Effect of Plasma Pretreatment Followed by Nanoclay Loading on Flame Retardant Properties of Cotton Fabric

摘要

In this research work the effect of plasma treatment with nitrogen gas followed by nanoclay treatment on flame retardancy of cotton fabrics is studied. The flame retardancy of the samples was characterized by limiting oxygen index and the char yield. The thermal decomposition behaviors, the chemical structures and morphologies of the fabrics were investigated using thermo gravimetric analysis, Fourier transform infrared and scanning electron microscopy, respectively, and a possible flame retardant mechanism is discussed. It shows that, nitrogen plasma pretreatment has synergistic effect on nanoclay for improving the flame retardant properties of cotton samples.
