Electron beam (EB) irradiation has been utilized to modify materials for various applications due to its remarkable advantages. As an efficient and environmental-friendly way for antibacterial and hydrophilic purposes, EB irradiation was applied to modify polyethylene terephthalate (PET) fabrics by grafting with a N-halamine precursor monomer 3-allyl-5,5-dimethylhydantoin (ADMH) and acrylic acid (AA) in this study. The grafted PET fabrics were loaded with silver ions to further enhance the antimicrobial efficacy. The hydrophilicity of the modified PET fabrics was evaluated by testing the water contact angles with different contact times. The breaking strength and thermal stability of the modified swatches were studied. The UVA light stability results showed the chlorine loading of the modified PET fabrics decreased with the extension of UVA exposure time, and most chlorine loading could be recovered by re-chlorination. The antibacterial test showed that the modified PET swatches can inactivate all inoculated S. aureus and E. coli with short contact times.

由于其显着的优势，电子束（EB）辐射已被用于修饰各种用途的材料。作为用于抗菌和亲水目的的一种有效且环保的方法，EB辐射通过与N-卤胺前体单体3-烯丙基-5,5-二甲基乙内酰脲（ADMH）和丙烯酸接枝来改性聚对苯二甲酸乙二醇酯（PET）织物。 （AA）。接枝的PET织物上装有银离子，以进一步提高抗菌效果。通过测试不同接触时间下的水接触角来评估改性PET织物的亲水性。研究了改性样品的断裂强度和热稳定性。UVA的光稳定性结果表明，改性的PET织物的氯含量随UVA暴露时间的延长而降低，并且大部分氯含量可以通过重新氯化来恢复。抗菌测试表明，经过修饰的PET色板可以灭活所有接种的金黄色葡萄球菌和大肠杆菌的接触时间短。
