Abstract (en)
[origin: EP0569889A1] A process is described for drawing a partially oriented (pre-oriented) multifilament yarn (POY). The yarn is delivered into a main drawing zone coiled around a feed godet revolving at a first speed and leaves the main drawing zone coiled around a take-off godet revolving at a second speed. The drawing in the main drawing zone takes place exclusively between the feed godet and the take-off godet, the take-off godet being heated to a temperature between 160 DEG C and 240 DEG C. The first speed and the second speed are mutually adapted to each other in such a way that the second speed is 70 % to 180 % greater than the first speed. <IMAGE>
