摘要：

The thermal degradation in air of hemp fabric treated with various compounds containing nitrogen, phosphorus, halogens, and boron, in combinations of two compounds, has been studied by differential thermal analysis and thermogravimetry from ambient temperature to 600degreesC. The kinetic parameters were obtained using the equation of Broido. The values of activation energies for the oxidative decomposition of samples were found to be in the range 52-102 KJmol(-1). Hemp fabric treated with flame retardants showed a high limiting oxygen index and char yield which indicated that the flame retardance of treated hemp was improved. Effect of the different elements on degradation behaviors has been proposed.
