Abstract
Improved process for obtaining stretched multifilament polyester yarn, provided with a permanent ripple, especially of a yarn of uniformly crimped ethylene polyterephthalate, with very constant mechanical properties and affinity to the dye, 1 comprising the melt spinning operations of polyterephthalate ethylene to form filaments and, subsequently, preheat, stretch and curl the filaments, characterized by a) melt-spinning the polyester filaments at spin speeds between 1200 and 4000 m/min., collecting the freshly spun filaments at a speed substantially the same as the spinning, in order to achieve a thread consisting of a polymer with characteristics of high density but not exceeding 1.3500 and birefringence, also high, not less than 90x10-4 and b) after preheating, stretching and simultaneously curling said filaments by means of a false twisting device disposed between s pairs of feeding and drawing rollers, respectively.
