Abstract: A continuous high speed spin-draw-false twist texturing process for producing a textured nylon yarn having high yarn uniformity is disclosed. The process comprises the steps of (a) melt-spinning a plurality of nylon filaments from nylon polymer; (b) cooling the filaments and combining them to form a yarn; (c) controlling the processing conditions of the nylon polymer of step (a) such that the relative viscosity of the yarn formed in step (b) is at least 45; (d) partially drawing the yarn at a draw ratio of from 2.3 to 3.5 and a temperature of at least 50.degree. C.; (e) simultaneously false twist texturing and further drawing the partially drawn yarn in a draw-false twist texturing zone at a draw ratio of from 1.1 to 1.5; and (f) withdrawing the textured nylon yarn at a speed of at least 1500 meters per minute. The process is particularly useful for the manufacture of textured nylon yarn having a linear density in the range of from about 10 dtex to about 50 dtex.
