Levels of stain and discoloration of PET flakes are electrically measured to investigate quality evaluation methods. As electrical characteristics for evaluation, amounts of electrical resistance, electric charge, dielectric constant, dielectric tangent, etc. are taken as objectives. We have analyzed stains of PET flakes, made samples of loss products with stain and measured electrical resistance and an amount of electric charge. We have also measured dielectric constant and dielectric tangent of PET flakes. Possibility of evaluating surface conditions of PET flakes from the above physical properties measured has been elucidated.
