Definitions

  • the invention relates to the production of yarns by melt spinning of polyethylene terephthalate, hereinafter abbreviated PETP, solid PETP being melted in a single operation, pressed through nozzle openings, solidified and drawn into a yarn.
  • PETP polyethylene terephthalate
  • Such a method is known and is used, for example, for the production of yarns for technical applications, for example for the reinforcement of rubber articles such as car tires.
  • Yarns used in car tires should preferably have a high modulus (HM) and a low shrinkage (LS).
  • HM high modulus
  • LS low shrinkage
  • the yarns produced in accordance with the invention are referred to below as HMLS yarns.
  • the HMLS yarns produced according to the invention can be processed in a known way to reinforcing cords for tires and this cord can, according to a likewise known method, be provided with an adhesive, a so-called "dip", whereby a "dipped cord” is obtained.
  • the dipped cord which is obtained from the HMLS yarns produced according to the invention has a low hot air shrinkage (HAS / hot air shrinkage) in the range from 3.5 to 1.5%.
  • HMLS yarns with the properties mentioned can be produced in a known manner by spinning PETP at a speed of approximately 4000 m / min to form a roving with a high degree of orientation, which then has to be stretched approximately twice.
  • a lower spinning speed in the range between 1500 and 4000 m / min would have to be selected in order to be able to stretch and wind up the roving thus obtained so that a speed of 6000 m / min is not exceeded.
  • the roving is too low pre-orientation, so that the desired HMLS properties cannot be achieved in a one-step process.
  • the object of the present invention is therefore to provide a method of the type mentioned at the outset with which HMLS yarns can be produced in a one-step process.
  • BKI in the PETP before spinning is known per se from US Pat. No. 3,692,745. According to the method described there, BKI is added to the PETP in order to reduce the concentration of the carboxyl groups of the PETP, with the aim of greater chemical stability. None is mentioned in this patent of the spinning conditions mentioned under c and d, nor is there any indication that an HMLS yarn can be produced using a combination of steps a to d. According to the US patent mentioned, BKI can be added to the polymer, for example, by adding powdered BKI to PETP grains (so-called breading). BKI can also be added to the previously melted polymer.
  • the preferred BKI is N, N ⁇ -bis (diphenylvinylidene) p-phenylenediamine, which is easy to prepare and gives good results.
  • Other types of BKI can also be used, for example N, N ⁇ -bis (diphenylvinylidene) -4,4 ⁇ -diphenylmethane diamine and N, N ⁇ -bis (diphenylvinylidene) hexamethylene diamine.
  • the speed at which the polymer is drawn off from the spinnerets is between 1500 and 4000 m / min depending on the relative viscosity and the desired properties of the end product. At low take-off speeds, a somewhat higher draw ratio (for example around 4.0) is usually required in the last operation than with a higher take-off speed.
  • the yarns produced according to the invention have the above-mentioned HMLS properties. They also have better thermal and chemical stability than yarns with HMLS properties that were spun without BKI.
  • the high spinning speed generally required with HMLS yarns results in an open structure that is sensitive to chemical attack and high temperatures. This sensitivity decreases with the addition of BKI.
  • the parameters used such as titer (linear density), modulus, strength, 5% LASE (Load At Specified Elongation), elongation at break and hot air shrinkage at 180 ° C are determined in accordance with ASTM D885-M-1979. Deviating from these regulations, the hot air shrinkage, HAS, is measured at 180 ° C and with a preload of 1 cN / tex.
  • the starting point is PETP grains which have the relative viscosity given in the table below. These grains are dusted with the specified amount of N, N ⁇ -bis (diphenylvinylidene) p-phenylenediamine. Then they are melted at 290 ° C and extruded through a heated spinneret plate with 140 holes with a diameter of 400 ⁇ m. After leaving the spinning plate, the threads are drawn off at a speed v 1, as indicated in the table. They are cooled with air at room temperature. The threads are passed over godets and then stretched by winding at a speed v2, as indicated in the table. The threads have the properties mentioned in the table under "Yarn".
  • a tire cord with dtex 1100 (Z 472) ⁇ 2 (S 472) is produced in a known manner with the yarn obtained.
  • the untreated cord is then dipped in two dip baths to improve the adhesion with the elastomeric material.
  • the properties of the dipped cord are also shown in the table.
  • the dipping of the cord according to the invention in two baths takes place in a way known per se.
  • the cord is passed through a first bath to apply a pre-dip and then through a second bath to apply the main dip. Between the first and second baths, the cord is dried for 60 seconds at 240 ° C and a tension of 10N. After applying the main dip, i.e. after leaving the second bath, the cord is dried again for 120 seconds at 220 ° C. and a tension of 4.5 N.
  • compositions of the immersion baths are the same as in the example of EP-A-201 114.
