Abstract (en)

[origin: WO9828473A1] A process is disclosed for producing industrial yarn by stretch spinning hot spun polyester filaments at speeds from 3,000 to 6,000 m/min. The filament is stretched by a delivery device (1) and by a drafting device (2). The yarn is deflected between a delivery device (1) and a drafting device (2) and slowed down by a yarn tensioner (3) which consists of deflecting rollers (31) and (32) to a speed that satisfies the following equation: v3 = v1 + (v2 - v1) * F, in which 0.5 </= F < 1. A device having a yarn tensioner (3) between the delivery device (1) and the drafting device (2) is disclosed to carry out the process.
