Abstract (en)
[origin: EP0731196A1] A process for spinning, drawing and winding a synthetic thread includes subjecting the thread (1) to heat treatment between drawing and winding to minimise tendency to shrink. The thread is led close to, but not touching a long heated surface at a temp. pref. 100 K, more pref. between 200 and 300 K higher than the thread m.pt. and is subject to a tension lower than that to cause plastic deformation, i.e. pref. less than 0.3, more pref. between 0.1 and 0.2 cN/dtex. The wound thread has a tendency to heat, or boiling, shrinkage of more than 3%. Also claimed is a machine for the process comprising an unheated Godet wheel (54) for drawing off the thread from the stretching zone and, following the Godet wheel and before winding, a heater (8) providing the long heated surface at the temp. required.
