Ethanediamine (EDA) and sodium hydroxide was applied to modification of polyester fabric which made the surface of polyester rich in amino groups. Then the modified polyester dipping with graphene oxide (GO), obtained conductive materials by reducing GO to reduced graphene oxide (RGO). The samples were characterized by SEM. The rubbing and washing fastness of the samples were also tested. The results showed that the absorption performance of polyester was increased obviously after modified with EDA. The optimal conductive finishing process was pH of GO 6, sodium hydrosulfite 5g/L, reducing at 95℃ for 60min. The conductivity of polyester fabric increased with the increasing of the concentration of GO, reducing temperature and time. When the GO concentration was 2g/L, the surface resistance value of the modified polyester decreased to 14.575 KΩ/cm. The SEM was showed that the surface of original polyester fabric is smooth, after dipping with GO, GO forms a thin film on the surface of the fabric.
