PET fabric was grafted with or plasmas generated by glow discharge. The water repellency of plasma-treated fabrics were evaluated with contact angle meter. The change in surface morphologies was observed by SEM, and the change of surface chemical characteristics were analyzed by FT-IR, ESCA and microchemical analysis technique. The results obtained are as follows : 1) The contact angle of plasma-treated fabric was over . 2) It was observed by SEM that the surface of treated substrate was over coated with thin film formed by the fluorocarbon plasma treatment. 3) According to ESCA analysis, there were prevailing -CHF-, - and a little components on fluorocarbon plasma treated substrate. -CHF- and - components were reduced by washing, and - component was recovered by heat treatment. 4) In consideration of quantitative analysis of fluorine and F/C ratio by ESCA, we found that fluorination reached to the inner of substrate. |
