摘要： An improvement is provided in an integrated process for the production of textured multifilament yarn from a fiber-forming, thermoplastic, linear, high-molecular-weight polymer by the combination in immediate succession of the procedural steps of melt spinning, drawing, texturing, and packaging. The present improvement combines the following procedural steps with those of melt spinning, drawing, texturing, and packaging:

(1) Lubricating the filamentary polymeric material from the melt spinning step by applying thereto a lubricating composition containing (a) a lubricant, and (b) solvent in an amount of from 0 to 90 percent by weight of the lubricating composition;
(2) Pre-tensioning the lubricated melt spun filamentary polymeric material beyond its elastic limit at a temperature between about 20 and 60°C prior to the drawing thereof; followed by
(3) Pre-heating the pre-tensioned filamentary polymeric material to a temperature between about 30 and 100°C prior to the drawing thereof.
