Abstract
Process for the manufacture of synthetic linear polymer yarns endowed with previously established characteristics of tenacity and residual elongation consisting in stretching the yarn slightly higher than that corresponding to the previously established final characteristics between two yarn advancement arrangements in the second wherein the yarn has a higher speed than the first in the proportion corresponding to the desired draw and heat a part of at least the second yarn advancement arrangement at a temperature not appreciably above 40º below the melting point of the polymer .
