In this studs, we synthesized durable antistatic agents with acrylic monomers for preventing the electrification of static electricity which is one of defects of polyester fabrics. Also we synthesized quaternary ammonium salts which give antistatic property and crosslinking agents which make antistatic agents adhere to fiber. The treatment of synthesized antistatic agents on polyester fabric carried out at the condition of various concentrations, treatment times and temperatures. The antistatic property, handle characteristics and other properties of treated and untreated polyester fabrics were also investigated.
