초록
Polyester(PET) fabrics were treated by corona discharge equipment with the small amount of flame retardants to enhance flame retardancy. The surface properties of corona discharged fabrics were investigated using water penetration time, SEM, ESCA, and TGA. When corona discharge was applied to PET fabrics, the flame retardants were evenly distributed. As a result, the oxygen-containing functional groups were produced, and the LOI value increased. Thermogravimetric analysis indicated that the flame retardancy was operative by gas-phase mechanism.
