This creates a gradient of the preparation job the coil from the outside (high) to the inside (low).
  • Elastane threads or elastanes are understood to mean fibers or threads which are at least 85% by weight of segmented polyurethanes or polyurethane ureas consist.
  • the elastic and mechanical properties of such fibers are achieved in that, for example, polyurea-polyurethanes are used to produce the elastane threads from aromatic diisocyanates can be used.
