Definitions

  • the invention relates to a method and an apparatus for producing flock yarn, in which, on a running synthetic carrier thread, first a thin layer of thermoplastic adhesive and then all around flock fibers are applied electrostatically, the flocked yarn is then dried in a tensioned state and finally wound up.
  • an electrostatic flocking device to be passed through a sheet of carrier thread to be flocked, an upper and lower high-voltage electrode and a flock fiber conveyor belt, and a drying cabinet connected downstream of the latter and a winding creel.
  • the method and device of the above type are known, for example, from DE- PS 16 35 235.
  • the electrostatic flocking of yarns requires a relatively high thread tension of the carrier threads both during the Flocking process as well as in the drying cabinet. These high yarn tensions have anyhow with synthetic T rägerfäden the result that their elastic expansion behavior characterized back essential and they lose about half of their elongation at break. At the same time, their shrinking capacity increases with such flocked synthetic carrier threads. The result is a relatively inelastic flock yarn with low elongation at break and high shrinkage behavior. Therefore, the electrostatic flock yarns made of synthetic carrier thread material and the woven or knitted fabrics made therefrom are still quite sensitive to the effects of heat, especially in the de-energized state. There is an uneven penetration of the tissue in the direction of the flock threads. The textile fabric then becomes wavy and cannot be sold and processed as quality goods.
  • the invention has for its object to produce an electrostatically flocked yarn which, although it has synthetic carrier threads, does not have the aforementioned deficiencies, rather has a much better elongation behavior and is significantly less sensitive to the effects of heat, especially in the de-energized state.
  • this object is essentially achieved in that the freshly flocked yarn is subjected to a low-tension or no-tension thermal shrinkage treatment after it has dried and before it is wound up.
  • the freshly flocked yarn has the desired elasticity, high elongation at break and only low residual shrinkage after its comparatively stressful drying by subsequent stress-free or low-stress heat treatment.
  • These advantageous properties are fixed by cooling following the hot air treatment or shrinking. It arises in this way stable, easy to process flock yarn.
  • the woven and knitted fabrics made from it are normally stable against heat and well elastic.
  • it is essential that the integration of the shrinking treatment in the normal flock yarn manufacturing process does not involve any significant additional manufacturing effort.
  • a heatable shrink cabinet with support rollers and a cooling zone connected downstream of the latter for the flock yarn group is provided between the drying cabinet and the winding creel.
  • conveyor roller arrangements are provided for the flock yarn group, of which at least the conveyor rollers downstream of the shrink chamber are provided with a controllable drive, so that the flock yarn group can be kept in a sufficiently low-tension or low-tension state when passing through the shrink chamber. Both horizontal and vertical running of the flock yarn group is possible in the shrink yarn cabinet.
  • an apparatus for producing electrostatically flocked yarn according to the invention is shown, all in a schematic manner.
  • This device essentially consists of the flock fiber feed device 1, which can be driven all round F lock fiber conveyor belt 2; the adhesive application device 4 filled with a thermoplastic adhesive solution 3, the electrostatic flocking device 5 connected in series, the drying cabinet 6, the shrink cabinet 7 and the winding creel 8.
  • the electrostatic consisting of synthetic thread material, for example of polyamide, polyester or polyacrylic fibers flocking carrier thread sheet 9 comes from a spool drain gate, not shown, passes the adhesive application device 4, where it is loaded with the adhesive 3 in a thin layer, and then runs through the electrostatic flocking device 5.
  • the electrically grounded T are rägerfäden 9 coated from the flock fibers 12 all around, the fly under the influence of the electrostatic field in radially aligned form on the carrier threads and stick there fixed with its one end in the adhesive layer.
  • the flock yarn group 9 passes the conveyor roller trio 12 in order to then pass through the shrinking cabinet 7.
  • This is provided with a plurality of support rollers 13, which are arranged horizontally next to one another at sufficient intervals and which also support the above Carefully wear flocking yarn 9 'which moves away under slight contact pressure and let it shrink unhindered under the influence of the heat coming from the heating fan 14. So that this shrinkage can be tensionless or at least as tension-free as possible, a conveyor roller duo 15 with a controllable drive is provided behind the shrink cabinet 7, which, in coordination with the conveyor roller trio 12, allows the flock yarn tension to be kept as low as possible. The yarn is guided safely by appropriate surface design of the rollers 15.
  • the treatment temperatures in the shrink chamber are between 140 ° C and 200 ° C.
  • the yarn tension in the shrink chamber is less than 50 p, preferably less than 20 p.
  • the residence time of the flock yarn in the shrinking chamber should be at least 0.5 minutes, but preferably several minutes.
