PET fabric was treated by R.F. plasma of $C_2F_6$ , and PET film was also treated by the same method. The treated samples were washed with boiling water in soxhlet apparatus for 4 hrs, dried at room temperature for 48 hrs, and heat treated at 15$0^{\circ}C$ for 10 mins. In order to investigate the most optimum treatment condition, plasma gas pressure and treatment time were systematically changed. The water repellent property of plasma treated samples were evaluated by contact angle meter and water droplet rolling-off angle meter. And the change of surface chemical characteristics were analyzed by ESCA. The results obtained are as follows: 1) Before washing the PET film contact angle appeared high near two electrodes, however, after washing and heat treatment were done, the more effective setting position of substrate was the center area of the reactor. 2) The contact angle of $C_2F_6$ treated samples was higher than 150$^{\circ}$irrespective of plasma gas pressure, and under low pressure and short time treatment condition $C_2F_6$ plasma treatment was more effective than $CF_4$ plasma treatment. 3) There was a good water repellency when $C_2F_6$ gas pressure is 0.05~0.06 torr and duration of glow discharge treatment is 60~90 seconds. 4) According to ESCA analysis, $-CF_2-$ , and $-CF_3$ bonds were more readily formed by the $C_2F_6$ plasma rather than by the $CF_4$ plasma of $C_2F_6$ treated sample, and the $-CF_2-$ bond appeared to be dominant with short time treatment condition.
