ABSTRACT:
The invention is related to a process for the stretch-texturing of high-molecular weight linear synthetic endless filaments travelling at speeds of 300 to 1200 meters per minute by continuously guiding the filaments through a delivery zone, a heat-fixing zone, a false-twister and a stretching godet. The endless filaments are passed through a stretching zone S 55 to 180 cm long, defined by the distance between the delivery stage and the stretching godet, the distance between the delivery stage and the false-twister inlet amounting to S-X cm and the distance X between the false-twister outlet and the stretching godet being 5 to 30 cm.
