Part I: Characterization of Flammability Behavior of Polyester Fabric Modified with Sol-Gel

Polyester (PET) fabric is insecure to use since it melts at 249–290 °C, such molten PET could drip on underlying surfaces or human skin and hence become harmful. The rapidly ignited and flammable materials found in nearby areas might lead to damage life and property of consumers. In this research, the fabric was modified to avoid these disadvantages. Thus we investigate the effect of phosphorylated sol-gel coating material on UV/Ozone pre-modified polyester sample for different periods. The thermogravimetric analysis (TGA) and ignition properties (UL/94) were studied for all samples under test. The samples with phosphorylated sol-gel material improved the flammability behavior. Also, the use of UV/Ozone prior this modification activate the surface of polyester, thus improved the stability of the flame retardant.
