Abstract (en)

[origin: EP0124454A1] 1. Process for improving the structural uniformity of filaments based on thermoplastic polymers, obtained by melt-spinning and continuous drawing between a take-off roll and a drawing roll, characterised in that the drawing stress (represented as the ratio of the tension force to the count at the time of the measurement) is measured and controlled at a constant level, the speed of the drawing roll being kept constant.
