Antibacterial And UV Protection Properties Modified Cotton Fabric Using Curcumin/ TiO2 Nanocomposite For Medical Textile Applications

Abstract

Medical textiles are one of the most rapidly growing parts of the technical textiles sector of the textile industry. This work was developed for biocompatible materials of curcumin / TiO2 nanocomposite fabricated on the surface of cotton fabric for medical applications. Cotton fabric was pretreated with three crosslinking agents namely, citric acid, Quat-188, and GPTMS. Applying nanocomposite on modified cotton fabric using pad-dry cure method. The chemistry and morphology of modified fabrics are examined by Fourier-transformed infrared spectroscopy, energy-dispersive X-ray spectroscopy, and scanning electron microscopy. In addition, the chemical mechanism for nanocomposite modified fabric was reported. UV protection (UPF) and antibacterial properties against Gram - positive S. aureus and Gram - negative E. coli bacterial strains were investigated. The durability of fabrics to 20 washing cycles was also examined. Results demonstrated that nanocomposite modified cotton fabric exhibited superior antibacterial activity against Gram - negative bacteria that Gram - positive bacteria and excellent UV protection properties. Moreover, good durability was obtained, possibly due to the effect of the crosslinker used. Among the three pre-modification of cotton fabric, Quat-188 modified fabric reveals the highest antibacterial activity comparing with citric acid or GPTMS modified fabrics. This outcome suggested that curcumin / TiO2 nanocomposite Quatt-188 modified cotton fabric could be used in biomedical textile as antibacterial properties.
