Title
(EN) METHOD FOR MODIFYING THE COLOR-HUE OF COLORED SYNTHETIC YARNS AND FILAMENTS, AND SYSTEM FOR CARRYING IT OUT
(FR) PROCÉDÉ DE MODIFICATION DE LA TEINTE DE COULEURS DE FILS ET DE FILAMENTS SYNTHÉTIQUES COLORÉS, ET SON SYSTÈME DE MISE EN ŒUVRE
Abstract
(EN)
The invention provides a method for modifying the color hue of already colored synthetic yarns and/or filaments in a conventional melt-spinning process, which allows correcting deviations from tolerances in the color hue by the manufacturers themselves. The method comprises storing color coordinates of a target hue; measuring color coordinates of colored yarns and filaments to be corrected; comparing the data to provide deviations beyond tolerances; preparing a correcting-liquid-masterbatch composition; converting the deviations beyond tolerances into a dose of the correcting liquid-masterbatch composition; and adding such dose to molten mass of the synthetic yarns and filaments. The invention is also directed to a system suitable for performing the method of color hue modification and/or correction.
(FR)
L'invention concerne un procédé de modification de la teinte de couleurs de fils et/ou de filaments synthétiques déjà colorés au cours d’un procédé classique de filage par fusion, qui permet de corriger des écarts de tolérances concernant la teinte de couleurs par les fabricants eux-mêmes. Le procédé comprend le stockage de coordonnées chromatiques d'une teinte cible ; la mesure de coordonnées chromatiques de fils et de filaments colorés à corriger ; la comparaison des données pour obtenir des écarts au-delà des tolérances ; la préparation d’une composition de mélange maître liquide de correction ; la conversion des écarts au-delà des tolérances en une dose de la composition de mélange maître liquide de correction ; et l’ajout d’une telle dose à la masse fondue des fils et filaments synthétiques. L'invention concerne également un système approprié pour mettre en œuvre le procédé de modification et/ou de correction de teinte de couleurs.
