Definitions

  • the present invention is directed to a process for producing bulked continuous filament PTT yarns wherein the yarns can be combined with other types of yarns in a two stage process, and wherein carpets made from such yarns have unexpectedly improved wear resistance.
  • Fig. 2 schematically depicts the steps of texturing the drawn yarn.
  • Spin finish is applied using a suitable device, such as a kiss roll or a metered finish applicator.
  • the primary purpose of the spin finish is to promote bundle cohesion and reduce surface friction so as to assist in any further yarn processing steps such as texturing and yarn twisting.
  • Functional additives may be incorporated into the spin finish, such as stain resistance additives and anti-soiling additives including fluorochemicals.
  • the yarn denier is fed around a first unheated roll to control yarn denier.
  • the yarn is then fed to a second roll which is heated to a temperature of between 45 ° C and 150 ° C.
  • the actual roll temperature used is dependent on the yarn contact time on the roll.
  • the contact time/roll temperature used should be adjusted so that crystallization of the PTT polymer is not significantly induced.
  • the yarn is tensioned, but not so that the yarn is permanently stretched.
  • the second roll can be rotated at a 2% greater speed than the first roll.
  • the yarn is then fed to a third roll that is heated to give a yarn temperature above the glass transition temperature and preferably between 100°C and 200°C.
  • the measured glass transition temperature of the yarn will depend on the method used to determine it.
  • the method used to determine the glass transition temperature in this invention is by use of differential scanning calorimetry at a heating rate of 10 ° C/minute.
  • the glass transition temperature is the midpoint of the inflexion relating to the glass transition of the differential scanning calorimetry curve.
  • the actual roll temperature used shall again depend on the yarn contact time on the roll.
  • the speed of the third roll will be set faster than that of the second roll to give a yarn draw ratio between the second and third rolls of at least 1.25, but lower than that required to break the yarn under the conditions used.
  • the drawn yarn is wound up using a suitable winding device.
  • Intrinsic Viscosity 0.2990-0.3010 g of the sample is dissolved in 25 cm' of 99+% dichlororacetic acid obtained from Aldrich Chemical Co., Inc. The viscosity of the solution is measured using a Cannon-Ubbelohde type 100 viscometer at 34.8" - 35.2°C.
  • Yarn was spun per Example 2 except the denier was also adjusted to 590/34Y by changing the spin pump speed.
  • the drawn yarn tenacity was 2.7 g/denier with a % elongation of 39%. No degradation of properties occurred in the yarn after conditioning the yarn for 24 ours at 70°F and 50% RH. 4 ends of this yarn were co-textured together via a mechanical crimping process without further drawing to produce a 2-dimensional rectilinear crimp with a denier of 2360. No yarn or filament breakages occurred during the yarn crimping process.
  • the textured yarn tenacity was 1.5 g/denier and % elongation was 46%.
  • Example 7 Eight ends of yarn produced in Example 7 were co-textured together using a mechanical crimping unit without further drawing similar to that used in Example 5 with the yarn heated to the same temperatures in the manner described in Example 5. No yarn or filament breakage occurred during the yarn crimping process.
  • the textured yarn product had a denier of 2645 with a tenacity of 2.0 g/denier and a % elongation at break of 44%.
  • Carpet was made from the yarn in a manner similar to Example 12. The carpet was subjected to the wear test described above. The grade of the worn carpet was 4.
  • This example demonstrates the effect of two-stage drawing on yarn performance.

Abstract

Dans un procédé de production d'un fil en poly(triméthylène-téréphthalate), à partir d'un cristal de PTT mélangé avec un additif dans un support préalablement à sa fusion, malaxé et extrudé en fils continus à travers une presse à filer (2) puis enduit, les fils continus enduits sont passés entre un cylindre alimentaire non chauffé (4) et un galet tendeur de manchon afin de les tendre sans causer un allongement permanent. Les fils continus enduits sont ensuite acheminés du galet tendeur de manchon à un rouleau entraîneur chauffé (7) aux fins de les étirer en une seule passe selon un taux d'étirage compris entre 1,25 et 4,0 et de les chauffer à une température située entre leur température de transition vitreuse et leur température de cristallisation.
