  • This preparation oil is not evenly along of the thread, but on the outermost, in particular at least 3% amount of the thread wound on the tubes significantly increased so that the oil application in this area is at least 1.2 times higher than in the rest Area of the coil. 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.
  • Elastanes are usually made by spinning solutions using the wet spinning process or preferably produced by the dew-spin process.
  • Solvents are suitable in both processes, polar solvents, e.g. B. dimethyl sulfoxide, N-methylpyrrolidone, dimethylformamide or preferably dimethylacetamide.
  • Silicone oil on the elastane thread must be done with high uniformity to ensure that the thread is equally sticky at every point on its bobbin travel (Liability) both towards the thread layers on the bobbin, of which it is must replace, as well as against the thread guide elements of the processing machines has.
  • Maruyama et al in JP 63-66073 go on the uniformity of the oil application even so far, the different stretching of the elastane thread inside the Take the coil into account when applying the oil.
