Definitions

  • Spinning delay V is defined as the ratio of take-off speed A to ejection speed S:
  • the preparation is expediently brought into contact with the individual thread ribbons at elevated temperatures of 50-90 ° C. in order to prevent the hot thread sheet from cooling.
  • the manhole tapes spun from a spinning machine with, for example, 20 spinning shafts, with a total titer of 100,000 dtex and more, are prepared in this way, bundled after leaving the fusing unit and directly subjected to further post-treatment, e.g. B. with the process steps stretching - crimping - shrinking - cutting.
  • the warm acrylic cable with a total titre of 344,000 dtex still has a residual solvent content of 0.8% by weight of DMF.
  • the cable can then be stretched, crimped, shrink and cut into staple fibers.
