Definitions

  • elastane threads are included for the first time a titer of at least 2,500 dtex after the wet spinning process become.
  • coarse titers which are in a ribbon form with bandwidths of typically approx. 2 to 10mm and in the typical application areas going from natural rubber threads are very interesting.
  • applications are, for example, elastic sub-bands for upholstery fabrics, backing material for Underwear, leg ends for laundry and bathing articles, as well as special hygiene articles in health care.
  • coils with different tube widths are e.g. from approx. 58 to 160 mm inserted. Furthermore, bobbins with different weights of elastane threads generated.
  • Sleeve width and spool weights naturally depend on the titers of the spun elastane threads. To the longest possible thread lengths and therefore little To achieve interruptions in the processing of the elastane threads For example, elastane threads of 1,280 dtex on wide sleeves 160 mm in length made with weights up to approx. 1.5 kg. This corresponds to a thread length of approx. 11.7 km.
  • the coil run time is only 15 minutes. This means one high personnel requirements when changing bobbins, which in turn leads to economic disadvantages leads to the use of coils.
  • the object of the present invention was to overcome these serious disadvantages and a shelf for coarse titer elastane threads of more than 2,500 dtex sufficiently long run length of at least 10 km, preferably 15 km and in particular of more than 20 km.
  • the invention relates to a method for depositing elastane threads with a titer of at least 2,500 dtex in containers with a thread length of at least 10 km, preferably at least 15 km, particularly preferably at least 20 km using a laying device, the threads meandering are deposited in layers, characterized in that the threads at a speed of at least 8%, preferably at least 10% above the production speed the threads are paneled in the container.
  • the meandering i.e. the space in the container runs back and forth Container especially used.
  • a feed roller is preferably used to produce the paneling in the container, which has a Teflon coating (PTFE) or a paper coating.
  • PTFE Teflon coating
  • a pivotable, funnel-shaped tray is particularly preferred for storage used, the width of which is perpendicular to the direction of rotation at its lower end seen is not more than 100 mm.
  • the threads entering the weaver are preferably in the direction of travel Blown threads with compressed air.
  • the deposited threads are preferably additionally compacted in the container, in particular using multiple punches to achieve a higher packing density guarantee.
  • the container is particularly preferred during the filing of the threads across
  • the thread running direction and perpendicular to the swivel direction of the destacker changes make optimal use of the space in the container.
  • Guide rubberized rollers or rollers in the feed drive of the laying machine especially increases the formation of wraps due to the tendency of the elastane threads to stick.
  • the speed must between the delivery of the thread, the so-called production speed, and the speed of the preferably hard paper-coated feed rollers is good be coordinated.
  • the feed rollers advance by 10%.
  • the speeds of the feed rollers or rolls are higher at higher speeds advantageously 20 to 50% more than the production speed of the Elastane.
  • Thread jams in the elastane threads occur primarily at the thread transition from the feed drive to the changeable special hopper feeder.
  • the supply of compressed air has The direction of thread running directly at the hopper entrance has proven particularly effective. Depending on Production speed and throughput often benefit from the compressed air supply to be distributed over 2 places at the funnel entrance. Generally enough small amounts of compressed air between 1.2 to 1.5 bar completely out of order To achieve the course of the threads.
  • Cardboard sizes for storing elastane have proven to be particularly suitable Cardboard boxes with the dimensions 600 mm length x 400 mm width x 500 mm height have been proven.
  • elastane threads with a titer of 10,000 dtex can be used store with a weight of 20 to 30 kg, which is a thread length of approx. 20 to Corresponds to 30 km.
  • Fig. 1 shows a modified laying device.
  • a coarse titre elastane thread with the titer 10 800 dtex, produced accordingly Example No. 6, Table 1, from DE 19 829 063 A1 was at a production speed of 120 m / min. a laying machine according to the basic scheme Fig. 1 supplied. The ribbon width was 5.1 mm. Thread 1 was over a Thread guide 2 feeds a guide roller 3, passed through an ionizer 4 and to the feed drive 5. The feed drive 5 was coated with a hard paper Roller 11 and with a rubber endless belt 12, which has two more Rolls 13, 14 is outfitted. The feed drive 5 promotes the elastane thread at 132 m / min, which is a 10% higher speed than the one delivering Production speed corresponds.
  • the thread was described as in Example 1 pulled over the feed drive at a speed of 195 m / min, which corresponds to a speed 50% higher than the production speed.
  • the feed drive was equipped with teflon-coated rollers. It was again a weak compressed air flow of 1.2 bar at two slot nozzles The hopper inlet of the hopper metered in.
  • the elastic thread became wider as in Example 1 executed, in a box 600 mm long x 400 mm wide and 200 mm highyaktafelt.
  • a total of 10 kg of elastane thread with a titer of 2,520 dtex were deposited, which corresponds to a thread length of approx. 39.7 km.
  • the thread material could be pull it out of the box for further processing without forming loops.
