Flame-Resistant Polyester Fiber Automotive Interior Materials

The DBDPE (decabromodiphenyl ethane)/Sb ₂ O ₃ flame-retardant (FR) system has been adopted to study the FR treatment of polyester (PET) fiber used in automotive interior carpet. The effect of low-temperature plasma processing was also studied. By using thermogravimetric analysis (TGA), differential thermal analysis (DTA), and cone calorimetry, tests and analyses have been done to study PET interior carpet treated in various ways. The test results show that PET carpet had better FR performance after DBDPE/Sb ₂ O ₃ treatment. Furthermore, the treated PET's FR performance was improved when low-temperature plasma treatment preceded the FR-treatment.
