Abstract
(EN)
The present invention relates to a method for producing wholly aromatic liquid crystalline polyester fibers having improved spinning properties, and more specifically, to a method for producing wholly aromatic liquid crystalline polyester fibers by pelletizing a resin and melt spinning the resin under an oil condition in which 0.5-2% of a coning oil and 0.5-2% of a high-temperature silicone spin finish oil are mixed using water as a solvent, wherein the resin is produced by adding 0.08-1.12 equivalent weights of acetic anhydride to raw material monomers comprising hydroxy benzoic acid, hydroxy naphthoic acid, bi-phenol, terephthalic acid, and isophthalic acid, and subjecting same to solid state polycondensation.
(FR)
La présente invention concerne un procédé permettant de produire des fibres de polyester cristallin liquide entièrement aromatique ayant des propriétés de filage améliorées et concerne, plus particulièrement, un procédé permettant de produire des fibres de polyester cristallin liquide entièrement aromatique par granulation d'une résine et filage par fusion de la résine dans un état d'huile dans lequel de 0,5 à 2 % d'une huile de bobinage et de 0,5 à 2 % d'une huile d'ensimage de filature de silicone à haute température sont mélangées à l'aide d'eau en tant que solvant, la résine étant produite par ajout de 0,08 à 1,12 de poids équivalent d'anhydride acétique à des monomères de matière première comprenant de l'acide hydroxybenzoïque, de l'acide hydroxynaphtoïque, du biphénol, de l'acide téréphtalique et de l'acide isophtalique, et par soumission de ladite résine à une polycondensation à l'état solide.
