Beschreibung
Zusammenfassung:	The present invention relates to a method for manufacturing an elastic yarn (20) by melt spinning by means of a spinning machine (1) comprising an extruder (2) and a spin pack (3) comprising at least one die (19), said method comprising at least the following steps: a preliminary cold drawing of the yarn (20) at the outlet of the die (19), followed by a hot drawing of the yarn (20) then by a cold drawing of the yarn (20). The invention also relates to a textile comprising such an elastic yarn and to a plant configured to implement this method.
