METHOD AND DEVICE FOR PRODUCING A MULTIFILAMENT THREAD

摘要

The invention relates to a method and a device for producing a multifilament thread from a polymer melt. The freshly extruded filaments are initially cooled and combined to form a thread. In order to obtain an improved thermal shrinkage fixation to the thread, the thread is post-treated with a heated preparation fluid after having undergone the stretching and relaxing by a plurality of galette groups with several guide jackets.
