“…Although there have been numerous studies for the graft modification of PET fiber/fabric in the literature, to our knowledge, no report has been present for the grafting of a PVA based‐copolymer or PVA onto PET fabrics. Only in a few studies, the preparation of PET/PVA composites and radiation‐induced graft copolymerization of vinyl acetate onto PET were reported . In the other recent studies, the researchers have focused on the improvement of the other properties of PET fabrics, such as thermoregulating and anti‐oil staining with different materials, such as coating with phase‐changing materials and photografting of poly( N ‐isopropyl acrylamide), respectively.…”

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.

SUMMARY:Polyester (PETP) fibres were grafted with poly(viny1 acetate) (PVAC) and poly-(vinyl alcohol) (PVAL). The graft content was varied from 5 to 30%, and the effects of grafting on the morphological characteristics were evaluated using infrared spectroscopy, X-ray diffraction and optical birefringence techniques. The crystallinity index, crystalline orientation function, crystal latice parameters such as Bragg angles and interplanar spacings, and crystallite size were not changed in graft copolymers PVAC and PVAL, implying thereby that no transformation of unit cell parameters had taken place due to grafting. The crystalline orientation (X-ray orientation function) in both the cases was not changed. The amorphous orientation function decreased with increase in poly(viny1 acetate) whereas in the case of PETP-g-PVAL it initially decreased up to about 12% PVAL and then showed an increase.ZUSAMMENFASSUNG: Polyesterfasern (PETP) wurden mit Polyvinylacetat und Polyvinylalkohol gepfropft. Der Pfropfgehalt wurde zwischen 5 und 30% variiert, und die Einfliisse des Pfropfens auf die Morphologie wurden mittels IR-Spektroskopie, Rdntgenbeugung und optischer Doppelbrechung ausgewertet.Der Kristallinitatsindex, die kristalline Orientierungsfunktion, Kristallgitterparameter wie Bragg-Winkel, Gitterebenenabstande und KristallitgrdDe wurden nicht beeinfluDt durch die gepfropften PVAC und PVAL-Copolymeren, was darauf hinweist, dal3 keine Anderung der Elementarzelle durch das Pfropfen stattfand. Die kristalline Orientierung (Rdntgenorientierungsfunktion) hat sich in beiden Fallen nicht geandert. Die amorphe Orientierungsfunktion erniedrigte sich mit der Zunahme von Polyvinylacetat, wahrend sie im Falle von mit PVAL gepfropften Polyesterfasern anfanglich abnahm bis etwa 12% PVAL und dann einen Anstieg zeigte.
