Based on the principle of synergistic function of organic and inorganic anti-UV agents, the compound of anti-UV radiation agents was studied for the preparation of anti-UV polyester in this paper. The effect of anti-UV agent proportion in the reaction mixture related to the physical and chemical character of polyester and its fibre, especially the spinning flexility and anti-UV radiating property, was studied in detail. Also, the catalyzing function of the anti-UV agents in the polymerization was discussed. Furthermore, the feasible temperature of the polymerization was obtained. The textile product in test showed excellent flexility and the whole polymerization process is feasible to industry manufacture. The anti-UV property of the final product accords with the technical standards described in AS/NZS 4399： 1966.
