Method of drawing using singular godet rollers |
摘要 |
A method is described of drawing a pre-oriented multifilament yarn (POY yarn). Hereby the multifilament yarn is fed from a delivery godet, around which it is wrapped, at a first velocity into a main drawing zone and removed from the main drawing zone at a second velocity by a drawing-off godet around which it is wrapped. The drawing in the main drawing zone takes place between the delivery godet and the drawing-off godet whereby the drawing-off godet is heated to a temperature of between 160 DEG C. and 240 DEG C. The first and the second velocities are so adjusted with respect to each other that the second velocity is 70% to 180% greater than the first velocity.
