Abstract
A process for producing a highly oriented, partially drawn, untwisted, compact poly(.epsilon.-caproamide) yarn at windup speeds of from 3500 to 6000 meters per minute is disclosed. The process features the steps of overfeeding the yarn, by from 0.5 to 2.0 percent, to entangling means, and overfeeding the shrinking yarn to the winder. The yarn is 'drawn' in the quench stack. Draw-twisting is omitted by this process; yarn so produced performs as well as conventional, draw-twisted yarn in end use applications, e.g., knitting and weaving.
