Description

technical field [0001] The invention relates to the field of chemical fiber production, in particular to a method for preparing an anti-ultraviolet polyester fiber masterbatch and a method for producing polyester fibers containing the same. Background technique [0002] Polyester fiber has been widely used for its excellent physical and chemical properties since its industrialization. Due to the impact of human production and life, the earth's stratospheric ozone is destroyed, which increases the amount of ultraviolet radiation reaching the ground, which will cause certain damage to people's health. Therefore, it is very important for people's health to effectively block ultraviolet radiation and develop polyester fibers with anti-ultraviolet function. [0003] At present, the main methods for preparing anti-ultraviolet polyester fibers include fabric finishing and spinning of anti-ultraviolet polyester fibers. The fabric finishing method refers to the treatment of polyest...
