The invention discloses a process for processing a polyester functional fiber which is obtained by blending a functional powder with a polyester chip, and making the polyester functional fiber by a conventional spinning process. The preparation process of the functional powder is: 10-30 parts of nano zinc oxide, 5-10 parts of titanium pigment, 3-4 parts of amino silicone oil, 5-10 parts of polyether modified silicone oil, 0.1-0.3 parts of silane coupling agent and 1-2 parts of surfactant are mixed uniformly and reacted for 3-5 hours at 50-60 DEG C. After cooling, filtering, washing and drying, the functional powder can be obtained. Keeping stirring in the course of the reaction, and the above parts are mass parts. The ratio of the functional powder and the polyester chip is: on the basis of the quality of polyester functional fiber, the functional powder accounts for 10-15%. The antibacterial function of the polyester fiber made by this process can last longer.
