C to 150 ° C heated stretching roller unit 3 and causes another second stretching.
  • the drawn filament 5 is opened a cheese 6 wound.
  • Thread tension becomes the filament at a speed spooled, which is set about 6% lower than the speed of the aggregate 4.
  • the winding tension is thereby set to, for example, 0.13 cN / dtex.
  • All drawing roller units are from the filament 1 wrapped several times around, on the one hand the necessary Ensure frictional connection for stretching and around on the other hand, an adequate heat exchange between the heated roll surfaces and the filament 1 guarantee.
  • Fig. 2 differs from Fig. 1 by a Additional stretching roller unit 7.
  • the stretching roller unit 7 for example heated to a temperature of 180 ° C.
  • the second stretch between the Stretching roller units 3 and 7 carried out during the Temperature of the stretching roller unit 4. compared to Arrangement in Fig. 1 is not changed.
  • the speed of the stretching roller assembly 4 is there at least as high as that of the Stretching roller unit 7.
  • the device according to FIG. 1 is exemplary and not only suitable for performing the procedure.
  • a device suitable for the method can instead of the stretching roller units with separating rollers also consist of godet duos. Furthermore, between the units further elements for thermal Treatment of the yarn such as block or radiant heaters, Hot air or steam nozzles can be arranged. Further is it is expedient to use a Whirl air nozzle or the like to thereby the Improve processability.
  • This device is also not for just one Filament thread suitable for finer yarns, for example with a titer of 470 dtex or less, can also use two or more filament threads at the same time stretched and on a correspondingly multi-ended Be wound up.
  • the operating speed of this device is in the Range between 300 and 3,000 m / min. It is therefore much more productive than conventional draw twisting machines, who put the thread on cops. Can also Cross-wound bobbins with a thread mass of more than 10 kg getting produced. Opposite the cops makeup with a maximum of 4 kg is much less Manipulations required.
  • the high working speed does not limit the usability on the stretching of already wound LOY filament yarns on. In principle, it is also for the Use in an integrated spin-stretch process suitable.
