| Abstract: | Bio-based polyamide 56(PA56)fiber was prepared by bio-based 1,5-pentanediamine and petroleum-based 1,6-adipic acid.In order to explore the thermal stability of the new type of bio-based material,the thermal degradation process of the bio-based PA56 fiber were measured under nitrogen at different heating rates,and the thermal degradation kinetic parameters were calculated.In addition,the main pyrolysis gas phase products of bio-based PA56 fiber in the thermal degradation process were analyzed.The results show that the thermal weight loss curve and kinetic parameters of bio-based polyamide 56 fiber are dependent on the heating rates.The activation energy of bio-based PA56 fiber obtained by Kissinger method,Flynn-Wall-Ozawa method and Coasts-Redfern method are 235.00,217.23 and 232.18 kJ/mol,respectively,suggesting that the thermal degradation mechanism is F1 type.The main pyrolysis gas phase products are CO2,cyclopentanone and 1,5-pentanediamine in the thermal degradation process. |
