Abstract (en)
A manufacturing method of polyester fiber having improved light fastness is provided, which comprises copolymerizing dicarboxylic acid, diol component and the ester forming monomer into a copolyester, wherein said ester forming monomer is present in an amount of 0.05 mole % above based upon the total dicarboxylic acid components and is represented by the following formula (1) R2OOC-R1-COOR3 (wherein R1 is a naphthalene ring, R2 and R3 are selected from group of hydrogen atoms or C1 SIMILAR C4 alkyl, and R2 is independent from R3, it can be the same or different with R3; the position of substitute group for the naphthalene ring on the ester forming monomer can be: -2,3-, -2,5-, -2,6-, -2,7-, -1,2-, -1,3-, -1,4-, -1,5-, -1,6-, -1,7-, -1,8-), subjecting the formed copolyester component to spin-draw process to obtain fiber which possess excellent light fastness after dyeing. Said fiber is suitable for automobile interior decoration, curtain and outdoor application and can keep fresh color without fading even being exposed to sunlight for a long time.
