| 摘要:利用差热扫描量热法和热重分析法对天丝纤维、涤纶纤维、丙纶纤维及芳纶纤维等4种常用化学纤维的热性能进行研究，探讨了这4种化学纤维在升温过程中的相变以及热分解特性并将之进行对比，同时通过Kissinger法建立4种化学纤维的热分解动力学模型，求得4种化学纤维的表观活化能分别为：128.66、125.12、153.58、211.19 kJ/mol。 |
| 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. |
