We modified the poly(ehtylene terephtalate) (PET) wire meshes with hydrophilic monomers by the electron beam irradiation induced graft-polymerization method, to protect the PET meshes from pitch stain in papermaking process of recycled papers. Di-hydroxyethyl methaclylate (HEMA) with the hydroxyl group, acrylic acid (AA) with the carboxylic group, acrylamide with the amide group and glycidyl methacrylate (GMA) with the epoxide group were used for grafting onto the fiber surfaces of the PET meshes. Grafting efficiency and hydrophilic property were studied by means of grafting ratio and FTIR spectra and by contact angle of water, respectively. As a result, PET mesh which di-hydroxylated after GMA grafting was found to show the most hydrophilic properties.
