Abstract

L'invention concerne un procédé et un dispositif de production de fils synthétiques complètement étirés (FDY) par étirage et relâchement de plusieurs fils venant d'être filés. Les fils filés par un dispositif de filage et consolidés par un dispositif de refroidissement sont guidés conjointement sous la forme d'une nappe de fils à la périphérie de plusieurs enveloppes de galette entraînées. Les fils sont en contact avec les enveloppes de galette par un enroulement partiel <360°, les fils situés sur les surfaces des enveloppes de galette étant traités thermiquement et guidés librement entre les enveloppes de galette avec au moins une différence de vitesse. L'invention vise à pouvoir produire des fils présentant une aptitude à la teinture d'excellente qualité. A cet effet, les fils sont étirés selon l'invention entre une première enveloppe de galette chauffée et une deuxième enveloppe de galette chauffée dans un parcours de tension libre puis guidés et relâchés entre la deuxième enveloppe de galette chauffée et une troisième enveloppe de galette chauffée dans un premier parcours de relâchement libre et guidés et relâchés entre la troisième enveloppe de galette et une quatrième enveloppe de galette dans un deuxième parcours de relâchement libre. Les fils étirés, afin d'être relâchés avec une longueur de contact totale, reçoivent un traitement thermique sur les enveloppes de galette, la longueur de contact étant supérieure d'un multiple dans la plage de trois à sept à une longueur de fil libre de l'étirage relâchement. Et la deuxième, la troisième et la quatrième enveloppe de galette sont chauffées à une température de surface dans la plage de 120°C à 250°C, de préférence de 150°C à 250°C.
