Abstract

L'invention concerne un procédé de production d'une fibre de térylène en utilisant des déchets de polyester. Des déchets de polyester séchés sont d'abord envoyés dans une extrudeuse à vis, puis fondus et extrudés pour donner une coulée de polyester. Ladite coulée est ensuite filtrée deux fois pour éliminer les impuretés. Une réaction de polymérisation de macromolécules a ensuite lieu dans la coulée de polyester en vue d'homogénéiser le poids moléculaire du polymère macromoléculaire et d'accroître la viscosité du polyester. La coulée de viscosité accrue est alors finement filtrée à l'aide d'un filtre à coulée de précision. Ensuite, la coulée est envoyée dans un caisson de filage pour exécuter un filage par doses, puis est refroidie et solidifiée en filaments. Enfin, les filaments sont enroulés selon diverses exigences de processus. Le procédé est susceptible d'améliorer la qualité de la coulée de filage en polyester de récupération. La coulée de polyester de récupération présente moins d'impuretés et une viscosité homogène après filtrations multiples. Le produit en fibre présente les avantages d'un moindre taux de cassures aux extrémités, d'un taux élevé de bobines pleines, d'un débit élevé de produits finis et de pertes réduites.
