Study on Structural, Mechanical and Functional Properties of Polyester Silica Nanocomposite Fabric

Polyester silica nanocomposite fabrics were prepared by incorporating different concentrations of silica nano particles to the fabric by pad-dry-cure method. The prepared composite fabrics were analyzed in terms of change in their mechanical, structural as well as their functional properties. The surface morphology showed the uniform distribution of silica nano particles on fabric through SEM, FTIR showed the presence of silica particles. Some improvement in mechanical properties observed like tensile, tearing and crease recovery angle. Improvement in functional properties observed like antimicrobial property, self cleaning, electrical surface resistivity and dyeing behavior. The most significant part of the study was that the treatment improves performance of polyester fabric without affecting the COD, BOD and TDS values.
