Abstract
(EN)
The present invention relates to complete extinction polyester drawing yarns and a preparation method thereof. The preparation method comprises: preparing modified polyester FDY yarns, i.e., complete extinction polyester drawing yarns, from a modified polyester melt according to an FDY process; the preparation method of the modified polyester comprises: uniformly mixing terephthalic acid, ethylene glycol, 2,5,6,6-tetramethyl-2,5-heptandiol, fluorine-containing binary acid, an extinction agent, multiphase solid acid-base powder roasted at a high temperature, and doped and modified Bi2O3 powder; and then successively performing esterification reaction and polycondensation reaction. The intrinsic viscosity of a prepared product placed for 60 months at a temperature of 25°C and relatively humidity of 65% is reduced by 18-25%. The preparation method of the present invention is simple in process. By adding the 2,5,6,6-tetramethyl-2,5-heptandiol, the fluorine-containing binary acid, doped and modified Bi2O3 powder, and the multiphase solid acid-base powder roasted at a high temperature, the degrading performance of the prepared product is improved.

La présente invention concerne des fils d'étirage de polyester à extinction complète et leur procédé de préparation. Le procédé de préparation consiste à : préparer des fils de polyester FDY modifiés, c'est-à-dire des fils d'étirage de polyester à extinction complète, à partir d'une masse fondue de polyester modifiée selon un procédé FDY ; le procédé de préparation du polyester modifié comprend les étapes consistant à : mélanger uniformément de l'acide téréphtalique, de l'éthylène glycol, du 2,5,6,6-tétraméthyl-2,5-heptanediol, un acide binaire contenant du fluor, un agent d'extinction, une poudre à base d'acide solide multiphase grillée à haute température et de la poudre de Bi2O3 dopée et modifiée ; puis réaliser de manière successive une réaction d'estérification et une réaction de polycondensation. La viscosité intrinsèque d'un produit préparé placé pendant 60 mois à une température de 25 °C et une humidité relative de 65 % est réduite de 18 à 25 %. Le procédé de préparation selon la présente invention est de processus simple. En ajoutant le 2,5,6,6-tétraméthyl-2,5-heptanediol, l'acide binaire contenant du fluor, la poudre Bi2O3 dopée et modifiée et la poudre de base d'acide solide multiphase grillée à haute température, la performance de dégradation du produit préparé est améliorée.
