Abstract:The thermal performances of four kinds of chemical fiber included tencel fiber, polyster fibre, polypropylene fiber and aramid fiber were studied by using DSC and TG, their characteristics of phase transition and thermal decomposition in the heating-up process were compared, and the thermal decomposition kinetics models of the four kinds of fiber were established by using Kissinger method , their apparent activation energys were respectively calculated as the follows: 128.66 kJ/mol, 125.12 kJ/mol, 153.58 kJ/mol, 211.19 kJ/mol. |
