Abstract The polyester (PET) fabrics' hydrophilicity can be improved by electron beam (EB) irradiation initiated grafting hydrophilic monomers. But the high regularity and crystallinity of the PET macromolecule structure results in the inferiority in the modification effect and grafting ratio compared to other common synthetic fibers. In this paper, the introduction of plasma pretreatment prior to EB irradiation has been proved to be able to greatly promote the effect of EB irradiation grafting modification according to the tests on the grafting ratio, moisture regain, contact angle, infrared spectrometer, and scanning electron microscopy (SEM) of the PET fabrics without any treatment, the EB irradiated PET fabrics without pretreatment and the EB irradiated PET fabrics with plasma pretreatment respectively. The results showed that the grafting ratio increased by 1.64 times, the moisture regain increased by 75%, and the contact angle decreased quickly from 87.95°to an unmeasurable small value, indicating the further improved hydrophilicity compared with the modified PET fabrics without plasma pretreatment. In addition, the influences of strength loss and the decrease of whiteness due to the plasma pretreatment on PET fabrics are almost negligible.
