Definitions

  • the invention describes a method and an apparatus for the production of textured filament tapes for artificial grass, wherein these tapes are stretched between two heating godets and then textured and the textured filament tapes are peeled off over a cooling godet and then wound up.
  • a cooling godet or roll for treating synthetic filament or web shaped stock is also made DE 28 44 207 known.
  • a device for continuous curling of thermoplastic threads in which the crimping (texturing) is carried out with a stuffer box attached tangentially to a rotary cylinder and the rotary cylinder is used for cooling.
  • openings are provided after the stuffer box on the outside of the rotary cylinder through which cooling air is supplied via the cylinder and a cover plate.
  • the object of the present invention is to provide a method and an apparatus for producing extremely crimped polymer tapes, which are suitable for use in artificial turf fields, for example for football, hockey, tennis or golf courses and are characterized by a high strength great volume and high elasticity.
  • a polymeric material is processed in the form of tapes 10 0.5 to 1.5 mm wide and having a linear density of 250 to 1200 dtex.
  • the polymeric materials for example, PA (polyamide), PP (polypropylene) or LLDPE (linear low density polyethylene) are used.
  • the tapes 10 are fed from a gate or processed directly from the extruder coming.
  • the tapes 10 are subjected to a H thoroughly Kunststofftextur istsvon in a stuffer box 13, wherein the tapes 10 are pressed into a chamber and compressed at the Faserpfropfen formed there. This leads to a mutual buckling of the filaments.
  • the stuffer box has a side inlet for a hot air texturing nozzle 21 and an air outlet area 23.
  • the resulting structure is still heat set in the chamber with hot air from the texturing nozzle 21. It forms a three-dimensional, sawtooth curling structure.
  • Commercially available compression chambers can be used in the process.
  • thedegalette 14 has a suction 15.
  • a radial guide groove 25 is arranged with small openings 26, is sucked through the air from outside to inside and ensure a sufficiently large air flow for cooling ,
  • the radius of the guide groove 25 is adapted to the textured material.
  • the filament ribbons 10 generally lie on a circular arc of less than 360 °, e.g. one of about 180 °, on thedegalette 14 at.
  • a standing cover 19 is installed, which shields from the inside the part of the guide groove 25, on which no filament ribbon lie. As a result, an unnecessary consumption of suction air and an unnecessary reduction of the negative pressure in the cooling godet 14 is avoided.
  • the textured tapes 10 in the desired segment of e.g. held about 180 ° on the circumference of the cooling godet 14 in the guide groove 25 and cooled. Due to the cooling, the glass point falls quickly, so that the texture of the fibers is fixed by the onset of crystallization.
  • the speed difference between the extrusion and the winding is 5-35%, the extrusion speed being higher by a factor of 1.05 to 1.35 than the winding speed. This allows production speeds of 100 - 500 m / min. to reach.
  • the fibers thus obtained can now be bundled as fiber groups and anchored on dimensionally stable carrier fabric, whereby an artificial turf field is obtained with high elasticity, an optimal Wiederaufstellhunt and high abrasion resistance.
  • the cooled tapes 10 are picked up by the take-off godet 16 and fed to the winding machine, the winding tension being 300 g.
  • the difference in speed between extrusion and winding is 25%, thus compensating for shrinkback. It is a production speed of 400 m / min. reached.
