In recent years, increasing environmental awareness and human skin protection from harmful radiation of the sun has attracted attention amongst numerous researchers. Here, a simple strategy was developed to enhance the hydrophilicity and ultraviolet (UV) protection of polyethylene terephthalate (PET) knitted fabric surface via grafting green cowpea protein (CP) with gum arabic modified epoxy (GAE) as a cross-linking agent. Chemical grafting between pretreated PET and GAE as well as between GAE and CP improved the hydrophilicity and UV protection of PET knitted Fabric. The enhanced surface wettability was confirmed by the decreased water contact angle from 135° to zero °. Moreover, the UV protection factor rating of modified PET knitted fabric was higher, indicating that the modifier layer caused scattering and absorbance of UV light. This approach has shown promising results for improving hydrophilicity and UV protection with sustained mechanical durability of 7 washing cycles.
近年来，人们对环境意识的提高以及对太阳有害辐射的人体皮肤保护引起了众多研究人员的关注。在这里，开发了一种简单的策略，通过用阿拉伯胶改性环氧树脂（GAE）作为交联剂接枝绿色豇豆蛋白（CP）来提高聚对苯二甲酸乙二醇酯（PET）针织面料表面的亲水性和紫外线（UV）防护性能。预处理 PET 与 GAE 以及 GAE 与 CP 之间的化学接枝提高了 PET 针织面料的亲水性和 UV 防护性能。通过将水接触角从 135°降低至 0°，证实了增强的表面润湿性。此外，改性 PET 针织面料的紫外线防护因子评级更高，表明改性剂层导致了紫外线光的散射和吸收。这种方法在提高亲水性和紫外线防护性能方面显示出了有前景的结果，并且具有 7 次洗涤循环的持续机械耐久性。
