摘　　要：Sucrose ester( SE) was fixed on surface of poly( ethylene terephthalate)( PET) fibers to improve surface activity. Chitosan( CS) was used to graft onto pretreated PET fibers by sol-gel method. The transformations of surface chemical structure,microcosmic morphology and thermodynamic property were investigated by Fourier transform infrared spectroscopy( FTIR),X-ray photoelectron spectroscopy( XPS), scanning electron microscope( SEM), X-ray diffraction technique( XRD), and thermo gravimetric analysis( TGA),respectively. The wettability and antistatic property of PET fiber were significantly improved after modification by SE and CS.Sucrose ester( SE) was fixed on surface of poly( ethylene terephthalate)( PET) fibers to improve surface activity.
