One of the most industrially important synthetic textile materials, woven poly(ethylene terephthalate) (PET) fabrics, have limitations in the usage of casual apparel applications due to their unwanted hydrophobicity. For that reason, in this study, to impart permanent hydrophilicity to the PET fabrics, hydrophilic poly(vinyl alcohol) (PVA) and a PVA‐based copolymer were introduced to the alkaline hydrolysis pretreated PET surface by graft copolymerization for the first time. The graft modification of PET fabric surface was performed with an industrial‐adaptable approach. The synthesis of a novel PVA‐g‐(N‐vinyl‐2‐pyrrolidone) copolymer was achieved by the introduction of glycidyl methacrylate monomer to the PVA backbone. The structure of the copolymer was evidenced by attenuated total reflection–Fourier transform infrared spectroscopy and 1H‐NMR techniques. The introduction of PVA and copolymer structures with desired functional groups to the PET fabric surface was confirmed with the X‐ray photoelectron spectroscopy technique. It was obtained that the contact angle–wetting time of PET fabric (145° and 98 s) could be dropped to 37° and 0.1 s and 64° and 0.7 s after PVA and copolymer grafting, respectively. This suggests that the graft‐modified PET fabrics may find the potential of use in the textile applications as the alternative hydrophilic materials. © 2019 Wiley Periodicals, Inc. J. Appl. Polym.

亲水性机织物的制备：通过接枝聚乙烯醇和聚乙烯醇-g-N-乙烯基-2-吡咯烷酮对聚对苯二甲酸乙二酯进行表面改性
在工业上最重要的合成纺织材料之一是聚对苯二甲酸乙二酯（PET）机织织物，由于其不希望的疏水性，在休闲服装应用中的使用受到限制。因此，在本研究中，为了赋予PET织物永久的亲水性，首次通过接枝共聚将亲水性聚乙烯醇（PVA）和基于PVA的共聚物引入碱水解预处理的PET表面。PET织物表面的接枝改性是通过工业适应性方法进行的。新型PVA‐ g‐（N的合成乙烯基-2-吡咯烷酮）共聚物是通过将甲基丙烯酸缩水甘油酯单体引入PVA主链获得的。衰减全反射-傅立叶变换红外光谱法和1 H-NMR技术证明了共聚物的结构。X射线光电子能谱技术证实了将PVA和具有所需官能团的共聚物结构引入PET织物表面。结果表明，在PVA和共聚物接枝后，PET织物的接触角润湿时间（145°和98 s）可以分别降至37°和0.1 s以及64°和0.7 s。这表明，接枝改性的PET织物可能会在纺织应用中找到替代亲水材料的潜力。分级为4 +©2019 Wiley Periodicals，Inc.J.Appl。Polym。科学2020，137，48584。
