In this paper, the surface finishing process of anti-alcohol, anti-oil and antistatic was applied on terylene needle-punched nonwoven filter material. We used contact angle, anti-alcohol grade, anti-oil grade, static voltage and half-life period as the main indicators for evaluating the effect of the finishing. The organic fluorine TG-410C and nonionic antistatic agent TF-481 were selected as finishing agents. The single factor experiments and orthogonal experiments were carried out on four effect factors of the finishing, including volume percent of organic fluorine, volume percent of antistatic agent, baking temperature, baking duration. The results show an optimum formula: the volume percent of organic fluorine is 20%, the volume percent of antistatic agent is 15%, baking temperature is 170°C, and baking duration is 7min. After finishing, anti-alcohol grade can reach level eight, anti-oil grade can reach level five; the half-life period is less than 1 second. So it can be employed in filtering the air and reducing dust particle and concentration.
